Andhikhola Storage Hydroelectric Project Executive Summary
EIA-Report vii NEA-ESSD
EXECUTIVE SUMMARY
1. Introduction
Nepal Electricity Authority (NEA) is the project proponent of the proposed Aandhikhola Storage
Hydroelectric Project (AKSHEP). This project was identified as one of attractive projects in
1997. The proponent has obtained survey license from Department of Electricity Development
for feasibility and environmental study of a storage hydroelectric project in Aandhikhola on
2074/02/04 BS. Environment and Social Studies Department (ESSD) of NEA has been
preparing the EIA study report of the project as per the Environmental protection Act, 2076,
Environment Protection Regulation 2077 and other prevailing laws. The main objectives of the
EIA are to collect baseline information of the project area, predict likely physical, biological and
social impacts and figure out mitigation/enhancement measures and monitoring plan.
The Scoping Document (SD) and Terms of Reference (ToR) of the EIA report have been
approved by Ministry of Forests and Environment (MoFE) on 2075/10/14 BS. This EIA
document has been prepared as per the prevailing laws of Nepal as well the approved SD and
ToR documents.
2. Project Description
The proposed project has installed capacity of 180 megawatt. It is a storage type project with
167 m tall dam having 341 million cubic meter of live storage capacity. The dam will create a
reservoir of 7.52 square km extending about 21 km backwater. The project utilizes a gross
head of 328.6 m by diverting the Andhikhola flow through a 3.1 km long tunnel to a semi
surface powerhouse. Design discharge of the scheme is 73 cubic meter per second. The
proposed intake site is located about 600m northwest from Guthi, Galyang Municipality-2 and
left bank of Andhikhola. The powerhouse is located at Chharti on the left bank of Kaligandaki,
about 3 km south of Upper Galyang Bazaar.
The project-affected areas are Galyang Municipality, Waling Municipality and Kaligandaki Rural
Municipality of Syangja district and Rambha Rural Municipality of Palpa district. AKSHEP is
located about 234 km west of Kathmandu. The existing Siddhartha highway and the Kali
Gandaki ‘A’ access road provides easy access to the project site. About 7.545 km access road
should be constructed to make all the project components accessible.
The project components consist of headworks (dam, spillway, intake, and reservoir), headrace
tunnel, surge shaft, pressure tunnel (penstock), powerhouse, tailrace, access road,
transmission line etc. The powerhouse accommodates three turbine generators units each with
a capacity of 60 MW. So, the total power generation will be 180 MW. The power plant will
generate 674 GWh, with dry energy of 273 GWh and wet energy of 401 GWh. Generated
power from the AKSHEP will be evacuated through the 220 kV transmission line to the nearest
tower of Kaligandaki Corridor Transmission Line, which will be about 8 km long. The project is
optimized to run daily 8 hrs 15 min in full capacity in dry season and 3 hrs 30 min to 18 hrs in
rainy season.
The anticipated project construction period is 5 years including 20 months of preparation
period. The total workforce including skilled, semi-skilled and unskilled labor during construction
period is estimated to be 1200. Based on the preliminary design of project components, total
estimated project is USD 498.496 Millions (NRs 56 Billion).

3. Study Methodology
The EIA report preparation process follows prevailing environmental act/rules and National EIA
Guidelines, 2050 as well the approved Scoping and ToR document. This EIA is prepared in
accordance with the legal requirements of GoN, based on field studies and consultation with
local people and officials. For this report, data and information was collected from primary as
well as secondary sources. For the project impact assessment, the project area was delineated
as Direct Impact Area and Indirect Impact Area. During field walkthrough survey, field
observation, GIS analysis, forest inventory, consultation with local people and stakeholders,
interview, group discussion, household survey, identification of Project Affected Families etc
were done. Field visit of this study was done in 2076 Bhadra.
Climatic data (temperature and rainfall) of the project nearby area were colletcted from
secondary sources. Water samples from dam (Andhikhola) and powerhouse (Kaligandaaki
River) area were tested in a high tech laboratory in Kathmandu for different parameters. Air and
noise quality were also measured at the project sites.
Forest inventory of the project impact area was done in coordination with DFO and Sub-DFO
office of syangja district. Following Community Forestry Resource Inventory 2061, sampling
survey was choosen to assess forest and vegetation of reservoir and powerhouse area. During
the sampling process, all types of plants and vegetation within the plot were identified and their
DBH and height were measured. Similarly, fish and aquatic life of andhikhola and kaligandaki
were studied twice in dry and rainy season.
To study socio-economic and cultural environment of the project impact area, affected
households were identified and 1144 households were surveyed. Public and private structures
within the reservoir area were measured. In addition, information were collected through FGD,
market survey, key informant survey, identification of project affected religious and cultural
sites.
Data and information were analyzed, interpreted and compiled to prepare a draft EIA report. A
public hearing program was conducted at the project site to solicit stakeholder's comments on
the draft EIA report. Public hearing programme was held on Poush 5, 2076 BS at Shree
Bhanubhakta Acharya Secondary School in Galyang Municipality-3, Galyang. There were 686
participants in the programme. Recommendation letters of the project affected municipality/rural
municipality/ward offices was also collected.

Andhikhola Storage HEP (180 MW) Introduction
EIA Report 1-1 NEA-ESSD
1 INTRODUCTION
1.1 Background Andhikhola Storage Hydroelectric Project (AKSHEP) was identified as one of the attractive
projects among the screened and ranked storage projects during the ‘Identification and
Feasibility Study of Storage Projects’ (IFSSP) in 1997. The pre-feasibility level study was
carried out in the fiscal year 1996. The feasibility study of the project has been conducted in
various phases and completed in fiscal year 2075/76 BS. Nepal Electricity Authority (NEA) is
the proponent of the proposed project. Recently, NEA has established Aandhikhola Power
Company Limited as its subsidiary company for development of the proposed AKSHEP.
1.2 Project Proponent NEA is the government owned sole agency responsible for generation, transmission and
distribution of electricity. The Ministry of Energy, Water Resources and Irrigation (MoEWRI) has
granted a survey license on 2074/02/04BS to NEA for feasibility and environmental study. Its
license number is Be.Be.Be. 073/74 Be.Ue.Sa. 821, which was valid up to 2077/02/03 BS. The
survey license is attached in Appendix-A

1.3 Organization Responsible for Conducting EIA NEA, being the project proponent, is responsible to carry out the EIA of the proposed project.
NEA-ESSD has been assigned for the task of conducting Environmental Impact Assessment
(EIA) for the proposed AKSHEP. The Scoping Document (SD) and Terms of Reference (ToR)
of the AKSHEP have been approved by Ministry of Forests and Environment (MoFE) on
2075/10/14 BS (Appendix-H). This EIA document has been prepared as per the prevailing laws
of Nepal as well the approved SD and ToR documents. Moreover, this EIA report was prepared

1.4 Objectives of EIA The main objective of the EIA is to examine the most suitable and cost effective configuration of
the proposed project that would be suitable to the region's environment. In essence, the specific
objectives of this EIA are as follows:
• Identify the project impact area;
• Document the major physical, biological and socio-economic and cultural baseline
conditions;
• Identify potential positive and adverse impacts due to development and operation in
different alternative scenarios;
Andhikhola Storage HEP (180 MW) Introduction
EIA Report 1-2 NEA-ESSD
• Analyze the most critical adverse impacts;
• Examine and select the most optimal alternative from the various relevant options;
• Propose appropriate, practical, cost effective and site specific mitigation measures to
avoid adverse impacts for selected alternative and enhancement measures for positive
impacts;
• Incorporate the input of public opinions in the decision making process related to the
Identification of potential impacts, mitigation measures and project alternatives;
• Outline the elements of environmental mitigation, management, auditing and monitoring
into an Environmental Management Plan (EMP);
• Prepare the comprehensive EMP with mitigation, monitoring and auditing plans; and
• Provide recommendations on the overall feasibility of the project from an Environmental
perspective.
1.5 Rationality for Conducting EIA As per the Environment Protection Rules (EPR), 2054 and the amendment (published in
2065/11/26 BS on Nepal Gazette) made in EPR, 2054, Rule-3, Schedule-2, Clause-F, Sub-
clause 2; for any hydropower generation project of capacity 50 MW or above, an EIA is
mandatory. Since AKSHEP has installed capacity of 180 MW, the project requires an EIA.
Furthermore, as per Rule-3, Schedule-2 Clause-F, Sub-clause 5 of EPR, 2054, any water
resources development activity that displaces more than one hundred people with permanent
residence requires an EIA. As the AKSHEP is assumed to displace over 2,000 people in the
project-affected areas. Similarly, for any projects requiring forest area more than 5 ha, an EIA is
prescribed by EPR, 2054 (Rule-3, Schedule-2, Clause-A, Sub-clause 12). The project will
require about 17.765 ha of forestland for reservoir area, powerhouse, and access road (which
is more than 5 ha). Therefore, the EIA is obligatory for AKSHEP as per prevailing laws. This
EIA requirement is also in accordance with the conditions as recommended by the issued
survey license of the AKSHEP (Appendix-A).
Similarly, As per the Environment Protection Rules (EPR)-2077 Rule-3, Schedule 3 Clause-
“chha”, Sub-Clause 1-ka and 3; and Clause-“ka”, Sub-clause 9, an EIA is mandatory for
AKSHEP.
1.6 Scope of EIA The scope of EIA in terms of project components includes hydroelectric components (dam,
powerhouse and reservoir), access road (7.545 km), project facilities (camps and storage
yards), construction power arrangement, crusher plant installation, quarry activity, etc. The
study of transmission line component and associated substations of AKSHEP is beyond the
scope of this EIA. The environmental study of TL component to evacuate the power generated
from the project to the INPS will be studied under separate license permission.
The scope of EIA in terms of geographical area of AKSHEP covers the administrative and
geographical boundaries of the project influence area (PIA) and project affected district (PAD)
in general (Figure 1-1). In specific terms, the study covers the administrative limits or boundary
of the project affected area (PAA). The PAA includes those Rural Municipalities (RMs) and
Municipality where the project is proposed. The PAA is further divided into direct impact area
(DIA) - the areas to be occupied by the footprints of project structures and indirect impact area
(IIA) referring to the area outside the DIA up to the administrative boundary of RM/Municipality.
Andhikhola Storage HEP (180 MW) Introduction
EIA Report 1-3 NEA-ESSD
The scope of EIA includes the elements of the environment (physical, biological and socio-
economic and cultural). The EIA study has covered the elements of the environment in general
for the PIA and PAD and PAA in detail.

2.5 Project Components The scope of work comprises of preparing the general layout and design of various project
components based on the results of optimization study. Hydraulic design of the individual
structures has been made including the stability checks wherever applicable. The project
consists of headwork (Dam, Spillway, Intake, and Reservoir), headrace tunnel, surge shaft,
pressure tunnel (penstock), powerhouse, tailrace, switchyard, access road, transmission line
etc. The layout of project configuration is presented in figure 2.6
a. Reservoir
The project will required land of 891.105ha in reservoir area including buffer zone dam body
,where as the area of bufferzone is about 139.105 ha. The length of the reservoir is
approximately 21.7 km and its average width is approximately 0.4 km. With the minimum
operating level at EL 623 masl, the reservoir will have a maximum draw down of 77 m.
The dam will create a reservoir with a live storage of 341 million cubic meter. The total and
dead storage capacities of the reservoir are 401 and 60 million cubic meter respectively. Since
the sediment deposition starts from the very beginning of the reservoir, the live storage gets
depleted from the very beginning of project commissioning. The deposition reaches the intake
area only after a very longtime. Thus, the minimum operating level of the reservoir can be
lowered quite considerably once this settlement pattern is known. Based on the 50-year
sediment deposit estimation, the minimum operating level has been proposed at EL 623 masl

Andhikhola Storage HEP (180 MW) Project Description
EIA Report 2-9 NEA-ESSD
b. River Diversion
Andhikhola River has to be diverted completely from the dam construction area to facilitate
construction. For diversion of the river, two cofferdams one at upstream and another at
downstream along with diversion tunnel located at the left bank of the river has been provided.
Both upstream and downstream cofferdams will be the part of the main dam in (Rock fill Dam),
while in CFRD Dam the upstream coffer dam will be isolated approximately 450m upstream
from its toe.
• Diversion Flood
The selection of flood to be diverted during construction primarily depends upon the
construction schedule and the type of dam. For the present case of rockfill dam, it is essential
that the construction pit remains dry in initial phase and later the constructed portion of the dam
never gets overtopped. It is envisaged that the construction of the dam after diverting the river
will take around 4 years. It will take at least two years to sufficiently raise the dam so that any
significant flood has to pass from the diversion tunnel. Construction work may have to be
stopped completely during the rainy season but the river flow cannot be allowed in the
construction area or over the constructed portion. The general practice is to adopt a flood
having return period of 1 in 20 years as the diversion flood. The Kulekhani dam’s diversion
tunnel and coffer dam were designed to pass the 1 in 20 year flood. After careful judgment of
precedence and catchment area and characteristics, a diversion flood having a return period of
1 in 20 years has been selected for the present case having magnitude of 1,124 m3/s.
• Coffer Dam
The downstream coffer dam for Concrit Fase Rockfilled Dam (CFRD) Dam will be also a part of
main dam body as Rock fill dam but the upstream coffer dam will be little bit far from the
upstream toe of dam due to construction of concrete face foundation at toe. As per topography
the upstream coffer dam has been proposed approximately 450m upstream of main dam.
Similarly, the downstream cofferdams have been designed to form a part of the main dam. The
cofferdam is designed to accommodate the design discharge of 1,124 m3/s of return period of
20 years. The height of the coffer dam has been economically optimized simultaneously for the
practical diameter of the diversion tunnel, cost of the diversion tunnel and the cost of the coffer
dam. About 450m upstream from toe of CFRD Dam, a 56 m high cofferdam having crest level
at 612.0 masl and 6.0 m diameter circular shaped two diversion tunnels has been proposed.
The height of coffer dams has been determined to develop a pressurized flow in the diversion
tunnel with sufficient submergence at the diversion tunnel inlet. The length of upstream
cofferdam is about 182 m having crest width of 6 m. The upstream and downstream slope of
the cofferdam are 1:1.5 (V:H) and 1:1.5 (V:H) respectively. The upper stream cofferdam will
have asphalt concrete face with thickness of 0.4m. The purpose of the downstream dam is to
prevent the diverted water flowing back to the construction pit. The height of the downstream
cofferdam is generally determined on the basis of rating curve at that section.
• Diversion Tunnel
Two diversion tunnels have been designed with 1-in 20-year construction flood of 1124 m3/s to
facilitate the construction. The diversion tunnels have finished diameter of 8 m and circular
shaped cross-section have been proposed which will be able to pass the designed flood in
pressurized flow condition. The twin diversion tunnels, namely tunnel-1 and tunnel-2, have
been aligned along the left bank of the river and have lengths of about 1392 m and 1303 m
respectively. Owing to the high velocity of flow, the tunnel will be fully lined with concrete of 50
cm thick. The invert level at the inlet of the diversion tunnel has been provided at 558 masl,
Andhikhola Storage HEP (180 MW) Project Description
EIA Report 2-10 NEA-ESSD
which is about same elevation of the existing riverbed. The invert level at the outlet has been
provided at 548 masl.
At design flow, the velocity is about 11.2 m/s and two diversion tunnels are capable of diverting
1124 m3/s together. However, it has been noted that the design flood is of rare possibility and
may not even happen during the construction period. If the flood comes during construction, the
lining of the diversion tunnel may be damaged due to high velocity. It can be considered
tolerable and can be envisaged that damage would not be irreparable.
c. Dam
The Dam site is located at about 2.5 km upstream of confluence of AndhiKhola and Kaligandaki
River at downhill of Motichaur Village of Syangja District. The riverbed level of this location is
about 543 masl.
Concrete Face Rockfilled Dam (CFRD) has been proposed which envisaged to be an efficient
structure compared with the conventional rockfill dam. The CFRD will have an upstream and
downstream slope of both 1.6H: 1V and will have the height of 167 m for the crest elevation of
710 m. The upstream side will have 1 m thick concrete face while the inner portion will be
selected rockfill. The top width of the dam will be 10 m. Curtain grouting will be provided on the
toe portion of the dam.
d. Spillway
To protect the dam from over topping during the extreme flood condition, a gated spillway is
provided. The spillway is designed for probable maximum flood (PMF) of 4800 m3/s. An ogee
shaped crest type gated spillway with vertical upstream face and a chute with a flip bucket are
provided on the left bank of AndhiKhola on the upstream of the dam axis.
The weir crest level of spillway is kept at El. 685.00 masl and the total width of the spillway
including pier is 98 m. The spillway has four bays each of 10 m clear span and five piers each
of 5 m thickness. The spillway will be equipped with four radial gates each of 10m width and 15
m height. The remaining span of spillway section is kept as free flow spillway (30 m span plus 3
m wall).
The energy of the spillway will be dissipated in a plunge pool of water through a flip bucket
provided at the end of the chute spillway. Two meter thick reinforced concrete slab is provided
on bottom of rectangular chute with sufficient numbers of anchor bolt/dowels along with an
average 1.5 m thick side walls on two sides of spillway chute. Length of chute including flip
bucked is about 350 m.
e. Sloping Intake
Since Andhikhola Storage Hydroelectricity project is a seasonal storage project with 167m high
dam, sloping type intake is proposed which would be useful for a long period even after
sediment deposition. It is located on left bank of AndhiKhola. The intake is designed to draw a
design discharge of 73.0 m3/sec. The dimension of intake opening is selected in such a way
that during driest months when the reservoir level is down to the minimum operating level, MOL
of 623 masl, the velocity of flow through the trash rack does not exceed 0.75 m/sec to draw the
design discharge. A transition is designed at the contraction of waterway keeping the angle of
contraction about 15o. The invert level of intake tunnel at El. 611 masl is set to keep it safe from
the sediment deposit in the reservoir as well as to avoid air entrapment in the waterway when
water level in the reservoir is at minimum operation level. A trash rack and stop log
arrangement are provided at the intake opening to control the entry of floating debris as well as
the suspended particles into the intake. In order to check the flow of water into headrace tunnel
a stop log and two fix wheeled vertical slide gate arrangement are provided in the gate shaft.
The deck level of hoisting platform and the road is kept at El. 710 masl.
Andhikhola Storage HEP (180 MW) Project Description
EIA Report 2-11 NEA-ESSD
There are four intake openings each of 5 m width and 11 m effective height separated by
concrete pier of 1.50 m width. The piers have grooves along its length to slide the trash rack
and stop logs into the position. Discharge through sloping intake opening is conveyed to the
headrace tunnel of diameter 6.4 m through the transition zone of 109.1 m length (considering
15o flaring angle). A vertical gate shaft of internal dimension 7 m x 14 m (W x L) with stop log
and fixed wheeled vertical sliding gate arrangement is provided at the start of the headrace
tunnel. Two no. of air vent pipes has been provided at downstream side of gate shaft.
f. Headrace Tunnel
Headrace tunnel starts from gate shaft of the sloping intake and ends at the Surge shaft. Total
length of the headrace tunnel is about 3112 m. The size of the headrace tunnel is optimized
alone with the size of the Surge shaft. Apart from the basic assumptions, following assumptions
are made for the optimization of headrace tunnel.
• All tunnels are concrete lined.
• Maximum value of manning’s coefficient for concrete line is 0.014.
• Thickness of concrete lining is 50 cm.
A circular shaped 50 cm thick concrete lined pressure tunnel has been proposed as a
conveyance system from the headwork area to 46.8 m downstream of Surge shaft centre,
which includes 23.3m transition to valve chamber. The finished diameter of headrace tunnel is
6.4 m.
Based on the above assumptions, the optimum diameter of the headrace tunnel is estimated to
be 6.4 m. Due to the geotechnical conditions along the headrace tunnel and for the better
hydraulic condition, the headrace tunnel will be fully concrete lined. The thickness of the lining
is estimated to be 50 cm. The design velocity in the tunnel is 2.27 m/s. The excavated diameter
of the circular tunnel is 7.6m. The invert level of headrace tunnel at the starting point is 611.0
masl and that below the Surge shaft orifice is estimated to be 583.1 masl. The average slope in
the headrace tunnel is about 1:550 for first 2524.3 m length, the next 446.1m will have 3%
average slope and the rest length of 141.8m is horizontal including 50 m long rock trap.
g. Surge Shaft
The Surge shaft is placed as far downstream as possible in order to maximize the effectiveness
for controlling surge pressure in the high pressure section of tunnel. The location of the Surge
shaft has been determined to satisfy the following conditions:
• Cross section of the Surge shaft must be a practical diameter to facilitate construction.
• Adequate freeboard should be provided above and below the maximum upsurge and
minimum down surge level and also to suit the topography.
• Free board on Surge shaft is 2 meter.
• Orifice height is 3 meter.
Description of the Structure
Based on the results of the design criteria, restricted orifice surge shaft with 12 m internal
diameter has been provided at the end of the headrace tunnel, at a distance of about 3500 m
from the bulk head shaft of intake. The top elevation of the Surge shaft is at El. 736 masl. The
invert level of the Surge shaft is El. 593 masl. The orifice of Surge shaft has the depth of 5m
and diameter of 5 m. The maximum water level in the surge shaft is estimated to be El. 725
masl and the minimum water level estimated during maximum down surge is El. 627masl.
Maximum down surge level correspond to the full load acceptance from the third unit
immediately after the full load acceptance from the second unit. The total height of the surge

concrete lining.
h. Valve Chamber
Just after surge shaft, a horizontal transition of 14 m is provided where the steel liner starts and
diameter of conduit is reduced from 6.4 m to 4.6 m. After a horizontal stretch of 6 m, a valve
chamber is provided which has a size of 18 m x 8 m x 10 m. The valve will enable dewatering
of the penstock without emptying the headrace tunnel. The valve chamber will be accessible
through 86.0 m long D-shaped tunnel of size 6 m x 6 m which is connected with adit No. 2. The
chamber will have hoist and control unit for the operation of the valve. Air vent shall be provided
just after the valve which will be connected to the top of surge shaft.
i. Drop Shaft

including both bend is estimated to be 227.5 meter and has a diameter of 4.6 m. Entire drop
shaft is concrete lined with a thickness of 50 cm and steel liner of thickness varies from 35 mm
to 63 mm.
j. High pressure Steel Lined Tunnel (Penstock)
The design velocity in the tunnel is about 4.4 m/s for a diameter of 4.6 m. The excavated
diameter of circular tunnel is 6 m including 15 cm shotcrete and 50 cm concrete. The steel liner
has a thickness of 63 mm. Adit 3 located downstream of manifold provides access to the
pressure tunnel. The steel lined tunnel will be trifurcated to feed the three turbines. The
diameter of penstock after trifurcation will be 2 meter. The length of steel line pressure tunnel is
about 1535.9m and the total length of trifurcation is about 113.1m.

EIA Report 2-14 NEA-ESSD
2. Quarries and Barrow Area
The project requires the construction material like stone, aggregate, and sand. These material
will be obtained from nearby available quarry sites. The project has made a quantity survey in
order to find out best possible borrow area. For the construction of dam, rock will be utilized
from rock outcrop at Motichour and tunnel muck. For borrowing sand, river floor on either side
of Andhikhola at Shera, Illunga, Tallo-Galyang and Manke Khola has beed identified. Similarly,
the borrow area for powerhouse has been identified at opposite side of proposed powerhouse
at right bank of Kaligandaki River at Asardi as shown in figure 2-6. Total eight numbers of
borrow areas were investigated and identified in between Ilunga to Tallo Galyangbazar. The
estimated approximate quantity of granular material is 244800 m3, cohesive material is
1730000 m3 and mixed reserve quantity of granular/fines/cohesive material is 940750 m3. The
name of borrow area/test pit and coordinate are presented in table 2-4.

3. Muck/spoil disposal Stock pilling Area
Muck and spoil disposal will be carried out in designated site. Total volume of muck generated
from different component of project is estimated to be about 5.24 MCM. Assuming 25% bulking
factor the total muck generated will be in the range of 6.55 million meter cube. About 3.42
million meter cube of muck will be used in construction of dam and about 3.13 million meter
cube of muck will be manage in different locations. Three different locations have been
identified in the project area to accommodate exceed material. Location of muck disposal and
stockpiling area is given in Table 2.5
4. Bunker and Explosive
The project required the explosive during construction of underground work. Storage and
handling of explosive is risky and needs high-level attention and involvement of security
agencies. The explosive procurement, transportation, storage and use is strictly controlled by
the provisions of the Explosive Act in Nepal. Similarly, Explosive will be procure transported,
stores and used as per the prevailing act provisions in close coordination and consultation with
the concern stakeholder particularly Military and Police Force of Nepal. An explosive bunker
house will be constructed at the project site with facilities for the security personnel in
coordination and consultation with the concerned security personnel of the Government of
Nepal. For such operation army camp with bunker houses is proposed nearby the intake site.
About 2000 ton of Ammonium nitrate is expected to be required as explosive. The total area
allocated for army camp with bunker house is about 2 ha and this area lies within reservoir
boundary during construction period. The camp will be demolish after the completion of project.
The location of Army camp and Bunker is shown in figure 2-6.

5. Construction Equipment and Method of Excavation
Excavation of rock or soil is an important aspect of civil engineering project. Methods of
excavation can be selected according to their purpose that is whether the excavation is for
foundations, slopes, or underground. In broad sense, digging for open foundation and blasting
for underground tunneling methods are common in practice for excavation purpose.
Various mechanical equipment and machines will be used during construction period of project.
The key construction equipment used during the project construction period are Excavator,
Dumper, Jack Hammer, shotcrete Machine, Compressor, Loader, Bull dozer, Crawer Drill,
Batching Plant, Water sprinker, Grout Pump, Dewatering Pump, Aggregate Crushing Plant,
Hydraulic Excavator, Roller, vibarator etc.
6. Crusher Plant and Batching Plant
Project required batching plant and crusher plant to ease the construction activities during
construction period. Provision for batching plants have been made near to the proposed dam
site and right bank of Kaligandaki river opposite to the powerhouse site. As far as possible the
crushing plant and batching plant will be located near the quarry sites. At dam site the location
of batching plant lies within the reservoir boundary area, hence, additional acquisition of land is
not required. Batching plant, which is located opposite to the powerhouse site at right bank of
Kaligandaki, required temporary acquisition of land during construction period. Refer attached
figure 2-6 for proposed location of Crusher plant and Batching plant.

2.6.3 Requirement of Workforce
A large number of workers will be required during the construction phase of the project. The
total workforce including skilled, semi-skilled and unskilled labor during construction period is
estimated to average of 1200 including 50% unskilled, 35% semi-skilled and 15% skilled. The
project has adopted a policy of local employment in the construction jobs. The first priority of
employment opportunities will be given to the affected households of the project affected areas.
2.6.4 Construction Power
Regarding to the construction power, 11 kV substation is proposed near powerhouse, which is
energized from 1km long 11 kV line from tapping point. For the dam site, construction power is
available from proposed 1.6 km long 11 kV line from tapping point. Diesel generator sets are
proposed as backup power to keep aside for emergency use so that the construction works at
the project site will not be affected. The capacity of diesel generator at headwork site, Intake
site, and surge shaft and powerhouse site will be 300 kVA, 150 kVA, 100 kVA and 300 kVA
respectively.
2.6.5 Project Cost
Based on the preliminary design of project components, the cost estimation of project has been
prepared. Total estimated project cost is USD 498.496 Million (Nepalese Rupees 56 Billions).
The project cost might increases due to price escalation in material and other types of costs
that directly and indirectly influence the project construction.
2.7 Reservoir Simulation Reservoir simulation and the estimation of installed capacity as well as the estimation of energy
generation from the project are based on the storage elevation curve of the reservoir area,
minimum operating level based on the dead storage, full supply level, monthly flow of the river,
evaporation, seepage, environmental release and the operation rule of the reservoir.
2.7.1 Base Data for Simulation
Mean monthly inflow and the evaporation from the reservoir surface for different months of the
year used for the simulation are presented in the Table 2.8. Similarly, the Storage-Area-
Elevation Curve is presented in Figure 2.6.

The basic assumptions for the reservoir simulations are as follows:
• The dead storage water level is based on the incoming volume of the sediment
uniformly spread over the reservoir taking a flat horizontal form
• The calculation would start on November 1, when the reservoir is assumed to be full
• The reservoir would attain minimum operating level at the end of dry season if required
and continue to operate at minimum level for some duration at the beginning of the wet
season in order to flush the sediment from live storage area to dead storage area
• Filling of the reservoir would start at the late stage of wet season ensuring that the
reservoir will be full by November 1
• Seepage loss is assumed to be compensated by the minimum downstream release.
Hence, the seepage loss is taken as zero for this simulation
• Dry season energy would be the energy generated from the months November to April
• Wet season energy would be the energy generated from the months May to October
Andhikhola Storage HEP (180 MW) Project Description
EIA Report 2-23 NEA-ESSD
• Maximum water level in the reservoir is 700 masl whereas the minimum operating level
is 623 masl.
• Turbine setting level is 369.3 masl.
• Vertical axis Francis Turbine with overall efficiency of 86.01% will be used to generate
power.
• Downstream release is 10% of the minimum monthly average inflow available.

3 STUDY METHODOLOGY
For the preparation of EIA report, different methods and methodologies were adopted. The
EPR, 2054 and National EIA Guidelines, 2050, mainly guided the methodology. Terms and
conditions received from the then MoFSC were followed during EIA. Literature review, Public
consultation, walkthrough survey, scoping meetings, Geographic Information System (GIS)
analysis were some important tools used for data collection. The different methodologies
adopted for carrying out EIA are discussed in the following sub-sections;
3.1 Desk Study Prior to the mobilization to the project area, desk study of the proposed project was carried out
by reviewing technical feasibility report and survey report of the proposed project prepared by
NEA-PDD. The desk study consisted of review of relevant literature and Legislation.
3.1.1 Literature Review
Pertinent information from different sources was collected and reviewed Literatures collected
and reviewed during the EIA are as listed in bibliography of the report. Mainly the feasibility
report of AKSHEP was reviewed before site mobilization.
3.1.1.1 Physical Environment
The topographic maps published by Department of Survey/GoN were reviewed before site
mobilization (Table 3-1). The project layout was drawn in the map and carried/referred during
the whole site study. These maps were used to figure out inundation area, inundated
HHs/lands/settlement simultaneously using Hand GPS Receivers. Topographical and land use
maps of the area including the Google Earth image were studied for verification.
Data on temperature and precipitation are taken from Department of Hydrology and
Meteorology (DHM). The details of meteorological stations are given in Table 3-2. Information on
geology was derived from the updated feasibility report of AKSHEP. Review of topographical
map and land use map was done to identify the land use patterns of the area. The details of
different topographical maps used during the study period are given in following Table 3-1.

3.1.1.2 Biological Environment
Publications of Division Forest Office (DFO) of Syangja and Palpa districts were reviewed to
collect general information of forest area, types and management. Information on biodiversity of
project impact area was collected from the field visit and FGD. Different literature on birds and
mammals, as listed in Bibliography, were reviewed.
3.1.1.3 Socio-economic and Cultural Environment
The major reports and publications consulted include District profiles of Syangja and Palpa
published by the District Development Committees; National Population and Housing Census
(2011) published by Central Bureau of Statistics (CBS). Socio-economic and cultural data, such
as population of project affected districts (PADs) and Municipality and RMs, households’ size,
male-female ratio, infrastructures, ethnicity, religion, etc. were derived from CBS publications.
3.1.2 Legislation Review
During the Scoping Phase, related legislations and policies were reviewed. Environment
Protection Act, 2053 (1997); Water Resources Act, 2049 (1992); Electricity Act, 2049 (1992);
National Park and Wildlife Conservation Act, 2029 (1973), EPR, 2054 (1997); Electricity Rules,
2050 (1993); Forest Regulation, 2051 (1995), Water Resources Rules, 2050 (1993) and
Hydropower Development Policy, 2058 (2001) are some major legislation reviewed.
3.2 Delineation of Project Impact Area Rule 4 of EPR, 2054 (1997) apparently defines project impact area as administrative
geographical boundaries such as district and Village Development Committee (VDC), currently
RM/Municipality, where the project is proposed for development. A district is a larger
administrative unit comprising of a number of local administrative units called RMs and
Municipalities. Based on the magnitude of the predicted impacts, the project impact area is
divided into following two categories.
3.2.1 Project Affected District
The district where the project is being implemented or which is directly affected by the project
construction activities is termed as PAD. As per the definition, Syangja and Palpa are the PADs
for the proposed AKSHEP. However, the envisaged environmental impacts within the
geographical jurisdiction vary greatly as some geographical area receive higher impact, some
lower while other areas get no impact at all.
3.2.2 Project Affected Municipality/RM
Project Affected Municipality/RM is the Municipality/RM, where the project is going to be
developed. For the proposed AKSHEP, Waling and Galyang are the project affected
Municipality, whereas Kaligandaki and Rambha are the project affected RMs respectively. In
general, these administrative units are referred as the PAA in the report. The PAA is further
divided into following two types;
3.2.2.1 Direct Impact Area (DIA)
The National EIA Guidelines, 1993 defines the direct impact as a direct alteration in the exiting
environmental conditions as consequences of project activities. These are the core areas
where construction and operation activities are carried out and will be impacted directly by the
project. In this area, environmental components shall be directly affected by the project
footprints. DIA encompasses the locations that will hold major project components like
headwork, reservoir area, conveyance systems, powerhouse, quarry sites, muck disposal sites,
dewatered zone and project access roads. Thus, the settlement area, forests or other
vegetation and places having built-up infrastructures or facilities that fall within the core area
Andhikhola Storage HEP (180MW) Study Methodology
EIA Report 3-3 NEA-ESSD
constitute the DIA of the project. Based on spatial coverage, this area is also termed as High
Impact Area.
Headworks Area: Headwork comprises of concrete face rock filled dam, spillway provision,
intake, campsite, muck disposal site, quarry site, etc. the area occupied by all the above-
mentioned features of headwork is considered as DIA.
Reservoir Area: Due to obstruction created by dam, inundated area behind it is 21.7 km
upstream. The area occupied by reservoir and dam with consideration of safety factor is about
891.105 ha and it is considered as DIA.
Water Conveyance System: It consists of underground components such as headrace tunnel,
penstock, vertical shaft and penstock, etc. The DIA depends on the overburden height and type
of rock above it. Preliminarily, it has been considered as 150 m of buffer area from centerline of
the component on each side as DIA of the system.
Surge Shaft Area: Restricted orifice open type surge shaft with 12 m internal diameter has
been proposed. The outer diameter of shaft plus slope cutting distance, leveling and finishing of
open area is considered as DIA.
Powerhouse Area: Semi-surface powerhouse area plus buffer distance of 150 m on all side is
considered as DIA.
Dewatered Zone: The stretch of the Andhikhola extending from the Dam site up to its
confluence with the Kaligandaki River, which will be affected due to reduced flow (dewatered
zone), is considered as DIA.
Water Augmented Zone: The stretch of the Kaligandaki River extending from the powerhouse
site up to its confluence with the Saptagandaki River which will be affected due to increase in
flow (augmented flow zone) is regarded as DIA.
Access Road: About 7.545 km of access road is proposed by the project. DIA of road depends
on the topography, slope cutting and its width. Preliminarily, 10m width for whole stretch of road
as per topography of the area is considered as DIA.
Tailrace Site: The tailrace tunnel starts from the outlet gate of powerhouse. Length of the
tailrace is 72m. DIA is considered as buffer area of 150 m on both side from the centerline of
tailrace.
Other: The supplementary features such as quarry site, muck disposal site, bunker area, camp
area and stock piling area near tailrace also affect the occupied land. The area occupied by it is
considered as DIA.
3.2.2.2 Indirect Impact Area (IIA)
These areas lie outside the DIA and receive impact indirectly by the induced and allied activities
of the project. The geographical areas outside the DIA up to the boundary of the
RM/Municipality are termed as Indirectly Impacted Area (IIA) of the project. It is expected that
activities of project construction and workers, increased supply of the goods and services may
further affect the surrounding villages of DIA. This area is also termed as Moderate Impact
Area.The term “project” indicates the AKSHEP and “Area” refers to the DIA and IIA. The term
“project area” is also referred to as the study area for the Scoping/EIA.
3.2.3 Identification of Project Affected Families
Families residing in the core project area or surrounding area whose land, house/shed,
property, access to assets, and income sources or means of livelihood may be affected due to
Andhikhola Storage HEP (180MW) Study Methodology
EIA Report 3-4 NEA-ESSD
project construction or operation are considered as ‘Project Affected Families’ (PAF) and the
members of these families are referred to as ‘Project Affected Persons’. These are further
categorized as:
3.2.3.1 Project Affected Families (PAFs)
The households losing up to 10% of their total land are categorized under this category.
3.2.3.2 Severely Project Affected Families (SPAFs)
In accordance with current practices and guidelines, families who are physically displaced from
their residences or commercial establishments and those who are severely affected through
loss of agricultural land are classified as SPAF. This includes two sub-categories: i) Households
losing land more than 10% upto 50% of their land and ii) Households losing more than 50% of
their land. The households losing residential structures are also included in this category.
3.2.3.3 Vulnerable Communities
In the context of Nepal, vulnerable community means communities who are commonly landless
and marginal farmers living below subsistence level. Moreover, these groups have no or limited
access to public resources and they almost never participate in national planning, policy, and
don’t have access in decision making process or in development initiatives. As a result, their
risk of falling below the poverty line is high.
Formal and informal studies conducted in Nepal reveal that most of Janajati, Adibasi and Dalits
fall under the category of vulnerable person in Nepal. Women, disabled, ethnic minorities and
Dalits groups as the predominant poor and marginalized groups fall under vulnerable
community. Women in all social groups and regions are more disadvantaged than their male
counterpart and even among women, widows, separated and women headed households are
particularly disadvantaged.

(Ni), Sodium (Na), Potassium (K), Chromium (Cr). Total Coliform /E. coli as per Standard
Methods.
Chlorides, hardness, alkalinity were analysed by titration method whereas Ammonia, Nitrate,
Nitrite, Fluoride, Phosphates, etc. were analysed by using UV Visible spectrophotometer (UV
VIS) applying as digestion required. Turbidity was tested using Nephelo meter and Total
Suspended Solids, Total Dissolved Solids were estimated by gravimetric method.
Similarly, Metal (Iron, Manganese, Lead, Sodium, Potassium, Chromium, Zinc, Lead,
Cadmium, Nickel) samples were analysed by Atomic Absorption Spectrophotometer (AAS) and
Mercury will be analysed by AAS with Cold Hydride Vapour Generation System whereas
Arsenic by AAS hot vapour hydride generation system. The BOD analysis was conducted by 5
days incubation method whereas COD shall be analysed by open reflux method.
3.3.1.2 Air Quality
For the determination of TSPM, PM10, PM2.5 and Lead; sampling were done with help of high
volume sampler (HVS). Pre-weighted fiber glass filter paper were used for the collection of
PM10, PM2.5 and pre-weighted cup were used for larger particles than PM10, PM2.5. After
sampling safely transported to laboratory and taken the weight of exposed filter paper and cup
and finally determine the PM10 and TSPM against the drawn volume of air.
For determination of lead, exposed filter paper was digested in Nitric Acid and the lead
concentration determined in Atomic Absorption Spectrophotometer (AAS). Similarly, SOx and
NOx were sampled simultaneously by the same instrument through the attached gas sampling
gadget. Sodium Hydroxide and Tetra Chloro Mercurate (TCM) solutions absorbing reagents
were used for NOx and SOx respectively. The collection tubes were kept chilled with ice water to
prevent evaporation and to provide greater absorption. Samples were instantly stored in

a. Quadrate Sampling
Division and Sub-division forest office of Syangja were consulted regarding the forest
inventories methodology for reservoir and access road. Taking into account the site
accessibility and coverage, quadrant sampling was done in the reservoir area to assess CFs
and GMFs. During the Quadrant Sampling, DBH and height of all tree and pole was measured
and noted. Any new species of tree found outside the quadrant was also noted.
Following the methodology as defined in Community Forest Resource Inventory (CFRI) 2061
(Table 3-5), concentric circular plot of radii 1.78 m, 2.82 m, 5.64 m and 12.61 m were used for
the four vegetation subplots consisting of seedling, sapling, pole and tree respectively.
Altogether, 13 sample plots were surveyed in the CFs and GMF, as very small patches of CFs
and GMFs fall within the reservoir area. This represents the 3.37% of total forest area (0.6 ha
out of 17.765 ha). The ground vegetation and any new species of tree sighted outside the
sample plot were also noted. Based on this information, loss of regeneration (saplings and
seedlings), loss of vegetation (pole and tree class), is calculated.

In each plot, tree species were identified, and all trees equals or exceeding a diameter of 10 cm
at breast height were counted with their height and DBH. Seedlings and saplings were
identified and noted. Similarly, occurrence and distribution pattern of shrubs and herbs species
available in and around the sample plots were recorded. Additional information on herbs and
shrubs was collected from the field observation, literatures and Focus Group Discussion (FGD)
using biological questionnaire. The list of participants of FGD is attached in Appendix C.
In addition, trees on private unarable land (Kharbari) within the reservoir areas were estimated
through quadrate sampling. A circular plot of 12.61 m radius was laid and all the trees within the
plot was noted. Likewise, private trees on access road was assess through total enumeration.
For private trees (including fruit, fodder and other trees) on agriculture land, census was carried
out for every household of the reservoir area and other project components of the proposed
AKSHEP administering social HHs questionnaire. All private trees potentially impacted by the
project were noted in the questionnaire.The following table summarizes different methods used
to collect baseline information on the biological environment.

b) Key Informant Interview (KII)
For this EIA of the AKSHEP, altogether three KIIs were carried out in order to obtain the
relevant data on the biological environment. The officers of the Division and Sub-division forest
office and local were consulted to collect information on forest and wildlife as well as local use
of the forest resources.
c) Focus Group Discussion (FGD)
Altogether three Focus Group Discussion (FGD) were carried out with the project affected
community forest users groups (CFUGs) and local people. During the meetings, participants
were introduced about the project features, potential impact on the environment, various
mitigation and enhancement measures likely to be adopted during construction and operation
phase of the project.
A checklist was developed and introduced in the field to collect the primary information about
dependency of local people on community forest and non-timber forest products. The issues
raised during meetings were discussed and recorded. FGDs were held to collect information on
the availability of flora and fauna, dependency of local people on forest resources, availability of
Non-Timber Forest Products (NTFPs), etc. The attendance of participants of the FGD is given
in Appendix C.
3.3.2.2 Wildlife
Data on wildlife was collected by direct observation at different project sites and adjacent areas
with various land use types (e.g. forest areas, agriculture land, etc.). The indirect evidences
such as scats/droppings, calls and cliffs were also used for identification of mammals and birds
in the area. Evidences of occurrence of wildlife were also collected through questionnaire
survey. Records of DFO were also used as a background information.

3.4 Assessment of Fish and Aquatic Life For the environmental assessment of the AKSHEP, the study of the fisheries and aquatic life is
an important aspect. So, in order to acquire information about the fisheries and aquatic life of
the Andhikhola and Kaligandaki River, an initial and rapid assessment of fisheries was carried
out during the scoping phase of AKSHEP. This assessment assessed the fish habitat and fish
bio-diversity of the river system.
The study methodology for fish and aquatic life includes the literature review, field survey, data
collection ,data analysis and study of fish bio-diversity by the expert and technicians. The study
team has carried out walk through survey along the bank of river, fish and plankton sampling,
observation of local catch by local fisherman, data collection and data analysis.
3.4.1 Literature Review
The existing literature, reports and published documents on fish and fisheries as well as EIA
reports (fisheries section) of other related hydropower projects were reviewed. The review was
mainly focused on operation phase environmental monitoring report of Kaligandaki 'A'
Hydropower Project. The review aims to understand the fish diversity of different river system of
Nepal, particularly on fish and aquatic life of Andhikhola River.
3.4.2 Sampling Locations
In developing hydroelectricity projects, the environmental conditions of the river and the riverine
system seem to change a lot mainly in the intake site or upstream of dam, dewatered zone and
the tailrace region.
Five sample site locations along the Aandhi Khola stretch as required for the Aandhi Khola
Storage HEP. Fish samples were collected from up and downstream of Dam site and Reservoir
area also include of Aadhi Khola and Kaligandaki River to collect information about fish
distribution and composition of the river.
The proposed powerhouse site area at the left bank of Kaligandaki River was sampled to
understand the fish diversity and migration pattern. Approximately 2000 meter area was
covered at each sampling site.
The planktons and aquatic insects were collected from station FAK1, FAK2, FAK4 and FAK5.
The sampling stations are set along the different stretch of Aandhi Khola and Kaligandaki River.
Cast net and Gill net were used for fish catch for sampling and local fishermen were hired to
carry out the cast net operation on sampling sites. The sampling stations are given in the table
below;

aquatic life of river system in the project area. The field survey and investigation lasted for 17
days (August 18, 2017 to September 3, 2017) in the wet season during scoping phase.
Similarly, the field survey lasted for 12 days (April 8 to April 19, 2019) in the dry season during
the EIA phase.
The field survey included collection of fish specimen, planktons and aquatic insects from
different sampling locations, identification and characterization of fish habitat and collection of
information about fish migration and spawning pattern. Checklist was developed and used for
the fish data collection
Picture 3-3: Fish and Aquatic Life Survey Team (Wet and Dry Season)
3.4.3.1 Habitat Characteristics
The fish habitat was studied by using visual method (observation). Topographical map of
1:25000 scale was used for river habitat identification and characterization. Possible spawning
habitat conditions such as type, cover and shelter were recorded by walking along side of river
bank. The fish habitat such as run, riffle and pool in different section of Andhikhola and
Kaligandaki river were recorded by visual observation during the field visit.
3.4.3.2 Fish Specimen Collection and Catch Study
Standard data sheet were developed and used for data collection. The number of efforts
employed by fishermen was recorded to determine Catch per Unit Effort (CPUE). Fish species
caught during the field visit at each sampling sites will be identified using standard method of
taxonomy (Shrestha, 1981 and 1994). Measurements of total length, weight and other
morphological characteristics of collected fish were recorded. Photographs of collected species
were also taken. After collecting the required data, the caught fish species were released in
River.

3.5 Data Analysis The data (primary and secondary) collected was analyzed qualitatively and quantitatively as
appropriate. The following methods were used to analyze data of three different environments;
3.5.1 Physical Environment
The type of land use and area calculation has been prepared with reference to the
topographical maps, cadastral map, survey report, digital maps provided by the Department of
Survey with field verifications. Similarly, the numbers of structures in reservoir area were
determined with the help of the plan and profile of the Final Survey Report with verifications at
site. Each structure within the reservoir was individually marked on the GPS and the
dimensions of the structure were measured/noted.
The collected data from the field visit was analyzed using different software like ArcGIS 10.2.1,
AutoCAD, Google Earth, MS Office by the study team in coordination with the project engineers
and experts. Necessary maps and information thus generated were presented in the report.
The beneficial and adverse impacts have been predicted and appropriate mitigation measures
are proposed to reduce the adverse impacts.
3.5.2 Biological Environment
The data from forest sampling were quantitatively analyzed for density, basal area, crown
coverage and wood volume. These parameters were calculated using the following formulae:
No. of individuals of a species
Density (D)/hectare = ---------------------------------------------------------- 10,000
Size of the plot Total no. of plots sampled Density of individual species
Relative Density (RD) = ------------------------------------- 100 Density of all species Total no. of plots in which the sp. occurred
Frequency (F) % = ------------------------------------------------------- 100 Total no. of plots sampled
Andhikhola Storage HEP (180 MW) Study Methodology
EIA Report 3-19 NEA-ESSD
Frequency of individual species
Relative Frequency (RF) = ------------------------------------------ 100 Frequency of all species Total basal area of particular species
Relative dominance (Rdom) = ------------------------------------------------ 100 Total basal area of all species
Basal Area is the trunk cross-sectional area. For estimating the basal area, wood volume and biomass of the pole size and timber size trees to be felled for the project, the trees were individually enumerated and identified with their local names and botanical nomenclatures. Then their diameter at the breast height was taken in each sampling sites. Similarly, the "Volume of forest trees of Nepal" was referred to estimate the volume up to 10 cm top diameter with bark. The basal area of each of trees was calculated based on diameter at breast height.
Basal Area (BA) = (dbh/2)2
Importance Value Index (IVI) = RD + RF + RDom
Wood volume of standing tree = 1/2 BA Height
Likewise, data from forest census survey was quantitatively analyzed for each individual tree/
pole for its biomass.
The average density of the basal area per hectare was calculated as total basal area (m2)
divided by total area of land (ha). For determining the wood volume, basal area x height formula
was used. Moreover, loss of forest land, loss of forest species, its type, volume and number of
trees to be cut etc. were identified and calculated.
Information of flora and fauna (plants, mammals, reptiles, avifauna, herpeto-fauna etc.)
collected from the field was listed. Nationally protected species, CITES listed species and IUCN
Red list was identified by cross checking the respective list of flora and fauna. In addition,
nationally banned flora species for collection, felling, transportation and export was also
reviewed.
In addition to the above, the cost benefit analysis of the project was done as per the conditions
prescribed in consent letter of the then MoFE (Appendix I of the ToR document). Such
environmental cost-benefit analysis was done by considering the following environmental cost
and benefits in addition to the conventional valuation.
3.5.3 Socio-economic and Cultural Environment
The collected information and data were analyzed qualitatively and quantitatively to establish
baseline information on physical, biological and socio-economic and cultural environments. For
this purpose, all checklists, questionnaires and field notes were thoroughly reviewed, cleaned,
edited and coded. Then this data/information from the questionnaires/checklists was entered on
processing data entry layout. Then using simple statistical tools quantitative data such as
mean, range, and percentage were computed. The descriptive method was used for the
analysis of qualitative data.
The MS Office (WORD and EXCEL) software program was used further analysis. The outputs
of such analysis were then analyzed and converted in the context of the study objectives. The
secondary and primary information and data collected were cross-checked and triangulated.
Based on the findings of the baseline information and data potential impacts on socioeconomic
and cultural environmental impacts were identified and assessed. Based on suggestions made
Andhikhola Storage HEP (180 MW) Study Methodology
EIA Report 3-20 NEA-ESSD
by the local people and stakeholders' enhancement measures for beneficial impacts and
mitigation measures for adverse impacts are proposed.
Review of concerned laws, rules and regulations and outcome of the public consultations, and
literature reviews are other important tools that were used to analyse the data. The analyzed
data were then interpreted and discussed in appropriate sections of the EIA report.
3.6 Public Involvement/ Consultation
3.6.1 Consultation during EIA
In August-September, 2019, as part of the EIA fieldwork, extensive consultation was made with
the stakeholders by the study team. This included in-depth interviews with key stakeholders in
the project area, market surveys and informal meetings with local and district-level stakeholders
(FUGs, GoN line agencies, etc.). The main issues and concerns of the stakeholders have been
incorporated in the public involvement/consultation chapter (Chapter 10) of this report.
3.6.2 Public Hearing

newspaper. The programs were also be broadcasted through local FM radio station. Request
letters for participation in the public hearing were sent to concerned ministries and departments
and receipt of the notice receive also collected. The notices were displayed at district level
offices, RM/Municipality office and at public places of the major settlement of project
RMs/Municipality. Video record was made for the entire program and written concerns of the
participants were collected. The recommendation letters of affected RMs/Municipality were
collected. The detail of public hearing is presented in Chapter 10.
3.7 Impact Identification, Prediction and Evaluation
3.7.1 Impact Identification
Based on consultations organized among affected people and stakeholders during preliminary
field visit made by the study team for Scoping Document preparation, impacts/issues that may
trigger due to project intervention were identified and prioritized. From the scoping exercise
both types of beneficial and adverse impacts were identified for EIA. The impacts were
categorized as per environmental domain (i.e. physical, biological, and socio-economic cultural
environments). Likewise, an impact that may trigger under different phases of project
implementation (i.e. pre-construction, construction and operation) was also taken into account
for the assessment. During EIA phase, following tools were used for impact identification:
• Checklist, Key Informant Interview
• HHs Questionnaire
• Table format for loss of land, crop production and property of the PAFs/SPAFs
• Expert’s judgment
3.7.2 Impact Prediction
Topographic map of the impact area been used in predicting the impacts of the proposed
AKSHEP by analyzing the effect of project activities on the resources like existing
infrastructures, rivers/rivulets, settlements, private land, forest, etc. present in the location. GIS
analysis was also used. The expert’s judgment using past experiences of similar type of
projects have been used to predict impacts. Wherever possible, impact predictions have been
done quantitatively.

3.7.3 Impact Assessment/Evaluation
The assessment of impacts is based on the baseline environmental conditions of the affected
area with the project activities in relation to spatial and temporal aspects in terms of magnitude,
extent and duration using various environmental prediction methods. The impact has been
predicted over a specified period and within defined area. Consequences of environmental
impacts were interpreted in terms of local, regional and national contexts. The significant
positive and adverse environmental impacts associated with the project components have been
identified considering the impact zone. The magnitude, extent and duration of the impacts
which were categorized according to the National EIA Guidelines, 1993 are given below:
3.7.3.1 Magnitude of Impact
The following criteria were considered in this EIA to evaluate the significance of the identified
and predicted adverse impacts of the project activities on the environment.
• Low Impact (L): If the value of the resources could be used with no or minimum
inconvenience to the public
• Medium/Moderate Impact (M): If the value of the resources could be used with
inconvenience to the public
• High Impact (H): If the value of the resources reduced far below publicly acceptable level.
The magnitude of impact is considered serious or high/major if a major adverse impacts
cannot be mitigated.
3.7.3.2 Extent of Impact
• Site Specific (S): If the impact is limited up to the project site/area is site specific.
• Local (L): If the impact is limited up to the affected RM/municipality or the watershed alone
then it is termed as local.
• Regional (R): If the impact of the work extends beyond the watershed or to the entire
district or further then it is termed regional.
3.7.3.3 Duration of Impact
• Short Term (ST): If the impacts last only for 3 years after project initiation it is classified as
short term. Construction phase impacts are mostly categorized under this category.
• Medium Term (MT): An impact that continues for more than 3 years but less than 20 years
is considered as medium-term. The construction phase impacts which carry over for few
years of operation falls under this category.
• Long Term (LT): An impact that lasts beyond 20 years is considered long term. The
operation phase impacts are mostly categorized under this category.
Based upon the above classification a numerical scale is developed in order to provide a
qualitative assessment of various types of predicted impacts. The following ranking
methodology has been used in this EIA (using the National EIA Guidelines, 2049 (1993).
Magnitude (M) Value Extent (E) Value Duration (Du) Value
High/Major 60 Regional 60 Long Term 20
Moderate 20 Local 20 Medium Term 10
Minor/Low 10 Site Specific 10 Short Term 05
The sum of impact values provides a maximum of 140 and minimum of 25. For any impact
whose sum of impact value is more than 75, the impact is considered as ‘Highly Significant’.
For the sum of impact value between 50 and 75, the impact is considered as ‘Significant’.
Similarly, the impact is considered as ‘Less Significant’ if the sum of impact value is below 50.
Andhikhola Storage HEP (180 MW) Study Methodology
EIA Report 3-22 NEA-ESSD
3.8 Limitations of the Study The assessment of the site conditions was based mainly upon visual observations, literature
and interviews with the local people. Since no updated topographic maps are available, the GIS
analysis was based such maps mainly of mid-1990s. The generated information from GIS,
mainly land use, does not coincide with the actual field data. Field verifications are done to
minimize the error but still some conflicts are encountered in mapping. The lack of detail survey
report of the reservoir area created some difficulties in assessing the impact of the project
during the field study. For defining the reservoir area, the level of full supply and freeboard was
fixed by using GPS only. Some information, particularly on physical and biological environment,
reflects the characteristic only of that particular season and time of investigation. This resulted
in generalization of impacts for project and other facilities.
Difficulties were also encountered during the socio-economic data collection as some of the
land/structure owners of the affected area were absent during the HH survey. Furthermore,
some information mainly on land holding, agricultural production, income and expenditure are
approximate value based on the HH survey. Problems were encountered in determining the
owner of the land and assets as the legal transfer of land ownership was not done for
generation in cases of some households.

4.1.4 Geomorphology and Geology
The proposed project lies in the Midlands of the Lesser Himalaya. The Lesser Himalaya is
made up of highly deformed, thick piles of elastic and carbonate rocks. Two major tectonic
features bound it. The Main Boundary Thrust (about 20 km) along the margin (south) and Main
Central Thrust (about 70 km) in the north of the project site. The project components lie within
Galyang formation, Lakharpata formation and Syangja formation as shown in figure 4-12. The
predominant rock types are gray and light gray slate and shale, carbonaceous slate, gray
dolomite, variegated phyllite and quartzite. Engineering geological map prepared by project is
attached in Appendix-B.
According to regional geological map prepared by Department of Mines and Geology (DMG) in
1987, Galyang formation consists of dark grey shales with black limestones thin calcareous
slate and grey dolomitic limestones, black carbonaceous slates with thin calcareous sandstone
beds, grey to black dolomitic limestones. Syangja formation consists of white milky white, pale
orange, pinkish, or purplish calcareous quartzites and quartzitic limestones with dark grey and
purple shales pinkish calcareous quarzitic beds, grey arkosic sandstones, dark grey and pale
green shales. The geology and geomorphology of the project area is disussed in the following
subsections.

4.1.4.1 Geology of Project Components
a) Reservoir Area
The reservoir area lies within the Galyang Formation, Lakharpata Formation and Syangja
Formation. The predominant rock types are gray and light gray slate and shale, carbonaceours
slate, gray dolomite, variegated phyllite and quartzite. Three formations (litho-units) were
identified within reservoir area, which is described separately here underneath (Source:
Feasibility Study Report of AKSHEP, 2019).
• Gray and light gray slate and shale and carbonaceous slate
This rock unit is mainly exposed at the moderate slope of the dam axis, intake, tunnel
alignment, powerhouse, and most of the reservoir area (from dam axis to the Karadi Khola).
This unit is mainly composed of gray and light gray slate and shale, carbonaceous slate and
inters banding of slate and carbonate bands (gray dolomite). Along the upstream of the Andhi
Khola, from the dam axis to intake thinly bedded dark gray to black slate inter banding with gray
coloured dolomite is dominant. Gray to light gray colored, thinly bedded, fine grained, slate and
shale is dominant along tunnel alignment, surge shaft and penstock alignment (at Guthi
Bhanjyan, Chandanbari Barandada and Blpuk area). This rock unit shows typical weathering
color of light red to light yellow. Weathering is relatively high along tunnel alignment, surge shaft
and penstock alignment than headwork area. Red colored residual soil is common along the
tunnel and the penstock alignment. Regionally the rock exposures dip towards south. However,
the north dipping foliations are also common due to the presence of local fold.
• Dolomite Unit
Dolomite is exposed in the steep peaks and ridges of Nibuwa Kharka along the right bank of
the Andhi Khola (River). This rock unit crosses the Andhi Khola forming narrow valley between
the Karadi Khola and the Chiuri Village section. Lithology of this unit mainly consist of thick to
Andhikhola Storage HEP (180MW) Existing Environmental Condition
EIA Report 4-15 NEA-ESSD
massive, gray to white coloured, jointed dolomite with thinly laminated slate. The attitude of the
foliation plane near the Karadi Khola is 1650/750, similarly near the Churi is 2150/120. The
outcrop of dolomite is fresh to weathered, medium to strong in nature.
• Red purple Phyllite and pink Quartzite unit
This unit is exposed near the Mohoriya village (South of Waling), upper reaches of the
reservoir. Similarly, same rock type is also exposed along road section of Siddhartha Highway
about 500 m towards the Ramdi Bridge from the Malunga village. Lithology consists of light
gray to white, and pink coloured, medium to thick bedded, medium to coarsed - grained
quartzite is inter-banding with red purple slate and phyllite. The dip direction of this rock unit
varies from 1900 to 2100 with dip amount 600- 700.
b) Dam Site
The dam site is located about 2.5km from Andhimuhan (local market) and this location is more
or less symmetrical river valley of Andhikhola. Geomorphologically, the right bank at the dam
site is about 48° and the left bank is 50° slope. The dam axis at the riverbed comprises large
boulders of conglomerate. No bedrock is exposed at the surface but the bedrock is expected at
few meters depth from the surface. The right bank in this area is composed of conglomerate
whereas the upper section on the right bank is composed of dolomite. The left bank of the dam
site comprises thin overburden of conglomerate and colluviums underlain by bedrock of slate.
At damsite area, Andhikhola flows through the contact zone of dolomite and slate. The river
demarcates the lithological differences between dolomite and slate. Dolomite at the right bank
seems to be highly fractured at the surface. Hence, a landslide has been seen near to the dam
site area. The slate bedrock at the left bank is also found to be highly weathered and weak in
nature.
c) Intake Site
The intake site proposed on the left bank of Andhikhola. Rock is exposed from river level up to
El. 640 m. Rock is fresh to slightly weathered, grayish black, thinly bedded, and fractured to
blocky phyllite. The attitude of foliation planes varies from N36oW- N55oW and 21o-46o W strike
and dip respectively. Joint planes are rough and irregular. The maximum crown face over break
expected at this site is about 10 m. The portal face site is almost perpendicular to strike so that
it is favorable for portal site.
d) Headrace Tunnel
It is located on the left bank of Andhikhola passing through steep topography and crosses the
ridge at an elevation around 1000m where the rock cover of the tunnel is estimated around
350m. The topography of tunnel alignment approaching surge shaft is moderately inclined. No
major instability extending to the tunnel level was encountered. The headrace tunnel will cross
the Andhikhola formation, which is more than 900 m thick consisting of upper member of grey
slates with calcareous band black carboniferous lamina. The lower member consists of black
carboniferous slates with several bands of limestone and dolomitic sand stones (After Sakai, H.
1986). The multiple springs, which are observed along the slopes, reveal that the groundwater
table is relatively high.
e) Surge Shaft
Surge shaft has been proposed near to Zero Kilo. The bedrock exposed near to the road
section comprises fractured, moderately weathered bedrock of slaty phyllite. Few bands of
thick phyllite has also been observed within this location.
Andhikhola Storage HEP (180MW) Existing Environmental Condition
EIA Report 4-16 NEA-ESSD
f) Penstock Alignment
The rock expected along the penstock alignment is thinly bedded phyllite. The general attitude
along the alignment is N18oW and 20o dip. The rock exposure along the route is scattered and
most of the area is covered with residual soil and partly with colluviums. The thickness of
residual soil as well as colluviums varies from place to place.
g) Powerhouse and Tailrace
The powerhouse is a semi surface type located on the left bank of Kaligandaki River and will be
founded on phyllite. Two boreholes were drilled at the powerhouse and tailrace alignment sites.
The phyllite along left bank of Kaligandaki River is massive to blocky and partly fractured. Two
sets of joints are measured. The joint planes are rough, irregular and slightly altered. The depth
of overburden at the hill side edge of terrace just below the hill slope is about 13m. The terrace
deposit is composed of cohesion less, semi consolidated and rounded to sub rounded boulders
of quartzite and gneiss mixed with sandy and silty matrix.
h) Access Road
The proposed 7.545 km access road lies on Galyang formation which consists of dark grey
shale with black limestone thin calcareous slate and grey dolomitic limestone, black
carbonaceous slates with thin calcareous sandstone beds, grey to black dolomitic limestone.
4.1.4.2 Soil Types of Project Area
a) Residual Soil
Most of the residual soil is developed at the top of the flat river terraces. In some part of the
project area, the residual soil overlies the highly weathered rock present along headrace tunnel
and penstock alignment, surge tank and powerhouse site. The thickness of residual soil
developed varies from 5 m to 25 m. The sub-tropical climatic conditions intensify the
development of residual soil in the project area.
b) Terrace Deposits
Alluvial River terrace deposits are well developed between the Illunga villages to the Karadi
Khola. Similarly, terraces are also present in the upper reaches of reservoir between the
section Churi and the Walling along the banks of Andhikhola. These deposits composed of
partly compacted to loose, sub angular to rounded gravel and boulder metasandstone,
quartzite, dolomite, mixed with silty, sandy and calcareous matrix.
c) Colluvium Soil
The colluvium deposit is present on moderate to steep slopes on the both banks of Andhikhola.
The colluvium deposit is composed of boulder mixed soil. The main constituents of the
colluvium deposit are angular to sub angular fragments of slate, dolomite, quartzite, phyllite and
shale in silty and clayey matrix. The thickness varies from less than 1m to 5m or more from
place to place depending on the topography of the area.
d) Recent River Deposits
These deposits are found along Andhikhola and are composed of sub rounded to rounded
fragments to boulders of metasandstone, quartzitic dolomite, phyllite, slate, shale etc. and
associated with sandy, silty materials and almost clean pebbly sand.
4.1.4.3 Geomorphology of Reservoir Area
Andhikhola River flows east to west in the wide V-shaped valley within the project area. The
river gradient is medium to low in the project area. In some part such as downstream of the
Chiuri, the river passes through narrow valley forming gorge. Both North and South faces
slopes are generally covered by colluvium deposits and alluvial terrace, which are mostly
cultivated. Bed rocks are exposed only in the narrow section of the valley. Many tributaries of
Andhikhola Storage HEP (180MW) Existing Environmental Condition
EIA Report 4-17 NEA-ESSD
Andhikhola are more or less perpendicular to it and form alluvial fans. These tributaries are
deeply incised and have parallel to sub-parallel drainage patterns. The river shows distinct cut
bank (erosional) and depositional bank within the project area.
Local people use the alluvial terraces along the depositional bank of the Andhikhola for
cultivation. Besides the river terraces, the alluvial deposits are found as the alluvial fans. The
colluvial deposit is found on the hill slopes on both banks of the Andhikhola. The colluvial
deposits are the result of landslide and gully erosion are common along the riverbank. The
alluvial and colluvial deposits constitute about 80-90% of the reservoir area. The section of river
valley is comparatively appears to be thin near the Gayalang bazar than other section.
4.1.4.4 Geophysical investigation
An Electrical Resistivity Tomography (ERT) survey was carried out in different location of
proposed hydraulic structural components. Findings from the interpretation of ERT surveys are
summarized as follows. Interpretive diagram of ERT are shown in Appendix-B. (Source:
Updated Feasibility Study report of AKSHEP, 2019).
At Damsite
At dam site, ERT profile shows that the left bank of Andhikhola is composed of weak and
compacted mass. The right bank in this dam axis is composed of 15-20m thick overburden
along with compact mass. The right bank is composed of compacted mass and bedrock of
dolomite. The left bank is composed of overburden, compact mass and bedrock of slate.
Resistivity values have also suggested that Andhikhola flows through the lithological boundary
of dolomite and slate.
Along Right bank
ERT profile along right bank of headwork shows that the upper layer comprises overburden
upto 8-10m from the existing ground surface. The middle layer comprises saturated fractured
bedrock and the lower layer is of dolomite. The depth of this dolomite bedrock has been
expected to find at the depth of 10-15m from the surface.
Along Left Bank
ERT profile along left bank shows that the upper layer comprises overburden (alluvium) upto
20m from the existing ground surface and compact mass. The middle layer in this interpretative
section has been expected to be of slate bedrock. The lower layer seen at the middle section of
this profile has been expected to be of sound bedrock, possibly of dolomitic slate.
Along Inlet Portal
ERT has shown four distinct layers along the slope of inlet portal. The top 8.0m thick layer
comprises overburden. This is probably the residual soil and fractured remain of bedrock at
some part. The second layer below the overburden layer is of bedrock of Phyllite and slate. The
third layer with comparatively high resistivity value suggests that this layer could be of dolomite
or dolomitic slate. The lowermost layer with low resistivity value suggests that this layer could
be of phyllite or slate bedrock
Across the Surge Shaft
ERT profile across the surge shaft shows two layer. First upper layer consists of saturated
overburden of variable thickness ranges from 3-5 m, second layer of this profile runs through 30
m to 70 m, and it contains sound bedrock of phyllite and slate. The depth of this layer extends

weathered and fractured rock of phyllite and it extends up to depth 30 m from the surface.
Along Headrace Tunnel and the penstock alignment crossing with surge shaft
Upper Layer of this profile contains overburden material, which is dry, and contains residual soil
deposits. The depth of this overburden ranges from 5-10 m. Second layer of this profile consists
of high resistive bedrock and extends below the depth of 30 m from the surface. This bedrock is
probably fresh, non-fractured slate. At center part of the profile, saturated highly fractured rock
is present which may be weathered phyllite, where some water source may present. The depth
of the layer extends from 30 -55 m from the surface. Similarly, a highly fractured, weathered
phyllite is present from chainage 160 -300 m and extends below depth 1-30 m from surface.
About 60 m left from Surge shaft along the slope
The upper layer of the profile consists of dry overburden that represent the residual soil
deposits. The depth of this overburden is varies from 3-5m from the surface. Similarly,
saturated highly fractured bedrock (phyllite) is also present and this layer extends up to depth of
15 m from the surface.
Along the powerhouse
ERT profile along the powerhouse shows that upper layer contains colluviums deposits. This
layer is found up to depth of 7 m from the surface. The second layer consists of highly resistive
very sound bedrock that is probably fresh and unweathered slate. This layer extended from 7 m
to 54 m from surface.
About 730 m downstream from surge shaft along the penstock alignment
ERT profile shows that the first upper layer composed of overburden deposits, which extends
from chainage 0 to 210m. The thickness of overburden ranges from 1 m to 2 m. This
overburden is resembled as residual soil. Below the overburden deposits, highly fractured,
jointed, weathered partly saturated, fractured rock phyllite and slate is present up to depth 50 m

150.00m long profile was mapped out along the slope due north of Galyang Bazaar chowk.
This North-facing slope has shown three layers within the mapped out zone. The top layer
comprises overburden or dry fractured bedrock, which is around 5-8m thick throughout the
profile. The second layer with low resisitivity value suggests that this is the saturated bedrock.
The thickness of this saturated bedrock is around 10m. The lowermost layer in this profile
comprises sound bedrock, which is at 15.00m from the existing ground surface.
Another 300.00m long profile was mapped out along the South facing slope, starts from the
petrol pump and ends at the paddy field downslope shows four layers within the mapped out
zone. The upper layer comprises overburden throughout the profile. Thickness of this
overburden is less than 5m on the slopy area whereas 5-8m at the foothills and flat area. This
overburden is the result of weathering of bedrock due to long exposure to the atmosphere. The
second layer below the overburden is of sound bedrock as suggested by comparatively high
resistivity. The third layer with low resistivity suggests the saturated bedrock. The lowermost
fourth layer seen on the right corner only is of sound bedrock .ERT diagram is presenting in

4.1.4.6 Landslide Hazard Analysis
The landslide hazard map has been prepared based on nine different thematic parameters that
directly contribute in landslide occurrence and sediment production. These controlling
parameters well describe topographical, geological, hydrological, and anthropogenic
characteristics of the study area. The parameters that are considered in preparing landslide
hazard map are: Slope angle, Slope aspect, Slope shape, Lithology, Soil thickness, Erosion
potentiality, Drainage density, Existing landslide density, and Distance from newly constructed
roads.
A portion of Andhi Khola watershed has been taken for present study. There are some active
landslides at present, the area comprises several marks of old landslides. The study area
covers an area of about 78.56 sq. km., where 77 small to large landslides are mapped. There
are different types of landslides, in which shallow slides and debris flows occurred on the
sloping terrain of right bank of Andhi Khola. A landslide hazard map is prepared by considering
above mentioned nine parametric information in ArcGIS environment. Individual rating of each
parametric classes are overlaid by sum through raster calculator to obtain an integrated hazard
map. The obtained map is reclassified into three classes: low, moderate, and high hazard
respectively. The landslide hazard map demonstrates spatial distribution of different zones to
landslide susceptibility. About 12% of the study area shows high hazard that is mainly
distributed on the right bank of Andhi Khola.

4.1.5 Seismology
Nepal is located along the active Main Himalayan Thrust arc, where the sub-ducting Indian
plate and the overriding Eurasian plate interact. The presence of three main fault line with in
country: the main central trust (MCT), the main boundary fault (MBF) and the Himalaya frontal
fault (HFF) are causes of earthquake in Nepal. As a result, Nepal is very active seismically.
There have been a number of devastating earthquakes over the past few decades, which have
caused the substantial damage of life and property. Ever since the first recorded earthquake of
1225 AD, Nepal has experienced a major earthquake in every few generations. Earthquake of
April 25, 2015 is the recent evident of such incidents.
Nepal Country Report (UNDP 2015) has identified 92 active fault within the country. Maximum
magnitude of earthquake that these active faults are able to generate has also been identified
according to the location of fault. Along the higher Himalaya tectonic area, faults can generate
maximum magnitude of 7 to 7.5, those along MCT 7.5 to 7.6, the mid-mountain 6.5 to 6.9, the
MBT 7 to 8 and HFF 6.5 to 7.5 Richter scale earthquake.
Seismic activities in proposed project area have been studied from past-recorded earthquake
and seismic hazard map of Nepal developed by Department of Mines and Geology. From
seismic hazard map of Nepal Figure 4-16 peak ground acceleration (PGA) on project area is
around 0.38g. All the components of project will be design incorporating the earthquake safety
factor and considering others potential risk in the project area.The project has proposed seismic
design coefficient as 0.6 for the design of structures. The seismicity assessment report of the
project area is attached in Annex B.

4.1.6 Air Quality
As the project area lies along the Siddhartha highway and some part in the rural setting, the
pollution levels are medium along the settlement such as Mathillo Galyang, Tallo Galyang,
Chiuri, Jholunge etc. The main source of air pollution is due to the vehicular moment along the
Siddhartha highway, earthern road along the reservoir area and construction activities like road,
buildings, etc. Other sources of air pollution are fugitive dust particles created by the movement
of public vehicles along the access road to the settlements and vehicular emissions. The overall
status of air quality at the project area is found to be good and within the range of acceptable
limits. In comparison to the powerhouse site, the air quality of dam site is better off. As the
powerhouse site is nearer to the highway, the air quality parameters are observed to be on
higher side than that of dam site as shown in the following table.

4.1.9 Watershed Conditions and Drainage Patterns
Drainage system also known as river system are the patterns formed by the streams, rivers and
lakes in a particular drainage basin. They are governed by the topography of the land, whether
hard or soft rocks and the gradient of the land dominate a particular region. As per configuration
of the channels, drainage system found in this area is accordant drainage pattern. In accordant
drainage pattern, dendritic drainage pattern (pertaining to a tree) is the most common form of
Andhikhola Storage HEP (180MW) Existing Environmental Condition
EIA Report 4-26 NEA-ESSD
drainage system in the project area. Andhikhola originates from Panchamul Lekh at an
elevation of about 2100 masl in the north.
The tributaries of Andhikhola are Bhagari khola, Bimrathe khola, Saradi khola, Ranguwa khola,
Seti khola, Baidi khola, Badh khola, Rindi khola, Darau khola, Lubdi khola, Chyandi khola,
Armadi khola, Baya khola and Phaudi khola. Since the lower part is composed of deep river
valleys and steep Mountain slopes, the rivulets are very short and steep with small size of basin
area. The drainage pattern of the Andhikhola in the catchment area of the proposed project is
shown in the following figure.

4.1.10 Soil Erosion and Land Stability
Soil erosion and landslides are main problems in country like Nepal where topography is steep
and geology is young and fragile. The overall stability of slope depends on the slope angle and
geological composition making the slope. High intensity rainfall, slope aspect, vegetation cover,
and climatic condition of the area are other governing factors for soil erosion and landslides.
Slope map of catchment area shows the dominancy of the slope ranging from 15º to 30º. Land
having slope angle ranging from 0º to 15º are confined on either side of Andhikhola at valley.
Reservoir area and its periphary have the dominancy of colluvium type of soil. The appearance
of streambed, sediment concentration at valley floor of river, alluvium deposition at bank of hill
Andhikhola Storage HEP (180MW) Existing Environmental Condition
EIA Report 4-27 NEA-ESSD
slope and high concentration of debris flows during rainy season shows that the catchment
area of Andhikhola has high potential of soil erosion and landslide.
All the exposed components such as dam site, intake site, reservoir site, tailrace outlet site, etc.
were study during field visit. During the field study, major landslides at upstream of dam site
were observed (Picture 4.2 .a and 4.2 .b). These landslides were in inactive stage during the
time of field study. Other many small active landslides were also observed in the surrounding
mountain slopes within the reservoir area and PAAs. At some section small patch of landslides
were observed due to the construction of road.

At dam site, both right and left bank of river has slope greater than 45º. The surface was
covered with colluvium soil. An intake of tunnel has been proposed on the left bank of the
Andhikhola and it seem to be stable with moderately steep rock cliff. The proposed powerhouse
site is located on the left bank of the Kaligandaki River on its alluvial terrace and the site is
seems to be stable. The bank of streams along Andhikhola seems to be quite stable since the
minor or insignificant scale of bank erosion was observed

4.1.11 Hydrology a. Stream Flow
Andhikhola is totally rain fed and Perennial River, originating from the Mahabharat range, which
is also one of the major tributary of the Kaligandaki River. The drainage area of the Andhikhola
is 475 km2 at the confluence with Kaligandaki River. The altitudinal variation is from 500 m at
the confluence with Kaligandaki River to 2482 m over a distance of 69 km along the
Andhikhola. The tributaries of Andhikhola are Bhagari khola, Bimrathe khola, Saradi khola,
Ranguwa khola, Seti khola, Baidi khola, Badh khola, Rindi khola, Darau khola, Lubdi khola,
Chyandi khola, Armadi khola, Baya khola and Phaudi khola.
Watershed of the proposed AKSHEP is showed in Figure 4.17. The average basin precipitation
based on the Isohyetal map is 3275.9 mm. The long term monthly generated data are given in
the Table 4.7. The long-term average flow at the dam site has been estimated as 32.1 m3/s.

b. Flood Hydrology
Probable Maximum Flood (PMF) has been derived from a regional relationship between PMF
and drainage area developed by the Kaligandaki. The estimated PMF at the dam site and
powerhouse are 4,800m3/s and 18,500m3/s respectively. Cofferdams will be designed to resist
flood events with a recurrence period of 1 in 20 years. Since this is a high dam project, the
spillway will be designed for discharge of flood of 1 in 10,000 year return period. Flood
frequency estimates for Andhikhola at damsite and powerhouse site is shown in table below.

4.1.12 Sedimentology
All reservoirs formed by dams on natural watercourses are subjected to some degree of
sedimentation. Provisions should be made for sufficient sediment storage in the reservoir at the
time of design so as not to impair the reservoir functions during the useful life of the project or
during the period of economic analysis.
Andhikhola Storage HEP (180MW) Existing Environmental Condition
EIA Report 4-31 NEA-ESSD
The sediment analyses done during the pre-feasibility study of the proposed Andhikhola
Storage Hydroelectric Project had adopted a value of 60 million cubic meter as the total dead
storage volume in the Andhikhola Reservoir, giving a siltation rate of 2526 m3/km2/yr, which is
primarily based on observed sediment data during the period from mid-June to early October
1995.
The sediment analyses done in 1997, 1998 and 1999 had estimated total sediment load of
about 0.39, 2.15 and 1.41 M tons giving a siltation rate of 600, 3224 and 2118 m3/km2/yr
respectively.
The sediment data collected during this Updated Feasibility Study shows that the total
suspended sediment load is about 0.30 Tonnes/yr. By considering bed load as 15% of
suspended sediment load, the total sediment load is about 0.34 Tonnes/yr.
4.1.13 Glacial Lake Outburst Flood (GLOF)
Since the Andhikhola is a rain fed river and originates below elevation of 2100 m, no study of
Glacial Lake Outburst Flood (GLOF) and associated impact due to GLOF is required for the
proposed project.
4.1.14 Existing Water users
The major upstream and downstream water users include hydropower and irrigation projects.
The existing Andhikhola HEP (9.4 MW) owned by Butwal Power Company (BPC) and existing
irrigation system associated with this hydropower project lies at upstream of dam. Kaligandaki
A HEP (144 MW) is located in downstream of the proposed dam. A number of projects are
planned in the downstream of powerhouse of the proposed AKSHEP. Existing projects in
upstream and downstream of the project dam site are discussed in this section.
4.1.14.1 Upstream of Dam
1. Andhikhola HEP (9.4 MW)
Andhikhola Hydropower Project of BPC is located about 600 m north-east from Tallo Galyang
Bazaar of Galyang Municipality. The average annual energy generated by this project is about
70.73 GWh in a normal year. The design discharge of plant is 4.87m3/s. The water use by
Andhikhola HEP for generation in 12 months as per PPA is shown in Table 4-10

2. Irrigation Scheme operated by AKWUA
The existing Andhikhola Hydroelectric Project diverts water not only to generate electricity but
also to provide water for irrigation facility. The irrigation scheme acquires water from Andhikhola
river through headrace tunnel to the shaft site from where water is diverted to open canal for
irrigation purpose. The irrigation system provides irrigation facility for a total land area of 500ha
in Syangja and Palpa district. Water user’s organization –Andhikhola Water User Association
(AKWUA), has been formed for the regular operation and management of the irrigation system.
The water use by Irrigation facility in 12 months as per agreement of BPC and AKWUA is
shown in Table 4-11

4.1.14.2 Downstream of Proposed Dam
1. Kaligandaki A HEP (144 MW)
Kaligandaki A HEP of NEA is located in downstream of proposed dam which is about 2.7 km
along the stretch of river from the dam axis. Dam site of the Kaligandaki A HEP is just about
200m downstream from the confluence of Kaligandaki river and Andhikhola, so both the rivers
have contribution in generating energy from Kaligandaki A HEP. Kaligandaki river has major
contribution wheareas Andhikhola has very minimum contribution in generating electricity.
2. Gandak Irrigation Project
Gandak irrigation project lies in the downstream of the proposed AKSHEP powerhouse. The
length of barrage of this project is 739 m, which is located across Narayani River in Nepal-India
boundary. This project irrigates about 46,900 ha land in Nawalparasi, Parsa, Bara and
Rautahat districts.
3. Gandak HEP (15 MW)
Gandak HEP, located at Suryapura of Nawalparasi, is a canal drop low head (6.09m) plant
operating in main western canal of Gandak barrage. This project uses water diverted from
Narayani River by Gandak irrigation project to generated electricity. The rated discharge of this
project is 103.84 m3/s. This project is located in downstream of the proposed AKSHEP
powerhouse.
4.1.15 Physical Infrastructures
Regarding the infrastructures in project area, there are number of bridges (Motorable bridges,
Trail bridges), water supply reservoir tanks, and roads (paved and unpaved). There are two
motorable bridges and thirteen number of trail bridges within the proposed reservoir area.
Similarly, IPP owned Andhikhola HEP with capacity of 9.4 MW, two number of drinking water
supply reservoir tank also lies within the reservoir area. Regarding to road, paved road in Tallo-
Galyang and unpaved road in Devithan, Sera, Illunga, and Bayatari are lies within the reservoir
area.
4.1.16 River System and Ecological Integrity
The Andhikhola is a perennial, totally rain fed River, originating from the mid-mountains, i.e.,
the Mahabharat Range. It is a left bank tributary of Kali Gandaki River joining at Mirmi, just
about 500 m upstream of the existing dam site of Kali Gandaki “A” HEP. Major water use in this
river is irrigation, hydropower, and domestic use. The river is also plays a vital role maintaining
the terrestrial ecological integrity of the area.

4.2.3 Dependency of Locals on Forest
In the PADs, 70.42% of total HHs are dependent on firewood as a main source of fuel for
cooking (CBS, 2011). Similarly, the questionnaire survey carried out for affected HHs revealed
that fuel wood (73.28%) is the main source of cooking purpose. About 54.12% of these HHs
collect fuel wood from community/government forest, 42.35% from private bushland/forest and
remaining 3.53%HHs purchase fuelwood from the local market.

4.2.4 Terrestrial Fauna
Forests area are primary habitats of terrestrial fauna. In the project-impact area, forest coverage
is very low compare to the national average. A small part of the total landuse/landcover of the
reservoir area is forest. Its quality, fragmentation and high human interference restricts its uses
for the majority of wild mammalians. Particularly, fragmentation and topographic location
surrounded by settlement is not favorable to the large number of wild faunal population.
Though the coverage of forest area is low, majority of the private land is barren (Kharbari)
occupied by trees. In the field, it is difficult to distinguish whether it is private unarable or
government forest area. Tall trees, bushes, and less human disturbances on the private
unarable (kharbari) resemble it as forest area. Therefore, private unarable (kharbari) may have
benefits to the wild fauna in the area.
Natural forest provide suitable habitat for a number of mammalian species. In the project area,
people reported Wild Cat (Felis chaus), Common Leopard (Panthera pardus),Rhesus Monkey
(Macaca mulatta), Terai Grey Langur (Semnopithecus hector), Porcupine (Hystrix indica), Indian
fox (Vulpes bengalensis), Malsapro (Martes flavigula),Common mongoose (Herpestes sp.),
Barking Deer (Muntiacus vaginalis), Jackal (Canis aureus), Chamero (Rousettus sp), Rats
(Rattus sp.) and Squirrel (Callosciurus pygerythrus), and other. During field study, occurrence of
Barking Deer (Muntiacus vaginalis), Rhesus Monkey (Macaca mulatta) and Rats (Rattus sp.)
was seen.
Picture 4-6: Wild Fauna of the Project Area
4.2.4.1 Birds
Natural forest, agricultural field, wetlands, villages, rivers, streams, gorges, and cliffs provide
variety of habitat for different species of birds. Sixteen bird species have been enumerated in
the project affected areas. The commonly reported birds of the project area are: Titra
(Francolinus francolinus.), Kalij (Lophura leucomelanos), House Sparrow (Passer domesticus),
House Crow (Carvus macrorhynchos), Jungle fowl (Gallus gallus), Dove (Streptopelia sp),
Swallow (Delichon nipalense), Cuckoo (Surniculus sp.), Lampuchchhre (Urocissasp.),Jureli
(Pycnonotus cafer), Koili (Cuculus sp.), Phisto (Orthotomus sutorius ), Owl (Strix aluco), Kokale
(Dendrocitta formosae ), Banjh (Falco subbuteo) and Eagle (Milvus migrans) (DFO-Palpa and

(Hemidactylus sp.), Common cat snake (Bioga trgonata), Rat snake (Pytas mucosus) are some
of the herpetofauna reported in the project area.
4.2.5 Protected Species of Flora and Fauna
Government of Nepal has protected some of the flora species under the Forest Rules, 1995.
Sal (Shorea robusta) is the only tree species found in the region, which is banned, for
commercial felling, transportation and export.
As per the National Park and Wildlife Conservation Act (1973) of Nepal, 26 mammal species
and 9 bird species been enlisted in the protected categories. Regarding fishes, Tor putitorais
found listed in IUCN endangered species and Neolissochilus hexagonolepis is near threatened.

• Species Abundance and Fish Composition
In the dry season, (during scoping phase) 83 fish of 12 different species were collected from the
sampling stations of Andhukhola and Kaligandaki River. Barilius bendelisis (faketa) contributed
55.42% Puntius terio (pothi) contributed 10.84%; Barilius vagra (faketa) contributed 8.43% of
the total fish catch.
Whereas, in the wet season (during EIA phase), 109 fish of 18 different species were collected
from the sampling stations of Andhukhola and Kaligandaki River. Barilius barila (Faketa)
contributed 19.17% Garra gotyla (Nakte buduna) contributed 17.43%, Barilius bendelisis
(Faketa) contributed 15.60 %, Puntius terio (Pothi) contributed 12.84%, and others.
Thisseasonal study shows thatBarilius bendelisis (Faketa) and Puntius terio (Pothi) are the
dominant fish species in the project area.

Fish migration and migratory pattern
The migratory nature of some fish species were studied on the basis of finding of relevant
literatures, interaction with local fishermen and direct observation. Among 34 fish species, six
species were long distance migratory species, five were medium distance migratory species
and rest are major residence species were observed and reported during field survey.
Habitat characterization Fish habitat at the sample station in both the Andhikhola and Kaligandaki River characterized in
terms of river flow is given in Table 4-28. At the surveyed stations, majority of habitat belongs to
the run type followed by riffle and then pools. No any rapid flow zone was observe near by the

4.3 Socio-economic and Cultural Environment
4.3.1 Project Affected Districts (PADs)
Proposed AKSHEP affects two districts of two province of Nepal, namely Syangja (Gandaki
Province) and Palpa (Province No. 5). After the state's reconstruction of administrative divisions
as of 20 September 2015, there are 14 RMs and 7 municipalities in two districts (6 RMs and 5
municipalities in Syangja District and 8 RMs and 2 municipalities in Palpa District). These PADs
cover an area of 2,537 sq.km. (Comprising about 2.08% of total national area).
4.3.1.1 Demographic Characteristics
The proposed AKHEP is located in Syangja District of Gandaki Province and Palpa District of
Province no 5, of Nepal. The total area of the districts is 2,537sq.km. According to the data of
Central Bureau of Statistics (CBS) 2011, the total population of PADs is 550,328 with 241,673
(43.91%) male and 308,655 (56.09%) female. Population of PADs is about 2.08% of total
population of the country (26,494,504). The population density of the PAD is 216.92
(persons/sq.km). There are 128,172 HHs and the average HHs size is 4.29.
Population growth of the district from the last decade is negative by 0.59 percent. This is
because the PAD located in high hill area having less agricultural land and migration towards
nearby urban areas. People of the PAD go to the terai area for better opportunities that leads to
low population growth rate. On the other hand, the increasing outflow of migrant workers and
low fertility and mortality rate due to GoN policy are other factors for low population growth rate
in PADs. Details demographic status is presented below.
The average literacy rate is 67.64%, which is higher than the national average (65.9%),
however, the literacy rate of Rukum East district is lower than national average. The urban
population of PAD is 50.83%. The number of the urban population has highly increased from
the last few years since the GoN has recently announced many new municipalities by
incorporating existing VDCs. The demographic characteristics of the PADs are given in the
table below.

4.3.1.2 Social Demography
a. Caste/Ethnicity and Mother Tongue
As other districts of Nepal, the PAD is diverse in ethnic composition. The indigenous caste
group Magar is the dominant caste residing in the PADs especially in the countryside. Out of
total population of Palpa District, about 52.30% are of Magar community, whereas in Syangja
District, this community covers 21.47% of total population. Population of Dalit caste groups
(Kami, Sarki, Damai/Dholi etc) is also significant in the PAD. The details of caste/ethnic
composition PADs are given below.

d. Health and Sanitation
● Crude Death Rate (CDR)
The average estimated CDR of PAD is 9.33 which is higher to national CDR level i.e. 7.30;
deaths per 1000 population. Certain variables, i.e. availability of health facilities, higher per
capita income and high literacy rate tend to decrease CDR whereas some variables, i.e. high
population density, lack of water supply and poor sanitation tend to increase CDR. Syangja
District has slightly higher CDR (9.52), whereas Palpa has comparatively lower (9.14).
● Infant Mortality Rate (IMR)
The infant mortality rate (IMR) is the number of deaths of infants under one year old per 1000
live births. The estimated average IMR for total males and females in PADs is 20.64, which is
lower than national level (40.5) where male IMR is 24.92 and female IMR is 16.99. The IMR
decreases continuously from last few decades, which reflect the awareness of local towards
health facilities.
● Life Expectancy
Life expectancy of both project districts is higher (Palpa 71.3) and (Syangja 70.1) as compared
to national level (66.6). The lower life expectancy reveals the poor health condition of the area.
● Health Institutions
District level health facility is available in district headquarter besides these government health
centers other health clinics are also provides their services in districts; Expanded Program on
Immunization (EPI) is a health clinic works in child care. Female Community Health Volunteer
(FCHV) is works in field of women's health and awareness field.
● Disease
The major diseases reported in the project area as according to the local health posts Diarrheal
Disease, Intestinal Worm, Acute Respiratory Infection, Skin Diseases, Ear Infection, Gastritis,
Vitamin/Nutrition Deficiencies and others. In case of emergency, the hospitals at near city
(Tansen, Butwal, Pokhara, and Kathmandu) are referred.
GoN declared Nepal open defection free nation (ODF). In the field visit, the study team observed all of households along the reservoir, powerhouse site, surge tank site use toilet for defection. In house sanitation condition was found very well. People seem aware about their in-house and surrounding hygiene.

e. Migration Patterns
People generally migrate from hilly area to flat area and rural to urban area for better
opportunity of their life. The outer migration is very common in the project area. The young
generations migrating to abroad seeking employment opportunities are common. The gulf
countries like Saudi, Qatar, UAE (Dubai) and in-abroad are the main destination of the migrant
in the project affected area. The general factors leading to migration of the population of the
project affected area include poverty, other natural calamities and seeking for better
opportunities, social services as well as security and other infrastructural facilities.

g. Gender
Gender equality is a key component of human development, but overall by sector Nepal still
has a gender gap, so as the PADs. The female population exceed the male population; as a
result, the sex ratio is low (78.30) mainly due to the huge outflow of youths from Nepal to
abroad. The female literacy has remarkably increased in the past decades still it is low 69.54%
in PADs whereas the male literacy (85.50%). There has been a rise in female-headed HHs due
to the increase in male migration.
However, economic empowerment of women is still a challenge in PADs. Only 6.18% of female
headed HHs have holding on assets; both house and land and this figure is still low in case of
holding of land only (4.70%) which is very low than the national average (10.71% and 9.00%)
(CBS, 2011). In addition, women's economic activity is still low in non-agriculture sector
(34.23%) possibly due to a lack of education and a tradition of working in agriculture. About
65.77% women of PAD are engaged in agriculture sector, self-employment activities and /or
unpaid family labor.

b. Occupation and Employment
The PAD is the hilly region of the county having minimum fertile land and irrigation facilities.
The subsistence farming and rearing livestock are the major occupation of the families for their
livelihood. As a result, large number of youths goes to foreign employment for their livelihood.
Besides, rest of the people is engaged in business, government service, labor, agro-based
industries, livestock and poultry farming etc. Major occupation of the people (10 years and
above) of the PADs is given below.

a. Agriculture
Agriculture is the leading economic activity in PADs. Out of total HHs, about 82.36% in Palpa
District and 83.64% in Syangja District are engaged in agriculture. However, the agricultural
land of PAD is 51.20% of total district land but only 66.91% of total agricultural land is used for
cultivation. (Source: District Profiles). Main limitation factor in agriculture development in PADs
are the lack of irrigation facilities throughout the year (17.06%) and traditional farming practice.
On other hand, large numbers of agriculture labors are in foreign employment. The cropping
patterns depend on factors like land types, soil quality, rain fall pattern, and seasonal variations
of temperature. In the project area paddy, wheat, maize, millets, barley, pulses, mustard are the
most important cereal crops and potato, sugarcane, fruits and vegetables are the major cash
crops (Table 4-22).
Livestock raising (mainly cow, buffalo and goats) is an important subsistence farming activity in
the project area. Livestock provide meat, milk, eggs, wool and a cash income. Livestock is an
integral part of cropping activities producing organic fertilizer. The potential of beekeeping is
high in PADs as there is the availability of local bee in the districts.

4.3.1.5 Road and Transportation
Infrastructural development (road and transportation development) is the major factor of
development. However, the road facilities in both districts seems to be good. The district
headquarters of Tansen and Putalibazaar, is linked by black topped road, Siddhartha Highway
and there are regular bus services from major cities of country. Almost all places of the district
have linked with rural road. There is no any airport facility in PADs, nearest airports are
Gautambuddha Airport, Bhairahawa and Pokhara—Airport, Pokhara.
4.3.1.6 Cultural Demography
The PAD has diverse ethnic composition. The indigenous caste group Magar and Dalit caste
group are the dominant caste residing in the districts especially in the upper part. Out of total
population, about 36.10% are of Magar community whereas Dalit caste groups are 12.16%.
These communities have their own language, tradition and culture. Having different culture and
tradition, however, they live in the same society with social harmony and brotherhood. There is
no any conflict between them for using common property resources and each community
respect each other's norms and values.
4.3.2 Project Affected Area (PAA/RM/Municipality)
The implementation of proposed SHEP affects two municipalities and two RMs of PADs, two

4.3.2.3 Social Demography
a. Caste/Ethnicity and Religion
In Nepal the Adivasi Janajati are recognized Indigenous Peoples having their own territory,
language, traditional rites and customs, distinct cultural identity, social structure, and history.
The EIA identified the presence of Adivasi Janajati living in mixed communities within PAA with
the prominent inhabitants of the PAA are Indigenous group-45.90%; Largest community is
Magar which exists (35.03%), Gurung (6.39%), Newar (2.55%) and Gharti/Bhujel (1.16%).
Magars are mostly found in and around PAA; they are considered as disadvantaged ethnic
group. Majhi and Bote (0.45%) have presence in the area. 11.73% are Dalit in the PAA. They
have rich tradition of music and culture. In fact, ethnic group and indigenous, residing in PAA
share the same opportunities including natural resources, economic and political opportunity,
equal rights on constitution. They do not have distinct political institution but culturally different
from the mainstream groups.

c. Education and Literacy
Literacy status is a major indicator to describe quality of life, high literacy rate is good quality of
life value. According to CBS 2011, the total population (5 years and above) of the project area
is 105,386 (91.83% of the total population) with male 42.79% (45,092) and female 57.26%
(60,348). Of the total population 5 years and above, the average literacy rate of the project area
is 75.15% similarly, among male population 86.48% are found literate and 69.9% in female
category.
The field observation shows that most of the people are aware about the education of their
children either boy or girl. This indicates that the educational status of mail is good and female
is satisfactory in project affected RM/municipality. Educations of all levels (primary to college
level) are found in project affected municipality and secondary level education is available in
(primary-12 class) project affected RMs/municipalities. Besides government school, there are
private boarding schools and non-formal educational program also exist in project area.
According to CBS report, the school attainment of age 5-25 is 79.81% with mail (85.7%) and
female (74.72%).

There has been a considerable improvement in the educational attainment at all levels of
education over the years. However, a large proportion of the people of PAA have only a basic
level (1-5) and (6-8) of education. Among the population who completed their education, 27.9%
had a basic level (1-5) education followed by 18.5% with basic (6-8) level education and 20.3%
with secondary (9-10) level education. There are only 2% population in PAA achieving graduate
or post graduate level of education. School drop out from the basic level (6-8) and secondary
(9-10) is rare in PAA. There are some population (3.7%), who are not having formal education
from any schools.

d. Migration
Migration is the common phenomenon of all part of Nepal so as project area. People of the
project area are migrated to urban areas and Terai for better opportunities; better facilities,
employment opportunities, business, medical service and good life style. In the same way, out-
migration (seasonal migration), especially to the neighboring country and abroad (mainly Gulf
countries) in the quest of work is widely seen in the project area. According to CBS (2011), the
absent population of the PAAs is 19,993, which is 17.42% of its total population and 3.63% of
total district population (550,328). The detail of absent population is given in the table below.

e. Public Health, Drinking Water and Sanitation
The public health condition of the PAA seems to be satisfactory. All the affected
RMs/municipalities have access to health centers with all types of physical facilities. The
primary health care centers are there in each ward, some settlements are little bit far from these
facilities, but these settlements have road access.
The health situation of the project area is satisfactory and water related diseases (diarrhea,
dysentery, influenza, cough/cold, typhoid) and common fever, pneumonia, pox, gastric,
measles, jaundice skin diseases urinary tract infection, chronic bronchitis etc. are still common
here. There is a primary health care center in each ward. The health service in the project area
is delivered through the existing district government hospital, private hospitals, health post, sub-
health post, and clinics which provides local level health services satisfactorily. Traditional
healing by Dhami, Jhankri and Lama is also practiced in the project area. Awareness level
towards health and sanitation (particularly towards safe drinking water, use of toilets etc.) is
satisfactory in the project districts.

Picture 4-11: Toilet Facilities (villages of Project Area)
Andhikhola Storage HEP (180 MW) Existing Environmental Condition
EIA Report 4-69 NEA-ESSD
The major sources of water for domestic purpose of the PAA are personal or public piped water
(77.68%), covered/ uncovered well, spout water, tube-well and others; however, it is observed
from the walkover survey that most of the HHs in the project area use tap/piped water
connected directly to the water sources.

f. Gender Status
Gender gap was seen in the project area as other parts of Nepal. The sex ratio of the project
area is 76.56% which is a little bit lower than the district level (78.30%), which indicates that a
large portion of male population are migrated to the foreign country for employment opportunity
and thus also increase the burden of workload to female HHs. This has rather feminized the
agriculture system of the project area. The female literacy has remarkably increased in the past
decades still it is low 69.9% than the male literacy (86.48%). There has been a rise in female-
headed HHs in the project area but this is due to the increase in male migration and economic
empowerment of women is still a challenge.
In addition, women's economic activity is still low in non-agriculture sector possibly due to a lack
of education and a tradition of working in agriculture. Their participation is more than that of
men’s in almost all agricultural activities. Livestock keeping is also women’s prime
agricultural activity and the largest amount of women’s micro credit money goes for
livestock raising. In spite of women toiling so hard in agriculture, it is characterized by “below
subsistent” productivity and insufficient even for “own consumption”. The decision making
process on economic activities is exercised by the both male and female. The average daily
wage rate of women for manual works in the project affected area is NRs. 800-1000 which is
slightly low as compared with male NRs. 1000-1200.

EIA Report 4-70 NEA-ESSD
4.3.2.4 Economic Demography
a. Economically Active Population
CBS 2011 has defined the population of the age group of 10 years to 59 years as economically
active population. According to which, the total population of age 10 to 59 years of the PAA is
calculated to be 79,299 which is 69.10% of the total population of the PAA. Hence, there is
69.10% population categorized as economically active, which is higher than district (57.40%)
and quite similar as national average (69.54%). Similarly, there is 30.90% dependent
population on which 19.78% are 10 years and below and 11.12% are senior citizen (sixty years
and above age).
The child dependency started to decrease as compared to CBS 2001 conversely old age
dependency is increasing. This could be due to the decrease in fertility and mortality rate. A
detail of economically active and inactive population is shown below.
Figure 4-30: Economically active Population of PAA
Source: National Population and Housing Census, CBS, 2011
b. Landuse and Farming
Agriculture is the leading economic activity in project area. But the main limitation in agriculture
development here is water logging by drainage congestion, irrigation shortage and traditional
farming system. The cropping patterns are depended on factors like land types, soil quality,
rainfall pattern, and seasonal variations of temperature. In the project area paddy, wheat,
maize, millets are the most important food crops and oilseed, potato, fruits and vegetables are
the major cash crops.
c. Occupation and Employment
Self-employment is only option to keep oneself as employed. The overwhelming majority of the
local people are employed in the agricultural sector (subsistence farming). Livestock rearing
and rain fed farming are the major agricultural activities of the project area. At the local level,
employment opportunity is very low.
Picture 4-13: Agricultural land in PAA
Andhikhola Storage HEP (180 MW) Existing Environmental Condition
EIA Report 4-71 NEA-ESSD
d. Livestock
Livestock raising for domestic use and income generation is a major economic activity HH of
PAAs. Mainly cow, cattle, buffalo, sheep and goats is an important subsistence farming activity.
Livestock provide meat, milk, eggs, and a cash income. Large livestock are also an integral part
of cropping activities, providing draught power and producing organic fertilizer. Livestock is
grazed on private and communal land.
Horticulture Crops
The project area has vast potentiality of temperate fruits and other high value commodities such as orange, guava, peach, plum, and pear cultivation, including bee farming. e. Tourism Activities and Aesthetic Value
Tourism activities are growing rapidly since last few years in PAA. Project area has lot of
potential of tourism. Aesthetically the project area is attractive. The natural views of the
landscapes of mountains, hills, basins including river systems are amazing. The area is rich in
its wilderness and scenery. Through the project site higher snow picks can be viewed easily.
The view of huge high rocks including green forest sites makes the areas` aesthetic seen
incredible. Kaligandaki A HEP, Tansen Durbar, Ranimahal etc are major attraction for tourists.
f. Income and Expenditure Pattern
a. Income Source
The main income making sources of the people of PAA are agriculture and non-agriculture or
off-farm activities. Agriculture related sources include income from sale of potato, food grains,
fruits, vegetables, livestock and honey farming. Income from agriculture and livestock provides
the subsistence requirements for the families. The off-farm sources of income include service,
business, trade, wage labour, etc. Foreign remittance and pension of Indian army is one of
significant income sources to many HHs in the project area as in other parts of Nepal.
b. Expenditure Pattern
As far as PAA concerned, the level and structures of consumption are more or less similar to
the other part of the country. Most of the expenditure is for the consumption of food items
following education, health, energy and other non-food items.
g. Cottage and Small Industries
The PAA have medium and small scale industries. However, there are few cottage industries
such as Doko-Namlo weaving, fruits processing and furniture carving at small scale in HH level.
Picture 4-14: Different Income Generating Activities in the PAA
Andhikhola Storage HEP (180 MW) Existing Environmental Condition
EIA Report 4-72 NEA-ESSD
h. Fishing Activities
Some local people involve in fishing activity in Aandhi Khola. However, there is no any fishing
community and commercial fishing activities in andhikhola in the project area.
4.3.2.5 Ownership of House
Ownership of house/housing unit is a major indicator to describe quality of life value. Most of
the houses in PAA are kacchi types, brick/stones bonded with mud (75.03%) followed by semi-
kachitypes, brick/stones bonded with cement (22.21%). After development of road facilities new
houses of roadsides are made RCC types.Most of the HH have their own house for resident
(86.93%), 11.68% HH are lives in ranted houses. Some families lives in institutional residence.
4.3.2.6 Market Centers
The major market centers in the PAAs are Mirmi, Galyang (Tallo Galyang, Pari Galyang),
Waling, Jaipate, Batuwa, Aandhi Muhan, Jholunge, Jiro Kilo and Majhuwa.
4.3.2.7 Religious, Historical, and Aesthetic Sites and Value
Shiva Mandir, Chakradevi Mandir, Radha-Krishna Mandir, Church are the major religious
places in PAA.
Picture 4-15: Church, Tallo Galyang and Radha-Krishna Mandir, Elunga
4.3.2.8 Infrastructure and Service Facilities
a. Transportation
Almost all wards of project area is linked with motor-able road. District headquarters of Palpa
and Syangja is linked by black topped road (Siddhartha Highway) and ward level roads are
linked by blacktopped and earthen road, there are regular bus services from major cities. The
inner project areas are also almost accessible by gravel or rural earthen roads. Currently,
government has taken the policy to link the RMs to district headquarter through road thus
makes many rural roads in all RMs. But these roads are almost earthen road and are accessed
only in dry season.

Picture 4-16: Inner Section Road Suspension Bridge and Motor-able Bridge in Project Area
b. Communication
Communication services through mobile and Code Division Multiple Access (CDMA) are
available in RMs and municipalities. Similarly, postal and modern communication facilities like
email/internet and fax are available in major settlements. Cable network is accessible in almost
all part of the project area. Radio and Local Frequency Modulation (FM) network is within the
access of public. Local and national newspapers are available in the project area.
● Energy Use for Cooking and Lightning Purpose
The PAA is totally connected with local grid system of BPC. Nepal's highest energy generation
project Kaligandaki-A HEP is located at Kaligandaki RM. However, the Aadhikhola (BPC) HEP
also give service to PAAs. According to Nepal Electrification Statistics, 2019 all the affected
RMs and Municipalities of Syangja District are fully electrified and Rambha RM of Palpa District
is 95.25% electrified. But data of CBS, 2011 there are 90.91% HHs use electricity and 6.78%
HHs use kerosene for lightning.

The main sources of cooking and heating energy is fire wood in the project area. About
78.61% HHs of PAA have been using fuel wood for cooking and heating and remaining 17.36%
use LPG and Kerosene for cooking purpose. The LP gas is mainly used in hotels and some
private HHs of market center.

4.3.2.9 Law and Order Situation
The existing law and order situation of the project area was observed to be normal. The District
Administration Office and police office have maintained the law and order in the area.
4.3.2.10 NGO’s and INGO’s Activity
There are many NGOs, clubs, cooperatives, mother groups, etc. are working in the field of
water supply, sanitation, sports, women awareness, saving mobilization and income generating
activities in the project area.
4.3.2.11 Cultural Demography
Like PAD, the PAA has also diverse ethnic composition. The indigenous caste group Magar
and Dalit caste group Kami are the dominant caste residing in the PAA. Out of total population,
about 35.03% are of Magar community whereas Dalit caste groups Kami, Sarki and
Damai/Dholi are about 11.73%. These communities have their own language, tradition and
culture. Having different culture and tradition, however, they live in the same society with social
Andhikhola Storage HEP (180 MW) Existing Environmental Condition
EIA Report 4-76 NEA-ESSD
harmony and brotherhood. There is no any conflict between them for using common property
resources and each community respect each other's norms and values.
In PAA, there is the tradition of doing any social work with mutual participation. For any type of
community development work (eg. to make irrigation canal/ upgrading of local road/ source of
drinking water maintained), one member of every HH need to physically present and contribute
his/her effort. Such cultural practice is call JHARA in local language. If any HH cannot
participate in such social work, he/she has to pay certain price as penalty.
There is another cultural practice in PAA. In agricultural practice, there is not the tradition of
giving cash payment to agricultural labor. The neighbor must go support for his/her neighbor; in
return, his neighbor will come and support him when he needs. This type of cultural practice is
called PARMA in local language.
4.3.3 Project Affected Families (PAFs)
4.3.3.1 Demographic Composition
Among morethen 1200 project affected families, only 1144 Household survey was conducted to
collect socio-economic status of the project affected families (PAFs) that are directly affected by
different components of the project. Morethen 56 HHs were meesing due to absence during
survey time.The total population of surveyed HHs is 6,936 including 3,645 (52.55%) males and
3,291 (47.45%) females. The sex ratio and average HH’s size is 1.11 and 6.1 respectively.

c. Literacy Status
Average literacy rate of the surveyed population (population of 5 years and above) is around
71.9% with male and female literacy rate are 75.5% and 67.8% respectively. Among the literate
population, the number of populations having intermediate level of education is higher. The
trend of leaving the school after gaining primary level of education is not shown among PAFs.
This is due to awareness towards education. The following tables depict the literacy status and
their education attainment of the surveyed population.

e. Health and Sanitation Condition
The public health condition of the surveyed HHs is seemed satisfactory. Since the reservoir and
dam area are the urban/semi urban and rural area, it have physical facilities. There are primary
health care center, hospital and health posts.
Almost surveyed HHs are aware about their hygiene and conscious towards hygiene related
problems hence in-house and surrounding sanitation and hygiene condition is found
satisfactory. Not all of the surveyed HHs are using toilets/latrines.
About 16.4% of surveyed HHs burn their solid waste, where around 73.4% dump at safe
location. Table below shows solid waste management practiced by PAFs.

e. Food Sufficiency and Deficiency
The HHs survey indicates that majority of the surveyed HHs have food deficiency. Since the
project area is hill area with less fertile land and lack of sufficient irrigation facility, the
productivity is also less. These people do not have the knowledge of farming new product. They
all depend upon their traditional pattern of farming. The production of it is not enough to sustain
for whole family of PAFs during whole year. Livestock rearing is another means of sustainability
Andhikhola Storage HEP (180 MW) Existing Environmental Condition
EIA Report 4-82 NEA-ESSD
of the PAFs. HHs, who have the food deficiency, generally do the supporting works like labor
wage and small business. Local people reported that at least of one member of PAFs go to the
abroad, during off-season of farming to earn some money. The following tables show the detail
of the sufficiency and deficiency of food of the PAFs.

One major component to see the socio-economic condition of the surveyed HH is their loan
status. HH survey shows that most of the HHs have the burden of loan. Since, living standard
of these people is low and their agriculture production is not enough for their livelihood, they
take loans for fulfilling their daily needs. These people take loans for different purpose (daily
livelihood, education, health treatment, marriage/ritual and food/ clothing etc.) Among the HHs
who have the burden of loan, majority of them take loans for meeting their daily basic needs.

• Educational Status of IPs
The literacy rate of the IPs is 65.27% which is lower than total FAFs (71.9%). This is due to the
lack of awareness towards education. Now a days, the level of awareness has increased and
the people of the area are sending their children (either boys or girls) to school for education.

• Occupational Composition of Surveyed IPs Population
During the field survey, it was observed that the main sources income of the IPs of project area
are agriculture farming and livestock raising. The project area is famous for citrus farming.
Since the production from their agricultural land is not enough for their livelihood, it is seemed
that most of the male members of the affected wards are migrated to the neighboring country
India in the quest of work.

• Food Sufficiency and Deficiency
The survey indicates that majority of the surveyed IPs have food deficiency. Since the project
area is hill area with less fertile land and lack of sufficient irrigation facility. These people do not
have the knowledge of farming new product. They all depend upon their traditional pattern of
farming. Livestock rearing is another means of sustainability of the IPs. HHs, who have the food
deficiency, generally do the supporting works like labor wage and small business. Local people
reported that at least of one member of IPs go to the abroad, during off-season of farming to
earn some money. The following tables show the detail of the sufficiency and deficiency of food
of the IPs.

EIA Report 5-1 NEA-ESSD
5 ENVIRONMENTAL IMPACTS
This chapter addresses the likely adverse as well as beneficial impacts in the construction and
operation phase of the AKSHEP. Other Adverse and beneficial Impacts on physical, biological,
and socio-economic and cultural environment that are not anticipated and identified during the
EIA, if it appears during the period of project construction, will be duly and compulsorily taken
into account and addressed by the project proponent. The construction and operation of the
project will result in changes to the existing baseline condition. The general discussions are
organized in three categories: namely physical, biological, socio-economic, and cultural
environment, and divided into the construction and operation phases. The beneficial impacts
are discussed under a separate heading.
5.1 Physical Environment The main physical impacts on the environment, those associated with land stability, hydrology,
river morphology, air noise and water quality and other issues, which were identified during the
scoping phase are important issues considered in the EIA. The major impacts anticipated
during the construction and operation phase are discussed in the sections below.
5.1.1 Construction Phase
5.1.1.1 Impact on Topography
Project components include the construction of dam, powerhouse, surge tank, spoil and muck
disposal site, access road, etc. The construction of these components will certainly change
topography as these works involved clearing vegetation, excavation and another earthwork. At
headwork, construction of dam and diversion dam will create an impoundment at its backside.
The construction of other project components like labor camp and other project facilities will
change in landscape. In addition to this, construction of access road, muck disposal area,
stockpiling area, quarry sites etc. also make changes in landscape of local area. The visualized
impact on topographic changes is considered to be direct in nature, medium in magnitude, site
specific and for long term.
5.1.1.2 Impact on Land Use and Land Take
The project needs land for the construction of physical infrastructure and formation of reservoir.
Hence, project will be acquired land permanently for permanent structures and reservoir area.
The permanent land acquisition will be about 913.00 ha. The permanent land acquisition will be
significant because land taken is irreversible and will be taken for the entire project period. In
addition to this, project will be required land for labor camps, quarry sites, spoil and muck
disposal area and other purposes, which will be acquired temporarily on lease and return to
owner after completion of works. The temporarily land acquisition will be about 52.82 ha.
Approximately 965.82 ha of land use will be permanently and temporary changes during the
construction and operation period of project. A land use change will occur in approximately
276.70 ha agriculture land and 17.76 ha of forestland including government forest and
community forest. Approximately 442.66 ha private Kharbari in form of grassland and bush will
be impacted during operation period of project. Nearly 168.02 ha of other land will be impacted
which include riverine flood plain. During construction period total land will not be affected
because major land of project lies in reservoir area which will be utilized in operation period
only. The impact on land use during construction period will be direct, high in magnitude, long
term in nature and site specific.
Andhikhola Storage HEP (180 MW) Environmental Impacts
EIA Report 5-2 NEA-ESSD
5.1.1.3 Impact on Air and Noise Quality
During construction period, there will be use of heavy equipment, use of crushing machines,
vibrating machine etc. for excavation of earth and construction of project component that can
generate significant amount of dust into atmosphere. The movement of vehicles to transport
construction materials from quarry site to construction site, transport muck to safe disposal
area, transport external material to construction site etc. will also generate dust resulting air
pollution. The tunneling works such as drilling, blasting will also generate high amount of dust.
As the construction work will be carried out during dry season, emission of dust is expected to
be high at the construction sites. Construction activities will also generate noise and vibration at
the project site. The main activities that will generate noise and vibration are blasting, use of
batching plants, movement of heavy equipment, use of drilling, generators, pumps, etc.
Construction of project is likely to influence the existing condition of air and noise level and
affecting human, wildlife and livestock of the project area. As the project construction site is far
away from major human settlement near to the forest major impact will be on wild animals.
Thus, the nature of the impact will be direct, medium magnitude, medium term and local.
5.1.1.4 Impact on Water Quality
Construction activities of project components will have direct and indirect effect on the water
quality of Andhakhola. Construction of project components like dam, intake directly effect on the
riverbed and river bank either by additional external material or by disposal of surplus materials.
Similarly, while constructing tunnel and powerhouse unwanted water will be disposed to nearby
water course which will ultimately polluted the nearby water bodies.
Quarry site is proposed within the reservoir area, thus the river will bear the impact. Similarly,
muck disposal area are also proposed near to the bank of river and hillside slope. During
monsoon season, rain water erode and transport disposal material from these area into nearby
river. This will affect the quality of water. In addition to this improper management of waste,
both solid and liquid, generated by workforce directly or indirectly involved in the project will
result in increased BOD and ultimately degrade the quality of water.
Project construction activities are likely to increase the turbidity, suspended solids, dissolved
solids and BOD of both rivers and nearby watercourse. This might have an adverse impact on
the aquatic life of the river and the public health of the local people of downstream of project
area. However, the impact on public health will not be served as people in the area do not use
river water for drinking purpose. Thus the impact on water quality will be direct, medium in
magnitude, medium term and local.
5.1.1.5 Impact in Hydrology and River Morphology
During construction phase there will be hardly impact on the hydrology river. The use of water
in the construction work and in labor camps will have little impact on the flow volume.
Construction of intake, dam, and adit portal requires some diversion of river. Minor change in
riverbed morphology is expected. Similarly, excavation of construction materials from riverbed
may lowered and may change its course within the limits of river. Thus, the impact on hydrology
and river morphology is expected to be direct, low in magnitude, short term and site specific.
5.1.1.6 Impact on Soil Erosion and Land Stability
The project mainly consists of construction of dam, intake, tunnel, powerhouse, access road,
and surge tank. These activities required excavation of earthwork either on the surface or
beneath the surface. Dam, intake, and powerhouse sites are proposed on stable area where
Andhikhola Storage HEP (180 MW) Environmental Impacts
EIA Report 5-3 NEA-ESSD
quite sound geological strata are available. Thus, there is low risk in soil erosion and land
stability during construction of these activities. However, during construction of access road cut
slope as well as fill slope has high risk in soil erosion and landslide. The activities promoting
excessive soil erosion and land instability in construction phase is mainly related to the
construction of access road.
a. Main Access Road Construction
The main access road to connect powerhouse and dam site passes through relatively stable
land to steeper forestland. Since the section of road, involve cutting of slopes in agricultural
land, private barren land and forestland soil erosion, minor erosion of is expected. Road
construction practice with balance cutting and filling can be adopted in some section of road to
avoid associated consequences risk. However, spoil disposal in the adjacent agriculture fields
and forest may degrade agricultural land and standing vegetation of forestland.
b. Secondary Access Road Construction
The adit-2 access road passes through the mild slope to steep terrain with stable geology and
landform. Road construction in these relatively steep areas means mostly cutting of the slope
material to excavate the road’s formation width. Cutting of the steep slope thus increase the risk
of slope instability and potential of small to large scale mass wasting. Disposal of excess
excavation spoils immediately below the cut slopes is expected to cause extensive degradation
of the standing down slope vegetation making the slope suitable for erosion. Agricultural areas
down slope the road are potential for sedimentation and siltation and may convert in barren
area unsuited for agriculture.
In rainy season, disposal material may be transported by water to the down valley land and
nearby water bodies, which may create problem in the gross agricultural productivity,
sedimentation in down valley land and streams.
c. Quarry and Barrow Pit
As quarry sites and borrow pit areas are purely excavation works it may has a high potentials of
erosion in the excavation sites and sedimentation in the nearby drainage channels. Quarry site
for construction of dam is proposed in uphill side of dam axis. Erosion and sedimentation is
expected during rainy season and degradation of the down valley land. As there is no
settlement in down valley, impact is expected to be low.
For quarry site of sand, bed material of Kligandaki river at Asardi is proposed. Excavation of
riverbed material likely to lowers the level bed of river. Since considerable volume of material is
available in floor of valley and river, adverse impact is not expected.
d. Construction of Tunnel
During construction of tunnel, the land stability will be very critical if there are instabilities along
the tunnel line. Use of high blasting technique may induce surface instabilities due to vibration
effects particularly in areas where ground surfaces are much closed to tunnel line. Adequate
study and precaution will be done to minimize the effect due to tunneling. Thus, the impact on
soil erosion and land stability is expected to be direct, medium in magnitude, medium term and
local
5.1.1.7 Impact due to Waste, Spoil and Muck Generation
Project will generate waste, spoil and muck through different kind of activities. Some amount of
which is used in backfilling and land development. Further waste generate from labor may also
Andhikhola Storage HEP (180 MW) Environmental Impacts
EIA Report 5-4 NEA-ESSD
create adverse effect existing environment. Generation and management of waste is
continuous process in construction phase.
Three muck disposal area are proposed in different location to manage the exceed material
generated from tunnel. Out of three area, one of the area is selected in agriculture land, second
one is selected in private barren land, and third one is selected along the bank of Kaligadaki
River as shown in figure 2.5. Detail area occupied by these sites is shown in table 2.6. A
proposed agricultural area is expected to convert in barren area unsuited for agriculture
resulting loss in agriculture productivity. Similarly, a muck disposal area in private barren land
degrades the standing vegetation of the site and muck disposal area that is proposed near to
the river bank is likely to degrade the water quality.
Disposing any kind of spoil near to water bodies and other land will be strictly managed to avoid
adverse condition on existing environment. Proper management and treatment will be done in a
planned way before disposing any kind of spoil and waste. Proper management of dumping site
includes construction toe wall or retaining wall around dumping site, construction of drainage
system, fencing, compacting spoil etc. Management of spoil also includes the reducing and
reusing the spoil within generated site. Thus, the impact due to waste, spoil and muck is
expected to be direct, medium in magnitude, medium term and local during construction period.
5.1.1.8 Labor camp operation and waste generation
Waste generate from labor camp may also create adverse effect existing environment.
Activities in labor camp can pollutant the nearby water bodies and agriculture land. Similarly,
unsanitary waste disposal practices can create unhygienic environment around the camp. All
the labor camps are proposed on cultivation land hence it degrades quality the agriculture land.
During construction period about 1200 labors including technical person are likely to work in the
project. Congestion of labor force can create problem of sewage disposal and solid waste
management particularly during the peak construction phase. On average in Nepal, solid waste
generation is reported to be about 317 g/capita/day. Assuming 85% labor will be from outside
the project site, solid wasted likely to be generate from camp site will be order of 325 kg/day.
The waste composition analysis shows that highest fraction is organic matter (66%), followed
by plastic (12%), paper and paper product (9%), glass (3%) and other (10%).
Thus, the impact due to labour camp operation is expected to be direct, medium in magnitude,
medium term, and site specific during construction phase.
5.1.1.9 Impact on Natural Drainage, spring and Other Water Resources
Due to the construction of project components, nearby water resources may degraded and
water availability may be decreases. During tunneling, the existing spring and other water
resources along the alignment would cause the leakage of water through the tunnel, resulting
problem for construction and reduced spring water for settlement. Construction of road may
also degrade existing natural water resources.
Presence of spring and major water resource of were not identified along the alignment of
access road and tunnel line. As tunnel will be lying at great depth from the surface, seepage
into the tunnel is not expected to lower the surface groundwater adversely.
The disturbance in natural drainage can be expected in the construction of road. The natural
surface flow of water are broken and diverted during construction of road. The natural flow of
water, which is blocked and diverted on either side, may create soil erosion and land instability.
The flow of water will be well manage before channeled to natural water bodies.
Thus, the impact is direct in nature, low in magnitude, site specific and short term during
construction phase.
Andhikhola Storage HEP (180 MW) Environmental Impacts
EIA Report 5-5 NEA-ESSD
5.1.1.10 Blasting and Bunker operation
Project need explosive and blasting operation during construction of project. Storage and
handling of explosive is risky and needs high-level attention and involvement of security
agencies. Army camp with bunker houses is proposed at construction yard for the safe storage
of explosive and detonators needed for the project. The site for army camp with bunker house
is proposed nearby the intake site.
Blasting during excavation works may affect in the stability of the surrounding area and nearby
air and noise condition due to which local people and wild life may be affected. In overall, the
expected impact is direct, medium in magnitude, site specific and short-term in nature.
5.1.2 Operation Phase
5.1.2.1 Impact on Topography
A construction of dam will create impounded reservoir resulting change in existing scenario to
water pool area. The proposed project will generate electricity throughout the year and there
will be fluctuation in water level ranging from 700 masl to 623 masl. Thus, the visual landscape
of Andhikhola riverine will be change during operation period.
In powerhouse area and access road site, the impact on topography is expected to medium.
Considering overall significant of project the impact on topography during operation phase is
expected to be direct in nature, high in magnitude, site specific and for long term.
5.1.2.2 Impact on Land use
The permanent land acquisition for the project is estimated to be about 913.001ha that will be
utilized for different purposed. Major land use change will occur along the valley of Andhikhola
River.
a. Reservoir Area
In reservoir area, the land use change is occur in 244.016 ha agriculture land, 412.903 ha of
private barren land (kharbari), 60.658 ha of built-up area 11.969 ha forestland and nearly
161.469 ha in riverine flood plain. All these land use changes brought by the construction of
reservoir are permanent land use changes. Existing agriculture land will be converted into
uncultivable land cover by water surface. Hence, loss agriculture in productivity of expected to
be high. Similarly, clearing trees of private barren land and forest will also bring change in land
use.
b. Permanent Camp Area
Permanent camp area in powerhouse site is proposed in agriculture land. Land use change is
expect, as agriculture land will be converted into uncultivable camp area. Total 5.252 ha (4.373
ha agriculture land and 0.873 ha private barren land) is expected to change during
implementation period of project.
c. Land used by other Project Component
Land use by surge shaft, switchyard and access road to powerhouse and dam site are the
other areas of permanent land use changes. Similarly, muck disposal sites are other area of
permanent land use change. Surge shaft, switchyard and access road is expected to bring
change in 5.73 ha agriculture land and 2.90 ha in private barren land.
Muck disposal area, stockpiling area, quarry site, batching plant and crusher plant area that are
temporary in nature is expected to bring changes in approximately 22.43 ha agricultural land
Andhikhola Storage HEP (180 MW) Environmental Impacts
EIA Report 5-6 NEA-ESSD
and 22.78 ha in private barren land. Hence, loss in agriculture productivity and ground
vegetation is expected to be high.
Considering the overall observations in land use, the impact on land use will be direct, high in
magnitude, long term in nature and site specific.
5.1.2.3 Impact on Air and Noise Quality
During operation phase, there will be better available of various facilities, job opportunity in the
project area. With the increase in opportunity and population, movement of vehicle and traffic
density is expected to increase. As a result, air pollutants and noise emission from vehicles
movement and human activities is increase. The nature of the impact will be direct, medium in
magnitude, long term and local.
5.1.2.4 Impact on Water Quality
a) Andhikhola River
In operation phase there will be impounded reservoir after construction of dam across the
river. In the reservoir area, every year there will be cumulative accumulation of sediment. This
will results in increasing the turbidity, suspended solids, dissolved solids and BOD with in the
reservoir area than in present condition.
On both sides of Andhikhola at uphill side, there are settlements and these settlements are
likely to growth after the construction of reservoir. During this operation period, frequency of
movement and activities of people will also increase. Improper solid and liquid waste
generated by people, directly or indirectly will degrade the quality of water. Thus, the impact on
water quality will be direct, high in magnitude, long term and site specific.
b) Kaligandaki River
In operation phase, tail water from the powerhouse goes to Kaligandaki River. As sediment will
settled in Andhikhola reservoir, water used for power generation is expected to be sediment
free. Hence, tail water from powerhouse is likely to have lower sediment concentration than in
present condition. Moreover, permanent powerhouse camp area is proposed at left bank of
Kaligandaki River that will result in increase of population and movement of people. Improper
solid and liquid waste generated by people, directly or indirectly will degrade the quality of
water. Thus, the impact on water quality will be direct, high in magnitude, long term and local.
5.1.2.5 Impact on Hydrology and River Morphology
a. Upstream of Dam axis
During operation period, water will be stored behind the dam and there will be fluctuation of
water level from maximum operating level at 700 masl to minimum operating level 623 masl.
The morphology of river will change due to cumulative accumulation of sediment every year.
The velocity of flowing water will decrease as it approaches near to reservoir outer line hence,
there will be accumulation and deposition of sediment on the outer line of reservoir. Thus,
present morphology of river will be change during operation period of AKHEP.
b. Downstream of Dam axis up to the confluence of Kaligandaki River (Present
Condition)
The downstream release is set as 10% of the minimum monthly average inflow available, which
is equal to 0.31m3/sec. Hence, there is change in hydrology of river system up to the
confluence of Kaligandaki River.

During operation phase of project, water from Andhikhola will be retain behind the dam. The
contribution of water from Andhikhola will be reduce throughout the year and only 0.31 m3/sec
is available; hence, there will be change in hydrology of the section.

d. Downstream of proposed tailrace
During operation period, water used for generation is discharge into Kaligangaki River
through tailrace tunnel. The addition of water to the normal flow of Kaligandaki during dry
season will bring change in hydrology of the river. During operation phase, hourly fluctuation
of water is expected in Kaligandaki River at Downstream of tailrace. Table 5-1 shows the
flow of Kaligandaki River during operational and non-operational hour of proposed project in
operation phase. Similarly, figure 5.3 shows the hourly variation of water flow during
operation period on March. The flow of river is expected to increase by 88% than normal
flow at just downstream of tailrace during operation hours of project.

Impact due to addition of water in Kaligandaki River(Dowenstream of Proposed project)
Discharge in Kaligandaki River provided by project (AKSHEP) shows that 2 years and 5 years
return period flood is about 3800 m3/s and 4980 m3/s. During normal period of year, when
discharge of 73 m3/s from proposed hydropower is added to Kaligandaki River, maximum flow
is expected to be about 1353.25 m3/s which is less than 2 years return period of Kaligandaki
River. Thus, Kaligandaki River is one of the major river with wide watercourse; it can withstand
73 m3/s discharge from the proposed project. Hence, it is expected to have considerably low
impact in river morphology and hydrology at downstream of tailrace.
5.1.2.6 Impact on Soil Erosion and Land Stability
a. Effect of drawdown of the reservoir Reservoir Rim Failure
When a reservoir will filled with water, the ground water table re-establishes itself to a new level
around the reservoir rim. This change and the submergence of slopes may cause the slope to
be less stable than they were previously. Drawdown of the reservoir during operation period
usually results in instability of susceptible slopes.
Andhikhola Storage HEP (180 MW) Environmental Impacts
EIA Report 5-9 NEA-ESSD
Colluvium and alluvial deposits cover the surface of the slope along both side of Andhikhola
River. Some major and minor landslides are presence along both side of River. The rise and fall
of the reservoir water level from FSL (700 masl) to MOL (628 masl) annually, saturate the loose
deposits when reservoir is filled and dehydrate when the water level drops. This alternate
varying condition in soil mass brings structural weakness leading to the failure of slopes around
the reservoir rim. The water wave actions of the reservoir can cause physical erosion and
caving on the slope making there slopes further unstable. Thus, the impact on reservoir rim
stability will be direct, high in magnitude, long term, and local.
b. Land stability of Highway Section
The level of Siddhartha Highway was observed to be around 713masl near Galyang bazaar.
Since the full supply level of reservoir is 700masl and valley side slope of road is steep at this
section, there is probability of landslide and erosion. Thus, the impact on stability of highway
will be direct, high in magnitude, long term, and local.
c. Reservoir Sedimentation
Reservoir sedimentation is the gradual accumulation of the incoming sediment load form the
river. The deposition of sediments depends on the characteristic, geology, and stability of
stability of the catchment area. The average annual sediment load estimated in the AKSHEP
reservoir is about 0.34 tonne/yr. The following potential outcomes are linked to reservoir
sedimentation:
• Stability of the deposited sediment
• Changes in reservoir bed level aquatic ecology
• No contribution to flood plain siltation and fertilizer at downstream
• Change in river dynamic and erosional capacity
• Reduction of nutrients input to downstream zone
• End of useful life capacity of reservoir
Thus, the impact on reservoir sedimentation will be direct, high in magnitude, long term, and
local.
5.1.2.7 Impact due to Solid and liquid Waste
In operation phase, there will be more movement of people than present condition. Improper
management of waste generated by people, directly or indirectly will affect the present existing
environment and natural resources. Thus, the impact will be direct, low in magnitude, long term
and site specific.
5.1.2.8 Impact on Physical Infrastructure
During operation period of project, infrastructures lie within the reservoir area (at 700 masl) will
be submerged. IPP owned Andhikhola HEP with capacity of 9.4MW; two numbers of reservoir
tank also bear impact from project. Regarding to road, paved road in Tallo-Galyang and
unpaved road in Devithan, Sera, Illunga and Bayatari will be effected.Two motorable bridges
and thirteen number of trail bridges will be submerge by the project resulting effect on
movability and accessibility of local people. Thus, the impact on physical infrastructure will be
direct, high in magnitude, long term and local.
5.1.2.9 Impact in Micro-Climate
Reservoir area
A change in water available for evaporation can change humidity and temperature and other
aspect of climate system.There will be an increase in the humidity due to evaporation from the
Andhikhola Storage HEP (180 MW) Environmental Impacts
EIA Report 5-10 NEA-ESSD
reservoir, and a decrease in the average maximum temperature in the summer season as well
as a rise in the average minimum temperatures near the reservoir. When the temperature cools
down especially during the night, fog may be formed around the reservoir area.
5.1.2.10 Emission of GHG and Global Warming
A study by the Deemer et. al. 2016, pointed out that artificial reservoir created by dam is distinct
from natural system in a way that may enhance greenhouse gas (GHG) emissions. The
potential of GHG emission from the reservoir projects is high for projects located in the tropical
region compared to those located in the temperate region. The other determining factor for the
emission of GHG relates to the temperature regime of the atmosphere and reservoir water
body, organic matter present in the reservoir inundation zone and input of organic detritus as
sediments in the reservoir.
The reservoir of Andhikhola Storage HEP is located in sub-tropical zone, it is therefore
expected to emit GHG. In reservoir area, nearly 2.34% of the land area covers by forest,
27.39% of land area by agriculture and 46.34% of land by private Kharbari. The concentration
of the GHG emissions in the initial period will be governed by the amount of organic vegetation
left for inundation under the reservoir. In later periods, the emission levels will depend on the
organic load in the sediment flux and vegetation colonization annually in the reservoir
drawdown zone.
With the present level of study, quantitative estimate of emission of GHG from the proposed
Andhikhola reservoir is difficult but it can be expected that emission of GHG from the reservoir
is high potential of Methane (CH4) emission and Carbon dioxide (CO2) if the area is allowed to
inundate without removal of the organic vegetation.
5.1.3 Impact on Water User
5.1.3.1 Upstream Water user:
The main upstream water user is existing hydropower and irrigation system associated with it.
The reduced level (RL) of existing hydropower weir is at 630.8m and full supply level of
proposed Andhikhola storage HEP is at 700m. Hence, headwork and intake structures of
existing hydropower will be inundated by the reservoir of proposed AKSHEP. The loss on
investment, electrical energy and irrigation facilities associated with existing hydropower will
bear impact due to operation of proposed hydropower project.
The Irrigation system associated with the Andhikhola rive has been managed by Andhikhola
Multipurpose Water User Association (AKWUA). Its command area is about 500 ha in Syangja
and Palpa district which has 5MT per ha of rice production. In addition, maze in wheat also
have good productivity in the region. The region is also the belongs to Potato Zone. Farmers
have been growing different verities of seasonal and off-seasonal vegetables and supply to the
market.
Thus, the impact on upstream water user due to implementation of proposed project will be
direct, high in magnitude, long term and local.
5.1.3.2 Downstream Water User
Downstream of Dam site: The major downstream water user immediate to proposed dam site
is Kaligandaki ‘A’ HEP. It will receive reduced amount of water than in present condition due to
the implementation of proposed storage project. Present contribution of water from Andhikhola
to Kaligandaki ‘A’ HEP and reduced flow of water at downstream of proposed dam site during
operation of storage HEP is calculated and shown in table 5-1. Though, flow of water seems to
Andhikhola Storage HEP (180 MW) Environmental Impacts
EIA Report 5-11 NEA-ESSD
be a less in comparison to the discharge of Kaligandaki River (Table 4-8), the effect of reduce
flow is measurable and significant in long course of time, hence its impact needs to be
considered. Thus, the impact on downstream of dam site water user ( Kaligandaki ‘A’ HEP) due
to implementation of proposed project will be direct, long term and regional. The table shows
the reduced amount of water during operation phase of Andhikhola Storage HEP..

hydropower and downstream release water from headwork of existing Andhikhola HEP. These values
are current contribution of Andhikhola to Kaligandaki ‘A’ HEP
Downstream of Powerhouse Site (D/S of Tailrace):
The proposed project collect water of wet season and discharge it in controlled way throughout
the year during operation hours. Gandak HEP, which is at the downstream of proposed
powerhouse site will receive additional amount of water (73.0 m3/s) during dry season. Gandak
Power house can generate additional energy during dry season, which is positive impact due to
the implementation of proposed project. Thus, the impact on downstream of powerhouse site
water user (Gandak HEP) due to implementation of proposed project will be direct, medium in
magnitude, long term, and regional. The Table 5-3 show list of projects in downstream of the
project area.

5.2 Biological Environment Implementation of AKSHEP will affect the existing ecosystems in the project impact area multi-
dimensionally and the effects may be both adverse and positive. The major impacts on the
biological environment will include the loss of individual trees and loss of vegetation cover due
to site clearance and reservoir formation; increased demand of fuel wood and timber; impact on
NTFPs; habitat loss of mammals, bird and reptiles because of change of vegetation cover and
site disturbances
5.2.1 Construction Phase
5.2.1.1 Forest/ Vegetation Loss
a. Community/Government Managed Forest
As far as standing trees are concerned, based on the field study and total enumeration taken
during EIA, 8192 number of trees including poles of 19 different species are estimated to be
felled during project construction period. The pole-sized trees are 12.2%, whereas mature trees
are 87.8%. Acacia catechu and Shorea robusta are found to be the dominant species in the
project impact area. Loss of tree and pole in different forest is presented in Table 5-5.

Proposed AkSHEP will permanently acquire 17.765 ha of forestland. Of the total forest area
lost, two-community forest will lose 10.725 ha forestland and Government forest will lose
remaining.
b. Private tree (kharbari)
Based on the field study and sample survey taken, 442.665 ha private unarable (Kharbari) will
be lost by project facilities. In particular, 412.903 ha of private unarable (Kharbari) will be
inundated by reservoir. It is estimated that, about 335.980 ha of Kharbari will be lost
downstream of the Galyang bazar and about 76.923 ha of Kharbari will be lost upstream of the
Galyang bazar by inundation. Potential loss of trees on different components of the project on
private land is given in Table 5-6.

In addition to that, 7668 trees from the agricultural land including fruit tree within the reservoir
area will be lost due to inundation. So In total 221411 private trees will be lost.
Impact of the project on vegetation of Community/Government forest will be moderate, local in
extent and medium term in duration. However, vegetation loss from the private unarable
(Kharbari) will have high impacts on local economy. Large number of fodder tree and
economically valued trees from the private land will be lost. Local people also losses fodder and
grass base permanently. This will have site-specific impact for a long duration of time. This loss
of forest and vegetation cover might create indirect impacts resulting in the degradation of the
hill environment for a long duration. The following table provides the detail of tree loss
according to project component.

Andhikhola Storage HEP (180 MW) Environmental Impacts
EIA Report 5-17 NEA-ESSD
5.2.1.2 Changes of Demand for Fuel Wood and Timber
Altogether 8192 individual trees from both GMF and CF will be felled during the construction
period. Fuel wood and timber thus produced will help to meet the local demand during the
project construction.
The existing private trees in Kharbari are enough to support the demand of firewood and timber
to the dependent HHs. However, cutting down of 221411 standing trees in private land is
significant to the livelihood of local people and is direct and long-termed. The economic impact
will be significant because timber and firewood obtained from the felled trees can be sold in
local markets within existing legal framework.
In addition, there will be large number of workforce in the area during the project construction
period. Even though most of the labor force will be from nearby areas, there will be large
number of people from outside the project area for the project construction. Due to this, the
increase in demand of fuel wood and timber during the construction period is expected to be
high.
Similarly, the influx of construction workers can increase the possibility of fire hazard to the
local forest. This is more specific in those temporary labour camps, which will be, during the
construction phase, located near the forest. The improper handling of firewood or cooking fuel
can induce such impact. However, most of the project area lies in private land and such labour
camps will be kept in close monitoring by the local people, so the impact will be low in
magnitude, site specific and short-termed.
5.2.1.3 Possible Encroachment of nearby Forest
The proposed project requires large area of land. Though, location of various project facilities,
material storage yard, camp site, etc. have already been proposed, there may be chances of
encroachment of nearby area for the labor’s ease. Forest and nearby areas possibly be
encroached for small scale stone quarry, onsite material storage, short-term migratory labour
camp, etc.Impacts of the project on the nearby areas will be of low magnitude, extent will be
local and last for medium period of time.
5.2.1.4 Exploitation of Non-Timber Forest Products (NTFPs)
Most of the area of the AKSHEP lies in the private land. According to the locals, the availability
of the high value medicinal plants in the project area is limited. Therefore, there will be little
chances of collection of NTFPs and medicinal plants by the labour force from the project area.
However, unauthorized access of labour force in the private farm and collection of fruits and
vegetable may happen. Regarding the forest/local products besides firewood and timber,
involvement of the workforce in exploitation of NTFPs and other private resources is not
expected due to the presence of local community. The magnitude of impacts is considered be
low, extent is site specific and duration is short-term.
5.2.1.5 Habitat Loss and Fragmentation
During the project construction period, all trees within the reservoir including free board level
will be completely lost. Tree, poles and ground vegetation within 965.821 ha (Total land
requirement) land will be cleared. This will destroy the existing forest ecosystem, river
ecosystem and cultivation ecosystem of the region. So all the habitat components of wild fauna
including birds and insects will be lost. Distances between two forest patches in the left and
right bank of the river will increases. It will also hinder movement of wild animals from two forest
patches.
Andhikhola Storage HEP (180 MW) Environmental Impacts
EIA Report 5-18 NEA-ESSD
Though all the vegetation in the area will be cleared, there are no prime habitat of the wildlife in
the impact area. The impacted forest areas are occasionally used by the wildlife as feeding
ground. Hence, impact on wildlife due to habitat loss is less prominent. Direct loss of wildlife by
the land use change is not expected. In addition, most of the project area is on the private land,
impacts of the project on habitat loss and fragmentation is predicted to be of low magnitude,
extent will be local and last for long period.
5.2.1.6 Possible Hunting and Poaching
In view of the availability of the wild fauna in the area, there is littlepossibility that illegal hunting
and poaching may occur in the area. The powerhouse area is the only possible area of
potential wildlife poaching because powerhouse is located in the forest area. Due to its
geographical location surrounded by settlements, availability of wild fauna and its poaching in
the area is thoughtful. There may be chances of illegal fishing in the Andhikhola and
Kaligandaki. Both construction workforce and the economic benefit seekers (local communities
as well as the outsiders) may be involved in such activities. The project impact on this is
expected to be of low magnitude, extent will be local and last for short period of time.
5.2.1.7 Impact due to Construction Disturbances
Construction disturbances resulting from blasting, drilling, vehicular movement and other
construction related activities would interrupt normal movement, feeding and other activities of
wild animals. Similarly, night blasting, electric lights in and around the construction sites and the
presence of large number of humans will also affect wild animals. The clearing, excavation,
grading and filling activities will affect less mobile, frequently smaller species of mammals and
other animals. The impact is expected to be moderate in magnitude, local in extent and medium
term in duration.
5.2.1.8 Impacts on Protected Species of Flora and Fauna
Of the total recorded species in the Project area, there is not any protected species of
mammals, birds or harpeto-fauna in the project area. However, some species of mammals and
birds are listed in the IUCN red list and some are on CITES appendixes. So, the impact of the
project on the protected fauna is not envisaged.
Regarding flora, Shorea robusta is the only tree species whose commercial felling,
transportation and export is prohibited under the NPWCA-2029. So, there may be chances of
the illegal felling ofShorea robusta. Both construction workforce and the economic benefit
seekers (local communities as well as the outsiders) may be involved in such activities. The
impacts of this activity is expected to be low, extent will be local and last for short period.
5.2.1.9 Increased Fishing Activities
Fishing activities in the project area will increase throughout the duration of the project
construction due to the influx of people. The labor force and their dependents will be involved in
fishing activities. Harvesting by using simple ordinary techniques will probably not affect the fish
population significantly. However, destructive technique such as the use of dynamites,
herbicides and electric rod will have an adverse impact on the local fish population.
5.2.1.10 Impact on Aquatic Flora and Fauna
During the diversion of water from headwork, some section will be dechannelized. Aquatic
species including macrophytes, aquatic animals, fishes, phytoplankton and zooplankton will be
affected in this section.During this stage the turbidity level of water will be increased. Thus,
downstream flora and fauna will also be impacted. In addition, Accidental spill of oils, lubricants
Andhikhola Storage HEP (180 MW) Environmental Impacts
EIA Report 5-19 NEA-ESSD
and hazardous waste and direct disposal of diverse types of construction wastes, camp wastes
and construction spoils into the water body will affect aquatic lives (flora and fauna) with limited
range of tolerance. So, impact of the project on aquatic life is predicted to be of moderate
magnitude, extent will be local and last for short period.
5.2.1.11 Fire hazards
Before the filling of the reservoir, all the vegetation within the reservoir has to be clearly felled
and removed. It takes some time even some months to clearly felled the vegetated area and
remove all biomass. If the dry biomass after felling cannot be managed properly, or biomass
thus removed from the reservoir cannot be managed properly, there may be the chances of
setting fire to dry biomass.
In addition, the burning of firewood or LP gas in the labour camp and other project areas also
increase the risk of fire hazard. So, fire risk of the project is predicted to be of moderate
magnitude, extent will be local and last for short period.
5.2.2 Operation Phase
5.2.2.1 Changes of Demand for Fuel Wood and Timber
During the operation phase, site-specific and short-term effects such as increase in pressure on
forest resources will settle down. Any pressure on the forest area is not expected.
5.2.2.2 Aquatic Habitat Loss and Fragmentation
After the operation of the dam, hydrology of AndhikholaRiver will be changed. Lotic ecosystem
of the Andhikhola River will be changed into the lentic system due to ponding of reservoir.
Existing shallow water habitat of the aquatic life will be lost. Fish migration will be blocked by
dam. Five long distance migratory species: Anguilla bengalensis, Bagarius yarrelli, Clupisoma
garua, Tor putitora, and Tor tor, will be impacted by the dam construction. In addition, the
reservoir create barrier for migration of wild animals between two banks of the Andhikhola river
valley.
In the downstream region of the Andhikhola River, Dam of the project check sediment and
nutrient loading by floodwater thereby removing the bottom level of food web and aquatic
habitat. However, there is Kaligandaki HEP dam within 2 km downstream of the proposed dam
site of AKSHEP. In comparison to Andhikhola, flow in the Kaligandaki River is very high. The
span of reduced flow region is just about 2 km. Therefore, impacts of the project on the habitat
loss and fragmentation will be of moderate magnitude, predicted for a long time in a local
extent.
5.2.2.3 Changes in Number of Fish Species and their population
High dam across the river will change the hydrological regime and hinder the migration and
other behavior of fish and other aquatic animals. This will block the seasonal flux of fish species
upstream and downstream of the river. Operation of the dam changes the river ecosystem from
lotic to lentic and thereby fish and other aquatic life species. In the upstream of the dam,
numbers of migratory and shallow water fish species will be reduced and aquatic community
will also be changed. In contrary, there is possibility of flourishment of new aquatic communities
adopted to deep-water bodies. Therefore, the Impact of the project on the fish species and
their population will have moderate impacts for long period.
5.2.2.4 Fire hazards
Fire may caught-up in the powerhouse facilities due to short-circuit. Otherwise, no any fire
hazard is anticipated during operation phase.
Andhikhola Storage HEP (180 MW) Environmental Impacts
EIA Report 5-20 NEA-ESSD
5.2.2.5 Changes in River Ecosystem
Construction of dam and its operation will alter the river ecosystem.The fundamental changes
occurs in the three regions:
a. Upstream of the Dam (Reservoir Area)
As the dam of the project comes in operation and reservoir fills, lotic water system changes into
the lentic and existing ecosystem will be inundated. Flora of the inundated area will be
completely lost and fauna will be migrated to another area. Existing habitat of aquatic life: in-
channel and flood plain wetland, pool and riffle, will be lost. Many other changes like; changes
in water temperature and quality, changes in thermal regime, land-water interaction and
changes in water productivity and sediment transport are obvious but difficult to predict. All
these changes have long-term implications on fish and aquatic fauna of Andhikhola River. So, it
is predicted that, the impact of the project on the river ecosystem upstream of the dam area will
be of high magnitude, last for long period of time in that particular area.
b. Downstream of the Dam (Reduced Flow Zone)
As the dam of the project comes in operation, flow in the Andhokhola River will be regulated
throughout the year. The downstream flow of the river will be 10% of the minimum monthly flow
available, which is equal to 0.31m3/sec. The regulated flow drom the results in complete change
in the river hydrology and ecology up to Kaligandaki confluence, dewater zone of the project.
The impact of change in river hydrology and ecology is very complex, therefore very hard to
quantitatively assess.
In qualitative terms, this will affect both on floodplain wetland and in-channel wetland. In
absence of flooding, usual vegetation in the flood plain will not grow. Dam also prevent the
nutrient loading in the river by the flood. As the dam-trapped sediment from the upstream of the
river, the bottom level of the food web is removed, which means loss of nutrient and habitat for
many aquatic species (Lin, 2011). Considering the fact that, the Kaligandaki confluence of the
river is within the 2km downstream of the dam and flow in the Kaligandaki is very high compare
to Andhikhola, the impact of reduced flow will be significant only upto Andhikhola-Kaligandaki
confluence. So, the impact of proposed hydropower in the downstream of the river will be low,
last for longer period of time and extent will be site specific.
c. Downstream of The Powerhouse (Augmented Flow Zone)
The powerhouse of the proposed project releases water to the Kaligandaki River through its tail
race. During operation hour, about 73-cumec water will be added to the Kaligandaki River.
From December to May, the power house will operate for 8.25 hrs, a significant tailrace flow to
Kaligandaki River will be expected. There exists complexity in the prediction of impacts of
possible anoxic and nutrient rich water, consequences of potential temperature differences
between Kaligandaki and tailrace water, impact on Kaligandaki riverbed due to sediment free
water release, and others.So, the impacts of the AKSHEP on the Kaligandaki river ecosystem
is expected to be moderate, extent will be local and the last for long period.
In contrary, addition of about 73 cumec of sediment free water in the Kaligandaki Rriver will
have significant beneficial impacts on the aquatic ecosystem of Kaligandaki River.
5.2.2.6 Alteration in Nutrient Level of Andhikhola River
Construction of dam and trapping of sediments and nutrients in the reservoir-upstream of dam
will change the nutrient level in dewater zone. Nutrient loading during high flood period in
downstream region will also be checked. So, nutrient deficiencies in downstream region as well
Andhikhola Storage HEP (180 MW) Environmental Impacts
EIA Report 5-21 NEA-ESSD
as eutrophication in the reservoir is anticipated as an impact of dam. However, stretch of
dewater zone (upto Kaligandaki-AndhiKhola confluence) is short (about 2 km) from the dam of
Andhikhola and flow in Kaligandaki is very high compare to Andhikhola, impact on nutrient level
downstream anticipate to be low, local and long term in duration.
5.2.2.7 Thermal Pollution
Thermal stratification in the reservoir water can lead to change in temperature in augmented
flow zone near the tailrace of PH. This thermal pollution will affect aquatic life.
5.2.2.8 Safety and Movement of Animals
The proposed AKSHEP planned to provide energy at peak hour. During its operation hour, it
releases about 73 cumec of water to Kaligandaki River through its tailrace. Sudden addition of
such volume of water in Kaligandaki during dry season will be significant. In addition,
Kaligandaki HEP also add significant volume of water during peak hour through its tailrace to
Kaligandaki. Both the tailrace of Kaligandaki and Andhikhola are within few kilometers. The
cumulative volume from both the tailrace will be significant to the Kaligandaki River during peak
hour in dry season. Such variation in flow level in Kaligandaki will risk the safety and movement
of domestic and wild animals as well as human beings. This impact is predicted to be
moderate, extent will be local and last for long duration of time.

5.3.1.4 Impact on Livelihood of PAFs/SPAFs
The construction of the proposed project will affect livelihood of the people of more than 10
settlements of reservoir area. The main source of livelihood of PAFs is agriculture. People of
the area grow paddy, wheat, potato, beans and some also farm orange in their field. By selling
these entire food and fruit item, they survive their livelihood. Livestock rearing is another major
source of income for the people of the area. Thus, subsistence farming and livestock rearing
are the main occupation for the people of the project area. Some household head of the project
area also go the foreign country to earn some money for their livelihood. The farming pattern of
the project area is common as other hilly area of Nepal.
The construction of the proposed AKSHEP will affect or destroy their farming pattern and so
their livelihood. As the farming area and the kharbari land will be filled with water, their source
of income and the basis of livelihood will also demolished. These families will cope with the
positive as well as negative impacts due to construction of the project. The impact is direct in
nature, moderate in magnitude, local in extent and long term in duration.

5.3.1.5 Pressure on Existing Facilities, Services and Resources
Construction of the AKSHEP is scheduled to take place in 82 months. About 1200 workers with
different levels of skills will be working in the project during this period. There will be increased
pressure in social service and facilities due to the migrant work force and outsider’s population.
Apart from the migrant workforce, during construction period, there may be influx of outsider
population aiming to make trades and businesses in the project area. Such outsiders may come
along with their families. In this way, the population of a relatively smaller project area can
become crowded with addition of the outsiders. The addition of the outsider population creates
pressure in social service providing institutions in the area.
Andhikhola Storage HEP (180 MW Environmental Impacts
EIA Report 5-28 NEA-ESSD
By experience of hydropower projects construction in Nepal, it is anticipated that pressure on
the social service institutions particularly educational facilities, health services, water supply
systems and above all the sanitation management of the area will be created during the
construction period of AKSHEP. Its consequences might be shortages of rooms, benches,
teachers in the nearby schools; shortages of medicine, and medical personnel in nearby health
posts; shortages in water supply; increase in thefts, quarrels over resources and above all
increase in solid waste, human waste and degradation of the overall sanitation status of the
area. The impact will be indirect in nature, moderate in magnitude, site specific in extent and
short term in duration.
5.3.1.6 Occupational Health and Safety Hazards
Construction workforce, especially the laborers are susceptible to injuries and diseases.
Workforce involved in new slope cutting will be exposed to typical health hazards. Laborers
involved in structural works will also encounter risks. Personnel involved in handling of fuel,
lubricants and hazardous material have risks of facing health hazards. In the same way,
working in tunnel construction will always risky. There is the possibility of encountering
poisonous gases, rock burst and groundwater flow inside the tunnel. The construction of
headwork, siphon crossing and other structures involves concrete mixing, concrete pouring,
reinforcement banding/ installing, steel ribs fabrication and welding.
The workers working with concrete may be exposed to fine silicate particles that might cause
lung diseases. Working in dust, tree felling, spoil tipping and quarry/crushers will also pose
serious risk to the laborers. Poor drinking water, lack of hygienic environment in labor-camps,
unmanaged work-camps and haphazard stockpiling are the major areas that will increase the
chances of the workforce being exposed to health risks. Potential impacts to health are
respiratory diseases, eye infections, dysentery, diarrhoea and cholera. The impact is of direct in
nature, moderate in magnitude, local in extent & short term in duration.
5.3.1.7 Impact on Houses, Settlements and Social Infrastructures
There are more than 10 settlements in the reservoir area and one settlement near to surgetank
area. Altogether 1611 private structures (houses, cowshed, kitchen, toilet) and 25 public
structures (public buildings, suspension bridge, schools, and others will be affected (Table 5-17
and Table 5-18). will be impacted due to project activities and thus relocated to any other
place.The magnitude of impact on above mentioned private and social infrastructures are high,
extent is local and duration is long term.
5.3.1.8 Damage to houses/structures due to vibration created during blasting
Construction of about 7.5 km long headrace tunnel, underground powerhouse and tailrace
tunnel will require huge quantity of blasting. Since, there are no any settlements near to
headrace tunnel, the impact of vibration created during blasting is not seen. During blasting,
energy released may result in shaking of the ground and structures built over the ground which
may damage the structures in the form of cracks and in the worst case, collapse of the entire
structure, if it is weak. Though the spread area is not extensive, the impact being related to loss
of life and property; magnitude is considered high, extent is local and duration is long term.
5.3.1.9 Impacts on Communal Resources
The outside workforce might use the community (ethnic groups) resources such as water,
forest products, and may use other resources used by the communities. Their use of the
resources will increase competition with the local communities and in the degradation of the
resource base particularly the water and forest resources. About 2000 workforce will rely on
Andhikhola Storage HEP (180 MW Environmental Impacts
EIA Report 5-29 NEA-ESSD
health service, drinking water, school and such other resources of the project area. Therefore,
these communal resources located in project area will have to serve the increased population
(during construction) with their limited resources. Similarly, there will be extra pressure in the
existing drinking water sources when used by the construction workers and their dependents.
The envisaged impacts are local, short duration and moderate in magnitude.
5.3.1.10 Impact on local Infrastructures, People's Mobility and Transportation pattern
The construction of project will involve transportation of significant quantity of construction
materials from outside and within project area. Number of skilled, semi-skilled and unskilled
work force will migrate to the project area. The increase vehicular activities will increase the
dust level released from the dust road of the project area. Similarly, the increase traffic is also
likely to increase the accidental events in the project area.
The project activities will also add an extra pressure on various existing infrastructures of the
project area. The existing road and the suspension bridge of reservoir area will have the most
impact. At the same time, the increased traffic due to project activities will affect the normal
movement pattern of local people and tourists. Despite these adverse effects, increase in traffic
volume will provide the people with easier access to the area. The magnitude of impact is
considered high, extent is local and duration is long term.
5.3.1.11 Degradation of Agricultural Land
The project will permanently require about 780 ha of private agricultural land located in the
project area. Moreover, the project will also lease 52.82 ha land for temporary use. During the
preconstruction stage these land will be prepared for the setting of construction camps,
construction equipment and parking of the construction vehicles. These activities will degrade
the agricultural land. On the other hand, the setting of construction vehicles and equipment will
hinder the agricultural production and hence its productivity. Considering the direct impacts on
PAFs, the magnitude of the impact is rated high, extent local and duration long term.
5.3.1.12 Gender and Vulnerable group
Household survey of the PAF reveals that significant numbers of indigenous and Dalit
population exists in the project area (49.7% of total population; 40.2% indigenous, 9.2% Dalit
and 0.3% Muslim). Therefore, the permanent and temporary land acquired by the project, and
the direct and indirect action of the project is thus going to impact the large numbers of
indigenous and vulnerable people as other groups. The literacy rate of the women of the
project area is lower (67.8%) then male. Similarly percentage of female members attending
higher education is also lower then male.
During the project construction, daily wages labor will be deployed for excavation,
transportation of construction materials and other construction related works. The contractor,
especially the sub-contractors, may discriminate the women and vulnerable group while hiring
the worker. There will be potential of the exploitation of the female members by the construction
workforce, mostly the outside workforce. It is assumed that most of the labor force required for
the project will be farmers and landless people from the vicinity of the actual work place moving
around the construction place as the construction proceeds.
The impact of the project construction is also expected on the poor and disadvantage people
who might be directly not affected by the project but affected in other ways such as price hike,
shortage of consumable goods, social inferiority and less opportunity of project related benefits.
Considering the nature of construction work and manpower employed, the magnitude of impact
is considered to be low, the extent is local and the duration is short termed.
Andhikhola Storage HEP (180 MW Environmental Impacts
EIA Report 5-30 NEA-ESSD
5.3.1.13 Transmission of Communicable Diseases
During project construction, large numbers of outsiders as skilled, semi-skilled and unskilled
workers will migrate to the project area. These temporary migrants may carry different
communicable diseases. The diseases might spread to the local people of the project area
through different modes of transmission such as air, water and food contaminated by the
carriers. At the same time, the foreigners and people from different parts of country will visit the
project area for different types of business purpose. These peoples as well as the project staffs
might engage in sexual relationship with the locals.
Therefore, diseases like AIDS, STDs, gastroenteritis, etc. are potential risks to human
inhabitants of this area. The present available health services in the area would be insufficient
to cater health service to outsider workforce in the project area. Considering the nature of
impact, its magnitude is moderate, extent is local and duration is long term.
5.3.1.14 Probable impact due to increase child labor, an accidental risk and disturbance
to the educational pattern
During project construction, large number of local people as well as outsider will be engaged
directly and indirectly to project. Although, the project will have the provision of not employing
children less than 16 years of age, the poor parents around the project area may engage their
children in some form of work like in tea stalls, collection of sand, aggregates, etc. Since there
would be extra earnings, the children will be attracted to help their parents in working with the
project than going to school for education. This will definitely affect educational pattern of
project area. At the same time, different project activities such as drilling, blasting, and other
construction activities pose safety concerns to local people especially children. The impact is
moderate in magnitude, extent is local and duration is short term.
5.3.1.15 Impact on Social, Cultural and Religious Practices and norms/values
Project area is populated by large numbers of ethnic caste group Magar and occupational caste
group Kami. Besides, other caste groups are also residing in the project area. These people
have their own culture, norms and values. In terms of religious belief, the people in the area
follow Hinduism but they widely celebrate other festivals and rituals like Jatra, Rodhi. One
family help other family during farming seasons as 'Parma' (Parma is the social practice where
people do not get money or other assetsfor helping their neighbor; in return their neighbor will
help them in his turn). In this way, all these people live in harmony and in good cooperation
among themselves.
The large number of outside workers belonging to different religious and cultural belief will
interact with local people directly or indirectly and may impose their own beliefs knowingly or
unknowingly which may bring some sort of conflict and unrest in the area. However, the migrant
workers will be mostly from within the country people, the impact is not expected to be
significant. The magnitude of impact is low, local in extent and short term in nature.
5.3.1.16 Religious, Historical and Archeological Site
There are number of temples, religious and cultural sites in the project area. One church and
other religious places located within reservoir area will be affected due to the construction of the
project. The impact is high and long termed in nature.
5.3.1.17 Impacts on local people due to Increase in Economic Activity
Increase in number of people within a small rural area creates more demand of daily
consumable commodities. This will certainly result into price hike in the local market as the
Andhikhola Storage HEP (180 MW Environmental Impacts
EIA Report 5-31 NEA-ESSD
supply fails to meet the demand in the project area. This will have adverse impact on the low-
income people of the area. The project will not be able to employ all local people so there will
be gap in income level between the employed and unemployed. This gap may bring frustration
and anxiety in unemployed people and pride in employed people, thus bringing in social
disharmony.
As the workers and the people who are able to earn through local trade/business will be
earning more, they may gradually develop a habit of spending more. This may be reflected in
the form of gambling, prostitution and alcoholism and such other social evils. The magnitude of
impact is moderate, extent is local and duration is medium term.
5.3.1.18 Law and Order
During the construction phase, the contractor will employ labor from different places belonging
to different socio-cultural background, religion and faiths. Since some of the workers will be
accompanied by their dependents, actual number of people staying in camps may still be
higher. They will interact and interrelate with the project management and with the local
community and there will be possibilities of conflict of interest thus affecting the law and order
situation. Furthermore, cash flow in the area may attract the workers towards gambling, alcohol
consumption, prostitution, stealing, looting, and such other social evil. In such situation general
breakdown of law and crime may occur.
There is are police posts within DIA of the project area. The local conflicts regarding social
crime and quarrels are solved by the local leaders and social activists. The extreme cases are
looked after by the police posts. During the project construction, the available resources in the
district police post may not be sufficient.
Analysis of number of workers, expected behavioral changes, and existing security situation
shows that the law and order situation of the area may be deteriorated if no mitigation measure
is taken. The magnitude of impact is moderate, extent is local and duration is medium term.
5.3.1.19 Impacts of Aesthetics
Changes in aesthetics (landscape/visual beauty) are another potential direct effect from
AKSHEP development. The proposed project can change the visual quality of area by
introducing structures, cables, power-substations, lights and others. They may also produce
sounds during construction, maintenance or normal operation that some people will find
objectionable in recreation settings. Disposal of muck generated during the project construction
will change the existing topographical setting of the project area. Similarly, the structural
location of the project components dam, tunnel inlet portal, tunnel outlet portal, camp house,
powerhouse, and other components will change the natural aesthetic and visual qualities.
Cutting of trees, diversion of water and other project activities will change the landscape quality
of the project area. The magnitude of impact is moderate, local in extent and long term in
nature.
5.3.2 Operation Phase
5.3.2.1 Decrease in Agricultural Production due to Loss of Agricultural Land
The project components are located on private agricultural land, government land, settlement
area and community forest area. Permanent structures of the project such as permanent camps
for powerhouse site and dam site, access road; will require 276.7061ha. of private agricultural
land on permanent basis. During the operation stage these productive agriculture lands will be
Andhikhola Storage HEP (180 MW Environmental Impacts
EIA Report 5-32 NEA-ESSD
occupied by these permanent structures, which will ultimately hinder the agriculture production
and hence its productivity too.
Similarly, there will be farming hindrance during ploughing the agro-fields if the permanent
structures are placed at the middle of any field boundaries. It is likely to occur in the access
road and construction campsite. On the other hand, leakage of oil, grease and other lubricating
liquids from the machinery equipment (like powerhouse, switchyard, transformer, etc.) will
hinder the agricultural production and hence its productivity. However, the land owners will get
a good compensation for acquiring and leasing private agriculture lands as well as for the loss
of agricultural production from the AKSHEP, the impact will be low in magnitude, local in extent
and long termed in duration.
5.3.2.2 Possible Impact due to Sudden Release of Water
a. Downstream of Powerhouse
During project operation period, a maximum of 73 m3/s water will be added to the Kaligandaki
River in the dry season. This will increase the water level of Kaligandaki River. The settlements
along the Kaligandaki River, Palpa District like Hugi will be impacted due to increased level of
water. The sudden release of water in the stream, without any prior information, can lead to
washing away of animals and humans. The magnitude of impact is moderate, local in extent
and for long term.
b. Downstream of Dam
Due to decrease in flow level downstream of the dam in the wet season, activities such as
swimming and fishing in the Andhi Khola River might increase. If the water is released from the
dam to the river for maintenance purpose without any prior information or warning, people may
be washed away. Since the project will release a certain quantity of water (around 10% of
current flow), the flow of water will decrease so far. The magnitude of impact is low, local in
extent and long term.
5.3.2.3 Impact on local people due to decrease in economic activities
With the completion of construction phase, the highly active situation will almost come to a
standstill. Most of the workers will lose their job, there will be drastic decrease in local trade of
foodstuff and daily commodities, cash flow and transaction will decline resulting in overall
slowdown of economic activity. Thus, people who were benefiting from the economic activity
brought in by construction works will face sudden loss, which will create discomfort and anxiety
among them. Nevertheless, it is expected that people will gradually adapt to the changed
conditions within a period of few months to a year. The magnitude of impact is low, local and
medium term.
5.3.2.4 Possible Impact on Gender and Children
After the completion of the project construction, most of the workers and children (if any) will
return to their home and start living their normal life. Since there will be very limited project
activities during the operation phase, no significant impact on women, children and others
vulnerable groups is expected. The overall magnitude of impact is low, extent is local and
duration is medium term.
5.3.2.5 Occupational Health and Safety Hazards
Occupational Health and Safety aspect is one of the likely impacts to be experienced during the
operation and maintenance period of the project. Access to electricity may also bring some
hazard associated to electric shock. Similarly, lack of training on operation and maintenance
Andhikhola Storage HEP (180 MW Environmental Impacts
EIA Report 5-33 NEA-ESSD
skill and unavailability of Personal Protective Equipment (PPE) may also cause risks for human
live. The impact low in magnitude, local in extent and long term in duration.
5.3.2.6 Impact to Downstream Projects
There are many projects operating in Kaligandaki River, downstream of powerhouse with
regular water flow. In the project operation phase, the water level of Kaligandaki River will
increase with additional water flow. This may impact the projects of downstream. The
magnitude of impact is high, site specific and long term in duration.
5.3.2.7 Water Use Rights
The local people normally use water of Andhi Khola for various purpose like, swimming, fishing,
irrigation, as well domestic uses. Some people from Shera settlements were reported to use the
river water for drinking and other domestic uses. In addition, water of Andhikhola is also used
for rrigation and energy generating purpose within the stretch. The impact is moderate in
magnitude, local in extent and long term in duration.
5.3.2.8 Impact on Fishing
Some local people involve in fishing activity in Andhikhola occasionally. however, there are no
any fishing community in the project area. So, the project impact on fishing activities of the
people will be low in magnitude, site specific and long term in duration.
5.4 Beneficial Impacts
5.4.1 Construction Phase
5.4.1.1 Local Employment Opportunity
One of the important beneficial impacts of the project during construction is local employment
generation. The estimated construction period of the project is 82 months. The construction
module, which emphasizes labor-based approach using local people, tends to benefit directly to
the people living in the area. The construction works offers a wide range of employment for
2000 people varying from unskilled to skilled. Of them, most of the unskilled and semi-skilled
persons will be hired locally as per their capacity and qualification.
The socio-economic survey revealed that majority of the affected households are willing to work
in the project and 73.18% of total population are working age population. Thus, local people
can be benefited from various employment opportunities generated during the construction
period. The amount of money that will flow in the local economy in terms of wage earnings will
directly enhance the quality of life of the local people. Therefore, the overall impact will be
medium in magnitude, local in extent and short term in duration.
5.4.1.2 Increase in Local Skills
The project requires about 2000 including skilled and semiskilled human resources. Both of
them should have some technical skills. Of them, most of the unskilled and semi-skilled
persons will be hired locally as per their capacity and qualification. The groups Magar and
Dalits of the project affected area are envisaged to increase the skill level regarding to the
construction activities.
Besides, AKSHEP will also launch training programs in specialized areas such as electro-
mechanical works of hydropower, house wiring and maintenance, road slope stabilization; spoil
handling, metal works, etc. First priority will be given for the project affected people and local
people to the extent they are interested to get involved in construction activities. Therefore, the
Andhikhola Storage HEP (180 MW Environmental Impacts
EIA Report 5-34 NEA-ESSD
overall impact is considered to be moderate in magnitude, local in extent and long term in
duration.
5.4.1.3 Uplift social-life of local people by CSP and skill enhancement trainings
The residents of affected wards, DIA and IIA settlements will be provided support programs in
the field of health, education and drinking water as part of Community support program (CSP)
by the project. The support will be provided based on the study of the requirement and
available resources and is assumed to uplift the social life of local people. The local community
will be consulted in determining these matters. AKSHEP will also provide skill enhancement
training to SPAFs, who have lost more than 50% of their agricultural land, for their capacity
building and restore their livelihood.
During the project operation, the project will establish at least one health care unit either at
headworks or at powerhouse area. The better electrification will further enhance the facilities
available at the centers. Similarly, AKSHEP will provide some assistance to the needy local
schools. This will help to improve the overall quality education of the project area
RMs/municipalities. The overall impact is considered to be moderate in magnitude, local in
extent and long term in duration.
5.4.1.4 Business Opportunities for Locals and Increase of Economic Opportunities
Project requires about 2000 people as construction workforces during the construction period
over 82 months. With such huge numbers of workforce (labor groups, construction crew and
project team) and visiting population, there will be an abrupt rise in the demand of local
agricultural products. The workforce who will reside at different locations of the project area for
the construction period will depend on local market for their day to day consumption goods.
They will require a variety of service facilities and consumer goods produced locally as well as
from outside of the project area. Fresh vegetables and fruits, milk and milk products produced
locally will be in high demand. The local farmers of the project area producing these products
will, thus, be benefited. The establishment of the new market place and expansion of the
existing markets will have positive impacts on the local economy.
Tea shops, grocery shops, restaurants, fast food will be the major source of income to the local
people. Besides, other micro and small industries such as dairy, poultry and livestock farming,
furniture, tailoring, handicrafts production, etc. could be established by the local people
themselves to meet the requirements of the construction workforce. The project will incorporate
programs to assist the local farmers in the commercial production of local agricultural produces
by training, distribution of improved seeds and technology transfer. The local people having
some experience in running lodges, restaurants and grocery shops will open the enterprises
and create employment opportunities to themselves and others. As a result, there will be a
significant cash flow in the local economy. Therefore, the overall impact will be indirect in
nature, moderate in magnitude, local in extent and short term in duration.
5.4.1.5 Revenue Collection Opportunities for Local Government
The proposed AKSHEP will require significant amount of construction materials. The
construction aggregates of various sized and quantities available in the local area will be the
first priority of the project. According to the existing legal regime of the country, local
government are entitled to raise the revenue and taxes from the local resources utilized by the
project for the construction works. Similarly, the local governments have the rights to impose
tax on small business, which will boost up by the begnining of the project construction works.
Andhikhola Storage HEP (180 MW Environmental Impacts
EIA Report 5-35 NEA-ESSD
5.4.1.6 Potential Improvement of Public Facilities through CSP
The project has allocated 0.5% of total project cost as Community Support Program (CSP) and
suggested improvement of local services including health, education, sanitation and social
services. Project will support to improve water supply facilities, educational institutions, health
care institutions and local accessibility beforehand commencement of construction. Such
improvement is also required for the project to start and as some of these are necessary for its
construction crew as well. These programs are envisaged to help develop local infrastructures
and social services in the PAA. This in turn will help local people to improve their quality of life.
The impact will be direct in nature, high in magnitude, local in extent and long term in duration.
5.4.1.7 Hydropower Project Induced Development
As a result of the project implementation, induced economic development will take place in the
project area. The change in demand and supply situation, increase in economic activities, cash
flow, accessibility to services, infrastructure development will provide opportunity for emergence
of commercial banks, government and non-government offices, health and educational
facilities, tourism industry and other sectors. Similarly, development and expansion of market
centers, enterprises, agro-based industries will also flourish. The availability of better services
will improve the quality of life of local people, increase land value and infrastructures condition
in the area. The impact will be indirect in nature, moderate in magnitude, local in extent and
long term in duration.
5.4.1.8 Change in the Land Value
The value of the land that will be used for the construction of the project components and the
land nearby the project area will increase. This will also help to uplift the economic condition of
the local people. Hence, economic status of these communities will be increased due to project
implementation. The impact will be indirect in nature, moderate in magnitude, local in extent
and long term in duration.
5.4.1.9 Provision of Project Share to the Local People
The local people can have opportunity to invest in the project by allocating certain percent
(10%) of the total project investment as a share to the public and the people of the project
affected districts. The benefits from such investment are likely to improve the living standard of
the project area people.
5.4.1.10 Increase in Tourism Activity
The creation of a big reservoir will create a big opportunity to increase the tourism sector. Both
the internal as well as external tourists will be attracted to this place. In addition, the possibility
of boat operation as well as fish farming will help boost the tourism sector. Professional
peoples, students and researchers will be attracted to visit the AKSHEP to see how the project
is running in its operation phase. The impact is direct in nature, high in magnitude, local in
extent and long term in duration.
5.4.1.11 Increase in Living Standard
The employment opportunity will increase the income level of the local people. This will, in turn,
improve living standard of the local people. This increase is likely to enhance development and
promotion of other sectors particularly the social service sectors such as education, health,
sanitation and drinking water facilities in and around the surrounding project area.
5.4.1.12 Improved Health and Sanitation Conditions
The establishment of new health institutions and improvement/strengthening of existing health
institution will help local people to improve their health. Health and sanitation (WASH) training
Andhikhola Storage HEP (180 MW Environmental Impacts
EIA Report 5-36 NEA-ESSD
to local people during construction phase as well as occupational health related training to
workforce further increase the health and sanitation status of local people and area. The impact
is indirect in nature, moderate in magnitude, local in extent and long term in duration.
5.4.2 Operation Phase
5.4.2.1 Flood Regulation in the Wet Season
One of the major benefits of the storage project is the flood regulation. The proposed dam of
167 m height on the AndhikholaRiver has the capacity of 100% regulation of the flood water as
shown in the following figure.
Figure 5-4: Flood Regulation by AKSHEP on Andhikhola River
5.4.2.2 Water Available for Multiple use in the Dry Season
Hydropower Project: In case of storage type of hydropower project, water is stored and
regulated in controlled way for generation of electricity. Water release during dry season after
generation of electricity is additional availability of water in the river. The addition of the water,
downstream of powerhouse will help to increase the generation of the hydropower projects
being planned and constructed in the Kaligandaki River. Therefore, the execution of the
AKSHEP will benefit for existing and planned hydropower project, which are listed in Table 5-
18.

Source: DoED, 2019
Gandak Irrigation Project
Gandak irrigation project lies in the downstream of the proposed AKSHEP powerhouse.
Additional water available during dry season will be utilized by the irrigation project for irrigation
purpose. Therefore, the execution of the AKSHEP will also benefit for existing Gandak Irrigation
Project.
5.4.2.3 Reduction of sediment load
During operation phase, sediment will be retain behind the dam and no sediment load will
transport to downstream of dam. Reduction of sediment load will have positive impact on
downstream water user like Kaligandaki “A” hydropower, as the hydropower need not to bear
Andhikhola Storage HEP (180 MW Environmental Impacts
EIA Report 5-37 NEA-ESSD
sediment load from Andhikhola. As per preliminary estimation, the total sediment load is about
0.34 Tonnes/yr and consequences impacts of this sediment load need not to be bear by
hydropower. Similarly, reduction of sediment will also decrease siltation problem in downstream
irrigation project. Thus, the impact is direct in nature, moderate inmagnitude, and local in extent
and long term in duration.
5.4.2.4 Generation of Electricity Royalty
The project will generate royalty as per the provision made in Hydropower Development Policy,
2001. According to the Policy, as the proposed storage project is for internal consumption, the
AKSHEP will pay annual royalty to GoN at the rate of NRs. 200 per kilowatt for capacity and 2%
energy royalty per kWh for first 15 years of commencement of the project. After 15 years the
annual capacity royalty will be NRs. 1500 per kilowatt and energy royalty per kWh will be 10%.
As per the provisions in the Intergovernmental Fiscal Arrangement Act, 2074, Schedule-4, 50%
of the total royalty obtained from hydropower will be allocated to the Government of Nepal, 25%
to the concerned state and 25% to the concerned local level. This will certainly encourage the
local government bodies to invest in the environmental conservation as well as social-economic
development sectors. The impact will be direct in nature, moderate in magnitude, national in
extent and long term in duration.
5.4.2.5 Enhancement of Power Supply
Due to operation of AKSHEP, an additional installed capacity of 180 MW will be connected to
the national grid. The impact is indirect in nature, moderate in magnitude, regional in extent and
long term in duration.
5.4.2.6 Increase in Tourism Activity
The creation of a big reservoir will create a big opportunity to increase the tourism sector. The
project area is en route to Pokhara from Lumbini and vice versa, which are major tourism
destinations of Nepal. Both the domestic as well as international tourists will be attracted to this
place. In addition, the possibility of boat operation as well as fish farming will help boost the
tourism sector. The impact is direct in nature, high in magnitude, local in extent and long term in
duration.
5.4.2.7 Increase in Living Standard
The employment opportunity will increase the income level of the local people. This will, in turn,
improve living standard of the local people. This increase is likely to enhancedevelopment and
promotion of other sectors particularly the social service sectors such aseducation, health,
sanitation and drinking water facilities in and around the surrounding projectarea.
5.4.2.8 Reduction of Greenhouse Gases (GHGs) Emission
The proposed AKSHEP will generate annually 674.45 GWh of energy, which will reduce the
import of petroleum products from India. As the Indian energy market is dominated by fossil fuel
based energy production (mainly coal), the production of the clean hydropower from AKSHEP
will help avoid the import of such energy and help reduce the greenhouse gas emission. This is
one of the major benefits of the AKSHEP from the perspective of climate change mitigation and
reduction of GHG emission. The impact is indirect in nature, high in magnitude, national/global
in extent and long term in duration.

Andhikhola Storage HEP (180 MW) Alternative Analysis
EIA Report 6-1 NEA-ESSD
6 ALTERNATIVE ANALYSIS
6.1 Introduction Each project has unique characteristics depending upon its type, location and other factors
causing more alternatives that are possible. All possible alternatives are to investigate and
examine in order to find option that is more attractive. Primary objective of alternative analysis
is to select best option among different choices considering technical, environment and
economical aspect.
The technical feasibility of the project depends upon the water availability, topographical and
geological condition of the project area whereas the economic viability depends on the project
cost and benefit analysis and the environmental acceptability is the magnitude of the project
impact on the physical, biological, social and cultural environment of the project area.
Master Plan Study of the Gandaki River Basin financed by UNDP identified Andhikhola Storage
Hydroelectric Project in 1979. Different alternative layouts have been studied during various
study phase from 1997-2019. These alternative layout studied in different phase has been
discuss in following section.

A feasibility study Phase I of Andhi Khola Storage Hydroelectric Project was carried out in
1997/98 by NEA. The study has proposed the dam site D(I) at about 1.5 km upstream of
confluence of Andhi khola and Kaligandaki River. Another alternative dam axis D(II) has been
proposed at about 4.5 km upstream of confluence of Andhi khola and Kaligandaki River at
Chhare Village. The river bed level of Dam axis D(I) and D(II) is at 525masl and 560 masl
respectively. Two alternatives sites of power houses has been proposed with one at about 1.5
km downstream of the existing Kali Gandaki “A” HEP powerhouse and another alternative
Powerhouse has been located at about 12 km downstream of the existing Kali Gandaki “A”
HEP Powerhouse.
Hence, four alternatives of the project layout has been proposed are illustrated in Drawing
No.6.1. The comparison table of four options is as follows:

All the alternatives (options) were optimized for the 180 MW power generation from Andhikhola.
Irrespective of tunnel length, which is underground, the area occupied by all the project facilities
are almost same. All the alternatives are lies within the same geological area and administrative
boundaries. So, biological and social impacts of all the alternatives will not be significantly
different.
In all alternatives, Intake was located near at Illunga in private barren land. Dam axis of all the
alternatives was also located on private barren in Andhimuhan. Apart from 1997/98
recommendation, all other studies recommended power house in the same locality. Studies on
2013, and 2015 located powerhouse in private land whereas the 2018 study located it on forest
land.
In all the alternatives studied, access road for the dam axis will be the same. Accessibility to the
intake will be through construction of new road in private land of about equal length. New
access road to be constructed for the accessibility of powerhouse of all alternatives. The same
will provide accessibility to the powerhouse of alternatives 1, 2 and 3, and about 200m
extension on it will provide accessibility to powerhouse of 4. This shows that, there is not
significantly differences in social and environmental impacts in these alternatives studied.

While considering vegetation, vegetation information of the respective project components
presented in this EIA report gives exact analogy to the vegetation of respective project
component of different alternatives. In addition, all the biological information and predicted
project impacts on biological environment of all the alternatives studied will be same.
In social aspects, PAA of all the alternatives are Galyang municipality, Waling municipality,
Kaligandaki RM and Ramba RM. Reservoir of all the alternatives will inundate almost the same
area and locality. The same communities that are studied in this report are the impacted
communities of all the alternatives.
6.2.3 Project Layout according to the Feasibility Study Report of 2013
NEA carried out the feasibility study of Andhikhola Storage Hydroelectric Project in 2013. The
study had proposed the dam site D (III) at about 3.5 km upstream of confluence of Andhikhola
and Kaligandaki River.The river bed level of this location is 560 masl. Two alternatives sites of
power houses has been proposed with one at about 1.5 km downstream of the existing Kali
Gandaki “A” HEPpowerhouse and the other at about 12 km downstream of the existing Kali
Gandaki “A” HEPPowerhouse.
The tunnel length varies with the location of powerhouse. With the powerhouse P(I) at
Tokanchaur village, the layout has the tunnel length of about 1.60 km with inclined shaft length
of about 0.80 km and with the powerhouse P(II) at Balpuk village, the layout has the tunnel
length of about 5.20 km with inclined shaft length of about 2.0 km. The drawing No. 6.2
illustrates the project layout studided in Feasibility Study Report of 2013.Recommended option
layout plan of feasibility study report of 2013 is Dam D(III) with intake-2 along the Powerhouse
P(II) (Drawing No. 6.2)
6.2.4 Project Layout according to the Feasibility Study Report of 2014/2015
The Feasibilty Study (2014 and 2015) adopted four alternatives of project layouts. Two dam
axis has been proposed for the alternative study. One dam site D (I) is located at about 1.5 km
and another D(II) is located at 4.5 kmupstream of confluence of Andhi khola and Kaligandaki
River.The river bed level of D(I) and D(II) is 525masl and 560 masl respectively.Two possible
powerhouse locations were observed, both being on the left bank of the Kali Gandaki River.
One option is located at about 1.5 km downstream of powerhouse of the existing Kali Gandaki
“A” HEP with tailwater elevation of about 400 masl. And the another option is about 12.0 km
downstream of existing Kali Gandaki “A” HEP powerhouse with tail water elevation of 370 masl.
The Drawing No. 6.3 illustrates all the four alternatives.Recommended option layout plan of
feasibility study report of 2015 is Dam D(I) with intake (IA) along the Powerhouse P(II)
(Drawing No. 6.3)
6.2.5 Project Layout according to the Upgraded Feasibility Study Report of 2017-
2018/2019
In 2017, NEA technical team visited the project site and decided to change the previously
designed underground Powerhouse to Semi underground Powerhouse. Similarly, inclined
Pressure shaft has been changed to vertical Drop Shaft due to weak geological condition.
Furthermore, in November 2017, The JICA/NEWJEK Expert Team visited the Andhikhola
Storage HEP site and recommended the next alternative Dam Site D (IV) at 2.7 km upstream of
Andhikhola –Kaligandaki confluence.A new Intake (IB) site has been proposed which is about
600m upstream of previously proposed Intake(IA) site.Intake(IA) site located near Illunga
Andhikhola Storage HEP (180 MW) Alternative Analysis

village with wide valley which is found to be safe to provide the enough space for volume
required during sudden draw down of reservoir has been selected.
On the other side, Surge Shaft (II) has been selected as better option because it is safer and
easier to excavate. Therefore, the Surge shaft (II) has been chosen as better option.
The option Powerhouse P(IIA) is selected which is 12 km downstream of the existing Kali
Gandaki “A” HEP Powerhouse than Powehouse P(I),1.5 km downstream of powerhouse of the
existing Kali Gandaki “A” HEP due to the existence of big landslide. The Drawing No. 6.4
illustrates all the alternatives.Recommended option layout plan of feasibility study report of
2018 is Dam D(IV) with intake (IA) along the Powerhouse P(II) as shown in drawing No.
6.4.Here layout of 2018/19 is adopted.
6.2.6 No Forest Option
The proposed AKSHEP with an installed capacity of 180 MW has particularly impacts on
private unarable (Kharbari),cultivated and settlements land. No forest option was also studied,
but it is not practically possible due to the association with the forest patch. In order to avoid the
forest areas, project components are proposed either at the edge or low forest canopy cover.
The project and components is associated withgovernment forest and community forests. The
other project components will also be constructed in the cultivated area in order to avoid forest
clearance to the maximum extent possible.
In order to minimize and /or mitigate the loss of forest, the project proponent will provide
kerosene to the project working for cooking purpose. Besides, the replacement plantation in the
ratio 1:10 trees will be carried out in the project areas to mitigate the loss of trees with due
consideration with DFO offices and the Community Forest Users’ Groups of the concerned
districts. The implementation of the project will be done in accordance with the existing forest
acts, rules and regulations.
6.2.7 No Project Option
Nepal has been facing an acute shortage of peak load during the past few years. The present
installed capacity of the Integrated Nepal Power System (INPS) is only about 1050 MW as of
July 2018/2019 and the peak demand is nearly 1500 MW. The construction of the run-of-river
type of projects will generate surplus power in the wet season, while there is a deficit during the
dry season. Therefore, storage projects like AKSHEP is essential in order to balance INPS
throughout the all seasons.
Andhi Khola Storage HEP (180 MW) Mitigation and Enhancement Measures
EIA Report 7-1 NEA-ESSD
7 MITIGATION AND ENHANCEMENT MEASURES
The mitigation and enhancement measures outlined in this chapter have been proposed to
minimized potential adverse impacts and enhance the beneficial impacts identified during the
study. Adverse and beneficial impacts those that are not identified or predetermined during the
study, if later discovered during the construction phases will be explicitly mitigated or enhanced
by the project proponent.
The general discussion is organized into three categories of physical, biological, and socio-
economic and cultural aspects, and has been split into construction and operation phases in an
equivalent manner as for Chapter 5 - Environmental Impacts. The mitigation measures to be
carried out have been listed below. The project proponent will implement all the proposed
mitigation measures and enhancement measures, monitoring plans described in the respective
chapters as his prime responsibility. In addition, the project will take responsibility of
compensating as per the prevailing law for any losses or damage caused to livelihoods and
property during construction and operation phases.
7.1 Physical Environment To minimize the adverse impacts and maximize the environmental benefit on the physical
environment aspect of the AKSHEP following mitigation measure have been proposed.
Minimization of land taken and soil disturbances wherever feasible will be the primary mitigation
measures of the project.
7.1.1 Construction Phase
7.1.1.1 Topography and Land Use
The project will acquire approximately 913 ha permanently and 52.82 ha temporarily. The
impact on permanently acquired land is unavoidable. Still, there are opportunities in re-
establishing the existing land for better quality. The area used by the project like labor camp,
spoil and muck disposal area, quarry sites etc. will be temporarily acquired and will be restore to
better condition with proper landscaping before return to the land owner.
Wherever possible, the project will utilize lower value production land for project facilities in
preference to higher value land. The permanently acquired land will be compensated as per
government rules.
7.1.1.2 Soil Erosion and Land Instability
Soil erosion and land instabilities are mainly due to construction of the access roads, quarry site
and barrow pits. To minimize the probable adverse impacts following mitigation prescription
have been proposed:
Access road
• Balancing of cut and fills in the road construction alignments – cut sites and filling sites
shall be delineated prior to excavation.
• Construction of retaining walls and gabions to protect soil mass
• A drainage plan for the access roads shall be developed to minimize the effect of drainage
disruption and associated erosion and sedimentation.
• Minimization of clearing and ground disturbance
• Topsoil saving- Fertile topsoil will be removed and stockpiled at identified suitable site for
reuse and rehabilitation.
• All cut and fill area shall be rehabilitated progressively using suitable bioengineering
measures.

Quarry and Barrow pit
To minimized soil erosion during excavation works following prescription are recommended;
• Avoid the big and deep borrow pit at one location.
• The quarry operation shall not be carried below the flowing water level of the river
• Surface strip mining will be enforced for the extraction of aggregate
• The water discharge from aggregate washing plant will be collected in settling tank/ponds
at suitable location for sedimentation and treatment.
Underground Work
• Controlled use of explosive to limit the disturbance to ground condition.
• Use of rock breaker instead of explosive are effective for the excavation of weathered rock
and will be enforced
Spoil Disposal Site

• Spoil will not be deposited across the drainage line.
• Toe protection wall for all spoil disposal site.
• Benched outward slopes on the spoil deposits to avoid slope failure
• Spoil disposal area will be located above the high flood level
7.1.1.3 Changes in Air Quality
To minimize the impacts on local air quality during construction of project components following
measures are recommended:
• Regular sprinkling of water in the earthen/gravel of road corridor at least three times in a
day in dry season;
• Compact and water sprinkling regularly in the spoil disposal site
• Speed limits for the vehicles plying in the dusty construction roads
• Use of construction vehicles/equipment/compressors/diesel generating sets comply with
government mass emissions standard
• The project will discourage the use biomass as fuel within the camps for heating and
cooking purpose. The project will ensure that an alternate commercial fuel for the heating
and cooking within the project camps.
• Stabilization and covering of the loose stockpiles by using appropriate measures.
7.1.1.4 Noise and Vibrations
Following measures have been recommended for the control of noise and vibration during
implementation.
• Speed restriction to the construction vehicles in areas close to the settlement and
structures.
• Restriction on unnecessary use of Horns
• Regular maintenance of all the equipment as per manufactures specification to reduce the
engine noises
• Aggregate crushing and blasting work in day time
• Strict to control blasting limited to extent that is required at its minimum level to minimize
noise levels and vibrations.
• Notification to the communities prior to noisy activities (particularly surface blasting)
• Compensation to the damage of structure, if found related to the vibration and
overpressure.

EIA Report 7-3 NEA-ESSD
7.1.1.5 Changes in Water Quality
To minimize the impacts on the water quality of the nearby water bodies and other surface and
sub-surface receiving water bodies following mitigation measures are recommended.
• Provision of a good sanitary facilities with adequate toilet, washing tap, drinking water
facilities and sanitation facilities in the construction camp
• Prohibition of the discharge of the sanitary liquids and toxic liquids such as spent oils,
burnt mobile, grease, lubricants, grouting chemicals etc. in land and water bodies from the
construction sites.
• Establishment of separate area for the collection and storage of hazard and toxic material
waste including batteries, oil filters, Mobil, burnt oil etc.
• Provision of solid waste management system at Camps. Establishment of separate
storage area for the wastes of packing materials such as plastic bag, jute bags, cardboard,
paper etc. for later reuse or sale
• Prohibition on open urination and defecation in waterways, around camps and
construction sites,
• Establishment of primary water treatment facilities for effluent discharges of the tunnel;
aggregate washing plant and cement batch plant on each work site and release the
discharge only after primary treatment. This can be done with the establishment of
sedimentation ponds/tank so that waste water is allow to pass through sediment tanks
before release in land or water bodies
• Prohibition of quarrying of aggregates and sand from the river’s wet channel
• Provision of training to the labor force in using storage areas with regard to safe handling
to toxic and non-toxic water material.
7.1.1.6 Changes in Soil Quality
Various construction activities generate different types of wastes, which has to be disposed on
land. This will have direct impact on soil quality in the construction period. The mitigation
measures prescribe for water quality is adequate for avoidance and minimization of land
pollution.
7.1.1.7 Spoil and Muck Management
Spoil generated from construction of tunnel can be managed in construction of dam and nearby
land development. Following are some recommended works for proper management of spoil
and muck.
• First priority will be given for reduce and reuse of spoil.
• Segregation of spoil as stone, aggregate and soil. Use stone for structure, aggregate for
construction and soil for backfilling
• Use of spoil in backfilling and leveling of road.
• Use spoil for backfilling and land development with proper compaction, grading
• Use of Muck in construction of dam and other embankment
• Muck generated also can be used in upgrading the internal and local earthen road
• Construction of toe wall or retaining wall at dumping site.
• Construction of side drain and surface drainage system at dumping site.
7.1.1.8 Labor Camp Management
External labor force can introduce social conflict, deforestation, pollution of surface and ground
waters from unsanitary waste disposal practices. The following mitigation measures will be
taken during construction period of project.
• Camp will not be located near settlements
Andhi Khola Storage HEP (180 MW) Mitigation and Enhancement Measures
EIA Report 7-4 NEA-ESSD
• Camp will be operate within a self-sufficient infrastructure like water supply, toilet.
• Workers will be prohibited from poaching wildlife and cutting tree
• Cooking fuel, Water and sanitation facilities will be provided within the camp
• Solid waste will be managed according to the following preference hirerachy: reduce, and
reuse,
• After completion of work, the site will be rehabilitated to improved condition
7.1.1.9 Stockpiling of Construction materials
The mitigation measures that will be followed for the impacts associated with stockpiling of
construction materials are as below;
• Stockpiling sites will be properly fenced. Side drain will be constructed mixing of chemicals
and explosive to the water bodies and soil will be prohibited.
• Leased land used for stockpiling will be restored into original shape to the extent possible.
• The project will make necessary arrangement for the proper storage and handling of
construction material to avoid environmental nuisance.
• As far as possible the stockpiling of construction material will be carried out in treeless area
or barrenland
• The cost required for the mitigation of impact generated from construction activities has
been incorporated in the civil cost of the project
7.1.1.10 Changes in River Morphology due to Quarry sites
All the activities within the riverbed will be planned properly during the construction stage. After
quarrying of construction materials, land will be rehabilitate to the natural condition.
• Quarrying operation in the flood plain will be stripping operation rather than forming a big
borrow pit at one location
• The quarry operation will not be carried below the flowing water level of river
• Excavation of aggregate from the river wet channel will be prohibited.
• Maximum digging of quarry sites will be maintained up to 3 m considering vulnerability of
site.
7.1.1.11 Handling of Explosive
The handling, storage and operation of bunker house, explosive and detonator will be done as
per GoN rules under direct supervision of Nepal Army.
Proper handling of explosives includes the following requirements:
• The explosive procurement, transportation, storage and use is strictly controlled by the
provisions of the Explosive Act in Nepal
• Explosives will be kept at bunker under the direct supervision and security of Nepal Army;
• The explosive will be procure, transport, storage and use under the supervision and security
of Nepal Army;
• Access to explosives will be tightly controlled; and
• Explosives will be handled in accordance with the manufactures instructions and
specifications and other relevant standards and regulations practiced by Nepal Army
7.1.2 Operation Phase
7.1.2.1 Land stability and erosion control
Landslides and soil erosion can be triggered by many causes like rainfall, slope digging,
excessive weight above slope, and earthquake force. Settlement like Gyalang, Illunga, Chharak,
Devisthan are located at uphill side of Andhikhola. Soil erosion and landslide brings disaster to
the settlement particularly when settlement are located at uphill side. Hence, it is required to
Andhi Khola Storage HEP (180 MW) Mitigation and Enhancement Measures
EIA Report 7-5 NEA-ESSD
take slope stabilization measure during operation phase of project around the reservoir area.
Slopes strengthen and protection is necessary at downhill side of these settlement and other
potential weak zone. Following measures are recommended for slope stabilization and detail
design and assessment is to be incorporated in detail design of project.
• Reinforcement measures with metal nails or anchors in order to increase the shear strength
of rock.
• Shotcrete onto the surface with the concrete. This stabilization method also used to improve
stability of rock slope.
• Surface erosion control measures with different techniques like, use of geogrids and
geomats, steel wire mesh, breast wall, stone pitching and bioengineering works.
7.1.2.2 Impact related to Upstream water user
Andhikhola Hydroelectric project (9.4MW): The implementation of proposed project
inundated the intake structure of existing hydropower of 9.4 MW. The average annual energy
generated by this hydropower is about 70.73 GWh. With the implementation of proposed
storage project, there will be loss of capital invested in this hydropower and revenue earn from
energy for the existing hydroelectric project.
As per the power purchase agreement (PPA) between NEA and BPC, if NEA constructs
Andhikhola Storage HEP, BPC will not get any kind of compensation for the inundation of
headwork structure of existing Andhikhola HEP and other loss related to energy and revenue.
However, if BPC wise to continue to operate existing hydropower, it can modify or relocate the
intake site with its own cost without any additional cost to the NEA. Thus, there exist two case
scenario for BPC; first, continue to operate existing HEP with modification of intake and second,
terminate to operate existing HEP.For this Seneriao Management plan is prepared in section
9.6.2
Irrigation system operated by AKWUA: The intake of existing hydropower not only serves
water for the hydropower but also for irrigation system in some area (about 500 ha) of Palpa
and Syanga district. Thus, there will be loss in the productivity of irrigated area with the
implementation of proposed storage project.
It is therefore, valuable to preserve the benefit associate with existing hydroelectric project and
irrigation system. To mitigate the impact on the existing hydroelectric project, and irrigation
system, renovation or relocation of intake structure and headwork structures along with tunnel is
recommended. The detail works need to be carried out during detail design phase of the
proposed project.
7.1.2.3 Impact related to Physical Infrastructures
With the development of project, infrastructure like RCC Motorable bridges, trail bridges,
existing road, office buildings, religious structures etc. will be affected within reservoir area.
Project proponent will be responsible for compensation of these structures and construction of
necessary structure for movability of local people. Therefore, detail works need to be carried
out during detail design phase of project in order to provide accessibility and movability of local
people for the construction of road, and trail bridges or motorable bridges or any other means of
transportation.
7.1.2.4 Protection of reservoir rim failure or draw down
The rise and fall of the reservoir water level take place during operation period of hydropower.
This alternate varying condition in soil mass brings structural weakness leading to the failure of
slopes around the reservoir rim. Slope stabilization works need to be carried out around the
Andhi Khola Storage HEP (180 MW) Mitigation and Enhancement Measures
EIA Report 7-6 NEA-ESSD
reservoir inundated area. Soil nailing, shotcreting, grouting, dry or wet stone pitching methods
can be used for slope protection. For this purpose, detail geological investigation around the
reservoir area need to be carried out and protection work need to be done accordingly.
7.1.3 Recommendation for future Study
1. Alternative Analysis considering upstream water user
Existing hydropower and irrigation facilities have provided significant advantage to the local
level. To secure benefit and capital associate with existing project, an alternative analysis is
recommended considering the existing hydropower and irrigation system. Hence, it is crucial to
study the project as multipurpose project. The detail work for this need to be incorporated during
detail design phase of the proposed project.
2. Landslide Hazard Assessment Work
During field study, major and minor landslides within the watershed and along the both sides of
Andhikhola were observed. There are settlements like Galyang, Illunga, Sera, Charrak,
Devisthan, Bayatari at uphill side on either side of Andhikhola. It is therefore, recommended for
the landslide hazard assessments of catchment area of Andhikhola so that possible risk
associated with land stability and erosion can be evaluate and mitigate in time. The detail work
for this should be done during detail design phase of the proposed project.
7.1.4 Summary of Mitigation Cost for Physical Environment
Table 7-1: Preliminary Cost Break Down of Physical Environment
S.N. Description Cost (NRs)
1 Hazard assessment (for initial 5 years of operation) 1,00,00,000
2 Protection of reservoir rim erosion (for initial 5 years of operation) 15,00,00,000
3 Protection of Highway near Galyang Bazar 10,00,00,000
Total 260,000,000
7.2 Biological Environment The mitigation measures prescribed for the impacts on biological environment during the project
construction and operation phases are as follows:
7.2.1 Construction Phase
7.2.1.1 Minimizing the Forest Clearance
Loss of forest for the proposed project is unavoidable. In the reservoir area of the project, the
potential forest clearance area is up to the free board area of reservoir, that is, 710 masl. So, in
order to minimize the forest clearance, felling of trees above the full supply level of the reservoir
will be minimized to the extent possible. In the access road area, not all the trees within the
RoW of the roads will be felled. Trees within the formation width (Carriageway, shoulder and
drain) will be felled.
7.2.1.2 Compensatory Plantation and Forest Land Replacement
Loss of forest is unavoidable in this project with project development options. Two mitigation
options could be envisaged to mitigate the impacts in the forest: Compensatory measure and
Offset measure. To mitigate potential impacts in terms of biodiversity and forest, implementation
of offset measures will be the first option. In line with the “Working Procedures with Standards
for the Use of National Forest Land for National Priority Project-2076”, the project will
afforestrate 10 saplings for every single tree loss in an area not exceeding 1600 trees per
hectare, and will look after for five years. In total 81,920 seedlings will be planted as
compensatory plantation. The proponent will request to DFO, and FUGs to locate the land for
Andhi Khola Storage HEP (180 MW) Mitigation and Enhancement Measures
EIA Report 7-7 NEA-ESSD
plantation. Plantation designs for each specific sites identified will be developed after
consultation and interaction with the concerned stakeholders. As an option, the proponent will
deposit the required amount as per the forest norms to the division forest office required for
afforestation and 5-year caretaking. The proponent will also make necessary arrangement for
training on forest development to users.
Similarly, as per the same Working procedure, forestland replacement will be done. As this
project will permanently acquire 17.765 ha of forest, the project shall purchase same area of
land, in other place, and hand over to the MoFE. For purchasing of 17.765 ha of land, NRs.
28,399,573/- (@1,598,625/ha) is estimated as per appendix I of the same working procedure.
Before handing over, the afforestation will be done in these land (at the standard ratio of 1600
seedlings per ha). Therefore, plantation of 28,424 number of seedlings will be done for 17.765
ha of permanently acquired forest. In total 110,344 number of seedlings will be planted.
7.2.1.3 Harvesting Cost
In line with the “Working Procedures with Standards for the Use of National Forest Land for
National Priority Project-2076”, the project will make all financial arrangement for harvesting,
logging and transportation of logs to the DFO. The compensation cost for the harvesting,
logging and transportation of forest is part of project construction work and will be included in
construction cost hence it is not estimated separately in this EIA Report.
7.2.1.4 Compensation to Private Tree loss
As far as possible, project will minimize the tree loss from the private land. In case of reservoir
inundation area and camp area, tree loss in unavoidable. Detail inventory of private trees (fruit,
fodder and timber) to be felled will be prepared with the help of DFO, DHR and District
Agriculture office. The project will paid cash compensation to all private tree loss.
7.2.1.5 Supply of Fuel to Workers
To the extent possible, construction workers will be prevented from the use of fuel wood for
cooking their food items. The project proponent will provide either kerosene/LPG or any
alternative fuel to the extent possible to project workers staying at temporary/permanent labor
camps to minimize forest loss in order to meet their fuel wood demand. Similarly, provision of
fire-fighting equipment at vulnerable areas and training of workers in the use of this equipment
will be carried-out.
7.2.1.6 Controlling NTFPs Collection
Construction labor will be strictly prohibited to enter into the nearby forest and the private land
for the collection and type of the NTFPs. Project and proponent in coordination with the
respective CFUGs and local people will control the NTFPs collection by labour. Similarly, the
project in coordination with the DFO will implement awareness raising program to the local
people.
7.2.1.7 Habitat Loss and fragmentation
The impact of vegetation clearance on habitat loss/change is a permanent phenomenon.
However, the compensatory plantation of trees and awareness for forest management and
wildlife conservation is considered to help for minimizing the impact to some extent. Selection of
the tree species for the compensatory plantation will be done to develop a healthy forest
ecosystem comparable to lost one. The clearing of trees will be done manually causing less
impact on adjoining vegetation.
Andhi Khola Storage HEP (180 MW) Mitigation and Enhancement Measures
EIA Report 7-8 NEA-ESSD
7.2.1.8 Restriction on Hunting and Poaching
The project workers will strictly be prevented from hunting and poaching, and any other kind of
illegal activities related to hunting and poaching. The construction work within forest area will be
coordinated through DFO and FUGs. Informative and warning sign will be placed at relevant
construction sites. The contractor who is liable to control his labor in this regard will be
instructed strictly for application of specification regarding hunting and poaching control.
7.2.1.9 Minimizing impacts of Construction Disturbances
Construction disturbances of the project will be minimized by the following ways;
a) Re-route of material delivering vehicles away from the settlement and forest if possible.
b) Place noisy site equipment away from forest/settlement area.
c) Combine noisy operation to occur in the same time; the total noise level produces will
not significantly greater than the level produced if they are operated separately.
d) Do not work in nighttime.
7.2.1.10 Impacts on Protected Species of Flora and Fauna
The proponent and contractor will strictly control their labour force to enter into forest and fishing
activities. The AKSHEP in coordination with CFUGs will conduct awareness campaign to the
construction workers and local people.
7.2.1.11 Fire hazards
Dry biomass of the forest and vegetation after the site clearance will be properly managed. The
contractor shall aware the labour force on potential sources of fire hazard and will train on use
of fire fighting. Contractor will manage fire fighters to every labour camp.
7.2.2 Operation Phase
7.2.2.1 Compensatory Plantation and Forest Land Replacement
As per the “Working Procedures with Standards for the Use of National Forest Land for National
Priority Project-2076”, the plantation site shall be managed by the proponent for five years or
required cost for such management must be paid to DFO.
7.2.2.2 Habitat Loss and fragmentation
Poundage by reservoir will have significant habitat changes in the aquatic water body. Not all
the impacts of the project could be mitigated. To minimize the adverse impacts in the dewatered
zones, minimum flow in the dewatered zones of the Andhikhola River will be maintained.
Existing fish hatchery of Kaligandaki HEP will be upgraded.
The issues of habitat fragmentation of wild fauna is hard to address and the impact is
unavoidable in the propose project. Therefore, the project in coordination with the DFO office
will help to maintain the healthy wild environment at downstream of the reservoir to allow the
wildlife movement if any. During operation phase, no mitigation measures will be adopted
regarding habitat loss/ change of wild animals and birds.
7.2.2.3 Downstream Flow Release
Flow is a key feature in determining the complexity of aquatic habitats within the river’s riffle, run
and pools environment. In the above three environments of the river, the water flow velocity has
a special relationship with the substrate that influences aquatic macro and micro invertebrates
and algae growth, which are very important to riverine fish and river using predators. In Nepal
there is limited information of minimum water requirements for survival of fish in nursery pools
during dry season. Knowledge on the physical factors such as flow characteristics, temperature,
water quality, which influences the migration, and spawning of these fish species, is also limited.
Andhi Khola Storage HEP (180 MW) Mitigation and Enhancement Measures
EIA Report 7-9 NEA-ESSD
The dewater zone of the project is about two km. So, the project will release not less than 10%
of the minimum monthly average discharge (0.31 cumec) as per the Hydropower Development
Policy, 2001. The downstream release from the dam is important factor as it is related with
downstream water uses and survival of downstream aquatic life and fish migration.
The dewater streatch of the dam is about 2km as there is Kaligandaki dam downstream. In that
2 km streatch there is no any water users except Kaligandaki HEP. So, 10% of the minimum
monthly average discharge from the dam will not have any impact on downstream users except
Kaligandaki.
Regarding aquatic life, fish ladder will not be effective measures to allow fish migration in such
167 m high dam. So, provision of fish hatchery has been proposed. Regarding downstream
flow, the dewater streatched is short. Back water from the Kaligandaki dam regularly inundate
almost the whole streatch between two dams. So, not less than 10% of the minimum monthly
average discharge from dam will not have significant impact on the aquatic life.
7.2.2.4 Fish Hatchery
The construction of the dam will convert the lotic system to lentic system in the upstream region
(reservoir area), which will affect the aquatic diversity. Therefore, the changed environment may
not be suitable for the native water current loving fish like snow trout. However, some open
water stocking program for snow trout will be carried-out.
Upgradation of fish hatchery of Kaligandaki HEP is proposed. In order to improve the livelihood
of the project-affected people, fish fingerlings will be produced, released upstream, and
downstream of the dam of Andhikhola as well. The locals will be encouraged to establish
community-level fish farming. The fish-breeding center will focus not only on improved varieties
of fish for commercial farming but also in the conservation of the native fish species. For the
upgradation of fish hatchery, NRs 10,000,000 will be allocated.
7.2.3 Enhancement Measures
Enhanced measures proposed in this section aims to enhance the beneficial impacts of the
project and either prevent or minimize the negative impacts of the project. As an enhancement
measure, awareness raising and conservation of wildlife and management of forest.
7.2.3.1 Training on Forest Management

7.3.1 Construction Phase
7.3.1.1 Acquisition Land and Structure
i. Compensation for Permanently Acquired Land
Land for reservoir area and over which structures will be constructed will be permanently
acquired whereas land required only for construction purpose will be temporarily leased for the
required period. Project will provide appropriate compensation to all of the PAFs/SPAFs as the
rate determined by Compensation Determination Committee (CDC). During the public
consultation, local people demanded cash compensation for the affected land. According to the
GoN laws and regulations, it is mandatory to provide cash compensation for the acquired land
and property. Compensations paid and settled immediately after acquisition are administratively
much simpler and economically.
The project will acquired 780 ha of private land. Out of total, 734.566 hector is permanent land
(for reservoir, camp areas of dam and powerhouse and access road) and 45.21 hector is
temporary land (for labor camp, muck disposal area, bunker site, and stock piling area). Land

7.3.1.19 Resettlement and Rehabilitation Plan (RRP)
An overview of the GoN policies on resettlement indicates land-for-land compensation, with the
additional monetary compensation for the loss of assets and livelihoods, as the most preferred
policy. However, review of the i) availability of land under government ownership both onsite
and offsite the AKSHEP, and ii) availability of sizable land from willing sellers both onsite and
Andhi Khola Storage HEP (180 MW) Mitigation and Enhancement Measures
EIA Report 7-18 NEA-ESSD
offsite of AKSHEP, reveals insufficient land is available for the land based resettlement of
affected HHs. From the field observation, it was observed that the SPAFs don’t want to resettle
voluntarily.
The reasons behind unwillingness for resettlement are adaptation problem in new society and
traditional and cultural attachment to the existing place. During the HH survey, the SPAFs were
asked about their preferences for: i) relocation to new resettlement sites or ii) compensation of
the lost assets at market price. Majority of HHs would prefer housing land with the
compensation in new resettlement sites.
a. Relocation of Houses
The physically displaced HHs due to project activities (reservoir, dam, powerhouse, access road
area) will be relocated in groups in an integrated settlement (IS) as these HHs do not have any
other residential houses. These HHs are categorized as SPAFs. The relocated HHs will be
supported by a range of rehabilitation packages including Livelihood Restoration Training (LRT).
The IS will be developed with all other infrastructure support facilities such as road, water supply,
drainage management, electricity, communication, educational institutions, health care facilities,
community hall, etc.
The relocated sites will be finalized before the construction work starts with close consultation
with affected HHs and representative of local bodies. As these new sites for relocation of the
physically displaced people are not specifically identified at the site at this stage of the study, the
impacts caused by these sites to the specific households is yet to be identified.
b. Applicable Policy and Legislation

7.3.2 Operation Phase
7.3.2.1 Decrease in agriculture production due to structural location of the project
components
The top soil preserved and stored at the appropriate place of construction camp area will be
spread uniformly to the restored temporarily acquired agricultural land before returning. During
operation of the project, the maintenance works will be carried out in such a way that
disturbance to nearby agricultural land is minimum.
The members of the PAFs, whose agricultural land will be acquired by the project, will be
provided with agriculture enhancement training on poultry and livestock raising, fresh vegetable
farming, fish farming as to compensate the loss of agriculture production. Such training program
will be given to affected local farmer for one time only. The higher priority will be given to the
women of disadvantage groups. Further new skill training as environmental enhancement
program will be launched so that PAFs and SPAFs can switch their occupation.
7.3.2.2 Sudden Release of Water Downstream of Powerhouse and Dam
Solution to the impact is classified into two situations – planned release and sudden release of
water to natural Kaligandaki River course. For planned release, schedule of release is exactly
known before but since sudden release will take place due to some technical difficulties, it may
occur at any time. AKSHEP will take following corrective action to address the possible impact:
Planned Release
The project will notify the concerned communities about the plan of release through written
notices, mouth to mouth information, awareness program and all other possible means
identified later. Besides, the project will install alarm-warning system (siren) at appropriate
location so that alarm sound is circulated to all concerned. Warning signal (siren) will be made
at least three times (before 1 hour, 30 minutes and 15 minutes) before water is released from
the dam by the project staff. Local people will be given awareness training to safeguard their
livestock from the flood plain area after the siren is blown.
Sudden Release
AKSHEP will install alarm system so that in case of sudden shut down of powerhouse or tunnel,
the system will automatically ring loudly for at least 5 minutes. The released water will take
some time to travel downwards during which people nearby riverbank will have sufficient time to
move to safety.
7.3.2.3 Possible impact on people's behavior and local economy due to decrease
economic activities
Upon the completion of the project, most of the skilled labor will lose job and there will be
slowdown in economic activity which is expected to bring in frustration to local people who have
benefiting. The project will take following preventive measures to minimize the impact and for
smooth transition from construction phase to operation phase;
❖ The project will try to appoint maximum number of local people as far as possible during
the operation period.
❖ The project will run counseling programs to tell the workers about the availability of
works in similar projects running elsewhere in Nepal demanding the skills they acquired
from the Project.
Andhi Khola Storage HEP (180 MW) Mitigation and Enhancement Measures
EIA Report 7-20 NEA-ESSD
❖ The local farmers, business people and traders will be made aware of the income
generating activities that could be operated by the availability of the electricity in their
area.
❖ In addition, skill training program as an Environmental Enhancement Program will be
carried out so that people can switch their occupation easily based on their skill and local
availability of resources.
7.3.2.4 Possible Impact on Gender and Children
Since no significant impact on women, children, and other vulnerable group is expected during
the operational phase, no mitigation measure is required.
7.3.2.5 Occupational Health Hazards
To safeguard the potential occupational health and safety risks following preventive and
corrective have been suggested during operation period.
❖ The contractor of AKSHEP has a designated administrative control unit within its
organization structure to formulate health and safety polices, health and safety training
to employee, health and safety inspection system, health and safety plans etc are
required for the avoidance of the health and safety related hazards in the working
environment.
❖ The contractor of AKSHEP has provides OHS training to all construction workers
relating to perceived OHS risk/hazard at the work sites,basic site rules the at work sites
for self protection against the perceived hazards,use of different personal protective
equipment to safeguard from different hazard types,use of first aid and emergency
procedures for safety and evacuation etc.
❖ The contractor of AKSHEP has established and maintained appropriate equipped first
aid station to all the construction site which shall have adequate supply of first aid
medicines, adequate washing facility equiped with gloves, gowns and masks for
protection against direct contract with blood and other body fluids and health stabilization
facility.
❖ The contractor of AKSHEP has established and maintance fire fighting equipment in all
construction and camp site
❖ Workers health will be checked periodically on the status of their health.
❖ Personal Protective Equipment (PPE) such as safety helmet and glass, safety boot, ear
plugs, good electric light system, good earthling devices, fire-fighting accessories,
caution signals, safety belt and other safety equipment as required at particular site and
working area will be provided. Personal protective equipment for eye and face
protection, head protection, hearing protection, foot protection, hand protection,
respiratory protection, body and leg protection etc.
❖ Provision of field hospital and ambulance.
❖ Supervision and monitoring of the occupational safeguard practice at work sites
❖ The contractor of AKSHEP has prepare a plan to handle emergency situation in case of
accidence or major construction risk.
7.3.2.6 Impact on Water use Right and Conflict
Nearby settlements of Andhikhola are dependent on the river for irrigation, fisharies and other
domestic uses of water. AKWUA is one of the major water users dependent on the river. So, the
future development work on andhokhola need to ensure the continuous water supply for that
Andhi Khola Storage HEP (180 MW) Mitigation and Enhancement Measures
EIA Report 7-21 NEA-ESSD
irrigation scheme. Therefore, the project will continuously supply water to the AKWUA. In
addition, drinking water supply in the region impacted by the project will be restored.
7.3.2.7 Impact on Cheap Electricity provided by BPC
BPC was providing cheaper electricity tarrif comperation to the NEA at present. As per the
power purchase agreement (PPA) between NEA and BPC, if NEA constructs Andhikhola
Storage HEP, BPC will not get any kind of compensation for the inundation of headwork
structure of existing Andhikhola HEP and other loss related to energy and revenue. However, if
BPC wise to continue to operate existing hydropower, it can modify or relocate the intake site
with its own cost without any additional cost to the NEA. Thus, there exist two case scenario for
BPC; first, continue to operate existing HEP with modification of intake in this case existing
system is continuous in operation .Therefore there is no any question to revise electricity tariff
provided by BPC .In second case if terminate to operate existing HEP,electricity tarrief will be
revised as per the power purchase agreement (PPA) between NEA and AKSHEP .
7.3.3 Enhancement Measures

Andhikhola Storage HEP (180MW) Review of Policies and Legal Provision
EIA Report 8-1 NEA-ESSD
8 REVIEW OF POLICIES AND LEGAL PROVISION
8.1 Introduction Nepal integrated environmental aspects in all its development activities and projects only from
early 1980s. Environment conservation was included in the policies since the Fifth Plan (1975-
1980). The second milestone was taken during the Sixth Plan. The Sixth Plan under the
environment and land use policy emphasized the integration of environmental aspects into the
construction of large-scale development projects. Then finally, in the Seventh Plan it was stated
that developmental programs would be implemented only after an approved EIA/ IEE report.
The Eighth, Ninth and Tenth Five Year Plans have further emphasized the making of more
effective EIA systems. The formulation of sectoral Guidelines, promotion of participatory
EIA/IEE system and inclusion of mitigation cost into the total project cost were some of the
activities included in these three five year plans.
The prevailing Acts, Policies, Regulations and Guidelines, which are required for the
construction and operation of hydropower projects in Nepal, have been reviewed as per the
following while preparing the present EIA report. The proponent will abide by any other laws
besides those already mentioned in the documents that are attracted due to different activities
that will be undertaken during project implementation.
8.2 The Constitution of Nepal In the Article 30 of Part 3 of the Constitution of Nepal states about the Right to Clean
Environment: According to this article all citizens shall have the right to live in clean
environment, and in case if there is injury caused from environmental pollution or degradation,
the victim have the right to obtain compensation. In the same way, Article 51(g) explains
Policies relating to Protection, Promotion and use of Natural resources under the Policies of the
State as follows;
• to protect, promote, and make environmental friendly and sustainable use of, natural
resources available in the country, in consonance with national interest and adopting the
concept of intergenerational equity, and make equitable distribution of fruits, according
priority and preferential right to the local communities,
• to make multi-purpose development of water resources, while according priority to
domestic investment based on public participation,
• to ensure reliable supply of energy in an affordable and easy manner, and make proper use

Andhikhola Storage HEP (180MW) Review of Policies and Legal Provision
EIA Report 8-2 NEA-ESSD
8.3 Plan and Policy
8.4 Nepal Environmental Policy and Action Plan, 2050 and 2055 Nepal Environmental Policy and Action Plan (NEPAP) were endorsed to further institutionalize
environment protection in the development processes. The NEPAP recognize that a growing
number of people are exposed to pollute from industrial enterprises. The NEPAP identifies the
following factors as contributing to this process:
• Industrial plan inappropriately cited close to population centers
• Insufficient emphasis on fuel efficiency
• Little, if any pollution abatement equipment used for reducing emission, and
• A total lack of industry pollution standards
Hence, NEPAP emphasizes the need for mitigating adverse environmental impacts to address
urban and industrial development, air and water pollution and infrastructure development.

8.5.18 Landuse Act, 2076
The Land Use Act, 2019 has come into force in Nepal. As per the act, land has been classified
into 10 categories: agricultural; residential; commercial; industrial; mining and mineral; forest;
river, stream, pond and wetland; public use; cultural and archaeological; and others. The land
classification is based on the composition and use of the land. The classification has not clearly
pinpointed guthi land, which is religious land in the name of temples or shrines, from the
revenue of which the religious ceremonies or festivals associated with the temples or shrines
are celebrated and the repairs and maintenance of the temples or shrines are carried out.
The act has been introduced based on the condition of land, population growth, requirements of
land for various purposes like food and habitation and the need for economic development and
infrastructure building, among others. The main aim of the act is to ensure that land is properly
used and managed and that land set aside for one purpose is not used for other.
The act has assigned the responsibility for implementing the act to not only the federal
government but also to the provincial and local governments. As per the act, three tiers of the
government should constitute councils to bring provisions of the act into implementation. The
federal government should draft maps of all the local levels and ensure that all the local
governments are abiding by provisions of the act. The local governments, on their part, should
ensure that the people are adhering to provisions of the act. For this, they will have to form
implementation committees under the leadership of the heads of the local governments. So the
local levels have a major role to play in ensuring implementation of the act.
The provincial and local governments are also required to formulate their own land use laws
based on the act. The federal government can review the land use plan every seven years,
whereas the provincial governments can do so every five years. The local governments can,
however, review the land use plan as and when required. Such a review can be made on the
basis of changing patterns of demography, urbanisation, specific needs for land use for
economic and infrastructure development and so on.
The land use plans should clearly show the location of industrial corridors, special economic
zones, national projects, inter-provincial projects, heritage sites, religious and cultural sites,
academic institutions, security areas, disaster-prone zones, biodiversity-protection zones,
roads, health institutions, irrigation canals and other areas as designated by the government.
The act has provided for a land bank, which is itself a new concept in the country. Under the
concept, land belonging to various people will be pooled together and leased out to those who
are willing to invest in agriculture. The investors can even embark upon collective farming,
which will give a shot-in-the-arm to agricultural production and productivity
8.5.19 Consumer Protection Act, 2075

upon certain national and international provisions that are meant to promote children's rights.
Nepal's 2015 Constitution actually has an article dedicated to children’s fundamental rights - but
this new act translates these provisions and the children’s fundamental rights provided in the
constitution, into a legislative provision, which then allows children to exercise their rights
legally.

EIA Report 8-12 NEA-ESSD
The new Children's Act in Nepal is very different. It substantially differs from the earlier
children's act of 1992, as it recognises that children are entitled to these rights - and the state

social, biological and physical environment and should also elaborate utilization of local labour,
source of materials, benefits to the local people after the completion of the project, training to
local people in relation to construction, maintenance and operation, facilities required for
construction site and safety arrangements.
8.6.2 Water Resources Rules, 2050
It is mandatory under Rule 17(e) of the regulation that any person or corporate body, who
desires to obtain a license for utilization of water resources must state in his application that
appropriate measures will be taken to lessen the adverse effects due to the project on the
overall environment. Rule 19 stipulates that the water resources committee shall publish a
notice giving detail information about the project to the people.
8.6.3 Environment Protection Rules, 2054
The Environment Protection Rules (EPR) was endorsed in June 1997 and was made under the
provisions of the Environment Protection Act. The EPR has been amended several times. The
recent amendment states that TL projects of capacity above 132kV voltage level requires only
IEE unless it traverses through protected area, buffer zone or national parks. As, this TL travels
through protected area (National Parks), EIA is mandatory. The EPR adopts the environmental
assessment criteria mentioned in the EIA guidelines. However, the EPR establishes the
administrative framework for assessment, exhibition and determination of the EIA/IEE, in terms
of issues needed to be addressed and the format/layout of the EIA/IEE document.

8.6.8 Electricity Rules, 2050
Regulation on electricity sectors have been formulated for the implementation of the provisions
made in the Electricity Act, 2049. The Electricity Rules, 2050 emphasize environmental
analysis, which should include environmental mitigation measures to minimize adverse impacts
likely to occur while developing hydro-electricity (Rule 12 and 13). Rule 12 (f) and Rule (g) are
related to the EIA/ IEE process which emphasize that the EIA report should include measures
to be taken to minimize the adverse effects of the project on social, biological and physical
environment and should also elaborate utilization of local labour, source of materials, benefits
to the local people after the completion of the project, training to local people in relation to
construction, maintenance and operation, facilities required for construction site and safety
arrangements.
8.7 Guidelines and Working Procedures
8.7.1 National EIA Guidelines, 2050
The National EIA Guidelines, 1993 developed by the National Planning Commission in
conjunction with IUCN, set out the process for the environmental review and management of
infrastructure projects in all sectors and the respective roles of certain GoN agencies and
project proponents. The guideline was part of a comprehensive program to develop the national
and sectoral guidelines for establishing a national system for EIA which was part of GoN's
National Conservation Strategy. The schedules attached to the Guidelines include:
Schedule 1 : Projects requiring IEE Report
Schedule 2 : Projects requiring EIA
Schedule 3 : EIA based on project sites
Schedule 4 : Format for Terms of Reference
Schedule 5 : EIA Report Format
Schedule 6 : Format of EIA Report Annexes
It is mandatory to follow the National EIA Guidelines, 2050 (1993) during the EIA. Following the
guidelines, the environmental impact prediction and evaluation of the proposed project has
been done on physical, biological and socio-economic and cultural environment of the project
area. The guideline is used for analysis of significant issues.
8.7.2 EIA Guidelines for Forestry Sector, 1995
The GoN in keeping with the spirit of the National Environmental Impact Assessment
Guidelines, 1993 framed EIA guidelines for the forestry sector in 1995. The Guideline aim to
facilitate the sustainable use of forest resources for socio-economic development and meeting
basic need to the community regarding the forest products, to make proposals socio culturally
acceptable, economically feasible, and environmental friendly to conserve genetic resources
and biodiversity and minimize environmental damage in forest areas and facilitate in
identification of positive and negative impacts of programs to be implemented by other
agencies in forest areas. The guideline emphasized the need of carrying out an EIA/IEE of
development projects and programs proposed for implementation in forest areas.
8.7.3 Forest Production, Collection and Sales Distribution Guidelines, 2057
The Clauses 3 to 10 of the Guidelines have specified various procedure and formats for getting
approval for vegetation clearance, delineation of lands for vegetation clearance, evaluation of
wood volume etc. and government offices and officials responsible for the approval, delineation
and evaluation. These provisions have a direct relevance to the development of the project and
need compliance to these provisions. These provisions have a direct relevance to the
development of the project and need compliance to these provisions. It is obligation to the

project for getting approval in view of vegetation clearance and evaluation of wood volume from
division forest office prior to the construction phase.
8.7.4 Community Forest Guidelines, 2058
This guideline has been prepared by including amendments of acts, rules by officials of GoN
and related experts. Through these guidelines, persons involved in the development and
management of community forest like facilitators, User Groups, forester and managers etc. will
get help to understand about the process and stages of development of community forest.
Forest Users Group, forest officials, NGOs and INGOs are getting benefit by this guideline. Till
date, more than 15000 Community Forests have been handed over to the CFUGs.
8.7.5 Working Procedure and Standards for the Use of National Forest Land for
National Priority Project, 2076
Guideline for the use of forest area for development projects of National Priority projects
reiterates the use of the forest area only if other options are not available. The projects
requiring the forest land area have to make alternative studies to minimize the forest land use
areas. The proponent of the National Priority Project, National Pride Project, Priority
Transmission Line Project and Investment Allocated Project from Investment Board has to get
the approval from the Ministry of Forest and Environment.
The proponent of the project has to provide the land equal to the forest land permanently
occupied by the project to the ministry of forest and environment. The government project has
to make the provision of such land cost at its cost-estimate. Otherwise, Ministry of finance has
to provide such cost.
The proponent has to afforest the area equal to the forest area lost at minimum or the
proponent could deposit the required amount as per forest norm to the division forest office.The
proponent should plant 10 trees for every loss of tree and pole and look after the plantation for
5 years to ensure their protection and growth of every planted tree. Or the proponent deposit
the required amount for plantation and protection for five years to the DFO.
8.7.6 Order for Remission of Land Ceiling Exemtion, 2074 Nepal Government, Ministry of Land Reform and Management published a notice in Section 67
number 29 Nepal Gazette part 5 dated 2064/06/25, by using the authority given in Article 12 of
Land Reform Act 2021, containing the provision to purchase more than dissociated land by the
education or health institution, hydropower, cultural, industrial work, work for agricultural
industry and co-operative farming organization, if such industry or institutions need.

8.7.9 Hydropower Environmental Impact Assessment Manual, 2018
This Manual should be used in conjunction with the Nepal’s National EIA Guideline which
dictates the minimum standards, administrative systems and processes and templates to
befollowed during an EIA for any qualifying project. Where appropriate, good
internationalpractices have been included with this Manual to augment the standard EIA
approach, and assist hydropower project proponents in better defining environmental and social
risks, responsibilities and opportunities. Specifically, the Manual can be used at different
phases and fordifferent purposes for the preparation and review of EIAs for hydropower
projects. The Manual can be used for all types of hydropower projects that require an EIA
based on the Environment Protection Act and its regulations, particularly Schedule-2 of the
regulations. It aims to facilitate the EIA process for all hydropower projects such as run-of-river
(diversion and/or storage), storage reservoir and pumped storage facilities and associated
facilities of the project such as power transmission lines, substations, construction materials
management, and access roads.
The Manual outlines the approach for preparing, submitting, reviewing and implementing EIAs
related to hydropower in Nepal. Section 4 highlights stakeholder engagement and public
participation, section 5 and 6 is adhered to screening and scoping. Section 7, 8 & 9 related to
identifying, assessing and managing environmental and social impacts.
8.7.10 Forest Products, Collection, Sale and Distribution Directives,2073 The directives have specified various procedures and formats for getting approval for
vegetationclearance, delineation of lands for vegetation clearance, evaluation of wood
volume,etc. and government offices and officials responsible for the approval, delineation and
evaluation.These provisions have a direct relevance to the development of the project and
needcompliance to these provisions.
8.7.11 Community Forest Resource Inventory Guidelines, 2061 With the aim to assist Community Forest Users Group for sustainable forest management,
Community Forest Resource Inventory Guideline was prepared. The inventory guideline has six
chapters. Second chapter of the guidelin include forest resource inventory methodologies,
tools, sample size and intensity, resource requirement etc. Chapter three contains data
collection methodologies, sample design techniques and forest stock estimation techniques
including forest diversity. There is data analysis techniques and utilization of information
obtained from data analysis in chapter four and five.
8.8 Conventions
8.8.1 Convention on Biological Diversity, 1992
The convention contains a series of far reaching obligations related to the conservation of
biological diversity and sustainable uses of its components. One of these obligations is the
requirement for environmental study. The purpose of an environmental study in relation to
biodiversity conservation is to identify in advance:
• The aspects of the project which is likely to have significant adverse effects on biological diversity
at genetic, species and ecosystem level, and
• The steps to be taken to avoid or minimize significant adverse effects to ensure that the
proposed project comply with existing environmental legislation
The GoN has included 17 species of plants and 39 species of wild animals in the protection
list.If the project area is in the core habitat of these species and project activity will likely to
affect them, mitigation measures shall be proposed and be implemented to avoid and/ or
mitigate the adverse impacts. Nepal is a party to the convention of Biological diversity and in
Andhikhola Storage HEP (180MW) Review of Policies and Legal Provision
EIA Report 8-17 NEA-ESSD
accordance to the article 14, adequate attention should be given to minimize and or avoid the
impacts.
8.8.2 Convention on International Trade in Endangered Species of Wild Fauna
and Flora (CITES), 1973
Nepal became a signatory state to the Convention on International Trade in Endangered
Species of Wild Fauna and Flora (CITES) on June 18, 1975. That aims to control the trade of
certain wildlife species to prevent further endangered species of their survival. CITES classified
species according to the following criteria: a) Species threatened with extinction, b) Species
which could become endangered and c) Species that are protected.
As Nepal is party to the convention related to species conservation, attention should be given to
evaluate the impacts of the project activities on meeting their obligation. It is relevant to EIA that
species protection list could also be used to evaluate the significance of the identified and
predicted impacts. Plant and wild animal species under legal protection provides a basis to
purpose EMPs for their conservation and for least damaging them during project
implementation.Nepal is signatory to this convention, which classified species according to
criteria where access or control is important (eg. I-species threatened with extinction; II-species
which could become endangered; III-species that are protected).
8.8.3 ILO Convention of Indigenous and Tribal Peoples (No.169)
Nepal ratified International Labour Organization (ILO) Convention No. 169 on September 14,
2007. In 2007 the UN Declaration on the Rights of Indigenous Peoples was adopted by the
General Assembly. The declaration reaffirms the importance of the principle and approaches
provided for under Convention No. 169 and its adoption therefore provide a fresh impetus for
promoting the ratification and implementation of 169. ILO Convention No. 169 highlights the
need to recognize indigenous and tribal people’s specific knowledge, skills and technologies as
the basis for their traditional economies and self-determined development process.
Article-1 of the convention provides definition of the tribal indigenous people. Article-6 deals the
consultation of the people concerned through appropriate procedure in particular through their
representative institutions. Whenever, consideration is being given to legislative or
administrative measures which may affect them directly.In Article 15, the rights of the people
concerned to the natural resources pertaining to their lands shall cover the total environments
of the areas which the people concerned occupy or use. The peoples concerned shall wherever
possible participate in the benefit of such activities and shall receive fair compensation for any
damage which they may sustain as a result of such activities. Article 16 (2) clearly mention that
where the relocation of these peoples is considered necessary as an exceptional measures
such as relocation shall take place only with their free and inform consent.
Where their consent cannot be obtained, such relocation shall take place only following
appropriate procedures established by national laws and regulations, including public inquiries
where appropriate, which provide the opportunity for effective representation of the peoples
concerned. Article 16 (3) mention that whenever possible these peoples shall have the right to
return their traditional land as soon as the grounds for relocation cease to exist. Article 16 (5)
elaborated the persons thus relocated shall be fully compensated for any resulting loss or
injury. The ILO Convention on Indigenous and Tribal Peoples, 1989 (No.169) is relevant for the
proposed project as there are indigenous and tribal families in the project affected area. The
project will acquire and utilize most of the natural resources belonging to those families. Hence,
the project has obligation to have consultation and taking consensus from them before the
implementation of the project.
Andhikhola Storage HEP (180MW) Review of Policies and Legal Provision
EIA Report 8-18 NEA-ESSD
Article-15 states that the rights of the people concerned to the natural resources pertaining to
their lands shall be specifically safeguarded. Provision includes the people to participate in the
use, management and conservation of these resources. This provision creates some confusion
and ultimately brings conflict between the project proponent and resources owners. Project
share distribution and employment priority to these people will somehow reduce the possible
conflict. The provision made in the ILO Convention on Indigenous and Tribal Peoples, 1989
(No.169) is not line fully with the prevailing acts and rules regarding environmental study of the
proposed project.
8.9 Standards 8.9.1 National Ambient Air Quality Standard, 2069 The National Ambient Air Quality Standards, 2012 enforced by GoN has set maximum
concentration limit for nine air quality parameters. These parameters includes total suspended
particles (TSP), particulate matter (PM10), sulfur dioxide, nitrogen dioxide, carbon mono-oxide,
lead, benzene, PM2.5 and Ozone. The standards has also prescribed the test methods for these
parameters. The project during its construction and operation will have to comply with set
standards for the ambient air quality.
8.9.2 Nepal Vehicle Mass Emission Standard, 2069 In order to regulate the vehicular emission, GoN released the Nepal Vehicle Mass Emission
Standard, 2069. This standard has set the limit values on different parameters of emission for
petrol and diesel fueled vehicles. These parameters include carbon monoxide, hydrocarbon,
oxides of nitrogen particulate matters (PM) and smoke opacity. Furthermore, these standards
are based on type approval and conformity of production of the vehicles.
8.9.3 National Ambient Sound Quality Standard, 2069 It has set the limit of allowable noise/sound intensity in different areas at different time, during
the day and the night. The limit of sound intensity is different for different area like industrial
area, commercial area, settlement areas in rural and urban settings, etc. These standard will be
complied.
8.9.4 Standard on Emission of Smoke by Diesel Generators, 2069 Emission standards are set for the new and existing diesel generators by the GoN. The
standard has set the limits on four parameters of emission including Carbon monoxide (CO),
hydrocarbon (HC), oxide of nitrogen (NOx) and Particulate Matter (PM). This standard is set in
accordance with the EURO III and Bharat III standards. The generators to be used during
project construction will follow these standards.
8.10 Province Level Laws and Policies Gandaki Province has issued some guidelines and policies related to environment and use of
natural resources. As the proposed AKSHEP lies in Gandaki Province, it is worthwhile to review
these guidelines.

This working procedure requires the local bodies to prepare a work plan on annual basis to
designate the areas for excavation and collection of construction materials including sand and
aggregates. The local bodies are further required to carry out the environmental assessment
(IEE or EIA) as per existing laws prior to collection of construction materials.
Andhikhola Storage HEP (180MW) Review of Policies and Legal Provision
EIA Report 8-19 NEA-ESSD
For any excavation and collection of construction materials from the protected areas (National
park, wildlife reserve, conservation areas), the concerned protected area office need to prepare
the annual plan and carry out environmental assessment. Further this working procedure has
also restricted the collection of construction materials from Asar 1 to Bhadra 15. Similarly, in the
remaining time period of the year, the excavation, and collection is restricted in the nighttime.
Similarly, for national or province priority projects and other community construction works, the
local bodies can provide the required construction materials from their administrative
boundaries by charging tax or royalty based upon the existing rates.
Andhikhola Storage HEP (180 MW) Environmental Management Plan
EIA Report 9-1 NEA-ESSD
9 ENVIRONMENTAL MANAGEMENT PLAN
9.1 Introduction This chapter on environmental management, monitoring and audit is formulated in accordance
with Nepalese EIA requirements. The plan specifies the environmental responsibilities of all
parties involved in the project and detail the environmental management requirements of the
project during the pre-construction, construction and operation phases. The project proponent
will be responsible for the implementation of the EMP. The plan will apply adaptive
management to accommodate changes in project design during the time. As there is
uncertainty in predicting impacts and effectiveness of mitigation measures, the EMP is
proposed as a plan that will be revised periodically during pre-construction, construction,
operation and maintenance phases. The EMP will be updated during the final design to cover
the likely changes in project design, likely changes in policy and regulatory mechanism and
stakeholder concerns.
9.2 Objectives of EMP The principle objective of the EMP for AKSHEP is to formulate a framework for ensuring that all
mitigation measures identified in Chapter 7 are implemented and to provide a basis for
examining whether the mitigation measures are effective after implementation. In this context
the EMP refers to the project management, monitoring and auditing actions required to ensure
compliance with environmental laws and to reduce or eliminate adverse impacts and enhance
environmental opportunities.
The EMP is an environmental operation manual for use by management and staff employed on
the project, and will serve as an advisory document to regulatory authorities such as
MoEWRIand MoFE. The plan specifies the agency responsible for mitigation and how it will co-
ordinate with various line agencies. The EMP has the following objectives:
• define environmental management principles and guidelines for design, construction and
operation of the project;
• establish the roles and responsibilities of all parties involved in project environmental
management;
• describe mitigation measures that shall be implemented to avoid or mitigate adverse
environmental impacts;
• formulate environment management framework to ensure the implementation of mitigation
measures and monitoring programs; and
• establish a supervision, monitoring, auditing and reporting framework.
9.3 Environment Legislation The EPA, 1997 and EPR, 1997 are the main umbrella legislations in Nepal. The MoFE is the
lead agency, which administers the environmental matters emphasizing on environmental
conservation and management through internalizing environmental assessment, pollution
control and prevention, conservation of natural heritage sites, compensation for environmental
damages, etc. However, there are several other policies, guidelines, acts and rules which relate
to construction and operation of AKSHEP and will comply with the provisions by the involved
parties during the period.
9.4 Environmental Management Plan This EMP has two components; the environmental management activities and the activities
implementing organ.
Andhikhola Storage HEP (180 MW) Environmental Management Plan
EIA Report 9-2 NEA-ESSD
9.4.1 Environmental Management Activities
The environmental management activity is a synthesized plan incorporating the elements of
environmental mitigation and enhancement measures. The environmental mitigation and
enhancement measures are bundled in a series of activities in the project life cycle. The
environmental management actions for the project is broadly described in the following
headings; Permits and Approval Plan, Resettlement and Rehabilitation Plan; Public Health and
Safety Management, Environmental Enhancement Plan, Project Information Management Plan,
Public Grievances Redress Management Plan, Institutional Capacity Strengthening Plan and
Pollution Abatement Plan. The elements stipulated in above plans go hand in hand throughout
the project life cycle.
9.4.1.1 Permits and Approval Plan
The objective of permits and approvals is to comply with the government legislative mechanism
and to keep cordial relationships with the project stakeholders. There are a number of
legislative provisions which require prior permits and approvals from the concerned government
agencies to commence the work. As per EPR, 1997 the project proponent will have prime
responsibility for the implementation of EMP. The EPA and EPR made provisions for the
compliance of EIA report. The implementation of EMP will be guided by GoN policies and legal
framework. Land Acquisition Act, 2034 (1977) regulates the land acquisition and compensation
determination process. Similarly, Forest Act, 2076 and Regulations 2051 (1995) regulates
forest clearance required for the project. There are other Acts, Rules and Policies which directly
or indirectly regulate the environmental activities of the project.
Besides, some activities would require general consensus of the project area communities or
individuals for smooth operation of certain activities of construction and operation without
hindrance. In these cases project management should take prior permits and approvals or
consensus of the people or individuals before the start of the activities. The project should
ensure that all the permits and approval or consensus of the general public is taken before the
start of the activities. Permits and approval required for the project are presented in the table
given below.

9.5 Environment Management Approach During the planning and pre-construction phase, the prime responsibility for the environment
management is with NEA as the proponent of the Project. NEA has however, delegated the
authority to ESSD in following up the national approval process of the EIA process. This
department will be responsible for the overall control of social management program of the
Andhikhola Storage HEP (180 MW) Environmental Management Plan
EIA Report 9-7 NEA-ESSD
project. This department will also be responsible for the coordination of work of the project at
central level management of NEA and central line agencies. It is proposed that ESSD will
implement monitoring program and some of the social mitigation. The mitigation and social
support program will be implemented by mobilizing local NGOs, Consulting firm Contractor and
line agencies.
9.5.1 Pre-construction Phase
The EMP for preconstruction phase will include land acquisition and compensation, public
concern issues, Stakeholder Engagement Plan and Indigenous Peoples Development Plan, co-
ordination with line agencies and local NGOs and INGOs. The allocation of adequate budget for
the implementation of preconstruction measures, follow up for contract clauses that needs to be
incorporated in tender documents are the other activities to be managed or conducted during
the pre-construction phase. The ESSD of NEA will have the prime responsibility for dealing with
preconstruction issues. During this phase a CDC will be formed to deal with all the
compensation matters.
9.5.2 Construction Phase
This phase is the most critical as it requires expertise and resources to manage the
construction phase impacts. It includes implementation of the suggested mitigation measures
outlined in Chapter VII with the EMP as a vital tool and is dependent on liaison with local line
agencies, NEA central office and other line agencies. The project proponent will be responsible
for carrying out the requirements for mitigation, implementing, and monitoring the EMP,
Stakeholder Engagement Plan, water-use management plan and Indigenous Peoples
Development Plan through an approach to be formulated by them. The detail of the water-use
management plan is given in Table below.
9.5.3 Operation Phase
An environment unit will be formed, for the first two years of operation, under the Plant Manager
for the monitoring during the operation phase which will also be responsible for implementing
the environmental mitigation measures of the AKSHEP. This unit will have representatives from
ESSD of NEA. The proponent will provide the cost required for the implementation of the
operation phase environmental management program.
9.6 Management Plan for Downstream and Upstream Water User
9.6.1 Downstream Water User
Kaligandaki ‘A’ HEP owned by Nepal Electricity Authority (NEA) is the immediate downstream
water user of Andhikhola from proposed dam site. This hydropower is located about 2.5km at
downstream of proposed dam site. Due to the implementation of proposed storage hydropower
project, existing Kaligandaki “A’ HEP will receive reduced amount of water from Andhikhola
river as shown in Table 5-2. Proposed storage Hydropower need to compensate for retaining
water contributed by Andhikhola to existing Kaligandaki ‘A’ HEP Thus, recommended
management plan is presented in table 9-6.
Andhikhola Storage HEP (180 MW) Environmental Management Plan
EIA Report 9-8 NEA-ESSD
9.6.2 Upstream Water User
a. Hydropower Project:
Andhikhola hydropower project owned by Butwal Power Company (BPC) is the water user at
upstream of dam site which will be inundated with the implementation of proposed storage
project. As per the power purchase agreement (PPA) between NEA and BPC, if NEA
constructs Andhikhola Storage HEP, BPC will not get any kind of compensation for the
inundation of headwork structure of existing Andhikhola HEP and other loss related to energy
and revenue. However, if BPC wise to continue to operate existing hydropower, it can modify or
relocate the intake site with its own cost without any additional cost to the NEA. Thus, there
exist two case scenario for BPC; first, continue to operate existing HEP with modification of
intake and second, terminate to operate existing HEP.
If BPC does not wise to continue to operate existing hydropower, but Andhikhola Storage HEP
wise to continue to operate, AKSHEP can modify the intake structure of existing HEP with its
own cost and can operate. Thus, for these case scenarios, the recommended management
plan is present in table 9-6
b. Irrigation Scheme operated by AKWUA
Irrigation scheme operated by AKWUA is another water user at upstream of dam site. The
irrigation system provides irrigation facility for a total land area of 500ha in Syangja and Palpa
district. Water user’s organization Andhikhola Water User Association (AKWUA), has been
formed for the regular operation and management of the irrigation system. The irrigation
scheme acquires water from Andhikhola through headrace tunnel of existing Andhikhola HEP
to the shaft site from where water is diverted to open canal for irrigation purpose. Thus, with the
implementation of project, intake of existing hydropower will be inundated which will not only
effect hydropower but also for irrigation scheme.
EIA recommend for continue supply of water for irrigation scheme. Thus, there exist two case
scenario for irrigation project; first, continue to supply water from modification of existing
structure; second, construct new structure to supply water for irrigation scheme. For these
cases, management plan has been present in table 9-6.

PMO will be responsible for the distribution of report to the concerned agencies. The AK-EMU
will prepare the following reports.
9.7.3.1 Pre construction Environmental Report
This report will be prepared prior to (just before) start of construction work. The report includes
the changes in baseline situation and site condition prior to start of actual construction work.
The EMP will be updated during this period as required.
9.7.3.2 Construction Phase Environmental Report
The construction phase environmental report will be prepared on quarterly basis and annual
environmental report will be prepared at the end of each calendar year. A final environmental
report will be prepared after the completion of the construction work. AK-EMU will be
responsible for the preparation of report. The report will be distributed to MoFE, MoEWRI,
DoED and district level line agencies.
9.7.3.3 Operation and Maintenance Phase Environmental Report
Operation and maintenance phase environmental report will be prepared for the two years
following the construction. AK-EMU will prepare this report for project. The report will describe
mitigation measures, problems and recommended solution. The report shall clearly identify
where operational mitigation measures are not being met or where mitigation efforts are
inadequate to protect natural and socio-economic resources. Unanticipated deleterious impacts
of the project will be identified. Measures to solve problem will be proposed and be funded
under the project annual operating budget. Environmental audit report will be prepared by
MoFE as per EPR, 2054.
9.8 Environmental Monitoring This section discusses the environmental monitoring programs likely to be associated with the
implementation of the EMP for AKSHEP. It also assists to ensure compliance with
environmental laws and in ameliorating or eliminating adverse impacts.
9.8.1 General Rationale for Environmental Monitoring
It is not enough to simply formulate mitigation measures and then assume there will be timely
and effective implementation. The need for monitoring of the Project's handling of its
procedures is equally valid for ecological, physical, construction methods and socio-economic
subject matters. This general rationale for carrying out serious monitoring is exemplified below
by discussing the socio-economic aspects of monitoring.Environmental monitoring is required
to ensure compliance of the mitigation and enhancement program, tender clauses related to
environment and social issues and to assess the actual impacts of these measures as well as
the emerging impacts during different phases of the project. For instance, the complexities of
dealing with individuals and communities at a fundamental economic, cultural and social level
necessitates that there is constant feedback between those charged with administering the
compensation schedule and the intended beneficiaries. Such monitoring should include, though
not necessarily be limited to, the following points:
• Disbursement of compensation should take place promptly and according to agreed
procedures/rates
• Community gain procedures are implemented and are in harmony with wishes of locals.
Local people are hired wherever possible as per the contractor's obligation (subject to
limitations enforced by skill levels, etc.)
Andhikhola Storage HEP (180 MW) Environmental Management Plan
EIA Report 9-16 NEA-ESSD
• Rates of disease infection are monitored to highlight any increases, particularly in STDs
which may indicate that prevention and awareness campaigns need to be extended
When assigning environmental cost, the Project Proponent will make allowance to fund both
physical monitoring of the Project Proponent and its sub-contractors and also socio-economic
monitoring of the compensation process of individuals, families and communities affected.
Effective monitoring of the whole project cycle, particularly the resettlement related aspects, will
assist in the identification of unexpected problems/outcomes, and facilitate the correction of
these. Monitoring of socio-economic impact indicators should wherever possible be
participatory, involving local groups assessing their own situations as part of the process. This
will assist local communities raise their awareness about their situations and the chain of
causality bringing about their situations of relative gain or loss. This shared understanding will
help provide the instruments with which solutions may be devised.
Social monitoring should also be incorporated in the scope of work for construction
management, so that the local labor recruitment norms and requirements, their operating
conditions, rights and penalties as well as access and use of health and social service facilities
established in the Project's contracts can be closely observed in order to avoid inequities and
conflicts. Social monitoring is the most effective if local community leadership and
administration structures are involved in a process that is participatory, and provides recourse
to recognized authority structures. Involving community leaders and local authorities often
provides the means to resolve social problems identified in a direct, efficient and effective
manner.
Social monitoring of labor conditions and the impacts of Storage project and resettlement of
families should identify the particular benefits and losses accruing to women. Their position in
the socio-economic development of the area is crucial, and their responsibilities for family
welfare, most of the subsistence agricultural cycle, as well as minor income generating
activities should be verified through participatory monitoring exercises. Participatory monitoring
can facilitate the growth of confidence of participants simply by their acquisition of knowledge
about their situation. In addition, it permits participants to immediately initiate actions to improve
their circumstances, since they do not have to wait to learn the results of an external monitoring
mission as so commonly occurs. Feedback provision and involvement of local people in
decision-making are pre-requisites to the fostering of goodwill between them and the
construction agencies.
9.8.2 Objectives of Monitoring
Environmental monitoring is carried out with the following objectives;
• to ensure compliance of mitigation and enhancement program, tender clauses related to
environment and social issues,
• to assess the actual impacts of these measures as well as the emerging impacts during
different phases of the project,
• to comprehend environmental condition in project area prior to implementation of project;
• to ensure compliance status of implementation of mitigation measures and regulatory
standards;
• to ensure the effective compliance of tender clauses as per contract document;
• to check the effectiveness of mitigation and enhancement measures implemented by
different project parties; and
• to verify the accuracy of EIA predictions and assess the emerging and cumulative
environmental problems.
Andhikhola Storage HEP (180 MW) Environmental Management Plan
EIA Report 9-17 NEA-ESSD
9.8.3 Requirements for Environmental Monitoring in Nepal
Monitoring is an essential aspect of environmental management. It consist collection of data to
measure environmental changes associated with construction and operation of the project.
MoEWRI/MoFE is the responsible agency for the environmental monitoring of energy sector
projects as per EPR, 2054. Likewise Rule 12 states that proponent shall comply with the
matters mentioned in EIA report. Manuals and Guideline prepared by line ministries are
available which define the monitoring mechanism.
The National EIA Guidelines (2050) and the EPR, 2054 specify, in general, the requirements for
environmental monitoring as needed to assess the actual effects and ensure compliance of the
implementation measures during project construction and operation. Identification and/or
quantification of the degree of impacts on the existing environment by developmental activities
enable the adoption of appropriate mitigation measures. This engenders the society’s ability to
reduce or minimize detrimental effects on the environment and human life and enhance
opportunities for improved standard of living. An Environmental Monitoring Plan will be required
to define the responsibilities for the monitoring, the parameters that will be monitored, where
the monitoring will take place and its frequency.
9.8.4 Site Inspections
ESSD will conduct site inspection prior to construction, AK-EMU during construction and at the
end of construction. The inspection will be coordinated with contractor(s).The site inspections
will be conducted as:
9.8.4.1 Initial Inspection
The initial inspection conducted during pre-construction will document the site condition just
before start of construction work. Necessary standard for construction and required
environmental control based on the available national and international practices will be
established. Visual documentation of the site and photographs will be taken during the
inspection.
9.8.4.2 Progress Inspection
The progress inspection during construction will document the compliance and impact
monitoring at particular site. The purpose of inspection will be early identification of
environmental and social problems and propose suitable remedial measures. The monitoring
will be conducted daily, weekly and monthly basis for the parameters like vegetation clearance,
spoil disposal, health and sanitation and safety satiation. The contractor will be formally notified
through letter of Project Manager/Supervising Consult for remedial action if any deficiency is
noted during monitoring.
9.8.4.3 Final Inspection
The final inspection will be conducted at the end of construction phase to document the
contractors compliance of tender clauses related to environment. The contractor will be given
written notice, if cases of non-compliance or partially compliance are found during inspection.
9.8.5 Environmental Monitoring Plans
Environmental monitoring is required to ensure compliance of the mitigation and enhancement
program, tender clauses related to environment and social issues and to assess the actual
impacts of these measures as well as the emerging impacts during different phases of the
project a monitoring program, required for the project to evaluate the application and
effectiveness of mitigation measures, is formulated in three phases.
Andhikhola Storage HEP (180 MW) Environmental Management Plan
EIA Report 9-18 NEA-ESSD
9.8.5.1 Baseline Monitoring
The primary concern during this phase will be to implement field data collection programs
needed to enhance the knowledge of baseline conditions. Focus will be on the gathering of
scientific and sociological information needed to verify and update the data provided by this EIA
process. The land acquisition, compensation, rehabilitation measures will be disclosed to
people and common consensus will be made. It will be ensured that mitigation and monitoring
requirements associated with contractor are dually incorporated in tender document and
contract agreement.
9.8.5.2 Compliance Monitoring
The compliance monitoring will be conducted to monitor compliance of the proposed mitigation
measures and monitoring activities. The compliance monitoring will mainly focus on;
• compliance of the tender clause;
• compliance of the mitigation measures;
• timely and adequately implementation of Environmental Management Plan and
• overall environmental and social performance of the project.
In this monitoring, the GoN licensing entity (MoEWRI/DoED) oversees and ensures the
implementation of the required mitigation measures according to GoN guidelines and approved
mitigation plan. The AK-EMU will be delegated the day-to day responsibilities in this respect.
This monitoring will be conducted during project construction as well as operation phase.
9.8.5.3 Impact Monitoring
Impact monitoring will be carried out to assess actual level of impact due to project
construction. The impact monitoring includes:
• monitoring of the impacts of the project on physico-chemical, biological and
socioeconomic and cultural environment of the area;
• monitoring of the accuracy of the predicted impacts;
• identify the emerging impacts due to project activities or natural process and develop
remedial action; and
• monitoring of the effectiveness of mitigation measures
This monitoring will be conducted during project construction as well as operation phase. The
monitoring of the AKSHEP will include:
Physical Environment
• Watershed monitoring /Land use
• Stability of the area around the reservoir area and other project components
Biological Environment
• Forest Clearing
• Re-vegetation and slope stabilization
• Wildlife
Socio-economic and Cultural Environment
• Employment monitoring
• The economic status of the affected people and relocated people
• Adaptation of resettled households to their new homes and communities
• Public safety and security monitoring
• Health and sanitation monitoring
• Compensation
The full Environmental Management Program will be elaborated during the construction phase
of the project, reflecting the final design and alignment considerations made by the project.

9.9 Environmental Audit Framework The Environmental Audit (EA) shall be carried out to assess environmental impacts, accuracy
of predictions, the effectiveness of mitigation measures and the monitoring plan. It is intended
that EA should relate actual impacts with predicted impacts which help in evaluating the
accuracy and adequacy of EIA predictions.
9.9.1 General Rationale for Environmental Audit
The term audit has been transferred from the language of finance to EIA as it effectively
describes the process of examination and assessment of performance necessary in the
analysis of overall efficiency and target attainment, whilst also helping to ensure that mistakes
identified in the present are not destined for repetition in future.
The role of the environmental auditor, therefore, is to identify environmental change arising
from the Project and to assess the effectiveness of the mitigation measures adopted,
suggesting additional measures where appropriate. In addition, auditing of the Project will
indicate where initial predictive methods were weak or environmental knowledge lacking, thus
indicating areas where further research or attention to detail may be necessary. Additionally,
close liaison with the implementing agency will secure valuable insights into the EIA process
and strengthen the capacity of the agency. Thus, an environmental audit provides snapshot of
environmental situation, compliance or impact with documented evidences. Besides fulfilling the
formal requirements environmental audit is a good tool to promote environmental best practices
and procedure. In general environmental auditing is done with the following aim:
• assessing compliance with formal requirement;
Andhi Khola Storage HEP (180MW) Public Consultation
EIA Report 9-26 NEA-ESSD
• facilitating management control of environmental practices;
• promoting good environmental management and minimizing the risks; and
• establishing the performance baseline for an environment management system.
9.9.2 Environmental Audit in Nepal
Environment Protection Rules, 1997, Article 14 specifies that an EA is required after two years
of project operation. Auditing refers to a general class of environmental investigations that are
used to verify past and current environmental performance. In the context of the environmental
management of a project in Nepal, environment impact auditing assesses the actual
environmental impacts, accuracy of predictions, effectiveness of environmental impact
mitigation and enhancement measures, and functioning of pre-construction, construction and
operation phase monitoring mechanisms.
9.9.3 Types of Auditing
The National EIA Guidelines, 1993 has stated the following types of audit that may be carried
out for large scale development project.
a) Decision Point Auditing: Examines the effectiveness of environmental impact assessment
as a decision-making tool.
b) Implementation Auditing: Ensures that the condition of contract has been fulfilled.
c) Performance Auditing: Studies the work of agencies associated with project management.
d) Participatory Auditing: Ensure that stakeholder participation and expectation has been
met.
e) Predictive Technique Auditing: Examines environmental changes arising from project
implementation.
f) EIA Procedure Auditing: Examines critically the methods and approaches of the auditing
assessment procedure adopted during the EIA.
9.9.4 Agencies Responsible for Auditing
The National EIA Guidelines specify that EA must be carried out by the government agencies
approving the project with the assistance of relevant government agencies and NGOs as
necessary. The guideline also stated that result obtained from the EA should be made available
to the project proponent and concerned agencies. The MoFE will carry out environmental
impact audit of the project. Local NGOs may also be entrusted to carry out the task, if they are
engaged to do so by the government. The auditing shall focus on impacts of forest clearance,
compensatory plantation, geological condition, status of affected people, land-use pattern,
infrastructure development, etc.
9.9.5 Auditing Parameters, Schedule and Agencies to be consulted
The detail of auditing parameters, schedule, location, method, indicator and agencies to be
consulted are presented in following tables. The environmental auditing shall include but not be
limited to following tasks.
• Changes in physico- chemical, biological, socioeconomic and cultural environment
baseline condition after the project construction;
• Accuracy of the predicted impacts;
• Magnitude of the predicted impacts;
• Effectiveness of the proposed mitigation measures;
• Compliance of the recommendations and findings of EIA report;
• Compliance of the tender clauses;
• Identification of number and area on non-compliance; and

10 PUBLIC CONSULTATION
10.1 Introduction The public consultation process involve visiting the areas affected by the proposed storage
project, identifying the stakeholders, consulting with them with the objectives of the project,
gathering their views and opinions regarding the projects. The involvement of the public from
the conceptual stage of the project is essential for the success of any development activities.
Public consultation and information disclosure from the beginning is also important to reduce
misunderstandings and successful implementation of a project. It is a process of both
information giving and listening issues and concerns of public for planning and successful
implementation of the project with full support of the stakeholders. Therefore, the project has
given high emphasis to public consultation and information disclosure throughout the EIA
process.
The National EIA Guidelines states that public involvement is one of the main parameters for
the success of any development project. The EPR, 2054 also makes it mandatory for holding
one public hearing in the affected Rural Municipality or Municipality. This section discusses and
outlines the consultation carried out with the local people and other stakeholders. It also gives
all the government and the public consultations that have taken place during the course of the
EIA.
Similarly, as per EPR, 2054 public involvement is mandatory during the Scoping for EIA of any
proposal. The EPR, 2054 specifies that "In regards to any proposal requiring EIA, the
proponent shall publish a notice in any national level daily newspaper, affixing the notice in
Rural Municipality or Municipality, where the proposal is to be implemented, as well as the
schools, hospitals, health posts and concerned individuals or institutions of that area, to offer in
writing their suggestions concerning the possible impact of the implementation of the proposals
on the environment within a 15 day time period". It further states after the publication of the
notice "anyone who wishes to offer his opinion and suggestion in that connection may offer his
opinion and suggestions to the concerned proponent within 15 days from the date of publication
of such notice…" The object of this rule is to inform the public of proposed project development
and provide a reasonable time to gather their concerns, comments suggestions and
recommendations concerning potential project impacts.
10.2 Approaches for Public Involvement
10.2.1 Public Consultation during Scoping Phase
A public notice was published in national daily newspaper "Gorkhapatra" on 2074/05/20 for the
scoping study. The main objectives of the notice were:
• To inform the public about the project itself and the area to be affected
• To request the concerned people, organization, NGOs and RMs/Municipality to send
comments and suggestions regarding the project.
After the publication of the notice, the team visited for the Scoping exercise. The suggestions,
comments and information received from all the affected people, organizations, NGOs and
RMs/Municipality offices during the Scoping phase have been incorporated while preparing the
report.16 meeting along with 181 participants were involve in that meeting.

10.2.2 Public Consultation and Participation during EIA
Public consultation during EIA involved formal and informal discussions with a range of district
and local level stakeholders. HH survey of the directly project affected HHs and informal
meetings/consultations with key stakeholders of the project area were used as the main tool of
community consultation and information dissemination for preparation the EIA report. During
the consultations, the participants were requested to express their views, concerns/issues
regarding the project as well as they were informed regarding the project and its activities.
Information such as project purpose, project type, impact area, likely impacts and potential
opportunities due to project implementation were provided to the people during the
consultation. Checklists and questionnaire were developed to facilitate the KIIs and HH survey.
During the field survey, emphasis was placed on consultation with affected communities and
people living in adjoining areas, to inform them about the proposed project and give them an
opportunity to express their views. 30 meeting along with 664 participants were involve in EIA
phase meeting.

Andhikhola Storage HEP (180 MW) Conclusion
EIA Report 11-1 NEA-ESSD
11 CONCLUSION
The EIA study has identified environmental and social issues of the proposed AKSHEP and
predicted likely adverse and beneficial impacts due to its implementation. The project requires a
large area of land belonging to a number of families. Therefore, land acquisition, resettlement
and its consequences are the most critical and serious issues affecting socio-economic
conditions of local people. Physical and biological impacts are moderate and within acceptable
limits. On other hand, proposed project is a big opportunity not only to local area but also to
Gandaki province and Nepal.
11.1 Physical Environment
• The project will acquire a total area of 913.00 ha of land permanently for the project structures. Moreover, about 52.82 ha land will be required for temporary use during the project construction. Land use change, land erosion, change in natural river flow regime, air, water and noise pollution, and others are likely physical impacts in the project area due to the project construction.
• Various preventative and corrective measures have been proposed for mitigation. Most of them should be integrated in BoQ of contract document of the project.
11.2 Biological Environment
• The major impacts on vegetation and forest resources include the loss of 8192 trees of different species from 17.76 ha of National forest land. In addition, 221 thousands trees including fodder and fruits tree need to be felled from private land. Compensatory plantation and training on forest management to the CF users have proposed as mitigation options.
• Release of 10 percentage of minimum monthly flow will be provisioned at the dam spill way to ensure the integrity of the aquatic ecosystem in the downstream dewatered stretch of Aandhikhola. Fish hatchery program is proposed to maintain fish population in Aandhikhola after the dam construction.
11.3 Socio-Economic & Cultural Environment
• In terms of the loss of land acquisition, 1200 households will be affected due to the implementation of the project.
• At the time of EIA field survey, 712 private structures (house, shed etc) and 24 community structures (school, temple, bridge etc) needs to be relocated from the proposed reservoir area.
• The proposed project will affect existing Aandhikhola Hydroelectric Plant (9.4 MW) and irrigation system which are using water from Aandhikhola.
The total environmental cost including compensation to private land and properties is estimated
to be NRs 17,647,413,483/- The total environmental cost amounts to approximately 31.51% of
the total project cost (NRs 56 Billion). The EIA study concludes that the proposed Aandhikhola Storage Hydroelectric Project (180 MW) shall have significant impacts on socio-economic & cultural environment, as well some impacts on physical and biological environment of the project area, but all these impacts can be mitigated and compensated. thus this project can be socially acceptable and environmentally feasible.
