EXECUTIVE SUMMARY

INTRODUCTION

As a fuel, natural gas competes with a range of alternative products such as coal and lignite as well

as petroleum products such as liquefied petroleum gas, naphtha, high speed diesel, light diesel oil

and fuel oil. However, due to lower fuel operating costs and better combustion characteristics, natural

gas has distinct economic advantages over other sources of energy. In addition, natural gas has

substantial environmental advantages over other energy sources, due to lower emissions.

The development of proposed project is for natural gas transportation within state of Gujarat. The

proposed project is planned to be developed by M/s Gujarat State Petronet Limited (GSPL) India.

M/s GSPL, a Group company of GSPC is one of the leading company in the field of Natural Gas

transmission line. It is in the process of establishing & expanding its pipeline network all over the

Gujarat State to take care of future demand-supply gap of natural gas to fulfill the requirements of

various consumers throughout Gujarat. It is first company in India to transport natural gas on open

access basis and is a Pure Natural Gas Transmission Company.

GSPL is a pioneer in developing energy transportation infrastructure and connecting natural gas

supply basins and LNG terminals to growing markets. The company has developed requisite

expertise and confidence with proven project management competencies.

GSPL proposes to lay a pipeline for the supply of Natural Gas from Anjar to Chotila. The proposed

Anjar to Chotila Pipeline will originate from village Ratanpar-(GSPL's ARPL SV-8 TOP- 8), Taluka-

Sayla & district Surendranagar of Gujarat State . Pipeline stretch will cover a distance of 196.14 km,

and runs through Surendranagar, Morbi & Kutch regions and terminates at GSPL's Dispatch station

at village Rata Talav, Taluk Anjar & district Kutch of Gujarat State.

M/s. Gujarat State Petronet Limited (GSPL) has received the Authorization from PNGRB (Petroleum

and natural Gas regulatory Board) for the transportation of natural gas with a permissible RoU width

along the pipeline route.

PROJECT DESCRIPTION

The proposed underground Natural Gas Pipeline project is of approx. 196.14 KM stretch from Anjar

to Chotila with associated facilities such as Sectionalized valve Stations /Tap-off/Metering

/Receiving/ Dispatch/Intermediate Pigging stations. The Proposed alignment also meets the other

broader requirements of laying criteria of the pipelines. Accordingly, the present pipeline route has

been selected for the transmission of natural gas to various parts of Gujarat.

Cost of Project

The total estimated expenditure for laying of Anjar-Chotila pipeline project is approx. Rs 1058.40 Crores.

Need of Project

The project is required to meet the growing demands of Natural Gas in Gujarat. GSPL proposes to lay

dedicated Natural Gas transportation Pipeline from Anjar (Kutch) to Chotila (Surendranagar ) to supply

Natural Gas in most efficient manner. Pipelines are internationally recognized as the preferred alternative

for transport of fuels from the point of view of safety, economy and relative environmentally friendliness.

The pipeline will help in decongestion of roads, eventually minimizing road accidents and environmental

pollution that are generated by other means of transport.

DESCRIPTION OF THE ENVIRONMENT

AIR ENVIRONMENT

To establish the baseline status of study area, total 30 AAQ monitoring stations were selected, out of

which 21 along main pipeline route & around the SV stations along the pipeline route. In this region,

conventional air pollutants viz. PM10, Sulfur Dioxide (SO2), Oxides of Nitrogen, as well as

Hydrocarbons and Carbon Monoxide (CO), are identified for air quality assessment.

Along Pipeline route

The 24 hourly PM10 concentration varied in the range of 41-68 µg/m3 may be attributed to windblown

soil, unpaved road etc. in rural areas in the study region. The concentrations of SO2 were observed to

be varying in the range of 9-22 µg/m3. Similarly the concentration of NOx varied in the range 11-29

µg/m3 along the pipeline route.

The observed Total VOCs and Total Hydrocarbons concentration at all the locations were found non-

detectable. The observed carbon monoxide concentration at all the locations varied between 0.300-

0.489 mg/m3 which were found to be less than the NAAQS.

The total hydrocarbon concentration at all locations was observed to be non-detectable along the

pipeline route.

Around SV station

The concentration levels of PM10, SO2, NO2, CO were found to be in the range of 40-63 µg/m3, 8-27

µg/m3, 10-28 µg/m3, 0.307-0.475 µg/m3 respectively whereas Total VOCs and total hydrocarbons

were found to be non-detectable.

NOISE ENVIRONMENT

Total thirty (30) locations were identified based on the activities in the village area, traffic areas and

sensitive areas

Along Pipeline Route

Equivalent noise levels, Leq (Day) and Leq (Night) were monitored across the pipeline route. The

equivalent noise levels varied in the range of 57.8-64.8 and 35.8-40.3 dB(A) day and night time

respectively. Vehicular traffic is the major noise sources and contributes mainly to background noise

levels in the study area.

Along SV Stations:

Equivalent noise levels, Leq (Day) and Leq (Night) were monitored around the SV stations and

observed the range of 58.9-66.8 dB(A) and 35.2-40.1 dB(A) during day and night time respectively.

Noise level due to Traffic:

The national highways are passing through this region and having major traffic activities.

Agglomeration and congestion of traffic was observed on main roads and crossing of important

roads, near petrol pumps, market and Industrial areas. During survey period, traffic density at these

junctions was observed to be very high.

WATER ENVIRONMENT

The major drinking water source along the pipeline route is groundwater. Most of the villages are

having public tube wells and hand pumps for domestic use.

Physico-chemical parameters along with biological indicators of pollution have been used for

ascertaining the status of water environment along the pipeline route, and SV stations. In order to

determine the surface and groundwater quality, 2 sampling locations for surface water and 14

sampling locations for groundwater from various tube wells (TW), and bore wells (BW) covering a

total 16 sampling locations in the study area.

Water Quality Assessment

Surface Water Quality:

Surface water samples were collected from Machhu river and sea water near Haripur village. The

analysis results indicate that the pH ranged between 7.61 to 7.41 which are well within the specified

standard of 6.5 to 8.5. The TDS was observed to be 1150-37794 mg/l .The Total hardness recorded

was in the range of 310 to 1570 mg/l as CaCO3 .The nitrate was found to be in the range of 28.96 -

43.48 mg/l. The levels of chloride and sulphate were found to be in the range of 352.80-22688 mg/l

and 82-223.91 mg/l respectively. Heavy metals content (i.e. As, Al, Cd, Cr, Cu, Pb, Fe, Mn, Zn and

Hg) were found to be very low and within specified standards.

The overall surface water quality was found to be highly mineralized with respect to TDS, Hardness,

Chlorides and Sulphates. The nutrient load in terms of nitirate and phosphate was found to be high

whereas, organic load in terms of BOD and COD was found to be less indicating no organic load and

devoid of pollution. The high concentration levels of minerals might be due to creek water ingress the

source in high tide condition.

Groundwater quality

The analysis results of ground water samples indicate that the pH ranged between 7.1 to 8.35 which

are well within the specified standard of 6.5 to 8.5. The TDS was observed to be 203-1588 mg/l which

is within the permissible limit of 2000 mg/l. The Total hardness recorded was in the range of 128 to

582 mg/l as CaCO3 which is also within the permissible limit of 600 mg/l. The nitrate was found to be

in the range of 1.2-39.48 mg/l. The levels of chloride and sulphate were found to be in the range of

34.24-562.59 mg/l and 12.55-58.52 mg/l respectively. The levels of heavy metals content (i.e. As, Al,

Cd, Cr, Cu, Pb, Fe, Mn, Zn and Hg) were found to be within permissible limits.

Overall groundwater quality was found to be highly mineralized with respect to hardness, total

dissolved solids, chloride and sulphate. Nitrate concentration in some of the groundwater was found

to be high due to surface runoff carrying fertilizers used for agriculture purposes. Heavy metals were

found to be within permissible limits except Iron.

LAND ENVIRONMENT

Land use of the study area

The land use & land cover map of 196.14 km stretch including SV stations and 20 Nos. each of 10

km stretch is prepared for the land use study. The data for the proposed pipeline project was

collected using Resource SAT-2 (IRS-P6), Sensor – LISS- 4 having 5.6m special resolution and data

of pass 2nd Jan, 26th Jan and 31st Jan 2016. Land use and land cover of the study area as well as the

morphology was carried out by standard method of analysis of remotely sensed data and followed by


Executive Summary

6

ground truth and interpretation of satellite data. The outcome of the landuse study is presented in EIA

report.

Soil:

Soil was collected at different stretches along the pipeline route and around SV stations. Soil samples were

collected from 15 different locations along pipeline route and SV stations.

Physico-Chemical Characteristics

The texture of the soil was found to be silty clay, sandy clay and loamy sand in nature. Regular

cultivation practices increase the bulk density of soils thus inducing compaction. This results in

reduction in water percolation rate and penetration of root through soils. The bulk density of soils was

found to be 1.08-1.13 g/cc which indicates favorable physical condition for plant growth . The water

holding capacity of soil was in the range of 38.67-46.17%.

Chemical Characteristics

pH of soil in the study area was found to be slightly acidic to alkaline in reaction as pH was in the

range of 6.81-7.84.

The soluble salts were determined from soil extract (1:1), the soluble salts are expressed interns of

electrical conductivity (EC), the EC of the soil sample was in the range of 148.7-269.8 µS/cm. The

important cations present in soil are calcium and magnesium. It was observed that both calcium and

magnesium concentrations were in the range of 197.81-296.66 mg/kg and 80.25-180.54 mg/kg

respectively. Whereas chloride in the range of 160.51-240.48 mg/kg.

Amongst the exchangeable cations, Ca+2 and Mg+2 were found in the range of 96.44-146.47 mg/kg

and 37.11 to 86.92 mg/kg respectively along the pipeline route while sodium and potassium in the

range of 58.27-110.8 mg/lg and 74.88 – 120.7 mg/kg respectively.

Nutrient Status:

Organic matter and organic carbon present in the soil influence its physical and chemical properties

and is responsible for stability of soil aggregates. Organic matter and nitrogen were found in the

range of 2.28-2.88 % and 116.25-182.6 kg/ha. This showed that soil was moderately fertile in organic

and nutrient content.

BIOLOGICAL ENVIRONMENT

Study of biological aspects was made as per topography, land use, vegetation pattern, etc. The

biological survey was carried out by considering ecological sensitive receptors like forested area

(Protected forest and Social forest) in order to study existing status of floral composition and faunal

attributes, similarly biological survey was also carried out on non-forested area (agriculture field,

water reservoir, riverside, on hills, in plain area, village wasteland, block plantation etc. The biological

survey is mainly concerned at selected locations along the pipeline route of 500 m towards left and

right hand sides of proposed pipeline route and traversing area and 5 km periphery at stations.

Considering magnitude of impact and to know the existing status of biological environment at

immediate vicinity at station, 5 Km periphery along station was considered.

letter dated 04th September 2017. HDD method will be adopted for approx. 1.2 kms that includes

Hadakiya Creek so that there will be no disturbance to water course way, creek bed, bank & any

vegetation nearby.

Survey along the pipeline route within the wild-Ass Sanctuary Area

Flora:

The natural terrestrial vegetation of the sanctuary and surrounding area area falls under “VI – B

Northern Tropical Forest” Sub type C-I Desert Thorn Forest (Kutch, Saurashtra, Gujarat). The forest

patches falling under this category have mono-dominant Prosopis juliflora and other Acacia spp.,

Euphorbia spp., Zyziphus mauritiana was also observed in these scrubs. The ground cover generally

is of Cassia auriculiformis, Zyziphus nummularis etc.

Permanent vegetation composed of xerophytic and consists of trees and shrubs up to 6m tall or

rarely more. It is characterized by arid vegetation dominated by Acacia spp., Capparis spp., Prosopis

ceneraria, Prosopis chilensis, Calotropis procera, Cassia auriculata, Cordia gharaf, and partly


Executive Summary

Azadirechta indica. However, large open areas are extensively covered by the naturalized species

Prosopis juliflora which forms almost impenetrably thickets at the cost of natural vegetation.

Considering the species composition, the vegetation notably grouped under Type 6B/C1 – Desert as

per Champion and Seth (1968). These type of vegetation is closest to the degraded phase.

Hard wooded species like Acacia leucophloea spp. Predominate and peculiar characteristic of the

forest. The dominants vary from 4.5-10m in height and tend to be collected in clumps leaving bare

ground in between. Regeneration by root suckers is common, notably in Prosopis and Capparis.

Climbers are relatively numerous and also usually exhibit xerophytic adaptations. The woody growth

is of all sizes of Prosopis and Capparis from the trees down to the dwarf shrubs with no differentiation

in to storeys. The perennial grasses grow in clumps and tussocks. There is a thin growth of annual

grasses after the rains.

Stunted Acacia leucophloea, Acacia tortilis, A. nilotica, Prosopis cineraria are seen intermixed with

Azadirachta indica, Ziziphus spp. It is mostly invaded by Prosopis juliflora. It is a biotically controlled

community existing in a severely degraded state. Degraded scrub is the dominant vegetation type

throughout the study area. Zizyphus nummularia together with Calotropis procera are dominant

shrubs. Salvadora persica occur scattered in the scrub growth. Tribulus terrestris, Cenchrus ciliaris,

Aristida spp., Achyranthes aspera are dominant.

Fauna:

During survey indirect evidences in the form of dried pellets of wild ass were observed in notified

sanctuary area while direct sightings of wild ass seen near along Anjar – Dharngadhara Highway

near village Rapar which are almost 2.8 km away from the pipeline route. Nilgai and Jackal are very

common inhabitant in the area. The area supports variety of local as well as many migrants avifauna

species.

Salt pans

The proposed natural gas pipeline partly crosses the saltpans. Saltpans are nothing but typical tide

water impounded enclosed system adjacent to creek environment. They are characteristically

exposed to a wide range of environmental stress and perturbation which manifest mainly through

salinity changes. However, saltpans are immature ecosystem as compared with a typical marine

system and harbour a high proportion of opportunistic species. Species diversity is directly linked with

salinity. Hence the higher the salinity, the lower the species diversity and simpler the structure of the

ecosystem.

The abandoned salt pans occupy significantly large area with poor diversity. A few halophytes such

as Suaeda fruticose and Suaeda maritima were found abundant. The other herbaceous species

which grow along the bunds include Aleurops lagopoides, Aerva javanica, etc. These saltpans serve

as feeding grounds for a variety of resident as well as migrant birds.

Medicinal Plants: Wild plants of medicinal value are distributed in the area. Some of the plant

species having medicinal value like Abutilon indicum, Aerua javanica, Aerva lanata, Amaranthus

virides, Ocimum sp., Tribulus terrestris, Suaeda nudiflora, Sida acuta, etc. were quite common in

study area.

Faunal Diversity

Wildlife present on the proposed pipeline project site was identified through a combination of direct

observation and indirect indicators including vocalizations and signs (eg. scat, tracks). Wildlife survey

area out of which Limosa limosa (Black-tailed Godwit), Pelecanus philippensis (Spot-billed pelican),

Anhinga Melanogaster (Darter), Mycteria leucocephala (Painted Stork) observed in study area are

Near Threatened (NT) Category as per IUCN.

Agriculture

Agriculture and Horticulture crops along pipeline route

During survey, various types of agriculture and horticulture crops were observed along the pipeline

route. Areas near the coastal zone having a good water potential and good soil cover are used for

raising horticultural crops like date palm, coconut, pomegranate, mango, chiku (sapota), guava etc.

The other horticulture crops includes, Psidium guava (Jamfal), Carica Papaya (Papaya), Moringa

oleifera (Drumstick), Citrus aurantifolia (Nimbudo) etc. Agriculture crops dominated with Ricinus

communis (Castor), Triticum aestivum (Gehu), Herbaceum gossypium (Cotton), Cicer arietinum

power supply and medical facility etc. Economic attributes and the infrastructure resource details

have been abstracted from housing, house hold amenities and assets. Cultural and aesthetic

attributes falling under the study area as tourist attraction in the study area are detailed in the report.

Awareness and Opinion of People about the Pipeline Project

Pipeline will cross Agriculture Farm, National highway, State highway as well as barren land and

forest area. Most of the people in study area were unaware about pipeline project, however those

who were directly involved because of their farm or barren land coming under pipeline project were

aware about project. People opinion was positive about project because they felt that pipeline project

will generate employment and expected from the project authorities.

Quality of Life

The average QoL index value for the study area is leading to satisfactory level due to satisfactory

economic status like, good educational facilities, communication facilities, fair transportation facilities

and also availability of basic needs viz., food, clothing & housing. Moreover, since proposed project is

for laying a natural gas pipeline and creating the supply and demand network which will help to bring

more industrial activities and economic growth of the region, the quality of life of the people in the

region will automatically increase in a positive way.

ANTICIPATED ENVIRONMENTAL IMPACT AND MITIGATION MEASURES

AIR ENVIRONMENT

Construction Phase

Construction of the Anjar – Chotila Pipeline involves civil, electrical and mechanical work involving

different types of machinery and is labor intensive. Environmental impacts related to construction

works are mostly temporary in nature and last only during the period of construction.

The study area is relatively clean and does not have any major source of air pollution as shown by

the baseline status on air quality.

Impact

Various construction activities contribute to marginal air pollution in the area such as:

Dust generation from transportation of construction material by Road, grading, activities, civil

works and movement of vehicle.

PM, CO, NOx & SOx generation due to operation of DG set.

Mitigation Measure

Ensuring preventive maintenance of vehicles and equipment.

Water sprinkling.

Ensuring vehicles with valid Pollution under Control certificates are used.

Ensuring stacks height of DG set as per SPCB norm for adequate dispersion.

Operation Phase


Executive Summary

11

A DG set will be kept as standby mode and will be operated as secondary means only when the

primary supply from GEB is not available, at SV/IP/DT/RT station.

Impact

PM, CO, NOx & SOx generation due to operation of DG set

Mitigation Measure

Operation Phase

Impact

Noise generation due to operation of DG set.

Mitigation Measure

Providing DG set with acoustic enclosure / exhausts mufflers.

WATER ENVIRONMENT

Construction Phase

Minimum water will be used during construction phase of pipeline. Water requirement during

construction period (at peak) is approximately estimated as 50-60 KLD.

Impact

Water generated from hydro test.

Domestic waste water.

Mitigation Measure


Executive Summary

12

Maximization of the reuse of hydrotest water to the other section of pipeline.

Major crossing job will be carried out during dry season

Ensuring supply of portable toilet for construction staff.

Preparation of sock pit & septic tank.

Operation Phase

There will be no requirement of water for the pipeline operation along the route. However, marginal

water will be required for domestic use at the SV stations during operational phase. The total water

requirement during operational phase is estimated approx. 20 KLD.

Impact

Domestic waste water.

Mitigation Measure

Preparation of sock pit & septic tank for disposal of sewage.

Installation of rainwater harvesting structures at Stations.

LAND ENVIRONMENT

Construction Phase

Impact

A very marginal quantity of earth excavated for terminals and pipeline lying will become

surplus after installation of the pipeline and may be required for disposal. However, the

aesthetics of the pipeline RoU and soil quality will not be affected.

The pipeline route Anjar-Chotila passes through agriculture land at most of the places. Some

part of the pipeline route passes through the sandy soils with minimal vegetation.

Major land use along the proposed pipeline route is agriculture / barren land thus there will be

very less impact on land-use pattern along the pipeline route. No change in land use pattern

along the pipeline route is envisaged as the land will be restored to its near original condition

and hand over to land owner after laying the pipeline.

Land will be permanently acquired for all stations (surface facilities).

Mitigation Measure

In the adjoining areas soil type is silty, sandy, Loamy, clay followed by sandy loam with

medium percolation. However, every precaution will be taken to avoid spillage on soils during

construction phase to protect groundwater quality and soil microbiology in pipeline route and

SV stations

Construction activities may be carried out within the ROU of pipeline.

Excavated top soil will be segregated and restored back to near to original state after

completion of pipeline laying.


Executive Summary

13

A record with respect to quantity, quality and treatment / management of solid/ hazardous

waste shall be maintained.

Disposing hazardous wastes to authorized vendors as per legal provisions.

Any kind of materials resulting from clearing and grading will not be deposited on temporary or

permanent basis in the approach roads, streams, ditches and any other position which may

hinder the passage and / or natural water drainage.

On completion of construction works, all temporary structures, surplus materials and wastes

will be completely removed from the site to avoid future land use incompatibility. During of

construction, waste on agricultural land will be prohibited.

The pipeline corridor for laying the buried pipeline will be about 20m wide and the total

estimated corridor length is about 196.14 km. This will be obtained on a right of use (RoU)

basis. The land will be restored to near original condition after the pipeline is laid, hence

impact on land use pattern due to laying of pipeline will be marginal and reversible

Standard construction procedures will be implemented to ensure that the impact on surface

drainage pattern and soil erosion is kept minimal. This will necessarily include avoiding

blockage of natural surface drainage and developing appropriate drainage system in areas

where it is unavoidable.

The current topography and land usages of the project area will not be adversely affected due

to limited constructional activities for the project.

Operation Phase

The land on permanent basis is required at SV stations only. The land requirement at each

associated facilities such as Sectionalized valve Stations /Tap-off/Metering /Receiving/

Dispatch/Intermediate Pigging stations is approximately 0.36 Ha. Thus the total area requirement for

11 associated facilities (SV/IP/RT/DT) is 3.96 Ha approximately..

Impact

There is a potential for impact on soil quality due to spills during pigging of pipelines, handling

storage or hazardous waste (used oil) & chemical, if any.

Mitigation Measures

Proper collection, transportation and temporary storage of pigging wastes.

Adequate reuse of used oil.

BIOLOGICAL ENVIRONMENT

Construction Phase:

Impact of on-land Flora & Fauna

Construction will involve a range of disturbing activities including excavation, civil works,

drilling, pipe-laying, welding and testing. Nuisance - related impacts will include dust, noise

and vibration.


Executive Summary

14

These impacts may be local on species for a short period but none of these effects are likely

to result in more than a temporarily, making nuisance to sensitive species (wild ass and

nesting bird species) close to the proposed pipeline route.

Clearance of vegetation for ROU and site preparation.

Road kills of animal due to vehicle movement.

Trapping of animals in pipeline trench / un-barricaded pits

Cutting of trees for firewood by construction workers

The other possible impacts during the construction phase like bush fires, road and open trench,

hunting and prosecution, etc. was also studied and mitigation measures provided accordingly.

Mitigation Measures:

Closing of trenches as soon as possible after pipeline laying works.

Hard barricading of trench when the pit is opened for long duration..

Avoid tree cutting, wherever possible.

Prohibiting use of firewood in project camps and making use of cooking gas mandatory.

Prevent littering of work sites with wastes, especially plastic and hazardous waste.

Awareness among the drivers in order to regulate speeding and avoid road-kills.

Company has a policy for road safety which sets speed limits for vehicles operating for the

company.

Conservation plan recommended for Schedule – I Flora and Fauna.

Compensatory Afforestation needs to carry out in association with forest department as per

Forest guidelines & Act.

Impact on aquatic flora and fauna

The primary concern is the crossings of pipeline through the two waterways: Hadkiya Creek

and Salt Pan thus, biological resources could be affected in Hadkiya Creek.

Crossing of Hadkiya Creek or maintenance activities in it could create sedimentation or

erosion

A pipeline accident (spill or leak) resulting in products flowing into the creek could result in

death or injury to species living or feeding in downstream areas.

Mitigation Measures:

Construction within Hadkiya Creek shall be guided by the following restrictions:

NO CONSTRUCTION in Hadkiya Creek may occur during rainy season.

The construction schedule shall call for construction on Hadkiya Creek to be completed as

quickly as possible

Excavation within the creek bed shall be limited to the pipeline right-of-way, except as

otherwise approved by appropriate permitting agencies


Executive Summary

15

No labour camp in this CRZ area.

Use of equipment and mainline construction activities within rivers shall be limited to

minimum.

The mud and drilling fluids generated during the drilling operations shall be disposed-off in an

approved manner.

Operation Phase

Impact Evaluation

The movement of operation related vehicles may result in road kills of animals.

Cutting of vegetation on ROU during pipeline maintenance.

Mitigation Measures

Avoiding tree cutting wherever possible.

Regulating speeding of project-related vehicles.

Public awareness programme

The local people will be educated to understand the importance of wildlife conservation and

plantation program and be encouraged to take active part in agro forestry and social forestry program

with the leading role played by the GSPL and Forest Department.

SOCIO-ECONOMIC ENVIRONMENT

Positive Impacts

Amongst the most common positive effects that household will be general growth in

commercial and industrial activity in the area.

Proposed project is expected to contribute improvement of quality of life in the region

The civil amenities like medical facilities, market, education, sports and cultural activities will

likely to improve in the study area.

Increase in infrastructure resources due to the project by way of transport and communication

and other basic requirements will be generated for the working population of the project.

There will be some visible positive benefits along the pipeline route. Wherever feasible, local

labor will be used as much as possible during construction for land clearing, land stabilization,

restoration of top soil, and restoration of local roads. This would create employment

generation of locals & also help in improving of the existing socio-economic status.

Negative Impacts

Discontent among landowners due to delayed payment of compensation .

Change in the local socio economic environment due to the increased activities


Executive Summary

16

Degradation of the environment, and damage to local roads and other infrastructure during

construction

Mitigation Measures

Ensuring timely payment of Land/Crop compensation to the landowners as per GW&GP Act

2000.

Vocational training programmes will be organized for the local people. That may developed

there capacity as skill and will be helpful for them in getting more employment opportunities.

An emergency preparedness plan will be prepared in advance, to deal with firefighting,

evacuation and local communication.

A road safety awareness campaign will be carried out to better inform the communities about

road safety. Journey management will be followed.

Consolidating deliveries of materials and personnel to project sites, whenever feasible, to

minimize flow of traffic

ANALYSIS OF ALTERNATIVES

Technology Alternatives

Pipeline laying and transportation of natural gas in an established practice worldwide. Latest

Technology and construction machinery will be used for pipeline construction so that minimum

damage will done to the surroundings. Gas pipeline network will be monitored continuously using

SCADA system.

Alternatives for Project site

The proposed evacuation pipeline route would not pass through any environmentally sensitive aeras,

(except wild ass sanctuary, Hadkiya creek and salt pan crossing), human habitations, archeological

monuments. The major land use along the proposed pipeline is agricultural, national and state

highways. There are no established breeding grounds and migratory routes along the pipeline route.

During Reconnaissance, Route Verification and Validation, a number of development, obstacles,

forest land, villages (dwellings), were noticed which needed to be avoided. Therefore new pipeline

route was aligned keeping in view the about mentioned aspects.

Environment Monitoring Programme

The proposed Anjar-Chotila pipeline runs underground at minimum depth of 1-1.2 m and is controlled

by SCADA system which allow continuous monitoring and rapid closure of valves, therefore there are

very rare chances of leakage and therefore regular monitoring of eleven SV stations will be done to

assess the surrounding environmental quality.

PROJECT BENEFIT

The pipeline, during construction and operation phase will generate direct and in-direct

employment as there will be requirement of unskilled and skilled workers in site activities,


Executive Summary

17

supply of raw material, auxiliary and ancillary works, which would improve the economic

status of the people in area.

Proposed Natural gas pipeline developmental project will result in considerable growth of

service sector and will also generate new industrial and business opportunities in the areas

through which it will pass Small and medium scale industries may also be developed as a

consequence.

The proposed Natural gas pipeline will also lead to investment by major industries in Gujarat.

Investment by big industrial players will generate employment for the local population.

Due to easy availability of Natural gas, emissions from the same industrial setups will also be

reduced to a large extent.

Transportation by pipeline is comparatively less expensive than the other modes of transport,

both in the capital and operating costs. If a good network of pipelines is implemented

throughout the country, this will ensure that the pipeline-transported products will be available

to the consumers at a lower cost than alternate modes of transport

Pipeline will be able to feed natural gas to multiple industrial units and thereby helping them in

switching over to cleaner fossil fuel.

Connectivity to city gas network to pipeline from delivery point will reduce the requirement of

LPG cylinders used in households.

Pipelines are internationally recognized as the preferred alternative for transport of

hydrocarbons from the point of view of safety, economy, reliability, and relative

environmentally friendliness.

ENVIRONMENTAL COST BENEFIT ANALYSIS

As a consequence of rapid industrialization in India, fuel needs are increasing at a rapid rate and

supply demand gap is widening. Pipelines are internationally recognized as preferred alternative for

transport of fuels from the point of view of safety, economy and relative environmentally friendliness.

The cost of this project is estimated to be 1058.40 crore including contingency cost to take care of

any inflation and exigencies. These cost estimates are primarily based on cost of piping material,

equipment and facilities, RoU and pipeine laying cost incurred by GSPL for its recently implemented

pipelines and market enquiries on latest prices.

Besides the tangible benefits, the project has got number of intangible benefits like minimum

emissions of the green house gases, no adverse impact on environment, socio-economic benefits to

the local people and the region and enhancement of the fuel/energy for the country. The

establishment of Anjar-Chotila Pipeline, when operated will provide significant supply of fuel to the

consumers.

Health, Safety and Environmental Management System

The objective is to identify any significant HSE risks, particular to this project which cannot be

adequately managed by the normal risk management processes and construction HSE

procedures. Following the one-off overall construction HSE risk assessment, a systematic

assessment of all health, safety and environmental risk shall be carried out during the

planning of all construction activities which will include the following:

1.0 INTRODUCTION

1.1. PROJECT PROPONENT

As a fuel, natural gas competes with a range of alternative products such as coal and lignite as well

as petroleum products such as liquefied petroleum gas, naphtha, high speed diesel, light diesel oil

and fuel oil. However, due to lower fuel operating costs and better combustion characteristics, natural

gas has distinct economic advantages over other sources of energy. In addition, natural gas has

substantial environmental advantages over other energy sources, due to lower emissions.

The development of proposed project is for natural gas transportation within state of Gujarat. The

proposed project is planned to be developed by M/s Gujarat State Petronet Limited (GSPL).

M/s GSPL, a Government of Gujarat undertaking is one of the leading company in the field of Natural

Gas transmission line. It is in the process of expanding its pipeline network all over the Gujarat State

to take care of future demand-supply gap to fulfill the requirements of various consumers throughout

Gujarat. It is first company in India to transport natural gas on open access basis and is a Pure

Natural Gas Transmission Company.

GSPL is a pioneer in developing energy transportation infrastructure and connecting natural gas

supply basins and LNG terminals to growing markets. It is continuously expanding its pipeline

network in Gujarat to reach the demand centers by laying gas pipeline network. The company has

developed requisite expertise and confidence with proven project management competencies.

GSPL is the second largest Natural Gas transportation company in India and presently operating

pipeline network in the state of Gujarat.

1.2. PROJECT BRIEF

In order to facilitate the augmentation of gas supply to various consumers in Gujarat, an analysis of

the infrastructure requirements has been carried out and based on such analysis, it was decided to

create suitable infrastructure facilities like LNG import terminal and creation of network of high-

pressure gas transmission pipelines to facilitate transportation of gas from point of supply to points of

demand related to the consumers/industries (domestic, petrochemicals, power plants and other allied

industries) which will help to increase the economic output of the region and thereby the nation.

Moreover, being a green gas, it is environment friendly and the cost of transportation will be

drastically reduced as compared to other means of transportation and supply to the consumers will

be in cheaper rate.

The project is required as existing pipeline from Varsamedi (Anjar to Chotila) will not meet the total

transportation volume requirement from the GSPC LNG Terminal. GSPL would be the only company

to have pipelines in this section for transportation of natural gas for which M/s Gujarat State Petronet

Limited (GSPL) has received the Authorization from PNGRB (Petroleum and Natural Gas Regulatory

Board) for the development of following project for the transportation of Natural Gas with a

permissible RoU width along the pipeline route (Annexure I).

GSPL proposes to lay a network of Gas Pipeline for the supply of Natural Gas to various consumers

situated at Gujarat state. There are numbers of supporting industries that have been developed in

Anjar, Gandhidham, Kandla & Bhuj region of Kutch district. In order to fulfill the requirement of natural

gas in future, GSPL proposes to lay a pipeline for the supply of Natural Gas from Anjar to Chotila.

The proposed Anjar to Chotila Pipeline will originate from village Ratanpar-(GSPL's ARPL SV-8 TOP-

8), Taluka-Sayla of district-Surendranagar, pipeline stretch will cover a distance of 196.14 km,

thatruns through Surendranagar, Morbi & Kutch regions and terminates at GSPL's Dispatch station at

village Rata Talav, Taluk Anjar & district-Kutch of Gujarat..

The Index map is shown in Figure 1.1 and pipeline route is shown in Figures 1.2. The panoramiv

features of Anjar-Chotila pipeline route is also shown in Figure 1.3, as well as the key locations

through which the pipeline is passing and the SV stations along the route are presented in Plates 1.1.

The proposed facilities along the pipeline route of Anjar to Chotila underground Natural Gas Pipeline

Network with associated facilities such as SV/Tap-off/Metering /Receiving/ Dispatch / Intermediate

Pigging/Sectionalized valve Stations. The Proposed alignment also meets the other broader requirements

of laying criteria of the pipelines. Accordingly, the present pipeline route has been selected for the

transmission of natural gas to various parts of Gujarat. The proposed pipeline alignment runs through

2.0 PROJECT DESCRIPTION

2.1 TYPE OF PROJECT AND CAPACITY

The proposed project is planned to be developed by M/s Gujarat State Petronet Ltd. (GSPL). This

project aims at establishing pipeline network covering the states of Gujarat to take care of future

demand-supply gap of natural gas. GSPL proposes to lay Anjar-Chotila gas Pipeline approx. 196.14

km network of gas pipeline for the supply of natural gas to fulfill the requirements of various

consumers.

There will be 11 surface facilities (SV/IP/RT/DT) along the pipeline route at designated locations for

the proper maintenance of the pressure and flow of natural gas and accordingly distribution. The flow

of the gas through pipeline will be approx. 23.13 MMSCMD. The proposed pipeline will help to create

network in the region for supply to the consumers which will help to increase the economic growth of

the region.

2.2 JUSTIFICATION & NEED OF PROJECT

The project is required to meet the growing demands of Natural Gas in Gujarat. Thus GSPL proposes

to lay dedicated Natural Gas transportation Pipeline from Anjar (Kutch) to Chotila (Surendranagar ) to

supply Natural Gas in most efficient manner. Pipelines are internationally recognized as the preferred

alternative for transport of fuels from the point of view of safety, economy and relative

environmentally friendliness. The pipeline will help in decongestion of roads, eventually minimizing

road accidents and environmental pollution that are generated by other means of transport.

As India has witnessed rapid urban and industrial growth in the past two decades, and with the

country’s current liberalization policy this growth is expected to accelerate and need additional energy

for development. As a consequence of the rapid rate of industrialization in India, fuel needs are

increasing at an equally rapid rate and the supply-demand gap is widening and steps must be taken

to address this issue. Overload transport of fuels by trucks is uneconomical, unsafe, and is a

contributor to environmental degradation in terms of the fuel consumed and pollutants released by

vehicles in transit and by accidents and spillages (common on Indian roads).

Pipelines are internationally recognized as the preferred alternative for transport of fuels from the

point of view of safety, economy and relative environmentally friendliness. The qualities of

underground pipelines that make them desirable from these angles are that they are buried

underground (at minimum depth of 1-1.2 m) and are controlled by SCADA systems.

The road and rail transportation systems, at present, have to share the load of transporting raw

materials and finished products from the supply centers to the demand / consumer centers. Rail

transport is utilized for carrying bulk of the petroleum products throughout the country and the

balance quantity is transported by road. This is stretching the transport sector capacity and hiring the

movement of other essential raw materials and products.

Transportation of gas by underground pipeline is comparatively less expensive than the other modes

of transport both in the capital and operating costs. If a good network of pipelines is implemented

throughout the country, this will ensure that the pipeline transported products will be available to the

consumers at a lower cost than alternate modes of transport.

Gujarat State Petronet Ltd. (GSPL) proposed Chotila-Anjar Pipeline will originate from village

Ratanpar (GSPL's ARPL SV-8 TOP- 8) Taluka; Salaya & District; Surendranagar, Gujarat and

pipeline stretch will cover a distance of 196.14 km, that runs through Surendranagar, Morbi & Kutch

regions and terminates at GSPL's Dispatch station at village RataTalav, Taluk Anjar & District Kutch

of Gujarat State.

Alternative routes are examined and the present route as stated above is finalized based on least

disturbance to the environment, human habitations, forest, aquatic bodies. The route is optimized

considering the above factors and connectivity between supply and demand points. However, the

proposed pipeline is passing through Gujarat state avoiding forest areas or in any event, it is passing

through forest areas, separate forest clearance or permission will be obtained as per Forest

(Conservation) Act 1980 and subsequent amendment thereof.

2.4. PROCESS DETAILS AND INFRASTRUCTURAL FACILITIES

The production and manufacturing is not involved, as the project is for transportation of natural gas.

(Plate 2.2).

2.4.1. TRANSPORTATION PROCESS OF NATURAL GAS

PLATE 2.2 PROCESS FLOW DIAGRAMS

2.4.2. Phase of Project

2.4.1.1 Construction Phase For Pipeline Laying:

The pipeline construction is proposed to be carried out through deployment of 2 to 3 spreads. The

sequence and methodology of construction of new pipeline is given below:

1. Clearing and Grading - A 20 m wide Right of Use (RoU) area will be cleared off vegetation

and other obstacles such as boulders.

2. Stringing - Pipes are transported to the site on trucks will be offloaded using side booms.

Pipes are then strung adjacent to the trench. Trailers and cranes will be used for maneuvering

of pipes. This activity may be done before or after trenching.

3. Trenching - Trenchers and backhoe type excavators will be used to dig the trench for laying

the pipeline. The topsoil in agricultural areas will be removed and stockpiled for restoration.

The excavated sub-soil will be stockpiled separately for backfill.

4. Bending - Pipes will be bent using a bending machine to the appropriate angle to match the

vertical and horizontal alignment of the trench.

5. Welding - Welding will be done using conventional manual/ semi-automatic welding involving

a crew of welders and fitters.

2-13

6. Non-Destructive Inspection - Mechanized Ultrasonic Testing (MUT) is the specified method

to be applied for the execution of NDT. Each field weld will be 100% radiographed to test for

soundness of the weld in compliance with specifications. NDT and its evaluation shall be

performed in accordance with API Standard 1104.

7. Coating - After welding at each weld joint, coating of field joints of bare pipes and the repair of

coating shall be done

8. Lowering - Padding will be provided, wherever required, in the bottom of trench to prevent

damage to the coating.

9. Burial - General burial depth of the pipeline along the route will be with a minimum 1.0 m

cover. Burial cover will be compacted to avoid future erosion by all weathers.

10. Backfilling - The excavated sub-soil will be returned to the trench. The topsoil, which has

been preserved on the side of the ROU, will be spread over the filled up trench. A crown of

soil will be kept on top of the trenched portion to allow for future settlement. Backfilling will be

managed so that damage from sizable rocks is not used or any other materials that may

damage the pipeline.

11. Crossings - The method used for the crossing of waterways and other infrastructure facilities

will vary from place to place depending on the environmental setting and the geo-technical

features of the area.

For the critical river/canal crossings Horizontal Directional Drilling (HDD) will be adopted and

at other places open cut method shall be used based on topography of the crossing by taking

necessary statutory permission

12. Restoration - Restoration of the ROU will be conducted progressively following the

completion of construction work. This will involve removal of foreign materials such as

construction debris and wastes. The ROU will be returned to its original condition by

spreading the topsoil over the areas from where it was stripped, so that agricultural activities

will be restored. Special focus will be given to restoration of side slopes and beds of natural

water body crossings.

13. Pipeline warning markers–In the final stages of construction, warning marker posts will be

erected indicating the location of the pipeline and the crossing of other pipelines, cables and

features. A marker tape will be placed in the trench 500 mm above the pipeline to indicate to

future excavators that a pipeline is below and that they are nearing.

2.4.1.2 Construction Phase For associated facilities

At SV station sites, the construction will be undertaken within the station. The other steps of

construction shall be more or less same as the pipeline given below:

Clearing of the identified location

Modification of the boundary wall wherever required.

Leveling and approach road laying

Foundation works

Construction water supply

Structural works

Mechanical erection



2-14

2.4.1.3 Operation Phase For Pipeline

The activities involved in the operational phase of the project are as follows:

1. Commissioning of the pipeline: Prior to commissioning of the pipeline, a number of pre-

commissioning operations like cleaning and hydrostatic testing of pipeline, starting of

mechanical and rotating equipments will be carried out. After successful pre-commissioning

activities, the pipeline shall be commissioned for transfer of Natural Gas.

2. Utilities: The water requirement in the stations during the operational phase will be met by

bore wells or outsourced through road tankers.

3. Normal operation: During the normal operation of pipeline, the activities will be mainly

confined to the battery limits of terminals.

4. Infrastructure facilities: Infrastructure facilities to support the anticipated worker population

and the project like municipal facilities, firefighting facilities, sewerage maintenance, power

supply, water supply and maintenance etc, will be provided where ever required.

5. Post construction protection system: The entire pipeline will be protected against external

corrosion by a cathodic protection system. Pipe external coating will be done at the coating

plant before it is transported to site.

6. Inspection of pipeline: Regular inspection of the pipeline shall be carried out as per standard

practices. A SCADA monitoring and control system will be utilized ensuring effective and

reliable control, management and supervision of the pipeline network system. In addition to

SCADA, physical patrolling along the pipeline route will also be carried out by line walkers

daily.

2.4.1.4 Operation Phase For Associated Facilities:

Once the pipeline is commissioned, there will be a regular visit by the operation engineers as per

drawn up schedule to ensure safe operations. Inspection work will be undertaken on a routine basis.

Inspection pigs will be propelled in the pipeline once in two years to check the health and dimension

of the pipeline.

2.4.3. CONSTRUCTION MATERIAL

Carbon steel pipelines of 36’’diameter will be laid for a total length of 196.14 km. Pipe material and

pipe type are API 5L Gr. X-70 PSL-2 and LSAW/HSAW respectively. It will be commissioned as per

PNGRB guidelines. For SV stations construction materials such as MS, sand/ soil, cement, diesel oil

etc. will be procured from local sources.

GSPL will follow the codes and regulations to meet National and International standards.

2.4.4. RESOURCE OPTIMIZATION / RECYCLING AND REUSE ENVISAGED IN THE PROJECT

Resource Optimization / recycling and reuse envisaged in the Project

All the construction and testing equipment used in the project will be put to use in other

similar project once the project is completed.

Water used for hydrostatic testing of pipes during commissioning will be stored and used for

other pipes.



2-15

Rain water harvesting and recycled water will be used for sanitary purposes, green belt

development and gardening purposes as practicable.

2.4.5. WATER SOURCE & CONSUMPTION

The source water requirement for pipeline construction is minimum, which will be met through Road

tankers from available sources in the nearby area. However, during operation phase water will be

sourced from bore or dug well inside the SV Stations for domestic purpose and tree plantation

depending upon the requirements.

2.4.5.1. WATER CONSUMPTION

Water consumption will be Max. 50-60 KL/day during Construction period, and during operations it

will be approx. 20 KL/day.

2.4.5.2. WASTEWATER GENERATION

During construction phase the liquid wastes generated from the construction camp will be discharged

through soak pit/septic tank. Similarly the domestic waste generated from the SV stations will also be

sent to septic tank/ soak pit. During construction, the marginal liquid effluent or spoiled / drained

lubricants oil generated at construction camp will be disposed off as per SPCB guidelines.

No waste water on continuous basis from pipeline operations is envisaged. During operation phase

domestic waste water will be generated at Stations and that will be disposed to the septic tank/ soak

pit. The waste water generated during the hydrostatic testing of euipment & pipeline is temporary &

one time activity. The same water will be reused for multiple tests in other sections. The residual

hydrotesting waste water at the end of test will be non-toxic & disposed off suitably.

2.4.6. ELECTRICITY (POWER REQUIREMENT)

Required power for SV / IP / Dispatch / Receiving shall be drawn from nearest local power source of

the state Electricity Boards. Approx. 11 Nos. of DG sets with each have capacity of 50 KVA will be

provided. However, DG sets will be kept as standby at Stations.

2.4.7. SOLID AND HAZARDOUS WASTES

Solid Waste: Marginal amount of solid watse will be generated at the camp site along the pipeline

route, and same will be disposed as per SPCB/CPCB guidelines. Quantity of wastes generated is

expected to be 0.2-0.5 kg/per capita/day during construction activities (plastics, waste papers and

card board, etc). Solid wastes generated will be properly collected, segregated and reused / disposed

off appropriately. On completion of construction works, all temporary structures, surplus materials and

wastes will be completely removed and land will be reinstated to near its original state. Dumping of

construction waste on agricultural land will be prohibited. Only excavation soil will be generated

during construction, which will be reinstated to near original condition after laying the pipeline.

Hazardous waste: generated at the time of construction will be used oil, chemical & lube oil barrel,

batteries, welding electrodes etc and will be disposed as to SPCB authorized recycler/dealer/TSDF

sites.



2-16

Hazardous wastes generated during operational activities in the form of spent oil from DG sets,

equipments & pigging waste etc., will be reused as lubricant and drums will be disposed off as per

SPCB/CPCB guidelines.

The detailed estimation of solid waste generation during construction and operation phase is as

follows:

SOLID WASTE GENERATION (Kg/day)

Sr. No. PARTICULARS Workers/Manpower SOLID WASTE GENERATION (Kg/day)

B Operation Phase 06 0.5 X 06 = 03 Kg/day

C SV STATION (11 Nos.)

Construction Phase 10 x 11 = 110

(5 Skilled, 3

Unskilled and 2

security)

110 x 0.5 = 55 Kg/day

D Operation Phase 2 x 11 = 22 22 x 0.5 =11 Kg/day

A. Along the pipeline route:

The domestic solid waste generation during construction phase will be 50 Kg/day and during

operation phase it will be 3 Kg/day so the total domestic waste generation 53 Kg/day along pipeline

route

B. In SV station:

The domestic solid waste generation during construction phase will be 55 kg/day and during

operation phase it will be 11 kg/day so the total domestic waste generation will be 66 kg/day.

2.4.8. TRANSPORTATION

It is intended to make maximum use of the existing infrastructure and augment/ strengthen existing

roads, wherever required. Hence no major changes are envisaged due to this buried natural gas

pipeline project.
