1.5 POWER REQUIREMENT

The estimated power requirement during operation is about 6140 KVA

and it will be sourced from the nearby TNEB grid. DG set of 3 x 2000 KVA &



1 x 1500 KVA capacity will be provided to cater essential load requirement

during power failure.

The stack height for the DG sets are calculated based on the CPCB

guidelines as shown below;

Stack Height Design Calculation for 2000 KVA

H = h + (0.2) (kVA) 0.5

= 51.88 + 0.2 (2000) 0.5

= 51.88 + 8.9

= 60.8 ~ 61 m.

Where, H = Total height of stack in meters from ground level

h = Height of the building in meters

The stack height required as per CPCB norms is 61 m for 3 D.G Sets of

capacity 2000 KVA.


H = h + (0.2) (kVA) 0.5

= 51.88 + 0.2 (1500) 0.5

= 51.88 + 7.7

= 59.6 ~ 60 m.



The stack height required as per CPCB norms is 60 m for D.G sets of

capacity 1500 KVA.



1.6 BASELINE ENVIRONMENTAL STATUS

Baseline studies are carried out to provide a detailed description of the

existing ecosystem, landscape, infrastructure, cultural heritage and urban

environment. A baseline study describes the initial state of the environment

within the selected boundaries of the study area. The baseline data has been

generated and the secondary data was collected from various Government and

Semi-Government organizations. The details about the existing environmental

values are projected based on the volume of the assessment accomplished

during the period. The various environmental attributes were divided into

primary and secondary studies. Primary attributes such as air environment,

water, soil, noise & biodiversity environment were being assessed by

conducting field studies, on-site monitoring. The baseline studies started with

site visits and survey in the study area for fixing the monitoring locations for

the primary data generation. The baseline environmental data for ambient Air,

Noise, Soil and Ground water is enclosed in Annexure XI. The brief on the

study of bio-diversity is summarized below.

1.6.1 Biodiversity Study

a. Methodology

The ecological status of the study area has been assessed based on the following

methodology:

Primary field surveys to establish primary baseline of the study area

Compilation of information available in published literatures and as

obtained from Forest survey of India, Botanical Survey of India and

Zoological Survey of India.

The flora and fauna studies were carried out within 1 km radius around the

proposed construction site.



b. Flora

The Study of flora involved intensive sample survey of vegetation in the project

site and other locations applying standard methods. To examine the trees and

shrubs, quadrants of 25 x 25 m and for herbs 2 x 2 m were laid. In each of the

larger quadrants (i) Species (ii) their number, and (iii) Girth at Breast Height

(GBH), were measured. (Chaturvedi and Khanna, 1982).

Abundance, relative abundance, density and relative density of each species

diversity and evenness for each of the Zones were calculated using the numerical

data (Ludwig and Reynolds 1988, Lande 1996, Smith and Wilson 1996). The

standard statistical analysis, the normal frequency diagram and distribution of

plants in the study area were analyzed using the procedures of Raunkiaer, 1934.

The analysis carried out as per Raunkiaer’s law of frequency classes provides the

information on the Heterogeneity and Homogeneity of plants and its pattern of

distribution in the study area. The species of vegetation found in each station were

identified and listed according to their families, both in dicotyledons and

monocotyledons of the plant kingdom. The plant species were classified as per the

classifications of “Bentham and Hooker” and identified by using Gambles book on

“Flora of Madras Presidency” and Mathew’s book on “Flora of the Tamil Nadu

Carnatic”.

c. Fauna

Both direct and indirect observation methods were used to survey the fauna.

Visual encounter (search) method was employed to record vertebrate species.

Additionally survey of relevant literature was also done to consolidate the list of

vertebrate fauna distributed in the area (Smith 1933-43, Ali and Ripley 1983,

Daniel 1983, Prater 1993, Murthy and Chandrasekhar 1988). Since birds may be

considered as indicators for monitoring and understanding human impacts on



ecological systems (Lawton 1996) attempt was made to gather quantitative data on

the group by.

Point Survey Method: Observations were made in each site for 15 minutes

duration.

Road Side Counts: The observer traveled by motor vehicles from site to site,

all sightings were recorded (this was done both in the day and night time). An

index of abundance of each species was also established.

Pellet and Track Counts: All possible animal tracks and pellets were

identified and recorded (South Wood, 1978).

Based on the Wildlife Protection Act, 1972 (WPA 1972, Anonymous.

1991, Upadhyay 1995, Chaturvedi and Chaturvedi 1996) species were short-listed

as Schedule II or I and considered herein as endangered species. Species listed in

Ghosh (1994) are considered as Indian Red List species.

Pellet and Track counts method was adopted for this development project

and the assessment results are discussed in Chapter-3.

1.7 ENVIRONMENTAL COMPONENTS

The baseline environmental studies helped in assessing the existing

environmental conditions of the study area and identifying the critical

environmental attributes. This will facilitate the comparison of the resultant

environmental conditions in the post study scenario with the pre- study

conditions and will help in checking the environmental pollution.

1.8 WATER REQUIREMENT

The total water requirement during operation is 438 KLD. Source of water

is CMWSSB. The wastewater generation from the project is estimated to be

about 299 KLD, which will be treated in proposed sewage treatment plant of

320 KLD capacity and will be recycled for flushing, gardening and remaining



excess treated sewage will be disposed to CMWSSSB sewer line and the water

balance chart is shown in Table 6, 7 and 8.

occupants) in separate bins. Door to door waste collection system will be

adopted. Compostable waste will be treated in organic waste convertor within

the site. Manure generated will be used within the site for landscaping purpose.

Recyclable fraction of waste will be sold to authorized vendors and inert waste

will be send for land filling through authorized agency for waste collection in

the area. Organic waste convertor of various makes like Excel, Nachiket

Engineering, Earth Care equipments are available. These OWC reduce volume

of waste fed by 80% and convert it into manure that can be used for

landscaping purpose. This manure can be stored, packed, sold and used for

landscaping.

Apart from the municipal waste, E-waste comprising of rejected CFL,

bulbs, laptops, TV sets, computers etc will be generated. This waste will be

insignificant in initial stage. Room will be provided within project site for

storing discarded electronics. This will be sold to authorized vendors on regular

basis.



CHAPTER – 2

2.0 ENVIRONMENTAL IMPACT ASSESSEMNT

2.1 INTRODUCTION

This chapter presents the assessment of various impacts due to the

proposed construction project in the study area. Generally, the environmental

impacts can be categorized as either primary or secondary. Primary impacts

are those, which are attributed directly by the project and secondary impacts are

those, which are indirectly induced and typically include the changed patterns

of social and economic activities by the proposed project. The Proposed

construction project would create impact on the environment in two distinct

phases:

Impacts during the construction phase

Impacts during the operation phase

The construction and operational phase of the proposed construction

project comprises of various activities each of which will have impact on some

or other environmental parameters. Various impacts during the construction or

operational phase and the environmental parameters have been studied to

estimate the impacts on environment. The identification and details on impact

of the project activity on each of the above environmental attributes are

discussed below.

2.2 IDENTIFICATION OF IMPACTS

Construction of commercial complex is for the benefit of general

population, however, like any other projects, it also has impacts on existing

Environmental settings and if not properly evaluated and controlled, it may lead



to imbalances. These impacts could be reversible, irreversible, temporary or

permanent.

The identification of impacts is important as it leads to the other elements

such as quantification and evaluation of impacts. Although a number of non-

projects related impacts have been identified while describing the existing

(baseline) environmental status, it is necessary at this stage to identify the types

of the potential impacts which might be caused by the proposed development.

Many techniques are available for identification of impacts. In case of this

project, the "Matrix Method" was adopted, which involves an understanding of

the cause-condition-effect relationship between an activity and environmental

parameters. It is very useful as gross screening tool for impact identification

method. This method has been basically advantageous in recognizing the series

of impacts that could follow from the proposed activities.

The idea was to account for the project activity and identify the types of

impacts that could initially occur. This process was repeated until all possible

types of impacts were identified. With this method the potential impact of the

proposed project has been identified.

2.3 IMPACT EVALUATION

Impact evaluation assesses the expected changes in the environment due

to the proposed project. It is the tool for identifying the magnitude of impact

and forms basis for the development of Environmental Management Plan.

Weight age for each impact is given below. Evaluation of impacts considering

both positive and negative effects on air, noise, land, water and socioeconomic

environment during the construction and operation phase of the project is given

in Table 11 and 12 respectively.

2.4 IMPACT ON AIR ENVIRONMENT

2.4.1 Construction Phase

Impacts of construction activities on air quality are cause for concern

mainly in the dry months due to dust particles. The main sources of emission

during the construction period are the movement of equipment at site and dust

emitted during the leveling, grading, earthworks, and other construction related

activities. The dust emitted during the above mentioned activities depend upon

the type of soil being excavated. Existing baseline parameters values are SOx-

9.4 µg/m3, NOx- 19.4 µg/m

3 and SPM- 49.6 µg/m

3. An average of 20-30 %

incremental pollution during construction for air parameters will be envisaged.

However, the impact will be for short duration and confined locally to the

construction site. The composition of dust in this kind of operation is, however,

mostly inorganic and non-toxic in nature.

The impact of such activities would be temporary and restricted to the

construction phase. The impact will be confined within the project boundary

and is expected to be negligible outside the plant boundaries. Proper upkeep

and maintenance of vehicles, sprinkling of water on roads and construction site

are some of the measures that would greatly reduce the impacts during the

construction phase. Thus, it is inferred that no significant impacts are expected

on the overall ambient air quality due to the proposed construction activities.

Transportation of heavy machinery and building materials implies heavy

traffic on the roads leading to the site with possible negative impacts to the

surrounding area (dust, spillage, emissions and noise). Transportation of

construction materials as well as improper storage of building materials,

especially gravel, sand and cement in the construction site will lead to

inadvertent dispersal of materials during heavy rain or high wind during dry



periods. Measures will be adopted for proper handling of construction

materials to reduce the negative impact.

2.4.2 Operation Phase

Ambient air quality at the proposed project site and its surroundings is

monitored and values of the pollutants RPM, PM2.5, NOx and SO2 are within the

limits of NAAQS, 2009 prescribed by the central pollution control board.

There is no major pollutant envisaged from the proposed development. It

is likely that the air quality may be affected slightly due to the emissions from

the vehicular movement. The emission from DG sets will be very negligible

since it will be used only during power cut in the necessary area. However in

the case of DG sets the stack will be properly designed to meet the stipulations

of CPCB. These emissions will be insignificant and the environmental pollutant

levels will be maintained within the prescribed limits. Hence there shall not be

any adverse impact on the air environment around the proposed commercial

complex.

2.5 IMPACT ON AMBIENT NOISE


During the construction noise levels will increase due to use of machinery

and heavy vehicles in the project area. In terms of noise emission; demolition,

excavation and construction work can be divided into two phases, namely (1)

Demolition and Earthworks and (2) building works. Loading and unloading of

construction materials, fabrication, handling of equipment and material,

operation of power shovels etc. will be the major source of noise during the

construction phase. Various construction activities will cause short-term noise

impact in the immediate vicinity of the project site.



The areas affected are those close to the site and hence the impacts are

localized. At the peak of the construction, marginal increase in noise levels is

expected to occur. The peak noise levels from continuous construction activity

may be as high as 80 - 90 dB (A). The noise control measures during

construction phase shall restrict the noise levels to lower levels. Hence the

overall impact on the ambient noise levels will not be significant.


There will not be any major impact from noise. This is because no

equipment or other infrastructure facility in the project generates noise more

than 50-60 dB (A). However, the only noise generation source is the DG set.

The promoters have decided to adopt adequate steps to maintain the noise

levels within the prescribed limits. For the same all the DG facility will be

equipped with acoustic enclosure. Apart from this honking will be prohibited at

the site and speed limits will be restricted within the site. This will significantly

help in controlling noise levels at the site. Further the green belt provided

within the site will act as noise barrier between inside and outside environment.

This will act as buffer and protects the site from high noise levels outside the

site.

Traffic will increase during both construction and operation phase of the

project. Vehicles associated with construction would generate intermittent

noise throughout the vicinity of the proposed action. In the operation phase,

vehicular parking is being provided in the basement, ground floor and first

floor of the building where noise levels are expected to increase substantially

during the peak hours due to starting, idling and roaring of vehicles.



2.6 IMPACT ON LAND ENVIRONMENT

No blasting will be done during construction phase of the project. The

rehabilitation and resettlement issues are not involved in the project.

Furthermore the existing environmental conditions of the project site reveal that

the land is not contaminated or polluted.

Top soil will be excavated up to 15 cm from the project site. It will be

stored in covered area during construction phase and will be used for

landscaping in operation phase within project site. The upper/top level of soil

will be affected during construction phase but this will be limited to a portion

of the project area. Also the impact due to exploitation of ground water is

insignificant in the site due to the sourcing of water from other sources during

the operation phases.

2.7 IMPACT ON WATER RESOURCES


The required water quantity for construction will be utilized from the

available resource in the project area. Impact on water quality during

construction phase may be due to non-point discharges of sewage generated

from the construction work force, stationed at the site. Construction activities

for the proposed development can have minor impact on hydrology

and ground water quality of the area if the construction waste leaches into

ground.

Potential sources of impacts on the hydrology and ground water quality

during the construction phase would be soil runoff, improper disposal of

construction debris, spillage of oil and grease from the vehicles and wastewater

stream generated from on-site activities such as vehicles washing, workshop

etc. Precautions and preventive measure will be taken at the site during



construction to avoid any ground and surface water contamination hence the

overall impact on water environment during construction phase due to proposed

project is likely to be insignificant.


The total quantity of wastewater generation is likely to be 299 KLD which

will be treated in proposed sewage treatment plant of 320 KLD capacities and

will be recycled for flushing, gardening, OSR and remaining excess treated

sewage will be disposed to CMWSSB.

2.8 IMPACTS DUE TO WASTE DISPOSAL

2.8.1 Stacking and Disposal of Construction Materials

Stacking of construction materials will be confined to the project site only

and also temporary sheds will be provided to store the materials, hence no

impacts on surrounding area will be envisaged. Solid wastes generated due to

proposed project during construction phase include sand, gravel, stone, bricks,

plastic, paper, wood, metal and glass. Recyclables will be sent to authorize

recyclers. Hence there is no significant impact due to waste disposal during the

construction phase.


The solid waste generated from the project will be collected daily and

moved to a common temporary storage facility by the staff dedicated for waste

collection. The collected Solid waste will be disposed through Organic waste

converter.



2.9 IMPACTS ON ECOLOGICAL RESOURCES


The impact of construction activities will be primarily confined to the

project site. The project site is a vacant land and devoid of any vegetation. Thus

the site development work will not lead to any significant loss of any important

plant species. Deposition of fugitive dust on leaves of nearby vegetation may

lead to temporary reduction of photosynthesis. Such impacts will, however, be

confined mostly to the initial period of construction phase. Hence the proposed

development will not lead to habitat destruction, fragmentation or vegetation

damage.


No wastewater will be discharge into the surface water stream. Hence,

there will not be any impact on the aquatic ecology. Also the proposed project

is to be located in an earmarked commercial zone, which does not have any

natural park or sanctuary or forest area in the immediate vicinity. The flora and

fauna pattern in the area will not be disturbed due to the project. Hence the

overall impact on ecological resources due to proposed project is likely to be

insignificant. Moreover the entire project area would be landscaped with

variety of plants.

2.10 IMPACT ON TRAFFIC LEVELS


The movement of construction equipments will be mostly within the site

during the project. Vehicles bringing in raw materials like sand, cement and

aggregate materials will be moving into the site from outside, which will be

strictly controlled and monitored as per the traffic rules, to avoid any sort of

disturbance to the traffic and safety of the surrounding areas. Hence the impact



due to the vehicular movement during the construction phase would be minor

or insignificant.


Based on the vehicular density observed during the traffic survey

conducted on the main roads around the proposed site, the existing

infrastructure is capable of taking up additional traffic loads. Also the project is

to be executed phase wise; the increase in traffic will be easily handled by the

existing as well as the future improvements in the transportation infrastructure.

Hence there will not be any impact on the traffic pattern and density.

2.11 IMPACTS ON SOCIO ECONOMIC ENVIRONMENT

The required land for the development is owned by M/s. Anandram

Developers Pvt Ltd. The proposed Mall/ Hotel/ Theatre complex will be open

to members of all communities and castes. The above measure will encourage

mixing of different caste people for their respective festivals and occasions.

This will improve the social welfare and brotherhood among the various

communities and castes.

Also the state of the art facilities proposed in the development is planned

to cater the needs of the occupants which would be able to provide healthy

working atmosphere. Hence it is obvious to assume that the activities of the

proposed development will produce some positive impacts in the socio-

economic status of the area.

2.11.1 Public Health and Safety

As the project is only a construction of Mall/ Hotel/ Theatre complex and

all the construction activities are confined to the project site, no health related

impact would be envisaged within the project area. The people engaged in the



construction activities will be directly exposed to dust generation, which is

likely to cause health related impact. Appropriate mitigation measures like

spraying of water will be adopted to minimize dust emission in the construction

site. Laborers will be provided with suitable Personal Protective Equipment

(PPE) as required under the health and safety norms. Regular health checkups

will be organized.

2.11.2 Positive Impact

The project will facilitate maximum participation of the local work force

for construction process; this will benefit the local economy, improvement in

economic activity and enhancement in earning opportunities for the local

population. The operation of the project and other allied facilities will improve

the employment opportunities. The project will provide direct and indirect

employment. About 100 – 150 persons will be employed during the operation

stage for the purpose of day-to-day maintenance works. The employment will

have positive impact on the local economy thereby increasing the quality of

life. The proposed rain water recharge facility will augment the ground water

level in the project area. The proposed project will also improve the aesthetics

of the area due to the development of modern buildings.



CHAPTER - 3

3.0 ENVIRONMENTAL MANAGEMENT PLAN

3.1 GENERAL

Environmental Management Plan (EMP) is aimed at mitigating the

possible adverse impacts of the project and for ensuring to maintain the

environmental quality. The environmental management plan consists of the set

of mitigation, management, monitoring and institutional measures to be taken to

eliminate the adverse environmental impacts or reduce them to acceptable

levels.

3.2 AIR POLLUTION CONTROL AND MANAGEMENT


The impacts will be due to the air emissions like particulate matter (PM10&

PM2.5), CO, NOx and SO2 due to material handling, vehicular movements and

other site activities. The particulate matters will be reduced by frequent

sprinkling water on the road surfaces and on other areas where dust is arising

due to material handling. All the equipments and vehicles used in the

construction and transportation of materials will be maintained properly and

only low sulphur diesel will be used as fuel for DG sets and construction

equipment and vehicles.

The emissions from the DG sets will be let out only through the stacks

with adequate heights as per CPCB norms. This will avoid the deposition of the

particulate matters and other pollutants by facilitating the through dispersion of

pollutants into the atmosphere. The stacking of all the construction materials

will be confined only within the proposed site. Vehicles carrying the raw

material and debris will be covered to minimize dust emissions while travelling.



Adequate parking space will be provided for construction vehicle and

machinery to prevent idling and thus will help in minimizing the emissions.

Wheel wash facility will be provided at the exit point of the site.


Air emissions are observed during the operation phase of the project. The

air emissions will be reduced by ensuring smoother flow of traffic within the

premises by better traffic management plans. It is proposed to have trees all

through the boundaries of the site and along the either side of the internal roads.

This will reduce the particulate matters from being transported to the nearby

areas. The air emissions from the Diesel Generators will be controlled by using

low sulphur content high speed diesels, periodic maintenance of DG sets as per

the defined schedule of manufacturer and by providing adequate stack heights

as prescribed by CPCB. The stack height for the DG sets are calculated based

on the CPCB guidelines as shown below;

The proposed project to have

4 nos. - D.G. Sets of 3 x 2000 KVA Capacity and 1 x 1500 KVA

3.2.3 Air Pollution Control (APC) Measures

The main source of air emissions from the proposed commercial

development is the Generator Sets the above proposed generator sets will be

used only during TNEB power failure. To control the air emissions from these

D.G sets, adequate stack height is provided to release the exhaust flue gases into

the atmosphere at a height at which efficient dispersion takes place. Since the

DG sets are operated only during power failure, the emission is not continuous

and hence the impact due to these emissions is insignificant.



The stack height for the DG sets are calculated based on the CPCB

guidelines as shown below;

Stack Height Design Calculation for 2000 KVA Generator Set

H = h + (0.2) (kVA) 0.5

= 51.88 + 0.2 (2000) 0.5

= 51.88 + 8.94

= 60.82 ~ 61 m


h = height of the building in meters

The stack height required as per CPCB norms is 61 m which will be provided

for all 3nos. of 2000 KVA DG sets.


H = h + (0.2) (kVA) 0.5

= 51.88 + 0.2 (1500) 0.5

= 51.88 + 7.7

= 59.6 ~ 60 m.



The stack height required as per CPCB norms is 60 m for D.G set of capacity

1500 KVA.



3.3 NOISE CONTROL AND MANAGEMENT


The noise generated from the construction equipments will be reduced

through proper maintenance of all the equipments which are involved in

construction activities, confining the construction activities only during the day

time and providing barricades all around the project area. The adverse impacts

of noise especially on workers will be reduced by providing ear muffs to the

workers in high noise zones. Noise control systems such as equipment

foundation pads, dampeners, silencers and acoustic enclosures will be used for

individual units as per the requirement to minimize the noise & vibration.


The increase in the ambient noise levels due to the vehicle transportation

will be controlled by the development of the green cover all along the internal

roads and by implementing better traffic management plans inside the site

premises. The better traffic management plans will significantly reduce the

noise generated due to the congestion caused by the movement of vehicles.

The generator noise is controlled by providing acoustic enclosures. Proper

air ventilation system is designed to allow the maximum aspiration and cooling

airflow required so that the engines do not overheat. Axial flow fan of required

size & numbers provided for proper air ventilation. Acoustic louvers, splitter &

insulated ducts are provided to suppress the noise where required.

Also Noise monitoring was done during the study period. The values were

Leq Day: 52.7 dB (A) Leq Night: 36.5 dB (A). The values were within the

limit. Also during operation care will be taken to ensure that there will not be

any incremental load in the environment.



3.4 SOLID WASTE MANAGEMENT


Separate raw material handling yard will be demarcated. This will prevent

the contamination of the soil due to the spillage of the construction materials.

Cement will be separately stored under cover in bales. The raw material

handling yard will be located within the project site and separated by

enclosures/barricades. This will keep the working area clean and reduce the soil

contamination.


During the operation phase the used oil from the DG sets will be collected

in separate drums and handed over to the authorized recyclers by TNPCB.

Hazardous Waste: During the operation phase the used oil, DG filters, oil

mixed cotton waste and oil containers from the DG sets will be collected in

separate place.

Non- Hazardous Waste:

It is estimated that the municipal solid wastes will be generated in the

following passion:

Biodegradable wastes : 6579 Kg/day

Non-biodegradable wastes : 1816 Kg/day



In the commercial complex development, Wastes generated from the

households will be segregated into Bio degradable waste and non- bio

degradable waste in the source itself (by the occupants) in separate bins. The

wastes from such bins are collected separately on daily basis and taken to a

separate centralized collection facility by the agency dealing in collection and

disposal of garbage. Appropriate site will be identified for keeping the

biodegradable and Non-biodegradable waste. All the collection bins shall be

properly maintained and cleared on regular basis. The Bio degradable wastes &

inert fractions will be disposed off through the local municipality, and non-bio

degradable recyclable waste will be handed over to authorized recyclers.

Horticulture wastes leaves, grass and vegetative residues shall be collected

at the secured location such that it will not hinder daily activity schedule or

washed away by the surface run-off causing choking of drains, etc. and will be

separately treated and disposed off along with biodegradable waste.STP sludge

will be stabilized, and dewatered for separation of solids, which will be used as

manure in horticulture.

It is proposed to use the recycled water for the part of the daily water

demand in the premises. The total water requirement during operation is

438KLD and the fresh water requirement is 160 KLD. The source of water is

taken to be CMWSSB since the quality of borewell water from the baseline

study was found to be TDS 668 mg/L; Total hardness 303 mg/L; sulphates 71.4

mg/L and chlorides 143 mg/L does not comply with drinking water

specification as per IS 10500:2012. Hence it is not recommended for drinking

purpose, and it is also not advisable for other domestic uses due to very high

salt content. In case of emergency, Water Treatment Plant will be proposed for

domestic uses, for which the quality of treated water will be TDS < 500 mg/L;

Total hardness < 300 mg/L; chlorides < 250 mg/L and sulphates < 200 mg/L.

The components of water treatment plant will be aeration tank, settling tank,

sand filter and carbon filter with iron removal media filled in it. The wastewater

generation from the project is estimated to be about 299 KLD, which will be

treated in proposed Sewage Treatment Plant of 320 KLD capacity. Treated

sewage will be reused for flushing, gardening, OSR and the remaining excess

sewage will be disposed through CMWSSB sewer lines. The sewage treatment

design is described in the Annexure - VII.

3.6 STORM WATER MANAGEMENT


The surface runoff during the construction period will be directed into the

drains separately provided for this purpose.




Rain water from internal roads etc will be discharged through storm water drain

sloping towards rain water collection sumps. The Rainwater down comer pipes

from terrace level directly connected to rainwater inspection chambers

interlinked and discharged to filtration bed to store Rain water of min. An

overflow pumping main pipe will be laid as lead pipe from rainwater harvesting

trench up to the road for draining the excess water during rainy seasons.

DESIGN PARAMETERS:

Total Plot Area Considered 18149.26 Sqm

Total roads and pavement area 3557.79 Sqm

Total Greenbelt Area 2915.43 Sqm

Co – efficient of runoff considered for roof area : 0. 90

Co – efficient of runoff considered for road/paved area : 0. 75

Co – efficient of runoff considered for landscape area : 0. 1

Hence, the total quantity of rainfall will be: q= a x p x r

q = quantity of rainwater run - off in cu.m / hr.

a = area of catchments drained in Sq.m

The runoff from rooftop will be diverted to the rain water collection

trench.

During abnormal rains, the excess runoff after storage and recharge will

be disposed off through the external storm water drains.

a. Details of recharge pit

Recharge through Pits : 69 nos.

A portion of rain water falling over the roofs, road and paved area and the

open area will be used for recharging the ground water. The dimension of pits is

1500 mm diameter and 1500 mm depth. Recharge pits are normally excavated

as any shape, which are sufficiently deep to penetrate the low-permeability

layers overlying the permeable layer. They are similar to recharge basins in

principle, with the only difference being that they are deeper and have restricted

bottom area. In many such structures, the infiltration occurs vertically through

the permeable layer is much higher than the low permeable layer occurring in

the top.



The pits will be filled with gravels (1-10mm) at bottom, coarse sand (1.1-

2mm) at middle and fine sand at the top in graded form. Gravels at the bottom,

coarse sand in between and fine sand at the top so that the silt content that will

come with runoff will be deposited on the top of the fine sand layer and can be

easily be removed. The top sand layer of the recharge pits will be periodically

cleaned to ensure the proper recharge.

Fig. 4 Cross section of recharge pit



b. Recharge Trenches

Recharge trenches are normally excavated as linear pits, which are

sufficiently deep to penetrate the low-permeability layers overlying the

permeable layer. They are similar to recharge basins in principle, with the only

difference being that they are deeper and have restricted bottom area. In many

such structures, the infiltration occurs vertically through the permeable layer is

much higher than the low permeable layer occurring in the top. Recharge

Trench will be constructed in the premises of the company across the slopes.

Trench maintained all along the boundary, the depth of the trenches will be

around 1.5 m. It is planned to remove the entire impervious layer to facilitate

rain water recharge. The width of the proposed trenches is 1 m. Pebbles of

different size will be provided in an ascending order in the tank and a layer of

sand will be provided on top of the filter media. The rain water flowing through

the open land, paved area and green belt area will be used for recharging to

ground water through the above said trenches.

c. Rain Water Storage Sump:

Rain water storage sump 1,60,000 litres capacity- 1 nos. is proposed for

rainwater storage and reuse.

The Rain water storage and harvesting plan has been designed as per the

Rain water harvesting (RWH) & conservation manual by CPWD, Govt .of

India, 2002 & in compliance with Ministry Notification dated 9th December

2016 under 50,000 to 1,50,000 Sqm category.

d. Flood Occurrence:

The highest recorded monthly rainfall in that area and surroundings of

Chennai is 521mm in 2010, considering the previous 5 years day peak rainfall



(Refer Table below from IMD). The storm water management has been done,

the total peak flow at the site by taking 600 mm of highest average rainfall/day

in site, the runoff will be 498.2 cubic meter/hr after development, the recharge

pit, storm water collection sump and storm water collection drain have been

designed in the site to the manage the rain water during heavy rainfall time.

3.13 DISASTER MANAGEMENT PLAN

A disaster or emergency is a threatening condition that requires urgent

action. Effective emergency action can avoid the escalation of an event into a

disaster. Emergency management involves plans and institutional arrangements

to engage and guide the efforts of government, non-government, voluntary and

private agencies in comprehensive and coordinated ways to respond to the

entire spectrum of emergency needs.

The overall objective of an Emergency Response Plan (ERP) is to make use

of the combined resources at the site and outside services to achieve the

following:

1. To localize the emergency and if possible eliminate it;

2. To minimize the effects of the accident on people and property;

3. Make the rescue and medical treatment of casualties more effective;

4. Safeguard other people;

5. Evacuate people to safe areas;

6. Informing and collaborating with statutory authorities;

7. Initially contain and ultimately bring the incident under control;

8. Preserve relevant records and equipment for the subsequent enquiry into

the cause and circumstances of the emergency;

9. Investigating and taking steps to prevent reoccurrence.



The ERP is therefore related to identification of sources from which hazards

can arise and the maximum credible loss scenario that can take place in the

concerned area. The plan takes into account the maximum credible loss

scenario - actions that can successfully mitigate the effects of losses/ emergency

need to be well planned so that they would require less effort and resources to

control and terminate emergencies, should the same occur.

Main hazards identified for the project include hazards pertaining to fires in

buildings and fire in diesel storage areas, earthquake and LPG leakage and an

ERP pertaining to these is described in the following section.

3.13.1 Response in case of earthquake

a. Earthquake Preparedness

1. Know how and where to take cover during a quake

2. Anchor furniture over 42”. Do not stack furniture

3. Move tall bookcases away from exits. Do not use them as room dividers

4. Anchor computers, equipment, and display cases

5. Store heavy items at floor level

6. Back up critical data. Keep duplicates off-site

b. Response Procedures for Occupants

If indoors:

1. Take cover under a piece of heavy furniture or against an inside wall and

hold on.

2. Stay inside: The most dangerous thing to do during the shaking of an

earthquake is to try to leave the building because objects can fall on you.

If outdoors:

Move into the open, away from buildings, streetlights, and utility wires. Once in

the open, stay there until the shaking stops.

If in a moving vehicle:



Stop quickly and stay in the vehicle. Move to a clear area away from buildings,

trees, overpasses, or utility wires. Once the shaking has stopped, proceed with

caution. Avoid bridges or ramps that might have been damaged by the quake.

1. After the earthquake be prepared for aftershocks.

2. Although smaller than the main shock, aftershocks cause additional

damage and may bring weakened structures down.

3. Aftershocks can occur in the first hours, days, weeks, or even months

after the quake.

4. Help injured or trapped persons.

5. Give first aid where appropriate. Do not move seriously injured persons

unless they are in immediate danger of further injury. Call for help.

6. Remember to help those who may require special assistance--infants, the

elderly, and people with disabilities.

7. Stay out of damaged buildings.

8. Use the telephone only for emergency calls.

c. Response Procedure for Emergency Team

1. Formulate an Emergency Response Team for earthquake response.

2. Using the public address system, inform people of response procedures

discussed above.

3. Inform the necessary authorities for aid.

4. Ensure no person is stuck beneath any debris, in case of a structural

failure.

5. Ensure that all occupants standing outside near the buildings are taken to

open areas.

6. Ensure that the first aid ambulance and fire tender vehicles are summoned

if necessary.

7. Inform the nearby hospitals if there are any injuries.

8. Check the utilities and storage tanks for any damage.



3.13.2 Response in case of fire

a. Fire Preparedness

1. Note the location of alarms and extinguishers. Know how to use them

2. Leave fire doors closed at all times

3. Clear obstructed corridors, aisles and room exits

4. Limit use of extension cords and multiple outlets

5. Do not use mechanical rooms or utility rooms for storage

b. Response Procedures for Occupants

1. Required response during in the event of a fire should be described in

signs located in the lobby.

2. On sighting a fire, it should be immediately informed to the environment

manager giving the exact location and type of fire in detail.

3. Initiate the Emergency Response Team for fires.

4. If the fire is small, engage in extinguishing the fire using the nearest fire

extinguisher.

5. Guide the Emergency Response Team staff to the emergency assembly

point.

6. The Emergency Response Team should immediately inform the nearest

dispensary and security force. If required a fire tender should be

summoned.

7. The response team should immediately move to the point of fire and take

all necessary steps to stop the fire. If the fire is not controllable and

spreads then the manager in charge should inform the district authorities

and call for external help.

8. The Emergency Response Team will provide immediate relief to the

injured at the scene of incident. Any injured persons should be evacuated

on priority to the dispensary or one of the nearest hospitals based on their

condition.



c. Instructions for occupants

1. Get out of buildings as quickly and as safely as possible.

2. Use the stairs to escape. When evacuating, stay low to the ground.

3. If possible, cover mouth with a cloth to avoid inhaling smoke and

gases.

4. Close doors in each room after escaping to delay the spread of the fire.

5. If in a room with a closed door.

6. If smoke is pouring in around the bottom of the door or if it feels hot,

keep the door closed.

7. Open a window to escape or for fresh air while awaiting rescue.

8. If there is no smoke at the bottom or top and the door is not hot, then

open the door slowly.

9. If there is too much smoke or fire in the hall, slam the door shut.

10. Stay out of damaged buildings.

11. Check that all wiring and utilities are safe.

A state of the art fire fighting system is proposed for the project to

prevent and control fire outbreaks. The fire fighting system will consist of

portable fire extinguishers, hose reel, wet riser, yard hydrant, automatic

sprinkler system, and manual fire alarm system. The buildings will also be

provided with automatic fire detection and alarm system.

3.14 Environment Monitoring Plan

Environmental monitoring plan is a vital process of any management plan

of the development project. This helps in signaling the potential problems that

resulting from the proposed project and will allow for prompt implementation

of effective corrective measures. The environmental monitoring will be

required for the construction and operational phases. The main objectives of

environmental monitoring area:
