Environment Management Plan Report

Dankuni is a fast-growing industrial township near Kolkata, India. The town is part of the

Hooghly District, in the State of West Bengal. It is a part of the area covered by Kolkata

Metropolitan Development Authority. It is well-reachable by road or trains from both Howrah

Station and Sealdah Station. Dankuni Junction rail station is 15 km from Howrah Station.

Nearest Airport is Dum Dum, situated 20 Km from Dankuni.

Both NH 2 and NH 6 terminate at Dankuni. The PalsitDankuni section of NH 2 is also

referred to as Durgapur Expressway. Other major arteries meeting at Dankuni are Belghoria

Expressway connecting to NH 34 and the DankuniMemari Delhi Road. Dankuni railway

station is located on the Howrah-Bardhaman chord, which was constructed in 1917. The

Calcutta Chord from Dum Dum to Dankuni over the Willingdon Bridge (renamed Vivekananda

Bridge) was opened in 1932.It is part of the Kolkata Suburban Railway system. Already, there

is a growing presence of freight and wagon movements around Dankuni Railway Station,

which is important as it connects Eastern Railway with South Eastern Railway with a link line.

Dankuni has a fast growing freight yard, where goods traffic is moved, sorted, and packed to

deliver at other destinations. In the future, Dankuni will play a significant role because it will

be the endpoint of the Ludhiana-Dankuni leg of the Dedicated Freight Corridor that is beingbuilt by Indian Railways. Traffic, especially that of freight will continue to grow and will

positively impact the railways.

The breakdown structure of this project i.e.Setting up of electric locomotives factory at

Dankunias a whole is as under,

We are at the execution stage where the main role is to monitor and control the Environmental

aspects, beside other engineering input, based on previous reports / established documents and

Government Policies / rules for the said project.

Construction process is invariably involving disturbance of the existing physical environment

in the vicinity it is undergoing. During this process, residues in the form of wastes will be

formed. If the residues are not properly disposed off / recycled/ re-utilized they become waste

and have to be discharged into environment as pollutants. The degree to which the pollutants

affect the physical environment depends upon their quantitative and qualitative characteristics

as well as that of the receiving media. However, as a general rule any Construction/

development process is accompanied by some environmental problems. Proper planning at the


4/35

conceptual stages can minimize many of these problems. Once the physical environment is

affected badly it becomes difficult and expensive to retrofit pollution control equipment, as

such incorporation of the same at conceptual stage itself is the best alternative. We presume that

at the conceptual stage this has been properly addressed and covered so that later on when this

production unit will come into force no eventuality so far as environmental issues areconcerned is faced. However as it is beyond our scope of the work so we are not required to

study / comment on the same.

So far as construction phase of the project is concerned a number of acts, rules and ambient

standards exist under the Government of India (GOI) which will help to ensure that the program

will be implemented in an environmentally safe and friendly manner. Key policies that this

project is subjected to comply with are:

The Environment (Protection) Act, 1986; The Environmental Impact Assessment Notification, 2006 and its amendment in 2009; Environmental Impact Assessment Guidelines for Rail, Road and Highways Projects,

1989;

Forest Conservation Act 1980 (Amended 1988) and Rules (1981 Amended 2003); Wildlife Protection) Act, 1972 (Amended 1993); Water Prevention and Control of Pollution Act 1972 (Amended 1988) and its Rules 1974; Air Prevention and Control of Pollution Act, 1981, (Amended 1987) and its Rules 1982; Noise Pollution (Regulation and Control) Rules, 2000 (Amended 2002); Hazardous Waste Management, Handling and Trans boundary Movement Rules 2008

(Amended 2009), and Batteries Management and Handling Rules 2001.

These Acts and Regulations envisage that:

i. No environmental clearance is required for railway projects. However, periodic review

will be made of amendments if any in this notification, for the applicability and need of

environmental clearance for railways project.

ii. Forest clearance from Department of Forests is required for diversion of forest land for

non-forest purpose. Prior permission is required from forests department to carry out anywork within the forest areas and felling of rail side trees. Cutting of trees need to be

compensated by compensatory afforestation as per the requirement of forest department.

Not applicable in the present case.

iii. Placement of hot-mix plants, quarrying and crushers, batch mixing plants, discharge of

sewage from construction camps requires No Objection Certificate (Consent to Establish

& Consent to Operate) from State Pollution Control Board prior to establishment.


5/35

iv. Permission from Central Ground Water Authority is required for extracting ground water

for construction purposes, from areas declared as critical or semi critical from ground

water potential prospective by them.

The Executing Agency (EA) for the program is the Ministry of Railways (MOR) and the

Implementing Agency (IA) is the Railway Vikas Nigam Limited (RVNL) under theGovernment of India.

DEFINITION OF EIA / EMP & EMS

Environmental Impact Assessment (EIA) is a study to identify, predict, evaluate and

communicate information about the impacts on the environment of a proposed project and to

detail the mitigating measures prior to project approval and implementation

Environmental Impact Assessment (EIA) is a planning tool generally accepted as an

integral component of sound decision-making. EIA is to give the environment its due place in

the decision-making process by clearly evaluating the environmental consequences of the

proposed activity before action is taken. Early identification and characterization of critical

environmental impacts allow the public and the government to form a view about the

environmental acceptability of a proposed developmental project and what conditions should

apply to mitigate or reduce those risks and impacts.

EIA is analysis of issues and recommendations EIA is documented in an Environmental

Assessment Report (EA Report)

ENVIRONMENTAL ASSESSMENT (EA)

Objective

To identify or obtain information on any relevant environmental impact that the

construction project may cause.

Suggested measures

Identify sensitive environmental areas or uses that may be affected by construction

activities.

Identify whether residents adjacent to the site could be affected by pollution from

construction activities or suffer reduced amenity.

Monitor baseline air and water quality and ambient noise levels adjacent to the

construction site.

Conduct an assessment of expected noise levels from construction activities which

may affect the surrounding community.

Conduct a desk study to identify potentially contaminated sites in the construction

area, and sample and analyse soils that are suspected of being contaminated before

construction commences.


6/35

The EIA mechanism shall be applied to the project in the following order of priority:

Avoid adverse environmental impact Minimize and control adverse environmental impact Mitigate adverse environmental impact

The implementation of measures designed to reduce the undesirable effects of a proposed

action on the environment is called Mitigation.

Different types of Mitigation measures act in different ways to reduce adverse impacts:

Type of measure How it works Examples

Prevention &

Control measures

Fully or partially prevent an

impact/reduce a risk by:

Changing means or technique Changing the site Specifying operating practices

PREVENT contamination of wells,

by SITING wells a minimum

distance from latrines.OPERATE wastewater treatment

system for a coffee-washing station.

Compensatory

measures

Offset adverse impacts in one area

with improvements elsewhere

Plant trees in a new location to

COMPENSATE for clearing a

construction site.

Remediation

measures

Repair or restore the environment

after damage is done.

Re-grade and replant a borrow pit

after construction is finished

Environmental Management Plan (EMP) is a site-specific plan developed to ensure that all

necessary measures are identified and implemented in order to protect the environment and

comply with environmental legislation. EMP is an action plan based on results of EIA

ENVIRONMENTAL MANAGEMENT PLAN

Objective

To develop an environmental management plan to reduce the adverse impact of

construction activities on the environment.Suggested measures

A environmental management system should be in place, as a pre-requisite to

preparing an environmental management plan.

Prepare an environmental control plan for defined segments of the site for large sites,

or a whole-of-site plan for smaller sites.


7/35

The plan should implement the risk management action plan, include detailed

specifications on site-specific controls and include a rehabilitation program in the

plan.

Base the measures in the plan on best practice. Update the plan to meet new risks or where inspections, monitoring or audit reveal

that measures are ineffective.

Update the plan to achieve ongoing improvement

Environmental monitoring is a necessary complement to mitigation. It should be a normal

part of monitoring project results.

Environmental monitoring is,

Systematic measurement of key environmental indicators over time, within a

particular geographic area

Systematic evaluation of the implementation of mitigation measures

Mitigation & Monitoring are a critical part of environmentally sound design:

Mitigation minimizes adverse environmental impacts & Monitoring confirms that mitigation

measures are sufficient & effective.

Mitigation and monitoring for an activity is defined by the Mitigation and Monitoring (or

M&M) Plan (also called an Environmental Management Plan, or EMP)

The EIA reports which must have been prepared along with Project Conception to

Sanctioning stage were not available nor do any comments on the same comes under the

preview of this Consultancy so they are not commented at this stage.

However in general in my view no significant or adverse environmental impacts are

anticipated during construction stage and what so ever minimum effect will arise will be

temporary in nature.

The environmental impacts related with the project are manageable, however monitoring the

EMP implementation and environmental conditions needs to be done systematically to ensure

mitigation of any unexpected environmental impacts.

No significant impacts are anticipated on biodiversity or physical cultural resources becausethe land used was already in railway use. Impacts are primarily from construction activities

and transportation of construction material. It has been made mandatory for the contractor to

adopt safe construction practices and ensure use of requisite personnel protective equipment

to protect occupational health of labour and communities around the construction sites.

The costs for environment related issues are included under the contractors construction

costs & Cost for monitoring the EMP is included in the PMC contract.


8/35

The implementation agency (IA) i.e. RVNL is to help Construction agency who is fully

responsible to ensure to obtain necessary consents or permissions (e.g. environmental

clearance, forest clearance, and water board clearance) from relevant Government Agencies.

RVNL is also to ensure that all necessary regulatory clearances are obtained prior to

commencing any civil work of the project. It will also to be ensured that the EMP whichinclude required mitigation measures and monitoring requirements are properly followed by

the contract-ting agency. This is also to be ensured that construction workers work under safe

and healthy working environment.

For the effective and consistent functioning of the project, an Environmental Management

System (EMS) is to be established at the site. The EMS should include the following:

i. An Environmental management cell

ii. Environmental Monitoring

iii. Personnel Trainingiv. Regular Environmental Audits and Corrective Action

v. Documentation Standard operating procedures Environmental Management Plans

and other records

Apart from having an Environmental Management Plan (EMP), it is also necessary to have a

permanent organizational set up charged with the task of ensuring its effective implementation of

mitigation measures and to conduct environmental monitoring. The major duties and

responsibilities of Environmental Management Cell shall be as given below:

i. To implement the environmental management plan,

ii. To assure regulatory compliance with all relevant rules and regulations,

iii. To ensure regular operation and maintenance of pollution control devices,

iv. To minimize environmental impacts of operations as by strict adherence to the EMP,

v. To initiate environmental monitoring as per approved schedule.

vi. Review and interpretation of monitored results and corrective measures in case monitored

results are above the specified limit.

vii. Maintain documentation of good environmental practices and applicable environmental

laws as ready reference.

viii. Maintain environmental related records.

ix. Coordination with regulatory agencies, external consultants, monitoring laboratories.

x. Maintain of log of public complaints and the action taken

The purpose of environmental monitoring is to evaluate the effectiveness of implementation of

Environmental Management Plan (EMP) by periodically monitoring the important environmental


9/35

parameters within the impact area, so that any adverse affects are detected and timely action can

be taken.

Description of the Site :

The land identified for the proposed project is 42 acres. The major portion of land acquired for

the proposed site is unpopulated, partially cultivated, with some thorny bushes and has no forest

land. General soil characteristics are suitable for installation of the plant. There are no national

parks, wildlife sanctuaries, archaeological sites, military areas/establishments, airports, in the

study area.

Under this it is required to monitor ambient air quality, noise levels, groundwater quality, and

solid wastes in accordance with an approved monitoring schedule. The monitoring protocol and

location selection will have to done carefully. A suggested monitoring protocol, based on the

expected impacts is as under,

At start of the project a basic base line survey of the main factors i.e Ambient Air

Quality, Ambient Noise, Surface Water Quality and Ground Water Quality and depth of Water Table

should have been conducted by Construction agency. It appears that the same is missing. The project is at

quite initial stage so this is the first responsibility of the construction agency to arrange this tests / survey

for generation of base line data with respect to present air quality, water quality, noise level, soil

quality, ecology, socio-economic and meteorology etc by some competent agency and submit report

for record and future comparison to study / establish the effect of construction activities on environment.

Afterwards for the effective monitoring the following tests should be conducted periodically and report be

submitted for critical analysis and recommendations suggestion so that environmental impact is withincontrollable / permissible limits.

OBJECTIVE OF EIA AND EMP REPORT

The aim of this EIA study report is to take stock of the prevailing quality of environment, to

assess the impacts of construction activities on environment and to build appropriate

environmental control measures to minimize adverse impacts and to maximize beneficial

impacts. The following major objectives have been considered:

Assess the existing status of environment. Assess the impacts due to the proposed activity. Suggest pollution control and ameliorative measures. Prepare an action plan for implementation of suggested ameliorative measures.

Suggest a monitoring programme to assess the efficacy of the various adoptedenvironmental control measures.

The first step in environmental impact assessment is to list all the potentially significant

environmental impacts. These are then examined critically and the major impacts (both negative

and positive) are analyzed in detail for the EIA.

Scope of the Study

The scope of the study broadly includes:

a) Collection of base-line data on Physico-chemical, ecological and socio-economic

aspects of environment considering the following attributes: Meteorology Air Pollution Noise Pollution Water Pollution (both Surface and Ground Water) Soil Characteristics Ecology (Flora and Fauna) Socio-economics


11/35

b)Evaluation of incremental levels of pollutants in the study area due to the proposed

project.

a) Prediction of impacts on the various environmental attributes by using scientifically

developed and widely accepted environmental impact assessment methodologies.

b) Preparation of Environment Management Plan (EMP) to mitigate the predictedImpacts.

c) Identification of critical environmental attributes required to be monitored during the

project execution and to suggest post project monitoring.

d) Identification and assessment of risk and hazard associated with the activities of the

proposed plant.

Methodology for EIA

The study comprises collection of relevant data. The study should covers at least an area of 10

km. radius around the proposed project site. The study covers the aspects of air, water, noise,

biological environment, and meteorology, demographic and socio-economic features of the study

IMPACT ASSESSMENT AND MITIGATION MEASURES

The construction and operational phase of the proposed project comprises various activities eachof which may have an impact on environmental parameters. Various impacts during the

construction on the environment have been studied to estimate the impact on the environmental

attributes and are discussed in the subsequent sections. The probable impacts of each of these

activities on various sectors of environment have been mentioned here.

The impact during construction will be localized and short term with permanent changes in the

land use of project site as compared to the current conditions. Impact will be primarily related to

the civil works and less intensive impact is expected during erection of the equipment and trial

operation. The details of the activities and probable impact are discussed blow.Impact on Land-use

The land identified for the proposed plant is 42 Acres. Land-use and land-cover of the proposed

plant area will be changed into industrial land use and the changes will be permanent in nature.

Thus construction activity will bring in certain immediate changes in the land use pattern of the

proposed project area. The major portion of land acquired for proposed site is unpopulated, with

some thorny bushes and has no forest land, so the impact on land use pattern will be minor.

Impact on Land

Soil disturbances and impacts on local geology will occur mainly because of site preparation

activities and disposal of excavated or scrapped materials. Secondary effects may occur due to

erosion and windblown fugitive soil. The soil layer will also be disturbed because of the

proposed activity.

Temporary labor colonies, with adequate potable water and sanitary facilities shall

be provided in the areas already acquired for the project.


13/35

This will be only a temporary change (restricted to construction period). After

construction phase is over, the area acquired by labor colonies shall be reverted

back as per the requirement for other purposes.

The Potential Sources of impact and Mitigation Measures on land environment are

highlighted in the following Table .Potential Environmental Impacts on Land Environment

Controls through

EMP & Design

Construction debris will be collected and

suitably used on-site as per construction waste

management plan.

Impact Evaluation Impact will be local as any waste generated

will be reused for construction activities.

Impact is insignificant.

Impact on Soil

All major construction activities tend to create certain changes in the soil of the core area.

Excavation denudes the topsoil and makes it loose. Destruction of topsoil leads to

reduction of fertility and removal of vegetation cover with associated hazards of the soil

erosion. During storms, some of the excavated soil and construction material such as

sand etc. would be blown up in the air and dispersed around the project site, some would

also tend to be driven into the soil and clog inter-granular spaces. However, in order to

minimize such impacts, appropriate soil conservation measures would be undertaken.

Top-soil shall be preserved and reused in green areas. Vegetation cover would also be

replaced by planting and surfing wherever feasible. Short term, localized impacts are

anticipated on the soil quality of the core area during the construction stage and no impact

is envisaged on the surrounding area.Preservation of top soil: During construction, soil becomes unconsolidated due to

removal of stabilizing material such as vegetation and disturbance of stabilized existing

grade resulting in loss of top soil and also deposition in the undesirable places. A soil

erosion and sedimentation control plan to be prepared prior to construction and should be

applied effectively. Measures for preservation of topsoil are mentioned in the Soil

resource section above.


14/35

Topsoil removal and preservation shall be mandatory for development projects larger

than 1, 00 hectare (Source: National Building Code 2005). Topsoil shall be stripped to a

depth of 200 mm from areas proposed to be occupied by buildings, roads, paved areas

and external services. Top soil shall be stockpiled to a height of 400 mm in pre

designated areas for preservation and shall be reapplied to site during plantation of theproposed vegetation. Measures should be applied to control erosion of preserved top soil.

Top soil shall be separated from sub-soil debris and stones larger than 50 mm diameter.

Human activities during construction can accelerate erosion by removing vegetation,

compacting or disturbing the soil, changing natural drainage patterns, and by covering the

ground with impermeable surfaces (pavement, concrete, buildings). When the land

surface is developed or hardened in this manner, storm water and snowmelt cannot seep

into or infiltrate the ground. This results in larger amounts of water moving more

quickly across a site which can carry more sediment and other pollutants to streams and

rivers. (Source: Chapter 3, EPA) Disruption to the natural hydrology of the site could be

minimised by reducing impervious cover, increasing on site infiltration and managing

storm water runoff.

Mitigation options When opening the site, care should be taken to keep vegetation clearing at a

minimum.

To keep the damage to topsoil minimum, excavators must be used for

construction. The excavated material such as topsoil and stones should be

stacked at safe places for reuse at a later stage of construction.

Prevent soil erosion for large sites during construction by providing

sedimentation basin, contour trenching, mulching, as required. Some generic

soil erosion control measures are described below:

Soil erosion and sedimentation control measures On the proposed site the net imperviousness of the site should not exceed the

imperviousness factor as prescribed by the National Building Code 2005; Part9 (Plumbing services) Section 5.5.11.2.1.

Preserving existing vegetation or revegetating disturbed soils is one of the

most effective ways to control soil erosion.

There are two types of soil erosion control:

Temporary controls provide cover to the soil for a short period of time, till

the permanent measures are adopted. These are usually applicable during

construction.


15/35

Permanent controls These measures are incorporated on soil, when

activities that disturb the soil are over. These measures could be applicable

post construction in the proposed landscape plan.

Impact and Mitigation Measures on Air Quality

Dust will be the main pollutant affecting the ambient air quality of the area during the

construction phase. It will be generated during excavation, back filling, hauling and

vehicular movement of trucks, dumpers and construction machinery. Special care, as

mentioned below shall be taken to control dust emission from vehicular movement,

stockpiles and other construction activities:

In order to minimize the atmospheric generation of dust and gaseous emissions

through vehicular traffic and exhaust emissions, only properly maintained

certified vehicles shall be deployed at site.

The building material shall be adequately covered while transporting through

trucks .

Suitable surface treatment to roads shall be provided to ease the traffic flow. Sprinkling of water on roads shall be regularized to reduce uncontrolled dust

generation.

Extensive tree plantation shall be carried out along the plant boundary and at some

identified area within the proposed site to control spread of fugitive dust emission

that will occur due to construction activity, like handling of material and

transportation within the plant premises.

Aggregates and sand will be stockpiled at suitable places (after stabilizing the

surface), near the boundary wall so that the wall acts as windshield.

In case the height of stockpiles exceeds that of the boundary wall then additional

windshields of adequate height (preferably with tin sheets) will be provided.

To prevent dust nuisance from the stockpiles it will be covered with plastic sheet,

wherever required.

Fugitive dust emission during dry weather conditions, arising out of the

excavation, leveling, transportations and stockpiling activities shall be controlled

by water sprinkling.

Cement will be stocked inside covered sheds only.

With these provisions, only short term, localized impacts are anticipated due to dust

emissions during the construction stage.


16/35

Impact on Ambient Noise Level

Noise is typically defined as "unwanted sound", sound being the human sensation of pressure

fluctuations in the air. Sound levels are expressed in decibels (dB) on a logarithmic scale, where

0dB is nominally the "threshold of hearing" and 120dB is nominally the "threshold of pain".

Noise can seriously harm human health and interfere with peoples daily activities. The main

health risks of noise identified by WHO are:

Pain and hearing fatigue; Hearing impairment including tinnitus;

Annoyance; Interferences with social behaviour (aggressiveness, protest and helplessness); Interference with speech communication; Sleep disturbance and all its consequences on a long and short term basis;

Cardiovascular effects; Hormonal responses (stress hormones) and their possible consequences on human

metabolism (nutrition) and immune system; Performance at work and school.

Noise generally radiates in all directions, but can bend around and over walls and buildings

and can reflect back from solid surfaces. Significantly careful positioning of noisy plant and

equipment can be very effective in reducing noise levels.

Noise generated by construction activities particularly in urban areas can impact on any adjacent

residential and indeed commercial areas, such impacts can be even more severe at

night. Construction site noise can also be a health hazard for those who are working on site.

Construction Activity Sound pressure in dB(A)

Rock drill 110

7hp road roller on concrete at 10m 100

Scaffold dismantling at 10m 80

5hp power float at 7m 70

Typical office 60It is significantly less expensive (unit cost per decibel reduction) to make noise-generating

processes quieter than to make a barrier to screen the noise.

Noise levels can be lowered by eliminating or reducing the noise at source with the use of noise-

control enclosures, absorbers, silencers and baffles and by the use of personal protective

equipment, such as earmuffs. Where technical methods are insufficient, noise exposure may be

reduced by use of hearing protection and by administrative controls -- such as limiting the time


17/35

spent in noisy environment and scheduling noisy operations outside normal shifts or at distant

locations.

Essential elements of environmental noise control programmes are education and training of the

workers to minimise noise generation on a site.

In order to find out the impact of plants construction noise at a receptor point, thecomposite Ldn and plants construction equipment noise (L c) over distances has been

computed by applying standard noise propagation and addition formula (Para, 4.3.3.1);

the values are given in Table 4.3 with following abbreviations:

Ldn = Background day-night noise level = 51.8 dB (A) (Chapter 3, Table 3.5.4)

Lc = Composite noise in dB (A) of construction equipments (2 or more equipments

running simultaneously.

The reduction in cumulative noise (L c+Ldn) over distances for generator, loader and

concrete mixer, clubbing with background noise have been plotted in Figure 4.1.

Lc= Composite noise of generator (96 dB (A)), loader (104 dB (A)) and concrete mixer(105 dB (A))

Ldn=Back ground day-night noise; 51.8 dB (A)

Figure 4.1: Reduction in Cumulative Noise (L c+L dn ) over Distance

Impact due to Individual and Cumulative Construction Equipments

Operation Noise

It may be seen from Table 000 that:

Beyond, approximately, 200 mt, no construction equipment (S. No. 1-13) shall

contribute more than 1 decibel noise (i.e. >52.8 dB(A)) to the back ground noise

(51.8 dB(A)) of the study area. This distance is very much within the plants

premises.

Between 200 mt to 2 km, there shall be insignificant contribution of 1

dB (A) to the ambient noise beyond 200mt and between 200 m to 2 km there shall

be insignificant contribution of


20/35

The composite noise, L c of generator, concrete mixer and loader is not

contributing >1 dB (A) to the ambient noise beyond 300mt and between 300 mt to

2 km there shall be insignificant contribution of


21/35

The noise level near the construction equipments and nearby areas shall be

regularly monitored. In case of higher noise, appropriate action shall be taken to

bring it down to tolerable limit.

With these measures it may be ensured that the noise level during construction phase

surrounding the core area shall be controlled to permissible standard. However, the noisegeneration will be confined within the immediate surrounding areas of the construction

site and only for a short term. Localized and reversible insignificant impact is expected

due to noise emissions generated during the construction stage.

Impact on Water Environment

The water requirements during the construction phase of the proposed plant would be

small as construction will be more related to mechanical fabrication, assembly and

erection. Following action shall be taken to avoid any impact on the surface and ground

water quality during construction phase.

1. Storm water drains will be made immediately after starting construction activity.

The drains will be properly aligned in conformity with the site drainage pattern so

that the alteration is kept to the minimum and flooding or soil erosion does not

occur.

2. Sedimentation pits will be provided at appropriate location to trap the silt laden

runoff water and prevent excessive silt from going outside.

3. The storm water drains will be suitably diverted to the water reservoir to collect

the runoff. This stored water will be utilized for construction purposes.

4. No wastewater will go out of the plant premises during the construction stage and

contaminate the surrounding water bodies in any manner.

5. Temporary sanitation facilities (septic tanks and soak pits) will be set-up for

disposal of sanitary sewage generated by the workforce.

6. Rainwater harvesting/recharge structures will be made at suitable points to collect

the excessive runoff generated from the paved areas of the plant site and divert

them for recharging the groundwater table.

With the above measures, it may be envisaged that overall impact on water environment during

construction phase due to proposed project shall be insignificant.

Impact on Flora & Fauna

The initial construction work at the project site involves site clearance. The site is almost

barren land with some thorny bushes and very scanty vegetation cover is observed at the

plant site. No ecologically sensitive floral species exist in the proposed site. As such the

construction activities shall have insignificant impact on the flora. Moreover greenbelt


22/35

will be developed phase wise during construction to improve the aesthetic value in the

area and to screen out the fugitive dust generated during construction.

No wild life sanctuary, national park or faunal species of significance have been observed

in the study area. Similarly, no domestic animals were encountered at the proposed site;

the reason may be the lack of food, water or shelter inside the proposed site. Few speciesof birds are sighted in and around the site. Plantations will improve the habitat of

avifauna.

Short term, localized insignificant impact on ecology is anticipated during the

construction stage.

Socio-Economic Impacts

The project shall create both direct or indirect job opportunities. This indicates the

availability of sizeable manpower locally, required for the construction activity. There

shall also be migration of semi-skilled/skilled labor force from outside in the study area

during construction phase, which may put some pressure on the local settlements and

resources. However temporary accommodation, with necessary facilities, shall be created

on-site. Also this shall be temporary in nature and limited to the construction period.

However, the flow of workforce and material will affect the socio-economic status of the

people in the area. Growth/expansion of shops, dhabas , small hotels and other allied

services will also open up avenues for employment. The subsequent improvement in the

status of the people will also help in increasing the health and education status of the

people. As such the positive impact is envisaged on socio-economic aspects of the

surrounding population.

It may also be highlighted that there is no cultural heritage site (temple, mass bathing site

during religious festivals, etc) is located close to the project site that could be affected

during the construction stage. As such positive impact is anticipated on the socio-

economic status of the people residing, particularly, in the vicinity of the proposed plant

area.

Impact on Workers Health, Sanitation and SafetyThe health of workers will be checked for general illness-first time upon employment and

thereafter at periodic intervals, as per the local laws and regulations. Health centre and

ambulance facility will be provided to workers. Workers exposed to dust and noise will

be given personnel protective equipment like nose masks, face shields, ear plugs, etc. Job

rotation schemes will be practiced for over-exposed persons. Facilities planned for

construction workers include temporary shelters, fuel, toilet, safe drinking water, medical


23/35

facilities and crche. Insignificant impact is anticipated on the workers health and safety

during the construction stage.

4.2.9 Solid Waste Disposal

Solid waste during the construction phase will consist primarily of scrapped building

materials, excess concrete and cement, rejected components and materials, packing andshipping materials (pallets, crates, Styrofoam, plastics etc.) and human waste. However, it

is expected that there will be generation of sizeable amount of garbage, for which suitable

disposal methods shall be devised:

Careful design, planning and good site management would minimize waste of

materials such as concrete, mortars and cement grouts.

Construction wastes will be segregated as much as possible at site itself to

increase the feasibility of recycling concrete and masonry as filling material and

steel pieces as saleable scrap.

Litter collection points will be established around the work sites and disposed off

through the facility of the local authority.

Empty packaging materials, drums, glass, tin, paper, plastic, pet bottles, wood,

thermocol and other packaging materials will be disposed through recyclers

(locally called kabadis).

The construction spoils including top soil will be temporarily stored at designated

dumpsite located inside the plant premises. Later on these wastes will be used for

land filling, leveling, developing garden, lawns etc., within the plant premises.

Impact on Sensitive Targets

The sensitive targets include the following:

1. Religious and historical places

2. Archaeological monuments

3. Scenic areas

4. Hill resorts

5. Beach resorts

6. Health resorts

7. Estuaries

8. Biosphere reserves

9. National Parks and sanctuaries

10. Natural lakes, swamps

11. Seismic zone

12. Tribal settlements


24/35

13. Areas of scientific and geological interests

14. Defense installations

15. Border areas (international) and

16. Air Ports

There exist no such targets and as such there shall be no impact on any of the above targetdue to proposed plant activities.

Overall Impact Statement

The plant site is basically a land devoid of population. No reserve forest or important

historic place is situated at the proposed site or in the vicinity. There exist no notified

rare species of flora in the study area which would be affected due to the plant operational

activities.

Since all necessary pollution control measures to maintain the emission levels of dust

particles, Sulphur Dioxide, Nitrogen Oxides and noise within the permissible limits

would be taken and all generated liquid effluent after due treatment shall be in-house

utilized, there shall be insignificant impact on the surrounding area.

Other provisions for pollution such as on line monitoring and control, to ensure

compliance with the requirements of the State Pollution Control Board will be made.

It is evident from above that the various mitigation measures proposed to be adopted

during the construction phase shall reduce the scale of environmental impacts to

insignificant level.


25/35

ENVIRONMENT MANAGEMENT PLAN

Environmental Management Plan is the key to ensure that the environmental quality of thearea does not deteriorate during construction period of the proposed plant under study. The

probable impacts during construction stage have been discussed in above paragraphs.

Management plan consists of the following activities:

Specific action plan for implementing mitigation measures Monitoring of Environmental Quality Rainwater Harvesting Training Statutory requirements and Implementation Documentation Green Belt Plantation Social Responsibility

Environment Management Plan (EMP) is aimed at mitigating the possible adverse impacts of a

project and for ensuring maintenance of existing environmental quality. Formulation and

implementation of EMP also reinforces beneficial impacts of a project. The EMP covers all

aspects of planning, construction and operation of the project, which are relevant to the

environment. It is essential to implement the EMP right from the planning stage and then

continuing it throughout the construction and operation stages. Therefore the main objective of

the EMP is to identify the project specific activities that would have to be considered for

investigation of the significant adverse impacts and the mitigation measures required.

Environment Management Plan during Construction Phase

The major construction activities that have potential environmental impacts involve pre-

construction site preparation and installation of temporary and permanent facilities to meet the

future requirements for success of the project. However, except for permanent change in locallandscape and land use pattern of the project site, the constructional phase impacts are temporary

and localized phenomena.

To implement the Environment Management Plan (EMP), a structured Environment

Management Group (EMG) shall be created. The EMG shall undertake regular monitoring of

the environment during the construction (as well as operation phase) of the project. It shall also

check that the stipulated measures are being satisfactorily implemented. It shall also co-ordinate

with local authorities and ensures filing of relevant reports to statutory bodies.


26/35

The success of environmental control measure can only be understood by proper monitoring of

the environmental parameters. A detailed monitoring for different environmental parameters

will be carried out as per direction of West Bengal Pollution Control Board. Monitoring

methodologies will follow standard methods prescribed by Central Pollution Control

Board (CPCB), Bureau of Indian Standards (BIS) etc. Major monitoring parameters arediscussed below.

Periodic Preventive Maintenance

All pollution control, monitoring and safety equipments shall be periodically checked

and calibrated.

Safety & Health

Periodic monitoring of the health of the workers will be carried out as required by

Factories Act for safety, mock drill of the concerned employees for handling the

emergency situation will be carried out, as apart of On-Site Emergency Plan. Air

Quality at the work place will be measured intermittently.

Green Belt Development

There will be all efforts for improving the environmental quality of the plant complex

through tree planting in organized manner. The trees will be planted inside the plant in

vacant areas, along the boundary walls in rows to develop a wide green belt and also in

dust prone area along with vacant area for landscaping including gardening.

The predominant species list for greening is as follows:

Acacia auriculaeformis (akasmoni), Alstoniascholaris (chatim), Cassia fistula

(bandarlathi), Lagerstroemeaparviflora (jarul), Terminaliacatappa (kathbadam),

Spathodeacampanulata (spathodea), Grevelliarobusta(silveroak), Delonixregia

(gulmohar), Peltophorumpterocarpum (radhachura), Gmelinaarberea (gamar) etc.Rainwater Harvesting

Rainwater harvesting is now an important component of wise resource use and

environmental management During construction / operation of the plant following

approach will be taken to implement the Rain water harvesting plan. Rain water from

the roofs of all the Station Buildings of the units, storm water drains adjoining the roads

of the plant shall be collected in a rainwater collection tank. All storm water drains of

the main plant area shall be connected to the rain water collection tank. Rain water

collected in the rainwater tank is to be utilized for further use. This is achieved byinstalling a suitable pump at one end of the tank. This shall pump the collected water to

the synthetic PVC tank installed on the roof of superstructures Building. The size of the

synthetic tank shall be suitably sized based on the rain fall intensity and the runoff

there-of. Additional tanks could be installed as and when the underground tanks are

added. PVC pipe is proposed for pumping water from the rain water collection tank to

the tanks on top of the buildings.


28/35

Collected water from the synthetic tank is distributed by gravity to desired

locations for non-potable use like gardening, cleaning etc.

Training

Training is of much importance in environmental management. Environmental

science is a developing subject and the people implementing environmental strategiesshould remain up to date with the environmental control processes. The person in

charge of the environmental jobs should attend suitable training courses. Besides, there

shall be training programme for the general employees at different level.

Statutory Requirements and

Implementation

Each industry needs to meet a number of statutory requirements under Water

(Prevention & Control of Pollution) Act; Air (Prevention & Control of Pollution) Act;

Environment (Protection) Act; Hazardous Waste (Management &Handling) Rules;

Manufacture, Storage and Import of Hazardous Chemicals Rules etc. Company has

also to submit yearly Environmental Statements. Environment Management plan

will ensure that these entire statutory requirements are met in time.

Documentation

Documentation is an important step in implementing Environmental Management Plan.

All statutory norms should be kept at one place for quick references. All monitoring

results should be kept at selected folders which can be easily accessed. The presentation

of the results should also be planned. Graphs and diagrams can be used to show the

trend in environmental quality or achievement. Documents should be kept at a declared

position.

Documentation will include

o Major technical information in operationo Organizational Chartso Environmental Monitoring Standardso

Environmental and related legislationo Operational Procedureo Monitoring Recordso Quality Assurance Plan for Monitoringo Emergency plans

Safety and Infrastructure Services for Personnel

Manpower required during construction phase is expected to be approx. 100.

Construction personnel shall be made aware of possible hazards and safety measures that


29/35

need to be taken during construction activities through proper training. Adequate

personal protective equipments such as dust masks, goggles, earplugs/earmuffs, safety

gloves, safety belts, shoes with toe protection, gumboots shall be made available at the

construction site and the construction company shall strictly observe applicable safety

norms.Temporary accommodation facilities shall be created for staff and construction workers

and necessary arrangements shall be made to meet the basic requirements, as highlighted

below:

Temporary shelters Canteen facility Fuel facility (so that they do not cut any fuel wood) Safe drinking water facility

Sanitation/toilets with septic tank Rest room Medical facility Crche MSW disposal facility at nearest municipal waste collection site.

Land Environment Management

Topography of the proposed site is almost flat and no major filling/cutting works are

anticipated except for the purpose of foundation. Dust generated due to earthwork

including excavation and transportation activities, especially during dry weather

conditions, shall be controlled by water sprinkling. The earth generated during excavation

shall be used in refilling, leveling and landscaping the area.

No nallas or water courses are present at the project site. Natural drainage pattern shall

not be disturbed as far as possible.

The approach road to project site shall be appropriately widened to facilitate vehicular

movement.

Before starting-up of earthwork during construction, work on development of the

greenbelt area shall be initiated and plantation of trees taken up.

The measures, which would be followed to prevent soil erosion and contamination, are

summarized below:

Maximize use of top soil for landscaping To prevent soil contamination by oil/grease, leak proof containers shall beused for

storage and transportation of oil/grease. Wash off from the oil/grease handling


30/35

area shall be drained through impervious drains and treated appropriately before

disposal.

Removal of as little vegetation as possible during the development Plantation of trees in green belt area.

Handling of Construction EquipmentVehicles and machinery deployed for construction work, transportation of debris and

other materials shall be properly maintained and handled to minimize emissions of

particulates and gaseous pollutants. The vehicles maintenance shall be monitored

regularly so as to avoid noise pollution and accidental spillage of oils and greasy matters.

Loading and unloading operations and movement of trucks shall be properly regulated to

minimize the impact of noise on the personnel engaged in civil, mechanical and erection

works.

Solid Waste during Construction Phase

A. Non-Hazardous Solid Waste

i) Construction Debris: Construction debris is bulky and heavy and re-utilization

and recycling is an important strategy for management of such waste. As concrete

and masonry constitute the majority of waste generated, recycling of this waste by

conversion to aggregate and as a sub-base for road construction can offer benefits

of reduced landfill space.

ii)Metal Scrap : Metal scrap from structural steel, piping, concrete reinforcement

and sheet metal work shall be removed from the site by construction contractors.

A significant portion of wood scrap can be reused on site. Recyclable wastes such

as plastics, glass fiber insulation, roofing etc shall be sold to recyclers.

B. Hazardous Waste

Construction sites are sources of many toxic substances, such as paints, solvents, wood

preservatives, pesticides, adhesives and sealants. Hazardous waste generated during

construction phase shall be stored in sealed containers, labeled, and disposed of as

required by the Hazardous Wastes Management and Handling Act Amendment Rules(MoEF, 2003).

Some management practices to be developed are:

Paintbrushes and equipment for water and oil based paints shall be cleaned within

a contained area and shall not be allowed to contaminate site soils, watercourses

or drainage systems.


31/35

Provide adequate hazardous waste storage facilities, hazardous waste collection

containers are conveniently located and designate hazardous waste storage areas

away from storm drains or watercourses.

Potentially hazardous waste shall be segregated from non-hazardous construction

site debris. All hazardous waste shall be clearly labeled.

Air Quality Management

The dust nuisance created by the excavation, leveling and transportation activities shall be

properly controlled by

Sprinkling water on roads, Providing dust arresting panels/sheets, Tree plantation to act as dust barriers,

Regular removing of construction waste material, Proper storage of building material in sheds or under plastic covers, stockpiling

along predominant wind direction, maintaining stockpile height close to boundary

height (and use of tin sheets to provide wind barrier in case height exceeds

boundary height),

Use of cover sheets on trucks used for transportation, Avoiding of truck overloading and implementation of speed limits for vehicles. Emissions from vehicles and construction equipment shall be controlled by

ensuring that vehicles used during construction undergo periodic pollution control

checks and use cleaner fuels.

The ambient air quality shall be monitored at the project site every quarter for

RSPM, SPM, SO 2 and NO X.

Noise Level Management

Noise resulting from operation of construction machinery and vehicular movement,

though localized, may constitute an additional environmental stress.

Recommended mitigation measures for noise pollution are:

Good maintenance of vehicles, construction equipment and roads. Restriction of noisy construction activities to day time only. Plantation of trees in the greenbelt area and around the plant boundary to attenuate

the noise.

Provision of earplugs and earmuffs to workers for work in unavoidable noisy

operations.

Acoustic housing for DG sets.


32/35

The Ambient Noise Levels shall be monitored quarterly. In case a source is found

making significantly higher noise, immediate action shall be taken to bring down

its noise to a tolerable limit

Water Quality Management

The mitigation measures recommended for water quality management are as follows: The open drains carrying construction waste-water shall be collected in cemented

trenches for reutilization to a greater extent.

Storm water drains shall be constructed for storm water collection into a reservoir,

water from which shall be used in construction activities and green belt

development.

Soak pit for construction workers/canteen. The vehicle maintenance area shall be located in such a manner so as to prevent

contamination of ground water by accidental spillage of oil. Oil and grease trap

shall be provided at equipment maintenance area.

Unauthorized dumping of waste oil shall be prohibited. Site of deposition of building material wastes shall be cordoned. Groundwater quality of the site area shall be regularly monitored preferably once

in a quarter during the development period.

Ecological Management

In order to prepare the site for the construction work, there might be cleaning of shrubs

present at the site. To compensate, proper landscaping and tree plantation activities shall

be initiated during construction phase itself. More than 30% land has been earmarked for

green belt development. Large size species of trees shall be planted at the time of

preparation of site so that they would grow to considerable size by the time of

commissioning of the proposed project. Construction workers shall be provided domestic

fuel (kerosene oil) so as to prevent cutting of trees for firewood.

Socio-economic

Any construction activity shall benefit the local population in a number of ways. Theproject shall generate both direct and indirect employment opportunities. In addition,

development of infrastructure in the area, and other secondary developments shall provide

ample opportunity to the locals to up-lift their living standards.


33/35
