described below:

Stage -I

Review of design and operational information of the Project through various

plans, drawing and identification of sources of major potential impacts.

Stage -II

An initial review of the project site and status of the physical environment around

the project site vicinity;

Understanding regarding project design and operation as well as macro

environmental aspects. The major issues needed to be addressed with due care were identified

and monitoring plan for the environmental baseline was prepared;

Integrated Township



CHAPTER 1


Baseline environmental assessment was conducted within the study area of 10 km

radius around the project site;

Intense monitoring and primary field data collection of environmental

components viz. Micro-Meteorological Condition, Ambient Air Quality, Water (Surface and

Ground water) use and its Quality, Soil Quality, Noise Level, Traffic Volume etc.;

Survey study was carried out in the study area to assess the status of flora & fauna

and socio-economic profile of the study area; and

Information was also collected through Secondary sources like Department of

Census, Local and City Offices, National Institutions (Survey of India, National Information

Centre etc.), District Head Quarters and other Government Offices etc. as well relevant

Published Literatures.

Stage –III

Compilation of the Environmental Baseline of the Study Area.

Stage –IV

Assessment of Environmental Impacts by predicting the scale and extent of changes

associated with the project and their subsequent effects on the environment against the

environmental baseline condition, and evaluating the significance of such impacts against

accepted criteria.

Stage -V

Identification and preparation of measures to mitigate significant impacts (evaluated from

the impact prediction process) by proposing applicable alternatives and control measures; and

Finally, development of appropriate Environmental Management and Monitoring Plan to

audit and ensure that the proposed mitigation measures are in place and effective.

1.14 EIA METHODOLOGY

The project may have impact on environment attributes such as air, water, noise level, soil

quality, hydrology and drainage pattern and meteorology of surrounding environment due to on-

going project. In assessing the environmental impact, collection, collation and interpretation of

baseline data is of prime importance. Long term data sets help us to get better assessment. The

objective of EIA is to predict and address potential environmental problems/concerns at an early

Integrated Township



CHAPTER 1


stage of project planning and design as the infrastructure development has adverse impact on

environment. EIA/EMP assists in the decision making process by identifying the key impacts/

issues as a results of the activities and formulating mitigation measures, leading to an

improvement in environmental quality.

In order to achieve these objectives, the following procedures have been adopted for the study:-

Collection, collation and analysis of regional and local environmental status for various

environmental attributes (like topography, geology, ambient air quality, meteorology, water

quality, noise level, soil characteristics and land use, transport, settlement status and socio

economic aspects etc.) to assess base-line status of the project.

Identification of environmental impacts leads to assessment of impact on the base-line

status which will decide the feasibility of the project and suggests mitigation measures to control

pollution with respect to standards applicable for the area.

Evaluation of impacts leading to preparation of environmental management and

monitoring plan.

Addition study will cover disaster management plan during construction and operation

phase of the project.

Environment Monitoring Plan and annual budget – one time and recurring cost of EMP

will be discussed in Separate chapter.

This report is based on scientific principles and professional judgment with resultant subjective

interpretation. Professional judgments expressed herein are based on the available data and

information.

of recycled water is approx. 80% of the wastewater and during non rainy season 1962 KLD

treated water will be used for flushing, and horticulture and extra 907 KLD will be used in

nearby construction, Irrigation, Nala etc. During rainy season (since there is no requirement of

treated water for horticulture) will be used in nearby construction, Irrigation, Nala.

2.9.2 Sewerage System

MBBR TECHNOLOGY

An external sewage network shall collect the sewage from all units, and flow by gravity to the

sewage treatment plant.

Following are the benefits of providing the Sewage Treatment Plant in the present

circumstances:

Reduced net daily water requirements, source for Horticultural purposes by utilization of the

treated Sullage.

Reduced dependence on the public utilities for water supply and sewerage systems.

Sludge generated from the Sewage Treatment Plant shall be rich in organic content and an

excellent fertilizer for horticultural purposes.

CHAPTER 2


(b) B.O.D. : <10 mg/l

(c) C.O.D. : <60 mg/l

(d) Total Suspended Solids : <20 mg/l

c. Treatment Technology

Moving bed biofilm reactor technology is based on the principle of attached growth process.

Raw sewage will be collected under gravity into the equalization tank after allowing to pass

through the bar screen. Screens will be provided in screen chambers and it will be manually

cleaned by going down to a platform. The bar screen, by removing coarse solids from the sewage

help in protecting the raw sewage pump.

Fully submersible centrifugal non clog sewage handling pump will be provided in the collection

cum equalization tank to pump the collected sullage to the next MBBR tanks. Automatic level

controller will be provided in the tank to turn the pump off at the low water level in the tank and

to start the pump when water level is high automatically. Air will be introduced in this tank to

prevent any potential foul smell problem & to provide the mixing of sullage to avoid the

sedimentation of solids in this tank. Air Grid used for aeration purpose shall be non-clog.

The sewage collected in equalization tank is pumped the moving bed bioreactor. There shall be

two nos. of bioreactors in series for the efficient working and removal of BODs for the required

retention time. The process inside the moving bed bioreactors consists of adding small

cylindrical-shaped polyethylene/polypropylene carrier elements in aerated basins to support

biofilm growth. The small cylinders are provided with a cross inside the cylinder and

longitudinal fins on the outside. The biofilm carriers are maintained in the reactor by the use of a

perforated plate with appropriate slot at the tank outlet. Air agitation or mixers are applied in a

manner to continuously circulate the packing. The packing may fill 25 to 50 percent of the tank

volume. Specific surface area of the packing is about 450-500m2/m

3 of bulk packing volume.

The sullage from first bioreactor flows by gravity through the perforated plate/mesh to the next

bioreactor kept in series. Inside the bioreactors, aerobic bacteria grow in an attached growth from

around the moving plastic media inside the reactors. The bacteria have to reduce BOD & COD

Integrated Township



CHAPTER 2


of sullage in the presence of oxygen provided through the air grids located at the bottom of the

reactors. The Process does not require any return activated sludge flow or backwashing.

From the bio-reactors, the effluent passes by gravity into the clarifier (Tube Settling Tank).

Clarifier will be a hopper bottom sedimentation tank provided with appropriate size PVC tube

deck media. The suspended solids will settle at the bottom of the tank & clear supernatant will

overflow to filter feed tank through outlet launder. The collected sludge at bottom shall be

transferred through pumps to sludge holding tank.

The clear supernatant after clarifier will be collected in to filter feed tank. This tank will act as

housing tank for filter feed pumps. The clarified & dis-infected water will be then fed to

filtration unit.

Filtration unit consisting of Dual Media sand filter, activated carbon filter and ultra filtration

system (optional) will remove the residual impurities such as odor/color, suspended solids,

BOD/COD. The treated water after the filtration unit will be collected in Irrigation cum Flushing

water storage tank from where it is transferred to flushing water tank at terrace & Irrigation

System.

Excess sludge from the bottom of the settling tank will be removed and transferred to sludge

holding tank. Air grid shall be provided in this tank to avoid conversion into anaerobic

conditions, thickening of sludge and keep sludge in homogenous condition. The digested &

thickened sludge shall be further thickened through Sludge Dewatering System (Filter press with

screw pump) and disposed off periodically through closed tanker or can be reused as manure.

Integrated Township



CHAPTER 2


Figure 2.2: Schematic Diagram of STP

Sewer System

The alignment and slope of the sewer line will follow the road network, drains or natural ground

surface and will be connected to the trunk sewers. The discharge point will be a treatment plant,

a pumping station, a water course or an intercepting sewer. Pumping stations would be provided

at places where the natural slope of the terrain is insufficient to permit gravity flow or the cost of

excavation is uneconomical to do the same.

2.9.3 Re-Use of Treated Wastewater

The domestic sewage will be treated through proposed Sewage Treatment Plant of appropriate

total capacity i.e. 3,720 KLD within the project premises. The recycled water from proposed

Sewage Treatment Plant will be used for the purpose flushing and horticulture.

2.10 RAINWATER HARVESTING

In township development with mixed use of other buildings, each buildings (Plots, Group

Housing, Commercial, Public and semi public buildings) should be having their own self

sustainable design for storm water system with adequate nos, of RWH structure as per norms. At

Integrated Township



CHAPTER 2


the township level we will take care of paved green, roads and any surplus discharge from other

buildings in case sudden downpour. That has been considered 20% of their total runoff.

Rain water harvesting has been catered to and designed as per the guideline of CGWA for the

green paved and surplus discharge from other buildings . Peak hourly rainfall has been

considered as 45 mm/hr. The effective diameter and depth of a Recharge pit 3.20 m, and 2.40 m,

respectively is constructed for recharging the water

The bottom of the recharge structure will be kept 5 m above this level. At the bottom of the

recharge well, a filter media is provided to avoid choking of the recharge bore. Design

specifications of the rain water harvesting plan are as follows:

All gutter ends will be fitted with a wire mesh screen and a first flush device would be

installed. Most of the debris carried by the water from the rooftop like leaves, plastic bags and

paper pieces will get arrested by the mesh at the terrace outlet and to prevent contamination by

ensuring that the runoff from the first 10-20 minutes of rainfall is flushed off.

No sewage or wastewater would be admitted into the system.

No wastewater from areas likely to have oil, grease, or other pollutants has been connected to

the system.

2.10.1 Storm Water Drainage

The storm water collection system for the premises shall be self-sufficient to avoid any

collection/stagnation and flooding of water. The amount of storm water run-off depends upon

many factors such as intensity and duration of precipitation, characteristics of the tributary area

and the time required for such flow to reach the drains. The drains shall be located near the

carriage way along either side of the roads. Taking the advantage of road camber, the rainfall run

off from roads shall flow towards the drains. Therefore, it has been calculated to provide 15

infilteration wells and surplus rainwater will be disposed in Green areas developed as kachha

pond or water body.

1. Since the existing topography is congenial to surface disposal, a network of storm water

pipe drains is planned adjacent to roads.

Integrated Township



CHAPTER 2


2. Storm water system consists of pipe drain, catch basins and seepage pits at regular

intervals for rain water harvesting and ground water recharging.

3. Peak Hourly Rainfall of 45 mm/hr shall be considered for designing the storm water

drainage system.

4. All the other building in township will have their self sufficient RWH Structure.

2.11.3 E-Waste Management & Disposal

"E-waste" is a popular, informal name for electronic products nearing the end of their "useful

life”. E-wastes are considered dangerous, as certain components of some electronic products

contain materials that are hazardous, depending on their condition and density. The hazardous

content of these materials pose a threat to human health and environment. Discarded computers,

televisions, VCRs, stereos, copiers, electric lamps, cell phones, audio equipment and batteries if

improperly disposed can leach lead and other substances into soil and groundwater. Many of

these products can be reused, refurbished, or recycled in an environmentally sound manner so

that they are less harmful to the ecosystem. Reducing e-waste requires that we reduce, reuse,

recycle and recover. The goal is nothing less than zero land fill. Network of scrap dealers will be

motivated to procure from door to door for the smaller quantities.

Only hazardous waste to be generated from project site is used oil from D. G. sets. Used oil will

be stored in HDPE containers and will be disposed as per hazardous waste (Management,

Handling and trans-boundary movement) rules, 2008.

DESCRIPTION OF ENVIRONMENT

3.1 INTRODUCTION

Information on the existing environmental status is essential for assessing the likely environmental

impacts of the project. In order to get an idea about the existing state of the environment, various

environmental attributes such as meteorology, air quality, water quality, soil quality, noise level, ecology

and socio-economic environment have been studied/ monitored.

3.2 STUDY PERIOD

Baseline environmental data generation for air, water, noise and soil quality monitoring around the

project site was conducted from October-December 2015, with an additional 1 month study of January

2016. Apart from field monitoring, additional data was also collected from secondary sources like India

Meteorological Department (IMD), State Pollution Control Board, Census of India and Local Forest

Department etc.

3.3 STUDY AREA

The site development area spreading across 9,60,680 m2 (237.39 acres) is a vacant land earmarked for

development of Integrated Township Project as per Naya Raipur Development Plan 2021. The

probability of impacts from the Integrated Township Project is generally within 2 kms. Field Monitoring

has been carried out beyond 2 km, in case of presence of sensitive receptors. The present report covers

baseline environmental data generated in the study area (5 km radius) all around the project site for land

use and the sample selection for monitoring are done within 5 km radius of the project site. Toposheet

image showing the project site within 5 km surroundings is attached as Annexure VII. For biological

studies, considering the ecological connectivity and widespread habitats of wildlife, a 15 km radius

around the project area has been considered for secondary data collection and the map showing the same

is attached as Annexure V.

CHAPTER 3


The prime objective of the baseline study with respect to ambient air quality is to establish the present

air quality and its conformity to National Ambient Air Quality Standards. This data has been further

used during impact assessment to predict the final air quality. This section describes the sampling

locations, frequency of sampling and methodology adopted for monitoring ambient air quality.

To quantify the impact of the project on the ambient air quality, it is necessary at first to evaluate the

existing ambient air quality of the area. The existing ambient air quality, in terms of Particulate Matter-

10(PM10), Particulate Matter-2.5 (PM2.5), Sulphur-dioxide (SO2), Oxides of Nitrogen (NO2), and Carbon

Monoxide (CO), has been measured through a planned field monitoring.

To assess the ambient air quality level, 5 (five) monitoring stations were set up. Table-3.2 gives location

of the ambient air quality monitoring stations.

3.4.2.1 Monitoring Schedule

Ambient air quality monitoring was carried out twice a week with a frequency of 24 hours for 12 weeks.

3.4.2.2 Methods of Sampling and Analysis

Fine particulate Sampler APM MFC550 was used for monitoring Particulate Matter (PM2.5 and PM10);

gaseous pollutants like SO2, and NO2 was collected by Gaseous Pollutant Sampler APM 433 and CO

was monitored by Serinous 30 CO Analyser with NDIR detector.

3.4.2.3 Method for measurement of Particulate matter, SO2 & NO2

Method for measurement of Particulate Matter (PM10) in ambient air is done by Cyclonic Flow

Technique. Particles with aerodynamic diameter less than the cut-point of the inlet are collected by a

filter. Ambient air at the monitoring location is sucked through a cyclone. Coarse and non-reparable dust

is separated from the air stream by centrifugal forces acting on the solid particles and these particles fall

Integrated Township



CHAPTER 3


through the cyclone's conical hopper and get collected in the sampling cap placed at the bottom. The fine

dust (<10 microns) forming the particulate matter (PM10) passes the cyclone and is retained on the filter

paper. The mass of these particles is determined by the difference in filter weights prior to and after

sampling. The concentration of PM10 in the designated size range is calculated by dividing the weight

gain of the filter by the volume of air sampled. A tapping is provided on the suction side of the blower to

provide suction for sampling air through a set of impingers for containing absorbing solutions for SO2

and NO2. Samples of gases are drawn at a flow rate of 0.2 liters per minute. The APM MFC 550 is used

for PM2.5. This system is a manual method for sampling fine particles (PM2.5 fraction) and is based on

Impactor designs standardized by USEPA for ambient air quality monitoring.

PM2.5 & PM10 have been estimated by gravimetric method. Improved West and Gaeke method (IS-5182

part-II, 1969) has been adopted for estimation of SO2 and Modified Jacobs-Hochheiser method (IS-5182

part-VI, 1975) has been adopted for the estimation of NO2.

3.4.2.4 Method for measurement of Carbon Monoxide – NDIR method

Instrument used: Ecotech Serinus 30 Carbon Monoxide

This analyser is used to measure CO in ambient air, in the range of 0-200 ppm (220mg/m3) to a

sensitivity of 0.05 ppm 55µg/m3). The Serinus 30 combines the benefits of Microprocess control with

Non-Dispersive Infrared Spectrophotometry technology.CO Concentration is automatically corrected for

gas temperature and pressure changes.

3.4.2.5 Results and Discussions

The results of AAQ are given in details in Annexure-IX and summarized in the tabular form. The

results when compared with National Ambient Air Quality Standards (NAAQS) of Central Pollution

Control Board (CPCB) for "Industrial, Residential, Rural and Other Areas" show that the average

values of ambient air quality parameters are well within the stipulated limit.

The results of ambient air quality monitoring are summarized in the Tables below:

3.4.3 Noise Levels

Noise is one of the most undesirable and unwanted by-products of our modern life style. It may not

seem as insidious or harmful as air and water pollutants but it affects human health and well-being and

can contribute to deterioration of human well-being in general and can cause neurological disturbances

and physiological damage to the hearing mechanism in particular. It is therefore, necessary to measure

both the quality as well as the quantity of noise in and around the site.

Integrated Township



CHAPTER 3


3.4.3.1 Methodology

The intensity of sound energy in the environment is measured in a logarithmic scale and is expressed in

a decibel, dB (A) scale. In a sophisticated type of sound level meter, an additional circuit (filters) is

provided, which modifies the received signal in such a way that it replicates the sound signal as received

by the human ear and the magnitude of sound level in this scale is denoted as dB (A). The sound levels

are expressed in dB (A) scale for the purpose of comparison of noise levels, which is universally

accepted by the international community.

Noise levels were measured using an Integrating sound level meter manufactured by Pulsar Instruments

Plc, Model NO. 91 (SL.No.B21625). It has an indicating mode of Lp and Leq. Keeping the mode in Lp

for few minutes and setting the corresponding range and the weighting network in “A” weighting set the

sound level meter was run for one hour time and Leq was measured at all locations.

The day noise levels have been monitored during 6.00 am to 10.00 pm and night noise levels, during

10.00 pm to 6.00 am at all the 4 locations, which covers residential areas, commercial area, industrial

area, Silence area if available within 10 km radius of the study area.

3.4.3.2 Sampling Locations

A preliminary survey was undertaken to identify the major noise generating sources in the area. The

noise survey was conducted to assess the background noise levels in different zones. Gazettes

Notification (S.O. 123(E)) of MoEF dated February 14, 2000 on ambient air quality standards has

different noise levels for different zones viz. project site, industrial, commercial, and residential and

silence zones. Four sampling locations were selected for the sampling of noise levels. The sampling

locations are given in Table-3.3 below:

3.4.4.3 Result & Conclusion:

The results of analysis of ground water are given in Annexure IX.

The water quality in the impact zone was assessed through physico-chemical and bacteriological

analysis of ground water samples. The results have been compared with the drinking water quality

standards specified in IS: 10500. It was observed that all the physico chemical parameters and heavy

metals from ground water samples are below stipulated drinking water standards.

All the ground water samples analyzed can be considered fit for drinking purpose in the absence of

alternate sources

3.4.5 LAND ENVIRONMENT

Land is the most vital resource for sustenance of life and degradations of land due to industrialization,

urbanization and population growth is a matter of concern. Therefore, it is necessary to establish the

existing land use pattern to optimize the land use as well as minimize degradation due to the

developmental activities. Also it is necessary to the landform of the project site and the quality of the

soil as soil erosion further deteriorates the quality of the land. Soil erosion can be prevented by

following methods:

Planting vegetation which stabilizes the soil and prevent erosion.

Applying a layer of mulch/fertilizer to the soil top which allows the soil to slowly soak up water,

protects against rain impact.

Using Geotextiles which helps in stabilizing soil.

3.4.5.1 Topography

The landform of the project site is a plain land with average elevation of about 313.5 m to 296.00 m.

The land environment is described by landuse/landcover of the study area within 10 km radius and soil

environment of the study area within 5 km radius.

3.4.5.2 Land Use Description

Integrated Township



CHAPTER 3


The land use / land cover of the project site was done to identify the land use pattern and land cover

pattern of the study area. The study of land use in the area enables one to know about the land that can

be used for various development activities envisaged in post project scenario. It also enables to envisage

the scenario emerging due to the increase in demand for land with increase in population and the

impacts arising due to the interface with the various project activities.

Objectives of the Study

The objectives of the present study are:

To map the study area with respect to various land use/land cover change over the past 10 years.

To identify the sensitive areas within 10 km radius around the project site.

Methodology

The land use / land cover pattern has been established based on the analysis of the data received from

satellite imagery by making land use/land cover map with the help of GIS technique. References have

been taken from Survey of India. Also the data based on Census of India, 2001 was referred and landuse

study was done within 10 km radius area with limited ground truth verifications. Ground and ancillary

information have been used to identify the sensitive places within 10 km radius of the project.

Land Use Pattern Classification and description

The classification of landuse / landcover pattern of the study area is mainly dominated by the types -

agricultural land, waterbodies, canals, settlements or cultural use,and etc. The agricultural land covers

the majority of the land which is about 79.97% of the study area. The land use data are presented in

Table 3.8 and also highlighted with a pie chart at Figure 3.3. The landuse /landcover map is presented in

Annexure VII.

Soil:

Soil formation is influenced mainly by climate, geology, relief and other biotic interactions. To assess

the soil quality of the proposed area, following stations were selected. Soil profile and quality was

studied at 4 different locations.

The composite soil samples were collected from different location and were analyzed for

characterization., Monitoring maps are attached as Annexure VIII(d) and the results of the monitoring

and analysis is presented in the Table 3.9 (a).

Methodology

The soil samples were collected in the Oct- Dec, 2015 from 5 locations as given in above Table. At each

of these locations 3 sub-locations were identified randomly from where soil was collected from up to 30

cm below the surface. The final 4 samples represent homogenously mixed soil from these 3 sub-

locations for each location. The samples were filled in polythene bags, labeled in the field with number

and site name and sent to laboratory for analysis. Table 3.9(b) gives the idea of the frequency and

methodology of selection of soil sampling stations and monitoring process.

Aquatic Flora of the Buffer Zone

There is no any major aquatic habitat in the buffer zone except some sewage fed small ponds and some

monsoon fed streams. During the present survey some macrophytes were identified nearby the ponds

from the buffer zone were Azolla pinnata, Cyperus sp.,Eichhornia crassipes, Ipomoea aquatica, Lemna minor,

Limnophila indica, Ludwigia sp., Ottelia sp. and Polygonum glabrum.

3.4.6.4. 2 Fauna of the Buffer Zone

The major part of the study area lies under agriculture field and barren land which restrict the wildlife

habitat significantly. There is neither any wildlife sensitive area nor any corridor for the movement of

wildlife is present in the study area. A list of animals of the study area has been prepared on the basis of

local inquiry from the village people and from the available published literatures. The animals thus

recorded were cross checked with Wildlife ProtectionAct (1972) for their schedule.

Mammals

Domesticated mammal species were reported from buffer zone during the field survey. Common grazing

animals like Cow, Goat and Buffalo etc. were noticed in the buffer zone. Inquiry from village people

regarding wild animals reveals that monkey, Indian hare, fruits bat, Wild boar, Indian Fox etc. are often

3.4.6.5. Agricultural land

Chhattisgarh is a state in central India having an area of 135,194 sq. km. Chhattisgarh is a major source

of electricity and steel for India, accounting for 15% of the total steel produced in the country.

Integrated Township



CHAPTER 3


Chhattisgarh is one of the fastest-developing states in India. The state is known for its abundant natural

resources including forest, minerals, rivers and valleys.

In Raipur district, a large numbers of population dependent on agriculture for their economic status.

Also, agriculture is the main occupation of the people living in the buffer zone. Important crops

grown in the area are wheat, rice, chickpea, soybean, lentil, black gram, linseed etc. The area also

produces vegetables like potato, cauliflower, onion, tomato, chilies and fruits like mangoes, guava,

citrus etc.

3.4.6.6. Fishery

Fisheries are an important economic activity in the state (including Raipur district) for additional

employment and income generation. Chhattisgarh is blessed with someRivers, Reservoirs, Dam and

ponds which supported the fish production in the state along with the Raipur district. Few fisherman

communities are involved in fish production and aquaculture practice in Raipur district. Whereas, in the

buffer area of present construction project, perennial water bodies for fisheries point of view are not

present.

3.4.6.7. Occurrence of Schedule-I and Rare, Endangered and Threatened Species (RET)

Overall studies reveal that, Schedule-I species as well as Plant species come under the category of RET

have not been observed from the buffer zone of Integrated Township Development Project. So, there is

no need of conservation plan. However, all care will be taken for protection of others flora & fauna also,

if any in the lease hold area.

3.4.7. SOCIO ECONOMIC IMPACT ASSESSMENT

3.4.7.1 INTRODUCTION

Socio-Economic Impact Assessment (SEIA) refers to the systematic analysis of various social and

economic characteristics of the human beings living in the geographical area/study area around the

proposed project location. SEIA is carried out separately but concurrently with Environment Impact

Assessment (EIA). The study area consists of core and buffer area around the project site. The SEIA

focuses on the likely effects of the project on social and economic well-being of the community. The

impact(s) may be direct or indirect, positive or negative.

Integrated Township



CHAPTER 3


In this section of the EIA Report an attempt has been made to assess the Socio-Economic Impact of the

proposed ‘Integrated Township Project’ at village Banarsi, Ramchandi and Nakti, District Raipur in the

State of Chhattisgarh.

3.4.7.2 OBJECTIVES OF SEIA

The prime objective of the current study is to assess the likely impact of the proposed project on socio-

economic characteristics of people living in the study area. Further, it is to be established whether the

impact would be direct or indirect. Furthermore, it is to be examined whether the said impact would be

positive or negative. Lastly, it is to be comprehended if the impact is positive how long it would sustain

or if it is negative how soon the same could be eased.

3.4.7.3 SCOPE OF THE STUDY

The Scope of the study is as follows:

a) To collect baseline data of the study area.

b) To comprehend socio-economic status of the people of the study area.

c) To assess the probable impact of the project on social & economic aspects in the study area.

d) To evaluate the likely impact of the project on Quality of Life of the people living in the study area.

e) To ensure sustainability of the positive impact.

f) To suggest mitigation measures and agency responsible for taking action in case of adverse impact.

3.4.7.4 METHODOLOGY

For Socio-Economic Impact Assessment of the proposed project, we carried out systematic analysis of

the various socio-economic characteristics, both in terms of quality and quantity. Accordingly, both

qualitative and quantitative data was collected from secondary sources. The secondary data was

collected from the published data/information of the Census Authority. Records of the state and district

administration were also referred to.

For collection of primary data, a sample survey was conducted in the study area. In each selected

habitation, a specified number of representative households were selected scientifically for collection of

Integrated Township



CHAPTER 3


information through face to face interviews with head of the household or any responsible member of

the family.

Census-cum Sample Survey in the Core Area

As the likely impact of the project will be greatest in the core area and it diminishes progressively when

move away from the core area to the periphery of the study area, a Census-cum-Sample Survey was

conducted in the core area for the collection of socio-economic data.

It is treated as a Census Survey because all the habitations located in the core area were surveyed for the

collection of information. Further, in each habitation a household survey was conducted by drawing

representative samples from a list of households prepared. Since, collection of information from all the

households in a habitation is time consuming and expensive, the Sample Survey

approach was adopted for collection of information from the selected households.

Sample Survey in the Buffer Area

In the buffer area, where the impact of the project progressively reduces with the distance from the

project area, two stage sample design was adopted. The first stage units were census village(s) and the

ultimate stage units were households.

Sample Design

Two-Stage Sampling Design was adopted in the study area. The First Stage Units were Census

villages/towns and the Ultimate Stage Units were households in the selected villages/towns.

Sample Size

The sample size at each level (village/town and household) was decided by using the formula = √

{(1.96 *σ)/Δ}; where = Sample size, 1.96 is the Table Value of Confidence Limit, σ = Standard

Deviation and Δ = Degree of Precision.

Selection of First Stage Units (Villages/Towns)

In buffer area the sample villages/towns were selected from the list of Census villages by adopting the

method of Probability Proportional to Size (PPS), the size being number of households in a given

village.

Integrated Township



CHAPTER 3


Selection of Ultimate Stage Units (Households)

The sample households were selected from the list of households by adopting the method of Circular

Systematic Sampling. This method was adopted since the sampling frame i.e. the complete list of

households was readily available.

3.4.7.5 SURVEY INSTRUMENTS

The following Schedules/Questionnaires were developed for collection of primary data from the

households and villages/towns:

Questionnaire for Village/Town Particulars

Questionnaire for Household Details and Project Perception.

Each of these data instruments has segment blocks and there are both open-ended and closed-ended

questions.

3.4.7.10 SOCIO-ECONOMIC IMPACT OF THE PROJECT

Integrated Township



CHAPTER 3


Impact on Demographic Composition

The proposed project will make some change in the demographic composition of the study area as the

additional estimated population of 43,319 including Residential Population, Commercial Population,

Public & semi-public Utilities, Maintenance Staffs and Visitors increase after the completion of the

project. Whereas the people recruited for providing employment will be met locally to the maximum

extent.

Hence, there is possibility of in-migration of people from outside the study area. Accordingly, there will

be some variation in the total population of the study area including that of sex ratio, when the project

completed.

Employment Opportunities

It is estimated that about 150-200 people will get employment due to the project. The proposed project

will provide employment mainly to the local people in the construction phase and during the operational

phase. Indirect employment is also expected due to the associated activities. It is a positive impact of the

project since it will provide employment opportunities to the local people.

Impetus to Trade & Business in Construction Materials

The proposed project will give much impetus to trade & business on construction materials in the

nearest market to the project area. It is expected that trading and business will flourish on various

construction materials namely coarse sand, fine sand, stone aggregate, cement, reinforcement steel,

pipes, bricks, conduit pipes, PVC overhead tanks, glaze & floor tiles, hardware, stainless sinks etc.

Impetus to Infrastructure Development

The project will pave the way for various infrastructure developments that includes roads, parks, play

grounds, schools, hospitals, bus shelters etc. This is a positive impact which will create further

employment opportunities for the local people.

Impact on Agriculture

There will be no negative impact on agriculture as no cultivation is taking place on the proposed area

and the area is likely to be free from annual floods, which destroy standing crops land and property.

Impact on Road Development

Integrated Township



CHAPTER 3


Movement of trucks & tractors and other vehicles to & fro the project site is expected during the

construction period. Hence, there is ample scope for road development in the project area. Adequate

parking space within the project site will be developed for loading & uploading of materials.

There shall also be adequate parking provisions for visitors so as not to disturb the traffic and allow

smooth movement at the site.

Impact on Law & Order

As most of the workers to be employed in the proposed project are local residents no law & order

problem is envisaged. It is expected that the workers will attend to their duties from their residence and

return to their homes after the day’s work. However, to meet any untoward incident one police post may

be set up close to the project site.

Impact on Health

There are no chances of any major diseases due to the construction work.

However, to meet any emergency few safety measures are outlined below:

a) Safe Working Environment: The project proponent shall ensure health & safety of all the

employees at work. All efforts will be made to provide & maintain a safe work environment and

ensure that the machinery and equipments in use are safe for employees. Further, it will be ensured

that working arrangements are not hazardous to employees.

b) Provision of First Aid: In case of any accidents arising out of the proposed construction works,

timely and prompt first aid treatment is, often, the most important tool. Suitable first aid

arrangements shall be made at the site for rendering immediate first aid in case of any injury. The

first-aiders will be well trained in handling patients working in the project.

c) Regular Medical Examination: For all construction workers, medical examination will be made on

regular basis.

d) Health Education: Adequate health education and information related to the work will be provided

to the workers so that their health and safety can be ensured.

e) Tie-up with the Nearest Hospital for Medical Assistance: To meet the medical needs of the

construction workers in case of accidents, tie-up with nearest hospitals will be made. Efforts will be

CHAPTER 3


made to reserve a few beds in the said hospitals for the workers to meet any emergency. This will

ensure timely medical aid to the affected persons.

f) Supply of Mask and Gloves: The workers exposed to dust will be provided with dust masks to

prevent them from getting affected by respiratory diseases. Gloves will be provided to workers

working with hand tools, to ensure safety of their hands.

3.4.7.11 CONCLUSION

Due to the ‘Integrated Township Project’ the infrastructure of the study area may improve by setting up

and development of schools, hospitals & dispensaries, bank & post offices, bus shelters, roads, parks,

play grounds etc. This will give a boost in the quality of life of people of the study area.

The Socio-Economic standard of people living in the study area will improve due to employment

opportunities created due to the project. This will lead to better quality of life and will also set a standard

for future development in the study area.

In the study area, there is large scope of improving basic amenities & social infrastructures facilities. It

is expected that same will improve with operational running of the project and promoting the CSR

activities by the project proponent.

ANTICIPATED ENVIRONMENTAL IMPACTS & MITIGATION

MEASURES

4.1 INTRODUCTION

This chapter discusses identification and appraisal of various environmental impacts due to

Integrated Township Project. Generally, the environmental impacts can be categorized as either

primary or secondary. The development, construction and functional phase of the project

comprise various activities, each of which may have some impact on environmental parameter.

Various impacts during the development, construction and operation phase on the environmental

parameters have been studied to estimate the impact on environment. Integrated Township

Project will be constructed and developed gradually in the time span of 2-3 years (approx.). In

development phase, basic infrastructure facilities like internal road, sewerage system, storm

water drainage, street lighting etc. will be developed.

For proper evaluation and assessment of the environmental impacts due to development,

construction and functional phase of project understanding to the various activities associated

with the Integrated Township Project is essential. Various activities related to the project would

be different, in terms of nature during the development, construction and functional phase.

The impact identification and prediction process aims to:

• Identify potential source or cause of impact through out the life of project.

• Characterize the potential impacts affecting a target or receptor (physical, human and

socio-economic).

• Assess the potential of changing likely-hood of impact through Environmental

Management Plan (EMP).

• Prediction of the impacts due to the development, construction and functional activities

encompass the developmental processes to be undertaken during construction and functional

phases.

For each category of environmental receptor (such as, ambient air quality, water quality, soils,

land, etc.) the potential impacts of activities during development & construction and functional

phases have been identified. Pollution sources & its characteristics, the potential impacts and

magnitude of the impacts have been assessed and discussed in detail in following sub sections.

Integrated Township



CHAPTER 4


In each case, cognizance has been taken to mitigation measures inherited in the development &

construction and functional phase.

4.2 IMPACT MATRIX

Various activities from the Integrated Township project are likely to have some impact on the

environmental constituents during its construction as well as operational phase. The impact

assessment matrix given in Table 4.1 reveals the impact associated with each activity of the

project on various environmental parameters during construction and function phase respectively

before any mitigation measures are implanted. To assess the severity of the impacts, they are

categorized as follows:

4.5 ASSESSMENT OF ENVIRONMENTAL IMPACTS DURING DEVELOPMENT

AND CONSTRUCTION PHASE

4.5.1 Topography

Impact: Topography around the project is almost plain. Therefore, topography and

physiography of the area will not be affected during the construction and post construction phase

of the project. Hence, no significant impact is anticipated on the topography and physiographic

from project by M/s DBH Township LLP.

It is further proposed to maintain 10 % of the total area as green through plantation of various

local and aesthetic species to improve the vegetation covers of the area.

Mitigation Measure: Since there is no significant impact on topography from the project, no

detailed mitigation measures are proposed. It is however proposed that apart from the proposed

plantation greens, turfing with local species will be carried out extensively.

Integrated Township



CHAPTER 4


4.5.2 Land Use Pattern

Impact: Integrated Township Project will be developed as per Land Use Permissibility of Layer

II of Naya Raipur Development Plan which demarcates the project site as residential zone.

Hence, no significant impact is expected from the project which will be constructed after

obtaining all necessary permissions.

4.5.3 Land Environment

Impact: At Integrated Township Project, soil would be excavated at project site for foundations

of residential, commercial and other purposes. During the disposal of redundant overburden, soil

of filling area would be covered and lost permanently.

The soil excavated during construction will be first temporarily stored in an area earmarked and

then shall be used to fill up low lying area in and around the project site and rest of the soil shall

be transported by road to fill up low lying areas elsewhere. Proper drainage system shall be

provided to deal with the storm water in case of rain. The impact on soil during construction

phase will be marginal and reversible in the nature.

Mitigation: It is proposed to remove vegetative cover only from the specific site on which

construction is to take place and allowing minimal disturbance to the vegetation in adjacent

areas. Land clearing activities only confined to necessary areas. The top soil will be stripped

from constructional areas and stockpiled for later reuse in landscaping. The number, frequency

and area of movement of heavy machinery will also be restricted.

4.5.4 Water Environment

4.5.4.1 Ground water Quality

Impact: No hazardous chemical and material will be used in the development and construction

phase of Integrated Township project. Debris and wastes generated during this phase will be

collected and disposed suitably. Therefore, possibility of contamination of ground water will be

negligible. Hence, no impact is anticipated on the ground water quality during the construction

phase.

Integrated Township



CHAPTER 4


Mitigation: A well planned solid waste management plan will be followed during the

construction phase including timely collection, segregation and disposal as per legal

requirements.

4.5.4.2 Ground Water Hydrology

Ground Water Hydrology

Impact: In the area around the Integrated Township project, rich aquifers are present. Water

requirement during construction phase will vary depending upon construction activities and will

be met from Canal water. Water will be required for site preparation activities dust settlement,

consolidation, compaction and curing as well as building construction and drinking water

requirement. The requirement of construction water will not put sudden pressure on the available

ground water recourses of area. Therefore, impact on ground water resources will be

insignificant during construction of project.

Mitigation Measures: Although no significant impact is anticipated on the groundwater regime,

it is proposed to carry out the following to further minimize the demand on freshwater resources:

• Curing water will be sprayed on concrete structures and free flow of water not allowed.

• After liberal curing on the first day, all concrete structures will be painted with curing

chemical to save water to stop daily water curing hence save water.

• Concrete structures will be covered with thick cloth/gunny bags and then water sprayed

on them to avoid water rebound and ensure sustained and complete curing.

• Ponds will be made using cement and sand mortar to avoid water flowing away from the

flat surface while curing.

• Water ponding will be done on all sunken slabs. This will also highlight the importance

of having an impervious formwork.


Emissions Source: The potential sources of air emissions during the construction and

development phase of the project will be as follows:

• Dust from earth works (during site clearance and preparation);

• Emissions from the operation of construction equipment and machines;

Integrated Township



CHAPTER 4


• emissions from vehicles running to site;

• emissions during the unloading of material at the site;

• emissions during mixing of cement with other building materials during development and

construction activities;

• Air emissions other than dust arise from combustion of hydrocarbons. The pollutants of

concerns are NO2, SO2, CO, particulate etc.

Potential Impacts: Ambient air quality effects are normally assessed in relation to their

potential to cause;

• Health deterioration and nuisance in local communities

• Health deterioration amongst onsite workers

Assessment of the impacts from Dust Emissions: During the excavation of channels,

foundations, unloading of construction material, cement bags and mixing of cement with other

building materials such as brick and silica dust, wood dust, fugitive dust emissions may be

emitted at construction site. During construction, curtaining floors from all sides will be done to

prevent cement dust from becoming airborne. It may be noted that all the emissions will be in the

form of coarse particulate matter and settle down ultimately in closed vicinity of construction

site. Therefore, no significant impact is anticipated due to dust emission during development and

construction phase.

4.5.6 Noise Environment

During the construction phase of project, noise will be generated from the various sources. Some

major sources of noise generation at project site are listed here under:

• Generation of noise during movement of vehicles carrying materials and loading &

unloading activities.

• Generation of noise from excavation machines, concrete mixer and other construction

machines,

• Generation of noise during concreting, hammering, etc.

Integrated Township



CHAPTER 4


All the above-mentioned sources of development and construction activities at Integrated

Township project would be intermittent and experienced occasionally. It may also be noted that

the most of the construction activities would be carried out only during the daytime.

The expected noise levels from various activities are given hereunder:

From vehicles bringing materials to the site 70 dB (A)

Excavation 80 dB (A)

Concrete Mixtures 80 dB (A)

Hammering 85 dB (A)

Resultant Noise Level:

The combined effect of above sources can be determined as per the following equation:

Lp (total) = 10 log (10(Lpl/10) + 10(Lp2/10) + 10(Lp3/10) +……..) ……. (1)

Where: Lp1, Lp2 and Lp3 are noise pressure level at a point due to different sources in dB (A). The

resultant maximum noise level for the above sources as calculated using equation (1) is 89.3 dB

(A).

For an approximate estimation of dispersion of noise in the ambient air from the sources point, a

standard mathematical model for sound wave propagation is used. The sound level generated by

noise source decrease with increasing distance from the source due to wave divergence. An

additional decrease in sound pressure level from the source is expected due to atmospheric effect

or its interaction with objects in the transmission path.

For hemispherical sound wave propagation through homogenous loss of free medium, noise

levels at various locations can be calculated due to different sources using model based on the

first principles as per the following, equation:

Lp2 = Lp1 -20 log (r2) – 8 ………. ( 2 )

Where: Lp2 and Lp1 – Sound Pressure Level (SPLs) at points located at sources and at distance

of r2 from the source respectively in dB (A).

Assuming no environmental attenuation factors, noise modeling has been done, which shows

that noise level will be mingle with baseline noise level with in short distance of 200 m as the

difference between background (56.8) and the projected noise level will be 10.6. Noise modeling

results for construction phase have been given in Table 4.4.

Integrated Township



CHAPTER 4


Table 4.4: Noise Levels

The noise produced during, development and construction phase will have temporary impacts on

the existing, ambient noise levels at project site Therefore, the impact of noise levels on

surrounding area will be insignificant during the development and construction phase.

Mitigation: To minimize impacts of noise generation from construction activities, the workers

will be provided with ear muffs and other protection devices.

4.5.7 Terrestrial Ecology

Impact: There is no loss of forestland due to the construction of the Integrated Township

project. No tree felling is involved, as the site is devoid of vegetation.

Birds and other domesticated biodiversity observed near the project site are common and already

adapted to thrive in human - colonized habitats. The project will not have any major negative

ecological impact. There is no forest near the project site and therefore there will be no effect on

the ecology of the area.

Mitigation Measures: However, it is to develop extensive green areas in the project site to

improve the aesthetics of the area which will also help in reduction of air pollution, noise

pollution and provide suitable habitat for local birds and animal species.

4.5.8 Economic Impacts

Impact: Relatively long-lived economic impacts of the development and construction phase are

likely to be experienced in local area for the duration of construction phase of 2 years as workers

make everyday purchases from local traders in near by areas. This is likely to give a short-lived

stimulus to the traders that may disappear as soon as the construction is complete. Noticeable,

flow-on economic impacts will be experienced in other sectors of economy as a result of

purchase of construction materials and the payment of wages and salaries to the personnel

engaged in the development and construction of colony. Once the development and construction

of residential project will complete, there will be some long-term positive impact on the

economic structure of the area. People in the area will get direct and indirect employment

opportunities and other benefits from the residents of the Integrated Township Project.

Therefore, overall positive impact is anticipated on economy of the area due to development and

construction activity of the Integrated Township Project.

4.5.9 Socio-Economic

During the development and construction of Integrated Township Project, about 300 to 400

skilled and semiskilled and unskilled workers per day will get direct employment opportunity,

which will have beneficial impact on the local people and improve socio-economic conditions of

the area.

4.5.10 Construction Camp

Impact: During the development and construction phase, most of the laborers will be from local

areas as Integrated Township Project will be developed gradually in the time span of about 5

years. Therefore, laborer camps will be constructed to accommodate the laborers at the project

site. This may lead to sanitation problems in the absence of adequate facilities.

Mitigation: Suitable measures will be taken at the construction camps to mitigate anticipated

impacts due to temporary accommodation of laborers such as provision of clean drinking water,

adequate toilet facilities, water and solid waste disposal system.

Other safety precautions to be maintained at work site including provision of PPEs, guarding of

dangerous machine parts, maintenance of equipments as hoists and lifts etc, and adequate

provision of different types of fire extinguishers will be made. All applicable rules and

regulations pertaining to workplace health and welfare of workers will be adhered to.

4.5.11 Solid Waste Management

Impact: The construction and demolition waste includes debris, concrete (often recycled and

reused at the site), steel and other metals, pallets, packaging and paper products, fluorescent

tubes, wood beams, joists, studs, baseboards, cabinets and cupboards, railings, brick, doors and

casings, interior windows, bathroom fixtures, light fixtures, ceiling grid and tile, furnishings,

Integrated Township



CHAPTER 4


replant trees, shrubs. All wastes generated during the construction phase shall be collected and

segregated for disposal as per the standard practice.

During the development and construction phase, some amount of debris, cuttings of construction

materials may be observed at construction site. However, the quantity of these waste materials

would be very small and limited up to the construction site only. There will be no contamination

due to this waste as it will be collected time to time during construction phase and disposed

accordingly.

Mitigation Measures: After due waste segregation, recyclable wastes will be sold off to scrap

dealers and vendors, while inert wastes will be disposed off in landfills. Hazardous wastes will

be disposed off as per the provisions of the Hazardous Wastes (Management & Handling Rules,

1989).

4.5.12 Transport Linkage and Traffic

Impact: During development and construction phase, construction labour and construction

materials bringing vehicles will approach the project site. The residential colony is well

connected to neighborhood, where public transport facility, like, buses and minibuses are easily

available in the area as transport linkage. During construction phase, some impact is anticipated

on the transport linkage of the area, however increase in traffic will not adversely affect the local

traffic pattern since the site is well connected by broad road and present traffic load on these road

are not significant.

Mitigation: Through careful planning, the movement of the heavy vehicles will be scheduled to

reduce load on existing traffic such that the peak hours are avoided. It shall also be ensured that

all the vehicles to the site will be provided with Parking space such that there is no waiting time

along the access roads.

Integrated Township



CHAPTER 4


4.6 ASSESSMENT OF THE ENVIRONMENTAL IMPACTS DURING OPERATION

PHASE


Impact: During the operation phase of the project, the soil may get polluted/ contaminated from

littering of various kinds of wastes generated within the site such as food items, paper, wood

pieces, paints, pesticides, oil & grease etc. However, owing to the proposed solid waste

management system, no significant impact is anticipated.

Mitigation Measures: To ensure against any chances of soil pollution, it is imperative to

establish a well planned solid waste collection system covering all areas of the project site apart

from door to door for the residential units. An identified area shall be designated for storage and

segregation of the wastes which will be treated/ disposed as per their characteristics.

4.6.2 Water environment

4.6.2.1 Ground water hydrology

Impact: During post construction phase, the total water requirement of the Integrated Township

Project is approx. 4,752 KLD, out of which total domestic water requirement is 3,986 KLD, say

4.0 MLD. The fresh water requirement is approx. 2,790 KLD which is 70% of the domestic

water demand. The water supply will be from Canal Water. Therefore, no significant impact is

anticipated on ground water resources due to project.

Mitigation Measures: The rainwater harvesting will recharge groundwater aquifers from the

open areas. Treated wastewater from the site will be recycled for landscaping and flushing to

further reduce demand on freshwater resources.

Water meters conforming to ISO standards should be installed at the inlet point of water uptake

and at the discharge point to monitor the daily water consumption. To further lower the water

consumption, options of Low flow flushing systems, sensor based fixtures, waterless urinals, and

tap aerators etc will be explored.

4.6.2.2 Ground Water Quality

Impact: The storm water from the site will be used for recharging groundwater resources after

adequate treatment of the storm water through oil, grease traps and filtration. The wastewater

Integrated Township



CHAPTER 4


from the site is proposed to be used for landscaping only after adequate treatment in Sewage

Treatment plant. Hence, no adverse impact is anticipated on the groundwater quality form the

project.

Mitigation Measures: The Integrated Township Project will be well maintained. Solid waste

management practices will be adopted and followed to prevent groundwater pollution through

leaching.


Impact: During the post construction phase, cars, scooter/motorcycle will be owned by the

population of Integrated Township Project. Vehicular emissions will be major source of air

pollution. Quantum and dispersion of pollutants form vehicular emission will depend upon the

following:

• Emission of pollutants from additional traffic on the roads due to the projects,

• Meteorological conditions.

From vehicular emissions, PM, NO2, SO2 and CO is pollutants of primary concern released from

traffic movement. The dispersion of vehicular emissions would be confined within 300 m from

the road and from the line source model it is observed that concentration will decrease with the

increase in distance from road. It is anticipated that the contribution of vehicular emissions in

ambient air quality will be marginal but well within the stipulated National Ambient.

There is provision of 4 no. of DG sets of total 1, 270 kVA (1 X 320 kVA + 1 X 625 kVA + 1 X

125 kVA + 1 X 200 kVA) capacity for power back up in the Township Project only for Public

Utilities and External Lighting. The DG sets will be equipped with acoustic enclosure to

minimize noise generation and adequate stack height for proper dispersion. Multistoried Group

Housings, Commercial Building, Institutional Buildings etc. will have their own standby supply

arrangement.

Mitigation Measures: In the Integrated Township Project, green belt will be developed inside

the premises of the project site and along the internal road, which will work as barrier for the

movement of pollutants and help in pollution control.

Model details and Frame work of Computation:

The predictions for air quality during operation phase were carried using CPCB/MoEF approved

“USEPA, Industrial Source Complex (Version - ISCST3)” Dispersion model developed by the

US Environmental Protection Agency (USEPA) for prediction of pollutants dispersion from

single or multiple point sources using emission and hourly meteorological data of the study

period. Assumption used in the model was as follows:

• The plume rise is limited to that of the mixing layer as published by IMD in the

Catalogue of Atlas of Mixing Heights in India for the site

• Stack down-wash is not considered.

• Flat terrain is used for computations;

Integrated Township



CHAPTER 4


• It is assumed that the pollutants do not undergo any physico-chemical transformation.

• Chemical and scavenging process occurred in the atmosphere in the pollutants released at

the stack exit is not considered.

• Prediction is based on single/multiplepoint sources, pollution released at stack exit and

dispersed on the ground under influence of local meteorological conditions during the season.

ISCST3 dispersion model was used to predict GLC caused by a single point source (4 stacks) at

each receptor of 40 m x 40 m of grid network covering total area of 2000 m x 2000m around the

proposed source with stack & emission values and 1-hourly meteorological data. It was

observed that SO2, NO2, Co and PM were significant pollutants released from the fuel of the

D.G. sets. Emission of PM, CO and SO2 were found insignificant with low values compared to

NO2. In this project, NO2 was the worst affected pollutant released into the atmosphere (Table

4.5) with high emission value.

Spatial distribution of NO2 is shown in Isopleth Figure 4.2. It was observed that GLC closed to

the proposed source will be not significant. 24-h maximum incremental GLC was 6.90 µg/m3

occurred at the distance 707.10 m, NE of the project site.

Conclusion

Maximum Incremental GLC of NO2 is 6.90 µg/m3 due to DG sets in the Integrated Township

project. High to moderate wind speed and minimum stack height of 30 m facilitates dispersion at

the distance of 707.10 m NE under the influence of local meteorology. Low GLC of pollutants

was predicted due to high Stack height of 30 m fitted with DG sets. Predicted GLC of all

pollutants are given in Table 4.7 as below:

distance of 707.10 m, NE under the influence of local meteorology.

Mitigation Measures: The project proponent will develop a green belt inside the premises of the

project site and along the internal road, which will work as barrier for the movement of

pollutants and help in pollution control.

Integrated Township



CHAPTER 4



Impact: The main sources of noise from the project are running of D.G. Sets and vehicular

traffic. D.G. Sets will provide emergency electricity supply during power failure. This will be

intermittent and for short durations. The vehicles playing within the site will be mainly of the

residents and are hence not expected to cause unnecessary noise. Hence, during this phase, no

major impact on noise environment is anticipated.

Mitigation Measures: D.G. Sets will be fitted in acoustic enclosures to control the noise

generated within 25 dB (A) insertion loss or for meeting the ambient noise standard whichever is

on higher side as per E (P) Act, GSR 371 (E) and its amendments. Adequate personnel protective

equipment (PPE) will be provided. The traffic noise will diminish within a short distance from

the source of origin. Honking within the site will be discouraged. Proposed rows of plantation

will further restrict the noise on other side of the plantation i.e. outside the boundary.

4.6.5 Terrestrial Ecology

Impact: The project proposes 91,860 m2 of green area (10% of net planned area, excluding EWS

area) that will be planted with local species with aesthetic appeal that will attract local bird and

insect species. As against the existing barren stretch of land, the project will add to the greenery

and beauty of the region.

Mitigation Measures: Various kinds of plantation such as curtain, avenue and ornamental

plantation and lawns will be started during the construction phase itself and maintained during

the operation phase. Open space and Parks will be fenced through the grasses and ornamental

plants. Local and low water demanding plants that will also be effective as sinks for various

pollutants and attract birds will be grown in the site that will contribute in positive to the local

ecology.

4.6.6 Socio-economic Impact

Impact: During operational phase of Integrated Township Project, more than 200 persons will

get employment opportunities as staff for management, maintenance and security. As an

Integrated Township



CHAPTER 4


estimate, during post construction phase, more than 400 persons will get marginal employment

opportunities from the residents of Integrated Township Project who would work as domestic

helpers. This will help in improving the quality of life of economically weaker sections of the

local area.

Mitigation Measures: To further improve the socio-economic conditions of the area, it may be

proposed to employ mainly local people as workers. Much of the maintenance arrangements may

also be made with local companies and purchase of new parts from the local market.

4.6.7 Transport Linkage and Traffic

Impact: The vehicle from the project will increase car and two wheeler traffic load along the

road during peak hours. However, since present load is lean, increase in traffic load may not lead

to traffic congestion problem.

Mitigation Measures: As per the conceptual plan, the entrance to the project site is proposed

along the road. The available width provided shall have sufficient merging space for the vehicles

while meeting the road.

4.6.8 Energy Resources

Impact: During the operation phase of the project, electric supply will be provided from

Chhattisgarh State Power Distribution Company Limited. The proponents will make

arrangements for meeting any electricity shortage for the project. Therefore, energy resources of

the region will not be affected significantly.

Mitigation Measures: To promote energy conservation, it is proposed to provide the buildings

with low energy consuming fixtures maximize availability of natural light.

CHAPTER-5

ANALYSIS OF ALTERNATIVES

5.1 INTRODUCTION

This chapter discusses the assessment of various options that may be available for different

components of the project in terms of environmental suitability. Lately, there are a number of

options available for the use of building materials, means of energy conservation and methods of

transportation. The various applicable options are thus evaluated for their suitability to project

and environment.

5.2 BUILDING MATERIALS

The choice of building materials plays an important role in terms of energy efficiency of the

building. The manufacturing of building materials should also be assessed to ensure the use of

environment friendly and recycled/recyclable construction materials.

5.2.1 Wall

Conventionally, sun burnt clay bricks are cemented in the construction of walls. The strength of

these construction materials cannot be compromised which will otherwise pose a threat to the life

and property of the occupants. However, presently, materials with similar properties are easily

available that are made of waste products, thereby reducing the waste burden and conserving

natural resources. Thus, the project proposes the use of the following for walls:

Brick and block products with waste and recycled contents such as fly ash (15 to 35%),

blast furnace slag (20 to 25%), sewage sludge, waste wood fibre etc.

Fly ash based lightweight aerated concrete blocks (CLC blocks) – flyash being a waste

product of thermal power plant poses the challenge of disposal. Hazardous in powder

form, it is rendered harmless when moulded as bricks. Fly ash-based lightweight aerated

concrete blocks are manufactured for walling and roofing purposes by mixing fly ash,

quick lime, or cement and gypsum with a foaming agent like aluminium powder

Fal-G products – are manufactured by use of two waste products being fly ash, calcined

gypsum (a byproduct of phosphogypsum or natural gypsum) along with lime.

Perforated bricks

Integrated Township



CHAPTER 5


Materials proposed for use in the wall openings such as doors and windows include:

Precast thin lintels, use of ferrocement-sunshade cum lintel etc.

Renewable timber

Steel manufactured from recycled content

Aluminum manufactured from verified recycled content

Saw dust based doors and window frames

Ferrocement shutters, PVC doors and windows, Rice husk boards, Natural fibre-

reinforced

Polymer composite door panels

The finishing for the openings will be by the use of Fly ash, Ceramic tiles, Terrazzo

floors.

5.2.2 Roof

The conventional material used for roofing is RCC, as it is suitable for longer spans. The

constituents of RCC, i.e. cement, sand, aggregate and steel are energy intensive materials and

high embodied energy content.

Alternately, it is proposed to use lightweight synthetic aggregates such as fly ash based

aggregates, which is suitable for manufacture of brick, blocks, and is good substitute for clinker

and natural aggregates. When pre-cast/aerated cellular concrete walling blocks and roofing slabs

are used in multistoried structures, they reduce the weight, resulting in a more economical

design. They have high rating to fire resistance and provide better insulation and thus improved

energy efficiency. These are manufactured by the aerated cellular concrete manufacturing

process.

5.2.3 Superstructure

Structural frame of building comprises of footing, columns, beams and lintels, over which the

envelope of building is supported. A variety of metals are used in buildings, but the major

building material used structurally is steel. Steel has a high-embodied energy and recyclable

content, as well as scrap value. Aluminum forms the second most common material used for

Integrated Township



CHAPTER 5


roofing sheets, window frames, and cladding systems, which has the highest recyclable content.

Hence, bulk of the metal needs for the building shall be met by steel and aluminum.

Problem with RCC. The choice of cement will be:

Use of fly ash and/or blast furnace slag concrete: The amount of cement used in

concrete can be reduced by replacing a portion of the cement with coal fly ash (waste

material from coal burning power plants) and/or GGBF (ground granulated blast furnace)

slag in conventional mixes.

Recycled aggregates: Recycled aggregates include crushed concrete, brick, glass, or

other masonry waste can also be used in conventional mixes

Lightweight concrete:Aluminum powder when added to lime reacts and form hydrogen

bubbles, and a lightweight cementitious material is formed which could be used in

conventional mixes.

5.2.4 Roads and open spaces

Roads and open spaces consist of compound walls, grills, roads, sidewalks, parking lots, drains,

curbs, landscaped areas, street furniture, tree covers, and flowerbeds.

In line with environment friendly design it is proposed to provide:

Permeable paving- Permeable (porous) paving will be provided to control surface water

runoff by allowing storm water to infiltrate the soil and return to the ground water. The

traffic areas will however continue to be impermeable.

Gravel/crusher fines- Loose aggregate materials from masonry wastes will be used to

cover pedestrian surfaces.

Use of grass pavers on the road, parking and pedestrian areas to reduce the heat island

effect.

Use of steel in fencing, grills, tree covers, and benches and even in streetlights will be

replaced by bamboo in the parks and green landscaped areas.

Integrated Township



CHAPTER 5


5.3 NATURAL HAZARD PRONE AREAS

The project will be situated in low earthquake risk area (Seismic zone- II). Special attention is

thus given to the structural design of foundation, elements of masonry, timber, plain concrete,

reinforced concrete, pre-stressed concrete, and structural steel. All applicable guidelines will also

be followed in this regard to ensure safety of the building and its residents.

5.4 ENVIRONMENT FRIENDLY DEVELOPMENT

Without compromising on the safety and comfort of the occupants, care will be taken to achieve

an energy efficient, water conscious project the benefits of which will be enjoyed in monetary

terms by the residents and other intangible benefits will result for the society at large. This will

be achieved by:

a. Minimal disturbance to landscapes and site condition

The project aims to integrate the new development with the local existing surroundings. Efforts

are made to minimize on-site tree cutting by careful and detailed layout planning. Tree felling

shall be undertaken only after receiving requisite permissions and under strict supervision. The

original landscape of the site has also been integrated with the design of the plotted residential

such that there is no alteration the site topography.

b. Resource Conservation and Environmental Friendly Building Materials

To reduce the ecological footprint of the development, use of recycled material for construction

and conserving natural resources is of primary importance. In this light, the use of recyclable

building materials has been proposed for various building materials. It is also proposed to reuse

building components, minimization of construction wastes etc.

The project is also committed towards conservation of water. This includes use of treated

sullage, rainwater harvesting, provision of low water flow fixtures and raising awareness on

means of water conservation.

c. Efficient use of Water and Water Recycling

The need for water conservation in the face of impending water crisis cannot be overemphasized.

The project will follow a three pronged management for water resource viz water resource

development, minimize use of water and recycle sullage generated within the site.

Integrated Township



CHAPTER 5


Rainwater harvesting across the entire project area is proposed to recharge groundwater. A

detailed storm water drainage system and water harvesting procedures are proposed to achieve

this.

The water demand is proposed to be brought down by the use of water efficient fixtures,

implement best management practices for water in both the Integrated Township Project and

horticultural activities. An important means for achieving this is spreading awareness to the

occupants for generating water conservation awareness.

To reduce the freshwater demand of the project, sullage from site will be treated in a STP and

recycled for landscaping and flushing.

d. Use of Energy Efficient design and Eco-Friendly Equipment

The project will be designed such that there is optimal solar energy utilization, especially for

natural light availability. Shading will be provided on sides that will otherwise reduce the energy

efficiency of the building. Energy conservation will be one of the focuses during the planning,

development, construction and post construction stages.

e. Use of Renewable Energy

The electrical supply is largely dependent on thermal power plants that are largely responsible

for accelerating the phenomenon of global warming and consumption of limited natural

resources. It is of paramount importance to shift focus on other renewable sources of energy to

achieve sustainable development in the energy sector. The project area in Raipur receives

adequate hours and intensity of sunlight for effective solar energy generation. Taking full

cognizance of the availability of natural sunlight and technology, the project proposes the use of

solar energy to reduce the power demand of the project.

Solar energy will be used for the purpose of heating of the water.

f. Indoor Air Quality for Human Safety and Comfort

To provide the occupants with a safe building is the primary responsibility of a developer. Indoor

pollution sources that release gases or particles into the air are the primary cause of indoor air

Integrated Township



CHAPTER 5


quality problems in homes. Inadequate ventilation can increase indoor pollutant levels by not

bringing in enough outdoor air to dilute emissions from indoor sources and by not carrying

indoor air pollutants out of the home. High temperature and humidity levels can also increase

concentrations of some pollutants. Likewise, it is proposed to use all user safe building materials

such as:

i. The buildings will be painted with low VOC, ammonia free paints.

ii. Asbestos will not be used.

iii. Adequate ventilation will be provided in each residential unit and floor.

iv. Adequate openings for sunlight to enter the building, thereby reducing chances of

microbial growth.

v. All building maintenance and cleaning materials will be kept in an isolated and well

ventilated room with restricted entry.

g. Effective Controls and Management Systems

It is proposed to establish a Management System that will comprise modern equipment’s as well

as an efficient team of maintenance staff.

i. Each tower as well as common area will be provided with fire alarm as well as water

sprinklers.

ii. A security system for the entire plotted residential will be provided comprising intercom

facility, closed circuit camera to the entrance and round-the-clock manning.

iii. Separate entries and exits of residents from the guests are proposed. The staffs’ vehicles

will be provided with identification stickers while visitors’ vehicles will be monitored

through security guards at the entrances.

The project further proposes extensive green areas as avenues, parks and roadside plantations.

The plants not only serve various direct environmental facilities, but also have indirect positive

environmental impacts such as reduction in overall energy use in buildings. The balcony garden

is a natural development of the balcony’s role as a link between interior and exterior

environments. Efforts will be made to cover walls with climbers, as feasible.

Integrated Township



CHAPTER 5


5.5 COMMUNITY ISSUES

Apart from the site occupants, all efforts will be made to ensure that the existing neighborhood is

not adversely affected by the project.

While, the site will not act as a thoroughfare for vehicles, there shall be no restriction to

movement of on-foot visitors and cyclists.

5.6 ENERGY CONSERVATION

To achieve conservation of energy, appropriate design of a building is of paramount importance.

Accordingly, it is proposed to incorporate the guidelines of Energy conservation Building Code,

2005 for the structures of the Integrated Township project.

The concept of passive solar design emphasizes architectural design approaches that minimize

building energy consumption by integrating conventional energy-efficient devices, such as

mechanical and electrical pumps, fans, lighting fixtures, and other equipment, with passive

design elements, such as building citing, an efficient envelope, appropriate amounts of

fenestration, increased day lighting design, and thermal mass. The basic idea of passive solar

design is to allow daylight, heat, and airflow into a building only when beneficial.

The project layout has been finalized after careful citing consideration of various plotted

residential components to optimize availability of natural sunlight. Advanced Solar Passive

Techniques are employed to achieve energy efficiency.

Glazed windows are located to receive maximum sunlight in winter. To reduce

heat losses during the night these windows are often double-glazed and have

insulating curtains.

Thermal storage wall is placed between the glazing and habitable space to prevent

solar radiation from directly entering the living space.

Passive cooling systems i.e. cooling directly from evaporation, convection

radiation without using any intermediate electrical devices.

Provisions for use of desert cooler (Indirect evaporative cooling which comprises

water, evaporative pads, a fan and a pump).

Integrated Township



CHAPTER 5


Effective measures have been incorporated to minimize the energy consumption in following

manners:

• Use of CFL lamps instead of GLS lamps for Flats.

• Use of CFL lamps instead of GLS lamps for Common area.

• T5 lamps are used instead of Normal Fluorescent lamps in Basements

• Using electronic ballast for Discharge Lamps.

• Solar water heating systems shall be provided as per HAREDA norms.

5.7 TRANSPORTATION

A well planned road network is proposed within the project premises. Adequate parking will be

provided during construction phase to ensure that all heavy vehicles visiting the site are provided

parking space within the site. There shall be no parking on the access roads. The movement of

the vehicles will also be scheduled such that the peak hours are avoided.

In the operation phase, entry and exits will be from separate gates to minimize disturbance to the

approach roads to the project site. To avoid congestion of the approach roads, space will be

provided for vehicles waiting checking. Adequate parking is also proposed to ensure there is no

parking along the roads. Within the site, adequate wide roads are proposed. To achieve the same,

speed humps will be provided.

ADDITIONAL STUDIES

7.1 INTRODUCTION

This chapter broadly looks at various aspects related to disaster management, resource

conservation.

7.2 RISK ASSESSMENT AND DISASTER MANAGEMENT PLAN

Integrated Township project encompasses the lives of a large number of people. It also

involves installation of various structures and machineries that meet the comfort and needs

of its population but may also pose serious threat to the occupants in case of an accident. It

is thus considered necessary to carry out a risk assessment and disaster management plan

for the project.

7.2.1 Risk Hazard & its control measures

It is attempted to plan and construct the buildings following all safety norms. However, it is

not always possible to totally eliminate such eventualities and random failures of

equipment or human errors. An essential part of major hazard control has therefore, to be

concerned with mitigating the effects of such emergency and restoration of normalcy at the

earliest. A detailed table showing activities during construction and operation phase along

with mitigation measures are given in Table 7.1

7.2.2 Emergency Response Plan (ERP)

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. Effect the rescue and medical treatment of casualties;

Integrated Township



CHAPTER 7


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.

7.3 RESPONSE IN CASE OF EARTHQUAKE

7.3.1 Response Procedures for Occupants

scene of incident. Any injured persons should be evacuated on priority to the dispensary or one

of the nearest hospitals based on their condition.

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

doorclosed.

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 group housing

buildings will also be provided with automatic fire detection and alarm system.

7.6 RESOURCE CONSERVATION

The project will lead to utilization of various natural resources. As an environmentally

responsible corporate, the developers endeavor to conserve these resources by judicious

management and recycling and strive to build up these resources where possible.

Water Resources: The project will use water from onsite borewell and pond during construction

phase and operation phase of the project. Given the national water scenario, where availability if

Integrated Township



CHAPTER 7


fresh water is fast dwindling, judicious use of the same cannot be over emphasized. Following

means are proposed to be adopted for conservation of this life sustaining resource:

Limited withdrawal of groundwater: There will be no use of groundwater both during

construction and operational phase of the project. The construction and operation phase will

make use of canal water supply.

Reduced use of water: To further minimize the use of available freshwater, various low flow

fixtures may be provided such as Low flow flushing systems, sensor based fixtures, waterless

urinals, tap aerators. Awareness will also be spread amongst the residents on the following lines:

Timely detection and repair of all leakages;

Turning off tap while brushing teeth;

Use of mug rather than running water for shaving;

Avoiding/minimizing use of shower/bath tub in bathroom;

Turning off faucets while soaping and rinsing clothes;

Using automatic washing machine only when it is fully loaded;

Avoiding use of running water while hand-washing;

Avoiding use of running water for releasing ice tray ahead of time from freezer;

Turning off the main valve of water while going outdoor;

Avoiding use of hose for washing floors; Use of broom may be preferred;

Watering of lawn or garden during the coolest part of the day (early morning or

late evening, hours) when temperature and wind speed are lowest. This reduces

losses due to evaporation.

Planting of native and/or drought tolerant grasses, ground covers, shrubs and

trees. Once fully grown, they need not to be watered frequently.

Avoiding over watering of lawns. Good rains eliminate the need for watering for

more than a week.

Setting sprinklers to water the lawn or garden only, not the street or sidewalk;

Integrated Township



CHAPTER 7


Avoiding installation or use of ornamental water features unless they recycle the

water and avoiding running them during drought or hot weather;

Installation of high-pressure, low-volume nozzles on spray washers;

Replacement of high-volume hoses with high-pressure, low-volume cleaning

systems;

Equipping spring loaded shutoff nozzles on hoses;

Installation of float-controlled valve on the make-up line, closing filling line

during operation, provision of surge tanks for each system avoid overflow;

Washing vehicles less often, or using commercial car wash that recycles water;

Treatment and Recycling: The sullage generated from the sites will be treated in an on-

site Sewage Treatment Plant. This will enable the treated sullage to be used for flushing

and landscaping thereby reducing the requirement of freshwater for these purposes.

Rainwater harvesting: The increased hard surface of plotted residential increases the

runoff as compared to the otherwise barren land. It is proposed to harvest this rainwater

runoff that will recharge the groundwater resource while reducing the burden of storm

water management of the city and eventually natural water bodies. Apart from the open

spaces, it is proposed to harvest the roof top rainwater. The storm water will be treated

through an oil and grease trap and allowed to flow through layers of sand and gravel for

filtration prior to reaching the water table, to avoid any possibility of groundwater

contamination.

Construction materials: As a large construction, the project will require various kinds of

natural construction materials such as sand, gravel etc. It is proposed for prior estimation of

required quantities of these materials and procurement only as per requirement. This will

also result in cost-efficiency. Excavated soil from the project site will be used within the

site to the extent feasible. Excess soil will be made available to the construction sites, as

per need.

Energy: To conserve the energy resources, good practices will be followed during the

construction phase such as turning off lights and equipments when not in use, ensuring fuel

Integrated Township



CHAPTER 7


efficiency of motors and vehicles through proper maintenance and minimal work at night.

The principles of energy conservation will also be embedded in the buildings through use

of energy efficient fixtures, maximum availability of natural light and use of solar energy

for street lighting.

7.7 RESETTLEMENT AND REHABILITATION

The project will not result in displacement of any local population and hence, does not

require a resettlement and rehabilitation study.

CHAPTER-9

ENVIRONMENTAL MANAGEMENT PLAN

9.1 INTRODUCTION

Identification and prediction of impacts further needs to suggest the mitigative measures which

would play a vital role in prevention of environmental degradation during construction and

operational phase of the Integrated Township Project. This leads to preparation of Environmental

Management Plan (EMP), therefore EMP forms an imperative part of EIA process.

The Environmental Management plan is a site specific plan developed to ensure that the project

is implemented in an environmentally sustainable manner where all contractors and

subcontractors, including consultants if any, understand the potential environmental risks arising

from the project and take appropriate actions to minimize those risks. EMP also ensures that the

project implementation is carried out in accordance with the planned design and by taking

appropriate mitigates actions to reduce adverse environmental impacts during project’s life cycle.

The project will create certain inevitable impacts, mainly during construction phase, although

within permissible limits as mentioned in Chapter 4 and can be reduced significantly with the

help of effective implementation of a well-designed EMP. The potential environmental impacts,

which need to be regulated, are mentioned below:

Noise pollution due to various noise generating equipment as well as vehicular

movement;

Water resource management to ensure continuous water supply.

Sullage generation from sanitary/domestic activities; and

Generation of municipal solid wastes from residences, maintenance of roads, parks,

common areas including constructional, electrical and plumbing wastes.

Energy conservation methods.

Maintenance of Building Management Systems and emergency aids.

To ensure better environment in & around the project site, effective EMP is developed

separately for construction and operational phase.

Integrated Township



CHAPTER 9


9.2 ENVIRONMENTAL MANAGEMENT STRATEGIES

Strategy for environmental management in construction work should be based on three-pronged

approach comprising of:

Pollution prevention.

Pollution control.

Protection of pollution recipients.

9.2.1 Topography and Physiography

During the development, construction and post construction phase of the Integrated Township

Project, no significant impact is anticipated on local or regional topography and Physiography,

hence exhaustive management plan is not required. It is however proposed to carry out extensive

turfing with local species apart from proposed plantations and greens.

9.2.2 Soil

9.2.2.1 Development & Construction Phase

During the construction phase, various kinds of wastes are generated that will be disposed in

varied ways. The following measures will be taken to prevent soil contamination at site and

ensure waste management:

Vegetation and top soil management:

Remove vegetative cover only from the specific site on which construction will take

place.

Plantation as proposed shall be started at the earliest.

The top soil will be stripped from constructional areas and stockpiled for later reuse in

landscaping.

Promote use of organic fertilizers.

Construction of erosion prevention troughs, as deemed necessary.

To prevent the erosion of excavated loose soil produced as a result of excavation, site

preparation activities and excavation work would be undertaken during dry season after

monsoon is over.

Construction Debris:

Integrated Township



CHAPTER 9


Fuel and oil would be stored in cement lined storage yard and handled carefully to

prevent soil contamination through leakage or spillage.

All metal, paper, plastic wastes, debris and cuttings would be collected from site as soon

as particular construction activity is over.

During construction of flexible pavement, bitumen wastes will be collected (if any) and

disposed in environmentally sound manner.

The number, frequency and area of movement of heavy machinery will also be restricted.

Recycling of construction wastes into aggregates for use in the project site.

Wastes from the labor camps will be collected and disposed as per the existing practices

in the site.

9.2.2.2 Post Construction Phase

To prevent soil contamination at site, the most important aspect is to manage the solid wastes

that will be generated during the operation phase. The Environmental Management Plan for the

solid waste focuses on three major components during the life cycle of the waste management

system i.e. collection, transportation, and treatment or disposal.

Collection and segregation of wastes

Solid waste generated from project would be collected door to door and segregated into

decomposable, recyclable and inert wastes.

Decomposable wastes will be decomposed and converted to manure to be used for

horticulture.

Recyclable waste would be sold to vendors.

Inert waste which comprises a very small amount of the total solid waste generated would

be temporarily stored within the project premises.

Waste bins would be placed at the strategic locations such as inter section of internal

roads, parks, common places, etc.

To minimize littering and odors, waste will be stored in well-designed containers/ bins

that will be located at strategic locations to minimize disturbance in traffic flow.

Integrated Township



CHAPTER 9


Care would be taken such that the collection vehicles are well maintained and generate

minimum noise and emissions. During transportation of the waste, it will be covered to

avoid littering.

Transportation:

Only the non-recyclable and non-biodegradable waste will be transported to the Govt. approved

agency. The segregation, transportation and disposal of wastes will be done by the authorized

agency that will take care of the waste management of the project during the operational phase of

the project.

Figure 9.1: Waste Management Flow Diagram

Disposal

With regards to the disposal/ treatment of waste, the management will take the services of the

authorized agency for waste management and disposal of the same on the project site during its

operational phase.

Integrated Township



CHAPTER 9


9.2.3 Hydrology

9.2.3.1 Ground water Hydrology

Development & Construction Phase

The water requirement during the construction period will be met water from existing pond and

borewell on the site.. The following are also proposed to further reduce the demand of

freshwater:

Curing water will be sprayed on concrete structures and free flow of water not allowed.

After liberal curing on the first day, all concrete structures will be painted with curing

chemical to save water to stop daily water curing hence save water.

Concrete structures will be covered with thick cloth/gunny bags and then water sprayed

on them to avoid water rebound and ensure sustained and complete curing.

Pools will be made using cement and sand mortar to avoid water flowing away from the

flat surface while curing.

Water ponding will be done on all sunken slabs. This will also highlight the importance

of having an impervious formwork.

Post Construction Phase

It is proposed to conserve groundwater resources through the combined means of water resource

development, minimized water consumption and reuse of treated sullage to reduce freshwater

demand.

9.2.3.2 Water Resource Development

In township development with mixed use of other buildings, each buildings (Plots, Group

Housing, Commercial, Public and semi public buildings) should be having their own self

sustainable design for storm water system with adequate nos, of RWH structure as per norms. At

the township level we will take care of paved green, roads and any surplus discharge from other

buildings in case sudden downpour. That has been considered 20% of their total runoff.

Rain water harvesting has been catered to and designed as per the guideline of CGWA for the

green paved and surplus discharge from other buildings . Peak hourly rainfall has been

Integrated Township



CHAPTER 9


considered as 45 mm/hr. The effective diameter and depth of a Recharge pit 3.20 m, and 2.40 m,

respectively is constructed for recharging the water

The bottom of the recharge structure will be kept 5 m above this level. At the bottom of the

recharge well, a filter media is provided to avoid choking of the recharge bore. Design

specifications of the rain water harvesting plan are as follows:

All gutter ends will be fitted with a wire mesh screen and a first flush device would be

installed. Most of the debris carried by the water from the rooftop like leaves, plastic bags and

paper pieces will get arrested by the mesh at the terrace outlet and to prevent contamination by

ensuring that the runoff from the first 10-20 minutes of rainfall is flushed off.

No sewage or wastewater would be admitted into the system.

No wastewater from areas likely to have oil, grease, or other pollutants has been connected to

the system.

CHAPTER 9


Storm water management system

Since the storm water on site will be harvested for ground water recharge, proper management of

this resource is necessary to prevent contamination. Hence, regular inspection and cleaning of

storm drains shall be carried out. Use of fertilizers and pesticides will be avoided prior to and

during monsoons. Clarifiers or oil/ water separators shall also be installed.

Minimal Water Consumption

To reduce the water consumption, awareness along the following lines will be spread amongst

the management and maintenance team:

Installation of water meters conforming to ISO standards at inlet and outlet point of

water supply.

To further lower the water consumption, options of Low flow flushing systems,

sensor based fixtures, and tap aerators etc. will be explored.

Leak detection

Drip irrigation for shrubs and trees

Use of low-volume, low-angle sprinklers for lawn areas

The message of water conservation will be spread amongst the residents through awareness

campaigns and pamphlets. Following tips shall be provided to the residents for conserving water.

Timely detection and repair of all leakages;

Turning off tap while brushing teeth;

Use of mug rather than running water for shaving;

Avoiding/minimizing use of shower/bath tub in bathroom;

Turning off faucets while soaping and rinsing clothes;

Using automatic washing machine only when it is fully loaded;

Avoiding use of running water while hand-washing;

Avoiding use of running water for releasing ice tray ahead of time from freezer;

Turning off the main valve of water while going outdoor;

Avoiding use of hose for washing floors; Use of broom may be preferred;

Integrated Township



CHAPTER 9


Watering of lawn or garden during the coolest part of the day (early morning or late

evening, hours) when temperature and wind speed are lowest. This reduces losses

due to evaporation.

Planting of native and/or drought tolerant grasses, ground covers, shrubs and trees.

Once fully grown, they need not to be watered frequently.

Avoiding over watering of lawns. Good rains eliminate the need for watering for

more than a week.

Setting sprinklers to water the lawn or garden only, not the street or sidewalk;

Avoiding installation or use of ornamental water features unless they recycle the

water and avoiding running them during drought or hot weather;

Installation of high-pressure, low-volume nozzles on spray washers;

Replacement of high-volume hoses with high-pressure, low-volume cleaning

systems;

Equipping spring loaded shutoff nozzles on hoses;

Installation of float-controlled valve on the make-up line, closing filling line during

operation, provision of surge tanks for each system avoid overflow;

Washing vehicles less often, or using commercial car wash that recycles water.

Re-use of treated sullage

It is expected that the project will generate approx. 3587 KLD of sullage. The sullage will be

treated in the STP of total capacity of 3720 KLD provided within the complex generating of

2869 KLD recoverable water from STP which will be recycled.

The treated sullage conforming to standards for effluent discharge on land will be reused to meet

various non-potable and non-contact requirements of the Integrated Township Project and its

residents.

9.2.3.3 Ground water Quality

Development and Construction Phase

To ensure against any groundwater pollution through leaching of soil, solid waste management

plan ensuring timely collection of wastes will be followed. The collected wastes will be stored at

Integrated Township



CHAPTER 9


designated area and disposed as per the standard procedures in line with the statutory

requirements.

Post Construction Phase

The ground water pollution can arise from improper waste handling or by recharge of

groundwater through contaminated storm water. A well planned solid waste management as

discussed in chapter 2 is proposed for the operation phase that will ensure against any chances of

soil or groundwater pollution on this account.

Storm water collects dirt and garbage along its flow. Contamination of this water with spilled oil/

grease is especially of concern when recharging is proposed. Hence, preliminary treatment for oil

and grease and filtration through layers of sand and gravel is proposed prior to recharge of the

groundwater.

Landscaping water enters the soil and finally the groundwater. It is thus of utmost importance

that only clean water is used for horticulture purposes. The water from the households will

contain significant amounts of detergent and soap that is undesirable for plants, soil and in

groundwater. Hence, it is proposed to treat sullage from the sites up to tertiary level, and be used

for landscaping only thereafter. Regular monitoring of treated sullage shall be carried out to

ensure that all parameters are within acceptable levels.

9.2.4 Air Quality

9.2.4.1 Development and Construction Phase

The construction phase for the Integrated Township project is about 2-3years, causing only

marginal impact on ambient air quality from constructional activities, unloading of construction

materials, cement, soil and vehicular movement etc. The main pollutant of concern is PM 2.5,

PM10 (dust). Likewise, following mitigation measures will be adopted during this phase to

mitigate the impacts on ambient air:

Installation of batch plant at isolated place and providing cover shed around

plants.

Loading and unloading of cement and other material in covered shed.

Providing dust suppression system in unloading area (as per requirement).

Developing avenue and curtain plantation on the internal roads and peripheral

plantation around the site to protect the movement of dust and other pollutants.

Integrated Township



CHAPTER 9


Cover scaffolding, hosing down road surfaces and cleaning of vehicles.

On-Road- Inspection for black smoke generating machinery.

Vehicles having pollution under control certificate will be allowed to ply.

Use of covering sheets for trucks to prevent dust dispersion from the trucks.

Reducing the speed of a vehicle to 20 km/hr to reduce emissions on site.

All material storages will be adequately covered and contained.

Training to the workers to reduce idling time of machines that otherwise tends to

produce hydrocarbons ad carbon monoxide.

Best practices for maintenance and repair of all machineries and equipments.


During the post construction phase, following measures will be adopted for pollution control in

the plotted residential Colony project:

Traffic pollution management

Plantation development

Power Back up: There is provision of 4 no. of DG sets of total 1, 270 kVA (1 X 320 kVA + 1 X

625 kVA + 1 X 125 kVA + 1 X 200 kVA) capacity for power back up in the Township Project

only for Public Utilities and External Lighting. The DG sets will be equipped with acoustic

enclosure to minimize noise generation and adequate stack height for proper dispersion.

Multistoried Group Housings, Commercial Building, Institutional Buildings etc. will have their

own standby supply arrangement.

Traffic pollution management: Internal roads would be maintained in good conditions to

control the dust emissions. Awareness will be raised amongst the residents for use of low sulphur

fuel.

Plantation development: Vegetation is an effective means for controlling air pollution due its

dual action of acting as a barrier between the source of emission and receptors and also as a sink

Integrated Township



CHAPTER 9


for various pollutants. It is proposed to develop plantation of species effective in absorption of

expected pollutants at site, along the internal roads and on the periphery of the Residential

Plotted colony project. Suggested species for plantation are:

Cassia Fistula(Amaltas)

DelonixRegia(Gulmohar)

Bauhinia purpurea(Kachnar)

Dalbergiasissoo(Shisham)

9.2.5 Noise Levels


During the construction phase, some noise will be generated through the operation of

construction machines, excavators, etc. Following measures would be taken; into consideration

to mitigate the noise at construction site:

Use of well-maintained equipment fitted with silencers and providing noise

shields near the heavy construction operations

Earmuff and other protection devices shall be provided to laborers working in

high noise generating machines.

High noise activities shall be carried out during daytime.

9.2.6 Post Construction Phase

The main sources of noise during this phase are the intermittent use traffic. The principles of

noise emission control and screening are proposed for noise generation.

Barriers:

Trees having thick and fleshy leaves with flexible petioles having capacity to withstand vibration

are suitable. Heavier branches and trunk of the trees also deflect or refract the sound waves. The

following species are proposed to be used in a greenbelt especially surrounding housing groups

and along the periphery of the project.

Ficus glomerata (Guler)

Polyathia longifolia (Debdaru )

Terminalia arjuna(Arjun)

Integrated Township



CHAPTER 9


9.2.7 Biological Environment

9.2.7.1 Development and construction phase

During the development, construction and post construction phase, no tree will be cut and

therefore no impact is anticipated on terrestrial ecology. Site clearing shall be carried out strictly

as per plan. Workers shall be advised against cutting, uprooting, coppicing of trees or small trees

present in and around the project site for cooking. Workers shall also be discouraged from

wandering in nearby areas with plantation or dense vegetation.

Further, green belt will be developed on the periphery and along the internal roads of project site

during the construction phase itself that will act as a curtain to restrict the movement of

pollutants from either side of the project and improve site aesthetics.

9.2.7.2 Post construction phase

During the post construction phase, green belt will be developed and maintained. Ornamental

plant species and grasses will be planted in open space within the premises. 30% area of net

planned area is proposed to be maintained green in the project site. Proposed list of species for

plantation is given below in Table 9.1:

opportunities which will have beneficial impact on the socio-economic conditions of the area.

Following suggestions are given to strengthen the beneficial impacts on the socio-economical

environment.

All the applicable guidelines under relevant acts and rules related to labor welfare and

safety shall be implemented during the construction work activities.

Proper sanitary and drinking water facilities should be provided to workers living in the

construction camps within the project premises.

Workers will be provided with appropriate PPEs during work.

Guarding of dangerous machine parts, maintenance of equipments as hoists and lifts will

be ensured.

SUMMARY AND CONCLUSION

10.1 PROJECT BACKGROUND

M/s DBH Township LLP intends to construct the Integrated Township Project at Village-

Ramchandi, Banarsi and Nakti, Distt. Raipur, Chhattisgarh.

As per EIA Notification, 2006 & its amendments for all Group Housing and area development

projects covering an area of 50 ha and/ or built up area greater than 1, 50,000m2 are designated

as category 8 (b) projects and are required EIA Report to obtain prior environmental clearance

from respective State Environmental Impact Assessment Authority (SEIAA). The project is thus

categorised as 8(b) under Schedule of the Environmental Impact Assessment Notification and

requires Environmental Clearance from the State Environment Impact Assessment Authority,

Haryana since the built up area is 1,033,801.19 m2. So, EIA/EMP study is required. The

EIA/EMP study has been carried out by Grass Roots Research & Creation India Pvt. Ltd.

For this study, the impact zone shall confine within an angular radius of 5 km from the project

boundary. For the purpose of certain environmental components, the radius has extended up to

10 km as well. The EIA is conducted to establish the baseline environmental setting in the study

area, assessment of potential impacts on different environmental components, design of

mitigation measures so as to keep impacts within acceptable limits and strengthen the positive

impacts.

The Executive Summary summarizes the findings of the EIA study to aid in decision making and

provides project related information and environmental impacts to non-technical sections of

society. The summary highlights the baseline environmental status, key environmental issues and

their likely impacts and also lists the major recommended mitigation measures to attenuate the

impacts.

10.4 ENVIRONMENTAL SETTING OF THE STUDY AREA

The baseline environmental status was assessed based on primary and secondary data collected

either through in-site field observation or obtained from agencies such as India Meteorological

Department (IMD), State Pollution Control Board, Census of India and Local Forest Department

etc. The baseline status established from analysis of secondary and primary data and predicted

impacts are discussed below. The proposed mitigation measures are also provided along with


The land use pattern of the study area is mainly residential, agricultural and open & degraded

vegetation. The site falls under residential land use as per Naya Raipur Development Plan 2031.

When awarded to the project proponent, the land was a barren stretch.

The project will be developed as per the provisions of the Naya Raipur Development Plan 2031.

The construction phase of any construction project poses the threat of soil contamination and soil

erosion, mainly during the construction phase. Inadequate solid waste management may also

cause soil contamination during operation phase. The estimated waste generation during

operation phase is 16,462 kg/day.

During construction phase, excavation related work will be avoided during the monsoons and

site clearing will be carried out for specific areas being developed. All wastes from site will be

regularly removed and disposed/ sold. An efficient solid waste management is proposed

comprising door-to-door waste collection, segregation of solid waste management facility within

the site, and their disposal. Solid waste will be disposed by sale of recyclable wastes to vendors.

10.4.2 Water environment

The project site is located at Village- Ramchandi, Banarsi and Nakti, Distt. Raipur, Chhattisgarh.

. The water requirement during construction phase will be met onsite borewell and pond. A

combination of efficient water management to reduce water consumption, reuse of treated

wastewater to reduce freshwater demand and rainwater harvesting to replenish groundwater is

proposed to have a positive bearing on the water environment of the region.

Sewage Treatment Plant (STP) of total capacity 3720 KLD will be set up to treatwaste water.

Integrated Township





During construction phase, the major air pollutant of prime concern is PM2.5,PM10as impacts of

other emissions such as SO2, NO2, and CO will not be significant because the nature of sources

is such that the emissions are distributed spatially as well as temporal. Monitored average

PM2.5,PM10 level exceeded NAAQS at all the five locations. The levels of PM 2.5,PM10,NO2, SO2

and CO at all the five locations were within the standards prescribed by NAAQS at all the five

locations. Thus dust emissions from construction activities shall require comprehensive

mitigation measures and best construction practices.

Water sprinklers will be used to suppress dust during construction. During the operation phase,

green belt and green area development is proposed to restrict and absorb air pollutants.


Noise levels were observed at four locations within the study area. Levels of background noise

monitored in exceed the limits at 55 dB (A) and 45dB (A) for daytime and night time

respectively.

The noise emitted from heavy-duty construction equipments during construction period being

high shall require occupational preventive measures and temporary noise barriers for noise

attenuation. The construction period being about four to five year duration, will require

significant mitigation measures such as restricted loud noise activities to daytime and provision

of PPEs In the operation phase, noise pollution will be checked through acoustic enclosures of

DG Sets and green belt plantation.

10.4.5 Biological environment

There is also no tree cutting involved in the project. Additionally, there will be avenue

plantations, green walls and roof tops. The landscaping will include native species that will

attract local birds and insects, reduce pollution and improve aesthetics and micro-climate of the

region. Total green area measures 91,860 m2i.e 10% of net planned area which will be area under

tree plantation at periphery and along the roads. Evergreen tall and ornamental trees like Acacia

auriculiformis, Acacia delbata, Aeglemarmelos, Adina cordifolia and ornamental shrubs like

Integrated Township




Bambusaarundinacia, Bambusa vulgaris have been proposed to be planted inside the premises.

Parks will also be developed by the project proponent.

List of the plants is given below in table 10.2

Table 10.2: Plantation List

Integrated Township




10.4.6 Socio-economic environment

The Integrated Township Project does not call for any land acquisition and no change in the

existing land use pattern. The execution of the project will not disturb the people living in area as

there will be no blasting and large scale digging. The project will generate employment

opportunities for both skilled and unskilled workers in the vicinity, which will produce multiple

effects on the life and economy of the local people. Thus from socio-economic point of view the

project is beneficial to the people and can be executed with little hesitation.

10.4.7 Energy efficiency

The total energy demand of 39.5 MVA for the project will be met by Chhattisgarh State Power

Distribution Company Limited. There is provision of 4 no. of DG sets of total 1, 270 kVA (1 X

Integrated Township




320 kVA + 1 X 625 kVA + 1 X 125 kVA + 1 X 200 kVA) capacity for power back up in the

Township Project only for Public Utilities and External Lighting. The DG sets will be equipped

with acoustic enclosure to minimize noise generation and adequate stack height for proper

dispersion. Multistoried Group Housings, Commercial Building, Institutional Buildings etc. will

have their own standby supply arrangement.

.Various provisions are made to reduce the energy efficiency of the building, such as use of solar

energy, provision of low energy fixtures, design features to maximise sunlight and use of

materials to improve energy efficiency.

10.4.8 Others

Resource Conservation:A concerted effort is made towards resource conservation by way of

using recycled building materials, reduced water consumption and improving energy efficiency

of the building.

Indoor Air Quality: Special attention will be given to maintaining indoor air quality through

use of low VOC paints, provision of adequate ventilation, proper storage of chemical and

cleaning materials.

Safety:A network of manned security gates, security men, closed circuit TV and intercom

facilities are proposed to ensure safety of the occupant. The buildings will also be provided with

adequate fire tenders, fire alarms and water sprinklers.

10.5 ENVIRONMENTAL MANAGEMENT PLAN Adequate environmental management measures will be incorporated during the entire planning,

construction and operating stages of the project to minimize any adverse environmental impact

and assure sustainable development of the area.

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

System (EMS) will be established at the site including an Environmental Management cell for

implementation of the EMP and monitoring plan, training and awareness, audits and

maintenance of records.

Integrated Township




The total estimated cost of the Integrated Township Project is Rs. 202.81 crores which includes

the cost of the land as well as the development cost.

Based on the environmental assessment, the associated potential adverse environmental impacts

can be mitigated to an acceptable level by adequate implementation of the measures as stated in

the EIA and the EMP. Some of the benefits from the project are:

Use of solar energy for street lighting

Provision of green walls and green terraces

Use of CLC blocks (containing approx. 33% flyash)

Use of steel manufactured from recycled content.

Provide permeable paving to control surface water runoff

Rainwater harvesting

Meet all requirements for buildings in moderate earthquake prone areas.

Provision of fire alarms and water sprinklers.

Provision of welfare schemes to workers.

Extending educational and healthcare facilities to the local people.

Commitment to engaging local people and businessmen for maintenance and

repair work.

Hence, it may be concluded that the project will have significant positive economic and social

impact on the local community apart from meeting the housing needs of the occupants, without

bearing any significant adverse environmental impact
