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

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.

Since air-cooled DG set will be used, there will be no requirement of water for DG set cooling.
Therefore calculation for DG Cooling has not been considered for average water requirement
throughout the year.
Water Balance for Rainy season
During rainy season there shall be no demand of water for horticulture and thus this excess
amount of water will be used in nearby construction activity. Only emergency discharge will be
made to sewer.

The proposed STP within the project site will be based on MBBR technology which will be
installed by the proponent to take care of the discharge from the project. The expected recovery
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.

(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
M/s DBH Township LLP. Page 25
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.

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
At Village Banarsi, Ramchandi and Nakti
Raipur, Chhattisgarh EIA/EMP REPORT
CHAPTER 2
M/s DBH Township LLP. Page 27
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.

M/s DBH Township LLP. Page 28
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.

From above rainfall pattern it is clear that over all rainfall at the site is found to be very less, so it
explains soil erosion will not be much significantly at the site. Although M/s DBH Township
LLp. will take all preventive measures to prevent soil erosion. To conserve water, a rainwater
harvesting system is proposed across the project. Since the existing topography is congenial to

2.11 SOLID WASTE MANAGEMENT
Waste quantification is carried out to estimate the amount of waste generated by different
activities in the project site. For estimation of quantity of solid waste generated from the project,
waste generation factors are selected for each activity based on case studies available for similar
type of projects, assumptions and past experience.
2.11.1 Solid Waste Generation
Solid waste generation rate as 0.25 Kg/Capita/day for staff and 0.15 Kg/Capita/day for visitors
and 0.50 Kg/Capita/day for residents have been considered which generates about 16,462 kg/day
for the entire area. Collection systems comprise waste containers at ground floor of each tower,
the solid waste collected in garbage room shall be disposed to the appropriate site as per
municipal authority. The solid waste so generated shall be first segregated as plastic, glass, paper

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

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
At Village Banarsi, Ramchandi and Nakti
Raipur, Chhattisgarh EIA/EMP REPORT
CHAPTER 3
M/s DBH Township LLP Page 48
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.

CHAPTER 3
M/s DBH Township LLP Page 55
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 WATER ENVIRONMENT
3.4.4.1 Water Quality
Water quality assessment is one of the essential components of EIA study. Such assessment helps in
evaluating the existing health of water body and suggesting appropriate mitigation measures to minimize
the potential impact from development projects. Water quality of ground water has been studied in order
to assess water-uses in construction, drinking, cooling and horticulture purpose.

The water quality at the site and other locations within the 5 km impact zone was monitored during Oct
2015 to Dec 2015. The locations of the monitoring sites are depicted in Annexure VIII(c) and the result
of the monitoring and analysis of ground is presented in the Annexure IX.
3.4.4.2 Sampling Frequency and Sampling Techniques
Parameters for analysis of water quality were selected based on the utility of the particular source of
water as per MoEF guidance. Hence quality of ground water was compared with IS: 10500: 1991
(Reaffirmed 1993 With Amendment NO -3 July 2010) for drinking purposes.
As per the standard practice, one sample from each station was taken each month in the study period.
Sampling was done by standard sampling technique as per the Standard Methods. Necessary precautions
were taken for preservation of samples. Location of Ground Water Sampling Sites Sampling Sites is

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.

CHAPTER 3
M/s DBH Township LLP Page 67
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

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.

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

CHAPTER 3
M/s DBH Township LLP Page 82
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.

CHAPTER 3
M/s DBH Township LLP Page 83
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
At Village Banarsi, Ramchandi and Nakti
Raipur, Chhattisgarh EIA/EMP REPORT
CHAPTER 3
M/s DBH Township LLP Page 91
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
At Village Banarsi, Ramchandi and Nakti
Raipur, Chhattisgarh EIA/EMP REPORT
CHAPTER 3
M/s DBH Township LLP Page 92
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
Integrated Township

CHAPTER 3
M/s DBH Township LLP Page 93
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.
The overall impact of the project is expected to be positive for the habitants of the area and the persons
associated with the project.

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.

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

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.

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
At Village Banarsi, Ramchandi and Nakti
Raipur, Chhattisgarh EIA/EMP REPORT
CHAPTER 4
M/s DBH Township LLP. Page 102
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.
4.5.5 Air Environment
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
At Village Banarsi, Ramchandi and Nakti
Raipur, Chhattisgarh EIA/EMP REPORT
CHAPTER 4
M/s DBH Township LLP. Page 103
• 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
At Village Banarsi, Ramchandi and Nakti
Raipur, Chhattisgarh EIA/EMP REPORT
CHAPTER 4
M/s DBH Township LLP. Page 104
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.

CHAPTER 4
M/s DBH Township LLP. Page 105
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

Raipur, Chhattisgarh EIA/EMP REPORT
CHAPTER 4
M/s DBH Township LLP. Page 107
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.

4.6 ASSESSMENT OF THE ENVIRONMENTAL IMPACTS DURING OPERATION
PHASE
4.6.1 Land Environment
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
M/s DBH Township LLP. Page 109
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.
4.6.3 Air Environment
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
M/s DBH Township LLP. Page 111
• 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:

Low incremental value was predicted from DG sets due to high stack height of 30 m. No
significant impact was envisaged due to proposed DG sets to be installed at site.

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.

4.6.4 Noise Environment
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
At Village Banarsi, Ramchandi and Nakti
Raipur, Chhattisgarh EIA/EMP REPORT
CHAPTER 4
M/s DBH Township LLP. Page 116
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.

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 multi- storied 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
M/s DBH Township LLP Page 119
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.

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
At Village Banarsi, Ramchandi and Nakti
Raipur, Chhattisgarh EIA/EMP REPORT
CHAPTER 5
M/s DBH Township LLP Page 121
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
At Village Banarsi, Ramchandi and Nakti
Raipur, Chhattisgarh EIA/EMP REPORT
CHAPTER 5
M/s DBH Township LLP Page 122
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.

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).

CHAPTER 5
M/s DBH Township LLP Page 124
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
At Village Banarsi, Ramchandi and Nakti
Raipur, Chhattisgarh EIA/EMP REPORT
CHAPTER 7
M/s DBH Township LLP Page 134
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
If indoors:
1. Take cover under a piece of heavy furniture or against an inside wall and hold on.
2. Stay inside: The most dangerous thing to do during the shaking of an earthquake is to try to
leave the building because objects can fall on you.
If outdoors:
Move into the open, away from buildings, streetlights, and utility wires. Once in the open, stay
there until the shaking stops.
If in a moving vehicle:
Integrated Township
At Village Banarsi, Ramchandi and Nakti
Raipur, Chhattisgarh EIA/EMP REPORT
CHAPTER 7
M/s DBH Township LLP Page 135
Stop quickly and stay in the vehicle. Move to a clear area away from buildings, trees, overpasses,
or utility wires. Once the shaking has stopped, proceed with caution. Avoid bridges or ramps
that might have been damaged by the quake.
After the quake
1. After the quake be prepared for aftershocks.
2. Although smaller than the main shock, aftershocks cause additional damage and may bring
weakened structures down. Aftershocks can occur in the first hours, days, weeks, or even
months after the quake.
Help injured or trapped persons.
1. Give first aid where appropriate. Do not move seriously injured persons unless they are in
immediate danger of further injury. Call for help.
2. Remember to help those who may require special assistance--infants, the elderly, and people
with disabilities.
3. Stay out of damaged buildings.
4. Use the telephone only for emergency calls.
7.3.2 Response Procedure for Emergency Team
1. Formulate an Emergency Response Team for earthquake response.
Using the public address system, inform residents of response procedures discussed above.
2. Inform the necessary authorities for aid.
3. Ensure no person is stuck beneath any debris, in case of a structural failure.
4. Ensure that all occupants standing outside near the buildings are taken to open areas.
5. Ensure that the first aid ambulance and fire tender vehicles are summoned if necessary.
6. Inform the nearby hospitals if there are any injuries.
7. Check the utilities and storage tanks for any damage.
7.4 RESPONSE FOR LPG LEAKAGE
1. The affected area should be evacuated and cordoned off immediately

4. Ensure that only concerned personnel are present in the affected area and all other personnel
and visitors are moved to the nearest assembly points.
5. Rescue trapped personnel, also check if any personnel are unconscious in the area and
immediately move them outside and provide first aid. Ambulance should be summoned to take
injured personnel to the nearest hospital.
6. Personnel in the nearby buildings to close all doors and windows to prevent entry of the leaked
gas.
7. Source of leakage to be traced and isolated from all the other areas. And if required use
pedestal fans to bring down the gas concentration.
8. In case of a fire follow the instructions in case of fire.
7.5 RESPONSE IN CASE OF FIRE
1. Required response during in the event of a fire should be described in signs located in the
lobby.
2. On sighting a fire, it should be immediately informed to the environment manager
giving the exact location and type of fire in detail.
3. Initiate the Emergency Response Team for fires.
4. If the fire is small, engage in extinguishing the fire using the nearest fire extinguisher.
5. Guide the Emergency Response Team staff to the emergency assembly point.
6. The Emergency Response Team should immediately inform the nearest dispensary and
security force. If required a fire tender should be summoned.
7. The response team should immediately move to the point of fire and take all necessary steps to
stop the fire. If the fire is not controllable and spreads then the manager in charge should inform
the district authorities and call for external help.

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

Raipur, Chhattisgarh EIA/EMP REPORT
CHAPTER 7
M/s DBH Township LLP Page 138
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
At Village Banarsi, Ramchandi and Nakti
Raipur, Chhattisgarh EIA/EMP REPORT
CHAPTER 7
M/s DBH Township LLP Page 139
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

CHAPTER 7
M/s DBH Township LLP Page 140
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.

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.

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
At Village Banarsi, Ramchandi and Nakti
Raipur, Chhattisgarh EIA/EMP REPORT
CHAPTER 9
M/s DBH Township LLP Page 145
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
At Village Banarsi, Ramchandi and Nakti
Raipur, Chhattisgarh EIA/EMP REPORT
CHAPTER 9
M/s DBH Township LLP Page 146
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.

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

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.

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
M/s DBH Township LLP Page 152
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
At Village Banarsi, Ramchandi and Nakti
Raipur, Chhattisgarh EIA/EMP REPORT
CHAPTER 9
M/s DBH Township LLP Page 153
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
M/s DBH Township LLP Page 154
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.
9.2.4.2 Post Construction Phase
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
M/s DBH Township LLP Page 155
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
9.2.5.1 Development and Construction Phase
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 )

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:

9.2.8.2 Post Construction Phase
The project envisages addressing the wider goal of environmental protection through a social
investment strategy for the communities around the project. The project seeks to increase the
benefits to the local population and contribute towards meeting community’s expectation of
benefits from the project.
Some of the concerns raised by local people relate directly to the project. Concerns and
aspirations not directly related to the project were also solicited so as to identify areas that could
be addressed through socially responsible initiatives and interventions. These were:
a) Demand for employment opportunities.
b) Infrastructure development

The proposed strategy envisages addressing the wider goal of sharing benefits with the local
community. The following activities would be undertaken.
Income Generation Opportunity for local community
The local people will be given preference, although they will be recruited on their individual
merit. Tender specification for post construction services will include favorable employment
opportunities towards the local population. The main principles of employment are outlined
below:

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
10.4.1 Land Environment
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.

10.4.3 Air Environment
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.
10.4.4 Noise Environment
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

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
At Village Banarsi, Ramchandi and Nakti

M/s DBH Township LLP Page 176
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.
