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 mitigation measures are in place and effective.

1.14 EIA METHODOLOGY

The project may have impact on the physical, biological and socio economic attributes of

surrounding environment. In assessing the environmental impact, collection, collation and

interpretation of baseline data is of prime importance.

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

an early stage of project planning and design. 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.)

Identification of environmental impacts.

Evaluation of impacts leading to preparation of environmental management and

monitoring plan.

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.

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

The process has long retention time and can absorb shock load situation.

Reduced net daily water requirements, source for Flushing and Horticultural purposes by

utilization of the treated wastewater.

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

The process produces a well-oxidized sludge in small quantities only, which can be

removed and used as manure.

c. Treatment Technology

MBBR TECHNOLOGY

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

PROCESS DESCRIPTION

The Sewage Treatment Plant shall be designed to receive continuous sewage inflow within the plant

room allocated on the site plan. The ease of maintenance and operation is of utmost importance in the

design of Sewage Treatment Plant.

The design of the Sewage Treatment Plant shall be such that it can be installed within the allocated

space and shall be subjected to the approval of the Construction Manager / Consultant.





STP is proposed to use Moving Bed Bio Reactor (MBBR) process with UV for the treatment:

The treatment plant shall be designed with a capacity to handle 200 KLD of sullage for Phase I and

114 KLD of sullage for Phase II. Sewage and Wastewater will flow via gravity collection system

through a bar screen chamber to a sump chamber. A bar screen shall be provided at the inlet point in

the bar screen chamber and the sewage will flow through this bar screen into the sump. Bar screen

shall also be designed that it can be cleaned manually by going down to a platform in the chamber.

Two horizontal centrifugal pumps shall be provided in the sump to pump the collected sewage water

to the reactor. Air will be introduced in the sump through pipe grid, to avoid the sewage from

becoming septic.

Wastewater from the sump shall be lifted by means of effluent lifting pumps into Equalised Reactors

where BOD/COD reduction is achieved by virtue of aerobic microbial activity. Reactor would be

running in series. Oxygen required will be supplied through course bubble air diffusers.

The excess bio-solids washed in the biological process are separated in the downstream Clarifier/ Tube

Settler Tank. The clear supernatant will be collected in the Chlorine water tank cum filter feed tank.

The treated sewage is further pumped through filtration units. The sewage after CCT is disinfected and

shall meet the coliform norms of < 1000 counts with minimal dosage of sodium hypochlorite. The

coliform count in the treated effluent shall be almost nil.

The tertiary treatment consists of removing the residual suspended solid load, by filtering through

Dual Media Filter and passing the water through Activated Carbon Filter so that traces of BOD/COD

and excess chlorine are removed. The treated sewage shall be passed through Ultra Violet system (if

required) for water requirement for flushing purpose.

The biological sludge generated from the reactor which is settled in the Clarifier/Tube settler, is

pumped into sludge sump. Sludge shall be stored in the sludge holding tank for final dewatering and

disposal through screw pump and Centrifuge. The treated effluent from the Sewage Treatment Plant

shall be stored in Treated water storage tanks. The treated water is to be used for the horticulture and

flushing purpose. This treated shall be further softened and used for cooling tower make up.





DESIGN PARAMETERS

Total flow rate: 314 m3/ day

Nature of wastewater: Combined Sewage

Figure 2.3: Schematic Diagram of the Sewage Treatment Plant

2.9 RAINWATER HARVESTING

The storm water disposal 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. Storm water from various buildings shall be connected to adjacent drain by a pipe

through catch basins. Therefore, it has been calculated to provide 14 rainwater harvesting pits at

selected locations which will catch the maximum run-off from the area.





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

drains is planned adjacent to roads. All building roof water will be brought down through rain

water pipes.

2) Proposed storm water system consists of pipe drain, catch basins and seepage pits at regular

intervals for rain water harvesting and ground water recharging.

3) For basement parking, the rainwater from ramps will be collected in the basement storm water

storage tank. This water will be pumped out to the nearest external storm water drain.

4) The peak hourly rainfall of 45 mm/hr shall be considered for designing the storm water

drainage system.

Rain water harvesting has been catered to and designed as per the guideline of CGWA. Peak hourly

rainfall has been considered as 45 mm/hr. The recharge pit of 3 m length, 3 m width and 2.25 m depth

is constructed for recharging the water. Inside the recharge pit, a recharge bore is constructed having

adequate diameter and depth. The ground water level in the area is 30-40 meters bgl. 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:

Catchments/roofs would be accessible for regular cleaning.

The roof will have smooth, hard and dense surface which is less likely to be damaged allowing

release of material into the water. Roof painting has been avoided since most paints contain

toxic substances and may peel off.

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.

Calculations for storm water load in Phase-I:

Plot Area of Phase-I = 25,454.73 m2





Roof-top area = Ground Coverage of Pocket-A = 8,810 m2

Green Area = 10,708.66 m2

Green Area (without water body) = 7,870.8 m2

Paved Area = Plot Area – (Roof-top Area + Green area)

= 25,454.73 – (8,810 +10,708.66)

= 5,936.07 m2

Runoff Load

Roof-top Area = 8,810 × 0.045 × 0.80

= 317.16m3/hr

Green Area =7,870.8× 0.045 × 0.20

(Without water body) = 70.84 m3/hr

Paved Area = 5,936.07 × 0.045 × 0.70

= 186.986 m3/hr

Total Runoff Load = 317.16+ 70.84 + 186.986 m3/hr

= 574.986 m3/hr

Taking 15 minutes Retention Time, Total volume of storm water = 574.986/ 4

= 143.747 m3

Taking the effective length, width and depth of a Recharge pit 3 m, 3 m and 2.25 m respectively,

Volume of a single Recharge pit = l x b x h = 3 × 3 × 2.25 = 20.25 m3

Hence No. of pits required = 143.747 / 20.25 = 7.1 pits say 7 pits

Calculations for storm water load of Phase-II:

Plot Area of Phase-II= 20,436.62 m2

Roof-top area = Ground Coverage of Pocket-B= 9,348 m2

Green Area = 6318.5 m2


= 20,436.62 – (9,348 + 6318.5)

= 4,770.12 m2





Runoff Load

Roof-top Area = 9,348 × 0.045 × 0.80

= 336.528 m3/hr

Green Area =6,318.5× 0.045 × 0.20

= 56.87 m3/hr

Paved Area = 4,770.12 × 0.045 × 0.70

= 150.259 m3/hr

Total Runoff Load = 336.528 + 56.87 +150.259 m3/hr

= 543.657 m3/hr

Taking 15 minutes Retention Time, Total volume of storm water = 543.657 / 4

= 135.914 m3



Hence No. of pits required = 135.914 / 20.25 = 6.7 Pits say 7 pits

As 1 pit/acre is required so, total 14 rain water harvesting pits will be required for 14.025 acre land.

Total of 14 Rain Water Harvesting pits are being proposed for artificial rain water recharge within the

project premises.

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 March-May, 2015. Apart from field monitoring, additional data was

also collected from secondary sources like Irrigation Department, India Meteorological Department

(IMD), Central Ground Water Board, Geological Survey of India, State Ground Water Department,

State Pollution Control Board, Census of India and Local Forest Department, Non -Governmental

Agencies etc.

3.3 STUDY AREA

The site development area spreading across 56,757.16 m2 (14.025 acres) is a vacant land earmarked for

development of Group Housing Colony as per Gurgaon Manesar Urban Complex 2021. The probability

of impacts from the Group Housing Colony 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 (10 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 map

showing location of project site and surroundings within 10 km is enclosed as Annexure IV (b)

respectively. For biological studies, considering the ecological connectivity and widespread habitats of

wildlife, a 15 km radius around the project area has been considered for secondary data collection and

the map showing the same is attached as Annexure IV (c).

3.4 BASELINE MONITORING OF ENVIRONMENTAL COMPONENTS

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.

3.4.1 Meteorology

A meteorological station was set up at the project premises. Meteorological data was generated during

the March-May 2015.

The following parameters were recorded at hourly intervals continuously during monitoring period:





- Wind speed

- Wind direction

- Air temperature

Table-3.1 gives summarized meteorological data for the worst day. Figure-3.1 gives the wind-rose

3.4.2 Air Environment

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. The location showing the air quality monitoring stations is

enclosed as Annexure VI.

AAQ5 Tigra NW 2.13

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

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 (220 mg/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 VII 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.

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 5 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. Five sampling locations were selected for the sampling of noise levels. The sampling

locations are given in Table-3.4 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 10 km impact zone was monitored during

March 2015- May 2015.

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. Ground water quality was

analyzed for parameters as mentioned in the ‘Methods of Monitoring & Analysis published by CPCB (in

Annexure –IV of CPCB guidelines)’ and it was rated according to the CPCB Water Quality Criteria

against A, B, C, D & E class of water based on parameters identified in the criteria. Water samples were

collected as Grab water sample from sampling location in a 5 liter plastic jerrycan and 250 ml sterilized

clean glass/pet bottle for complete physico-chemical and bacteriological tests respectively. The samples





were analyzed as per standard procedure / method given in IS: 3025 (Revised Part) and standard method

for examination of water and wastewater Ed. 21st, published jointly APHA, AWWA and WPCF.

The ground water quality is compared with CPCB water quality criteria mentioned in Table 3.7:

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 is attached as

Annexure VI.

Table 3.8: Location of Water Sampling Sites

3.4.4.3 Result & Conclusion:

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

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

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

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

metals from surface and 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

Comparing the values of pH, DO, BOD and total coliforms with ‘Use based classification of ground

waters’ published by Central Pollution Control Board; it can be seen that the analyzed ground

waters can be compared with class ‘E’ and can be used as drinking water sources after conventional

treatment and disinfection. Bacteriological examination of ground water indicates the presence of total

coli forms, which may be due to human activities observed during the study period.

Rainwater Harvesting:

The main source of ground water recharging in the study area is rainwater, which infiltrates into the

ground through various litho logical units present in the study area. 30 number of rainwater harvesting

pits shall be installed to recharge the ground water. The runoff from the rooftop and storm water shall go

to the recharge pits.

Scheme for Ground Water Recharging

The rainwater will be diverted from the rooftop using rain water pipes to the surface / underground

drainage network. The entire building plot shall be sub divided for recharging structures.

It has been proposed to provide recharge pits for the desired purpose. The rainwater will be diverted into

the desilting tank to remove inorganic impurities and the outflow of the desilting tank will be taken into

the recharge well.

Desilting Tank

The desilting tanks are used to remove silt and other floating impurities from rainwater. Desilting tank is

like an ordinary container having provision for the inflow, outflow and overflow. Apart from removing

silt it holds the excess amount of water till it is soaked up by the recharge structure. The bottom of tank

will have unpaved surface (layers of coarse sand) to allow standing water to percolate into the soil.

Recharge well/pit

Rain water harvesting has been catered to and designed as per the guideline of CGWA. Peak hourly

rainfall has been considered as 45 mm/hr. The recharge pit of 3 m length, 3 m width and 2.25 m depth is

constructed for recharging the water. The ground water level in the area is 30-40 meters below ground

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

media is provided to avoid choking of the recharge bore. Design specifications of the rain water

harvesting plan are as follows:


The roof will have smooth, hard and dense surface which is less likely to be damaged allowing

release of material into the water. Roof painting has been avoided since most paints contain toxic

substances and may peel off.

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 sullage would be admitted into the system.

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

system.

It should be therefore concluded that there is no significant impact on surface water quality & hydrology

of the area. The proposed rainwater-harvesting scheme will stabilize the groundwater table in the area.

The schematic diagram of rainwater harvesting pit is shown in Figure-3.2.

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 99.25 m-100.25 m. The

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

environment of the study area within 5 km radius.

3.4.5.2 Land Use Description

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 74.49% of the study area. The land use data are presented in

Table 3.9 and also highlighted with a pie chart at Figure 3.3. The landuse /land cover map is presented

in Annexure VIII.

Landform and Terrain analysis: According to the study of 10 km radius around the project in

topographical map of scale 1:10000, it was found that 40.82% is Agriculture, 19.86% is settlement,

0.11% is water bodies, 0.08% area is vegetation, 0.35% is forest, 34.73% is Open scrub & 4.05% is open

land. Complete details are given in Figure 3.3 above. Project site is a vacant land.





Soil:

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

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

studied at 3 different locations.

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

characterization. The locations of the monitoring sites are depicted in Table 3.8 (a), Monitoring maps

are attached as Annexure VI and the results of the monitoring and analysis is presented in the Table

3.10 (c).

Methodology

The soil samples were collected in the April, 2015 from 3 locations as given in above Table 3.10(a). At

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

to 30 cm below the surface. The final 5 samples represent homogenously mixed soil from these 3 sub-

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

and site name and sent to laboratory for analysis. Table 3.8(b) gives the idea of the frequency and

methodology of selection of soil sampling stations and monitoring process.

3.4.6 Biological Environment

3.4.6.1 Biological Environment

Literally environment stands for the totality of surrounding conditions. Animals and plants form a vital

part of this sum total. Flora and fauna of an area are inter-related to each other and have a very crucial

impact on human life. With changes in environmental conditions, structure, density and composition of

plants and animals undergo changes as well. The present study was carried out in two separate headings

for floral and faunal community. The aspects to be covered in the study for the project are given in

Table 3.11.

D. Wild life and avifauna

Methodology

Detailed survey was conducted to evaluate faunal composition of the study area (core and buffer zone)

within the project area. Primary data like faunal composition was recorded during site visit and

secondary data was collected from the Forest department to get the correct picture of the study area. The

major portion of the study consists of agricultural field and human settlements which support wildlife

habitat insignificantly.

The survey methods used for faunal assessment are:

1. Walkthrough method

2. Direct Count Method- birds, mammals

The major part of the study area lies under agriculture field and human settlements which restricted the

wildlife habitat significantly. Most of the mammalian species reported in the study area are common

fox, and Indian hare. There is neither any wildlife sensitive area nor any corridor for the movement of

wildlife present in the study area. There are many small ponds present in the buffer zone of study area

which are the major attraction sites for avifauna. Common Maina, Kingfisher, Spotted dove, Pintail and

Pond Heron are some dominant bird species present in the study area. There is no information regarding

migratory movement of birds in the study area. As far as the reptiles community was concerned, Krait

and house lizard are reported from the study area.

3.8.3 Aquatic life

The Phytoplanktons in the lakes are basically dominated by filamentous forms. The dominant ones are

Chaetophora sp., Cladophora sp., Spirogyra sp. The Zooplanktons are basically dominated by

Crustaceans and Rotifers.

3.4.7. SOCIO ECONOMIC IMPACT ASSESSMENT

3.4.7.1 Background

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

economic characteristics of the human beings living in a given geographical area during the period of

study. The geographical area is called Study Area or Impact Area. SEIA is carried out separately but





concurrently with Environment Impact Assessment (EIA). The study area consists of core and buffer

area encircling the project area. The Socio-Economic Impact Assessment focuses on the likely effect of

the project on social and economic well-being of the community. The impact may be direct or indirect,

positive or negative.

In this part of the EIA report an attempt has been made to assess the Socio-Economic Impact of Group

Housing Colony Project located at Village Nangli Umarpur, sec-62, District Gurgaon in the state of

Haryana.

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.

SCOPE

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 living in the study area.

c) To assess the probable impact of the project on social and 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.

METHODOLOGY

For Socio-Economic Impact Assessment of the project, GRC India carries 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 (village/town), a specified number of representative households were selected scientifically

for collection of information through face to face interview 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 villages/towns located in the core area were surveyed for

the collection of information. Further, in each village/town 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 village/town is time consuming and expensive, the Sample Survey approach was

adopted for collection of information from the selected households in the villages/towns.

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, Sample Survey was conducted for the collection of data.

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 and household) was decided by using the formula = √ {(1.96

*σ)/Δ}; where n= 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/towns by

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

a given village/town.

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.

SURVEY INSTRUMENTS

The following Schedules/Questionnaires were developed for collection of Primary data:

Questionnaire-1A: Village Particulars

Questionnaire-1B: Town Particulars

Questionnaire-2: Household Particulars.

Each Questionnaire is divided into several blocks and there are both open-ended and closed-ended

questions.

CHRONOLOGY OF VARIOUS STEPS TO PREPARE THE SEIA REPORT IS AS UNDER:





STUDY AREA

There are 54 identified habitations in the study area which are distributed in rural area and various

municipal wards and colonies of the urban areas of the study area. All the habitations are spread over in

several sub-districts viz., Pataudi, Gurgaon, Farrukhnagar, Manesar and Sohna of district Gurgaon in the

state of Haryana.

The Land Use Pattern of the Study Area is given in the table below:

It may be seen from the above table that 68.4 per cent of the total geographical area is cultivable land,

12.4 per cent is cultivable waste and the remaining 19.2 per cent is the ‘Area not available for

Cultivation’. Of the total cultivable land, 84.6 per cent is irrigated land and the remaining 15.4 per cent

is un-irrigated land.

SOCIO-ECONOMIC IMPACT OF THE PROJECT

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 2,985 including staffs, visitors and residential population increases

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

The proposed project will provide employment to the local people. 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. This





is a positive impact of the project.

Impact on Road Development

Movement of heavy vehicles to & fro the project site is expected during the construction period. Hence,

there is good 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 and safety of all the

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

ensure that the machinery and equipment in use is 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

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

ANTICIPATED ENVIRONMENTAL IMPACTS & MITIGATION

MEASURES

4.1 INTRODUCTION

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

Group Housing Colony. 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. Group Housing Colony

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 Group Housing Colony 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 Group Housing Colony project are likely to have some impact on the

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

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

project on various environmental parameters during construction and function phase respectively





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

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 EMAAR MGF Land Ltd.

It is further proposed to maintain 30% 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: Group Housing Colony will be developed as per Gurgaon- Manesar Urban Complex

2021 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 Group Housing Colony, 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 Group Housing Colony. 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.

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 Group Housing Colony, rich aquifers are present. Water

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

be met by recycled water from STP. Water will be required for site preparation activities dust

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

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

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

insignificant during construction of project.

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

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

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

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

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

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

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





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

flat surface while curing.

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

of having an impervious formwork.


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

development phase of the project will be as follows:

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

Emissions from power generator at site;

Emissions from the operation of construction equipment and machines;

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.

Assessment of the impact from Diesel Generators: Emissions from the D.G. Set during

construction phase may cause some localized impact on ambient air quality for short duration, as

it will be operated during power failure only. It may be noted that the D.G. Set power will be

used to operate construction equipment only if required. Adequate height of stacks and acoustic

erective will be provided to the D.G. Set as per guidelines of CPCB to facilitate the dispersion of

flue gases into the atmosphere.





Mitigation Measures: It is proposed to provide adequate dust control systems in the form of

installation of batch plants, and loose material handling in covered sheds. Dust suppression

system is also to be provided where necessary. Provision for treatment of DG Flue Gas emissions

in a scrubber will be considered. It is further proposed to cover scaffolding, hosing down road

surfaces and cleaning of vehicles especially during the dry season. Avenue and curtain plantation

on the internal roads and peripheral plantation around the site will also be developed.

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 the operation of D.G. Sets

Generation of noise during concreting, hammering, etc.

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

Colony 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)

D.G. Set 85 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. Noise modeling

results for construction phase have been given in Table 4.4.

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

the existing, ambient noise levels at project site but restricted to small distance (maximum up to

4.3 km) and only during daytime. 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. D.G. Sets with proper acoustic

enclosure for controlling noise would be installed.

4.5.7 Terrestrial Ecology

Impact: There is no loss of forestland due to the construction of the Residential Group Housing

Colony. 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 Group Housing Colony. Therefore, overall

positive impact is anticipated on economy of the area due to development and construction

activity of the Group Housing Colony.

4.5.9 Socio-Economic

During the development and construction of Group Housing Colony, about 150 to 200 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 Group Housing Colony will be developed gradually in the time span of about 2 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,

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


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 Surface water hydrology

Impact: During the post construction phase, no water will be taken from surface water bodies in

the area. Further, adequate drainage will be provided at the project site to channelize the storm

water for rainwater harvesting.

The sewage effluents generated from the project will be collected through the sewer line network

provided in the project site for treatment in the Sewage Treatment Plant (STP), and the treated

wastewater reused within the site thereafter. Therefore, impact on the surface water hydrology

will be insignificant during the post construction phase.

Mitigation: It is proposed to provide rainwater harvesting across the project site. The roof tops

of buildings will also be connected to the rainwater collection system. This will not only reduce

the pressure of stormwater management system of the city but also recharge groundwater.

4.6.2.2 Ground water hydrology

Impact: During post construction phase, the total water requirement of the Group Housing

Colony is approx. 482 KLD out of which total domestic water requirement is 360 KLD. The

fresh water requirement is approx. 257 KLD (which is 70% of the domestic water demand). The

water will be supplied by HUDA. 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 as well as roof top of the buildings. 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.





4.6.2.3 Surface Water Quality

Impact: The sewage effluent generated from the Group Housing Colony will be collected

through the sewer line network provided in project and treated in Sewage Treatment Plants

(STP’s) of capacity STP of 240 & 135 KLD.

Mitigation Measures: As no significant impact is anticipated on the water bodies of the region,

no mitigation measures are suggested.

4.6.2.4 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

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 Group Housing Colony will be well maintained. Solid waste

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

leaching.


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

population of Group Housing Colony. Vehicular emissions will be major source of air pollution

in addition to DG set. 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.

Emission sources from D.G. Sets.

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

traffic movement & DG sets. 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.

7 nos. of D.G. sets of total capacity 2,780 KVA (2 X 500 KVA + 2 X 320 KVA+3X 380 KVA)

will be provided for back up electricity supply during power failure. This will cause emission of

PM, SO2, NO2 and CO. However, since the D.G. sets will be operational only during power

failure and low sulphur diesel will be used; therefore, pollutants incremental load in the ambient

air environment will be expected to be minimal. However, an adequate stack height of D.G. Sets





will be provided as per the stipulated guidelines of Central Pollution Control Board (CPCB) to

facilitate proper dispersion of exhaust gases as given below considering height of the building:

ISCST3 dispersion model was used to predict GLC caused by a single point source (3 stacks)

at each receptor of 100 m x 100 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 proposed project, NO2 was the worst affected pollutant released into the

atmosphere (Table 4.5). 24-h GLC were predicted for SO2, NO2, CO and PM but isopleth of

NO2 is only presented in the report as GLC of other pollutants were lower under similar

meteorological conditions.

Mitigation Measures: In the group housing colony, 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.


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 to the personnel engaged in D.G. Set room. 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 17,027.16 m2 of green area (30% of Total plot 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 Group Housing Colony, more than 200 persons will get

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

during post construction phase, more than 300 persons will get marginal employment

opportunities from the residents of Group Housing Colony 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

Dakshin Haryana Bijli Vitran Nigam. The proponents will make arrangements for meeting any

electricity shortage for the project. Therefore, energy resources of the region will not be affected

significantly.

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

with low energy consuming fixtures maximize availability of natural light.

CHAPTER-5

ANALYSIS OF ALTERNATIVES

5.1 INTRODUCTION

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

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

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

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

and environment.

5.2 BUILDING MATERIALS

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

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

environment friendly and recycled/recyclable construction materials.

5.2.1 Wall

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Perforated bricks

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

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 earthquake risk area (Seismic zone- IV). 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 group housing

colony 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.

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 Residential Group Housing Colony

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 Gurgaon 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





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. All essential services such as lifts and water supply will be provided with

power back up.

ii. A security system for the entire group housing 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 exiting neighborhood is

not adversely affected by the project.

While, the site will not act as a thorough fare 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 Group Housing Colony.

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 siting, 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 siting consideration of various group housing

colony 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).

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 Flourescent 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.

CHAPTER-7

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

Residential Group Housing Colony project encompasses the lives of a large number of

people owing to the occupants in case of an accident. It is thus considered necessary to

carry out a risk assessment and disaster management plan of 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;

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:

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

2. Initiate an Emergency Response Team for LPG leakage.

3. Shut down the main valves in the gas bank.

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.

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

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

of the nearest hospitals based on their condition.

Instructions for occupants

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

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

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

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

5. If in a room with a closed door.

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

closed.

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

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

slowly.

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





10. Stay out of damaged buildings.

11. Check that all wiring and utilities are safe.

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

outbreaks. The fire fighting system will consist of portable fire extinguishers, hose reel, wet riser,

yard hydrant, automatic sprinkler system, and manual fire alarm system. The 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 treated water from nearby STP during construction

phase and HUDA supply during operation phase of the project. Given the national water

scenario, where availability if 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 phase will make use of

recycled water from STP of HUDA while water demand for operational phase will be met by

HUDA 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;

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 of 240 KLD & 135 KLD capacity each. 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 group housing 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

efficiency of motors and vehicles through proper maintenance and minimal work at night.

The principles of energy conservation will also be embedded in the buildings through use

of energy efficient fixtures, maximum availability of natural light and use of solar energy

for street lighting.

7.7 RESETTLEMENT AND REHABILITATION

The project will not result in displacement of any local population and hence, does not

require a resettlement and rehabilitation study.

CHAPTER-9

ENVIRONMENTAL MANAGEMENT PLAN

9.1 INTRODUCTION

Identification and prediction of impacts further needs to suggest the mitigative measures which

would play a vital role in prevention of environmental degradation during construction and

operational phase of the Group HousingColony. 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:

Air pollution due to the emission of particulate matter and gaseous pollutants from

operation of D.G.Sets during power failure and vehicular movement;

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.


VillageNangliUmarpur, Chapter IX



9.2.1 Topography and Physiography

During the development, construction and post construction phase of the Group Housing Colony,

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:

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.

Used oil from DG Sets should be stored in HDPE drums in isolated covered facility and

disposed off as per the Hazardous Wastes (Management &Handling) Rules, 1989.

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.

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 by recycled water from STP.

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

Keeping in view the rainfall, storm water drainage system will be developed to carry the runoff.

The storm water disposal 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. Storm water from various buildingsbe connected to

adjacent drain by a pipe through catch basins. Therefore, it has been calculated to provide 14

rainwater harvesting pits at selected locations, which will catch the maximum run-off from the

area.

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

pipe drains is planned adjacent to roads. All building roof water will be brought down

through rain water pipes.

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

intervals for rain water harvesting and ground water recharging.

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

hourly rainfall has been considered as 45 mm/hr. The recharge pit of adequate diameter and

depth is constructed for recharging the water. Inside the recharge pit, a recharge bore is

constructed having adequate diameter and depth. The ground water level in the area is 30-40

meters bgl. 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:


The roof will have smooth, hard and dense surface which is less likely to be damaged

allowing release of material into the water. Roof painting has been avoided since most

paints contain toxic substances and may peel off.

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 sullage would be admitted into the system.

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

the system.

Calculations for storm water load

= 186.986 m3/hr


= 574.986m3/hr


= 143.747 m3

= 56.87 m3/hr

Paved Area = 4,770.12× 0.045 × 0.70

= 150.259 m3/hr


= 543.657m3/hr


= 135.914 m3








As 1 pit/acre is required so, total 14 rain water harvesting pits will be required for 14.025 acre

land.

Total of 14 Rain Water Harvesting pitsare being proposed for artificial rain water recharge

within the project premises.

Figure 9.2: Typical Rain Water Harvesting Pit Design

The rainwater from the terraces and related clean paved areas and the green areas of individual

areas shall be collected in the collection chambers and shall be ultimately connected to the main

storm-water drainage system. The run-off collected from the terraces/ roof area and the green

areas will be diverted to the “Rain Water Harvesting pits” for underground aquifer charging.

Proper “De-silting Chamber” filtration Media and Bye-Pass arrangement shall be prior to

harvesting. Overflow from these wells shall continue into the main drainage system. In the event

of an excessive rain, the discharge will be disposed off outside the site as per local conditions.

Run-off from other paved/ road/ green areas shall be diverted into the underground aquifer

through collection wells and trenches for rainwater harvesting. It is proposed to provide

pretreatment i.e. Grease/ Oil separator etc. as may be the requirement.





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 in all the parking

areas.

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;

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. 200 KLD in Phase-I & 114 KLD in Phase-II

of total sullage. The sullage will be treated in the 2 STPs of 240 & 135 KLD capacity within the

complex and the treated wastewater will be used for flushing, horticultureand rest will be

discharged to nearby land for construction purposes.

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

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 group housing colonyis 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.

Cover scaffolding, hosing down road surfaces and cleaning of vehicles.

On-Road- Inspection for black smoke generating machinery.

Vehicles having pollution under control certificate will be allowed to ply.

Use of covering sheets for trucks to prevent dust dispersion from the trucks.

Reducing the speed of a vehicle to 20 km/hr to reduce emissions on site.

All material storages will be adequately covered and contained.

Training to the workers to reduce idling time of machines that otherwise tends to

produce hydrocarbons ad carbon monoxide.

Best practices for maintenance and repair of all machineries and equipments.


During the post construction phase, following measures will be adopted for pollution control in

the Group Housing Colony:

Adequate stack height for DG Sets

Traffic pollution management

Plantation development

DG Sets:The project will have power back up from 7 nos. of D.G. sets of total capacity 2,780

KVA. There is provision of 4 nos. of DG sets of total capacity of 1,640 KVA (2 X 500 KVA + 2

X 320 KVA) capacity for Part-I and 3 nos. of DG sets of total capacity of 1,140 KVA (3X 380

KVA) capacity forPart-II for power back up in the Group Housing Project. The DG sets will be

equipped with acoustic enclosures to minimize noise generation and adequate stack height for

proper dispersion.





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

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 Group Housing

Colony. Suggested species for plantation are:

Cassia Fistula(Amaltas)

Bauhinia purpurea(Kachnar)

Saracaasoca(Sitaashok)

Jacaranda mimosifolia (Neeligulmohar)

Astoniascholaris (Scholar tree)

Roystoniaregia (Royal palm)

9.2.5 Noise Levels


During the construction phase, some noise will be generated through the operation of

construction machines, excavators, DG sets, etc. Following measures would be taken; into

CHAPTER-10

SUMMARY AND CONCLUSION

10.1 PROJECT BACKGROUND

M/s Emaar MGF Land Ltd. intends to constructtheGroup Housing Colony at Village-

NangliUmarpur, Sector-62, Gurgaon.As per EIA Notification, 2006 & its amendments for all

Group Housingand 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 is1,75,718.12m2. So,

EIA/EMP study is required.The EIA/EMP study has been carried out by Grass Roots Research &

Creation IndiaPvt. 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.

10.2 PROJECT SITE& CONNECTIVITY

The project is located at Village-NangliUmarpur, Sector-62,Gurgaon,Haryana. The project site is

well connected through Sector roads which is adjacent to the project site. The nearest highway is

NH-8 which is 6.64 km away from project site in NW direction. The nearest railway station

BasaiDhankot, about 12 km away from the project site in NW direction. The nearest airport is

Indira Gandhi International Airport, at 16.71 km from the project site in North direction.





10.3 PROJECT FEATURES

The design population of the site is2985. Salient features of the project are:

8. Solid waste generation 1,370.955 kg/day

9. Manpower requirement 150-200 persons

The project will be implemented over a span of two to three years from the commencement of

construction.

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 Irrigation Department,

India Meteorological Department (IMD), Central Ground Water Board, Geological Survey of

India, State Ground Water Department, State Pollution Control Board, Census of India and Local

Forest Department, Non -Governmental Agencies. The baseline status established from analysis

of secondary and primary data and predicted impacts are discussed below. The proposed

mitigation measures are also provided along with.






The land use pattern of the study area is mainly residential, agricultural and open & degraded

vegetation. The site falls under residential land use as per Gurgaon-Manesar Urban Complex,

2021. When awarded to the project proponent, the land was a barren stretch.

The project will be developed as per the provisions of the Gurgaon-Manesar Urban Complex

2021. 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 1,370.955 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-NangliUmarpur, Sector-62, Gurgaon.The water requirement

during construction phase will be met by treated water from nearby STP (HUDA). 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 Plants (STP’s) of capacity 240 & 135 KLDwill be set up to treatwaste water.


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.

Adequate stack heights will be proposed for D.G. Sets of2780 KVAcapacity (2 X 500 KVA + 2

X 320 KVA+3X 380 KVA)above the ground to provide for sufficient dispersion of pollutants.

Water sprinklers will be used to suppress dust during construction. During the operation phase,

green belt and green area development is proposed to restrict and absorb air pollutants.






Noise levels were observed at four locations within the study area. Levels of background noise

monitored in exceed the limits at 55 dB (A) and 45dB (A) for daytime and night time

respectively.

The noise emitted from heavy-duty construction equipments during construction period being

high shall require occupational preventive measures and temporary noise barriers for noise

attenuation. The construction period being about four to five year duration, will require

significant mitigation measures such as restricted loud noise activities to daytime, provision of

PPEs and acoustic enclosures for D.G. Sets.

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 17,027.16m2i.e30% of plot 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

Bambusaarundinacia, Bambusa vulgaris have been proposed to be planted inside the premises.

Parks will also be developed by the project proponent.

List of the plants is given below in Table 10.2.

10.4.6 Socio-economic environment

The group housing colony 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 power supply shall be supplied by DHBVNL (Dakshin Haryana BijliVitaran Nigam

Limited). The demand load for Part-Iwill be 2,105KW and for Part-II it will be 1,252KW. Thus,

the total demand load of the project will be 3,357 KW.The project will have power back up from

7 nos. of D.G. sets of total capacity 2,780 KVA. There is provision of 4 nos. of DG sets of total

capacity of 1,640 KVA (2 X 500 KVA + 2 X 320 KVA) capacity for Part-I and 3 nos. of DG sets

of total capacity of 1,140 KVA (3X 380 KVA) capacity for Part-II for power back up in the

Group Housing Projectare proposed to provide backup in case of power failure.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.

The total estimated cost of the Group Housing Colony is Rs. 480Crores which includes the cost

of the land as well as the developmental cost.

Based on the environmental assessment, the associated potential adverse environmental impacts

can be mitigated to an acceptable level by adequate implementation of the measures as stated in

the EIA and the EMP. Some of the benefits from the project are:

Use of solar energy for street lighting

Provision of green walls and green terraces

Use of CLC blocks (containing approx. 33% flyash)

Use of steel manufactured from recycled content.

Provide permeable paving to control surface water runoff

Rainwater harvesting

Meet all requirements for buildings in moderate earthquake prone areas.

Provision of fire alarms and water sprinklers.

Provision of welfare schemes to workers.

Extending educational and healthcare facilities to the local people.





Commitment to engaging local people and businessmen for maintenance and

repair work.

Hence, it may be concluded that the project will have significant positive economic and social

impact on the local community apart from meeting the housing needs of the occupants, without

bearing any significant adverse environmental impact.
