2.9 Sullage Generation & Treatment It is expected that the project will generate approx. 418 KLD of wastewater. The wastewater will be treated in onsite STP of 875 KL capacity. The treated effluent will be reused for flushing & horticulture. Surplus treated effluent will be discharged to external sewer.

M/S DSS BUILDTECH PVT. LTD. 20 EXPANSION OF GROUP HOUSING PROJECT “THE MELIA” AT VILLAGE MOHAMMADPUR GUJJAR, SECTOR-35, EIA/EMP REPORT SOHNA, DISTRICT GURUGRAM, HARYANA  10% of the waste water that is to be treated is removed from the STP in form of sludge as well as vapors.

 Out of this 10%, approx. 98% of the untreated waste water is removed as wet sludge, which is then dewatered by passing through a filter press and extracted water is added back to the collection chamber of the STP. Somewhat around 40% of the moisture of the sludge is retained, and the sludge thus generated is further processed by drying the same on a non- permeable bed, which upon drying can be used as manure in the green area provided within the project site. The wet sludge is generally removed during the processes of primary treatment, secondary treatment and tertiary treatment or scrubbed off of the collection tank.

 Remaining 2% of waste water is evaporated from the system during treatment process and thus cannot be converted into sewage.

2.10 SEWAGE TREATMENT TECHNOLOGY (MBBR TECHNOLOGY)

MBBR TECHNOLOGY An external sewage network shall collect the sewage from all units, and flow by gravity to the sewage treatment plant. Following are the benefits of providing the Sewage Treatment Plant in the present circumstances:  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 waste water.  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.

Moving bed biofilm reactor technology is based on the principle of attached growth process. Raw sewage will be collected under gravity into the equalization tank after allowing to pass through the bar screen. Screens will be provided in screen chambers and it will be manually cleaned by going down to a platform. The bar screen, by removing coarse solids from the sewage help in protecting the raw sewage pump. Fully submersible centrifugal non clog sewage handling pump will be provided in the collection cum equalization tank to pump the collected waste water to the next MBBR tanks. Automatic level controller will be provided in the tank to turn the pump off at the low water level in the tank and to start the pump when water level is high automatically. Air will be introduced in this tank to prevent any potential foul smell problem & to provide the mixing

M/S DSS BUILDTECH PVT. LTD. 22 EXPANSION OF GROUP HOUSING PROJECT “THE MELIA” AT VILLAGE MOHAMMADPUR GUJJAR, SECTOR-35, EIA/EMP REPORT SOHNA, DISTRICT GURUGRAM, HARYANA of wastewater to avoid the sedimentation of solids in this tank. Air Grid used for aeration purpose shall be non-clog. The sewage collected in equalization tank is pumped the moving bed bioreactor. There shall be two nos. of bioreactors in series for the efficient working and removal of BODs for the required retention time. The process inside the moving bed bioreactors consists of adding small cylindrical-shaped polyethylene/polypropylene carrier elements in aerated basins to support biofilm growth. The small cylinders are provided with a cross inside the cylinder and longitudinal fins on the outside. The biofilm carriers are maintained in the reactor by the use of a perforated plate with appropriate slot at the tank outlet. Air agitation or mixers are applied in a manner to continuously circulate the packing. The packing may fill 25 to 50 percent of the tank volume. Specific surface area of the packing is about 450-500m2/m3 of bulk packing volume. The waste water from first bioreactor flows by gravity through the perforated plate/mesh to the next bioreactor kept in series. Inside the bioreactors, aerobic bacteria grow in an attached growth from around the moving plastic media inside the reactors. The bacteria have to reduce BOD & COD of waste water in the presence of oxygen provided through the air grids located at the bottom of the reactors. The Process does not require any return activated sludge flow or backwashing. From the bio-reactors, the effluent passes by gravity into the clarifier (Tube Settling Tank). Clarifier will be a hopper bottom sedimentation tank provided with appropriate size PVC tube deck media. The suspended solids will settle at the bottom of the tank & clear supernatant will overflow to filter feed tank through outlet launder. The collected sludge at bottom shall be transferred through pumps to sludge holding tank. The clear supernatant after clarifier will be collected in to filter feed tank. This tank will act as housing tank for filter feed pumps. The clarified & dis-infected water will be then fed to filtration unit.

Filtration unit consisting of Dual Media sand filter, activated carbon filter and ultra-filtration system (optional) will remove the residual impurities such as odor/color, suspended solids, BOD/COD. The treated water after the filtration unit will be collected in Irrigation cum

M/S DSS BUILDTECH PVT. LTD. 23 EXPANSION OF GROUP HOUSING PROJECT “THE MELIA” AT VILLAGE MOHAMMADPUR GUJJAR, SECTOR-35, EIA/EMP REPORT SOHNA, DISTRICT GURUGRAM, HARYANA Flushing water storage tank from where it is transferred to flushing water tank at terrace & Irrigation System. Excess sludge from the bottom of the settling tank will be removed and transferred to sludge holding tank. Air grid shall be provided in this tank to avoid conversion into anaerobic conditions, thickening of sludge and keep sludge in homogenous condition. The digested & thickened sludge shall be further thickened through Sludge Dewatering System (Filter press with screw pump) and disposed-off periodically through closed tanker or can be reused as manure.

Figure 2.4: Schematic Diagrams for STP Based on MBBR Technology

2.11 RAINWATER HARVESTING The storm water collection system for the premises shall be self-sufficient to avoid any collection/stagnation and flooding of water. The amount of storm water run-off depends upon many factors such as intensity and duration of precipitation, characteristics of the tributary area and the time required for such flow to reach the drains. The drains shall be located near the carriage way along either side of the roads. Taking the advantage of road camber, the rainfall run off from roads shall flow towards the drains. Storm water from various plots/shall be connected to adjacent drain by a pipe through catch basins. Therefore, it has been calculated to provide 18 rainwater harvesting pits at selected locations, which will catch the maximum run- off from the site.

M/S DSS BUILDTECH PVT. LTD. 24 EXPANSION OF GROUP HOUSING PROJECT “THE MELIA” AT VILLAGE MOHAMMADPUR GUJJAR, SECTOR-35, EIA/EMP REPORT SOHNA, DISTRICT GURUGRAM, HARYANA 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 5 m diameter and 4 m depth is constructed for recharging the water. Inside the recharge pit, a recharge bore is constructed having adequate diameter and depth. 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.

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, 6 (six) monitoring stations were set up. Table - 3.2 gives location of the ambient air quality monitoring stations and a map showing the ambient air quality monitoring stations is attached as Annexure - XXVII.

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

METHODS OF SAMPLING AND ANALYSIS The brief methodology of the parameter analyzed is as follows: I. Particulate Matter (PM2.5): (CPCB Method) Particulate Matter (PM2.5) was analyzed by Fine particulate Sampler Enviro tech Model APM 550. PM 2.5 was collected on 47mm diameter filter paper. The mass concentration of (PM2.5) fine particles in ambient air was calculated as the total mass of collected particles divided by the volume of air sampled. II. Particulate Matter (PM10): Particulate Matter (PM10) was carried out by respirable dust sampler enviro tech Model APM 460 BL. The cyclone of this instrument is used for fractionating the dust into two fractions. PM 10 dust is accumulated on the filter paper (8ʺ×10ʺ size) while coarse dust is collected in a cup placed under the cyclone.PM 10 was calculated as per IS: 5182 (Part 23):2006. The mass of these particles was determined by the difference in filter weight prior to and after sampling. The concentration of PM 10 in the designated size range was calculated by dividing the weight gain of the filter by the volume of air sampled. III. Sulphur dioxide (SO2): SO2 was monitored with the help of APM 411 assembly attached with APM 460 BL using the impinge. It was absorbed by aspirating a measured air sample through a solution of Potassium tetrachloromercurate (TCM). This procedure resulted in the formation of a dichloro sulphite mercurate complex. The complex was made to react with pararosaniline and methylsulphonic acid. The absorbance of the solution was measured by means of spectrophotometer.

IV. Nitrogen Dioxides: NO2 was monitored with the help of APM 411 assembly attached with APM 460 BL using the impinge. It was collected by bubbling air through a solution of sodium hydroxide and sodium arsenite. The concentration of nitrite ion produced during sampling was determined colorimetrically by reacting with the nitrite ion with phosphoric acid, sulphanilamide and NEDA and absorbance of highly colored azo-dye was measured at 540nm. V. Carbon Monoxide: It is measured using CO Analyser. 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. CO was monitored on hourly basis whereas other parameters were monitored on 24 hourly bases.

EXPANSION OF GROUP HOUSING PROJECT “THE MELIA” AT VILLAGE MOHAMMADPUR GUJJAR, SECTOR-35, EIA/EMP REPORT SOHNA, DISTRICT GURUGRAM, HARYANA 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 4 locations, which covers residential areas, and silence area within 6 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 MoEFCC dated December 14, 2000 on ambient air quality standards has different noise levels for different zones viz. project site, industrial, and residential zones. Four sampling locations were selected for the sampling of noise levels. The sampling locations are given in Table - 3.4 below.

3.4.5 DRAINAGE The drainage of the Gurgaon district is typical of the arid and semi-arid areas. It comprises of large depressions and streams. The drainage is peculiarly complex owing to most of the streams tending to converge towards inland depressions instead of flowing into Yamuna. The important depressions in the level of the district in this region are Khalipur, Chandaini, Sangel-Ujina, Kotla Dahar Jheels and Najafgarh Lake. Sahibi and Indrani are two important seasonal streams of the district.

3.5 Biological Environment

3.5.0 Introduction

Biodiversity reflects the potential of a regional ecosystem. Biota of a particular area is considered as indicators of the environment as they quickly respond not only to one environmental factor but also an interactive group of factors. These communities influence and react sensitively to changes in the balance of environmental stresses.

Biological diversity comprises the variability of genus, species and ecosystems and is very crucial for maintaining the basic processes on which the life depends. On the basis of biological physiology biodiversity broadly can be divided into two category i.e. the floral diversity and faunal diversity. Conservation of the biodiversity is essential for the sustainable development as it not only provides the food, fodder and medicine, but also contributes to improvement of essential environmental attributes like air, water, soil, etc. Before starting any Environmental Impact Assessment study, it is necessary to identify the baseline of relevant environmental parameters which are likely to be affected as a result of the operation of the proposed project. A similar approach has been adopted for conducting the study on Biological Environment for this Project. Both terrestrial and aquatic ecosystems have been studied to understand the biological environment near the project site.

The study was conducted in the project area to assess all possible consequences on the biological environment. Flora and fauna surveys and data collection conducted for assessing the biological diversity and its status over a period of time that forms an integral part of Impact Assessment Techniques. The present study is highlighting the various issues pertaining to floristic diversity and the faunal wealth in the core area i.e. Expansion of Group Housing Project at Village –Mohammadpur Gujjar, Sector- 35, Sohna, Gurgaon, Haryana and buffer zone i.e. area within 10 km radius.

4.1 INTRODUCTION This chapter discusses identification and appraisal of various environmental impacts due to the proposed Project. Generally, the environmental impacts can be categorized as either primary or secondary. The development, construction and functional phase of the project comprise various activities, each of which may have some impact on environmental parameter. Various impacts during the development, construction and operation phase on the environmental parameters have been studied to estimate the impact on environment.

The project will be constructed and developed gradually in the time span of 3-4 years (approx.). For proper evaluation and assessment of the environmental impacts due to development, construction and functional phase of project understanding to the various activities associated with the project is essential. Various activities related to the project would be different, in terms of nature during the development, construction and operational phase.

The impact identification and prediction process aims to:  Identify potential source or cause of impact throughout life of the 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, 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.

4.5 ASSESSMENT OF ENVIRONMENTAL IMPACTS DURING DEVELOPMENT AND CONSTRUCTION PHASE

4.5.1 Topography Impact: Topography around the project site is almost plain. Therefore, existing topography and physiography of the area will not be affected during construction and operation phase of the project.

Mitigation Measure: It is further proposed to maintain 20,494.66 m2 area as green through plantation of various local and aesthetic species to improve the vegetation covers of the area. It is however proposed that apart from the proposed plantation greens, turfing with local species will be carried out. Therefore, there is no significant impact on topography from the project.

4.5.2 Land Use Pattern Impact: No significant impact is expected from the project which will be constructed after obtaining all necessary permissions.

4.5.3 Land Environment Impact: Soil would be excavated at project site for laying foundation of building. During the disposal of redundant overburden, soil of filling area would be covered and lost permanently.

Mitigation: The soil is being excavating during construction and first temporarily stored in an area earmarked and then will be used to fill up low lying area in and around the project site and

M/S DSS BUILDTECH PVT. LTD. 90

EXPANSION OF GROUP HOUSING PROJECT “THE MELIA” AT VILLAGE MOHAMMADPUR GUJJAR, SECTOR-35, EIA/EMP REPORT SOHNA, DISTRICT GURUGRAM, HARYANA rest of the soil will be transported by road to fill up low lying areas elsewhere. Proper drainage system will 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. 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 Surface Water Quality Impact: The primary concerns relating to surface water quality associated with construction activities are pointed out below:  Runoff related to unpaved and excavated areas during the rain.  Sediments transported to runoff from the construction site.  Run off related to area where lubricant, fuel other materials are stored, used and disposed, off. Surface water quality may be affected with the discharge of the runoff from the project site. The impact to the surface water bodies could arise from the increased soil erosion from excavated site only causing increase in the suspended particles and turbidity of runoff water from the site. However, this impact will be temporary in the nature and would be observed in first rain only and as soon as rain is over excavated soil at site would be stabilized. Therefore, the surface water quality during rains will be impacted marginally for very short duration.

Mitigation Measures: During the construction phase, surface water quality is likely to be affected due to soil erosion during first rain and generation of sullage mainly from construction labour camp. However, this phenomenon will be temporary and restricted to close vicinity of construction site. The impact on surface water quality can be minimized by adopting following measures;

M/S DSS BUILDTECH PVT. LTD. 91

EXPANSION OF GROUP HOUSING PROJECT “THE MELIA” AT VILLAGE MOHAMMADPUR GUJJAR, SECTOR-35, EIA/EMP REPORT SOHNA, DISTRICT GURUGRAM, HARYANA

 Excavation during dry season and proper management of excavated soils,  Clearing all debris from site as soon as construction is over.  By providing proper hutment and toilet facilities for construction labour,  Proper disposal of wastewater.

4.5.4.2 Ground water Quality Impact: No hazardous chemical and material will be used in the development and construction phase of the project. Debris and waste generated 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.

4.5.4.3 Surface and Ground Water Hydrology Surface Water Hydrology Impact: The project site is outside flood plain. Runoff during rain takes way to natural drain and in storm water drains laid in the area. During construction phase, there is no impact anticipated on the drainage pattern of the project area.

Mitigation Measures: Project proponent will ensure no interception on water runoff flow routes and drainage pattern of the area throughout the construction of the project by providing adequate water channel.

Ground Water Hydrology Impact: Water requirement during construction phase will be met from STP treated effluent of HUDA/private water tankers. Water will be required for site preparation activities dust settlement, consolidation, compaction and curing as well as building construction and drinking

M/S DSS BUILDTECH PVT. LTD. 92

EXPANSION OF GROUP HOUSING PROJECT “THE MELIA” AT VILLAGE MOHAMMADPUR GUJJAR, SECTOR-35, EIA/EMP REPORT SOHNA, DISTRICT GURUGRAM, HARYANA water requirement. The requirement of construction water will not put sudden pressure on the available ground water resources of area. Therefore, impact on ground water resources will be insignificant during construction of the project.

Mitigation Measures: Although no significant impact is anticipated on the groundwater regime, it is proposed to carry out the following to further minimize the demand on freshwater resources:  Curing water will be sprayed on concrete structures and free flow of water not allowed.  After liberal curing on the first day, all concrete structures will be painted with curing chemical to save water to stop daily water curing hence save water.  Concrete structures will be covered with thick cloth/gunny bags and then water sprayed on them to avoid water rebound and ensure sustained and complete curing.  Ponds will be made using cement and sand mortar to avoid water flowing away from the flat surface while curing.  Water ponding will be done on all sunken slabs. This will also highlight the importance of having an impervious formwork.

4.5.5 Air Environment Emissions Source: The potential sources of air emissions during the construction and development phase of the project will be as follows:  Dust from earth works (during site clearance and preparation);  Emissions from power generator at site;  Emissions from the operation of construction equipment and machines;  Fugitive emissions from vehicles running to site;  Fugitive emissions during the unloading of material at the site;  Fugitive 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 matter, etc.

M/S DSS BUILDTECH PVT. LTD. 93

EXPANSION OF GROUP HOUSING PROJECT “THE MELIA” AT VILLAGE MOHAMMADPUR GUJJAR, SECTOR-35, EIA/EMP REPORT SOHNA, DISTRICT GURUGRAM, HARYANA

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 on-site 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 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, loading & unloading activities.  Generation of noise from excavation machines, concrete mixer and other construction machines,  Generation of noise during the operation of D.G. Set  Generation of noise during concreting, hammering, etc.

All the above-mentioned sources of development and construction activities at Project would be intermittent and experienced occasionally. It may also be noted that the most of the construction activities would be carried out only during the daytime. The expected noise levels from various activities are given hereunder: From vehicles bringing materials to the site 70 dB (A) 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: (Lpl/10) (Lp2/10) (Lp3/10) Lp (total) = 10 log (10 + 10 + 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, 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

M/S DSS BUILDTECH PVT. LTD. 95

EXPANSION OF GROUP HOUSING PROJECT “THE MELIA” AT VILLAGE MOHAMMADPUR GUJJAR, SECTOR-35, EIA/EMP REPORT SOHNA, DISTRICT GURUGRAM, HARYANA 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:

Lr2 = Lr1 - 20 log (r2) – 8 ………. ( 2 )

Also, Lr2 = Lr1 - 20 log (r2/ r1)

Where: Lr1 and Lr2 – Sound Pressure Level (SPLs) at points located at 1m from 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 within short distance. Baseline noise level at the project site has been given in Table 4.4. Table 4.4 (a): Noise Levels in the Study Area(March –April 2015)

* Day time (6.00AM TO 10.00PM) ** Night time (10.00PM TO 6.00AM)

The noise produced during development and construction phase will have temporary impacts on the existing, ambient noise levels at project site but restricted to limited distance 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 project. No tree felling is involved, as the site is devoid of vegetation.

Birds and other domesticated biodiversity observed near the project site are common and already adapted to thrive in human - colonized habitats. The project will not have any major negative ecological impact. There is no forest near the project site and therefore there will be no effect on the ecology of the area.

Mitigation Measures: However, it is to develop extensive green areas in the project site to improve the aesthetics of the area which will also help in reduction of air pollution, noise pollution and provide suitable habitat for local birds and animal species.

M/S DSS BUILDTECH PVT. LTD. 97

EXPANSION OF GROUP HOUSING PROJECT “THE MELIA” AT VILLAGE MOHAMMADPUR GUJJAR, SECTOR-35, EIA/EMP REPORT SOHNA, DISTRICT GURUGRAM, HARYANA

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 3-4 years as workers make everyday purchases from local traders in nearby 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 the project. Once the development and construction 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 due to the project. Therefore, an overall positive impact is anticipated on economy of the area due to the proposed project.

4.5.9 Socio-Economic During the development and construction of Expansion of Group Housing Project “The Melia”, about 800-850 skilled and semiskilled and unskilled workers will get direct employment opportunity, which will have beneficial impact on the local people and improve socio-economic condition 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 the project will be developed gradually in the time span of about 3-4 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.

M/S DSS BUILDTECH PVT. LTD. 98

EXPANSION OF GROUP HOUSING PROJECT “THE MELIA” AT VILLAGE MOHAMMADPUR GUJJAR, SECTOR-35, EIA/EMP REPORT SOHNA, DISTRICT GURUGRAM, HARYANA

Other safety precautions to be maintained at work site including provision of PPEs, guarding of dangerous machine parts, maintenance of equipment 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 will 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, 2016.

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. Expansion of Group Housing Project “The Melia” 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

M/S DSS BUILDTECH PVT. LTD. 99

EXPANSION OF GROUP HOUSING PROJECT “THE MELIA” AT VILLAGE MOHAMMADPUR GUJJAR, SECTOR-35, EIA/EMP REPORT SOHNA, DISTRICT GURUGRAM, HARYANA adversely affect the local traffic pattern since the site is well connected via wide roads and present traffic load on these road is 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 will also be ensured that all the vehicles to the site will be provided with Parking space such that there is no waiting time along the access roads.

4.6 ASSESSMENT OF THE ENVIRONMENTAL IMPACTS DURING OPERATION PHASE 4.6.1 Land Environment Impact: During the operation phase of the project, the soil may get polluted/ contaminated from littering of various kinds of wastes generated within the site such as food items, paper, wood pieces, paints, pesticides, oil & grease etc. However, as a result of the proposed solid waste management plan, 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 will 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 operation 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

M/S DSS BUILDTECH PVT. LTD. 100

EXPANSION OF GROUP HOUSING PROJECT “THE MELIA” AT VILLAGE MOHAMMADPUR GUJJAR, SECTOR-35, EIA/EMP REPORT SOHNA, DISTRICT GURUGRAM, HARYANA water reused within the site thereafter. Therefore, impact on the surface water hydrology will be insignificant during the operation 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 storm water management system of the city but also recharge groundwater.

4.6.2.2 Ground water hydrology Impact: During operation phase, the total water requirement of the Expansion of Group Housing Project “The Melia” is approx. 707 KLD out of which domestic water requirement is 563 KLD. The fresh water demand will be approx. 414KLD. The water requirement will be met from HUDA. Therefore, no impact is anticipated on ground water resources due to project.

To enhance the ground water level around the project site the rain water harvesting will be proposed. The rainwater harvesting will recharge groundwater aquifers from the open areas as well as roof top of the buildings. Treated water from the site will be recycled for landscaping, flushing and to water body.

Water meters conforming to ISO standards will 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 effluents generated from the Expansion of Group Housing Project “The Melia” will be collected through the sewer line network provided in our Project, and treated in onsite STP of 1 onsite STP of total capacity 875 KL that will generate 376 KLD of treated effluent which will be reused for flushing and horticulture.

M/S DSS BUILDTECH PVT. LTD. 101

EXPANSION OF GROUP HOUSING PROJECT “THE MELIA” AT VILLAGE MOHAMMADPUR GUJJAR, SECTOR-35, EIA/EMP REPORT SOHNA, DISTRICT GURUGRAM, HARYANA

It is expected that the project after Expansion will generate approx. 418 KLD of sullage. Surplus treated effluent will be discharged to external sewer line.

Mitigation Measures: As no impact is anticipated on the surface 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 collected 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 project site will be maintained well. Solid waste management practices will be adopted and followed to prevent groundwater pollution from rain water harvesting.

4.6.3 Air Environment Prediction of Impacts Vehicular emissions and DG sets emission will be major sources of air pollution from building construction projects. Ground Level Concentration of pollutants (as added by the project) will depend upon the following:  Emission of pollutants from additional traffic on the roads due to the project.  Meteorological conditions.  Emission sources from D.G. Sets.

PM, NO2, SO2 and CO will be the main pollutants of primary concern released from traffic movement and DG sets. Assuming that under cross wind condition perpendicular to the road, the dispersion of vehicular emissions would be confined within limited distance from the road and concentration will decrease with the increase in distance from road. It was anticipated that the

M/S DSS BUILDTECH PVT. LTD. 102

EXPANSION OF GROUP HOUSING PROJECT “THE MELIA” AT VILLAGE MOHAMMADPUR GUJJAR, SECTOR-35, EIA/EMP REPORT SOHNA, DISTRICT GURUGRAM, HARYANA contribution of vehicular emissions from the exhaust in ambient air quality will be marginal as Pollution under Control (PUC) Certified vehicles and branded make operated vehicle with low sulphur diesel will be used. Ground Level Concentration (GLC) of pollutants is found to be well within the stipulated National Ambient Air Quality Standards due to traffic movement and vehicles used inside the premises. DG sets will be main source of Air Pollution in the project. CPCB/ MoEF & CC approved USEPA dispersion model -ISCST3 was used for prediction of impacts caused by DG sets. Stack & emission data was used as per design value provided by standard make and stipulated standards. Other primary data used as input for model were hourly meteorological data of Wind speed, direction, temperature, cloud amount and mixing height. Mixing height used in the model was taken from secondary data source “Atlas of Hourly Mixing Height Assimilative Capacity of Atmosphere in India published in 2008 by IMD, Delhi”. Hourly meteorological monitored at site during study period data was compared with long term data available from the nearest India Meteorological station or any other authorized source/Govt. agencies.

In this project, total 2 no. of D.G. set of total capacity 1635 kVA (1 x 1010 kVA & 1 x 625 kVA) have been proposed, for back up of electricity supply during power failure.

This will cause emission of PM, SO2, NO2 and CO in the Ambient Air Quality. In the project D.G. sets will be used only during power failure and low sulphur diesel will be used as fuel to minimize SO2 emission. Therefore, incremental load in the ambient air environment will be very low as given in the report. An adequate stack height of D.G. sets will be provided as per the stipulated guidelines of Central Pollution Control Board (CPCB)/ National Building Code Manual to facilitate proper dispersion of pollutants and to minimize the impact on Ambient Air Quality under the influence of local meteorology.

Meteorology – Hourly Meteorological data of wind speed & direction, temperature, cloud amount and rainfall were monitored at site for 5 month for the dispersion model. Wind rose (Figure - 4.1) was prepared in sixteen directions as per standards. It was observed that westerly and southwesterly was prevalent wind during the study period.

Figure 4.1: The wind-rose diagram based on the study period

Model details and Frame work of Computation: The predictions for air quality during operation phase were carried using CPCB/MoEF & CC approved “USEPA, Industrial Source Complex (Version - ISCST3)” Dispersion model developed by the US Environmental Protection Agency (USEPA) for prediction of pollutants dispersion from single or multiple point sources using emission and hourly meteorological data of the study period. Assumption used in the model was as follows:

 The plume rise is limited to that of the mixing layer as published by IMD in the Catalogue of Atlas of Mixing Heights in India for the site  Stack down-wash is not considered.  Flat terrain is used for computations;  It is assumed that the pollutants do not undergo any Physico-chemical transformation.  Chemical and scavenging process occurred in the atmosphere in the pollutants released at the stack exit is not considered.

M/S DSS BUILDTECH PVT. LTD. 104

EXPANSION OF GROUP HOUSING PROJECT “THE MELIA” AT VILLAGE MOHAMMADPUR GUJJAR, SECTOR-35, EIA/EMP REPORT SOHNA, DISTRICT GURUGRAM, HARYANA

 Prediction is based on single/multiple point sources, pollution released at stack exit and dispersed on the ground under influence of local meteorological conditions during the season. ISCST3 dispersion model was used to predict GLC caused by a single point source at each receptor of 40 m x 40 m of grid network covering total area of 2000 m x 2000m around the proposed source with stack & emission values and 1-hourly meteorological data. It was observed that SO2, NO2, Co and PM were significant pollutants released from the fuel of the

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

NO2. In this project, NO2 was the worst affected pollutant released into the atmosphere (Table 4.5) with high emission value.

Mitigation Measures: The project proponent will develop a green belt inside the premises of the project site and along the internal road, which will work as barrier for the movement of pollutants and help in pollution control.

4.6.4 Noise Environment

Impact: The main sources of noise from the project are running of D.G. Sets and vehicular traffic. D.G. Sets will provide emergency electricity supply during power failure. This will be intermittent and for short durations. The vehicles playing within the site will be mainly of the residents and are hence not expected to cause unnecessary noise. Hence, during this phase, no major impact on noise environment is anticipated.

Mitigation Measures: D.G. Sets will be fitted in acoustic enclosures to control the noise generated within 25 dB (A) insertion loss or for meeting the ambient noise standard whichever is on higher side as per E (P) Act, GSR 371 (E) and its amendments. Adequate personnel protective equipment (PPE) will be provided. The traffic noise will diminish within a short distance from the source of origin. Honking within the site will be discouraged. Proposed green belt plantation will further restrict the noise.

EXPANSION OF GROUP HOUSING PROJECT “THE MELIA” AT VILLAGE MOHAMMADPUR GUJJAR, SECTOR-35, EIA/EMP REPORT SOHNA, DISTRICT GURUGRAM, HARYANA

4.6.5 Terrestrial Ecology Impact: The project proposes 20,494.66 m2 (30.17 % of plot area) of green 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, 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 the project, approx. 13000 persons will get employment opportunities. As an estimate, during operation phase, more than 300 persons will get marginal employment opportunities. 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 site 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.

M/S DSS BUILDTECH PVT. LTD. 106

EXPANSION OF GROUP HOUSING PROJECT “THE MELIA” AT VILLAGE MOHAMMADPUR GUJJAR, SECTOR-35, EIA/EMP REPORT SOHNA, DISTRICT GURUGRAM, HARYANA

Mitigation Measures: As per the planning, entry and exit will occur through service road. Internal roads have been designed as per NBC and local regulations for smooth traffic circulation.

4.6.8 Energy Resources Impact: During the operation phase of the project, electric supply will be provided from D.G set and Dakshin Haryana Bijli Vitran Nigam.

Mitigation Measures: To promote energy conservation, it is proposed to provide the buildings with low energy consuming fixtures and maximize availability of natural light.

EXPANSION OF GROUP HOUSING PROJECT “THE MELIA” AT VILLAGE MOHAMMADPUR GUJJAR, SECTOR-35, EIA/EMP REPORT SOHNA, DISTRICT GURUGRAM, HARYANA 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 manufacture of building materials should also be assessed to ensure the use of environment friendly and recycled/ recyclable construction material.

5.2.1 Wall Conventionally, sun burnt clay bricks are cemented in 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 – 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 aluminum 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

M/S DSS BUILDTECH PVT. LTD. 108

EXPANSION OF GROUP HOUSING PROJECT “THE MELIA” AT VILLAGE MOHAMMADPUR GUJJAR, SECTOR-35, EIA/EMP REPORT SOHNA, DISTRICT GURUGRAM, HARYANA  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. 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 will be met by steel and aluminum.  Problem with RCC. The choice of cement will be:

M/S DSS BUILDTECH PVT. LTD. 109

EXPANSION OF GROUP HOUSING PROJECT “THE MELIA” AT VILLAGE MOHAMMADPUR GUJJAR, SECTOR-35, EIA/EMP REPORT SOHNA, DISTRICT GURUGRAM, HARYANA  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 cementation 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 is located in high 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.

EXPANSION OF GROUP HOUSING PROJECT “THE MELIA” AT VILLAGE MOHAMMADPUR GUJJAR, SECTOR-35, EIA/EMP REPORT SOHNA, DISTRICT GURUGRAM, HARYANA 5.4 GREEN BUILDING M/s DSS Buildtech Pvt. Ltd, proposes to design and construct the project in line with the requirements of Green Building. 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 will 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 project such that there is no alteration in the 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 waste, etc. The project proponent is also committed towards conservation of water. This includes use of treated water, 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 treated effluent within the site.

M/S DSS BUILDTECH PVT. LTD. 111

EXPANSION OF GROUP HOUSING PROJECT “THE MELIA” AT VILLAGE MOHAMMADPUR GUJJAR, SECTOR-35, EIA/EMP REPORT SOHNA, DISTRICT GURUGRAM, HARYANA 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 conservation. An important means for achieving this is spreading awareness to the occupants for water conservation. To reduce the freshwater demand of the project, waste water from site will be treated in a STP and treated effluent will be reused for landscaping, flushing and DG cooling. d. Use of Energy Efficient design and Eco-Friendly Equipment The project will be designed such that there is optimal solar energy utilization, especially 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 operation stages.

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 area 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. e. 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 source 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

M/S DSS BUILDTECH PVT. LTD. 112

EXPANSION OF GROUP HOUSING PROJECT “THE MELIA” AT VILLAGE MOHAMMADPUR GUJJAR, SECTOR-35, EIA/EMP REPORT SOHNA, DISTRICT GURUGRAM, HARYANA 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.

f. Effective Controls and Management Systems It is proposed to establish a Management System that will comprise modern equipment 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 project will be provided comprising intercom facility, closed circuit camera to the entrance and round-the-clock manning. iii. Separate entry and exits are proposed. The staffs’ vehicle will be provided with identification stickers while visitors’ vehicles will be monitored through security guards at the entrance/exit.

The project proponent further proposes extensive green areas as avenues, parks and roadside plantation. The plants serve to provide positive environmental impacts such as reduction in overall energy use in buildings.

5.5 COMMUNITY ISSUES All efforts will be made to ensure that the exiting neighborhood is not adversely affected by the project.

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, 2017 in the building structure.

The concept of passive solar design emphasizes architectural design 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 citing consideration various components of Expansion of Group Housing Project “The Melia” to optimize availability of natural sunlight. Advanced Solar Passive Techniques are employed to achieve energy efficiency.  Glazed windows are proposed. 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 LED lamps instead of GLS lamps Expansion of Group Housing Project “The Melia”. • Use of LED instead of GLS lamps for Common area. • T5 lamps are used instead of Normal Fluorescent lamps in Basements

M/S DSS BUILDTECH PVT. LTD. 114

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 will be no parking on the external 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 project site Adequate parking is proposed within the project site. Wide internal roads are proposed as per norms. To achieve the speed limit, speed humps will be provided.

7.0 INTRODUCTION This chapter broadly looks at various aspects related to disaster management, resource conservation and resettlement issues.

7.1 RISK ASSESSMENT AND DISASTER MANAGEMENT PLAN The project will encompass the lives of a large number of people. It will also involve installation of various structures and machineries that meet the comfort and needs of its residents but may also pose serious threat in case of an accident. It is thus considered necessary to carry out a risk assessment and disaster management plan for the project.

7.1.1 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.

EXPANSION OF GROUP HOUSING PROJECT “THE MELIA” AT VILLAGE MOHAMMADPUR GUJJAR, SECTOR-35, EIA/EMP REPORT SOHNA, DISTRICT GURUGRAM, HARYANA A state of the art firefighting system is proposed for the project to prevent and control fire outbreaks. The firefighting system will consist of portable fire extinguishers, hose reel, wet riser, yard hydrant, automatic sprinkler system, and manual fire alarm system. The Expansion of Group Housing Project “The Melia” buildings will also be provided with automatic fire detection and alarm system.

7.5 RESOURCE CONSERVATION The project will lead to utilization of various natural resources. As an environmentally responsible corporate, the developer will endeavor to conserve these resources by judicious management and recycling and strive to build up these resources where possible.

No withdrawal of groundwater: The water during operational phase will be sourced from HUDA. 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;  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;

M/S DSS BUILDTECH PVT. LTD. 128

EXPANSION OF GROUP HOUSING PROJECT “THE MELIA” AT VILLAGE MOHAMMADPUR GUJJAR, SECTOR-35, EIA/EMP REPORT SOHNA, DISTRICT GURUGRAM, HARYANA  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 wastewater generated from the sites will be treated in on-site Sewage Treatment Plant. This will enable the treated wastewater to be used for flushing and landscaping thereby reducing the requirement of freshwater for these purposes.

Rainwater harvesting: The increased hard surface as a result of the project will increase the runoff as compared to an 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: The project will require various kinds of natural construction minerals 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 nearby construction sites, as per demand or sold to local vendors. 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

9.1 INTRODUCTION Identification and prediction of impacts further needs to suggest the mitigation measures which would play a vital role in prevention of environmental degradation during construction and operational phase of the project. This leads to preparation of Environmental Management Plan (EMP), therefore EMP forms an imperative part of EIA process.

The Environmental Management plan is a site specific plan developed to ensure that the project is implemented in an environmentally sustainable manner where all contractors and subcontractors, including consultants if any, understand the potential environmental risks arising from the project and take appropriate actions to minimize those risks. EMP also ensures that the project implementation is carried out in accordance with the planned design and by taking appropriate mitigates actions to reduce adverse environmental impacts during project’s life cycle. The project is being created 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 as 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.  Wastewater 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.

M/S DSS BUILDTECH PVT. LTD. 132 EXPANSION OF GROUP HOUSING PROJECT “THE MELIA” AT VILLAGE MOHAMMADPUR GUJJAR, SECTOR-35, EIA/EMP REPORT SOHNA, DISTRICT GURUGRAM, HARYANA To ensure better environment in & around the project site, effective EMP needs to be developed separately for construction and operational phase.

9.2 ENVIRONMENTAL MANAGEMENT STRATEGIES Strategy for environmental management in construction work is based on three-pronged approach comprising of:  Pollution prevention.  Pollution control.  Protection of pollution recipients.

9.2.1 Topography and Physiography During the development, construction and operation phase of the project, no significant impact is anticipated on local or regional topography and Physiography, hence exhaustive management plan is not required.

9.2.2 Soil Development & Construction Phase During the construction phase, various kinds of wastes are generated that is being disposed in varied ways. The following measures are being taken to prevent soil contamination at site and ensure waste management:

Vegetation and top soil management:  Remove vegetative cover only from the specific area on which construction is being take place.  Plantation as proposed will be started at the earliest.  The top soil has been stripped from constructional areas and stockpiled for later reuse in landscaping.  Promote use of organic fertilizers.  Construction of erosion prevention troughs, as deemed necessary.

M/S DSS BUILDTECH PVT. LTD. 133 EXPANSION OF GROUP HOUSING PROJECT “THE MELIA” AT VILLAGE MOHAMMADPUR GUJJAR, SECTOR-35, EIA/EMP REPORT SOHNA, DISTRICT GURUGRAM, HARYANA  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 is being 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 have been collected from site as soon as particular construction activity is over.  During construction of flexible pavement, bitumen wastes is being collected (if any) and disposed in environmentally sound manner.  The number, frequency and area of movement of heavy machinery are also restricted.  Recycling of construction wastes into aggregates for use in the project site.  Used oil from DG Sets is being stored in HDPE drums in isolated covered facility and disposed-off as per the Hazardous Wastes (Management & Handling) Rules, and its amendments 2016.  Wastes from the labour camps will be collected and disposed as per the existing practices in the site.

Operation 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 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.

M/S DSS BUILDTECH PVT. LTD. 134 EXPANSION OF GROUP HOUSING PROJECT “THE MELIA” AT VILLAGE MOHAMMADPUR GUJJAR, SECTOR-35, EIA/EMP REPORT SOHNA, DISTRICT GURUGRAM, HARYANA  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, vehicle will be covered to avoid littering.

Disposal Non-recyclable and non-biodegradable waste will be disposed through local approved agency. The biodegradable waste will be converted to manure through Organic Waste Converter. SWM Plan for Operation phase is shown below:

Figure 9.1 Solid Waste Management Flow Diagram (Operation Phase)

A local vendor will be hired for solid waste management during Operation Phase.

9.2.3 Hydrology Ground Water Development & Construction Phase The water requirement during the construction phase will met from recycled water from STP of HUDA. The following are also proposed to further reduce the demand of water:  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 are being covered with thick cloth/gunny bags and then water sprayed on them to avoid water rebound and ensure sustained and complete curing.  Pools have been made using cement and sand mortar to avoid water flowing away from the flat surface while curing.  Water ponding has been done on all sunken slabs. This has also highlighted 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.

Water Resource Development

The storm water collection system for the premises shall be self-sufficient to avoid any collection/stagnation and flooding of water. The amount of storm water run-off depends upon many factors such as intensity and duration of precipitation, characteristics of the tributary area

M/S DSS BUILDTECH PVT. LTD. 136 EXPANSION OF GROUP HOUSING PROJECT “THE MELIA” AT VILLAGE MOHAMMADPUR GUJJAR, SECTOR-35, EIA/EMP REPORT SOHNA, DISTRICT GURUGRAM, HARYANA 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 plots/shall be connected to adjacent drain by a pipe through catch basins. Therefore, it has been calculated to provide 18 rainwater harvesting pits at selected locations, which will catch the maximum run- off from the site. 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 5 m diameter and 4 m depth is constructed for recharging the water. Inside the recharge pit, a recharge bore is constructed having adequate diameter and depth. 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

M/S DSS BUILDTECH PVT. LTD. 137 EXPANSION OF GROUP HOUSING PROJECT “THE MELIA” AT VILLAGE MOHAMMADPUR GUJJAR, SECTOR-35, EIA/EMP REPORT SOHNA, DISTRICT GURUGRAM, HARYANA 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:

Net Plot Area = 67,915.15m2

Roof-top area = Ground Coverage = 11,806.21m2 Green Area = 20,494.66 m2

Paved Area = Plot Area – (Roof-top Area + Green Area) = 67,915.15 – (11,806.21 + 20,494.66) = 67,915.15 – 32,300.87 = 35,614.28m2

Roof-top area = 67,915.15 × 0.045 × 0.90 = 2750.56 m3/hr

Green Area = 20,494.66 × 0.045 × 0.20 = 184.45m3/hr

M/S DSS BUILDTECH PVT. LTD. 138 EXPANSION OF GROUP HOUSING PROJECT “THE MELIA” AT VILLAGE MOHAMMADPUR GUJJAR, SECTOR-35, EIA/EMP REPORT SOHNA, DISTRICT GURUGRAM, HARYANA Paved Area = 35,614.28 × 0.045 × 0.70 = 1121.84m3/hr

Total Runoff Load = 2750.56 + 184.45 + 1121.84 = 4056.85m3/hr

Taking 20 minutes retention time, volume of storm water = 4056.85/3 = 1352.28 m3 Capacity of Recharge pit = π r2h = 3.14 × 2.5 × 2.5 × 4 = 78.5 m3

Hence No. of pits required = 1352.28/78.5 = 17.22 pits/18 pits

Total of 18 Rain Water Harvesting pits are proposed for artificial ground water recharge.

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 will be carried out. Use of fertilizers and pesticides will be avoided prior to and during monsoons. Clarifiers or oil/ water separators will also be installed.

Minimal Water Consumption To reduce the water consumption, awareness along the following lines will be spread amongst the management and maintenance team:  Installation of water meters conforming to ISO standards at inlet and outlet point of water supply.  To further lower the water consumption, options of Low flow flushing systems, sensor based fixtures, and tap aerators etc. will be explored.  Leak detection  Drip irrigation for shrubs and trees  Use of low-volume, low-angle sprinklers for lawn areas The message of water conservation will be spread amongst the residents through awareness campaigns and pamphlets. Following tips will 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 effluent It is expected that the project will generate approx. 418 KLD of wastewater. The wastewater will be treated in onsite STP of 505 KL capacity. The treated effluent will be reused for flushing & horticulture. Surplus treated effluent will be discharged to external sewer.

 10% of the waste water that is to be treated is removed from the STP in form of sludge as well as vapors.

 Out of this 10%, approx. 98% of the untreated waste water is removed as wet sludge, which is then dewatered by passing through a filter press and extracted water is added back to the collection chamber of the STP. Somewhat around 40% of the moisture of the sludge is retained, and the sludge thus generated is further processed by drying the same on a non- permeable bed, which upon drying can be used as manure in the green area provided within the project site. The wet sludge is generally removed during the processes of primary treatment, secondary treatment and tertiary treatment or scrubbed off of the collection tank.

 Remaining 2% of waste water is evaporated from the system during treatment process and thus cannot be converted into sewage.

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 is being followed. The collected wastes is being stored at designated area and disposed as per the standard procedures in line with the statutory requirement.

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 the waste water from the site up to tertiary level, and be used for flushing, landscaping, etc. Regular monitoring of treated effluent will be carried out to ensure that all parameters are within acceptable limit.

9.2.4 Air Quality Development and Construction Phase The construction phase of the project will last for about 3-4 years, causing 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

M/S DSS BUILDTECH PVT. LTD. 147

EXPANSION OF GROUP HOUSING PROJECT “THE MELIA” AT VILLAGE MOHAMMADPUR GUJJAR, SECTOR-35, EIA/EMP REPORT SOHNA, DISTRICT GURUGRAM, HARYANA

PM 2.5 & PM10 (dust). Likewise, following mitigation measures is being 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 is 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 is adequately covered and contained.  Training to the workers to reduce idling time of machines that otherwise tends to produce hydrocarbons and carbon monoxide.  Best practices for maintenance and repair of all machineries and equipment. Operation Phase During the operation phase, following measures will be adopted for air pollution control:  Adequate stack height for DG sets  Low sulphur diesel based DG sets  Traffic management to avoid congestion  Green belt plantation

DG Set: The running of DG sets will result in emission of various pollutants. To achieve adequate natural dispersion, adequate stack height will be provided as per guidelines of Central Pollution Control Board (CPCB).

Traffic management: Internal roads would be maintained in good conditions to control the dust emissions and adequate width will be provided to avoid traffic congestion.

10.20 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 and management plan are discussed below.

10.2.1 Land Environment The site falls under residential land use as per the development plan by Gurgaon Master Plan, 2031. The construction phase of a project may pose threat of soil contamination and soil erosion. Inadequate solid waste management may also cause soil contamination during operation phase.

During construction phase, excavation related work avoided during the monsoons and site clearing is being carried out for specific areas being developed. Recyclable and non-recyclable wastes are disposed through a local approved agency. Municipal Solid Waste Management is proposed as per Municipal Solid Wastes (Management and Handling) Rules, 2016.

10.2.2 Water environment The water requirement during construction phase will be met from STP treated water of 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.

The wastewater will be treated in 1 onsite STPs of Total 875 KL capacity generating 376 KLD of treated effluent for reuse in flushing, horticulture and HVAC cooling.

10.2.3 Air Environment During construction phase, the major air pollutant is particulate matter as impacts of other emissions such as SO2, NO2, and CO is not be significant.

Monitored average PM2.5, PM10 level not exceeded NAAQS at all the ten locations. The levels of

PM2.5, 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 will require comprehensive mitigation measures and best construction practices. Adequate stack heights have been proposed for D.G. sets i.e. 6 m above the rooftop to provide sufficient dispersion of pollutants. Water sprinklers will be used to suppress dust during construction. During the operation phase, green belt is proposed to restrict and absorb air pollutants.

10.2.4 Noise Environment Noise levels were observed at four locations within the study area. Levels of background noise monitored in exceed the limit at 55 dB (A) and 45 dB (A) for daytime and night time respectively. The noise emitted from heavy-duty construction equipment’s during construction period being high will require occupational preventive measures and temporary noise barriers for noise attenuation. The construction period being about three to four year duration, will require significant mitigation measures such as restricted loud noise activities to daytime and provision of PPEs In the operation phase, noise pollution will be checked through acoustic enclosures of DG Sets and green belt plantation.

10.2.5 Biological environment The landscape area will be developed with native species that will attract local birds and insects, reduce pollution and improve aesthetics and micro-climate of the region. Total green area measures 20,494.66 m2 (30.17 % of plot area) which include area under tree plantation and lawn.
