15 ENVIRONMENTAL MANAGEMENT PLAN Introduction M/s Gurukrupa Developers proposes a Slum Rehabilitation project Amrut Manthan + Shree Mahalaxmi & Primus Residences located at C.T.S. No. 4091, 4091/1 to 37, 4097, 4097/1 to 5, 4090B & 4090A/2 to 19 of village Kolekalyan, Vakola, Santacruz (E), Mumbai, Maharashtra. The project was earlier granted Environment Clearance by SEIAA, Maharashtra vide letter no. SEAC /CR-490/TC- dated 29th April, 2014 for Plot area 5, sq.mt. and Built-up area = 31, sq.mt. It is proposed to modify a part of the project by changing the user of Sale building from Commercial to Residential and configuration from 3 basements + Ground / Stilt + 11 Upper floors to 3 basements + stilt + 15 upper floors with 3 wings, by redesigning. Though, as a result of proposed modification, the plot area remains unaltered, the other features of project like no. of Dwelling Units, Population, Water consumption and Waste generation, etc. will change. Therefore, in view of the above, we seek an amendment in existing Environment Clearance of the proposed project. Type of Project The proposed project Amrut Manthan + Shree Mahalaxmi & Primus Residences is amendment in Environmental Clearance as there is change in area details. Total plot area remains same. The built-up area after amendment will be 32, sq.mt. Hence, it falls under category 8 (a) of EIA notification, Earlier the Environmental Clearance was granted on built up area 31, sq m. Project Details The proposed project Amrut Manthan + Shree Mahalaxmi & Primus Residences is amendment in environmental clearance due to change in FAR & Non-FAR area. The Project will be developed by M/s Gurukrupa Developers. The total plot area of the project is 5, sq.mt. and Ground coverage will decrease from 1, sq. mt. to 1, sq.mt. The FAR achieved will increase from 14, sq.mt. to 17, sq.mt. & Non- FAR decrease from 16, sq.mt. to 14, sq.mt. The built-up area of the project will be 32, sq.mt. Total No. of towers will be 2.

Water Management WATER MANAGEMENT DURING CONSTRUCTION Water during construction phase 11 KLD is being taken from tanker water for Domestic & 20 KLD for Construction Activity. The water demand for construction activity and domestic usage may vary as per the actual demand on site. During the construction period, runoff from the construction site is not allowed to stand (water logging) or enter into the roadside or nearby drain. Adequate measures has been taken to collect such run off and either are reused or disposed off at the designated construction waste disposal location WATER MANAGEMENT DURING OPERATION PHASE The ultimate source of water will be through MCGM. Total water requirement of the project will be 127 KLD & 112 KLD for Rehab & Sale Building out of which 84 & 74 KLD will be fresh water respectively. Rest of the 43 & 38 KLD water requirement for Flushing will be fulfilled by treated water. The total daily water requirement and waste water generation calculation is given below:

20 Rain Water Harvesting The main source of ground water recharging in the study area is rainwater, which infiltrates into the ground through various lithological units present in the study area. 6 nos. (2nos. for Rehab and 4 Nos. for sale building) of RWH harvesting structures are proposed in the site to recharge the ground water. The runoff from the rooftop and storm water shall go to the recharge structures. 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 buildings/shall be connected to adjacent drain by our network through catch basins. 1. Since the existing topography is congenial to surface disposal, our storm water network is planned adjacent to roads. All building roof water will be brought down through rain water pipes. 2. Proposed storm water network consists of drains, catch basins and seepage pits at regular intervals for rain water harvesting and ground water recharging. The recharge pits of adequate size with desilting chamber will be constructed for recharging the ground water. 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 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. Provision of 2 Rain water Harvesting pits has been proposed for Rehab Building and 4 Rain water Harvesting pits for Sale building for artificial ground water recharge.

22 Waste Management During Construction Phase Solid waste would be generated both during the construction as well as operation phase. The solid waste expected to be generated during the construction phase will comprise of excavated materials, used bags, bricks, concrete, MS rods, tiles, wood etc. The following steps are proposed to be followed for the management solid waste: Construction yards are proposed for storage of construction materials. The excavated material and useful reusable material will be stacked for reuse. Since this is a redevelopment project, no top soil is available for reuse. The excavated/demolished material shall be utilized for refilling / road work / rising of site level at locations/ selling to outside agency for construction of roads etc. Soil Management During the construction, soil excavated is approx cubic meters. This soil has been stacked properly under Tarpaulin cover. The top soil has been collected and shall be use for landscaping purposes. The excess soil will be sent to landfill site only During Operation Phase Municipal Solid Waste Management: The solid waste will be generated at each house. It will be segregated at individual house levels. They will keep in different colour coded bins. The waste will be collected in bin on each floor marked with different colours. The bins will be emptied into the main bin of the floor. From the bins of each floor, service provider will collect garbage and organic waste from green bins shall be disposed off in OWC. The management shall engage a vendor, who will carry this recyclable waste to the recycler for recycling. Solid Waste Generation during Operation Phase (Rehab) S.

Benefits of organic waste converter: 1. Large quantity of solid waste is converted to manure in a very short period. 2. Manure can be sold as compost to farmers, or used for gardening. 3. Machine requires less space and the efficiency is high. 4. Manpower and maintenance is very less. 5. This is one of the latest techniques of managing solid waste.

24 Hazardous Wastes: Hazardous waste is a waste with properties that make it dangerous or potentially harmful to human health or the environment. The universe of hazardous wastes is large and diverse. Hazardous wastes can be liquids, solids, contained gases, or sledges. They can be the by-products of manufacturing processes or simply discarded commercial products, like cleaning fluids or pesticides. All hazardous wastes are required to be treated and disposed off in the prescribed manner. The main objective is to promote safe management and use of hazardous substances including hazardous chemicals and hazardous wastes, in order to avoid damage to health and environment. Type of Waste Used Oil Colors of Bins Black With Label Category Disposal Method Total Waste Hazardous Waste Waste shall be collected in leak proof containers at isolated place and then it will be given to approved recycler of Central Pollution Control Board as per Hazardous and other Wastes (Management and Transboundary Movement) Rules, Litre/month E-Waste Management: Type of Waste Electronic Colors of Bins Black With Label Category Disposal Method Total Waste Hazardous Waste Parking management: Parking Requirement: It will be collected and given to approved recycler of State Pollution Control Board as per E-Wastes Management Rules, Car Parking Requirement Carpet area of tenements 1 Parking / no. of tenements No. of Tenements Parking required 45 to 70 sq.mt Above 70 sq.mt Total Add. 25% for Visitors Total Car parking required Additional parking - 25% Total Car parking required Say 161 ECS 2 kg/day

This will help in increasing the aesthetic effect of the environment. Since tree trunks are devoid of foliage, scrub should form there to give coverage to the trunks. The trees maintain the regional ecological balance and conform to soil and hydrological conditions. Indigenous species would be preferred. Green belt/greenery has been developed along most of the periphery of the project area as well as along roads. Area under plantation/greenery is sq m with trees and plants. The trees planted are of adequate height. Any trees that do not survive. No. of trees required: Plot Area/80 Sqm= /80 = 69 Nos. No. of trees proposed to be planted: 77 Nos. Sr. No. Common Name Botanical Name 1 Champaka Michelia Champaca 2 Ashoka Polyalthia longifera 3 Neem Azadirachta Indica 4 Kadam Anthocephalus Cadamba 5 Chafa Plumeria Alba AIR MANAGEMENT During Construction Phase: Air quality around the project is adversely impacted due to various construction activities especially related to lose material which are likely to cause generation of dust. To minimize such impact, following measures are being taken: All the lose material either stacked or transported is provided with suitable covering such as tarpaulin, etc. Water sprinkling is being done at the locations where dust generation is anticipated. To minimize the occupational health hazard, proper masks have been provided to the workers who are engaged in dust generation activity.

26 Use of RMC will eliminate the handling of cement, sand and concrete thus dust emission will be minimized. Tarpaulins is being used to cover trucks carrying debris. Another cause of Air pollution during construction phase is the emissions from DG sets The proposed project involves various construction activities; therefore the dissipation of fugitive dusts obvious. These fugitive dusts are being controlled by carrying out construction by covering the boundary of the proposed project site with a green cloth cover up to a certain height and also by intermittent spraying of water During Operation Phase: DG sets of 1 X 320 KVA for rehab and 1 x 630 KVA for sale portion, will be installed for emergency use during power failure. Proper stack height of D.G Set will be maintained which will help in reducing the air pollution. The DG sets will be installed with acoustic enclosure. Table 3: DG sets & stack Height D. G. Set. Capacity No Stack Height 320 KVA meters above roof level 630 KVA meters above roof level As per the specifications from D.G.

The scheme is proven, under a variety of operating conditions, and is highly flexible in operation. Following description gives such salient features: ATTACHED GROWTH PROCESS TECHNOLOGY Aerobic attached growth process is an increasingly popular technology that improves the performance & efficiency of sewage treatment systems. The system consists of microbial activity in suspended phase, as is in the conventional activated sludge systems. In this system the same takes place in the attached phase in addition to the suspended phase. The attached

27 growth phase is maintained through the media submerged in the reactor which provides high specific surface area of media. The media increases the microbial mass in the biological reactor which in turn accelerates removal rate of soluble contaminants and provide additional design capacity relative to conventional systems in the same design volume.

Schematic Diagram of STP Noise Control During Construction: During the construction phase, the noise is being generated for construction equipment, vehicles for transportation of construction materials and operation of DG Sets. The noise level is high during the construction phase but it would be limited only for specific period of construction. Properly maintained equipment with mufflers will be used.

29 High noise generating construction activities would be carried out only during day time. Workers working near high noise construction machinery would be supplied with ear muffs/ear plugs. The techniques employed for noise control can be broadly classified as; Control at Source: Regular servicing and tuning of vehicles reduces the noise levels. Fixing of silencers to automobiles, two wheelers etc., reduces the noise level. The vibrations of materials are being controlled by using proper foundations, rubber padding etc. to reduce the noise levels caused by vibrations. Optimum selection of machinery tools or equipment reduces excess noise levels. Proper lubrication and maintenance of machines, vehicles etc. reduces noise levels Air Pollution Control DG sets of 1 X 320 KVA and 1 X 630 KVA, will be installed for emergency use during power failure. Proper stack height of D.G Set will be maintained which will help in reducing the air pollution. The DG sets will be installed with acoustic enclosure will be provided to control particulate emission. There are two methods to reduce noise from DG Sets. 1. Acoustic Enclosures [when DG Set is kept outdoor] 2. Acoustic Treatment [when DG Set is kept indoor] 2 x 250 kva DG sets which shall be used for common utilities during power failure will be bought acoustically enclosed. Insulation of air inlet and outlet points The sound travels along with air therefore it is necessary to control the travelling sound with the help of insulated ducts [2 glass wool pads and perforated sheets] and louvers at inlet and outlet air points. The ducts have S-type shape to prevent any direct escape of noise Insulated service door The maintenance and servicing of D.G. set is done using a suitable service door of 5 x 7 size. The door is made of MS sheet and frames fully insulated with 3 thick glass wool pad followed by perforated aluminum sheets.

30 Antivibration Pads Layout Plan of D.G Set Room DESIGNING OF CANOPY OF DG SETS Specification of D.G set: The DG sets are smaller and lighter than any other DG set in its class, thus uses less space. The DG sets are manufactured with the lowest noise levels in its range and are CPCB certified for emissions compliance, thus are environment friendly. Engine and alternator are mounted on a common MS fabricated base frame with AVM pads. Hence generated minimum vibration. Fuel tank suitable for 8 hours of operation Engine: diesel generating sets, are radiator cooled, four stroke and multi-cylinder, conforming to BS 5514/ISO 3046
