1 1. Increased water demand (12 KLD) due water usage for, dust suppression and for workers 2. Sewage generation (11 KLD) and disposal 3. Municipal solid waste generation (15 kg/day) by workers 4. Construction activity may lead to Water on site Unsanitary conditions logging and mosquito breeding on site Sedimentation of outside drains Water on site Unsanitary conditions logging and ENVIRONMENTAL MANAGEMENT PLAN Use of polymeric spray for dust suppression instead of water wherever possible Curing water shall be sprayed on concrete structures, free flow of water shall not be allowed for curing Use of wet jute cloth/ gunny bags instead of water spray for curing activity. Disposal of sewage into sewer line Daily watch on sanitation facilities, drains & good housekeeping Segregation of Biodegradable (6 Kg/day) and non-biodegradable garbage (9 Kg/day) Disposal of segregated waste to MIDC Computation of the runoff within the plot. Proper management of channelization of storm water Use of screens and silt traps in advance of earthworks Proper maintenance of storm water drainage to avoid choking of drains and flooding on site Prompt completion of works relating to drainage and sediment control CONSTRUCTION PHASE 1.Construction 2.

2 mosquito breeding on site Ensure discharge of storm water the site or inflow to the site due to contributing catchment is clear of sediment and pollution 5. Construction activity a. Dust generation Use of polymeric spray wherever possible / water for dust suppression b. Noise & Vibration Regular noise monitoring to be scheduled to maintain the noise level within the levels prescribed by CPCB during day and night time Provision of ear plugs to workers Sedimentary controls to be implemented c. Disruption of soil & runoff d. Oil leaks Regular maintenance of machineries to prevent and repair leaks Contaminated soil (if any) disposed to authorized CHWTSDF e Generation of waste/ Excavation material Top soil shall be preserved and used for gardening Excavation material shall be reused on site for backfilling and leveling and remaining shall be disposed to authorized landfill site. Construction waste like (concrete waste, steel, bricks and blocks, ceramic tiles, marble or granite) shall be partly recycled and remaining shall disposed to authorized recycles Disposal of hazardous 1. Site Engineer, Site Architect 2. Supervisor : Reporting for the status of Pollution prevention and control measures to Manager 3. Manager Coordination with MoEF/ NABL approved External Laboratory for monitoring and Overall documentation and record keeping for the statutory approvals -- For (approx. 3 years )

3 6. Vehicular movement Increase in traffic Air emissions & Noise Oil leaks 7. Use of DG sets may leads to air and noise pollution 8. Impact on health of workers Accidents, Hazards, injuries to workers waste to CHWTSDF Construction waste (Empty Cement Bags, Paint container, other Barrels & Scrap metal) will be handed over/sold to Authorized recyclers Proper traffic management for the vehicles Provision of oil and grease traps to the Storm water drains Contaminated soil found if any to authorized CHWTSDF Regular maintenance of vehicles with suitable enclosures and intake silencers Planning and ensuring effective of the waste movement plan for loading and offsite movement in non-traffic hours DG sets with inbuilt acoustic enclosures Site barricading Regular maintenance Adequate drinking water, canteen, toilet and bathing facilities First aid facility & Regular health checkup of workers & Proper security arrangements Risk assessment and preparation of disaster management plan Provision of temporary 1.Site Architect 2.

4 water tank for firefighting and appropriate fire suppression measures Safety educational and awareness programme No. 1. Increase in water demand (179 KLD) 2. Sewage generation (213 KLD) OPERATION PHASE Use of treated sewage for flushing (108 KLD), gardening (60 KLD) and part cooling tower make up. Use of Treated Waste Water for flushing, gardening and part cooling tower make up resulting in reduction of Net water demand by 52% Use of harvested rain water for domestic purpose (84 KLD) and its reuse thereby reducing the fresh water demand. Provision of STP of capacity 230 KL for treatment of sewage up to tertiary level. Proper operation and maintenance of STP and Daily analysis of general parameters like ph, BOD, COD and TSS & O & G of the STP outlet to ensure good treatment of waste water with the help of sensors & to ensure discharge standards as per EP Act Excess treated sewage during monsoon season shall be discharged as per the CPCB norms. Ventilation around the STP of the Staff / Water Act 1974 as amended --

5 Proper arrangements for sludge handling and disposal 3. Increment in Minimizing the incremental runoff Runoff (2.18 the site with the help of rain 3 water harvesting tanks of adequate m /sec) site capacity. Proper management of channelization of storm water site by using proper SWD and discharge points of having adequate capacity. Use of screens and silt traps to SWD Proper maintenance of storm water drainage to avoid choking of drains and flooding on site 4. Power demand Provision of energy saving measures: High Efficient Chiller COP of 6.4 Operating at Elevated Temp, Primary variable pumping, Low Approach Cooling Tower ( 5 deg F) DOAS for treating latent load. LEDs for Lighting in Common Areas 5. Use of DG sets Stack height as per CPCB norms may lead to air Good Landscaping trees and noise DG sets with inbuilt acoustic pollution enclosures 6. Vehicular movement Increase in traffic Air emissions & Noise Contamination of soil (if any) leads to Oil leaks As per the current status of the proposed site, moving vehicles on nearby roads were the major contributor of air pollution. Even after completion of project moving vehicles would be the major contributor of air pollution. The pollution load would not exceed CPCB standard even after completion of the proposed project Shared taxi and auto services would be arranged Bus routes along with its schedule and railway time table would be displayed near the project site in near future Developer is developing a landscape area which would be offsetting of CO2 emissions vehicles Society/ SWD NOC MIDC ECBC norms CPCB specification 7.

Disasters like Fire, lightning, Earthquake etc. area Proper housekeeping and maintenance Informing and educating occupants for solid waste management Provision of adequate space for solid waste management Proper segregation on site to biodegradable and nonbiodegradable. Recyclable waste: To recyclers Biodegradable waste (222 kg/day) Treatment in Organic Waste Convertor (OWC) End product OWC and sludge generated STP shall be used as manure on site Quarterly monitoring of manure Preparation of Disaster Plan Provision of Safety officer, Security and First aid team Regular review of DMP and mock drill Effective of DMP Society/ Society/ Safety Officer as amended -- CFO NOC
