1 Executable EMP for Residential & Commercial Project by Ms. Abisky Ritkriti Keshavnagar LLP Project Location: S.No. 8/3/2, 8/3/3, Mundhwa, Tal- Haveli, Dist- Pune. Project Details: 1 Plot Area sqm 2 BUA sqm 3 Buildings 2 residential, 1 commercial 4 Tenements Population P age

2 1. Air Environment: 1.1 Construction Phase a) Mobile source emissions I. Transportation of raw materials required for construction will be carried out during non-peak hours. Proper traffic management for construction vehicles. II. Parking of delivery trucks or other equipment will not be permitted on public road during unloading or when not in active use. III. To minimize dust emissions due to trucks carrying cement, gravel, sand to site, ready mix concrete carried in enclosed container will be used, which is a better option as compared to on site batch mixing. IV. Use of Dust Control measures during material transport like Water Sprinkling, Covering the trucks. b) For stationary source emissions: I. Most of the machinery related to construction will be located close to construction area for ease of handling. Machinery such as crushers, conveyers and mixers will be screened with sheets of suitable material to reduce generation of suspended particulate matter and noise. II. Areas prone to fugitive dust emissions due to activities such as excavation, grading sites and routes of delivery vehicles across patches of exposed Earth, will be frequently water sprinkled to prevent re-entrainment of dust. III. Apart from these, equipment/machines and vehicles will always be kept in good state of repair to minimize emissions. Low emission vehicles/equipment should be used wherever feasible. Construction areas will be enclosed, wherever possible. 1.2 Operation Phase: Use of 2 DG set (DG set: 180 KVA x 1 Nos. & 40 KVA x 1 for commercial) as per CPCB norms; HSD used as fuel Optimum Air to Fuel ratio for Reduced NOx Levels Adequate Parking provision with driveways Effective traffic management Half yearly monitoring for AAQ will be done as per CPCB guidelines 2 P age

3 2. Water Environment: 2.1 Construction Phase Construction water requirement met through tankers Monitoring of surface and ground water for change in quality due to construction activity. Drinking water analysis (Monthly) Provision of temporary toilets with proper disposal of sewage through public sewer line Use of tanker water for construction 2.2 Operation Phase We will install scientifically designed Rain Water Harvesting System, Sewage Treatment Plant. Rainwater harvesting system will have two-fold objective: 1. To utilize rain water available on the plot in direct way or indirect way to reduce the load on water supply system. 2. To minimize the storm water drainage load to avoid water logging locally as well as on larger scale. The total water collected by rainwater harvesting on the plot will be used for Ground water recharge which would increase ground water table of the area and reduce storm water quantity. We will implement properly designed storm water drains. Rain water harvesting will be done through 10 Nos. Pits Operation and Maintenance for Rain Water Harvesting System: Sr. No. Activity O and M Frequency 1 Harvesting The roof top shall be Yearly clean water made free of dumps and unwanted material.

7 5. Land Environment 5.1 Resource Management: The resources such as sand, metal etc will be taken from Govt. owned / approved agencies. One of the impacts on the land environment during construction phase is the requirement of construction materials as identified. It is proposed to use fly ash to partially offset use of cement in the construction. This will reduce sand requirement by about 20% & will also solve the problem of fly ash disposal. The proposed project involves removal of sub-stratum during excavation for foundation. The impact of excavation for foundation will be reduced due to use of excavated material / debris generated for filling purposes and for road construction. The solid waste generated due to packaging material will preferably be recycled and/or reused. 5.2 Traffic Management: Another impact identified during studies is the minor increase in traffic volume in the area in construction phase (because of the movement of trucks carrying raw materials) & in operation phase (due to vehicles movement for ferrying building occupants) Special care will be taken during transportation of construction material like cement, sand, aggregate etc as such material would be transported from various material suppliers. Since road transport is unavoidable, such movement will be carried out during non- peak hours as far as possible. The entry/exit to the site will be with adequate curvature at turning so that vehicles coming out/entering the building do not impinge on road traffic directly. As far as possible, material carrying trucks should be parked inside the complex & should not be parked on public road. 7 P age

8 6. GUIDELINES FOR BIO-AESTHETIC MANAGEMENT 6.1 Green belt/landscape Management Greenbelt is important feature as far as landscape of the premises as well as biological environment is considered. Purpose 1. Enhancement of aesthetic value of the area 2. Proposed project is Residential Complex so proper landscape management is necessary to beautify the area. 3. Help to reduce Air and Noise pollution. 4. Prior to plantation of trees Ecological value as well as aesthetic value of tree species should be considered. 6.2 Plantation Specifications: Trees should be planted in 1 cu. m pits. The tree pits should preferably be in a row that is not concretized, with exposed ground, to facilitate infiltration of more water into the ground and healthy growth of root system. Good anchorage would help minimize uprooting of trees during unfavorable weather conditions. The pit should be filled with an even mixture of red earth, sand and farmyard manure. Saplings should be healthy 3-year old in age to ensure better survival. Trees should be watered on alternate days during dry season, for 4-5 years. Weekly watering is often required at later stage of growth. During this growing period, care should be taken to ensure that the tree is growing vertically and is without horizontal branches. Any branch appearing within 8 feet from ground should be removed by sawing at the trunk level. 6.3 Some Recommended species for plantation: Butea monosperma Ficus blackiana Azadiracta indica Cassia fistula Cordial sebestena Lagerstromea sperciosa Spathodia campulata Milingtonia Hortentis Plumeria alba Murraya panniculata Mangifera india Butea monosperma Ficus blackiana Azadiracta indica Cassia fistula 8 P age

10 8. Socio Economic Aspects The proposed construction project is specifically demarcated for residential development. Thus, there would not be any adverse impact on local population due to the project. This is seen as a positive impact on socio-economic environment as it will create additional jobs & give thrust to development of services sector in the city. 8.1 Construction phase: The health and safety of the workers for the construction project should be ensured by: Adequate drinking water, toilet and bathing facilities for workers Personal protective and safety equipments will be provided. Doctor & First aid facility for workers Crèche for children of workers Regular health check up for workers Educational and awareness program for safety measures 8.2 Operation Phase: For safety purpose during operational phase Awareness programs regarding socio-economic impacts of residential projects on surrounding area. Environmental and safety awareness programs for surrounding area. Disaster management/emergency preparedness plan will be explained with the help of experts. In addition, we will construct a compound wall of 1.5 M height and plant the trees within premises along compound wall, to attenuate the noise level. Periodic inspection and of all water storage tanks should be carried out at regular intervals to prevent outbreak of waterborne diseases 9.Responsibilities: 1. During construction phase, contractors as well as site-in-charge will be responsible for implementing all the mitigation measures recommended. 2. Planting of trees on open spaces and road-side should be initiated during construction phase itself. 3. In operational phase, the work will be continued along with post-monitoring of planted area. An officer will be appointed by us to ensure monitoring and inspection during construction period as explained above. 4. Prime properties have constituted Environmental Management Cell (EMC) including in-house and outside experts (5 in Number) to deal with environmental issues at 10 P age

11 project stage for every project site. EMC meets every fortnight and assess the environmental issues at various on-going sites. After the society formation, a special training program to be organized for society office bearers to look into environment management in project operation stage. 9. Regulatory Compliance: 1. Obtain Consent to Establish from MPCB before start of work 2. Obtain Consent to Operate from MPCB before occupation of project. 3. Six monthly compliance for air, water, noise, soil monitoring and submission to MoEF. ******* 11 P age
