9 4.0 ENVIRONMENTAL MANAGEMENT PLAN DURING CONSTRUCTION PHASE Environmental pollution is inevitable during the construction phase. The project proponent should take appropriate steps to control pollution during construction phase. The following are the factors requiring control during construction phase. 4.1 SITE PREPARATION The following control measures will be followed during the site preparation Topsoil will be stripped to a depth of 200 mm from areas proposed to be occupied by buildings, roads, paved areas and external services. Top soil will be stockpiled to a height of 400 mm in pre - designated areas for preservation and will be reapplied to site during plantation of the proposed vegetation. Measures will be applied to control erosion of preserved top soil. Top soil will be separated from sub-soil debris and stones larger than 50 mm diameter. To keep the damage to topsoil minimum, excavators will be used for construction. Temporary seeding will be carried out to reduce erosion and sedimentation from disturbed areas Temporary seeding will be performed on areas which have been disturbed during construction and which are likely to be disturbed after a few weeks. For this time gap the top soil will be preserved from erosion through temporary measures like temporary seeding. 4.1 AIR ENVIRONMENT Dust is the major emission during the construction period. The following control measures will be followed during the construction period Application of dust suppressants will be done Locally available gravel will be applied to the roads and lots, to prevent the dust emanation Measures will be taken to cover the stored materials to prevent the dust emission during high winds 8

10 Speed of the vehicles in the project area will be limited 20 Kmph Rescheduling the works during high speedy winds Inspection will be done for use of covering sheet to prevent dust dispersion at buildings site 4.2 WATER ENVIRONMENT Water required during the construction the will be met from the ground water resources. Total water requirement during construction period will be 10 KLD and construction period lasts for period of 36 months. The following control measures will be taken to reduce the reduce the water requirement during construction Curing water will be sprayed on concrete structures; free flow of water will not be done for curing. After liberal curing on the first day, all concrete structures will be painted with curing chemical to save water. This will stop daily water curing hence save water. Concrete structures will be covered with thick cloth/gunny bags and then water will be sprayed on them. This will avoid water rebound and will 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. Waste water management during construction Waste water generation will be minimized by following above control measures Sanitary waste water generated during construction stage will be septic tank followed by soak pit 4.3 NOISE ENVIRONMENT The main sources of noise in the process of construction activities will be cement concrete mixing, welding, aluminum channel folding, drilling and DG sets etc. Diesel generator sets will be provided with integral acoustic enclosure at the manufacturing stage itself 9

11 Equipment like earmuffs, earplugs etc. will be used for hearing protection for workers. 4.4 LAND ENVIRONMENT Solid waste generation & Management Proper planning and management during construction period is very much vital. We proposed to implement the following control measures to mitigate the waste generation Delivery of material on site will be done over a durable, impervious and level surface, so that first batch of material does not mix with the site surface. Availability of covered storage will be assured. The recyclable items like metal, plastic will be sent to recyclable industry, and rest of this scrap will be stored in a covered area. Wherever materials (aggregates, sand, etc.) are more likely to generate fine airborne particles during operations, nominal wetting by water will be practiced. Workers / labour will be given proper air masks and helmets. Skilled labour and good workmanship will be employed for judicial utilization of materials and minimizing the waste. Proper estimate of material will be done to minimize the undue wastage. Contaminated runoff from storage will be captured in ditches or ponds with an oil trap at the outlet. Materials wasted on site will be reused at the same place Waste management & recycling The construction 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 etc. 10

12 Waste recycling Plan Waste and recycling plans will be developed prior to beginning construction activity. The plan aims at identifying wastes to be generated, and designate handling, recycling and disposal method to be followed. Handling Handling of waste material requires special precautions such as personal protective equipment and special procedures to prevent the injury. Safe operating methods will be developed for waste collection, storage, and disposal operations in a manner to protect the health and safety of personnel, minimize environmental impact and promote material recovery and recycling. Waste Segregation Gross segregation of construction wastes into roadwork materials, structural building material, salvaged building parts and site clearance wastes will be done and additional segregation will be done to facilitate reuse/ recycling. Storage Adequate provision will be made for storage of solid waste and for easy access to the dustbins for labours from source to the place of storage, and from the place of storage to a collection point specified by the waste collection authority and/or contractor Two colours of wheeled bins: o Green colour for wet waste, o Blue for dry waste A minimum of 4% of the total site area will be allocated for storage and pretreatment of the waste. This storage area will be covered to prevent any impact on surrounding. 11

13 5.0 ENVIRONMENTAL MANAGEMENT PLAN DURING OPERATION PHASE 5.1 Air Emission Management During operation of the proposed, the emissions will be mainly from DG Sets which will be used for backup power supply and vehicles. Emissions will be mainly Particulate matter, NHMC, CO and Nitrogen dioxide. The following control measures will be taken up during the operation All the internal roads will be grass paved. This will reduce the dust generation due to the vehicular movement Stack of adequate height will be provided to the DG Sets as per CPCB guidelines Green belt will be developed in the premises of complex which will act as sink for air emissions Hence there will not be any impact on surrounding environment due to the air emissions from the proposed. BASELINE DATA Baseline data has been monitored at the site for particulate Matter (PM 2.5 ), particulate Matter (PM 10 ), Sulphur dioxide (SO 2 ) & Nitrogen oxides (NOx) concentrations. The following table shows the baseline concentrations. PARAMETER 98 th Percentile CONCENTRATION (g/m 3 ) PM( 2.5 ) 25.5 PM( 10 ) 42.8 SO NOx 21.0 CO

The maximum Ground Level Concentrations occur at a distance of 300 m from the stack in the down wind direction. The emissions due to vehicular traffic are also considered in the Modeling. The following table shows the Net resultant concentrations of PM 10, NOx & CO. NET RESULTANT MAXIMUM CONCENTRATIONS DUE TO THE PROJECT Item PM 10 µg/m 3 NOx µg/m 3 CO µg/m 3 Maximum baseline Concentration in the Project area Maximum predicted incremental rise in concentration due to the project Net Resultant concentration after occupancy of complex National Ambient Air Quality Standards vide order No. S.O. 826 dated The net resultant concentration of PM 10, NOx & CO are within the National Ambient Air Quality Standards. Hence there will not be any adverse impact on air environment due to the proposed project. Recommendations a. All the internal roads shall be grass paved to reduce the fugitive dust due to vehicle movement. b. Greenbelt shall be provided around the boundary and along the internal roads. 13

15 5.2 WATER POLLUTION MANAGEMENT Water usage for applications such as flushing and washing will be as high as 93% of water demand in any building. In view of the above, we proposed to adopt the following measures to reduce this demand Water meter 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. This would also enable the user to identify if there are any points of leakages. Dual flush systems will be installed in order to allow different volume of water for flushing liquids and solids. Sensors based fixtures will be fitted which function only in presence of users. These sensor-operated taps help in reducing water consumption and also result in maintaining better hygiene Tap aerators will be installed which facilitate cleaning through increasing the pressure at which the water is delivered even at low flow rates. Pressure reduction device will be installed which will affect the discharge rate and also to maintain uniform flow at different levels. Waste water generation Only source of waste water generation will be sanitary waste water which will be treated in STP with Moving bed bio-reactor. The treated waste water will be utilized for non-potable purposes like Toilet flushing & gardening. Remaining waste water will be discharged in to the nearest drain. During construction of residential complex Dual Plumbing system will be done. Two separate water tanks will be provided for storingtreated wastewater & another for fresh water. Separate pipeline system will be provided to treated wastewater tank to pump the water for toilet flushing & gardening purposes. There by net water withdrawal will be reduced. The total Water Requirement - 83 KLD Total Wastewater generated - 71 KLD The Treated wastewater reused - 26 KLD 14

16 The net water requirement after reuse - 57 KLD The following are the characteristics of Untreated Wastewater Constituent Unit Range ph Dissolved mg/l Volatile mg/l Suspended mg/l Settelable mg/l BOD 5 mg/l COD mg/l 200-1,000 Total Nitrogen mg/l Alkalinity mg/l Grease mg/l Total Coliform colonies/100 ml SOLID WASTE Waste, generated by will be generally from restaurants, plastic & metal and dusting. In the proposed residential complex, waste segregation will be done at the source by placing two types of the bins at all the strategic locations. Green: wet waste Blue : dry waste The plastic waste will be disposed off to the waste recyclers and bio-degradable waste will be disposed to the GHMC bins. Kitchen and food waste will be bio-composted within the complex premises. 15

17 The following will be the solid waste generation during operation of the S. No SOLID WASTE QUANTITY DISPOSAL 1. Municipal Solid Waste 0.3 T The garbage will be segregated at source through collection bins into Biodegradable waste and Non Biodegradable waste. Plastic waste will be given to the waste recyclers and kitchen and food waste will be converted to manure through organic waste convertors. 2. Sludge from STP 7.1 Kg/day Stored in HDPE bags and will be used as manure / given to farmers. 3. Waste oil 200 Lit /Annum Will be given to SPCB approved vendors. 4. E-waste 2 T/annum Will be given to SPCB approved vendors. 5.4 NOISE LEVEL MANAGEMENT DG sets will be provided with acoustic enclosure, which would restrict the noise level to 75 db(a) at a distance of l m from the acoustic enclosure. The DG sets would be mounted on the anti vibration pads to restrict the vibration. There will be slight increase in traffic noise due to the proposed project. However the Noise levels will be within the standards prescribed by CPCB / SPCB. Hence there will not be any impact on Noise environment due to the proposed project. 5.5 LAND ENVIRONMENT All the pavements in the site area will be grass paved, which will mitigate the dust generation from the vehicles. Vehicle speed in the complex area will be reduced which will reduce the emissions. Greenbelt will be developed in the complex area which will acts as sink for the emissions. Hence there will not be any deposition of pollutants in the surrounding area. 16

18 The sanitary waste water generated from the will be treated in Moving Bed Bio Film reactor and treated waste water will be reused for non-potable purposes like flushing and greenbelt development. No wastewater will be disposed to the outside. Hence zero discharge system will be implemented. The solid waste generated from the complex will be disposed as per norms. Hence there will not be any impact on land environment due to the proposed Residential complex Recommendations a) Land scaping will be done along the periphery of the compound wall. 5.6 GREEN BELT DEVELOPMENT Greenbelt will be developed all around the periphery of the compound wall along with some part of the Greenbelt will be developed in Open spaces. The greenbelt shall be developed simultaneously with the plant construction. This will further mitigate the pollution impacts. Greenbelt plantation Greenbelt is developed in a set of rows of trees planted in such a way that they form an effective barrier between the plant and the surroundings. The main purpose of greenbelt development is to contribute to the following factors. To maintain the ecological homeostatus. To attenuate the dust emissions and lower SO 2 levels To prevent the soil erosion. To attenuate the noise levels. To utilize the treated effluents. Selection of species The following main criteria will be followed for selection of plants: Trees, shrubs having dense foliage with a large surface area, as leaves absorb pollutants. Evergreen trees as they are found to be more effective. The species resistant to pollutants, particularly in the early stages of their growth. 17

19 The following species are planned to be selected for greenbelt development in the complex premises Citrus species Dyospyros species Ficus bengalensis (Banyan) Lillium spp. (Lily) Polyathia lotigifolia (Ashok) Tamarindus indica (Imli) Thuja occidentallis (Cedar) Prospis Juliflora (Mesquite) Zizypus jujuba (jujuba), etc. Greenbelt development plan Green belt will be developed all around the complex area Out of the total site area 10.08% of area will be allocated for greenbelt development The tree species to be selected for the plantation are pollutant tolerant, fast growing, wind firm, deep rooted RAINWATER HARVESTING In the proposed complex prior planning has been to construct a rain water harvesting pits will be constructed to augment the precious rain water. Due to this impact on groundwater table will be minimized. Measures to ensure water quality To ensure the good quality of rain water the following control measures are proposed o Catchments such as roofs will be made accessible for regular cleaning and ensuring no dead animals etc are present on the surface. o The roof will be made of non- toxic material, having smooth, hard and dense surface o All gutter ends will be fitted with a wire mesh screen and a first flush device will be installed. Most of the debris carried by the water from the rooftop like leaves, plastic bags and paper pieces will be arrested by the mesh at the terrace outlet and contamination will be prevented to a large extent by ensuring that the runoff from the 18

20 o o first minutes of rainfall is flushed off. Remaining contaminants like silt and blow dirt will be removed by installing appropriate filters. No sewage or wastewater will be admitted into the system. For runoff from parking lots and roads, grease filters etc. will be arranged to prevent risk of contamination from chemical spillage. Total Harvested Rainwater Site is proposed to have rain water storage of 10 Cum. Excess rain water will be diverted to recharging pits. A total 10 no's of recharging pits, each with 3 cum/day capacity will be provided. Total Harvested Rainwater Rain water harvesting structures will be constructed to harvest the run-off water from roof tops by laying a separate storm water drainage system for recharging of ground water. Ground rainwater harvesting system: Artificial recharge or ground water rainwater harvesting is a process by which the rain water from paved areas will be collected through a storm water network. And will be connected to Rainwater harvesting pit. Rooftop rainwater harvesting system: In rooftop harvesting, the roof becomes the catchments, and the rainwater will be collected from the roof of the each building. Rainwater from roof or terrace will transported using PVC gutters. Rainwater harvesting pits collect all the rainwater. So that groundwater table will be recharged and utilized for future use. 19
