Car 2-Wheelers FIRST BASEMENT SECOND BASEMENT THIRD BASEMENT Total Parking Area Population Details The total population of proposed project (staff + visitors) has been estimated around persons. 3.0 METEOROLOGICAL DATA Dispersion of different air pollutants released into the atmosphere has significant impacts on neighborhood air environment. The dispersion/ dilution of the released pollutant over a large area will result in considerable reduction of the concentration of a pollutant. The dispersion in turn depends on the weather conditions like the wind speed, direction, temperature, relative humidity, mixing height, cloud cover and also the rainfall in the area. Normally the impacts surrounding the project site are studied in detail. a. Temperature The diversity of the physical features results in a corresponding diversity of climate. The maximum temperature is 40 C observed in May month and minimum is 10.0 C observed in December. b. Rainfall Predominant rainy season (Monsoon) June to September Average mean rainfall in 24 Hr mm 4.0 REQUIREMENTS OF THE PROJECT 4.1 Water Requirement and Supply System Total water demand is anticipated to be KLD. Domestic water requirement for the project is KLD which will be met by supply from Municipality & ground water. It is expected that the project would generate approx. 400 KLD of wastewater (@90% of the total domestic water % of Flushing). The details of water consumption and wastewater generation are shown below: 8

11 5.0 ENVIRONMENTAL MANAGEMENT PLAN 5.1 Environmental Management during Construction The impacts during the construction phase on the environment would be basically of temporary in nature and are expected to reduce gradually on completion of the construction activities Air Quality Mitigation Measures Most of the construction dust will be generated from the movement of construction vehicles on unpaved roads. Unloading and removal of soil shall also act as a potential source for dust nuisance. The control measures proposed to be taken up are given below. Water sprinkling on main haul roads in the project area is done, this activity is carried out at least twice a day. The duration of stockpiling of excavated mud is short as possible as most of the material will be used as backfill material for the open cut trenches for road development. Temporary tin sheets of sufficient height (3m) were erected around the site as barrier for dust control. Tree plantations around the project boundary shall be initiated. All vehicles carrying raw materials were covered with tarpaulin / plastic sheet, unloading and loading activity was stopped during windy period. To reduce the dust movement from civil construction site to the neighbourhood the external part of the building was covered by plastic sheets Water Quality Mitigation Measures During site development necessary precautions were taken, so that the runoff water from the site gets collected to working pit and if any over flow is there, it was diverted to the greenbelt / plantation area. During construction activity all the equipment s washed water was diverted to working pit to arrest the suspended solids if any and the settled water was reused for construction purposes, and for sprinkling on roads to control the dust emission, etc. The waste generated from the site work shop will be segregated like used oil, lubricants, etc. and disposed to authorized recyclers the waste like soiled cotton, paper, etc. will be disposed to municipal bins. 10

12 The domestic wastewater generated from temporary toilets used by the work force was diverted to septic tank followed by soak pit. Therefore, impact on water quality due to project would be insignificant Noise Mitigation Measures Temporary tin sheets of sufficient height (3m) were erected around the noise generating activity or all around the project site as barrier for minimizing the noise travel to surrounding areas. Therefore, impact on noise environment due to project was insignificant. All vehicles entering into the project were informed to maintain speed limits, and not blow horns unless it is required. Personal protective equipment like earmuffs, helmets covering ears were provided to the workers working near noise generating equipment Solid Waste Mitigation Measures Solid Waste generation during Construction Phase The Quantity of waste produced by building construction industry is as follows: Quantity of waste generated (TPM) S.no Constituent Quantity of waste generated (TPM) 1 Soil, Sand and Gravel 4.20 to Bricks and Masonry 3.60 to Concrete 2.40 to Metals 0.60 to Bitumen 0.25 to Wood 0.25 to Others 0.10 to 0.15 Source: The solid waste generated during construction period is predominantly inert in nature. However maximum effort would be made to reuse and recycle them. Most of the solid waste material will be used for filing/ levelling of low-laying areas, as road construction material, if any excess given to local contractors for lifting and dumping in low lying areas. All attempts would be made to stick to the following measures. All construction waste was stored within the site itself. Materials, which can be reused was used for construction, levelling, making roads/ pavement. Recyclable materials will be sold to the authorised recyclers. 11

13 5.1.5 Ecological Aspects During construction period the removed top soil is stored and was used for greenbelt development. A comprehensive green belt program was planned to improve the ecological condition of the region Site Security Adequate security arrangement was made to ensure that the local inhabitants and the stray cattle are not exposed to the potential hazards of construction activities. Round the clock security personnel will be appointed to restrict entry of unwanted people to the site. 5.2 during Occupation Stage Necessary control measures will be undertaken at the design stage to meet the statutory requirements and towards minimizing environmental impacts. During project implementation period special emphasis will be made on measures to minimize effluent generation and dust control at source. The specific control measures related to air emissions, liquid effluent discharges, noise generation, solid waste disposal etc. are described below Air Quality Management The main activities from the proposed project which cause air pollution are as follows: Sulphur dioxide and Nitrogen oxide from DG set Dust particulates due to movement of vehicles and road sweepings The following methods of abatement will be employed for the air pollution control. DG set will be provided with a stack height meeting MOEF Guidelines or 1 m above the tallest structure in the project area for proper dispersion of sulfur dioxide and oxides of nitrogen. Internal roads will be concreted / asphalted to reduce dust emissions Speed restriction will be followed within the project and speed breakers will be provided at entry and exit points Water and Wastewater Quality Management Total water demand is estimated to be KLD. Domestic water requirement for the project is KLD which will be met by Municipal Supply/Ground Water. Water balance of the proposed project is shown in Fig - 6. Total wastewater generated from the project will be 400 KLD. This will be treated in an STP of 515 KLD capacity. 12

14 Sewage Treatment Plan The sewage treatment plant is designed to treat 515 KLD of sewage. FIG 6: WATER BALANCE DIAGRAM Domestic Water Requirement (Municipal Supply & Ground Water) KLD (Fresh Water Treated Water (Flushing) 140) Losses (64 KLD) 400 KLD 19.2 KLD HVAC Cooling (216.0 KLD) KLD Sewage Treatment Plant (515 KLD) Treated Water From STP (360 KLD) Reuse 140 KLD Losses (40 KLD) Water For Greenbelt (7.0 KLD) Water For DG Cooling (16.2 KLD) Design of Sewage Treatment Plant : Effluent Water Specifications S. No. Parameters Value 1 Raw Sewage Quantity 400 KLD 2 Expected average BOD of Raw Sewage mg/l 3 Expected average COD of Raw 600 to 800 mg/l Sewage 4 Expected suspended solids of Raw 200 to 300 mg/l Sewage 5 Expected ph of Raw Sewage 6.5 to Oil and Grease mg/l The basic principal of the moving bed bio reactor process is the growth of the biomass on plastic supports that move in the biological reactor via agitation generated by aeration systems (aerobic reactors) or by mechanical systems (in anoxic or anaerobic reactors). The supports are made from plastic with a density close to 1 g/cm 3 letting them move easily in the reactor even when the capacity reaches 70%. 13

15 The treatment process mainly depends on flow rate of waste generated; BOD/COD of the effluent, presence of any hazardous matter etc. The treated water after tertiary treatment has following uses: Washing Road Cleaning Gardening Flushing HVAC Cooling The Combine Treatment Plant includes three steps: Primary Treatment: For removal of suspended solids from waste water. This will reduce additional BOD load and prevents damage to compressors, Motor and pump. Secondary Treatment: For reduction of BOD/COD of sewage. Tertiary Treatment: For finishing and removal of traces of impurities from treated effluent water. Treatment Scheme for Treatment of Effluent: 1. Bar Screen 2. Equalization Tank 3. Aeration or Bioreactor Tank 4. Tube Settler 5. Pre-filtration Tank 6. Activated Sand Filter 7. Pressure Sand Filter 8. Final Collection Tank Treatment Process: Primary Treatment: Bar Screen: The effluent is screened before using mild steel grate bars. Any solid particles thus screened off shall be manually removed periodically and disposed through incineration or land filling. This process not only reduces COD but also prevents any damage to running motors. Secondary Treatment: Equalization Tank: The effluent contains sewage of ph ranging between 4-6. But for the biological treatment, a ph of 7 to 7.5 is most suitable. Depending on ph measurement using ph meter, required quantity of acid/base is added to the tank. Further it is taken for tertiary treatment. 14

16 The equalized wastewater is passed into an aeration/bioreactor tank. Aeration or Bioreactor Tank: The wastewater thus received in the aeration tank is treated by MBBR treatment in the chamber. The treatment plant will take suction from the pump well by its own feed pump. The pump is level controlled and has a capacity which is 2-3 times the average daily flow. The plant has therefore an intermittent working mode in terms of hydraulic flow, while the air blower supplying air to the bioreactors is continuously running. The biodegradation reactor comes in one or two stages depending on required cleaning efficiency. Plants with higher cleaning efficiency than % need a two-stage system. The bioreactors are degrading the dissolved organic matter by oxidation into carbon dioxide, which escapes to the air, and to biomass that acts as activated sludge. A suspended, free floating biofilm carrier medium is providing a large, protected biofilm surface for the bacteria and is simultaneously accumulating the active bio sludge inside the reactors. Settling & Sludge Removal: The biodegraded water is flowing into a tube settler where the suspended solid settles by gravity. The water is directed through a skim well to a plate settler system which provides the final clarification of the effluent. The sludge pump is activated each time the feed pump stops, with suction from the clarification stage. When necessary, the sludge is emptied by a vacuum truck and hauled away for external disposal. Tertiary Treatment: The treated water stored in the clarifier water tank is pumped through a dual media filter (Media: Activated Carbon & Graded Sand), where the color, turbidity and COD present will be completely minimized. The treated water is then collected in the final collection tank. Before reaching this tank, chlorine solution is dosed in to this water stream, with the help of a dosing pump, to disinfect as well as to digest any residual organic matters. The treated water so collected shall be pumped and used for gardening and irrigation. Also, the same water shall be used for back washing of filters. The back wash drain, filter rinse drain and the decanted water shall be pumped/drained back to the equalization tank Design Parameters Treated sewage quality at the outlet of the tertiary treatment plant details are given in Table below. Design Parameters S. No. Parameters Value 1 Treated Effluent BOD5 Less than 10 mg/l 2 Treated Effluent COD Less than 200 mg/l 3 Treated Effluent ph Around 6.5 to Treated Effluent Suspended solids Less than 10 mg/l 5 Oil and Grease Less than 10 mg/l 15

Ltd Solid waste collection systems comprise waste containers at ground floor of the building. The solid waste shall be disposed to the appropriate site as per municipal authority. The solid waste so generated shall be first segregated as plastic, glass, paper and other waste separately and disposed off as per MSW Rules, Energy Conservation To minimize the use of energy and to conserve the energy some of the energy efficient technologies are to be followed. Glazed windows are located to face the south to receive maximum sunlight in winter. To reduce heat losses during the night these windows are double glazed and have insulating curtains. Planning to bring maximum day light into a building and distributing it in a way that provides more desirable and better quality illumination than artificial light sources. This reduces the need for electrical light sources, thus cutting down on electricity use and its associated costs and pollution. Energy efficient lighting devices are planned such as Light Emitting Diodes (LEDs), CFLs, tube lights in place of incandescent bulbs. Solar panels will be kept in one third of the roof top area. 4.3 Green Belt Development Total green area measures sq. m. (0.564 Ac.). Only native vegetation with a mix of evergreen and deciduous trees shall be utilized to maintain seasonal greenery inside the complex in addition to flowering and ornamental plants. 18

20 5.0 POST PROJECT MONITORING Pollution monitoring program includes periodic analysis of air, ground water, soil and wastewater samples. Ground water and soil samples at representative locations within and nearby the project site will be periodically analyzed to detect contamination if any. In the event of any contamination, concerned authorities will be intimated immediately and appropriate corrective action in consultation with an approved technical agency will be initiated. 5.1 Monitoring Strategy The monitoring of various environmental parameters is necessary and is a part and parcel of the environmental protection measures. Monitoring is as important as that of control of pollution since the efficiency of control measures can only be determined by monitoring. A well-defined environmental monitoring program would be employed to monitor the environmental attributes to check whether they maintained within the permissible limits. The following Environmental attributes would be monitored: Air pollution and meteorological aspects. Water and waste water quality. Noise levels. Soil characteristics. Ecological preservation and up gradation. Maintenance of water conservation methods Maintenance & operation of STP Locations and frequency of monitoring would be as per the guidelines of TSPCB and MOEF. 5.2 Ambient Air Monitoring As per MOEF there is a need to identify 3 ambient air stations at 120 o angle keeping the main source in the center. The ground level concentrations of suspended particulate, Sulphur dioxide and nitrogen oxides in the ambient air outside the project boundaries and in the adjoining areas will be monitored at regular intervals. Any deviation from predicted/expected values will be investigated and necessary action will be taken. 19

21 5.3 Noise Monitoring Noise levels in the complex will be monitored periodically. If any deviation is observed necessary corrective measures will be taken. Monitoring noise levels is essential to assess the efficacy of maintenance of schedules undertaken to reduce noise levels and noise protection measures. A good quality sound pressure level meter is essential for this purpose. Noise surveillance is for the benefit of the wellbeing of staff and to keep track of sources. 5.4 Water Quality Monitoring Ground water near the project site will be routinely tested for its quality. No contamination of ground water and surface water is expected. However the water will be periodically tested for any change of water quality. The effluents/sewage coming out of the complex should be monitored regularly. Ground water is recommended to be monitored in at least two points in the direction of ground water flow to keep surveillance on the ground water quality. 5.5 STP The operations of STP are monitored to ensure the quality of treated water. The de-silting of sludge on regular basis needs to be ensured. 6.0 BUDGET FOR EMP The details of activities and expenses to be incurred on EMP are presented below. S.
