32 EMP for Kalpvan Green 1.4 Environmental Management during construction phase Construction phase results in temporary environmental pollution except for the permanent change in local land use pattern and aesthetics, in certain cases. Such pollution is mainly due to site preparation, civil works, transportation, storage & handling of different kinds of materials and construction worker sanitation etc. These are usually short-term impacts as compared to those during operational phase. Construction work shall take few months only. During this time, air pollution is expected in the form of increased suspended particulate matter concentration, due to site preparation, civil construction works and transportation of the various materials required complete construction of the proposed project. Temporarily dumping of excavating material and topsoil might be the aesthetics in the surrounding. Construction and installation work shall generate noise too. Dust will generate within working areas and measures will need to taken to protect workers. In order to mitigate the adverse environment impact due to the construction phase, regular sprinkling of the water will be recommended along with the construction activities. Various noise protecting measures are also suggested to mitigate the adverse effect on the workers Air Environment The main source of air pollution due to the proposed activities will be from the D.G. set & vehicular movements. However, D.G. set will be remained stand-by. The unit is also going to use low sulphur base fuel (HSD) for the D.G. set, therefore, the flue gas emission will be well within gaseous emission norms recognized by CPCB and there will not be any need of air pollution control measures except acoustic enclosures for the reduce of noise. However, in order to achieve the reduction of air emission, it is suggested that regular maintenance should be done to ensure proper atomization and subsequent minimization of any unburned combustibles Measures for fugitive emissions During the construction activities, there will be fugitive emission due to excavation, material handling etc and vehicular movements inside the residential complex. In order to mitigate the adverse environment impact 2

Adequate stack height will also be provided for proper dispersion of gaseous pollutants. As per the stipulated guidelines of Central Pollution Control Board for providing the stack height, following formula will be used. 5

36 EMP for Kalpvan Green Formula H = h+0.2x ÖKVA H = Total height of stack in meter h = Height of the building in meters where the generator set is installed However, in order to achieve the reduction, it is suggested that during operational phase regular maintenance should be done to ensure proper atomization and subsequent minimization of any unburned combustibles. The unit will also provide adequate stack monitoring facilities for the periodic monitoring of the stack to verify the compliance of the stipulated norms. In order to minimize the air pollution the unit will be developed green belt on and around its premises to considering the following guidelines, Green cover should be created at all the available open spaces. To make green belt dense more trees are to be planted at all patches where plantations already exists. Strict surveillance is made to increase the survival rate of the trees. Plants with higher height, medium and low height should be planted to ensure thick belt for attenuation of fugitive emission. This activity demands expert advice and guidance Measures for fugitive emissions There will not be any chance of fugitive emission except vehicular movements inside the residential township. However, the residential township also proposes to provide pacca road inside the complex and vacate space covered by land scalping. The unit has adopted following measures, which will be continued after proposed expansion. Regular maintenance of roads, and greenbelt development activities Water Environment The total fresh water requirement for the proposed project will be 222 Kl/day. The entire quantity of fresh water demand will be satisfied through RMC/RUDA water supply. Therefore, there will not be any impact on ground water table due to proposed project. Minimization of the water consumption: Duel plumbing will be provided for flushing of recycled treated water. 6

37 EMP for Kalpvan Green Storm water and rain water management plan: The rain or storm water occurring over entire plot is required to be collected and drained off into nearby city rain water or into a lake or sea as available. It is necessary to drain-off the rain water for the following reasons: This may injurious for healthy life of population, in case of stagnant of water. The first showers, particularly when it is after a long dry spell are foul because these contain several organic material like animals dung and other waste matter from stables, market places, open court yards and streets etc., quick removal of storm is important. By doing so, minimize the storm water drainage load to avoid water logging locally as well as larger scale. We have proposed to provide percolation well for rainwater harvesting in which rain water collected from roof and other open spaces during monsoon seasons. However, developer will create percolating well as per the RMC /RUDA guideline. Percolation well is connected with storm water channel where excess water from well will be drained out to storm water channel. Drawing also shows even slope though out the plot for proper channel or route of water to channel. We also proposed oil and grease and sub silt trap. The rain water will be harvested and will be used ground water recharging. Before doing so, a pre-treatment shall be provided by way of trap. This will have a suspended baffle to arrest oil & grease and sub silt, grit and ash. A tee pipe shall be provided at the outlet end to control the level in such a way as not to allow escape of oil & grease. Foot walls to facilitate worker to go down for de-silting. Management of wastewater:- The object of wastewater treatment is to remove pollutants from the waste and to bring the quality of effluent to a desired standard. Treated wastewater will be further used for flushing/gardening and balance will be disposed to RMC/RUDA drainage. Hence, this will help to reduce the fresh water requirement from the source. Sewage treatment plant Flow diagram of STP is self explanatory. There are three type of treatment which is required for following purpose: 7

38 EMP for Kalpvan Green Primary treatment: consists of sedimentation only. This removes the 45 to 60% of suspended solids. 30 to 45% BOD and 40 to 60% of total coliforms Secondary treatment: is biological treatment which removes 75 to 95% of suspended solids, 70 to 97% BOD and 80 to 98% of total coliform. Tertiary treatment: is polish the effluent received from secondary treatment and improves the quality for further reuse. Following shall be the Output Effluent Characteristics as per IS 2490 Standard: (Reuse for flushing and landscaping. Tertiary Treatment is required) ph 7-8 Total Suspended Solids (TSS) Total Dissolved Solids (TDS) < 30 ppm < 2100 ppm Biochemical Oxygen Demand (BOD) < 20 ppm Chemical Oxygen Demand (COD) Oil & Grease < 50 ppm < 5 ppm Solid Waste Management During the operational phase, Domestic solid waste and bio-sludge will be generated. No hazardous waste is expected from the proposed project except used lube oil from D.G. Sets and it will be sold to registered recyclers. The domestic sludge will be collected scientifically and disposed off at RMC secured landfill site. The bio-sludge obtained from the STP shall be used as manure for in-house gardening & plantation.

39 EMP for Kalpvan Green Noise Environment: During the operational phase of the project, noise will be generated from various sources. Some major sources of noise generation at the project site are listed here: Generation of noise from the DG sets, Inside vehicular movements, DG sets shall be provided with acoustic enclosures to control the noise levels. Noise Control Technique The main source during the operation will be D.G. sets, vehicular transportation and water transferring pumps. However, to minimize the noise pollution the unit proposes the following noise control measures, DG sets shall be provided with acoustic enclosures to control the noise levels The member of complex & guest shall be informed to avoid unnecessary speeding of the vehicles inside the premises. Extensive oiling, lubrication and preventive maintenance will be carried out for the lifts & pumps to reduce noise generation. The selection of water pump will be made with specification of low noise levels. The green belt area will be developed within complex and around the periphery to prevent the noise pollution in surrounding area. Monitoring of noise levels is essential to assess the efficacy of maintenance schedules undertaken to reduce noise levels and noise protection measures Parking managements There is separate entry & exit provision. Adequate provision will be kept for car parking in the project. Car parking will be provided at Basement. Other parking is provided on the surface area & hollow plinth.

It also causes aesthetics improvement of the area as well as sustains and supports the biosphere. Plantation around the pollution sources control the air pollution by filtering the air particulate and interacting with gaseous pollutant before atmosphere. In green belt area about 1000 trees per hector of land shall planted. The selection of tree species suitable for plantation at the complex shall be governed by following factors, The trees should be tolerant to air pollutants present in the area The trees should be able to grow and thrive on soil of the area, be evergreen, inhabitant, having minimum of leaf fall. The trees should be tall in peripheral curtain plantation and with large and spreading canopy in primary and secondary attenuation zone It is also recommended to plant few trees, which are sensitive to air pollution as air pollution indicator. The developer proposes to develop the green belt & landscape which will be more than 10 % of total plant area Health & Safety Sanskara Conbuild Pvt. Ltd. intend to adopt occupational health program right from the start of production. Health hazards associated with occupation are called occupational hazard. The following check-ups shall be carried out regularly to avoid occupational hazard, Pre-employment medical check-up at the time of employment 10
