9 Environmental Impact Assessment Report Proposed Residential & Commercial Development 1.4 Current land use and ownership Currently the site is a vacant land. This project is a development project and there are no litigation pending against the proposed project. 1.5 Objectives of the EIA study The purpose of Environmental Impact Assessment (EIA) is to assist in the decision making process and to ensure that the projects under consideration are environmentally sound and sustainable. EIA identifies the ways of improving project environmentally by preventing, minimizing, mitigating or compensating for adverse impacts. Urban development projects including housing and office complexes do have the potential in altering environmental resources of any urban area. They cause stress on local environmental assets of the urban area and could become the potential source for limiting the growth of the city. Unplanned construction and operation of such projects usually result in impacts on various facets of Environment keeping above issues under considerations, an Environmental Impact Assessment (EIA) study is conducted which incorporates into development and planning process, a plan for environmental protection and conservation. The procedure identifies the possible positive and negative impacts on the environment likely to emanate as a result of construction and operation of a project. The EIA thus, provides for a plan which, upon implementation, will reduce or offset the negative impacts of a project resulting in a minimum level of environmental degradation. This minimization may be a result of implementation of a project modifications or environmental protection measures which simply reduces the severity or number or magnitude of negative impacts. The plan may also result in utilization of positive impacts for enhancement measures which offset negative impacts. To measure the level of plan implementation and the degree of effectiveness of the above environmental protection provisions, the EIA provides a monitoring programme. This programme is so designed that it identifies the parameters of uncertainty and measures the related impacts. It is necessary that there is close integration of EIA with various aspects of a project including financial and engineering aspects which ensures environmental consideration are given due weight in project selection, siting design and operation.

10 Environmental Impact Assessment Report Proposed Residential & Commercial Development Analysis of past experiences indicate that it is necessary to examine a number of problem areas in order to ensure that environmental concerns can be effectively integrated in the development process. Similar approach has been adopted while conducting the EIA study for the proposed residential apartment and commercial complex. 1.6 Stages in the EIA Study The purpose of this section is to itemize the methodology for Environmental Impact Assessment (EIA) which has been followed for this study. Any activity relating to construction and operation is expected to cause impacts on surrounding environment. The impacts may be adverse or beneficial, short term or long term, and reversible or irreversible. In order to assess the significance of impacts, various steps that are used in conducting an EIA within core and buffer zone around the proposed project construction site are divided into the following phases: Identification of significant environmental parameters and assessing the existing status within the impact zone with respect to air, water, noise, land, biological, and socioeconomic components of environment. Study of various activities of the proposed project components to identify the areas leading to impact/change in environmental quality. Identification of potential impacts on various environmental components due to the activities envisaged during pre-construction, construction, and operational phases of the proposed project. Prediction of significant impacts on the major environmental components using qualitative / quantitative techniques. Preparation of environmental impact statement based on the identification, prediction and evaluation of impacts. Delineation of environmental management plan (EMP) outlining preventive and curative strategies for minimizing adverse impacts during pre-construction, construction and operational phases of the proposed project. Formulation of environment quality monitoring programme for construction and operational phases to be pursued by the project proponent. The environmental impact assessment in India was started in the year when the Planning Commission asked the then Department of Science and Technology to M/s.

11 Environmental Impact Assessment Report Proposed Residential & Commercial Development examine the river-valley projects from environmental angle. This was subsequently extended to cover those projects, which required approval of the Public Investment Board. These were administrative decisions, and lacked the legislative support. The Government of India enacted the Environment (Protection) Act on 23rd May To achieve the objectives of the Act, one of the decisions that were taken is to make environmental impact assessment statutory. After following the legal procedure, a notification was issued on 27th January 1994 and subsequently amended on 4th May 1994, 10th April 1997, 27th January 2000, 7th July 2004 and 14th September 2006 making environmental impact assessment statutory for 32 projects /activities. This is the principal piece of legislation governing environmental impact assessment. As per the EIA Notification, 14th September 2006 published in the Gazette of India, Extraordinary, Part- II and Section-3, Sub-section (ii) Ministry of Environment and Forests, proposed project is listed as Category B1 as per Item No.8 (b) mentioned in the schedule (Covering an area = 50 ha and or built up area >/= 1,50,000 Sq. mtrs). So, the category B1 Projects requires preparation of EIA Report. In order to get an idea about the existing state of the environment, various environmental attributes such as meteorology, air quality, water quality noise level, soil quality, ecology and socio-economic environment were studied / monitored. Details of Flora and fauna were identified in the study area comprising of core and buffer zone for identification of existing species and classifying them as per Wildlife (Protection) Act, Applicable Environmental Regulations and Standards With respect to prevention and control of environmental pollution, the following Acts and Rules of Ministry of Environment and Forest, Government of India govern the proposed project: 1. Water (Prevention and Control of Pollution) Act, 1974 as amended in 1978 and Air (Prevention and Control of Pollution) Act, 1981 as amended in Environment (Protection) Act, 1986 amended 1991 and Environment (Protection) rules, 1986 and amendments thereafter 4.

22 Environmental Impact Assessment Report Proposed Residential & Commercial Development SEWAGE TEATMENT PLANT (STP) TECHNOLOGY SBR The sewage from the inspection chamber shall be conveyed through the external sewerage network of the project and finally disposed into the sewage treatment plant. The capacity of the sewage treatment plant is worked out to be 475 cum. The approximate space required for the STP will be 650 SQM. STP shall be constructed totally below ground with an accessible stair case to reach the pump. The STP below the ground requires mechanical ventilation. The objective of sewage treatment is to stabilize decomposable organic matter present in sewage so as to produce an effluent and sludge, which can be disposed of in the environment without causing health hazards or nuisance. The degree of treatment to be adopted should not only meet the requirement of regulatory agencies but also result in the maximum use of tertiary treated sewage consistent with economy. Extended Aeration with sequential batch reactor technology is proposed. SEQUENTIAL BATCH REACTOR The process of BOD removal, nitrification/de-nitrification, phosphorus removal and sludge separation are achieved continuously in a single SBR tank. The process operates on the continuous inflow and batch outflow principle. The phases of aeration, settling, decantation occur sequentially and are controlled by a PLC. The tank is divided into pre-aeration and main aeration tanks by a baffle wall with openings at the bottom. The sewage flows continuously into the pre-aeration tank, which acts as a biological selector enhancing the growth of the most desirable organisms while limiting the growth of the filamentous bacteria. Sewage from pre-aeration tank flows through openings at the bottom of the baffle wall and into the main aeration tank where BOD removal and nitrification occur. After aeration phase, sludge separation occurs in the settling phase. After settling, the clear water from top is removed through a PLC operated decanter. Denitrification occurs during anoxic periods of settling and decanting phases. The excess sludge is wasted during decant phase. M/s. Salarpuria Properties Private Limited Page 21 of 105

23 Environmental Impact Assessment Report Proposed Residential & Commercial Development The SBR treated water is disinfected using sodium hypochlorite and filtered through a pressure sand filter. The final treated water will be stored for recycling for gardening purpose. The waste sludge is used as manure after dewatering through filter press. It is recommended to provide ultra-filtration after the tertiary treatment to bring down the BOD content less than 5 ppm. The efficiency of a treatment plant depends not only on proper design and construction but also on good operation and maintenance. The Characteristics of Raw sewage shall be as follows ph = 6-7 TSS = 400 mg / L BOD5 = mg / L COD = mg / L Characteristic of Treated sewage shall be as follows ph = 7-8 TSS = 10 mg / L BOD5 = 5 mg / L COD = 30 mg / L DISPOSAL OF TREATED SEWAGE After the treatment the tertiary treated sewage shall be reused for landscaping, vehicle & floor washing, HVAC makeup.

27 Environmental Impact Assessment Report Proposed Residential & Commercial Development sewerage network of the project and finally disposed into the sewage treatment plant. The capacity of the sewage treatment plant is worked out to be 160 cum. The approximate space required for the STP will be 200 SQM. STP shall be constructed totally below the ground with an accessible stair case to reach the pump. STP provided below ground shall require mechanical ventilation. The object of sewage treatment is to stabilize decomposable organic matter present in sewage so as to produce an effluent and sludge, which can be disposed of in the environment without causing health hazards or nuisance. The degree of treatment to be adopted should not only meet the requirement of regulatory agencies but also result in the maximum use of end products consistent with economy. Extended Aeration with sequential batch reactor technology is proposed. SEQUENTIAL BATCH REACTOR The process of BOQ removal, nitrification/de-nitrification, phosphorus removal and sludge separation are achieved continuously in a single SBR tank. The process operates on the continuous inflow and batch outflow principle. The phases of aeration, settling, decantation occur sequentially and are controlled by a PLC. The tank is divided into pre-aeration and main aeration tanks by a baffle wall with openings at the bottom. The sewage flows continuously into the pre-aeration tank, which acts as a biological selector enhancing the growth of the most desirable organisms while limiting the growth of the filamentous bacteria. Sewage from preaeration tank flows through openings at the bottom of the baffle wall and into the main aeration tank where BOD removal and nitrification occur. After aeration phase, sludge separation occurs in the settling phase. After settling, the clear water from top is removed through a PLC operated decanter. De-nitrification occurs during anoxic periods of settling and decant phases. The excess sludge is wasted during decant phase. The SBR treated water is disinfected using sodium hypochlorite and filtered through a pressure sand filter. The final treated water will be stored for recycling for gardening purpose. The waste sludge is used as manure after dewatering through filter press. M/s. Salarpuria Properties Private Limited Page 26 of 105

The efficiency of a treatment plant depends not only on proper design and construction but also on good operation and maintenance. The Characteristics of Raw sewage shall be as follows ph = 6-7 TSS = 400 mg / L BOD5 = mg / L COD = mg / L Characteristic of Treated sewage shall be as follows ph = 7-8 TSS = 10 mg / L BOD5 = 5 mg / L COD = 30 mg / L DISPOSAL OF TREATED SEWAGE After the tertiary treatment the recycled water will be used for toilet flushing, landscaping and make up water for air conditioning systems. 2.5 DESCRIPTION OF CIVIL WORKS 1 Screen Chamber x 0.6 x 1.5m SWD RCC 2 Oil & Grease Chamber x 0.6 x 1.2m SWD RCC 3 Equalization tank x 4.5x 3.0m SWD RCC 4 Pre-aeration Tank 1 5.0x 4.5 x 3.0m SWD RCC 5 Drain Sump x 1.0 x 1.0m SWD RCC 6 SBR Tank x 5.0 x 3m SWD RCC 7 Decanter x 5.0 x 2.0m SWD RCC 8 Sludge Holding Tank x 1.5 x 3.0m SWD RCC 9 Final sump 1 8.0x 5.0X3.0m SWD RCC 10 Foundations for Static equipment pumps, blowers, railings, staircases, interconnecting, drain channel etc 1 lot As required Suitable M/s.

31 Environmental Impact Assessment Report Proposed Residential & Commercial Development The material used for construction of building will be of non combustible in nature. Non combustible material will only be used for the construction / erection of false ceiling including all fixtures and used for its suspension / erection etc. and of low flame rating. Fossil fuels, such as diesel fuel, gasoline and oil will be used during the construction and operation of the project for mechanical and electrical equipment s. Electricity will be used during construction to provide power to construction equipment and during operation for lighting of buildings and running utility equipments. Electricity consumption will be kept at a minimum when possible by adopting electricity conservation measures. 2.6 Solid, liquid and gaseous wastes generation. Solid waste During construction phase Dust generated during the construction phase from earthworks, movement of vehicles and by wind erosion of areas cleared of vegetation. The degree of dust generated would depend on the soil compaction and moisture content of the ground surface during construction. The generation of waste material is inevitable during the construction phase of the development. Waste materials normally include general refuse including scrap metal, cardboard, plastics, inert waste including excess fill and building rubble and sewage wastes from the construction workers housing. Domestic sewage will be generated during the operation phase of the project which will be treated in the proposed STPs. Significant proportion of solid wastes will be generated from residential apartment and commercial complex will need to be properly managed and disposed off safely. The sludge generated from STP will be reused in horticulture within the project site. Table 2.6 Solid Waste Generation Operation Phase: SI.No. Parameter Details 1.

33 Environmental Impact Assessment Report Proposed Residential & Commercial Development Chapter 3 Description of the environment 3.0 Introduction: The study area covers 10 km radius around the project site in Pantharapalya Village, Kengeri Hobli, Bangalore South Taluk, Bangalore, Karnataka State. The study area of 10 km radius around project is covered in survey of India topo sheet no 57 H/9, 57 G/12, 57 G/8, & 57 H/5 (1:50,000). The baseline environment quality represents the background scenario of various environmental components in the study area. As a part of Environmental Impact Assessment study, baseline environmental monitoring was carried for season of 2015 covering the months of March, April and May. The main objectives of characterization are as follows: To assess the existing baseline status of air, water, noise, land, biological and socioeconomic environments within the project site and around 10 km radius of the study area. To identify and quantify significant impacts due to the proposed activity on various environmental components through prediction of impacts. To evaluate the beneficial and adverse impacts of the proposed activity. To prepare an Environmental Management Plan (EMP) detailing control technologies and measures to be adopted for mitigation of adverse impacts if any, as a consequence of the proposed activity. To prepare a post project monitoring programme for checking and regulating the environmental quality of the project and support in sustainable development of the area. 3.1 Methodology of EIA Any developmental activity is expected to cause impacts on surrounding environment during the construction and operation phases. The impacts may be adverse or beneficial. In order to assess the impacts due to the proposed activity, an Environmental Impact Assessment study has been conducted within an area of 10 km radius around the project site. The various steps involved in Environmental Impact Assessment study are divided into the following phases M/s. Salarpuria Properties Private Limited Page 32 of 105

34 Environmental Impact Assessment Report Proposed Residential & Commercial Development Identification of significant environmental parameters and assessing the existing status within the impact zone with respect of air, water, noise, soil, biological and socioeconomic components of environment. Prediction of impact on air quality taking into consideration the proposed emissions to project the overall scenario Prediction of impact on water, land, biological and socio economic environment Evaluation of total impacts after superimposing the predicted scenario over the baseline scenario to prepare an environmental management plan. The methodology adopted for studying the various individual components of environment is described below Micro meteorology An auto weather monitoring station installed in Bangalore city hence secondary data has been collected through IMD. Meteorological parameters such as wind speed, wind direction, maximum, and minimum temperatures, Relative humidity, cloud cover, recorded on hourly basis continuously covering the entire months from March 2015 May Wind speed & wind direction data recorded during the study period were used for computation of relative percentage frequencies of different wind directions, details of which is below table. The meteorological data thus collected has been used for interpretation of the existing ambient air quality status and the same data has been used for prediction of impacts of future scenario due to the activities of the proposed scheme. A meteorological data was collected through secondary source. The predominant wind direction was found to be from West & East direction, below figure 3.1 gives the wind rose diagram for the same details of the metrological date is enclosed in the EIA Report.

The monitoring network was so designed such that representative samples are obtained from the upwind direction, down wind and cross wind directions of the proposed project site. These monitoring sites have been established keeping in view the available climatologically norms of predominant wind direction and wind speed of this particular region. The following points were also taken into consideration in designing the network of sampling stations: 1. Topography/ Terrain of the study area 2. Populated areas within the study area 3. Residential and sensitive areas within the study area. 4. Magnitude of the surrounding industries 5. Representation of regional background levels 6. Representations of cross sectional distribution in downward direction. The existing Ambient Air Quality status (AAQ) has been monitored for PM2.5, PM10, SO2, NOx and CO. PM2.5 & PM10 at each station has been monitored on 24 hourly basis and all the gaseous sampling has been done on 24 hourly basis except CO, which was monitored on 8 M/s. Salarpuria Properties Private Limited Page 35 of 105

37 Environmental Impact Assessment Report Proposed Residential & Commercial Development hourly basis. The suspended particulate matter present in the ambient air was also analysed for the presence of poly-aromatic hydrocarbons (PAH). Pre-calibrated respirable dust samplers have been used for monitoring of the existing AAQ status. Methodologies adopted for sampling and analysis were, as per the approved methods of Central Pollution Control Board (CPCB). Maximum, minimum, and percentile values have been computed from the raw data collected at all individual sampling stations to represent the ambient air quality status of the study area. Design of ambient air quality monitoring network The following criteria were taken into account in designing the ambient air quality monitoring network. Topography/terrain of the study area Populated areas within the region Prediction of maximum concentrations and distances of their likely occurrences under prevailing micro-meteorological conditions. Representation of regional background. Representation of valid cross sectional distribution in down wind direction. Historical wind rose to understand the wind pattern in the area. Reconnaissance Reconnaissance survey was undertaken within the study area to collect information regarding topography of the study area, meteorological features of the area and other features relevant to the air environment. Reconnaissance survey enables the selection of sampling sites and design of air quality monitoring network. The criteria pollutants like SPM/RSPM, SO2 and NOx were identified to assess the existing air quality in the impact zone. The study area was limited to 5 Km radial distance from the proposed project site. Five ambient air quality monitoring sites were selected along with the project site based on the ambient air quality monitoring network design. M/s.

38 Environmental Impact Assessment Report Proposed Residential & Commercial Development Ambient air quality scenario in Bangalore Bangalore s air pollution problem has not been characterized. However, based on monitored data that has not passed through data quality check measures (control and assurance), the Central Pollution Control Board (CPCB) identifies Bangalore as one of the many Indian cities where TSP and PM10 levels exceed the INAAQS almost by a factor of three, and attributes the PM10 problem to the vehicular emission without support of a scientific study (CPCB Annual Report 2002). But, levels of SO2 and NOx have generally decreased over the last five years. The Karnataka State Pollution Control Board (KSPCB) monitors air quality at three different places in Bangalore midtown, on the south-western side and on the north-eastern side and according to their published data the average of the annual mean concentrations of NOx, SOx, PM10 and TSP monitored at the three stations for the year is 13, 24, 58 and 130 μg/m3, respectively. For all criteria pollutants the concentrations are within the INAAQS, although for PM10 and TSP, the levels are barely within the INAAQS and, therefore, a matter of concern. Organic air pollutants, known as Air Toxics in the U.S., are not monitored in Bangalore, and hence, the KSPCB has no data available on the ambient levels of benzene, formaldehyde, 1-3 butadiene, polycyclic aromatic hydrocarbons (PAHs), etc. But, open-air riders in the city are exposed to suffocating noxious air that gives irritating throat and burning eyes. The CPCB and KSPCB analyse the data in terms of annual averages. Since arithmetic averages are gross representations of the underlying data it is probable for several daily exceeds to go unnoticed when analysing data with only annual averages. Standard deviation, which indicates the extent of variation in the data, if provided might have somewhat helped to understand the data better, but it is not provided. In the absence of fine resolution data, data analysis is based on annual averages. Based on the data published by KSPCB concentrations of SO2 has continuously decreased since the last five years indicating that the control measures adopted against reducing SO2 emissions have been rewarded richly. On the contrary, NOx and TSP reach peak levels in and have steadily decreased since then. NOX levels have been below the INAAQS (NOX: 60 µg/m3) during this period, while the TSP levels have been greater than the INAAQS (TSP: 140 µg/m3) except during PM10 monitoring started in and has M/s. Salarpuria Properties Private Limited Page 37 of 105

39 Environmental Impact Assessment Report Proposed Residential & Commercial Development remained about the same (~60 µg/m3) for the last three years, which is also the INAAQS level for PM10. TSP and PM10 levels over Bangalore are clearly of concern. Table 3.2 Sampling Locations for Ambient Air Quality monitoring Sl.

53 Biological environment Study of biological environment is one of the most important aspects for Environmental Impact Assessment, in view of the need for conservation of environmental quality and biodiversity. Ecological systems show complex inter-relationships between biotic and abiotic components including dependence, competition and mutualism. Biotic components comprises of both plant and animal communities which interact not only within and between themselves but also with the abiotic components viz. Physical and Chemical components of the environment. Generally, biological communities are the good indicator of climatic and edaphic factors. Studies on biological aspects of ecosystems are important in environmental impact assessment for safety of natural flora and fauna information on the impact of environmental stress on community structure serves as an inexpensive and efficient early warning system to check the damage to a particular ecosystem. The biological environment includes mainly terrestrial ecosystem and aquatic ecosystem. An ecological survey of the study area was conducted particularly with reference to recording the existing biological resources. Secondary data was collected from forest department Flora The general vegetation along road and agricultural lands is primarily due to plantation of both exotic and native species of trees having commercial importance. Some of the commonly encountered species along the road side are Azadirachta indica, eucalyptus, Acacia auriculiformis and Prosohis juliflora. A list of flora in the 10 Km radius of the study area is given in the EIA Report Fauna Domesticated animals of the area include Cattle, Buffaloes, Goats, Cats, Dogs etc. Cows and Ducks are also common. No endangered faunal species are found in the proposed project area Socio-economic and health environment M/s. Salarpuria Properties Private Limited Page 52 of 105

54 Socio-economic environment includes description of demography, available basic amenities like housing, health care services, transportation, educat0ion and cultural activities. Information on the above said factor has been collected to define the socio-economic profile of the study area (10 km radius), which is also a part of Environmental Impact Assessment study for the project. A detailed socio-economic survey was conducted covering all villages in the 10 km radius from the project site. The information of socio-economic aspects has been compiled from various secondary sources including various government and semi-government offices. Summary of the study is given as below: The total population of study area is 3, 60,092 with a sex ratio of Male and Female is 1.1:1.

56 Chapter 4 Anticipated Environmental Impacts 4.1 Introduction This section identifies and predicts the potential impacts on different environmental components due to the construction and operation of the proposed project. It details all the potential impacts on biophysical and socio-economic components of the local environment due to the proposed activities and sub-activities. Prediction of impacts is the most important component in the Environmental Impact Assessment studies. Several qualitative and quantitative techniques and methodologies are used to conduct analysis of the potential impacts likely to accrue as a result of the proposed development activities on physical, ecological and socio-economic environment. Such predictions are superimposed over the baseline (pre-project) status of the environmental quality to derive at the ultimate (postproject) scenario of environmental conditions. The prediction of impacts helps to minimize the adverse impacts, maximize the beneficial impacts on environmental quality during pre and post project execution. The proposed project would create impacts on the environment in two distinct phases: During the construction phase which may be regarded as temporary or short term The activities that take place during construction phases of the project are levelling of site, construction and erection of buildings, if any etc., and associated equipment in operation. The potential primary and secondary impacts on the environment, their prediction, significance and mitigation are figured out. The other during the operation stage which would have long term effects The potential significant impacts are on topography, land use, soil quality, ambient air quality, noise levels, traffic densities, water resources, water quality, biological environment, demography and socio-economics. The environmental impacts in this section have been discussed separately for the construction phase and the operation phase of the proposed project. The environmental impact assessment approach used to evaluate the proposed project comprises of three sequential elements. These are impacts identifying, prediction and evaluation. The first step of the impact assessment process involves identifying the key issues associated with the construction and operation phases of the project. Issues and concerns of the proposed project are scoped based on the M/s. Salarpuria Properties Private Limited Page 55 of 105

57 knowledge and experience with respect to environmental setting and project elements. Accordingly, the existing environmental system is described and the components of the project are determined. This step involves identification of the environmental modification that may be significant, forecasting of the quality and spatial dimension of change in the environment identified and estimation of the probability that the impact will occur. This step involves determination of the incidence of benefit to user groups and population affected by the project, specification and comparison of effects between various alternatives and assessment of the likely effect of the project on the environmental, economic and social components indicating the nature of effects. 4.2 Impacts on Ambient Air Environment The potential ambient air quality impacts arising from the proposed project would occur mainly during project construction phase. Construction phase would involve site clearances and preparation, infrastructure development, building construction etc., PM10 would be the predominant pollutant generated from construction activities. The gaseous emissions such as SO2, NOx and CO would be generated from the construction equipments and vehicles. During operation phase, DG sets would be the only point source of emission. The ambient air quality monitoring results show that the concentrations at most of the locations within the core zone of the proposed project site are within the norms prescribed. Adequate stack height for DG sets will be provided as per norms. However, appropriate mitigation measures would still be employed during the construction stage to reduce any incremental rise in pollution level to an acceptable limit. Monitored values of SO2, NOx and CO in the ambient air are well within the limits indicating low pollution level (L) as per the CPCB criteria Impacts during construction During construction, the project would have two major impacts on ambient air quality due to an increase in gaseous emissions by heavy construction machinery and vehicles and an increase in dust by construction activities. Earth excavation work, foundation work, superstructure work, material storage, transportation and handling of construction materials, and wind erosion are the major factors that would produce a temporary, localized increase in SPM and RPM levels. The increased movement of heavy vehicles carrying construction materials, operation of DG sets as standby power back up system would generate gaseous emissions. The degree of dust generated would depend on the soil compaction and moisture M/s. Salarpuria Properties Private Limited Page 56 of 105

58 content of the ground surface during construction. Dust and exhaust particulate emissions from heavy equipment operations would temporarily degrade air quality in the immediate construction zone. The increase in air particulates would be minimized by the performance of the work. The construction contractor will visually monitor dust levels on the site during construction. Dust suppression will be instituted, using water tankers mounted on tractors, sprinklers and other means as necessary, in the event that high levels of dust are observed strong winds and dry conditions make dust generation likely, and complaints about dust are received. Further GI Sheets will be put up all around the site so as to avoid dusts & the stack for discharging the emission from the DG sets shall be installed up to recommended height prescribed by CPCB Impacts during operation The project site would be expected to have an impact on air quality during their normal operation. Only through point source of emission that will be, DG sets installed as standby power supply system to meet the power requirement during emergencies. It is proposed to install individual stacks of adequate height to exhaust the DG emissions. The stacks of adequate height will be provided from above the roof of the building as per the norms. Vegetation buffers can minimize the built-up of pollution levels in urban areas by acting as pollution sinks. Since low sulphur diesel will be used, very small quantity of Particulate matter, SO2, NOx and CO will be generated during the combustion process. Also, during the operation phase of the project, the impacts on air quality due to vehicular emissions in the project will be very less as the project will not result in generation of any large volume of traffic. It is for these reasons that the ambient air quality predictions using models have not been carried out. 4.3 Impacts on Ambient Noise Environnent Impacts during construction During construction phase, there will be short-term noise impacts in the immediate vicinity of the project site. Construction activities will include operation of DG sets, concreting, mixing, excavation activities & vehicular movement. Barricades put up around the site will control the noise level to a great extent. M/s. Salarpuria Properties Private Limited Page 57 of 105

59 4.3.2 Impacts during operation The only source of noise pollution during operation phase is the DG sets for which acoustic enclosures will be provided. 4.4 Impacts on water environment Impacts on ground water The water requirements during operation will be met through BWSSB supply. Recharging of ground water will be carried out. The following measures are taken to achieve recharging Well-designed storm water network to collect the rain water from the site area and water collected is diverted to the proposed rainwater harvesting pits for recharging the ground water. All efforts will be done to conserve water in the complex to comply with the standards of water conservation practices. Ground water quality shall be periodically monitored and records shall be reviewed and analysed on regular basis Impacts on piped water supply During operation Based on projects and also referring to the regulations of National Building Code, the average per capita water consumption is assumed as below: Total No. of Units = 850 Nos. Total Water Requirement = 780 KLD ( ) Domestic water Requirement = 513 KLD Flushing Requirement = 267 KLD Total quantity of wastewater generated = 624 KLD Treated Waste Water Generated = 570 KLD Sewage Treatment Plant (STP) to be provided = Sewage Treatment Plants of capacities 475 KLD & 160 KLD. The sewage generated during the operation phase will be treated up to the tertiary level in Sewage Treatment Plant (STP). The entire treated sewage will be recycled/ reused for toilet M/s. Salarpuria Properties Private Limited Page 58 of 105

60 flushing, landscaping and for HVAC in the project site, excess will be discharged into existing sewer line during rainy season Impacts due to wastewater generation Details of wastewater treatment; The sewage from the inspection chamber shall be conveyed through the external sewerage network of the project and finally disposed into the respective Sewage Treatment Plants. The object of sewage treatment is to stabilize decomposable organic matter present in sewage so as to produce an effluent and sludge, which can be disposed of in the environment without causing health hazards or nuisance. The degree of treatment to be adopted should not only meet the requirement of regulatory agencies but also result in the maximum use of end products consistent with economy. Sequential Batch Reactor along with Ultra-filtration will be adopted for treating the sewage. 4.5 Impacts on land environment Impacts on land use The proposed project will not alter the land use pattern of the proposed site. The site, after completion of its development, would consist of build - up structure neatly landscaped, leading to a pleasant outlook. Plantation of trees in the open spaces would add a different dimension to the existing landscape of open vacant lands and would provide a visual comfort Impacts on soil As the topography in and around the site is mostly plain with minimum slope, the digging of the site before the start of the construction work for the foundation work would not result any significant effect on soil erosion and silt run off, even during the heavy rains. The project doesn t requires extensive work on the excavation and removal of soil and hence will temporarily affect soil structure and stability localized. The project proponent will adopt good construction practices that will ensure the environmental impacts of waste effluents generated on-site during construction will be minimized Construction wastes Quantity of Construction Debris expected & it s Disposal = 706 cum Quantities of Earthwork involved in construction activity-cutting, filling, reclamation etc M/s.

61 Total earth/soil (including top soil) = Cum. Backfilling to be done between foundations = 6300 cum. Backfilling to be done on the backside of retaining walls & underground tanks = 7200 cum. Filling done to fill up the low lying areas at site = cum. Top soil to be used for landscape development = cum Solid wastes generation and disposal During operational phase, the solid waste generated from the proposed project will be of non-hazardous in nature consisting of biodegradable and non-biodegradable wastes. The total solid waste generated is about 2637 Kgs /d (1747 Kgs/day residential Kgs/d commercial). The solid waste will be segregated into organic and inorganic waste at the source itself in which organic waste will be treated in the Organic waste converters and inorganic wastes will be sold to the authorized recyclers. Dewatered/ dried sludge from STP 14 kg/day-dry weight will be used as manure in horticulture. SI.No. Parameter Table: 4.1 Details of solid waste generation 1.

62 4.6 Impacts on socio economic environment Hazards to construction workers and the local population The proposed facility will not generate any hazardous waste except used oil from the DG Sets. However, the waste oil from the DG Sets will not be discharged in any open area. However, the quantity stored will be below the threshold limit specified by the MSIHC rules and handed over to the KSPCB authorized vendors for re-processing. Hence there is absolutely no threat to the area and the neighbouring area due to the hazardous waste i.e. waste oil Housing and transportation of construction workers Labourers are going to be outsourced from nearby area. Facilities like toilets, drinking water are provided for labourers at the construction site. There is good road network connecting the site which helps in transportation Socio cultural impacts The project will contribute only marginally to the socio-economic development of the area at the local level. The land values around the project site are likely to be increased after the operation of the project. The direct and indirect employment to the local population during the operation of the project at both skilled and unskilled levels will benefit the local population and its specific groups. Economic activity will get a boost for small shopkeepers, vendors and hence have a positive impact Impacts on physical infrastructure It does not have any impact on the surrounding physical structures. Run off from building areas during rains will be utilized for harvesting and recharge of ground water. Appropriate water conservation measures will be adopted in regular activities. Vegetative barriers along the site boundary will act as a noise barrier. The domestic sewage generated from the project will be linked to STP being set up on-site. The treated water will be reused for flushing of toilets, landscaping, (Horticulture), car washing, HVAC etc., hence will reduce the fresh water consumption for the same activity. M/s.

63 4.6.5 Employment opportunities A sizeable workforce comprising skilled, semi-skilled and unskilled labours will be needed during construction phase as well as operation phase. Significant number of semi-skilled and unskilled labourers will be recruited from the nearby areas. This will create some employment opportunities in the area. Since most of the sizeable labour force will be drawn from neighbourhood, no new environmental problem is anticipated. Moreover, this project will provide employment to approx. 300 local labours in the construction phase. Thus, the proposed project is supposed to have major beneficial impacts. 4.7 Renewable resources Potential adverse effects from the use of renewable resources are associated with the construction of the project components that will require the use of renewable and nonrenewable resources including wood, gravel, sand, steel, concrete and paper products. The materials, apart from paper products, will be used during the construction period of the proposed project. However, their use will be limited. It is expected that the use of these materials during construction will result in negligible adverse effects on renewable resource supply as the construction materials will be procured from the licensed materials supplier. Fossil fuels, such as diesel fuel, gasoline and oil will be used during the construction and operation of the project and should have negligible adverse effects on renewable resources. Electricity will be used during construction to provide power to construction equipments and in operation for lighting of buildings and running utilities equipments. Electricity consumption will be kept at a minimum when possible by adopting electricity conservation measures. The project proponent will implement best management practices to conserve renewable resources. These may include, but are not limited to, Use of energy-efficient CFL lights; Lighting of only critical areas during non-working hours; Use of Solar Power Lighting and Solar heaters; Use of gear less lifts & variable frequency driven pump. Efficient scheduling of construction crews; Minimizing idling of construction equipments and vehicles. M/s. Salarpuria Properties Private Limited Page 62 of 105
