4 RAPID EIA STUDY FOR CONSTRUCTION OF RESIDENTIAL COMPLEX AT G.T. ROAD, MOUZA E.3 BASELINE STATUS Baseline Study was conducted in area with an angular distance of 10 km surrounding the proposed site. Baseline data for environmental attributes like ambient air, meteorology, water, water use, hydrology, land use, soil, geology, noise, socioeconomic, ecology and biodiversity etc. was collected. The study was conducted during the post-monsoon season from October to December, SITE SENSITIVITY The pattern of land use surrounding the project site is highly urbanized with some commercial units. Hence the land use pattern is mostly residential & commercial. Among sensitive structures in the 10 km. radius zone Hooghly River, some hospitals, industries and academic institutions exist. LAND USE The total plot area of proposed project is sqm. The proposed site is an open land. A single aquatic body exists here which will be retained and further developed. This was previously the area of Banga Lakshmi Cotton Mill, an industry. So in existing conditions, this place is not the habitat for local fauna. The project does not involve any displacement issues. TOPOGRAPHY Topography around the proposed project site is almost flat terrain with a gentle slope towards East. The debris generated during the construction phase will be used in leveling activities of various land-uses. SEISMOLOGY The project area is in Seismic Zone III and the construction of the buildings will follow all design guidelines prescribed for Zone III. SOIL QUALITY Soils are alkaline in nature with ph ranging from 7.49 to This is probably due to a certain excess of oxides and hydroxides of basic metals, particularly calcium and magnesium. Organic carbon in the soils is higher and varying between %. The available nitrogen, phosphorous and potassium contents are almost medium. METEOROLOGICAL CONDITIONS The monthly maximum and minimum temperatures, recorded on site during the study period varied between 11 0 C to 38 0 C. The maximum and minimum relative humidity recorded on-site during the study period varied between 98% - 15 %. J. B. ENVIRO S PVT. LTD. E-3

5 EXECUTIVE SUMMARY AMBIENT AIR QUALITY Six air quality monitoring stations were fixed at different directions within the Study area for EIA study. Monitoring of ambient air quality with reference to 12 parameters during October - December, 2017 revealed concentrations of all the measured parameters did not exceed the permissible limit of NAAQS. NOISE LEVEL A total of eight locations were selected for measurement of ambient noise levels, covering residential and commercial areas as well as silence zone. It is observed that the daytime and nighttime ambient noise levels in three categories are violated the relevant standards. The average day time noise level in the area varies between 60.9 to 78.9 db(a), while the nighttime noise level ranges between 54.7 to 73.4 db(a). WATER QUALITY 10 water samples (5 for ground water and surface water each) within the study area were collected for assessment of baseline water quality characteristics within the study area. The results exhibited that all the parameters are below permissible limit stipulated by CPHEEO except iron and turbidity in ground water. Arsenic, Chromium and leads are below detectable limit in all the sources. SOCIAL The proposed project site is an urban area located within the Serampore Municipality. The development of the present project will add pace in urbanization, leading to change in the existing social fabric of the area. This will have impact on the socioeconomic environment of the people of surrounding localities experiencing development in the study area. The study area taken for the purpose of socioeconomic study is 10 km radius. There are few blocks in the study area. In this section, an attempt has been made to understand the socio-economic status of the people residing in the study area. E.4 IMPACT ASSESSMENT There are both positive as well as adverse Environmental Impacts on different environmental attributes, which are identified through analysis of the baseline characteristics of the project area. The adverse impacts classified in mainly two categories, viz. Construction Stage and Operational Stage have been predicted with a focus to micro-climate, air flow, noise level, traffic load, soil quality, land-use, drainage pattern, water use and quality of both surface and groundwater. Feasible cost-effective mitigation measures have been adopted for sustainable environment. E.5 ANALYSIS OF ALTERNATIVES The proposed project has considered the different options for suitable site as well as most feasible technological opportunities. The proposed site is suitably selected based on the permission of Serampore Municipality, availability of building materials from the J. B. ENVIRO S PVT. LTD. E-4

ROAD, MOUZA nearby areas, water availability for the project, easy availability of electricity and solid waste disposal facility through the Municipal system, good road connectivity to the other regions of the State particularly easy access to different cities like Serampore, Rishra, Chinsurah etc. as well as Kolkata Metropolitan City. The alternative use of building materials for each component of the buildings like superstructure, finishing, passing area, road and surrounding areas will be followed as per the National Building Code of India, The proposed project will emphasize mainly on the use of recycled and environment friendly building materials, efficient use of water and water recycling, use of energy efficient and eco- friendly equipment, use of renewable energy, indoor air quality for human safety and comfort, etc. E.6 MONITORING Environmental Monitoring Programme is proposed to be carried out regularly to assess the quality of various environmental attributes to detect pollution level. The parameters to be monitored are air, water, noise and soil. E.7 RISK ASSESSMENT & DMP The project involves installation of various structures and machineries that meet the project requirement but may also pose serious threat to the workers and occupants in case of an accident. It is thus necessary to carry out hazard identification and risk assessment to formulate its Control Measures and Disaster Management Plan/Onsite Emergency Plan for the project. The overall objective of Disaster Management Plan (DMP) is to make use of the combined resources at the site and outside services to achieve the following To localize the emergency and if possible eliminate it; To minimize the effects of the accident on people and property; Effect the rescue and medical treatment of casualties; Safeguard other people; Evacuate people to safe areas; Informing and collaborating with statutory authorities; Initially contain and ultimately bring the incident under control; Preserve relevant records and equipment for the subsequent enquiry into the cause and circumstances of the emergency; Investigating and taking steps to prevent reoccurrence E.8 PROJECT BENEFITS The development of the proposed project will create a lot of benefits that may be directly or indirectly accrued to the society.

39 RAPID EIA STUDY FOR CONSTRUCTION OF RESIDENTIAL COMPLEX AT G.T. ROAD, MOUZA 3. DESCRIPTION OF 3.1 STUDY AREA AND PERIOD Environment Impact Assessment study was conducted within 10 km from the periphery of the proposed site. The map of the study area is given as Figure 3.1. Baseline data for environmental attributes like ambient air, meteorology, water, water use, hydrology, land use, soil, geology, noise, socio-economic, ecology and biodiversity etc. was collected. The study was conducted from October 17 to December 17. The status of ambient air quality was mainly focused near the adjacent areas of the project site. Further, a buffer area extending to 10 km radius from the site has also been studied, though with a lesser degree of detail in order to understand the land use and places of environmental sensitivity of the area. 3.2 METHODOLOGY ADOPTED The studies conducted by considering various environmental attributes were divided into primary and secondary studies. Primary attributes such as air environment, water, soil, noise, flora and fauna, and micro-meteorology were assessed by conducting field studies on-site monitoring and review of the past studies conducted and secondary attributes such as land-use studies, geology, physiological characteristics, and socioeconomic environment have been assessed by literature review of previous studies conducted by various Government publications etc. For collecting the baseline data (Primary and Secondary) during the study period, a temporary field office was established near the site. The following methodology was adopted for data collection Sampling of soil and water, monitoring of air quality and noise level and other field data collection were carried out by the team operating from the project site. A meteorological station was setup on the roof top of a house near project site. Wind speed, wind direction, dry and wet bulb temperature, relative humidity and general weather conditions were recorded throughout the study period. In order to assess the Ambient Air Quality (AAQ), samples of ambient air were collected by installation of Respirable Dust Sampler and Fine Particulate Sampler at different locations from the study area during study period and analyzed for primary air pollutants to work out the existing status of air quality. Ground water samples were collected during the study period from existing tube wells and surface water collected from water body and available local surface water body like River Hooghly, pond, lakes etc. J. B. ENVIRO S PVT. LTD. 3-1

40 CHAPTER-3 DESCRIPTION OF Soil samples were collected and analyzed for relevant physical and chemical characteristics in order to assess the impact of the proposed project on soil. The noise level measurements were made at various locations in one hour intervals of time with the help of sound level meter in the study area to establish the baseline noise levels in the study area. 3.3 LAND LAND USE PATTERN OF STUDY AREA The land use pattern indicates the manner in which different parts of land in the study area is being utilized. It is an important indicator to assess the environmental health and human activity and a degree of inter-play between these two indicators. The study area falls under Mouza Mahesh, Tehsil Serampore, Serampore Municipality, Hooghly District, West Bengal. Based on the guidelines the total study area has been classified under ten different land-use categories as follows Agriculture Airport Barren Land Large Industrial Complex Open Space River Built up Land Vegetation Water body Wetland The distribution of the different categories is presented in Figure 3.1.

43 RAPID EIA STUDY FOR CONSTRUCTION OF RESIDENTIAL COMPLEX AT G.T. ROAD, MOUZA LAND OWNERSHIP STATUS The proposed project does not involve any R&R issues. Banga Lakshmi Cotton (BLC) mill was located on this site long back. The status of the land was subsequently changed for residential cum commercial development. The land ownership documents are attached as Annex IV. 3.4 PHYSICAL TOPOGRAPHY Topography of the proposed project site is almost flat with a small high in the central part as is obvious from the contour map. A detail planimetric survey was carried out to understand the slope of the land. The survey was carried out with considering a fixed concrete slab within the project area as local benchmark located which was constructed at equal level to that of the adjoining road and height assigned to it was meter. The entire survey was carried out with respect to this benchmark. The spot heights of 524 points distributed randomly over adjoining vacant plots were collected through Total Station Theodolite survey and were imported into ArcGIS environment for generation of contours with.2 meter interval. The contour diagram describes the height of the plot with respect to adjoining areas as also the nearby roads, as below The debris generated from the construction phase will be used in leveling activities for various land-uses.

45 RAPID EIA STUDY FOR CONSTRUCTION OF RESIDENTIAL COMPLEX AT G.T. ROAD, MOUZA GEOLOGY This area is a part of the famous Gangetic plain. Due to the proximity of Hooghly tidal stretch, the macro-tidal environment has established a typical tide-dominated deltaic landscape with a very well developed lower deltaic plain on which the urbanized area is located. Apart from some small canals and nallahs, the dominant flowing water body is the Hooghly throughout its stretch in the study area is subject to semidiurnal tides. However, since the area is far away from the Bay of Bengal and more precisely the Sand Head (where the River Hooghly meets the Bay of Bengal), the tidal water is mostly pushed back freshwater with hardly any salt stress and beyond the CRZ limit as determined and delineated by the concerned authorities. It is very difficult to identify the different geomorphological units in Serampore and adjoining areas due to the urbanization and absence of exposure of surface materials in many areas. Part of the area also falls within Kolkata city. Satellite data do not reveal the detail geomorphic features apart from the pattern of settlements. As old settlements generally develop on the levee of a river-side, it is assumed that the Hoogly River levee extends from the Hooghly river bank to both sides namely the east and the west. The area around Serampore is covered by an alluvial cover deposited by the Hooghly River and its tributaries. These alluvial sediments are of Quaternary age. Lithological logs in the study area revealed that, the alluvial fill consists of a succession of clay, silt, fine to coarse sand, sand mixed with fine pebble. In the study area, fluvial processes have resulted in the formation of extensive Holocene flood plains with a dominance of coarser grained sediments, representing the overlapping of a number of sub- deltas. Avulsion of the major streams in the area, which are tributaries or distributaries of the River Ganges, within a time scale of 100 years, has resulted in a thick layer of tens of meters of Recent overbank silts and clays incised by channel sands. The coastal region of the south Bengal has a mixture of fine- grained sand and mud deposits with peat layers, which have resulted from eustatic influence. Deposition of the lowest parts of the Bengal Alluvium began at the onset of the Pleistocene glacial maximum, with sea level (i.e., regional base level) at least 100 m below present MSL. Thus, the rivers draining the plain during that time must have scoured through the earlier plains. Around 11,000 to 10,000 years before present (BP), deposition of lower delta mud over low-stand oxidized sand units started, suggesting sea level to about 45 m below present MSL. The present GBM delta began to proceed into the Bay of Bengal at this time. From 10,000 to 7,000 years BP, rapid marine transgression occurred resulting in the deposition of fine sediments. Since 7,000 years BP to the present, the general trend of the eustatic sea-level curve shows continuing sea-level rise, although with a decreased gradient. (Mukherjee et al, 2007). J. B.

46 CHAPTER-3 DESCRIPTION OF SEISMOLOGY The project area is in Seismic Zone III. Adequate design consideration to withstand the earthquake of maximum magnitude and intensity likely to occur in zone III will be considered during construction of the buildings. The IS code assigns zone factor of 0.16 for Zone III. Figure 3-3 Project Site in Seismic Map of India CLIMATOLOGY AND METEOROLOGY Onsite Micro-Meteorological Data The data have been collected on hourly basis for various meteorological parameters like ambient air temperature, relative humidity, wind speed and wind direction during October 17 to December 17. Data was processed to estimate daily average and summary of meteorological data are presented in Annex V. The range of these parameters and their distribution pattern are discussed below Temperature The monthly maximum and minimum temperatures, recorded on site during the study period varied between 16 and 36 0 C. Such wide variation may be attributed to diurnal effect, whereas variations among the days were not J. B. ENVIRO S PVT. LTD. 3-8

47 RAPID EIA STUDY FOR CONSTRUCTION OF RESIDENTIAL COMPLEX AT G.T. ROAD, MOUZA significant as reflected from standard deviation of both maximum and minimum temperatures of each day. Relative Humidity The maximum and minimum relative humidity recorded on-site during the study period varied between 98% & 15 % which demonstrated wide variation of relative humidity mainly due to diurnal effect. Wind-speed & direction Wind speed and direction were collected on hourly basis to draw wind rose. Details of Air data, as collected is enclosed as Annexure-VI. The wind rose diagram presented in Figure 3-3 revealed that prevalent wind direction was mainly from NE during the study period. Figure 3-4 Wind Rose Diagram for October 17 to December 17 J. B.

50 CHAPTER-3 DESCRIPTION OF 3.5 HYDROLOGY DRAINAGE PATTERN The area is drained by major Hugli River along its central part and by several canals like Bagjola Khal Kestopur Khal in the South-east, Icchapur Khal in the east, Noai Khal and Sonai khaal in the north-eastern side, Pachha Khal in east, and Saraswati Canal in the west which flows in the NNW-SSE direction. There are some unnamed khaals and canals also within the study area. Some of them starts from the side of the railway line and traverse a long distance through the study area. These khals and naalas cover a large area of the study area. At present all the khals and nalas have been mostly silted. They need proper desiltation as they are the main surface water sources inside the urbanized areas as well as within the agricultural land surrounding the urbanized areas. In some areas, these canal may even be used for inland water transport (Source Central Ground Water Board, Kolkata Municipal Corporation, LULC document, Serampore). The drainage pattern around the project site is well developed. KMDA has developed drainage all around the project site which is connected with the municipal drain. The storm water of the drainage will be discharged in these surface drains GROUND WATER HYDROLOGY Geological features control the occurrence of ground water in any area. The area under study is underlain by Quaternary sediments consisting of a succession of clay, silty clay, fine sand, medium to coarse sand and sand mixed occasional gravel WATER TABLE Depth to ground water level in use varies from to m below ground level (CGWB, pre-monsoon, 2006). Depth to ground water level in aquifer in use varies from to m below ground level (CGWB, post-monsoon, 2006) HYDRAULIC CHARACTERISTICS OF AQUIFERS Ability of an aquifer to transmit water depends upon its hydraulic conductivity, transmissivity and specific yield. Results of systematic pumping tests carried out in study area indicate that the major aquifers in the northern parts are characterized by greater potentiality than southern areas. J. B. ENVIRO S PVT.

79 RAPID EIA STUDY FOR CONSTRUCTION OF RESIDENTIAL COMPLEX AT G.T. ROAD, MOUZA 3.9 SOIL The study area is mainly developed land dominated by settlement followed by agricultural area for agricultural purposes. Besides the urban population being engaged in different kinds of engagements and professions, agriculture is also a major occupation of the people in the study area. Hence, it is essential to assess the soil quality of the study area. Although soil quality is not of much importance for areas covered under settlements and built up area, soil analysis was carried out to assess the agricultural and afforestation potential of the soil. For the purpose of greenery and landscape development, afforestation is required. Soil analysis helped in that purpose Assessment of Baseline Data on Soil Quality The area is a flat featureless plain having alluvial soils. It has already been discussed that the area falls within the Gangetic Basin and River Hooghly almost bisects the study area. To assess the baseline status of the soil quality in the study area, four soil samples were collected from different locations. The physical and chemical properties of the four soil samples collected around the area are given in Table 3.29 to Baseline Status The soils of the study area are formed through alluvial deposits and overlain by more recent back swamp deposition of the Hooghly River. The soils are light to grey coloured and poor in calcareous materials. In general three types of soils have been recognized in Hoogly district, viz. i. residual types derived from weathering of granites, gneisses andschist, ii. Lateritic soil and iii. Sandy Clay loam to clay. However, it is not expected to get all these three types of soil within the study area. Soils in the area are mostly Sandy clay loam or clay in texture and contain large percentage of Sand and clay and hence possess moderate water holding capacity. Only in areas close to rivers, soils are sandy clay. Alluvial soils are often very fertile. Bulk density of soil samples varies between 1.27 to 1.45 gm/cm 3. The soils of all the sites are J. B. ENVIRO S PVT. LTD. 3-41

80 CHAPTER-3 DESCRIPTION OF moderately porous (porosities ranging between 39.1 to 42.7%). ph of soil samples ranged between 6.5 to 6.8, indicating soils are slightly acidic in nature. The availability of nitrogen is of prime importance to grow plants since they are dependent on adequate supply of nitrates and ammonia. Total kjeldahl nitrogen available for different soil sample ranged between 0.18 to 0.51%. Available potassium concentration ranged between 0.09 to 0.15%. Phosphorus has several essential functions in plant growth. The available phosphorus concentration in the study area has varied from 0.09 to 0.17%. The soil quality indicates that the area is good for afforestation, but nutrition supplement will be required for good landscape development. J. B. ENVIRO S PVT. LTD. 3-42

85 RAPID EIA STUDY FOR CONSTRUCTION OF RESIDENTIAL COMPLEX AT G.T. ROAD, MOUZA 3.10 BIOLOGICAL Natural flora and fauna are important features of environment. They are organized into communities with mutual dependencies among their member families and show various responses and sensitivities to outside influences. A biological system comprises of both plant and animal communities, which interact not only among themselves but also with the abiotic components, viz. physical and chemical characteristics of the environment. Therefore, nature of developments and baseline characteristics of terrestrial and aquatic flora and fauna around the site of proposed activities is required to be assessed. Plants and animals are more susceptible to environmental stress. A change in the composition of biotic communities is reflected by a change in the distribution pattern, frequency, density and abundance of natural species of flora and fauna existing in the ecosystem. These changes over a span of time can be quantified related to the existing environmental factors. Assessment of area surrounding the site for plant and animal species was carried out by field survey and collecting the available information from authentic sources. There is no threat to the Biodiversity. Altogether 21 trees are present in the project area. These trees will not be felled and will be retained during construction. The operation stage of the proposed project will not pose any significant impact to the biodiversity of the area. Moreover plantation program will give shelter to the avifauna. The proposed complex will have landscape garden and plantation along the boundary, roadside and inside the hard surface area. This plantation programme will create a better landscape quality as well as a barrier for dust and noise FLORAL BIODIVERSITY The floral species recorded in the study area is attached as Annex VII FAUNAL PROFILE The checklist for faunal species recorded in the study area is attached as Annex VIII SOCIAL DEMOGRAPHIC CHARACTERISTICS Development activity normally have an impact on the socio-economic condition of the people in the region and thus on the quality of life.

IMPACT ASSESSMENT & MITIGATION MEASURES 4.1 INTRODUCTION Prediction of environmental impacts is an important part of impact assessment as it provides quantitative as well as qualitative environmental consequences from the proposed project well in advance. Several techniques and methodologies are available for predicting impact from any proposed developmental projects on the surrounding physio-chemical, ecological and socio-economic components of the environment. This chapter presents identification and appraisal of various likely impacts due to the proposed township project. 4.2 IMPACT DURING PRE-CONSTRUCTION PHASE The impact in pre-construction is stage is associated with social profile of the area. The flow of men, money and material will affect the socio-economic status of the people in the area. Growth of shops, hotels and other allied services will open up avenues for employment. 4.3 IMPACT ON AIR QUALITY IMPACT DURING CONSTRUCTION PHASE The main air pollutant affecting the air quality would be the particulate matter during the construction phase and air pollutants from running of vehicles. During construction phase, it will be ensured that vehicles must have valid Pollution under Control (PUC) certificate for transportation of construction materials. Vehicle carrying construction material will ply during off peak hours and stay inside the project area and loading & unloading operation will be done during next day time (9 AM to 6 PM). Adequate security personnel will be posted at the entry and exit points of the complex to supervise traffic management in and around the complex. Some quantities of dust could be generated during excavation, backfilling and other allied operations. Water will be sprinkled to reduce the generation of dust as well as to maintain soils in a visible damp or crusted condition for temporary stabilization. Moreover the construction area would be enclosed to a suitable height to resist the fugitive dust to travel outside the construction area. However, wind speeds being low, windblown dust are not expected to have any tangible effects. J.B. ENVIRO S PVT. LTD. 4-1

89 CHAPTER-3 BASELINE IMPACT DURING OPERATION PHASE The project will be a residential housing complex. During power failure DG will be source for air pollution. The emission from DG sets of 9 nos., each having 630 KVA capacity will be discharged through stacks of 5.0 meter for each 630 KVA DG set above the roof of the DG buildings. Fuel (diesel) required for the DG sets will be around 907 liters/hr. (as per CPCB norms), which will be low sulphur diesel. The emission from DG sets will be maintained as per the norms of CPCB given below PM < 0.3 G/kW-hr, CO < 3.5 G/kW-hr, HC < 1.3 G/kW-hr& NO2< 9.2 G/kW-hr During operation stage the project will not generate any pollutants - which will pollute the air quality of the area. There are no significant impacts on air quality during operation phase. 4.4 IMPACT ON NOISE LEVEL IMPACT DURING CONSTRUCTION PHASE During the construction phase, machineries like rigs for piling, mixture machines, etc. may be used, which would emit sounds at the vicinity of the machines. DMC piles will be used because DMC piling operation produces less sound IMPACT DURING OPERATION PHASE The project is a housing complex, so the project is not expected to generate any high noise levels as is felt from an operating industry or plant. However, sometimes DG sets may generate some noise, which may not be disturbing. All possible precautions will be taken to control such noise levels. The ambient noise levels are thus expected to remain at present day levels. 4.5 IMPACT ON TRAFFIC LOAD IMPACT DURING CONSTRUCTION PHASE During the construction phase traffic load would be increased. It would be ensured that vehicles must have valid Pollution under Control (PUC) certificate for transportation of construction materials. Vehicle carrying construction material will ply during off peak hours and stay inside the project area and loading & unloading operation will be done during next day time (9 AM to 6 PM). Adequate security personnel will be posted at the entry and exit points of the complex to supervise traffic management in and around the complex. J. B. ENVIRO S PVT. LTD. 4-2

90 RAPID EIA STUDY FOR CONSTRUCTION OF RESIDENTIAL COMPLEX AT G.T. ROAD, MOUZA MAHESH, SERAMPORE, WEST BENGAL A detail Traffic Impact Analysis (TIA) has already been carried out by M/s GMD Consultants of Mumbai which is a part of this report. The report has pointed out several avenues to decrease the traffic load, which will be followed during operational stage IMPACT DURING OPERATION PHASE The project is a housing complex. Adequate no of car parking provision has been kept as per Municipal bye laws. Adequate security personnel will be posted at the entry and exit points of the complex to supervise traffic management in and around the complex. 4.6 IMPACT ON SOIL QUALITY IMPACT DURING CONSTRUCTION PHASE The proposed project would be constructed on fallow land. Site preparation activities (like site clearing and leveling, excavation, earth movement) and construction activities may result into loss of fertile topsoil of the construction area. However, efforts will be made to preserve top soil and reuse the same for greenbelt development IMPACT DURING OPERATION PHASE The project is expected to generate daily of about kg/day of solid waste. The principal fraction of this waste is garbage. Solid waste will be segregated at source for biodegradable, non-biodegradable and inert material and stored in a properly lined impervious designated place as per Construction Manual within the project site Mechanical composter will be used for organic part to convert it in to manure (vendor interaction is in process). Total amount of Organic waste for the project will be kg/day. Altogether 2037 Kg/day of inorganic-recyclables will be sold to vendor (vendor development is in process). In-organic inert material of kg/day say 4900 kg/day will be ultimately disposed off by Serampore Municipality in regular manner as per MSW (M&H) Rules Discarded lube oil will be stored in HDPE container as per Hazardous Waste (M&H) Rules 1989 and its subsequent amendments and finally sold to the authorized vendor of MoEF. About 400 sqm of area will be earmarked in the project site for storage of solid waste and composting. No contaminated or toxic wastes are expected to be generated within the project. No leachate is expected to be generated from this waste, which may pollute the adjacent soils of the area. As such, no impact on soils due to operation of the project would be felt. J.B. ENVIRO S PVT. LTD. 4-3

91 CHAPTER-3 BASELINE 4.7 IMPACT ON LAND-USE IMPACT DURING CONSTRUCTION PHASE The land is fallow in nature but designated as residential use as per Happy Niketan Pvt. Ltd. The land, which has already been acquired and under possession of the Project Proponent, will be developed for construction of housing complex. The land use pattern will remain unaltered. Thus, no impact would be felt during construction phase IMPACT DURING OPERATION PHASE During construction phase, the modified land use pattern would gradually stabilize during the operation stage. The housing complex would substantially alter the present landscape. In order to create a proper landscape and visual comfort, the project authorities would adopt open space, green area etc., which will beautify the proposed project. 4.8 IMPACT ON DRAINAGE PATTERN The area of the project site is a land under massive urbanization and thus is a completely developed land comprising of mostly residential and commercial land use. By applying rational formula the peak rate of storm runoff considering 12 mm/hr rainfall during operation stage of the residential complex is given below. The surrounding area is mainly composed of residential area. By applying rational formula the peak rate of storm runoffs considering 12 mm/hr rainfall have been calculated and are given hereunder. Total land area of the proposed project is sqm, i.e. Total land area is ha. By applying rational method the peak rate of run-off = 10 x 0.60 x 12 x cum/hr = cum/hr= cum/sec. Non scouring and non-silting velocity is 1m/sec. The required diameter of pipe is mm say 445 mm. The storm drains of the complexes will be collecting and conveying the rainwater into the adjacent municipal drain. The internal drainage system will be designed considering the invert level of the outfall to avoid any flooding or water logging in the site. Construction site runoff will be routed through sedimentation tank/catch pit before final disposal to the Municipal drain. Drain (outfall) in-front of the project site will be used to avoid any flooding or water logging in the project site. The project will not alter the natural drainage system of the area. J. B. ENVIRO S PVT. LTD. 4-4

92 RAPID EIA STUDY FOR CONSTRUCTION OF RESIDENTIAL COMPLEX AT G.T. ROAD, MOUZA MAHESH, SERAMPORE, WEST BENGAL IMPACT DURING CONSTRUCTION PHASE Drains of required sizes will be created on the periphery of the land plot before initiation of construction for carring the storm waters during operational phase. Peripheral drains would be designed in such a manner that it will not only carries the storm runoff from the proposed project but also carry the storm water from neighborhood area leading to municipal drain. The storm run-off from the site will be routed through catch pit to this peripheral drain IMPACT DURING OPERATION PHASE During construction period the construction of peripheral drains would be completed. During operation phase due to increase of hard area, the surface run-off from the plot will be increased. The drainage system would be designed considering 2-years storm frequency to minimize the occurrence of flooding in the vicinity of the project area. 4.9 IMPACT ON WATER USE & QUALITY IMPACT ON SURFACE WATER QUALITY DURING CONSTRUCTION PHASE Required water will be supplied by Serampore Municipality both at construction stage as also in Operational Phase. However, the project proponent will explore the possibility to withdraw surface water from the River Hooghly with due permission from Authority. Since there will be no water exchange with the River Hooghly, there will be practically no impact on River Hooghly due to construction of this project. The project authority would make adequate arrangements for proper wastewater disposal from the construction site, so that water does not form stagnant pools, which may turn into a breeding ground of mosquitoes IMPACT ON SURFACE WATER QUALITY DURING OPERATION PHASE INCLUDING RIVER HOOGHLY Total fresh water demand of the project during operational phase would be about 1554 KLD which will be supplied by Serampore Municipality. The total volume of wastewater generated from the project will be 1854 KLD. A substantial quantity 692 KLD of t r e a t e d wastewater (434 KLD for flushing, 139 KLD for gardening and 119 KLD for Car washing) will be recycled to the system to reduce fresh water consumption. Only 1162 KLD of treated wastewater will be discharged in Serampore J.B. ENVIRO S PVT. LTD. 4-5

93 CHAPTER-3 BASELINE Municipal drain in front of the project site leading to disposal. The treated wastewater characteristics will be (ph , TSS - <10 mg/l, BOD - <5 mg/l, COD - < 15 mg/l, Oil & Grease - < 1 mg/l, Fecal Coliform - Nil) such that it would be discharged in the surface water bodies maintaining the stringent norms as per EPA As such no adverse impact would be felt on receiving water bodies. The project proponent will explore the possibility to withdraw surface water from the River Hooghly with due permission from Authority. There will be recycling of treated waste water to the maximum extent possible and the excess treated waste water will be discharged into the municipal drain near the project. Since there will be no water exchange with the River Hooghly, there will be practically no impact on River Hooghly during operational phase of this project IMPACT ON GROUND WATER DURING CONSTRUCTION PHASE The entire requirement of water, during both construction stage as also during operational stage will be made from Surface Water only. During Construction phase, water will be supplied by Serampore Municipal Supply. During Operational phase, water will be taken from River Hooghly and will be supplied after proper treatment. There will be no abstraction of groundwater. Therefore any impact on ground water table and ground water quality is ruled out IMPACT ON GROUND WATER DURING OPERATION PHASE The impact on ground water by this type of project is primarily due to any leachate from solid waste from the project. The present project would generate MSW of kg/day and will be segregated at source for biodegradable, non-biodegradable and inert material and stored in a properly lined impervious designated place as per Construction Manual within the project site. The Organic part of it will be managed inhouse by installing mechanical composter (400 sqm is earmarked for onsite MSW management), inorganic recyclables will be sold to vendors (vendor development in process) The Inorganic Inert material of around kg/day, say 4900 kg/day would be collected, transported, disposed and treated by Serampore Municipality as per MSW (M&H) Rules, 2016 in regular interval. The project would not create any leachate from its solid waste, and as such no contamination of ground water is expected. J. B. ENVIRO S PVT. LTD. 4-6

ANALYSIS OF ALTERNATIVES 5.1 ALTERNATIVE SITE The project comprises of development of residential and commercial facilities and by virtue of its nature will not contribute significant impact on the environment. Hence due diligence in terms of site selection is not required for the project. Thus, exploration and analysis of alternatives in the same line is not required for the project. 5.2 BUILDING MATERIALS Analysis of alternative building materials in township projects can help to identify sources which can lead to energy conservation to a great extent as well as use of recyclable materials thereby taking a step forward towards sustainability. The conventional materials and methods of construction are energy intensive in nature. Scope of this section covers the selection guidelines for alternate materials and technologies at various stages of building construction. Alternative options in building materials are summarized in Table 5-1. Sl. No. Table 5-1 For use in Conventional Materials Alternate Materials Wall Clay bricks with cement Earth blocks Earth blocks mortar stabilized with 5% 15% of cement are good choice for low cost, low-rise construction in hothumid climates. Brick and block products with waste and recycled contents such as fly ash (waste from coal burning plants), blast furnace slag, sewage sludge, waste wood fibre, rice husk ash, etc. Concrete blocks using lime or waste wood fiber provide reduction of waste and saves energy. Fly ash can be used to replace about 15% to 35% of the total cementitious material. The slag content can be used to replace the same between 20% J. B. ENVIRO S PVT. LTD. 5-1

104 RAPID EIA STUDY FOR CONSTRUCTION OF RESIDENTIAL COMPLEX AT G.T. ROAD, MOUZA 7. RISK ASSESSMENT & DMP 7.1 INTRODUCTION Any constructional project involves lot of activities like installation of various types of structures and machineries. These activities include lifting and transportation of building materials at different levels, digging pits, operation of concrete mixer, working near electrical circuit, which is required during construction of such housing project. Hence such work puts workers at risk of burial, engulfment or falling from a height, risk of electrocution where the risk is particularly aggravated by the nature of the work or processes used or by the environment at the place of work or site. On completion of project, the infrastructure created includes provision of lifts, DG set as power backup, laying of internal as well as external electrical cables, provision of pipeline for LPG uses (specially in kitchens), construction of internal roads etc., which may also pose risk of accident to the occupants. However, it is not always possible to totally eliminate such eventualities and random failures of equipment due to human errors or natural calamities like earthquake. It is thus necessary to carry out hazard identification and risk assessment for risk monitoring and to formulate its Control Measures like Risk response planning i.e. Disaster Management Plan/Onsite Emergency Plan for the project. An essential part of major hazard control is therefore, to be concerned with mitigating the effects of such emergency situation and restoration of normalcy at the earliest by following Disaster Management Plan (DMP) for different type of Emergencies like Earthquake, LPG leakage, Fire in the building etc. 7.2 SAFETY CODE FOR BUILDING & FIRE FIGHTING SYSTEM The Fire fighting network followed by Emergency Response mock drills are essential part of Risk Control Measures. The project site falls under residential occupancies. Following provisions are required to be made according to National Building Code The fire fighting system is to be designed considering the following codes, manual and guidelines; National Building Code of India (NBC); Latest relevant NFPA codes, USA, in particular NFPA 13, 14, 20 & 22; IRI guidelines; As per requirement of fire officer/local fire approving authorities; and J. B. ENVIRO S PVT. LTD. 7-1

105 CHAPTER-7 RISK ASSESSMENT & DMP As per Indian Standard Code for Fire Protection (IS Codes) Following items are envisaged for firefighting Fire-Water Connections; Firewater inlet and outlet connections shall be provided to the water storage tanks; External main fire ring, hydrants shall be provided. This external fire ring shall be separated from the Sprinkler Main Systems; All flow switches, test valves, drain pipes etc. shall be provided as per NFPA guidelines on the sprinkler system; All pump installation and arrangements shall be in accordance with IRI guidelines and NFPA-20; All pumps and accessories and electrical controllers shall be as per UL/FM lists, tested, approved and certified; and By-pass arrangements shall be provided with NRV and gate valve and bulk flow meter on the discharge header of each pump to check the duties of pumps. Storage tanks are provided in the basement for the supply of water for the firefighting facility. The fire extinguishers provided should be in conformance with Ozone Depleting Substances (Regulation and Control) Rules 2000 and subsequent amendments thereof. 7.3 DISASTER MANAGEMENT PLAN The overall objective of DMP is to make use of the combined resources at the site and outside services to achieve the following To localize the emergency and if possible eliminate it; To minimize the effects of the accident on people and property; Effect the rescue and medical treatment of casualties; Safeguard other people; Evacuate people to safe areas; Informing and collaborating with statutory authorities; Initially contain and ultimately bring the incident under control; Preserve relevant records and equipment for the subsequent enquiry into the cause and circumstances of the emergency; Investigating and taking steps to prevent reoccurrence The DMP is, therefore, related to identification of sources from which hazards can arise (based on Hazard Identification) and to minimize credible loss scenario that can J. B. ENVIRO S PVT. LTD. 7-2

106 RAPID EIA STUDY FOR CONSTRUCTION OF RESIDENTIAL COMPLEX AT G.T. ROAD, MOUZA take place in the concerned area. The DMP takes into account the maximum credible loss scenario and actions that can successfully mitigate the effects of losses. Hence emergency plan need to be well planned, so that with less effort and resources, emergencies may be controlled and terminated, in minimum time, to reduce damages to life and properties. The Disaster Management Plan is designed to Anticipate the types of disasters that are most likely to occur. Identify the possible effects of any disaster that may occur. Identify the preventative and mitigating strategies to deal with any possible disaster. Involve all role players in a coordinated manner to respond to the challenges posed in disaster situations. Procure essential goods and services for disaster management. Identify the weaknesses in respect of capacity and skills to deal effectively with disastrous situations. Provide essential training and skills to handle such disaster and to promote awareness and preparedness in respect of the occurrence of disasters. Plan in advance the relief and rescue operations that may be required or to be exercised in disaster situations. The hazard identified for the project include hazards pertaining to fires in buildings, commercial areas and fire in diesel storage areas, earthquake and LPG leakage and DMP pertaining to these as described in the following section. 7.4 RESPONSE IN CASE OF EARTHQUAKE RESPONSE PROCEDURES FOR OCCUPANTS IF INDOORS Take cover under a piece of heavy furniture or against an inside wall and hold on. Stay inside The most dangerous thing to do during the shaking of an earthquake is to try to leave the building because objects can fall on you IF OUTDOORS Move into the open, away from buildings, streetlights, and utility wires. Once in the open, stay there until the shaking stops. J. B. ENVIRO S PVT. LTD. 7-3

MANAGEMENT PLAN 9.1 INTRODUCTION The Environmental Management Plan (EMP) is the synthesis of all proposed mitigation and monitoring actions, set to a time frame with specific responsibility assigned and follow-up actions defined. EMP is a plan of actions for avoidance, mitigation and management of the negative impacts of the project. Sound Environment Management Plan (EMP) will be implemented, which will make environment protection an essential requirement. 9.2 MANAGEMENT CELL A separate environment management cell comprising of a team of experienced and qualified personnel reporting to a very senior level executive preferably an environmental engineer is proposed who will be assisted by well trained staffs comprising of environmental and safety specialists. Staffs will be trained for environment control measures like air, water quality monitoring, solid waste management, noise abatement etc. Staffs would also be trained to operate STP and other pollution control equipment at optimum efficiency. Environmental Management cell will also monitor and analyze the various environmental parameters as per regulatory requirement. The responsibilities for undertaking specific activities at design, construction and operation stages are listed in Table 9-1. Table 9-1 Responsibilities of Different Organizations Project Stage Responsible Organization Responsibilities Participatory design Project Consultants Minimize non-avoidable losses by specifying mitigation and enhancement measures for engineering design, bid & contract documents, nonstructure program plans & periodic implementation plans Project Management Review and approve environmental mitigation measures Construction Phase Contractors Project management Project Engineers Implement required environmental measures Supervise contractors & service providers for implementation of EMP and enforce contractual requirements Monitor and report environmental indicators J.

The landuse planning within the proposed site has been planned keeping in mind all the spheres that can be impacted by the project activities. The layout plan is shown in Figure 2.2 (refer Chapter 2) and the area statement is given in Table 2.1. (refer Chapter 2). Proposed ground coverage is % which leaves adequate open space in the site. This has got a two-fold benefit. Firstly, substantial green cover that lowers albedo (reflectivity) compared to that of paved surface resulting in reduction of glare and temperature stratification. Secondly, absorption of rainwater through the green cover recharges the ground water level and also reduces the load on the storm water channels due to lesser surface run-off. Additionally, green cover reduces heat carried into adjoining building due to its lower reflectivity and maintains lower air temperature adjacent to the building by promoting evaporative cooling SOIL QUALITY CONSTRUCTION PHASE The earth stockpiles will be provided with gentle slopes to prevent soil erosion. Drains and detention basins will be provided to collect the surface runoff. Regular watering and maintenance will be undertaken to ensure green cover restoration of the area. To avoid soil compaction along the transportation routes and parking spaces, only identified haulage roads will be used for transportation. During the transportation of construction materials, vehicle parking shall not be done on the sides of the road over the green areas. At the maintenance and fueling station for vehicles, contamination of soil from oil and lubricants will be avoided through good practices such as Storage of petroleum products on impervious floor to avoid soil contamination Spillages will be wiped with cloth Used lubricants will be collected and recycled J.

115 RAPID EIA STUDY FOR CONSTRUCTION OF RESIDENTIAL COMPLEX AT G.T. ROAD, MOUZA Fuel storage and refueling will be located away from storm water drains Construction vehicles and equipments should be properly maintained Constructional wastes will be collected and stored at designated places and will be used in constructional activities and landscaping to the extent possible OPERATION PHASE Regular maintenance of the planted trees will be carried out to achieve the green cover as planned. Good housekeeping practices should be followed. Garbage will not be dumped in the open areas but stored and disposed off only as per proposed plan AIR QUALITY CONSTRUCTION PHASE Fugitive Dust Emission All dust producing construction materials will be transported in covered truck only. Water will be sprayed in the cement and earth mixing sites. In high dust areas, workers should be provided and encouraged to use nose masks. The concrete mixing plants shall be located at appropriate distance from the residential areas. Gaseous Emission Periodic emissions check for equipments and machineries shall be carried out. Regular maintenance, servicing of the vehicles and periodic emission check for equipment and machinery shall be carried out. Species selected for greenbelt development will be planted during construction phase so that they attain a certain height by the time of commencement of operation of the project OPERATIONAL PHASE There will be a dense plantation along the boundary of the proposed site. To further minimize vehicular pollution, good road conditions shall be maintained. The DG sets would be provided with stacks of adequate height as per CPCB guideline. Since the project will consist of a residential housing complex, during power failure, DG will be used which will be a source for air pollution. Use of low sulphur content ultra pure diesel reduces SO 2, NOx and PM emissions from the DG sets. The emission from DG sets will be discharged through stacks of 5.0 meter for each 630 KVA DG set above the roof of the buildings. Fuel (diesel) required for DG sets will be around 907 liters/hr. The emission from DG sets will be maintained as per the norms of CPCB given below PM < 0.3 G/kw-hr CO < 3.5 G/kw-hr HC < 1.3 G/kw-hr J. B. ENVIRO S PVT. LTD. 9-3

ROAD, MOUZA NO 2 < 9.2 G/kw-hr WATER QUALITY CONSTRUCTION PHASE The maximum expected sewage generation during construction phase is 176 KLD. The construction camps will be provided with septic tanks along with Soak Pits for collection and treatment of sewage. No sewage will be discharged into the surface water bodies. Runoff from the construction site shall not be allowed to stand (water logging) or enter into the roadside or nearby drain. Adequate measures shall be taken to collect such run off and either shall be reused (if possible) or disposed at the designated construction waste disposal location OPERATIONAL PHASE Sewage Treatment Plant All wastewaters from the project site will be connected to and will be treated in the well designed Sewage Treatment Plants and the treated wastewater will conform to applicable standards. STP will be based on the principle of MBBR followed by tertiary treatment (pressure sand filter, activated carbon filter and UV radiation) to recover the treated water (recycled water) of suitable quality for use for flushing, landscaping and car washing. Treatment Process The sewage is first passed through a bar screen chamber to trap any extraneous / floating matter present in wastewater followed by an oil & grease chamber to remove the oil and grease.. The sewage is then collected in a receiving sump where the variations in flow and characteristics are dampened to maintain constant flow to the Fluidized Aerobic Bio Reactors. Proper mixing of sewage water is done by means of coarse air bubble diffusion. The equalized sewage is then pumped to the Fluidized Aerobic Bio Reactors (FAB) where BOD/COD reduction is achieved by virtue of aerobic microbial activities. Microbial population is maintained to ensure functionality of FAB in removing the organic load. The FAB reactors run in series. The oxygen required is supplied through fine air bubble diffusers. The excess bio-solids formed in the biological process are separated in the Tube Settler Tank. The clear supernatant after disinfections is sent to the tertiary J. B. ENVIRO S PVT. LTD. 9-4

However, rainwater harvesting for the project will be carried out based on the Freshwater demand per day and Built up area as per the latest guidelines of Ministry of Environment & Forests and CC. The basic principle that has been followed in these propositions is that we are proposing to make surface water storage to meet up one 1 (one) day freshwater demand for each phase and subsurface recharge through 1 no. 150 mm diameter tube well per 5,000 Sqm built up area. From the local survey/the agencies working for doing bore wells, it is observed that there are prominent sand layers (aquifer) in the 80.0 to meter zone. This is the second aquifer which is getting exploited maximum for groundwater extraction, although in this project no groundwater extraction will be carried out. Hence we are proposing to install the strainers in between 88 to 100 meter zone. The quantity of Recharge, Q can be calculated through the following formula for Aquifer Q = [2(22/7) * T *(H-h)] /[2.3 log 10(R/r)] Where, J. B. ENVIRO S PVT. LTD. 9-7

Total Built Up area of this sector is 3,89, Sqm. We are proposing 8 no. storage tank of 200 cum capacity for rooftop rainwater storage. Thus, the surface storage of Rainwater will be 1600 Cum. Total number of 150 mm diameter tubewell to be augmented = 3,89, / 5,000 = say 78 Hence we are proposing to augment 78 (Seventy Eight) number of recharge wells. Total quantum of potential recharge from these 78 recharge well per annum = Cum X 78 = 3,30,936.84Cum say 3,31,000 Cum All rooftop rain water will be diverted to 8 nos. of rainwater storage tanks of 200 cum capacity and overflow of the tank will be diverted to recharge structures and overflow of the recharge structures will be diverted to storm water drain within the campus.

123 RAPID EIA STUDY FOR CONSTRUCTION OF RESIDENTIAL COMPLEX AT G.T. ROAD, MOUZA run-off will also be passed through Oil and Sedimentation Chamber before discharging. During rains to overcome any eventuality of the overflow, pipes will be laid connecting rain water harvesting storage structures to the storm water drains of municipal authority. This arrangement will ensure that most of the run-off water is disposed off with a runoff efficiency of 30-40% in case of the green covers and 90% in case of cemented areas so as to avoid flooding within the complex. Water Use Reduction and Water Conservation Measures Water usage for applications such as flushing, bathing and washing is as high as 90% of water demand in any building. However, measures can be adopted to reduce this demand through use of water efficient practices and devices (efficient plumbing fixtures). The conventional fixtures used in toilets use water at the rate of litres per flush. Use of more efficient water saving toilets having low rate flushing system can save of at least 50% of water. In the present case, the arrangements will be made so that water at the rate of 3 6 liters per flush will be used in the toilets. Dual plumbing system will be provided for this project to reuse the treated wastewater in flushing system. In the landscape areas, treated wastewater will be used to reduce the fresh water consumption. Apart from that, treated wastewater will also be used for car washing. As the car washing in a house is not similar to that of in servicing centre, so much oil or grease may not be discharged from the car washing NOISE QUALITY CONSTRUCTION PHASE Major construction activities will be carried out in the daytime only up to the extent possible. Noise levels will also be considered during selection and procurement of construction equipment. Wherever possible, acoustic enclosure will be provided for noise generating equipments. Regular maintenance of vehicles and equipments will also be helpful to keep the noise level within standards OPERATIONAL PHASE The major sources of noise during the operational phase are DG sets, compressor and traffic. The DG sets will be procured with acoustic enclosure and the other compressors and pumps will also be acoustically covered. The traffic during operation has been so planned such that there is least idling and bottle necks. No road less than 6.0 m width is proposed resulting in free flow of traffic. Plants (Greenbelt) will be used as a natural way to reduce outdoor noise levels. Scattering and ground attenuation are the principal factors in sound attenuation by vegetation. J. B. ENVIRO S PVT.

The hazardous waste are mainly of centering oil, grease, water proofing compounds, paints, wood dust from treated wood, discarded lube oil etc.. Special care will be taken to prevent spillage so that the hazardous waste will not be mixed with non-hazardous waste. Proper ventilation arrangement for painting work will be done to minimize exposure of workers. Discarded lube oil will be stored in HDPE container as per Hazardous Waste (M&H) Rules 1989 and its subsequent amendments and finally sold to the authorized vendor of MoEF. Garbage will be segregated at source for biodegradable, in-organic recyclables and inorganic inert material during construction phase kg per person for 3150 labours OPERATION PHASE Garbage will be segregated at source for biodegradable, in-organic recyclables and inorganic inert material during operational phase (10184 kg/day). As per construction manual and Mechanical composter will be used for organic part to convert it into manure, inorganic-recyclables will be sold to vendor (vendor development is in process) and in-organic inert material kg/day say 4900 kg/day will be disposed off by Serampore Municipality as per MSW (M&H) Rules Area of 400 sqm will be earmarked in the project site for storage of solid waste and composting (Refer Annexure XI).
