Monitoring of Additional Parameters:
The monitoring for additional parameters in ambient air namely Ozone, Lead, Ammonia, Arsenic, Benzene, Nickel &Benzo(a)pyrene was conducted within the project premises (A1 location). It can be stated that concentration of Benzene, Benzo(a) pyrene & Ammonia was found to be below the detection limit. The values of Ground level ozone were estimated to be within the range of 21 to 30.6 µg/m3. The average concentration was computed to be 25.5 µg/m 3. The presence of heavy metals such as lead, arsenic and nickel were estimated to be below the detectable limits and thus their presence can be said to be negligible. As mentioned earlier the concentration of VOCs was also monitored at the project site. The results revealed that the concentration was found to be below the detection limit as presently. The analysis of additional parameters monitored for ambient air quality at the location A1 reveals that the values did not exceed the limits prescribed by CPCB, during the sampling period.

Phosphate mg/lit 8.6/(GW-7) 27.6 (GW-4) Bicarbonate mg/lit 78/(GW-7) 190(GW-6) Chromium mg/lit <0.05 at all locations
Interpretation: The values obtained are compared with the IS: 10500:2012.
The concentration of heavy metals like arsenic, zinc, chromium, lead, mercury, nickel & cadmium were below detection limit. Iron was not detected in any of the ground water samples. The hardness of all the ground water samples was found to be ranging between 104-177 mg/lit. The value of hardness was within the acceptable limit at all the locations. It can be observed that the values for total dissolved solids in all the sampling locations were estimated to be under the acceptable standards for drinking water. The concentration of total dissolved solids ranged between 258-390 mg/lit. The maximum concentration was observed at location GW 3 whereas the minimum concentration was observed at GW4. It should be noted that the microbiological analysis of allthe samples indicate that e-coli was absent in all the ground water samples. The presence of total coliforms except for GW1 ,GW6& GW8 were in the range from 15-26 Org/100 ml indicate that the anthropogenic activity in the surrounding area can be a possible source of contamination. It should be noted that the concentration of the coliforms were higher in the dugwell compared to the concentrations observed in the borewell samples. The fluoride concentrations are ranging between 0.20 - 0.434 mg/l. The presence of the fluoride in all the water samples is mostly due to geogenic in nature. The nitrates concentrations were ranging between 2.0 - 9.3 mg/l well below the acceptable limits of drinking water. The probable sources of nitrates in the ground water could be the use of fertilizers in the nearby agricultural activity. The COD and BOD values of all the ground water samples were found to be below the detection limit. Thus based on the above results it can be stated that the water from the said samples can be considered fit for consumption and potable purpose with basic primary treatment. The water can be used for domestic utilization and gardening without any treatment.

CHAPTER 3: DESCRIPTION OF THE ENVIRONMENT
3.1 Introduction An overview of the process of EIA is depicted in the Fig. 3.1. The methodology of the consultant organization to carry out the EIA study is presented in Fig. 3.2. Out of the above mentioned aspects the present section focuses on monitoring of present environmental conditions such as air quality, water quality, soil and noise pollution levels. The monitoring duration for the study was considered for three months as per guidelines. The season in which the data was collected for the study area was winter.Including the collection of onsite meteorological data during the study period.The study also encompasses the ecological biodiversity of the 10 Km study area. Other aspects which are indirectly related to the environment such as traffic conditions, hydro- geology, socio-economical status of the population and land use and land cover details are also discussed in the present study. The Standard Operating Procedures (SOPs) for all the functional areas applicable in this study are followed from SEE-METH-EIA-01 to SEE-METH-EIA-12 as per the QMS of the organization. It should be noted that the sampling locations for the study will be selected in such a manner which will suffice the sampling requirement for all the projects adhering to the NABET guidelines.Based on the understanding and experience of the Functional Area Experts environmental monitoring was conducted in the months of Dec-17 to Feb 18. Therefore in the case of sampling locations for groundwater, surface water, soil and noise are common. For ambient air quality, for monitoring the conditions at the project site individual monitoring was conducted at the premises of each industry keeping the rest of the sampling locations common as inferred from the wind pattern from the secondary data. 3.2 Meteorology It is known that meteorological conditions around us influence not only the levels of pollution but also their dispersion on local, regional, national as well as global scale.

b. Relative Humidity: The presence of relative humidity indicates the level of water vapour in the atmosphere. From the data it can be inferred that relative humidity was observed to be lowest in winter season and highest in the monsoon season. The highest average of relative humidity was observed to be up to 98 % in the monsoon season during July and August. It should be noted that on rare occasions in the winter season relative humidity was observed to reach the maximum of 98%. c. Rainfall: The months of July and August are considered to be the months which receive maximum rainfall of the year. The data indicates that average annual rainfall received amounts to 1850 mm each year. d. Atmospheric Pressure: Changes in pressure influence the vertical mixing of the air. Thus variation in pressure is important for vertical as well as horizontal mixing of pollutants present in the atmosphere. The change in atmospheric pressure is experienced diurnally, nocturnally as well as seasonally. The maximum average atmospheric pressure is experienced during the winter season while minimum average atmospheric pressure is experienced in the rainy season during the months of June. e. Wind direction and Wind speed: The data for wind speed and wind direction is presented separately using wind rose diagrams in Fig. 3.3 to 3.5. The wind dispersion during 2012- 2016 is presented in Fig. 3.3, while the wind pattern during Dec - Feb (sampling period) during 2012 - 2016 is presented in Fig. 3.4. The Fig. 3.5 presents the meteorological conditions during the study period of Dec17 to Feb 18.
3.2.2 Site Specific Meteorological Data Monitoring for micro meteorological data was carried out on continuous basis at the project site. The parameters selected were wind- speed, wind-direction, rainfall, temperature and relative humidity. Monitoring was carried out using an automatic weather monitoring station at the project site. The station was installed keeping in view the free exposure of sensors to atmosphere and minimum interference from the nearby structures.

Chapter 3 –Description of the Environment presented in Table 3.2. The highlights of the meteorological factors considered for monitoring for the present study are discussed as under: Table 3.2 Site Specific Micro Meteorology Data (Dec17 to Feb, 2018) Temperature Relative Wind Speed Dominant Wind Rainfall Months (OC) Humidity (%) (Km/hr) Direction mm Min Max Min Max Min Max (Blowing from) Dec 17 16 14.6 34.6 24 94 0 14 North West to Jan 18 00 14.2 32 21 98 0 18 South East Feb 18 00 13.6 31.8 24 93 0 18
Temperature Temperature during the study period was found to vary from 13.60C to 34.60C during the study period. Relative Humidity Relative humidity during the study period was found to be maximum 98 % & minimum 21 % Wind Speed and Wind Direction The wind rose diagram representing the summer season is shown in Fig 3.5. A review of wind rose diagram shows that predominant winds are mostly from North West to South East. The hourly minimum wind speed was recorded to be 0 Km/hr & maximum was observed around 18 Km/hr. Interpretation: Meteorology forms the base of any dispersion studies. With this understanding Windrose diagrams using secondary data obtained from Indian Meteorological Department (IMD) for annual data (5 Years) & sampling period (Dec to Feb of year 2012 to 2016) have been plotted. The wind rose prepared from secondary data for sampling period of Dec to Feb, indicates that about 44% of the time, wind was observed to be blowing from North West direction. At the same time the windrose diagram based on primary data (for the monitoring period) indicates that around 42% of the time the wind is blowing from the North West direction. For determining the sampling locations of air quality monitoring it is important to understand the distribution of wind direction during the monitoring period, i.e. during the months of Dec to Feb.

Chapter 3 –Description of the Environment
According to the interpretation of the secondary data for meteorology it is concluded that the prominent upwind direction is North West. Therefore the monitoring stations can be selected based on the prominent wind direction identified.
Comments: The collected secondary data and the primary data have been compared and analyzed to verify the quality of the data. The comparison of the secondary meteorological data (for Dec to Feb, 2012-2016) with the primary data (Dec 17 to Feb 18 2017) monitored at site is summarized as under: Minimal variation in the values is observed in the two data sets. For instance the minimum temperature recorded at the monitoring site was 13.6C and the same from the secondary data was observed to be 13.4 C, while the maximum temperature at project site was measured to be 34.6C and that from the meteorological data from IMD was observed to be 33.6C. The data for minimum relative humidity recorded at site was noted to be 21% and that from secondary data was observed to be 20%. At the same time maximum relative humidity recorded at site was 98 % while the same according to the secondary data was 98%. It can be inferred from the above data that the pre-dominant wind direction during the monitoring period is similar in the secondary as well as primary data collected from the monitoring station.
3.3 Ambient Air Quality Monitoring The baseline data for the proposed project is collected during month of Dec 17 - Feb 18. The monitoring of ambient air quality around the project site provides an understanding about the prevailing level of environmental pollution in the atmosphere. For the purpose of air quality monitoring a study area of 10 km radius from project site has been considered. Based on the observations of study area from satellite imagery it can be said that the

SEEPL/EIA/F/IND/ALL/001/2017-18/00
Chapter 3 –Description of the Environment construction etc,.The minimum concentration at location A8 can be said due to its remote location and minimal human activity in and around the monitoring station. Therefore experiences minimal levels of pollution.
PM2.5
The major source of PM2.5 is said to be the combustion of fossil fuels, fire wood, etc. The 3 maximum of PM2.5 (51.8 µg/m ) during the study period was recorded at location A1, whereas the minimum 17.0 µg/m3 concentration was recorded at A8 location which is a remote area. The minimum concentration indicates that the area experiences minimal combustion and vehicular activity. On the other hand high concentration at location A1 indicates that the area experiences high emissions from combustion of fossil fuel and vehicular movement in the surroundings. It is important to note that location A1 lies in the surrounding of heavy urbanization which experiences constant movement of vehicles which can be said to be the major cause for increase in the concentration of PM2.5. The average concentration of PM2.5 during the study period was computed to be in the range of 21.7-44.2 µg/m3.
Sulphur dioxide (SO2)
High level of SO2 in ambient air indicates the presence of combustion of fossil fuel in the vicinity. The ambient air monitoring results indicate that the highest average concentration of
SO2 is experienced at location A1. The emission from other industries & constant traffic and regular movement of heavy vehicles which are diesel driven around the MIDC area can be considered as the principle source of emission for SO2. The average concentration of SO2 recorded at all the monitoring locations during the study period ranged between 18.9-29.1 µg/m3 respectively. It should be noted that maximum average concentration was recorded at location A1 while the lowest can be observed at location A6. The location A6 is scarcely populated and is remotely located. Hence low levels of anthropogenic activities and emissions are observed in the area. The concentration of SO2 were within the CPCB limit at all the location.

The maximum 24 hourly value of NOX was recorded at the monitoring location A1 (50.5µg/m3) & A5 (50 µg/m3) whereas the minimum concentration of NOx was recorded at location A8 (18 µg/m3). It should be noted that the location A8 was observed to have minimal vehicular activity resulting in minimal concentration of pollutants.
Carbon monoxide (CO) The anthropogenic source of CO is due to incomplete combustion of fuel majorly in absence of air. The maximum concentration of CO estimated at all locations during the study period can be observed to be within 1.2 to 2.1 mg/m3 respectively. The minimum concentration at all locations ranged between 0.5 - 0.9 mg/m3. The highest average is calculated at location A1 and the lowest average was estimated to be at location A7.
Monitoring of Additional Parameters: The monitoring for additional parameters in ambient air namely Ozone, Lead, Ammonia, Arsenic, Benzene,Nickel &Benzo(a)pyrene was conducted within the project premises (A1 location). The results for these parameters are presented in Table 3.6. It can be stated that concentration of Benzene, Benzo(a)pyrene& Ammonia was found to be below the detection limit. The values of Ground level ozone were estimated to be within the range of 21 to 30.6 µg/m 3. The average concentration was computed to be 25.5 µg/m3. The presence of heavy metals such as lead, arsenic and nickel were estimated to be below the detectable limits and thus their presence can be said to be negligible. As mentioned earlier the concentration of VOCs was also monitored at the project site. The results revealed that the concentration was found to be below the detection limit as presently.

The surface water resources in the study area as studied from the satellite imagery appear to be few in number, especially for the purpose of drinking water. The primary surface water bodies in the study area are Kal & Savitri river’s in the south direction. Apart from this the study area has presence of reservoirs, lakes, located within the 10km radius or the study area. The Savitri receives water on its course from different streams and rivulets on its course from North of the project site to South West of project site. The sampling locations for the water bodies were finalized after reconnaissance survey and consultation with the functional area experts from the respective areas. 3.4.2 Probable sources of surface water pollution in the study area The Savitri River Stretch in the study area is subjected to industrial and domestic discharges from the MIDC area. It is to be noted that the river stretch is also subjected to discharge of domestic effluent from the residential area of Mahad, Birwadi and other surrounding villages.

Chapter 3 –Description of the Environment observed to be ranging between 81 to 130 mg/l. The maximum value of hardness was recorded at SW3 and the minimum value was recorded at SW8. The concentration of Total Dissolved Solids was estimated in the range of 154 mg/l to 319 mg/l. The maximum concentration of Total Dissolved Solids (TDS) was observed at SW3 whereas the minimum TDS concentration was observed at SW8. It should be noted that the variation observed in the concentration of TDS can be said to be marginal. The Chemical Oxygen Demand (COD) & Biochemical Oxygen Demand (BOD) values were calculated to be in the range of <4mg/l to 90 mg/l &<3mg/l to 32.1 mg/l respectively. The presence of heavy metals like Arsenic, Mercury, Lead, Chrominum, Zinc, Nickel & Cadmium were found out be below the detection limit for all the water samples. It should be noted that the iron content in all the samples of surface water bodies were below the detection limit. Fluoride was detected in lower concentrations ranging from 0.227-0.454 mg/l. The nitrate concentration was observed to be in the range of 2.3 – 7.5 mg/l. Surface runoff from agricultural fields using the fertilizers can be the major source of nitrate. The microbiological samples for total coliforms were in the range of 13-92 org/100 ml and E-coli was found to be present in SW- 2 to SW-5 in the rest of the samples it was absent.
It should be noted that in case of the selected water bodies (SW-1 to SW-5) classified under category “E”, the parameters were found to be within the prescribed limits. The results for location SW-6 , SW-7 & SW8 categorized in category “B” indicated that all the parameters were found to be within the prescribed limits except for SW-7 the BOD value was above the prescribed limit. Hence for SW-7 the water can be continued for its designed use as per Inland Surface Water Standards after disinfection and necessary treatment.

As per the Standard ToR sampling was decided to be carried out at 8 locations. The sampling locations were selected on random basis subject to the availability and feasibility. The water quality monitoring network was designed with the intention to evaluate the prevailing ground water quality in the study area. The sampling frequency was once in a season (study period – Dec 17 to Feb, 2017). The details of the methodology for ground water sampling is provided in Table No. 3.12 3.5.4 Selection criteria for water quality sampling locations The sampling sites were selected considering the following criteria - 1. Topography of the study area Pattern. 2. Areas which may be affected due to the activity. 3. Any probable locations with open discharge of sewage or waste water. 4. Location of any solid waste dumping facility in the vicinity of the project site. In cases where the sampling locations are situated close to MIDC areas, ground water pollution can be said to be affected by underground (illegal) discharging of waste water by the industrial units. If any such cases are reported then sampling is conducted in the surrounding area. Based on the above criteria eight sampling locations were selected for the present study. These locations are marked on SOI map in 3.11. The results for analysis conducted are presented in Table 3.13. These results are compared with the drinking water standards provided by IS (Table 3.14). The aspects related to Sample Collection, Preservation and Transportation are described in detail in the above section 3.4.5.

It should be noted that the microbiological analysis of allthe samples indicate that e-coli was absent in all the ground water samples. The presence of total coliforms except for GW1 ,GW6& GW8 were in the range from 15-26 Org/100 ml indicate that the anthropogenic activity in the surrounding area can be a possible source of contamination. It should be noted that the concentration of the coliforms were higher in the dugwell compared to the concentrations observed in the borewell samples. The fluoride concentrations are ranging between 0.20 - 0.434 mg/l. The presence of the fluoride in all the water samples is mostly due to geogenic in nature. The nitrates concentrations were ranging between 2.0 -9.3 mg/l well below the acceptable limits of drinking water. The probable sources of nitrates in the ground water could be the use of fertilizers in the nearby agricultural activity. The COD and BOD values of all the ground water samples were found to be below the detection limit. Thus based on the above results it can be stated that the water from the said samples can be considered fit for consumption and potable purpose with basic primary treatment. The water can be used for domestic utilization and gardening without any treatment.
3.6 Noise Level Monitoring Noise can be defined as a sound, especially one that is loud or unpleasant or that causes disturbance. High and prolonged or continuous exposure to noise levels is known to cause deleterious effects on the humans, plants and animals. In some cases short term exposure to high noise levels has been considered equally dangerous for humans and animals. In future Noise level pollution in the rural or urban areas can be of great concern. Monitoring of Noise level provides an insight pertaining to the prevailing conditions of noise in the surrounding areas. This data when available is considered as a baseline data for a given area and based on the data predictions in increase in noise levels are carried out. 3.6.1 Noise generation sources in the study area As the project site is located in the notified industrial area, various sources of noise generation can be said to be arising from the various industrial activities carried out in the surroundings. Other sources contributing to high noise levels can be attributed to movement

Chapter 3 –Description of the Environment of heavy vehicles in the nearby areas. Apart from the heavy vehicles, the number of public and private vehicles plying in the region can be said to contributing towards noise pollution. The stone mining activities were identified in the study area which can be potential source of noise pollution. Noise can be said to generate through various industrial processes and machineries operating in the industries. 3.6.2 Monitoring Details For the present study Noise monitoring was carried out as per the Central Pollution Control Board guidelines on 24-hourly basis at 8 locations in 10 km radius of the study area. Monitoring was carried out on weekly basis (once in a week). The locations were decided as per the guidance of the Functional Area Experts and are presented in Fig 3.9 on Google Earth Img. The noise levels monitored were grouped into day and night time noise levels. The day time is considered to be during 6 am to 10 pm and night noise time is considered between 10 pm to 6 am at all the locations in the study area. The noise monitoring was carried out by a precision integrated noise meter of baseline technology Model No. 2511. It should be noted that location N1 is situated in the industrial area while rest of the locations are categorized into rural and residential areas. The standards used for comparison of the noise levels are therefore used as per the standards prescribed regulations of CPCB. 3.6.3 Criteria for selection of noise level monitoring locations The locations for representative noise monitoring were selected considering the following criteria:- 1. Identification of probable sources. 2. Identification of Sensitive Receptors around the project area. 3. Individuals/Areas likely to be affected due to the expansion activity. 4. Topography of the study area. 5. Site feasibility related to accessibility, etc. The details of the monitoring locations are provided in Table 3.15.

Chapter 3 –Description of the Environment
Geologically Konkan lowland is a platform of marine denuation raised to form a narrow plain. The steep scarps facing the coast and some-what gentle slopes towards the east believed to be due to extensive faulting of the ghat region. The geology of the entire district consists of dark colored volcanic lava and laterites which date back to Mesozoic period. These are spread out in the form of horizontal sheets and beds and have innumerable spurs, hills, ridges, peaks and plateaus. In the plains and valleys, the lava flows occurred below a thin blanket of soil which varies in thickness from place to place. Petro logically the lava flows in the district are in horizontal way with incredible uniformity in their composition, appearance and texture corresponding to basalt with an average specific gravity of 2.9. The basalt is a predominant rock formation of the district. The basalts are usually dark grey to grey in color and are hard compact and tough and fine to medium grained structure. Deccan Trap rock which is completely impervious to percolation, these causing an accuse shortage of water in summer. Beds of laterite can be said to be, usually formed by mechanical and chemical disintegration brought by atmospheric agencies on the underlying trap, cap of several picks and lofty ridges in the district.
The types of rocks present in the Raigad region can be highlighted as under:
Deccan Trap Basalt Ground water in Deccan Trap Basalt occurs mostly in the upper weathered and fractured parts down to 10 – 15 m bgl under unconfined condition. The water bearing strata at deeper depth exists under semi confined to confined conditions. The dugwells in these areas show rapid decline in water level during post-monsoon period and practically go dry in peak summer. In foot hill zones the water table is relatively shallower near water course. The yield of dugwells tapping upper phreatic aquifer ranges between 45 to 60 m3/day, whereas that of borewells varies from 0.50 to > 20 m3/hr. depending upon the location.

Chapter 3 –Description of the Environment
The Alluvial deposits are found along the coastal areas in few isolated patches having limited areal extent as Beach Sand and along the course of major rivers. In the alluvial deposits, primary porosity is due to the inter-granular pore spaces making sands and gravels good water bearing formations. The ground water occurs under phreatic/unconfined aquifer at relatively shallow depths of 3-5 m and their yield ranges from about 18 to 43 m3/hr.

Interpretation
The analysis reveals that TS 1 is subjected to heavy and continuous traffic which is acceptable as it is a junction which is connected to the National Highway. While the location TS2 being located at junction of feeder road and MIDC road is estimated to receive low traffic as compared to TS1.
3.10.10 Increased traffic scenario due to the expansion project The transportation of raw materials & finished goods for the existing unit in operation and the production enhancement activity will be mainly done by tankers/trucks.It is estimated that 30 trucks per day will make to and fro trip from the project site. As described in the above section the transportation activity will mainly take place by National Highway 66. As an initiative for efficient traffic management the project proponent will ensure that transportation activity will be done mainly during non peak hours to avoid the peak hour traffic, however to assess the increased traffic scenario due to the project the increased fleet of 30 trucks/tankers per day has been considered during the peak hours at all the two junctions.It is estimated that due to the proposed activity increased PCUs will be as given in Tables 3.31 and Table 3.32.

Prominent vegetation existed all along the Solamkond to Kijaloli Mohalla hill running north of the project site. Also vegetation clad hills existed in the along the Bhave, Kharvali and Borgaon villages towards East, SSE & South directions from the project site in the inner 5 km radial study area which are mainly Reserve Forest patches.
Buffer study area
The major part of the outer 5 km radial study area was also a hilly tract with moreover uniform cover of vegetation spread along the entire outer 5 km radial study area.
The observed vegetation along these hills & hillocks was of Southern Tropical Dry Deciduous forest type as found across the entire range in the Raigad District.
General features of the prevailing aquatic ecosystem in study area
The aquatic system in the study area is largely represented by westerly meandering Kal River which is joined by several other rivers during its course in the study area such as right tributary also known as Kal River joining at Amshet, left tributary viz. Bhaovira River joining at Birwadi, further right tributary viz. Savitri River joining at Bhorao thus the Kal River while escaping the study area is known as Savtri River which continues it further meander and drains into Arabian Sea at Harihareshwar approximately at an aerial distance of 43.0 km from the study area. Apart from the above mentioned rivers one artificial surface water reservoir is present near Warandh Village.
Note: Since any of the project related activities during commissioning & operation phase will not be associated with the prevailing surface water bodies in the study area in terms of withdrawal or disposal/discharge hence no impact is envisaged on the water bodies so the studies pertaining to aquatic ecology such as Plankton, Chlorophyll, Benthos, Fisheries etc. have been kept out the purview of this study.

4.1.2 Operation phase
4.1.2.1. Identification of Sources
Emissions from fuel burning For operational phase of the project stack attached to 6 TPH steam boiler (Stack No.1), stack attached to 850 kg/hr. steam boiler (Stack No.2), stack proposed to 15 TPH steam boiler (Stack No.3) & common stack proposed to 6 & 2 lack kilo. cal./hr. themic fluid heaters (Stack No. 4) are considered as point sources of emission. The primary fuel that would be used for boilers & thermic fluid heaters operations will be Indonesian Coal & Furnace Oil, the Sulphur content of Indonesian Coal & F.O is 0.56% & 4% respectively.
Gases and vapors from manufacturing process are identified as a second source of emission, which will be passed through process scrubbers to mitigate the process emissions. Scrubbed gases from scrubber will be released through a stack of 5.0m above roof level.
One of the major sources of fugitive emission generation can be due to handling, storage and transportation activity of raw materials. All raw materials & fuel will be stored in tanks, drums &bags. Sources of VOC emissions from the project would be from storage area due to handling & operating the solvent drums, loading unloading of solvents etc. Vehicle used for transporting raw materials & finished products also contributes to dust generation & emissions of gases like NOx due to fossil fuel burning.
4.1.2.2. Prediction of Impacts
For quantitative impact analysis on air quality due to expansion activity, air dispersion modeling is performed. Criteria pollutants like PM10, PM2.5, SO2, NOx & CO generated from operation of steam boiler & TFH were considered for air modeling.
AERMOD 8.2 developed by USEPA and authorized by CPCB is used for air modeling simulation which is based on steady state Gaussian plume equation.

Impact of raw materials transport on surrounding environment:
In most cases, transport of raw materials, general supplies and final products causes an increase in traffic around the facility. It is anticipated that 10 trucks per day would be used for transportation of raw materials and final product. Transportation and environment are paradoxical in nature. The transportation activities convey substantial socio-economic benefits, but at the same time transportation is impacting environmental systems.
The impacts of the transportation can be minimized by following aspcets.
Planning Transport development:
The transportation of the raw materials and final product will be done mostly by road. Road transportation would be the most feasible option available for the project proponent as it will be the least expensive in terms of investment, maintenance and security.
Construction of transport infrastructures:
The project is located in notified MIDC Mahad industrial area hence the existing transport infrastructures such as MIDC roads & city roads around the project will be utilized.
Maintenance and operation of transport infrastructures:
Maintenance & operation of the transport infrastructure would be carried out by the MIDC/ Local Administration. Facilities like street lighting, traffic management in the peak hours and maintenance of the road will be taken care by the MIDC/Local Administration.
Use of transport infrastructures and vehicle maintenance:
The transportation of raw hazardous, flammable and toxic materials (Raw materials & Products) would be done according to the rule of Central Motor Vehicle Rule, (CMVR) 1989. Transportation of material carrying vehicles will mainly take place through National Highway 66.

4.2.2.2 Impact predicted
The wastewater generated from the project activity if discharged to the Common Effluent Treatment Plant (CETP) without prior in-situ treatment, it can cause the breakdown of the common effluent treatment plant as it will contain high TDS concentrations. Also if the untreated waste water is by passed to the MIDC drains it will results in the contamination or polluting the water body at final discharge point. The prolonged unscientific discharge of the untreated waste water may lead to the contamination of the nearby surface water bodies, soils in the near vicinity and ultimately resulting in polluting the underground water reserves through percolation from soil. The release of untreated effluent will ultimately affect the overall ecology & agricultural productivity in the surrounding area.

Precautionary management/mitigation measures to be adopted for prevention of soil contamination
In order to avoid risk of soil contamination within the project plot & study area due to unforeseen leakage the project proponent is robustly advised to concrete pave the entire ETP area. Also project proponent to ensure safe working & periodic maintenance of ETP by establishing written SOPs (Standard Operating Procedures) & training the ETP operating staff with the same.
All raw materials & products should be stored in dedicated closed warehouses/storage areas with leak proof flooring & walls. Production area should be covered with “Acid/Alkali” proof bricks with adequate drainage system connected to ETP.
Transportationof chemicals (raw materials/products) & hazardous waste will be mainly done by trucks/tempos however the unforeseen events of accidental spillage are not predictable which makes it difficult to install pre event control measures. However for such instances project proponent is robustly advised to develop & deploy Offsite Emergency Contingency Plan & develop related Standard Operating Procedures & provide training about the same concerned personnel to tackle any unforeseen event.
Hazardous waste will be stored in dedicated hazardous waste storage area made of thick concrete paved flooring with HDPE lining & in any case hazardous waste should not be stored more than 90 days & to be disposed off to CHWTSDF. Other industrial waste such as plastic waste, packing material, cleaned empty drums/carboys/containers will be stored in a dedicated waste storage area & such waste will be returned to supplier/sold to authorized recycler.
For proper dispersion of pollutants in atmosphere, stack with appropriate height will be provided as per the CPCB guidelines.

5.3 Biotic environment
Nevertheless the impacts associated with any kind of proposed activity on the environment cannot be completely nullified however the severity of such impacts can be minimized to a great extent by advocating suitable mitigation measures.
4.4.4 Anticipated impacts (Construction phase)
Impacts during construction phase
No construction activity is required as the production enhancement will be carried out using high volume capacity reactors replacing existing reactors of less capacity.
Evaluation of vegetation felling/clearing activity
The project in consideration is a brown field activity which will be executed within the premises of an existing manufacturing plant by replacing existing reactors with high volume capacity reactors. Hence any sort of vegetation felling/clearing activity is not involved.
Evaluation of habitat loss
The project plot in consideration was already subjected to industrial type of use and was not inhabited by any faunal species hence habitat loss is anticipated.
4.4.5 Anticipated impacts (Operational phase)
Generally the activities which may have adverse impact on the biotic environment during the project operational phase may be due to unforeseen / deliberate release of treated/untreated effluent, disposal of hazardous waste on the ground or in the water bodies in the study area. However the proposed project has made following provisions for the effluent & hazardous waste management.

Chapter 4: Anticipated Environmental Impacts & Mitigation Measures
The hazardous wastes generated during project operational will be either sold to authorized recyclers or will be sent to Mumbai Waste Management Ltd. - CHWTSDF at Taloja for further processing & disposal.
The only direct possible impacts from the proposed project activities may be due to following activities:
1) Air emissions from burning of fuel for operation of utilities like Boiler, D.G set & manufacturing process related emissions if at all escapes the industrial area.
2) Accidental/Unforeseen disposal of hazardous chemicals (raw materials & finished products) & hazardous wastes within the study area.
Precautionary measures to be adopted during the operational phase 1) AstecLifesciences Ltd. will ensure that the during the operational phase at no point of time in whatsoever manner untreated/treated effluent will be subjected to disposal on land or in water bodies within the study area.
2) ALSL will ensure that permitted quantum of treated effluent is sent to CETP & additional effluent is recycled and also it will be ensured that the hazardous waste is not disposed of at any other place except the designated CHWTSDF.
2) In order to minimize the air emissions at the source itself provision of APCD’s (Air Pollution Control Devices) such as Process scrubbers (proposed) is made for manufacturing process related emissions & adequate stack height for existing & proposed boiler stacks will be provided as per CPCB guidelines.
3) As a precautionary measure industry should ensure that at no point of time during the operational phase of the project the concentrations of air emissions should not exceed the prescribed levels.

Assessment of presence of any endemic, conservation importance species in the study area
The recorded 85 plant species, 29 bird species, 1 mammal and 6 reptiles are fairly common and have a wide range of presence and abundance across the entire Raigad District, moreover any of the floral & faunal species in the study area does not belong to any categories of conservation concern as per the IUCN & WPA 1972.
Impact assessment
Proposedproject activity does not pose any threat to any species of conservation importance also does not involve any sort of liquid or solid discharge/disposal on the ground or in the water bodies within the study area & project plot being located well within the precincts of an area which already prevails industrial type of use no adverse impacts are anticipated on the surrounding biotic environment.
5.4 Land environment
5.4.1 Impact identification
Generally the developmental activities such as construction & development of Building/Township/Industrial Estate/Special Economic Zones which involve comparatively larger areas tend to change the prevailing land use & land cover aspects directly.
Also the influx of people associated with such project activities has the potentiality of changing surrounding land use & land cover aspects by way of new settlements/setups & thus promoting various other infrastructural activities there by inducing land use/land cover changes indirectly.

Chapter 4: Anticipated Environmental Impacts & Mitigation Measures
The proposed activity is a production capacity expansion of the existing unit located at Plot No. -16, 17, 18 and B-21 and will be carried out by replacing existing equipment by new higher capacity equipment.
Since there is no requirement of any new/ additional land hence none alternative sites were considered for the proposed expansion project.
This is industrial type of land use hence no changes in the existing land use - land cover aspects of the study area are anticipated.
5.5 Socio economic environment
It is envisaged that the existing project & the proposed expansion activity will help to some improvements in the locale specific socio-economic aspects in the nearby human habitations to the MIDC area. Since the proposed expansion will be carried out within the existing plant areaand hence no impact on external human settlements is envisaged also project will not have any major impact on the local level population growth, since existing 160 no. man power is sufficient for the expansion activity. Hence increase in the population and related strain on infrastructure of the study area is not envisaged. Better literacy rates are possible due to assumed better economic conditions of the people in the project concerned area. Better literacy means better social status and thereby improved lifestyle. This will be a positive impact due to the existing and proposed capacity expansion.
5.6 Odour
5.6.1 Identification of source
Odour sources can be continuous or intermittent, point sources (for example chimneys, stacks or building vent/exhaust pipes), area sources (for example stockpiles, ponds or open-topped tanks) or volume sources (for example, a building with many openings from which odour escapes). The

Chapter 4: Anticipated Environmental Impacts & Mitigation Measures sources within the site boundary and any nearby sources beyond the boundary they could contribute to cumulative odour impacts. It is important to include fugitive sources as these often make an important contribution to the odour impacts. In the operational phase the component which will contribute to the odour generations are working of waste water treatment plant, raw materials and chemicals handling in the industry, working emission of the solvents storage tanks etc. Sources which will lead to the generation of odour are leakage of solvent/chemical from the storage drums/pipeline/reactors, evaporation of acid as acid fumes, domestic waste, handling of raw materials, also handling of sludge and reaction waste etc.
5.6.2 Impact prediction
Exposure to odors could result in health effects ranging from none, to mild discomfort, to more serious symptoms. Some chemicals with strong odors may cause eye, nose, throat or lung irritation. Strong odors may cause some people to feel a burning sensation that leads to coughing,wheezing or other breathing problems. Workers/People coming in contact who smell strong odors may get headaches or feel dizzy or nauseous. If an odor lasts a long time or keeps occurring, it also could affect mood, anxiety and stress level.
5.6.3 Mitigation measures
Mitigation measures that can be implemented for controlling the odour are given below,
Provision of Ventilation and Exhaust: The flow of air and exchange in plant area where chemicals are handled will largely impact odour. Storage conditions of volatile organic compounds with odour will also significantly contribute to odour. In normal circumstances it is best to keep the odour emanating materials under closed conditions. Also providing adequate exhaust in the area can control odour. Well documented SOPs on chemicals handling and trained operators can hugely control the release of odour in plant Supervision and maintenance: Equipments are very well maintained and the company has strong Asset Integrity plan philosophy and plan. A well documented Preventive, and predictive maintenance plan is prepared for all equipment, machines, and assets. Good

SEEPL/EIA/D/IND/ASL/001/2017-18/00
Chapter 4: Anticipated Environmental Impacts & Mitigation Measures
Housekeeping: Decay Evaporation of odorants from stored decaying material may often lead to odour emission. Good housekeeping may eliminate the problems. Provision of Containment: The preventive measures or changed process parameters are not enough to avoid annoying emissions of odorous compounds from a plant, it must be placed in a building equipped with ventilation and, where required, air cleaning equipment. It may be necessary to have non-opening windows and automatic gate and door closing devices, and to provide a negative pressure in the building. Odour nuisances can be prevented either by cleaning of exhaust air or by dilution in outlets. Increasing Air Exchange: The exchange of air surrounding an odorous process is large the emitted odorants will be diluted. But if the odour comes from evaporated material, the emission may increase. In normal circumstances it is best to reduce the amount of air which gets in contact with odorous materials. In this way odour control equipment will be required. Good Housekeeping: Decay Evaporation of odorants from stored decaying material may often lead to odour emission. Good housekeeping may eliminate the problems.

A) The amount of water required for firefighting purpose can be estimated by the below formula:
Water required in liters per minutes = (A + B +C + D)/20
A) The total area in sq.mtr of all Floors including galleries in all building of the Factory
B) The total area in sq.mtr of all Floors and galleries including open spaces in which combustible materials
C) The total area in sq.mtr of all Floors over 15 m above ground level
D) The total area in sq.mtr of all floors of buildings other than those of fire resisting construction of various floors is so certified by any fire association or fire insurance company
Water required in liters per minutes = (2272 +505 + 1097+ 61.15)/20
= 196.73 lit/min
= 0.197 m3/min
The quantity of firefighting tank is 300 m3. Therefore the capacity is justified. As the back-up water supply will last for 25 hours.
Time (min) = [Total water in firefighting tank (m3)]/water required m3/min
= 300/0.197
= 25.42Hrs.
The pump capacity in the plant is 171m3/hr, therefore according to the discharge capacity of the pump installed. The back-up time by which the tank will be empty is calculated below,

Interpretation Keeping in view the nature of the emergency, two levels of co-ordination are proposed. In the case of an On Site Emergency, resources within the organization would be mobilized as explained in the above section and in the event of an extreme emergency; local authorities‟ help would be sought. In the event of an emergency developing into an offsite emergency, local authority and District Emergency Authority (normally the Collector) would be appraised and under his supervision, the Off Site Disaster Management Plan would be exercised. The detailed risk analysis has indicated that the toxic effects would be felt outside the factory. Hence it is suggested that in case of such an emergency event people (outside the company) are advised to stay indoors, complete evacuation is not recommended. For this purpose, the offsite emergency plan has been highlighted in the below section, for the facilities that are available locally, i.e. medical, transport, personnel, rescue accommodation, voluntary organizations etc. would be mustered. Necessary rehearsals and training in the form of mock drills should be organized in consultation with the district emergency authority.
7.5 Off-Site Emergency Preparedness Plan
The off-site plan will be prepared with the help of the local district authorities. The proposed plan will be based on the following guidelines.
7.5.1 Introduction Off-site emergency plan follows the on-site emergency plan. When the consequences of an emergency situation go beyond the plant boundaries, it becomes an off-site emergency. Off- site emergency is essentially the responsibility of the public administration. However, the
Sadekar Enviro Engineers Pvt. Ltd. Chapter 7- 53 Environmental Impact Assessment Report for Expansion of Pesticide Manufacturing and Formulation unit of M/s Astec LifeSciences Ltd., Plot no. B-16, 17, 18, & 21, MIDC, Mahad, Raigad, Maharashtra.
SEEPL/EIA/F/IND/ALL/001/2017-18/00
Chapter 7: Additional Studies
factory management will provide the public administration with the technical information relating to the nature, quantum and probable consequences on the neighboring population. The off-site plan in detail will be based on those events, which are most likely to occur, but other less likely events, which have severe consequence, will also be considered. Incidents, which have very severe consequences yet have a small probability of occurrence, should also be considered during the preparation of the plan. However, the key feature of a good off-site emergency plan is flexibility in its application to emergencies other than those specifically included in the formation of the plan. The roles of the various parties who will be involved in the implementation of an off-site plan are described below. Depending on local arrangements, the responsibility for the off-site plan should either rest with the works management or, with the local authority. Either way, the plan should identify an emergency coordinating officer, who would take the overall command of the off-site activities. As with the on-site plan, an emergency control centre should be set up with whom the emergency coordinating officer & emergency planning officer can operate. An early decision will be required in many cases on the advice to be given to people living "within range" of the accident; in particular, whether they should be evacuated or told to go indoor. In the latter case, the decision can regularly be reviewed in the event of an escalation of the incident. Consideration of evacuation may include the following factors: In the case of a major fire but without explosion risk (e.g. an oil storage tank), only houses close to the fire are likely to need evacuation, although a severe smoke hazard may require this to be reviewed periodically If a fire is escalating and in turn threatening a store of hazardous material, it might be necessary to evacuate people nearby, but only if there is time; if insufficient time exists, people should be advised to stay indoors and shield themselves from the fire For release or potential release of toxic materials, limited evacuation may be

appropriate downwind if there is time. The decision would depend partly on the type of housing "at risk". Conventional housing of solid construction with windows closed offers substantial protection from the effects of a toxic cloud, while shanty house, which can exist close to factories, offers little or no protection.

with thecontent, he may direct the occupier to supply further information to the workers, authority, general public & District Emergency Authority as deemed necessary.
7.5.3 Role of the Emergency Coordinating Officer The various emergency services will be coordinated by an emergency coordinating officer (ECO), who is designated by the District Collector. The ECO will liaise closely with the Site Controller. Again, depending on local arrangements, for very severe incidents with major or prolonged off-site consequences, the external control should be passed on to a Emergency Planning Officer of the local authority administrator.
7.5.4 Role of the Local Authority The company will enter into an agreement with the Emergency Planning Officer (EPO) of the area, within whose jurisdiction the factory is situated for the Emergency officer to take appropriate steps to inform the general public outside the factory who likely to be affected by an accident. The information in the prescribed format would be shared with the EPO by the site controller. The duty to prepare the off-site plan lies with the local authorities. The Emergency Planning Officer (EPO) appointed should carry out his duty in preparing for a whole range of different emergencies within the local authority area. The EPO should liase with the site controller for ensuring that the plan is continually updated. It is the responsibility of the EPO to ensure that all those organizations, which will be involved off site in, handling the emergency, know of their role and are able to accept it by having for example, sufficient staff and appropriate equipment to cover their particular responsibilities. Rehearsals for off-site plans are organized by the EPO.
7.5.5 Role of Fire Authorities The control of a fire should normally be the responsibility of the senior fire brigade officer who would take over the handling of the fire from the site incident controller on arrival at the site. The senior fire brigade officer should also have a similar responsibility for other events,

such as explosions and toxic release. Fire authorities in the region should be apprised about the location of all stores of flammable materials, water and foam supply points, and fire- fighting equipment. They should be involved in on-site emergency rehearsals both as participants and, on occasion, as observers of exercises involving on-site personnel.
7.5.6 Role of Health Authorities Health authorities, including doctors, surgeons, hospitals, ambulances, and similar other persons/institutions should have a vital part to play following a major accident, and they should form an integral part of the emergency plan. For major fires, injuries should be the result of the effects of thermal radiation to a varying degree, and the knowledge and experience to handle this in all but extreme cases may be generally available in most hospitals. For major toxic releases, the effects vary according to the chemical in question, and the health authorities should be apprised about the likely toxic releases from the plant, which will enable them to deal with the aftermath of a toxic release with treatment appropriate to such casualties. Major off-site incidents are likely to require medical equipment and facilities inadditional to those available locally, and a medical "mutual aid" scheme shouldexist to enable the assistance of neighboring authorities to be obtained in theevent of an emergency. 7.5.7 Role of Police Authority Formal duties of the police during an emergency include protecting life and property and controlling traffic movements. Their functions should include controlling bystanders, evacuating the public, identifying the dead and dealing with casualties, and informing relatives of dead or injured. 7.5.8 Role of Pollution Control Board On receipt of information officer of the pollution control board shall proceed to the affected site. Conduct investigation including collection of data. Ensure that the spills have been contained with no further damage possible to humans and environment. Further to declare the area fit for re-entry after the decontamination is completed. In case of an environmental

Chapter 10: Environmental Management Plan
CHAPTER 10: ENVIRONMENTAL MANAGEMENT PLAN 10.1 Introduction Every industrial development is associated with the positive and negative impacts on environmental components.Thoughthe probable negative impacts cannot be nullified completely the much required developmental activities cannot be impeded. Environmental Impact Assessment helps in identifying potentially environmental impacts of a proposed project activity. Based on the finding of the impact assessment, Environment Management Plan is devised to minimize the adverse impacts and enumerate various steps to be taken for improvement of the environment. Environmental Management Plan helps in formulation, implementation and monitoring of environmental parameters during & commissioning of project. Environment Management Plan (EMP) is the tool to ensure a safe and clean environment. A project may have identified proper mitigation measures but without a management plan to execute it, the desired results may not be obtained. The Environment Management Plan envisages proper implementation of mitigation measures to reduce the adverse impacts arising out of the project activities. Some of the major objectives of the EMP are: Ensure the project implementation with minimal impacts on all environmental components Minimize the impacts on socio- economic indicators of local and adjoining regions Maintain the highest level of readiness for meeting the needs of any deviation in sustainability practices Systematic implementation with adequate manpower, budget and action plan for EMP To demonstrate the effectiveness of EMP workability along with the project proponent’s commitment.

10.8 Storm water management
In developed area like Industrial estate or company premises, impervious surface such as pavements in factory premises prevents precipitation from naturally soaking to the ground, instead of that water runs into storm drains. Managing the quantity and quality of storm water is termed, "Storm water Management." Storm water calculation To assess the worst case scenario for storm water to be received on project plot, the average annual rainfall revived in Raigad District is considered which is 1850 mm (IMD data 2012 -2016).
Thus average rainfall/month = 1850/4 = 462.5 mm (only 4 months of rainy season are considered),accordingly average rainfall/day = 462.5/30 = 15.41 mm/day & average rainfall per hour = 15.41/24 = 0.64 mm/hr. Storm water quantity can be estimated by three methods. 1. SCS Technique: Curve number method of USDA 2. Commercial Software: Storm water management model (SWMM) or STORM 3. Rational Method. In this section of the report rational method has been used to quantify the amount of storm water runoff per hour in the plant premises.

Details of storm water drains present on project plot
Length of storm water drain present on entire project plot = 478.6 m
Width of storm water drain = 0.25 m
Depth of storm water drain = 0.2 m
