(flora and fauna), Socio Economic Conditions are presented in the report and interpreted with
reference to Standards.
The environmental impact of any industry is likely to be seen around 10 km distance. The
baseline data for calculating impact was collected from area of 10km radius keeping the plant in
the centre. The baseline data collection period was March, 2016 to May, 2016. The findings of
the baseline environmental status on land (topography, soil quality, land use pattern),
meteorology (Temperature, Humidity, rainfall, wind speed), air (ambient air quality- PM10,
PM2.5, SO2, NOX), noise level, ecological environment (flora and fauna), socio economic
conditions, are presented in the report and interpreted with reference to environment standards.
PM10
The results reveal that maximum concentration of PM10 at all locations on 24-hourly basis was
observed to be in the range of 83 & 90 µg/m3. The highest 24-hourly concentration was recorded
at sampling location A5. At the same time minimum average 24-hourly concentration was
observed at location A6. The average concentration of PM10 at all locations was observed to be
ranging between 74µg/m3 to 85µg/m3. The high concentration of particulate matter recorded at
project site (A5) may be due to fugitive emissions and vehicular traffic flow in near sampling
location.
PM2.5
The major source of PM2.5 is due to the anthropogenic activities such as combustion of fossil
fuel, fire wood, biomass burning, etc. The maximum 24 hourly concentration of PM2.5 (46
µg/m3) during the study period was recorded at location A1, whereas the minimum 14 µg/m3
concentration was recorded at A6 location which is a remote area. The minimum concentration
indicates that the residential 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. The average 24
hourly concentration of PM2.5 during the study period was computed to be in the range of 20-38
µg/m3.

Executive Summary
Sadekar Enviro Engineers Pvt. Ltd 7
Sulphur dioxide (SO2)
High level of SO2 in ambient air indicates the presence of combustion fossil fuel in the vicinity.
The ambient air monitoring results indicate that the highest average concentration of SO2 is
experienced at the project site, i.e. location A1. High levels concentration of SO2 at A1 can be
attributed to the traffic of vehicles which are diesel driven. The average concentration of SO2
recorded at all the monitoring locations during the study period ranged between 16 & 27 µg/m3
respectively. It should be noted that maximum 24-hourly average concentration was recorded at
location A1 while the lowest can be observed at location A6. The location A6 can be said to be
scarcely populated. Hence low levels of anthropogenic activities and emissions are observed in
the area.
Oxides of Nitrogen (NOX)
The various forms of Nitrogen in NO, NO2 and N2O are collectively called as Oxides of
Nitrogen. The highest value of 24-hourly average of NOX during the monitoring period was
observed at location A1 while the minimum average was recorded at A6. The average
concentrations were in the range of 23 – 40 µg/m3. The maximum 24 hourly value of NOX was
recorded at the monitoring location A1 (49 µg/m3) whereas the minimum concentration of NOx
was recorded at location A6 (15 µg/m3).

industries are in operation surrounding the proposed location. The MIDC area is barren land, no
forest or eco sensitive area or habitation within 5 km radius of the proposed project site.
Monitoring of Additional Parameters:
The monitoring for additional parameters in ambient air namely Ozone, Lead, Ammonia,
Arsenic, Nickel, Volatile Organic Carbon (VOC) & Benzopyrene (a) was conducted within the
project premises (A1 location). The results for these parameters are presented in Table 3.7.
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.
The values of Ground level ozone were estimated to be within the range of 58 to 87g/m3. The
average concentration was computed to be 69 g/m3. The concentration of Ammonia varied
between 64 to 108g/m3. The average concentration of Ammonia was estimated to be 82g/m3.
The concentration of VOC was estimated to be minimal ranging between 8.2 and 20.4 g/m3.
The average for VOC was computed to be 13.6 g/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.
Surface water quality
The results of the surface water analysis are discussed in the section. The values obtained are
compared with the standards prescribed for the respective designated use of the water body as
categorized in the earlier part of the study.
Based on the analysis results of water samples it can be stated that the pH of all the samples was
found to vary between 7.20 – 7.89. It should be noted that the values obtained were within the
desirable limit for pH as prescribed by CPCB. The total hardness was observed to be ranging
between 142.3 to 8542.0 mg/l. The maximum value of hardness was recorded at SW3 which is a
creek water location and the minimum value was recorded at SW4. The concentration of Total

Dissolved Solids was in the range of 198.3 mg/l to 40536.0 mg/l. The maximum concentration of
Total Dissolved Solids (TDS) was observed at SW3 whereas the minimum TDS concentration
was observed at SW4. The large variation observed in the concentration of TDS can be said to be
present since the locations are varied ranging from river water body to lakes and creeks. The
Chemical Oxygen Demand (COD) & Biochemical Oxygen Demand (BOD) values were
calculated to be in the range of <4 mg/l to 248 mg/l & <3 mg/l to 152 mg/l respectively. The
COD values at all the locations were well within the CPCB prescribed standards. The maximum
value of COD was estimated at Uchelli Creek at location SW 6.
The concentration of heavy metals such as Arsenic, Nickel, Mercury and Lead was observed to
be below the detection limit. The metals namely chromium, zinc and iron were found to be
present in trace concentration.
The analysis of microbiological parameters reveals that total coliforms are present at all the
locations in the selected water bodies. The highest number of Total coliforms can be observed at
SW1 which is Arabian Sea, while the lowest number of coliforms can be observed at SW 08
Surya River. The E-coli were found to be present at all locations except at SW 5 and SW8. It
may be possible that the water bodies are subject to discharge of uncontrolled and untreated
domestic waste in the form of sewage and storm water drainages.
The values of nitrate and phosphates also indicate that domestic sewage can be a major source of
pollution in the selected water bodies.
Based on the above results it can be concluded that out of the selected water bodies (sampling
locations) SW1 to SW4, SW6 and SW7 can be classified under category “E” and while locations
SW5 and SW8 can be categorized under the category “B”. In case of the water bodies classified
under the category “E” it can be observed that, the values of all the prescribed parameters were
exceeded at locations SW1, SW2, SW3 and SW6. The parameters were found to be within the
prescribed limits except for SW4 and which have minimal human interference. It is important to

note that the locations SW1, SW2, SW3, SW5 and SW6 are saline water bodies. SW1 is the
Arabian sea, whereas other locations creek or back waters of the Arabian sea and hence
experience the estuarine conditions leading to a mixed aquatic environment. Therefore these
water can be considered fit for control discharges of waste water. The location SW 4 is a
seasonal lake and thus is suitable for designated purpose under the category “E” as per the
standards.
The high load of pollutants at location SW6 can be said due to the discharge of Taloja CETP in
Uchelli Creek.
In the case of location SW5 and SW8 which are categorized under the category “B”, it can be
observed that the permissible limits set under the criteria are not exceeded and hence these water
bodies can be said to be fit for outdoor organized bathing activities.
Ground water quality
Ground Water monitoring was carried out at eight different locations. Most of the sampling was
done from the bore wells located in the near-by villages of the study area. During the baseline
data collection it was observed that in some of the cases the water from the ground water sources
is used for drinking, domestic and irrigation purposes. The results obtained thereby are compared
with the IS 10500:2012standards.
It can be observed that the results indicate that pH ranges in between 7.1 to 7.9, which is well
within the specified standard of 6.5 to 8.5. The maximum pH of 7.9 was observed at Salwad
Village (GW3) and the minimum pH of 7.1 was observed at Umroli village (GW6). Total
hardness was observed to be ranging between 208 to 364 mg/l. The maximum hardness was
recorded at Navapur (GW4) and the minimum hardness (208 mg/l) was estimated at Satpati
Village (GW1). It should be noted that the values of hardness were found to be exceeded the
acceptable limit of limit of IS 10500:2012 standards at all the eight sampling locations but was
found to be under the permissible limit of 600mg/l. The concentrations of Chlorides at all the

locations were estimated to be ranging between 50.6 and 442.7 mg/l. The concentration of
chlorides was observed to be exceeding the acceptable standards but within the permissible limit
at two locations (GW7 and GW8). The amount of Nitrate in the given samples was found to be
in the range of from 1.6 mg/l to 4.9 mg/l.
It should be noted that iron content in all the samples collected was found to be below the
detection limit. The microbiological analysis for the samples revealed that E-coli were absent in
all the locations.
Based on the above analysis it can be concluded that the ground water can be considered for use
for drinking, domestic & irrigation purposes after a basic primary treatment.
Noise Quality
Industrial Zone
The day time noise level at the project premises was observed to be 66.4 dB (A) while during
night time the noise level was recorded to be 60.8 dB (A). It should be noted that the noise levels
during the day time as well as night time can be observed to be under the prescribed standards by
Central Pollution Control Board for Industrial Areas. One of the major reasons for low noise
levels can be the absence of any production, construction or operational activity on the project
site at present.
Residential Zone
The noise monitoring was conducted at representative sites at seven locations for 24hr. As
prescribed the sampling was carried out once in a week and average hourly readings were
recorded. The minimum noise level recorded during the daytime was observed at location N6,
where as the maximum noise levels can be observed at location N5. The high values of noise are
due to the presence of major road which connects Boisar to Palghar in the vicinity of the

Based on the above findings it can be concluded that the soil samples can be classified as per soil
classification given by Hand Book of Agriculture, ICAR, New Delhi and Tondon H.L.S. (2005).
The samples can be said to contain nutrients from average to more than sufficient amount at all
the sampling locations (Table 3.21 and table 3.22).
Biological Environment
The proposed project is located in notified Tarapur MIDC industrial area and the project plot
being devoid of any vegetation any sort of clearing/felling activities will not be involved hence
any sort of habitat loss will not occur. The project does not envisages any liquid or solid
(effluent/hazardous waste) discharge/disposal on the ground or in the water bodies within the
study area since it will be operated as zero liquid discharge until the commission of new CETP &
after which effluent will be disposed to CETP & hazardous waste to be disposed at CHWTSDF,
also any species of conservation concern is not present within the study area & moreover & the
project plot being located well within precincts of MIDC area no adverse impacts are anticipated
on the biotic environment.
Socio-Economic aspects
The data collected by the assessment tool had three variables namely; accessibility of
public resources and its satisfaction, impact of industrial activity of NGL Fine Chem Ltd. and
attitude towards NGL Fine Chem Ltd. The data of 50 participants was put for correlation
analysis. The data was found to be normally distributed hence; the data fulfils the assumptions
of parametric statistics. Based on this information Pearson product-moment correlation was
conducted.
It is found that accessibility of public resources and its satisfaction is significantly correlated in
positive direction with impact of NGL Fine Chem Ltd. industry activity (r = 0.69; p = .01). This
indicates that accessibility of public resources will lead to low impact of industry activities and
vice versa. Accessibility of public resources and its satisfaction is also found to be significantly
correlated with attitude towards NGL Fine Chem Ltd. industry activity (r = -0.53; p = .05) but in

CHAPTER 3: DESCRIPTION OF THE ENVIROMENT
Obtaining environmental clearance is a regulatory norm for any expansion or new industrial
production unit in India. An overview of the process of obtaining environmental clearance from
the regulatory authorities is depicted in the Fig. 3.1. To follow the process a systematic approach
is necessary to be sketched and followed which is termed as Methodology. The methodology
adopted by the consultant organization for availing the said clearance is presented in Fig. 3.2.
As a part of methodology, describing the present status of the environment is an important
function which enables the consultant and the decision makers to predict and minimize the
environmental impacts. The present chapter describes the status of prevailing environmental
conditions in the defined study area. The chapter provides insights on climatic and
meteorological features in around the project site along with air quality, water quality, soil
quality and noise pollution levels. The study also encompasses the ecological biodiversity of the
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. For the purpose of conducting the study duration of three months
is taken into consideration.
The Standard Operating Procedures (SOPs) for the above mentioned functional areas as
applicable in the study are followed from SEE-METH-EIA-02 to SEE-METH-EIA-06 as per the

3.1. Meteorology
Since the meteorological conditions are known to influence the formation and dispersion of
pollutants at local, regional, national as well as global scale, it is important to study the
meteorology of an area before carrying out any assessment of other aspects. Moreover these
meteorological conditions are known to vary spatially and temporally. Thus, it is important to
study the micro-meteorological conditions around the study area in order to estimate their
influence on formation and dispersion of pollutants.
For the present study primary data for meteorological parameters was monitored during the
sampling period (three months) at the site and for reference a secondary data of five years (2011-
2015) was obtained from Indian Meteorological Department (IMD) of Palghar (Dahanu) district.
3.1.1. Secondary Data from IMD
As mentioned earlier the secondary data of meteorological parameters was obtained from the
IMD Palghar (Dahanu) for a period of five years from Jan., 2011 to Dec., 2015. The secondary
data was obtained for Temperature, Barometric Pressure, Relative Humidity, Wind speed, Wind
direction and Precipitation (rainfall). The data for Cloud Cover was compiled from the
climatological tables from the IMD. The monthly average of the temperature, relative humidity,
barometric pressure and rainfall is presented is presented in Table 3.1.
a. Temperature:
On the basis of the data it can be inferred that the study area exhibits characteristics of typical
tropical site having four distinct seasons. The winter season starts during December and it is at
peak in mid January. The minimum temperature drops up to 13.0 C and is mostly experienced
during the night time. The maximum temperature of the season is recorded to be 34.5 C in the
month of December. The season ends in February with the on-set of summer season which lasts
till month of May. During this season maximum temperature was recorded to be 35.9 C whereas
the minimum ambient temperature was observed to be 17.1 C. It is important to note that both
the minima and maxima of temperature are experienced in the same month.

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 lowest in winter season and
highest in the monsoon season. The highest average of relative humidity was observed to be up
to 91.4 % in the month of August.
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 on average 883.9 mm of rainfall is received in the month of
July. In rare cases retreating precipitation from retreating monsoon winds is received in the
month of February.

Sadekar Enviro Engineers . Ltd Chapter 3- 7
d. Atmospheric Pressure:
The change in atmospheric pressure is experienced diurnally and seasonally which coincides
with the change in night and day time temperature. The variation in pressure influences the
vertical mixing of the air and thereby interferes with the vertical as well as horizontal mixing
pollutants present in the atmosphere. 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 July.
e. Wind direction and Wind speed:
The details of the wind direction and wind speed for the five year are presented in Table 3.2.
The distribution of wind pattern for past five years data collected from IMD is presented in Fig.
3.2 and the Windrose presented in Fig 3.3 depicts the wind direction and wind speed during the
specific mentoring duration considered for the present study.
The details of the micro meteorological data collected using the monitoring station installed at
proposed site is discussed in detail in separate section.
Table No 3.2 Wind direction and Wind speed from (Secondary Data)
Interpretation: Similar to the atmospheric pressure, wind speed and wind direction influences
horizontal and vertical dispersion of pollutants. The impact of wind speed and wind direction is
greater than that of atmospheric pressure as wind has the capacity to disperse the pollutant
parcels to local, regional as well as global scale. The windrose for annual & 3 months (March to
May) has been plotted using secondary data obtained from Indian Meteorological Department
(IMD). The Annual plotted wind rose clearly shows that, during five years (from 2011-2015)
predominant wind were blowing from South-East-East direction to North-West direction.

Figure No. 3.3 Annual Windrose from 2011-2015 Figure No. 3.4 Wind rose from 2011 to 2015 (Mar. to May)
Examining the wind from South-East-East direction shows that, around 11% of wind blows from
this direction during the period of five years.
The wind rose prepared for period of five years for month of March to May (summer season) in
Fig. 3.4 clearly represents that the maximum air is blowing from South-West direction during the
summer season.
By observing the strand from South-West direction it is evident that around 25% of wind is
blowing from this direction in summer season during five years (i.e. 2011-2015)
By observing both the Windrose, it can be seen that the predominant wind direction of the region
is South West to North East. The maximum wind speed is also observed in the same 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 March to
May. According to the interpretation of the secondary data for meteorology it is concluded that
the downwind direction is towards the North East.

3.1.2. Site Specific Meteorological Data
In order to determine the prevailing micro-meteorological conditions during the study period, an
automatic weather monitoring station was installed at the project site. The station was installed at
a height of 10 m above the ground level and away from obstructions in the vicinity of the
sensors. The crucial Micro meteorological parameters like wind speed; wind direction, rainfall,
temperature and relative humidity were monitored continuously on hourly basis. The
meteorological data was monitored for a period of 3 months from March 2016 to May 2016. The
summary of the meteorological data is provided in Table 3.3.
TemperatureTemperature during the study period was found to vary from 20.80C to 37.40C during the studyperiod.Relative HumidityThe Relative Humidity during the study period varied in the range of minimum 30% tomaximum 93%Wind Speed and Wind Direction
A review of the composite wind rose diagram for three months March 2016 to May 2016(summer season) as depicted in figure 3.5 shows that prominent wind direction is South – West –to North East. The minimum & maximum wind speeds observed are 0.5 km/hr & 28.6 km/hrrespectively.Table 3.3 Summary of Site Specific Meteorological Data from March to May, 2016

Interpretation: The site specific wind rose has been prepared by using the micro meteorological
data at project site. The wind rose thus obtained pattern in both cases exhibits that the maximum
wind is blowing from South –West. By observing the strands from South –West direction it can
be inferred that, about 29% of total wind was blowing from these directions. Examining the
spoke of South West it can be stated that 15% of wind blowing with the speed higher than 10.6
m/s, 4% of the wind is blowing with the speed between 8.6-10.6m/s, 3% of the wind is blowing
with the speed between 6.6-7.6 m/s & calms wind is 8 % of the total sampling duration.
Comments: The secondary data and the primary data collected from the project site have been
compared and analyzed to verify the quality of the data. The comparison of the secondary (for
five years from Mar to May) meteorological data with the primary data monitored at site is
summarized as under indicates:

Minimal variation in the values is observed in the two data sets. For instance the
minimum temperature recorded at the monitoring site was 20.8 C and the same from the
secondary data was observed to be 17.1 C, while the maximum temperature at project
site was measured to be 37.4 C at the same time the maximum temperature from the
meteorological data from IMD was observed to be 35.7 C.
The data for minimum relative humidity recorded at site was noted to be 30% and that
from secondary was observed to be 30.3%. At the same time maximum relative humidity
recorded at site was 93 % while the same according to the secondary data was 93.3%.
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.

3.2. Ambient Air Quality Monitoring
The baseline data for the proposed project is collected during month of March – May, 2016. As
per the guidelines an area having a radius of 10 Km from project site was considered as the study
area. Air quality monitoring was carried out at selected locations within the study area. The study
area comprises of scattered settlements of Industries, Residential areas & Commercial areas,
small agricultural areas and open/scrub land. It should also be noted that the satellite imagery
indicates presence of salt pans on large scale occupying the northern and southern parts. The
major fresh water body in the study area is Surya River to the extreme east and the Arabian Sea
to the West.
The ambient air quality monitoring was carried out in 10 km radial distance of the project site.
The study area is categorized as an urban area.
Sources of Pollution in the vicinity:
As mentioned earlier since the area is located inside MIDC, the surrounding industries and
their emissions are one of the most important sources of ambient air pollution.
Adjoining to the industrial belt is residential town of Boisar. Along with this, numerous small
towns like Pasthal, Salagaon, Saravali are located in the vicinity. The activities from
residential which are mostly linked with transportation area can be considered as significant
contributors towards air pollution.
The transportation activities other than that of the residential area another major source of air
pollution. A major Highway (Boisar-Palghar Highway) passes from 1.0 k. m. distance of the
site which has high traffic density of heavy vehicles.
3.2.1. Sampling Details
The ambient air quality monitoring network of eight locations as per Standard ToR was designed
after referring to the interpretations related to meteorological analysis of the prominent wind
direction (from secondary and primary sources). The sampling was carried out twice a week as
per the NAAQS Notification of November 2009. At the project site the Ambient Air Quality
Monitoring was carried out for all the 12 parameters for which standards are prescribed by the

3.2.5. Interpretation of Primary Data
PM10
The results reveal that maximum concentration of PM10 at all locations on 24-hourly basis was
observed to be in the range of 83 & 90 µg/m3. The highest 24-hourly concentration was recorded
at sampling location A5. At the same time minimum average 24-hourly concentration was
observed at location A6. The average concentration of PM10 at all locations was observed to be
ranging between 74µg/m3 to 85µg/m3. The high concentration of particulate matter recorded at
project site (A5) may be due to fugitive emissions and vehicular traffic flow in near sampling
location.
PM2.5
The major source of PM2.5 is due to the anthropogenic activities such as combustion of fossil
fuel, fire wood, biomass burning, etc. The maximum 24 hourly concentration of PM2.5 (46
µg/m3) during the study period was recorded at location A1, whereas the minimum 14 µg/m3
concentration was recorded at A6 location which is a remote area. The minimum concentration
indicates that the residential 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. The average 24
hourly concentration of PM2.5 during the study period was computed to be in the range of 20-38
µg/m3.
Sulphur dioxide (SO2)
High level of SO2 in ambient air indicates the presence of combustion fossil fuel in the vicinity.
The ambient air monitoring results indicate that the highest average concentration of SO2 is
experienced at the project site, i.e. location A1. High levels concentration of SO2 at A1 can be
attributed to the traffic of vehicles which are diesel driven. The average concentration of SO2
recorded at all the monitoring locations during the study period ranged between 16 & 27 µg/m3

respectively. It should be noted that maximum 24-hourly average concentration was recorded at
location A1 while the lowest can be observed at location A6. The location A6 can be said to be
scarcely populated. Hence low levels of anthropogenic activities and emissions are observed in
the area.
Oxides of Nitrogen (NOX)
The various forms of Nitrogen in NO, NO2 and N2O are collectively called as Oxides of
Nitrogen. The highest value of 24-hourly average of NOX during the monitoring period was
observed at location A1 while the minimum average was recorded at A6. The average
concentrations were in the range of 23 – 40 µg/m3. The maximum 24 hourly value of NOX was
recorded at the monitoring location A1 (49 µg/m3) whereas the minimum concentration of NOx
was recorded at location A6 (15 µg/m3).
Carbon monoxide (CO)
The anthropogenic source of CO is due to incomplete combustion of fossil fuel (by vehicle
movement) or wood around the given area. The maximum 1 hourly average concentration of CO
estimated at all locations during the study period can be observed to be within 1.5 to 2.6 mg/m3
respectively. The minimum 1 hourly concentration at all locations ranged between 0.6 and 1.4
mg/m3. The highest average is calculated at location A1 and the lowest average was estimated to
be at location A6 at Shirgaon Village.

Monitoring of Additional Parameters:
The monitoring for additional parameters in ambient air namely Ozone, Lead, Ammonia,
Arsenic, Nickel, Volatile Organic Carbon (VOC) & Benzopyrene (a) was conducted within the
project premises (A1 location). The results for these parameters are presented in Table 3.7.
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.
The values of Ground level ozone were estimated to be within the range of 58 to 87g/m3. The
average concentration was computed to be 69 g/m3. The concentration of Ammonia varied
between 64 to 108g/m3. The average concentration of Ammonia was estimated to be 82g/m3.
The concentration of VOC was estimated to be minimal ranging between 8.2 and 20.4 g/m3.
The average for VOC was computed to be 13.6 g/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.

Conclusion: Ambient Air Quality Monitoring was carried out at all the locations in the study
area as per the CPCB guidelines. It was conducted with an aim to understand the prevailing
environmental conditions at the receptor sites as identified by Functional Area Experts from the
reconnaissance surveys, secondary data, published literature and meteorological data. The
analysis and observations indicate that levels of pollutants were found to be within the standards
prescribed by the CPCB except at the project site as well as at other locations. Highest level of
pollution can be observed at location A1 in MIDC at the project site at location A5 (Boisar). It
should be noted that the level of pollution at location A1 and A5 is close and the values have
minimal difference. This can be a result of continuous anthropogenic activities such as industrial
processes, vehicular traffic, etc. A major highway connecting Boisar and Palghar passes near the
sampling site which may be the reason for high concentration of pollutions in the region.
The above findings were verified and compared with authentic secondary data provided
Maharashtra State Pollution Control Board. The data from MPCB also indicates that the levels of
PM10 were high and near to the permissible on multiple occasions at the monitoring stations of
MPCB in the Tarapur MIDC. It is important to note that the readings for PM10 were observed to
remain consistently high during the monitoring period. The observations of statistical analysis
indicate that there is negligible degree of variation in the 98th Percentile values compared to the
maximum values at all the sampling locations. It is important to highlight that the present project
is a Greenfield project.
The results of additional parameters monitored at the project site reveal that the permissible
limits of exposure were not exceeded on any occasion.
The lowest level of pollution is experienced at location A6. The reason for the low
concentrations of pollutants can be said to be its remote location and scarce population.

3.3. Surface Water Quality
3.3.1. Surface water sources in the study area
The study area when observed in satellite images reveals that the area has presence of Arabian
Sea on the Western side as the major Surface Water body. The Arabian Sea is observed to
ingress into the study area in the form of few creeklets and creek. The creeks in the area are
known as Satpati Creek and Dandi Creek. Apart from the salt water body, the major fresh water
body in the area runs on the Far East side of the study area and is known as Surya River. Another
small river known as Banganga River is also reported to be flowing in the study area.
The area has presence of canal which carries water from the Surya River and in from North East
to South West Direction. The canal can be observed to be dry during the summer season.The
river later joins the Arabian Sea on the Western Coast at Virar, Thane Dist. Apart from this the
study area also has presence of few artificial lakes, located within the radius 10km. The lakes
found in the study area are mostly used for recreational purposes. One of the most peculiar
features of the study area is that it has presence of several stagnant water bodies, which are used
as Salt Pans and hence such sites were not considered for sampling. The sampling locations for
the water bodies were finalized after reconnaissance survey and consultation with the functional
area experts from the respective areas.
3.3.2. Probable sources of surface water pollution in the study can be said to be:
The Surya River Stretch in the study area is originating in the hilly area of Kawadas. On
its way it is expected to be subjected to run-offs from agricultural fields and orchards which use
chemical fertilizers for plantations. Also on certain occasions in the study area the river is also
subjected to domestic discharges from the surrounding residential areas.
3.3.3. Sampling Methodology
a. Criteria for Selection of sampling locations
The locations were selected by the respective FAEs after considering the following points-

1. The sampling locations were selected based on upstream and downstream uses of the
water body.
2. Drainage Pattern.
3. Mouth of local/MIDC drains into the river.
4. Lake/Dam in the study area.5. Water bodies which may be affected due to the proposed activity.
Based on the above understanding the selected sampling locations are presented on Google Earth
Imagery in Fig. 3.8. A total of eight sampling locations were selected for the present study. The
details of sampling locations are provided in Table 3.8.The list of parameters assessed and the
methodologies for analysis of water samples are presented in Table 3.9. The method detection
limits are also provided in the table with respective units of measurement.
3.3.4. Sampling Details
Grab samples were collected from the identified surface water bodies located in the study area.
The sampling frequency was once during the sampling period of the proposed project (study
period – March to May, 2016).
3.3.5. Sample Collection, Preservation and Transportation:
Sampling was carried out by trained personnel with relevant experience and knowledge of
sampling. It is also important to note that care should be taken that the samples are not altered
significantly in their condition and are in a state acceptable for analysis at the laboratory. Hence,
it is vital that all the procedures are followed during the process of sample transport and storage
in order to ensure homogeneity of the samples.
The key aspects which were focused during transport and storage are highlighted as under:
• Samples were collected in HDPE containers and packed to avoid breakage and cross-
contamination.
• Sample degradation was reduced through appropriate preservation and 1ml 1N HNO3 per
liter of sample was added for analysis of selected metals.

3.3.6. Interpretation
The results of the surface water analysis are discussed in the section. The values obtained are
compared with the standards prescribed for the respective designated use of the water body as
categorized in the earlier part of the study.
Based on the analysis results of water samples it can be stated that the pH of all the samples was
found to vary between 7.20 – 7.89. It should be noted that the values obtained were within the
desirable limit for pH as prescribed by CPCB. The total hardness was observed to be ranging between
142.3 to 8542.0 mg/l. The maximum value of hardness was recorded at SW3 which is a creek water
location and the minimum value was recorded at SW4. The concentration of Total Dissolved Solids
was in the range of 198.3 mg/l to 40536.0 mg/l. The maximum concentration of Total Dissolved
Solids (TDS) was observed at SW3 whereas the minimum TDS concentration was observed at SW4.
The large variation observed in the concentration of TDS can be said to be present since the locations
are varied ranging from river water body to lakes and creeks. The Chemical Oxygen Demand (COD)
& Biochemical Oxygen Demand (BOD) values were calculated to be in the range of <4 mg/l to 248
mg/l & <3 mg/l to 152 mg/l respectively. The COD values at all the locations were well within the
CPCB prescribed standards. The maximum value of COD was estimated at Uchelli Creek at location
SW 6.
The concentration of heavy metals such as Arsenic, Nickel, Mercury and Lead was observed to be
below the detection limit. The metals namely chromium, zinc and iron were found to be present in
trace concentration.
The analysis of microbiological parameters reveals that total coliforms are present at all the locations
in the selected water bodies. The highest number of Total coliforms can be observed at SW1 which is
Arabian Sea, while the lowest number of coliforms can be observed at SW 08 Surya River. The E-
coli were found to be present at all locations except at SW 5 and SW8. It may be possible that the

water bodies are subject to discharge of uncontrolled and untreated domestic waste in the form of
sewage and storm water drainages.
The values of nitrate and phosphates also indicate that domestic sewage can be a major source of
pollution in the selected water bodies.
Based on the above results it can be concluded that out of the selected water bodies (sampling
locations) SW1 to SW4, SW6 and SW7 can be classified under category “E” and while locations
SW5 and SW8 can be categorized under the category “B”. In case of the water bodies classified
under the category “E” it can be observed that, the values of all the prescribed parameters were
exceeded at locations SW1, SW2, SW3 and SW6. The parameters were found to be within the
prescribed limits except for SW4 and which have minimal human interference. It is important to note
that the locations SW1, SW2, SW3, SW5 and SW6 are saline water bodies. SW1 is the Arabian sea,
whereas other locations creek or back waters of the Arabian sea and hence experience the estuarine
conditions leading to a mixed aquatic environment. Therefore these water can be considered fit for
control discharges of waste water. The location SW 4 is a seasonal lake and thus is suitable for
designated purpose under the category “E” as per the standards.
The high load of pollutants at location SW6 can be said due to the discharge of Taloja CETP in
Uchelli Creek.
In the case of location SW5 and SW8 which are categorized under the category “B”, it can be
observed that the permissible limits set under the criteria are not exceeded and hence these water
bodies can be said to be fit for outdoor organized bathing activities.

Based on the above results and inferences it can be stated that the water from the above water bodies
can be said to be fit for their designated purpose under the “B and E” category as compared to the
permissible limits provided therein for the Inland Surface Water Standards.

3.4. Ground Water Quality
3.4.1. Ground water sources in the study area
Although, fresh water is supplied by the pipeline in the areas of Tarapur and Boisar city, ground
water is used as an alternate source in surrounding villages for drinking and domestic purposes.
Therefore it is important to assess the existing baseline status of the ground water quality.
3.4.2. Probable sources of ground water pollution in the study area
The major factors that can affect the ground water quality in the study area can be said to be
uncontrolled discharge of treated and/or untreated industrial effluent, open discharge of treated
and/or untreated sewerage. Apart from the above ground water can be polluted by other activities
such as use of excessive chemical fertilizers in farming, leaching from landfills having toxic or
municipal solid waste, leakage of waste disposal pipelines of CETPs and STPs, etc.
3.4.3. Sampling Details
The section discusses regarding the sampling related procedures, methodologies and parameters
selected for analysis. The section also highlights the criteria adopted for selection of ground
water sampling locations.
The selected sampling locations and their coordinates are presented in Table 3.12.

As suggested by the FAE and the guidelines provided in the Standard ToR, sampling was
decided to be carried out at 8 locations. 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 – March to May, 2016). The details of the
methodology for ground water sampling are provided in Table No. 3.13.
3.4.4. Selection criteria for water quality sampling locations
The sampling sites were selected considering after conducting a reconnaissance survey. While
conducting the survey followings points were considered for finalization of sampling locations -
1. Drainage Pattern.
2. Areas which may be affected due to the proposed 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.
5. Feasibility and accessibility to the sampling locations
Apart from this 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 Google Earth Imagery in Fig. 3.8.
The results for analysis conducted are presented in Table 3.14. These results are compared
with the drinking water standards provided by IS (Table 3.15).
The aspects related to Sample Collection, Preservation and Transportation are described in
detail in the above section 3.3.5.

3.4.5. Interpretation:
Ground Water monitoring was carried out at eight different locations. Most of the sampling was
done from the bore wells located in the near-by villages of the study area. During the baseline
data collection it was observed that in some of the cases the water from the ground water sources
is used for drinking, domestic and irrigation purposes. The results obtained thereby are compared
with the IS 10500:2012standards.
It can be observed that the results indicate that pH ranges in between 7.1 to 7.9, which is well
within the specified standard of 6.5 to 8.5. The maximum pH of 7.9 was observed at Salwad
Village (GW3) and the minimum pH of 7.1 was observed at Umroli village (GW6). Total

hardness was observed to be ranging between 208 to 364 mg/l. The maximum hardness was
recorded at Navapur (GW4) and the minimum hardness (208 mg/l) was estimated at Satpati
Village (GW1). It should be noted that the values of hardness were found to be exceeded the
acceptable limit of limit of IS 10500:2012 standards at all the eight sampling locations but was
found to be under the permissible limit of 600mg/l. The concentrations of Chlorides at all the
locations were estimated to be ranging between 50.6 and 442.7 mg/l. The concentration of
chlorides was observed to be exceeding the acceptable standards but within the permissible limit
at two locations (GW7 and GW8). The amount of Nitrate in the given samples was found to be
in the range of from 1.6 mg/l to 4.9 mg/l.
It should be noted that iron content in all the samples collected was found to be below the
detection limit. The microbiological analysis for the samples revealed that E-coli were absent in
all the locations.
Based on the above analysis it can be concluded that the ground water can be considered for use
for drinking, domestic & irrigation purposes after a basic primary treatment.

3.5. Noise Level Monitoring
Due to increasing anthropogenic activities and development Noise level pollution has become a
topic of concern in the rural as well as urban areas. Noise pollution has various short term and
long term health impacts based on the exposure of individuals. Studies have linked prolonged or
continuous exposure to noise levels with deleterious effects on the humans, plants and animals.
Therefore the Central Pollution Control Board has issued permissible limits for noise level
depending upon the area. The noise level monitoring data can be considered as a baseline data
for a given area. Noise levels monitored help in deciding the control strategies for abatement of
noise pollution.
3.5.1. Probable sources for Noise generation in the study area
As reported earlier the project site is located in the notified industrial area; therefore it is likely
that the primary sources of noise generation around the project site will occur to due various
from the surrounding industrial units in the area. These activities include vehicular movement,
operation of industrial equipment and machinery, construction and demolition, etc. Other sources
of noise pollution in the study area can be said to be anthropogenic activities such as
construction, demolition, repairing, use of loudspeakers, fire crackers, etc.
3.5.2. Monitoring Details
Noise monitoring was carried out as per the Central Pollution Control Board guidelines 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 Image. 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.

The location A1 is situated in the industrial area while rest of the locations can be categorized
into residential areas. The standards used for comparison of the noise levels are therefore used as
per the standards prescribed regulations of CPCB.
3.5.3. Criteria for selection of noise level monitoring locations
The locations for 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 proposed activity.
4. Topography of the study area.
5. Site feasibility related to accessibility, etc.
The details of the monitoring locations are provided in Table 3.16.

3.5.4. Interpretation
Industrial Zone
The day time noise level at the project premises was observed to be 66.4 dB (A) while during
night time the noise level was recorded to be 60.8 dB (A). It should be noted that the noise levels
during the day time as well as night time can be observed to be under the prescribed standards by
Central Pollution Control Board for Industrial Areas. One of the major reasons for low noise
levels can be the absence of any production, construction or operational activity on the project
site at present.
Residential Zone
The noise monitoring was conducted at representative sites at seven locations for 24hr. As
prescribed the sampling was carried out once in a week and average hourly readings were
recorded. The minimum noise level recorded during the daytime was observed at location N6,
where as the maximum noise levels can be observed at location N5. The high values of noise are
due to the presence of major road which connects Boisar to Palghar in the vicinity of the
sampling location. It should be noted that the permissible limits for noise did not exceed at any
of the locations selected for sampling.

3.6. Soil Quality
3.6.1. Probable sources of soil pollution/contamination in the study area
Soil can be said to be polluted due to the discharge of treated or un-treated effluent,
hazardous waste generated, solid waste by various industries located in the industrial cluster. If
the industrial wastes are not disposed off scientifically they may leach into soil and affect the soil
quality adversely. This problem can also arise by uncontrolled disposal of municipal solid waste
or sewage inhabited or vacated land.
3.6.2. Sampling Techniques:
The soil samples were collected from 1.5 m depth
The samples were stored in 1Kg. HDPE zip-lock bags and transported to laboratory in
cool and dry containers.
The samples were analyzed for physical & chemical characteristics. The samples have been
analyzed as per the established methods for physico-chemical parameters & heavy metals.
3.6.3. Sampling Details
The sampling frequency was once a season (study period March to May, 2016) and
samples were collected from five locations.
3.6.4. Criteria for selection of soil sampling location
The locations for collection of representative sample were selected considering -
1. From agricultural land in downwind direction
2. From comparatively polluted site viz. within industrial area
Based on the above understanding five sampling locations were identified for the purpose of
sampling is presented in Fig. 3.10 on Google Earth Image. The coordinates of the sampling
locations are provided in Table 3.18.

3.6.5. Interpretation
The findings of the study reveal that pH of the soil in the study area ranged between 7.1 to 7.8.
This is indicative of the neutral to slightly alkaline nature of soil. The values for Nitrogen at all
locations varied between 276.9 to 460.2 Kg/ha. Maximum concentration of nitrogen was
observed at location S2.
The concentration of phosphate was estimated to be between 79.2 to 135.2 Kg/ha. The highest
concentration can be observed at location S5, while the lowest concentration can be observed at
location S3. It is important to note that the concentration of potassium was found to be ranging
between 230.1 to 643.5 Kg/ha. The presence of heavy metals like arsenic, cadmium, lead &
chromium in all the soil samples were below the detection limit.
Based on the above findings it can be concluded that the soil samples can be classified as per soil
classification given by Hand Book of Agriculture, ICAR, New Delhi and Tondon H.L.S. (2005).
The samples can be said to contain nutrients from average to more than sufficient amount at all
the sampling locations (Table 3.21 and table 3.22).

3.7. Geology & Hydrogeology of the study area
The geological & hydrogeology aspects are often associated with larger areas hence the
geomorphologic aspects of entire Palghar District are considered as described below.
3.7.1. Geology of Palgar District
A major part of district is covered with basalt lava flows generally called as Deccan trap (Fig.
3.12). This volcanic activity was confined mainly to Upper Cretaceous to Lower Eocene age.
Besides Deccan traps, the formation like local alluvium, beach sand, coastal alluvium,
laterites, trachytes & rhyolite cover very small area of the district. The main topographic
features of this lava flows are flat topped hills and steps like terrace Statigraphic sequences
of the geological formation in the district is shown as below:-
Table No. 3.3.22: Statigraphic sequences of geological formation in Palghar District
Formation Age LithologyAlluvium Recent clay, silt and sand
Beach sand Recent sand and siltLaterite Pleistocene LateriteDykes --------- Basic intrusion
Deccan traps basalt Eocene to upper cretaceous AmygdularbasaltRhyolite Eocene to upper cretaceous RhyoliteTrachyte Eocene to upper cretaceous Trachyte
Deccan Traps: The Deccan trap has been divided into three major groups, i.e. upper, middle
and lower. The Bombay basalt flows have been grouped into upper traps on the basis of the
inter-trappean and ash beds present in them. Being in the contiguous area, the Deccan traps in
the district can also be grouped with the upper flows. There are number of dykes criss-
crossing the area. The general trend is however, north-northwest south-southeast and north-
northeast south-southwest, dipping steeply to the east. The thickness seldom exceeds six
meters. The dykes send out offshoots of different sizes, at places enclosing lenticular wedges
of country rock. Chilled margins are seen along dykes flow contact. The dykes vary from
coarse dolerite to fine grained basalts. Most of the dykes are porphyritic of feldspars.
Laterite: Few high basalt plateaus of the district are capped by laterites. These are

hills. The Kanheri and Tungar laterites have conspicuous development of bauxite.
Shore Sands: The sea coast of the district stretching several kilometers along the western
boundary is covered by sands.

Figure No. 3.12: Ground Water Level Source: Groundwater Survey & Development Agency
Hydrogeology of Palghar District
Hydro geologically the basaltic terrain has aquifers in the form of jointed and fractured trap
(Fig. 3.12). The occurrence of ground water in Deccan trap is governed by its degree of
weathering, concentration of joints & fractures planes, porosity & permeability of geological
units. The movement & storage of ground water are mainly controlled by physical &
geological set up of the terrain. The lava flows have no primary porosity. Only after
weathering the cracks develop which allow ground water to store. However due to adverse
morphological conditions, the availability of ground water is mainly restricted to plains &
valley fill. The irrigation based on ground water is seen only in the parts of Dahanu, Talasari,
Vasai, & Palghar Tahsils. The irrigation is mainly of horticultural crops. The coastal sandy
aquifers are sufficiently good yielding, but even a marginal over exploitation causes intrusion
of saline water.

Interpretation
It can be observed that high vehicular density is observed at TS2 as compared to TS 1. The
reason behind such a finding is that TS2 is the point of entry for the MIDC from NH8 which
connects Maharashtra Gujarat and States. Thus it experiences vehicular traffic from both the
directions. The lowest traffic in terms of PCUS is observed near TS1 which is situated inside
the MIDC premises near to the project site. Minimum traffic density was observed near TS1
during evening as well as morning peak hours.
3.8.9.1. Increased traffic scenario due to proposed project
As mentioned earlier the project site is going to be a new establishment and hence addition of
vehicles is unavoidable. The proposed project intends to engage trucks/tempos for the
purpose of transportation of raw materials as well as finished goods. Along with this the
vehicles from the employees are also expected to increase. It is estimated that the proposed
activity will lead to addition 4 trucks/tempos per day to the project site.

SEEPL/EIA/F/IND/NGLFCL/002/2016-17/00CHAPTER NO 3: Description of Environment
Sadekar Enviro Engineers . Ltd Chapter 3- 61
The transportation activity will mainly take place by Boisar-Palghar Road from which further
access to MIDC will be achieved. It should be noted that the same route will be utilized for
exit as alternative route is not available at present.
Along with the transport of raw materials and finished products the number of vehicles used
by the employees, visitors and owners is also expected to increase. This is increase is
accounted up to 50 vehicles in total considering all the vehicular types.
As an initiative for efficient traffic management the project proponent will ensure that
transportation activity will be carried out mainly after 10 a.m. in order to avoid peak hour
traffic. However to assess the increased traffic scenario due to the proposed project the
increased fleet vehicles has been considered. It is estimated that due to the proposed project
the increase in traffic would be 109 PCUs. The present road conditions are sufficient and
effective to carry the increased load of traffic.
The estimated load of PCUs at the traffic monitoring stations is considered and the increased
load of traffic is presented in the Table 3.26 below.

3.9. Land use Pattern
The prevailing Land Use & Land Cover (LULC) pattern in the 10 km radial study area are
assessed based on remote sensing technique using satellite imagery.
The interpretation of satellite image was done in succession stages as described below:
i) Visual Interpretation:
The land use/ land cover classes were established by processing the satellite imagery by using
image processing software to obtain various land use land cover classless & analyzing the
resultant output based on image characteristics/elements such as Color, Tone, Texture,
Pattern, Size, Shape, Association etc.
ii) Ground Truth Survey
Ground truth verification of the doubtful elements/classes encountered during the visual
analysis & interpretations were confirmed by deploying ground truth survey & the findings of
the same were incorporated during finalizing the LULC map of the study area. The LULC
map of the study area is shown in the following figure.

Scope of the study
To assess the implications of the proposed project on the surrounding ecology within study
area following attributes were considered & executed:
To identify & assess habitat loss if any due to the proposed project.
Negative impacts if any on the existing ecologically sensitive areas/potential habitatsin the study area due to the proposed project.
3.10.2 Primary Baseline Data
General features of the prevailing terrestrial ecosystem in study area
The study area viz. Tarapur MIDC industrial area & surrounding 10 km radial study area
comes under the Palghar District. The 10 km radial study area is a part of the coastal plains
on the west coast of India.
As observed during the reconnaissance the inner 5 km (core) radial study area was subjected
to multiple land use forms such as industrial area, human habitations with associated
commercial establishments, small scale salt panning activities & subsistence farming.
However inner 5 km radail study area was characterized presence of wetlands & mangorve
vegetation along the Navapur & Murbe Creeks.
The outer 5 km (buffer) radial is moreover a scrubland with somewhat prominent vegetation
along the hillocks at Gundale, Padghe & Devkhope villages. The observed vegetation stature
in and around these hillocks was of semi evergreen deciduous secondary forest formations.
The remaining major part of the study area was characterized by natural presence of uneven
sporadic patches of scrub, gregarious vegetation & clusters of trees. Also in and around the
human inhabited pockets in the study area, by virtue of plantations & green developmental
activities, orchards & avenue plantations etc. were seen.

3.10.4 Floral diversity & status in the study area
The field studies conducted in the inner 5 km radial study area in and around the the MIDC
area and the wetlands/ marshes along the Navapur & Murbe Creeks reuslted in recording 51
floral species comprising of 24 trees, 6 shrubs, 10 climbers and 11 herbs. As a virtue of
green belt developmental activities in and around the industrial area though the tree diversity
was more, the vegetation stature observed in the core study area was mostly of scurb
dominant flora such as Chromolena, Hyptis, Lantana, Alternanthera, Amaranthus etc. and 4
species of true mangrove were also observed.
Whereas the studies conducted in and around the hillocks at Gundale, Padghe & Devkhope
villages in the bufer study area resulted in recording 65 plant species which comprised of 46
trees, 4 shrubs, 3 climbers and 7 herbs. The vegetation stature observed here was of Southern

with the locals during the EB study.
Reference I - Interactions held with the locals during EB Study
Interactions with locals were held to know the presence/activity of any other wild fauna all
year around. The interactions revealed that locals were largely unaware of presence of any
wild animals. However they had inconsistent sightings of some reptiles and mammal, on the
basis of description provided by them presence of 3 snakes viz. Rat snake, Russel’s viper,
Saw scaled viper and 1 mammal viz. Black naped hare could be concluded as given in Table
No. 6 of the Annexure 3.1.
3.10.10 Applicability of forest & wild life related clearances

Correlation analysis & interpretation:
The data collected by the assessment tool had three variables namely; accessibility of
public resources and its satisfaction, impact of industrial activity of NGL Fine Chem Ltd. and
attitude towards NGL Fine Chem Ltd. The data of 50 participants was put for correlation
analysis. The data was found to be normally distributed hence; the data fulfils the
assumptions of parametric statistics. Based on this information Pearson product-moment
correlation was conducted.
It is found that accessibility of public resources and its satisfaction is significantly
correlated in positive direction with impact of NGL Fine Chem Ltd. industry activity (r =
0.69; p = .01). This indicates that accessibility of public resources will lead to low impact of
industry activities and vice versa. Accessibility of public resources and its satisfaction is also
found to be significantly correlated with attitude towards NGL Fine Chem Ltd. industry
activity (r = -0.53; p = .05) but in negative direction. This indicates that accessibility of public
resources has positive inclination for NGL Fine Chem Ltd. in the study area. Further, it is

CHAPTER 4: ANTICIPATED ENVIRONMENTALIMPACTS & MITIGATION MEASURES
Classifying the sources, estimating the quantity of pollutant, impact of pollution & mitigating
them is the most important component in the Environmental Impact Assessment process. This
chapter quantifies the environmental impacts of various project related activities on various
receptors of environment.
The predictions estimated are superimposed on the baseline value for achieving the resultant
value which signifies the overall impact. It also suggests the various mitigation measures which
can be advocated to minimize the adverse impacts of the project activity.
4.1 Air Environment
4.1.1 Construction Phase:
4.1.1.1 Identification of Source
During construction activities like site clearance, wind erosion, stockpiling & material handling
dust nuisance is the major sources of air pollution. Dust emission while transportation and
leveling of earth is anticipated. SO2 & NOx will be emitted from the diesel powered mechanical
equipment and vehicles. However the number of such equipments will be limited. It is therefore
not accepted to cause an excedance to the NAAQ limit for these gases.
4.1.1.2 Predicted Impact
Dust emissions generally differ from day to day, depending on the level of activity, the specific
operation and the prevailing meteorological conditions. Therefore for predicting the quantitative
value of TSPM that would be generated due to the construction activity an emission factor from
AP-42 Section 13.2.3.1 (U.S.EPA,1995) has been used. The emission factor is E = 1.2
tons/acre/month of activity. The mentioned value is most applicable to construction operations
with a) medium activity level, b) moderate silt contents and 3) semi-arid climate.

The Total plot area of the project is 9174.60 sq. m. The construction work will be carried out
only in that part which is allotted for built up purpose i.e., 2295 sq. m. The construction activity
will not take place simultaneously on the entire allotted plot. Also, the construction activity is
assumed to be carried out for all 30 days of the month (24 Hours). Hence, the estimated value
will be conservatively high for TSPM for worst case scenario. The emission would be around
0.67 tons/month of the activity. But the emission would be reduced to around 90 to 95 % as
control measures will be adopted. There would be around 15-20 temporary workers appointed
for construction activity who may be affected by the dust pollution. Workers getting exposed to
the dust generated due to the construction activity can suffer from respiratory problems and
prolonged exposure to dusty environment can lead to malfunctioning of lungs. It is a temporary
impact occurring during earth moving activities only and will be confined to the construction
area. The effect of air pollution outside the plant boundary is not envisaged. Proper maintenance
of vehicles, sprinkling of water on construction site, providing sufficient green belt etc. are some
of the control measures suggested to reduce the impacts during the construction phase.
4.1.1.3 Mitigation Measures
Control measures like temporary wind barrier, proper traffic management during loading and
unloading of the construction materials, regular sprinkling of water on the working site,
Avoiding Cement dust emission, Managing stockpiles (sand, gravel) by using water sprays
(when emptying cement bags into mixer) will be implemented to ensure minimum dust
generation.
4.1.2 Operational phase:
4.1.2.1 Identification of Sources
Boiler, thermic fluid heater & D.G set are identified as the point sources of air pollution in the
present study. D.G Set of 1MW is proposed. The D.G Sets will only be operational during power
failure.
Other air pollution sources which have been installed are the scrubbers connected to the reactors
to absorb the gases evolved out of reaction or unreacted gases.

Fugitive emission generates due to handling and storage of the solvents in the company premises
as well as possible leakages from reactor unit. The vehicle used for transporting materials also
contributes to the formation of fugitive emission to a much lesser extent
4.1.2.2 Prediction of Impacts
For obtaining the quantitative predicted value of impacts, modeling of air environment is
performed. The criteria pollutants like PM10, PM2.5, SO2, CO & NOx from boilers were
considered for air modeling. D G sets are not considered for impact prediction as they will be
used only during power failure.
Aermod 8.2 developed by USEPA and authorized by CPCB is used for air modeling simulation
which is based on the steady state Gaussian plume equation.
The incremental values at various monitoring were calculated and integrated with the baseline
value for PM10, PM2.5, SO2, NOx & CO The chart is tabulated below-
4.1.2.2.1 Model Options Used for Computation
The plume rise is estimated by Briggs formulae, but the final rise is always limited to that
of the mixing layer;
Stack tip down-wash is not considered;
Point Source Modeling is considered;
Calms processing routine is used by default;
Wind profile exponents is used by default;
Flat terrain is used for computations;
It is assumed that the pollutants do not undergo any physico-chemical transformation and
that there is no pollutant removal by dry deposition;
Washout by rain is not considered; and
Cartesian co-ordinate system has been used for computations.

4.1.2.2.2 Modeling Procedure
The prediction of the Ground Level Concentrations (GLC’s) due to activity has been computed
by AERMOD version 8.2 as per CPCB guidelines. While performing the model the rural
dispersion and regulatory defaults options were selected as per guidelines on air quality models
(PROBES/70/1997-1998).
4.1.2.2.3 Meteorological Data Processing
The surface synoptic meteorological data of Thane District for the year 2011-2015 were
obtained from the Indian Meteorological Department, Mumbai. The meteorological
observation station of IMD for Palghar District is located at Dahanu (Station Index: 43001,
anemometer height of 10 m). The quality assurance process was undertaken as required by the
EPA (EPA-454/R-99-005) to identify and fill the missing data for preparation of hourly surface
meteorological data. The surface and profile met data were prepared for use in AERMOD
using the AERMET meteorological data preprocessor of Lakes Environmental. Processing the
surface file indicated more than 90 % data availability. Onsite meteorological data collected for
three months were used to process the AERMET file and not the upper air meteorological data.
Meteorological inputs required are hourly wind speed and direction, ambient temperature,
pressure, precipitation, cloud cover, stability class and mixing height.
The atmospheric inversion level at Thane for 12 hours from 7:00 hour to 7:00 hour is
represented in the below table No 4.1. The data has been compiled from IMD manual.

The total workers in the factory premises will be around 150 who may be affected due to the
unscientific operation of boiler & thermic fluid heater. Mostly the health effects associated with
particulate matter are respiratory, pulmonary injury, lung cancer etc. Exposure to SO2 and NOx
also lead to respiratory problems. Carbon monoxide decreases the oxygen carrying capacity of
blood by reducing the hemoglobin. Since the company is handling some highly volatile solvents
the VOC emission can have an adverse affect on the workers health if present in higher
concentration. The health effects related to VOC emission are eye, nose and throat irritation
headaches, loss of coordination and nausea, damage to liver, kidney and central nervous system
etc.
The air emissions in long course of time may affect the immediate surrounding vegetation stature
physically (leaf senescence, hampered growth etc.) & biologically thus may affect the overall
surrounding ecology.
The incremental values at various monitoring stations were predicted and integrated with the
baseline value for PM10, PM 2.5, SO2, NOx & CO is tabulated in the below table no 4.3. The

Interpretation
The incremental value of the specific pollutant at the particular monitoring station is added to the
baseline value of that specific pollutant measured during the monitoring period of the project.
The resultant value thus calculated used for predicting the impacts of the project on the air
environment in the study area.
4.1.2.2.5 Impact of transport of raw materials and end products on the surroundingenvironment.
In most cases, transport of raw materials, general supplies and final products causes an increase
in traffic around the facility. Nearly 3-4 trucks per day would be used for transportation of raw
materials and final product. Transportation and environment are paradoxical in nature. As the
transportation conveys substantial socioeconomic benefits, but at the same time transportation is
impacting environmental systems.
4.1.2.3 Mitigation Measures
The prominent pollutants like PM10, PM2.5, SO2 , NOx & CO will be generated due to the fuel
combustion for operation of units like Boiler, thermopack & D.G Set. The mitigation measure
that will be adopted is providing an appropriate stack height for dispersion of pollutants. The
stack height calculation is shown below,

consumption = 250 kg/hr coal (5000 kg/ day). The Sulphur content of coal is near to 1% Hence
250 kg coal will contain 2.50 kg Sulphur Now stoichiometric conversion of Sulphur to SO2 = 2.5
X 2 = 5.0 kg
Thermic fluid heater: 300 kg/day FO
i.e. 16.67kg/hr (@ 18 hours of working)
The Sulphur content of FO is 4.5%
Hence 16.67 kg FO will contain 0.75 kg Sulphur
Now stoichiometric conversion of Sulphur to SO2= 0.75 X 2 = 1.5 kg
Therefore, total SO2 will be,
5.0+1.5 = 6.5 kg/hr.
The effective height of the stack will be equal to,

Bag filter:
Filtration, using cloth filter as media is one of
the most reliable, efficient and economic
methods by which particulate matter can be
removed from gaseous streams. A bag filter
consists of numerous vertical bags of 120 to
400 mm diameter and 2 to 10 m long. They
are suspended with open ends attached to a
manifold. The hopper at the bottom serves as
a collector for the dust. The gas entering
through the inlet duct strikes a baffle plate,
which causes the larger particles to fall due to
gravity. The carrier gas then flows to the tubes
and then outward through the fabric leaving
the particulate matter as a cake on the bag
surface. Ash content in Indian coal is high and Fig. 4.1: General arrangement of bag filter
typical concentration of particulate matter at the inlet of air pollution control equipment is 30 to
80 g/Nm3.
(Source: Report-Assessment of requirement of Bag filter vis a vis Electrostatic Precipitator in Thermal PowerPlants, A report by CPCB, March 2007)
M/s NGL Fine Chem Ltd. will install a bag filter with design efficiency of 99.9 % removal of
particulate matter and bring down the concentration of PM below 100 mg/m3. To achieve stated
outlet concentration following design criterion will be adopted. The outlet concentration of
particulate matter from bag filter is explained in annexure 4.3

For dealing with the process emissions i.e. the acidic &
gases from the manufacturing process two acidic scrubbers
will be installed. Packed bed scrubbers will be double stage
scrubber and will have capacity 200 CFM each, are
sufficient to mitigate the emissions due to proposed
production activity. Certain measures can be established to
reduce the VOC emission in the plant premises like carbon
adsorption systems, to prepare and follow chemical charging
SOP, operation and maintenance controls as leak prevention
etc. Control measures for dust emission control. The
following measures will be adopted for controlling the dust
emission,
The roads within the premises shall be sprinkled with
Water at a regular interval to avoid the dust generation.
To be ensured that all transportation vehicles carry a valid PUC (Pollution under Control)
Certificate.
Proper servicing & maintenance of vehicles is being carried out.
Adequate green belt >33% of total open area as per MPCB shall be developed in the project
plot. Green belt act as surface for settling of dust particle and thus will reduce the particulate
matter in air.
Ambient air quality shall be regularly monitored to ensure the air pollution devices are
working efficiently.
From the above, it can be concluded that after the operation of the project and implementation of
mitigation measures in an appropriate manner, the Ambient Air Quality will not exceed NAAQ
Standards.

4.2 Water Environment
4.2.1 Construction phase
4.2.1.1 Probable Sources:
The project is not surrounded by any of the major water bodies within 1-2 km radius of the
project. The potential source of impact to water quality from the construction phase could
include the following activities,
Construction runoff and drainage including dewatering operations: Potentials sources
would be wash water from dust suppression sprays, wheel washing facilities, runoff and
erosion from the site surfaces & stockpiles and fuel oil & lubricants from the maintenance of
construction vehicles and equipments.
Runoff from general construction activities: The construction activity like foundation
lying & concrete mixing etc, involve high amount of water consumption. The source of water
supply would be from Tarapur MIDC. The runoff can be caused due to the improper
handling of the construction equipment.
Sewage effluents generated from the construction workforce: Around 15-20 numbers of
temporary workers will be engaged for the construction activity. According to the NBC
(National Building Code of India) 45 lit/d/person is considered for domestic water
consumption i.e. 0.9 CMD. Sewage effluent will be generated by the on-site construction
workforce these have the potential to cause water pollution if not controlled.
4.2.1.2 Impact predicted
Runoff from construction area may contain increased loads of suspended solids (SS) and
contaminants. The sewage wastewater is characterized by high level of biochemical oxygen
demand, ammonia & E-coli counts. Therefore exposure of such runoffs to the water bodies will
have a significant negative impact on the water quality. Septic tank will be provided for
treatment for sewage treatment and treated water will be released to sewers. Hence minimal
impact is envisaged on the prevailing water quality in the study area.

Sadekar Enviro Engineers Pvt. Ltd Chapter 4- 14
4.2.1.3 Proposed Mitigation
It is important that appropriate measures are implemented to control the runoff & drainage water
from entering the nearby water courses.
Construction runoff and drainage: As the company will construct storm water drainage
of adequate capacity for controlled release of storm flows. Proper site management is
essential to minimize the surface water runoff & soil erosion. Good housekeeping will be
practiced like handling & disposing of solid waste i.e. debris & rubbish to enter from the
drainage column.
Sewage effluents generated from the construction workforce: to treat the domestic
sewage septic tank will be used the treated sewage will be disposed to MIDC sewerage
system.
4.2.2 Operational Phase
4.2.2.1 Probable Source
During the project in operational phase, wastewater generation will be through multiple sources
such as manufacturing process, scrubbers, domestic activities & utilities. The water supply
demand will be met through Tarapur MIDC water supply.
The effluent generated will be segregated into two broad streams i.e. High COD/TDS streams
generated from the manufacturing process & scrubber effluent & Low COD/TDS streams from
blow down water from boiler & cooling towers, reactor/product 2nd washing and domestic
activity. Total water balance for the project is depicted in Table No. 4.9 & 4.10 respectively.

4.4.2.2 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 COD/ 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 would lead to the contamination of the nearby surface water bodies, soil in
the near vicinity, ultimately resulting in polluting the underground water table reserve through

4.4.2.3 Proposed Mitigation
The effluent loads generated are segregated into two broad streams,
1. High COD/TDS effluent stream will contains aqueous layer from manufacturing process,
1st product wash & scrubber effluent. The HCOD/LCOD effluent would contain around
3.5% salts & 2% COD concentration hence it would be subjected to Pre- primary,
Primary Treatment followed by Stripper MEE with ATFD. The collected condensate
from evaporator will be sent to the aeration tank of conventional ETP for further
treatment.
2. Low COD/TDS stream generated from the reactors washing, 2nd wash of the product,
and blow down from cooling tower & boiler is subjected to the ETP comprises of
primary treatment, aerobic secondary treatment followed by the tertiary treatment. The
condensate from MEE & domestic effluent will be connected to the aeration tank of ETP.
The treated effluent after maximum recycle and reuse in plant will be sent to the Tarapur
CETP (TEPS) for its further treatment and discharge.
3. NGL Fine-Chem Ltd. Have applied for membership of new 50 MLD CETP to be
operated by Tarapur Environment Protection Society and paid membership fees in
installments as the construction is in progress. The details are attached as annexure 4.2
4. In the situation of non-functioning of CETP water will be treated in the ETP and reused
in plant for various uses. If 5% water loss is considered during effluent treatment then
resulting 66 CMD treated effluent will be used for following purpose:
1. pH -- 7 6.5-7.5

4.2.3 Water quality modeling
The project is a green field project; treated effluent from the ETP will be sent to new 50 MLD
capacity TEPS CETP for further disposal. As it is evident that the wastewater generated will not
be discharged into any river/water channel/surface water body, the water quality modeling is not
mandatory for this project as per the Model TOR prescribed by MoEF&CC.
4.3 Noise Environment
4.3.1 Construction Phase
4.3.1.1 Probable Sources
The dominant source of noise from the construction equipments is the engine, usually a diesel,
without sufficient muffling. The activities like pile driving or pavement breaking are other
dominant source of noise generated during construction which is not envisaged for the said
project as there will be no major civil or foundation work. Consideration of probable sources, for
the current scenario can be in two modes, stationary and mobile. Stationary equipment operates
in one location for one or more days at a time with either a fixed power operation (pumps,
generators). Mobile equipment moves around the construction site with power applied in cyclic
fashion such as trucks moving to and fro from the site.
The time varying noise level which are converted into a single number for stationary & mobile
sources are taken from the EPA report which are depicted in the below table.

(Source: U.S Environmental Protection Agency, “Noise from Construction Equipment &Operations, Building Equipment and Home Appliance, “NTID300.1, December 31, 1971)
4.3.1.2 Impact Prediction
Construction activities are characterized by variation in power expended by equipment, with
resulting variation in noise levels with time. Variation in the power is expressed in terms of the
usage factor of the equipment, the percentage of time during the workday that the equipment is
operating at full power. Time varying noise levels are converted to a single number for each
piece of equipment during the operation. Besides having daily variation in activities, major
construction project are accomplished in several different phases. Each phase has a specific
equipment mix depending on the work to be accomplished during that phase.
Each phase has its own noise characteristics some have higher continuous noise level than
others; some have high impact noise levels. The purpose of the assessment is to determine the
combined noise level generated from different equipments & its drop in dB (A) level as it
propagates.
Custic 3.2 developed by Canarina Environment software is used for noise pollution modeling
simulation. The noise dispersion is a complex physical phenomenon that involves turbulences &
non linear dynamics of the irreversible processes which is simplified in a simple equation.

with the natural cycle of animals.
The noise level dissipated as it travels the distance. The drop down in the decibels is calculated
by the modeling software. The Noise level at the plant boundary is found to be 42.2 dB The
drop down level of noise as it travels away from the project site is depicted in the below table,

4.3.1.3 Mitigation
The noise control approaches which can be implemented to curb the noise level in the
construction phase are as follows,
1. Design consideration and project layout: Constructing noise barrier, such as temporary walls
of piles of excavated material, between noisy activities and noise sensitive receivers. Construct
walled enclosure around especially noisy activities or clusters of noisy equipment. Existing green
belt around the plot boundary will act as a noise barrier.
2. Sequence of operations: Combining noisy operations to occur in the same time period. The
total noise level produced will not be significantly greater than the level produced if the
operations were performed separately. Avoid nighttime activities.
Thus, noise from construction would have minor negative impact. However by implementing
appropriate mitigation measures suggested above, these effects are expected to become
insignificant.

Any industrial plant in general consists of various sources of noise in clusters or single. These
clusters/single sources may be housed in buildings of different dimensions made of different
materials or installed in open or under sheds. Generally the plant noise sources include Air
Compressors, Feed Pumps, Condensate Pumps, D.G sets, Recycle Pumps, Boiler ID Fans, air
blowers, cooling towers etc.

4.3.2.2 Impact Prediction
In order to predict noise levels due to the plant operations, which will be contributing to the
ambient noise levels, a sound propagative modeling has been carried out. For predicting the
noise levels at various distances with respect to the plant site, noise levels are predicted using a
user friendly model Custic 3.2 the details of which are elaborated above.
The noise modeling is performed considering the values obtained from the sound level meter
during the monitoring phase of the project. The modeling parameters & procedure is explained in
the above section. Same methodology is adopted for simulating the model considering 4 nos. of
point source.
Effects/Impacts of High Noise Level on Workers during the operational phase
Temporary/Permanent hearing loss

Decreasing in workers performance due to psychiatric disorder
Workers developing Tinnitus due to high level of noise exposure on regular basis.
4.3.2.3 Interpretation
The noise level gets dissipated as it travels the distance. The drop down in the decibels is
calculated by the modeling software. The Noise level at the plant boundary during the
operational phase will be 32 dB (A).

4.4 Details of hazardous and non-hazardous waste generation and their storage, utilizationand management
4.4.1 Construction phase
Construction activities create solid wastes that need to be disposed. Such wastes include sand,
concrete, gravel, stone, bricks, plastic, paper, wood, metal and glass. Technology Information,
Forecasting, and Assessment Council (TIFAC), estimated waste generation during construction
operations is 35 kg/m2. During the construction in a buildup area of 7236 sq.m, 253.26 MT of
waste would be generated for the entire project. The material such as bricks, stone, gravel,
concrete etc. would be utilized in the site for filling of the low lying area as well as for internal

The expected adverse environmental impacts during this phase are the loss of top soil, possible
erosion of soil & other materials towards the surrounding land/water resources and pollution of
soil/water due to spillage of petroleum products used for powering and lubricating vehicles and
construction machinery.
Precautionary/mitigation measures to be adopted
1. Prior to the commencement of any earthwork for construction of the “Formulation andManufacturing Buildings/Sheds” proposed to house the Manufacturing Plants, the perimeter ofthe plot area should be secured with a trench and outer bund, to prevent the erosion of loosenedearth material and other pollutants beyond the plot boundaries.
2. This is particularly important if the earthwork is undertaken during the period of unpredictableweather (e.g. in April/May or September/October) with the possibility of sudden storms withintense rains leading to heavy erosion. It is therefore advisable to commence the earthworkincluding digging for building foundations soon after the termination of monsoon rains(October/November), followed by the construction of Plant structures in the ensuing dry and fairweather period. This will make it possible to dig and shape the moist land with less energyconsumption and also minimize the possibility of soil erosion and pollution of surroundingenvironmental entities.
3. At the start of the earthwork the entire top soil layer (30 cm), which constitutes the most fertilepart of the soil profile, should be removed and stacked separately at a place secured againsterosion. Subsequently, the main earthwork involving digging, leveling and shaping of land forconstruction of buildings and landscaping should be completed. Later, the stacked top soil shallbe uniformly deposited and leveled over the Plot area demarcated for establishing the “GreenBelt”. Any surplus quantity of top soil may be spread over the plot area earmarked as open area.
4. To prevent dust pollution due to construction machinery and vehicles, the operation of thesame shall be strictly regulated and controlled to follow delineated pathways. The vehicularpathways should be periodically sprayed with water tankers, equipped with sprinklers, to prevent“and/or” control the generation of airborne particulate matter.
Moreover, since the project plot allotted is located well within the precincts of the TarapurMIDC, there is no possibility of any adverse impact on the agricultural soils and water resourceslocated beyond the MIDC limits, but within the study area.

Sadekar Enviro Engineers Pvt. Ltd Chapter 4- 35
Probable impacts during operational phase
The possible adverse impacts on soil within and beyond the project plot area during the
operational phase can be as under.
1) Pollution/Contamination of soil if the treated/untreated effluent in any way finds its way to
ground through unforeseen disposal/spillage/leakage, the proposed project will be operating as a
zero liquid discharge unit until the commissioning of new 50 MLD capacity TEPS CETP after
which treated effluent will be sent to CETP for further disposal.
2) Accidental spillage of chemicals (raw material/product) & hazardous waste during storage,
handling, gland leakage of pumps and flange leakage in pipelines within the project plot.
3) Accidental spillage of chemicals (raw materials/products) & hazardous waste during
transportation to & form the project site.
4) Deposition of particulate matter from stack/chimney in the windward direction from the
project site.
Mitigation measures
The possible impacts listed above can be prevented or minimized by adopting certain mitigation
measures as listed below.
1) The conveyance of treated effluent from the project plot to TEPS CETP located at Plot No.
AM-29, Tarapur MIDC will be done by dedicated underground drainage system developed by
MIDC. However since the unforeseen events of spillage/leakage are not predictable which
makes it difficult to install the pre event control measures. However to identify such instances
the project proponent is robustly advised to develop & deploy Standard Operating Procedures
(SOP’s) for regular maintenance checks of the effluent carrying system & communicate the same
to MIDC for appropriate actions.

Chapter 4: Anticipated Environmental Impacts & Mitigation Measures
Sadekar Enviro Engineers Pvt. Ltd Chapter 4- 36
2) All chemicals 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. Also it is robustly advised to develop & deploy
Standard Operating Procedures (SOP’s) to tackle any unforeseen spillage/leakage of chemicals.
3) The transportation of 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 is difficult to install pre event control measures. However for such instances the
project proponent is robustly advised to develop & deploy Offsite Emergency Contingency Plan
& related Standard Operating Procedures to tackle any such unforeseen event.
3) Hazardous waste should be stored in dedicated hazardous waste storage area in 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 should be stored in a dedicated
waste storage area & such waste should be returned to supplier/sold to authorized recycler.
4) To arrest the emission of particulate matter at the source itself, Air Pollution Control Devices
(APCD’s) such as Bag Filter is proposed to be installed and for proper dispersion of pollutants in
atmosphere stack with appropriate height as per CPCB guidelines will be provided.
5) The Standard Operating Procedures which are suggested to be developed to tackle/control any
unforeseen events should be a part of Off Site & On Site Emergency Preparedness Plan.
Overall it can be said that as the project plot is located well within the precincts of the Tarapur
MIDC, there is no possibility of any adverse impact on the agricultural soils beyond the MIDC.

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.
Probable impacts during construction phase
The expected adverse environmental impacts during the construction phase can be
1. Habitat loss due to ground preparation activities
2. Possible erosion of soil & other materials towards the surrounding land/water resources and
pollution of soil/water due to spillage of petroleum products used for powering and lubricating
vehicles and construction machinery.
3. Emissions from construction related works & machineries.
Impact assessment
1. The project activity will involve earthwork related activities in an area of 2256 sq. m. for
construction of manufacturing plants, utility and admin buildings, storage warehouse, security
cabin etc. Now these construction activities will not involve any sort of ground clearing/felling
activities since the areas demarcated for these proposed activities are devoid of any sort of
ground vegetation or trees, hence any sort of habitat loss will not occur.
Precautionary/mitigation measures
1. To avoid possible erosion soil & other materials, the perimeter of the plot area should be
secured with a trench and outer bund.
2. To minimize/arrest dust emissions due to construction related activities within the project plot
regular water sprinkling should be done, also to ensure minimal emissions from the construction
related vehicles and machineries PUC certified vehicles should be used & appropriate
maintenance of construction machineries should be done.

Sadekar Enviro Engineers Pvt. Ltd Chapter 4- 38
4.6.2 Operational phase
Generally the activities which may have adverse impact on the biotic environment during
operational phase may be due to deliberate/unforeseen 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.
1) The treated effluent will be disposed to TEPS CETP located Plot No. AM-29 Tarapur MIDC
& hazardous waste will be sent to Mumbai Waste Management - CHWTSDF at Taloja for
treatment & processing.
The only direct possible impacts due the proposed project may be from the following.
1) Air emissions from burning of fuel for operation of utilities like Boiler, D.G set &
manufacturing process related emissions if at all escape the MIDC industrial estate.
Mitigation measures
1) In order to minimize the air emissions at the source itself, APCD’s such as Bag Filter is
proposed to be installed and for proper dispersion of pollutants in atmosphere stack with
appropriate height as per CPCB guidelines will be provided.
2) 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 standards.
3) In order to arrest the fugitive emissions within the plant premises & to minimize the noise
intensity propagating out of the factory premises, thick green belt comprising of native species as
mentioned in Table No 10.8 of Chapter 10 are suggested for future green belt development.

1) The proposed project does not involves any sort of liquid or solid discharge/disposal on the
ground or in the water bodies within the study area & being located well within the MIDC Estate
which is exclusively meant for industrial developmental activities no adverse impacts are
anticipated on the biotic environment.
4.7 Land environment
Probable impacts during construction & operational phase
The probable impacts on the prevailing land use - land cover aspects in the study area may occurdue to following activities:
1. Generally the developmental activities such as construction & development ofBuilding/Township/Industrial Estate/Special Economic Zones which involve comparativelylarger areas tend to change the prevailing land use & land cover aspects of the larger areadirectly.
2. Also the influx of people associated with such projects during operational & construction
phase 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.
Impact assessment
1. The project in consideration to be executed in a plot area admeasuring 9,174.00 sq. m. at plot
no. S- 18/3, Tarapur MIDC, Boisar, Palghar Dist., Maharashtra, India is a plot specific project
within the precincts of Tarapur MIDC area which is exclusively meant for industrial
developmental activities and already prevails industrial type of land use. However, 2256.00 sq.
m. of the open area in the project plot will be consumed for construction of formulation,
manufacturing and ancillary utilities.
2. Changes in the prevailing land use - land cover aspects of the study area by way of any
ancillary new settlements/setups due to influx of people during construction or operational phase

are not anticipated since the 15-20 no. of workers required during construction phase & 150 no.
of man power required during operational phase will be hired from nearby areas who will daily
travel to & fro from the project site.
4.8 Socio economic environment
It is envisaged that the proposed activity will help to some improvements in the locale specific
socio-economic aspects in the project affected area. 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 proposed activity.
4.9 Odour
4.9.1 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
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.
4.9.2 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, and throat or lung
irritation. Strong odors may cause some people to feel a burning sensation that leads to coughing,

Sadekar Enviro Engineers Pvt. Ltd Chapter 4- 41
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.
4.9.3 Mitigation measures
Mitigation measures that can be implemented for controlling the odour are given below,
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.
Supervision and maintenance: If equipment is supervised and maintained frequently,
leakages in joints, pump gaskets, boilers etc. can be avoided and odour nuisances be
prevented. Ordinary operational practice should include maintenance of equipment to
prevent uncontrolled escape of odour. Odour emissions are often a result of plant
overloading or chemicals spill. It is therefore essential that processes operate correctly
and chemicals are handled carefully. Odour emitted in connection with tank filling
operations can be minimized by means of floating covers or smell charcoal filters at
ventilation outlets.
Good 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

7.4 Aerial Location of Hazardous Atmosphere (ALOHA):
A Quantitative Risk Assessment based on the software ALOHA – Aerial Locations of Hazardous
Atmospheres was carried out. The criteria failure scenarios considered for ALOHA depend on
the type of storage whether above ground tank, drums in storage area or pressurized cylinders as
well as physical state of the chemical stored and chemical properties of the chemical.
ALOHA (Arial Locations of Hazards Atmosphere) is an atmospheric dispersion model
used for evaluating releases of hazardous chemical vapors. ALOHA is a part of software called
CAMEO (Computer Aided Management of Emergency Operation). CAMEO is one of the tools
developed by EPA’s Chemical Emergency Preparedness and Prevention Office (CEPPO) and the
Environmental Impact Assessment Report for proposed manufacturing unit of API & APIIntermediates Chemicals at Tarapur MIDC , Palghar district, Maharashtra.
SEEPL/EIA/F/IND/NGLFCL/002/2016-17/00Chapter 7: Additional Studies
Sadekar Enviro Engineers Pvt. Ltd Chapter 7- 7
National Oceanic and Atmospheric Administration Office of Response and Restoration (NOAA),
to assist front-line chemical emergency planners and responders. For the present calculation
version 5.4.4 is used.
CAMEO suite consists of three parts viz.
1. CAMEO: It is basically a chemical data base provided for calculations.
2. ALOHA: ALOHA allows the user to estimate the downwind dispersion of a chemical cloud
based on the toxicological/physical characteristics of the released chemical, atmospheric
conditions, and specific circumstances of the release.
3. MARPLOT (Mapping Applications for Response, Planning, and Local Operational Tasks):
Graphical outputs include a "cloud footprint" that can be plotted on maps with MARPLOT to
display the location of other facilities storing hazardous materials and vulnerable locations,
such as hospitals and schools. Specific information about these locations can be extracted
from CAMEO information modules to help make decisions about the degree of hazard posed.
Acute Exposure Guideline Levels (AEGL):

THERMAL RADITION EFFECTS:
A Thermal Radiation Level of Concern (LOC) is a threshold level of thermal radiation, usually
the level above which a hazard may exist.
10 kW/(sq m) -- potentially lethal within 60 sec;
5 kW/(sq m) -- second-degree burns within 60 sec; and
2 kW/(sq m) -- pain within 60 sec.
Below are some effects at specific thermal radiation levels for which software was run.
37.5 kw / m2 (100% lethality),
12.5 kw/m2 (1% lethality),
1.6 kw/m2 (no discomfort)
The thermal radiation effects that people experience depend upon the length of time they are
exposed to a specific thermal radiation level. Longer exposure durations, even at a lower
thermal radiation level, can produce serious physiological effects.
OVERPRESSURE EFFECTS:
A major hazard associated with any explosion is overpressure. Overpressure, also called a blast
wave, refers to the sudden onset of a pressure wave after an explosion. This pressure wave is
caused by the energy released in the initial explosion—the bigger the initial explosion, the more
damaging the pressure wave. Blast waves can damage buildings or even knock them flat—often
injuring or killing the people inside them. The sudden change in pressure can also affect
pressure-sensitive organs like the ears and lungs. The damaging effects of the overpressure will
be greatest near the source of the explosion and lessen as you move farther from the source.
An Overpressure Level of Concern (LOC) is a threshold level of pressure from a blast wave,
usually the pressure above which a hazard may exist. In vapour cloud explosion scenario,
ALOHA will suggest three default LOC values. ALOHA uses three threshold values to create
the default threat zones:

• Red: 8.0 psi (destruction of buildings);
• Orange: 3.5 psi (serious injury likely); and
• Yellow: 1.0 psi (shatters glass).
ALOHA software is used to estimate the risk associated with release of pressurized gases. The
summary of ALOHA for different scenarios is attached in Annexure 7.2. ALOHA footprints for
different hazard scenarios are presented in table 7.3.

7.6 Toxicity (Monds) Index
Introduction
The principle and general approach used in the DOW method of hazard evaluation have been
further developed by ICI Mond Division, the revised Mond Fire, Explosive and Toxicity index is
a series of papers by Lewis (1979). The main developments made to the DOW Index in the
Mond Index are:
1. It covers a wider range of process and storage installation
2. It covers the processing of chemicals with explosive properties
3. A calculation procedure is included to allow for the off-setting effects of good design and
control and safety instrumentation
4. The procedure has been extended to cover plant layout
5. Separate indices are calculated to access the hazards of fire, internal explosion and aerial
explosion.
To estimate the Monds Index for raw materials in storage area following,
Chemical storage quantity more than 1.0 metric ton.
Health hazard of raw material is more than 3.
Detailed methodology of Toxicity Index and the toxicity index calculations are given in
Annexure - 7.4. Table 7.6 explains the toxicity index and degree of hazard associated with
respective raw material.

Toxicity (Mond) Index recommendations:
1. Toxic material should be stored in cool place. It should be away from heat and temperature.
2. Toxic material can cause breathing difficulty therefore storage area should be well
ventilated.
3. Dyke or Spill kit should be provided for storage to limit the spill of materials. Suitable
Absorbent like sodium bi carbonate should be used to absorb the spill.
4. The storage area should not be congested and good housekeeping practice should be
implemented.
5. The Toxic materials should be kept with other chemicals according to the compatibility
with each other. E.g. highly flammable chemicals should not be stored near oxidizing agents

The Disaster Management Plan (DMP) is aimed to ensure safety of life, protection of
environment, protection of installation, restoration of production and salvage operations in the
same order of priorities. For effective implementation of the DMP, it should be widely circulated
and personnel training through rehearsals/drills should be organized. Further, the management
should be able to demonstrate that its assessment of the consequences as good supporting
evidence. To tackle the consequences of a major emergency inside the factory or immediate
vicinity of the factory, a DMP has to be formulated and this planned emergency document is
called "Disaster Management Plan". The objective of the Industrial Disaster Management Plan is
to make use of the combined resources of the plant and the outside services to achieve the
following:
Effect the rescue and medical treatment of causalities
Safeguard other people
Minimize damage to property and the environment

Sadekar Enviro Engineers Pvt. Ltd Chapter 7- 40
7.7.11.2 Emergency Shutdown
There are a number of facilities which can be provided to help deal with hazardous conditions,
when a tank is on fire. The suggested arrangements are:
Stop feed
Dilute contents
Remove heat
Deluge with water
Transfer contents. Whether a given method is appropriate depends on the particular case.
Cessation of agitation may be the best action in some instances but not in others.
Stopping of the feed may require the provision of bypass arrangements.
Methods of removing additional heat include removal through the normal cooling arrangements
or use of an emergency cooling system. Cooling facilities, which use vaporizing liquid, may be
particularly effective, since a large increase in vaporization can be obtained by dropping
pressure.
7.7.11.3 Evacuation of Personnel
There could be more number of persons in the storage area and other areas in the vicinity. The
area would have adequate number of exits and staircases. In the event of an emergency,
unconnected personnel have to escape to assembly point. Operators have to take emergency
shutdown procedure and escape. Time Office maintains a copy of deployment of employees in
each shift. If necessary, persons can be evacuated by rescue teams.
7.7.11.4 All Clear Signal
Also, at the end of an emergency, after discussing with Incident Controllers and Emergency Co-
coordinators, the Site Controller orders an all clear signal. When it becomes essential, the Site
Controller communicates to the District Emergency Authority, Police, and Fire Service
personnel regarding help required or development of the situation into an Off-Site Emergency.

7.7.12 General parameters
7.7.12.1Employee Information
During an emergency, employees would be warned by raising siren in specific pattern.
Employees would be given training of escape routes, taking shelter, protecting from toxic effects.
Employees would be provided with information related to fire hazards, antidotes and first aid
measures. Those who would be designated as key personnel and essential employees should be
given training in emergency response.
7.7.12.2 Public Information and Warning
The industrial disaster effects related to this plant may mostly be confined to the plant area. The
detailed risk analysis has indicated that the pool fire effects would not be felt outside. However,
as an abundant precaution, the information related to chemicals in use would be furnished to
District Emergency Authority (normally the Collector) for necessary dissemination to general
public and for any use during an offsite emergency.
7.7.12.3 Co-ordination with Local Authorities
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 and in the
event of an extreme emergency, local authorities’ help should be sought.
In the event of an emergency developing into an offsite emergency, local authority
And District Emergency Authority (normally the Collector) would be apprised and
Under his supervision, the Off Site Disaster Management Plan would be exercised. For this
purpose, 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.

7.8 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.
7.8.1 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 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 within
which the emergency coordinating 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:
Environmental Impact Assessment Report for proposed manufacturing unit of API & APIIntermediates Chemicals at Tarapur MIDC , Palghar district, Maharashtra.
SEEPL/EIA/F/IND/NGLFCL/002/2016-17/00Chapter no - 7: Additional Studies
Sadekar Enviro Engineers Pvt. Ltd Chapter 7- 43
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.
7.8.2 Aspects Proposed to be considered in the Off-Site Emergency Plan
The main aspects, which should be included in the emergency plan, are:
7.8.2.1 Organization
Details of command structure, warning systems, implementation procedures, emergency control
centers. Names and appointments of incident controller, site main controller, their deputies and
other key personnel.
7.8.2.2 Communications
Identification of personnel involved, communication centre, call signs, network, lists of
telephone numbers.
7.8.2.3 Specialized knowledge
Details of specialist bodies, firms and people upon whom it may be necessary to call e.g. those
with specialized chemical knowledge, laboratories.
7.8.2.4 Voluntary organizations
Details of organizers, telephone numbers, resources etc.
7.8.2.5 Chemical information

SEEPL/EIA/F/IND/NGLFCL/002/2016-17/00Chapter no - 7: Additional Studies
Sadekar Enviro Engineers Pvt. Ltd Chapter 7- 44
Details of the hazardous substances stored or processed on each site and a summary of the risk
associated with them.
7.8.2.6 Meteorological information
Arrangements for obtaining details of weather conditions prevailing at the time and weather
forecasts.
7.8.2.7 Humanitarian arrangements
Transport, evacuation centers, emergency feeding treatment of injured, First aid, ambulances,
temporary mortuaries.
7.8.2.8 Public information
Arrangements for: (a) dealing with the media press office; (b) informing relatives, etc.
7.8.2.9 Assessment
Arrangements for: (a) collecting information on the causes of the emergency; (b) reviewing the
efficiency and effectiveness of all aspects of the emergency plan.
7.8.2.10 Role of the Emergency Co-ordinating Officer
The various emergency services should be co-ordinated by an emergency co-ordinating officer
(ECO), who will be designated by the District Collector. The ECO should 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 senior local
authority administrator or even an administrator appointed by the central or state government.
7.8.2.11 Role of the Local Authority
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 works, to obtain the
information to provide the basis for the plan. This liaison should ensure that the plan is
continually kept up to date.
It will be 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
Environmental Impact Assessment Report for proposed manufacturing unit of API & APIIntermediates Chemicals at Tarapur MIDC , Palghar district, Maharashtra.
SEEPL/EIA/F/IND/NGLFCL/002/2016-17/00Chapter no - 7: Additional Studies
Sadekar Enviro Engineers Pvt. Ltd Chapter 7- 45
having for example, sufficient staff and appropriate equipment to cover their particular
responsibilities. Rehearsals for off-site plans should be organized by the EPO.
7.8.2.12 Role of Police
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.
7.8.2.13 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.
7.8.2.14 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 in additional to those available locally, and

SEEPL/EIA/F/IND/NGLFCL/002/2016-17/00Chapter no - 7: Additional Studies
Sadekar Enviro Engineers Pvt. Ltd Chapter 7- 46
a medical "mutual aid" scheme should exist to enable the assistance of neighboring authorities to
be obtained in the event of an emergency.
7.8.2.15 Role of Government Safety Authority
This will be the factory inspectorate available in the region. Inspectors are likely to want to
satisfy themselves that the organization responsible for producing the off-site plan has made
adequate arrangements for handling emergencies of all types including major emergencies. They
may wish to see well documented procedures and evidence of exercise undertaken to test the
plan. In the event of an accident, local arrangements regarding the role of the factory inspector
will apply. These may vary from keeping a watch to a close involvement in advising on
operations. While the industry will activate the DMP and take necessary alleviating measures
and arrange to extend all medical and security support, the factory inspectorate may be the only
external agency with equipment and resources to carry out appropriate tests to assess the impact.

CHAPTER 10: ENVIRONMENTAL MANAGEMENT PLAN
10.1 Introduction
Every industrial development is associated with the positive and negative impacts on environmental
components. Though the 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.

The harvested water will be pumped t one 3, 00,000 L underground tank and used as the intake water for
boiler and for firefighting.
10.9 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 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 will be used to quantify the amount of storm water runoff
per hour in the plant premises.
Rational Method
Q = 10 CiA
Q= Runoff in m3/hr
C = Coefficient of runoff
i = intensity of rainfall in mm/hr
A = Area of drainage in hectares.

Conclusion: The maximum water that can be received on the plant surface during rainfall is not
calculated to be more than 1.45 m3/hr. The dimensions of storm water drainage is given above and the
amount of water flowing through the drain is also calculated which is equal to 217.56 m3. Hence
flooding due to the heavy rainfall in the plant site is not envisaged.
10.10 Solvent Management System
Solvents are one of the costly raw materials which get utilized in API & Chemical Industries; these
solvents are very hazardous in nature, which may cause harm to environmental components. The main
requirement in the industry is minimum inventory maintenance, safe working environment and accurate
dispensing. The solvent dispensing system integrates various operations at solvent yard and production
blocks like unloading, dispensing etc. solvent management start right from solvent unloading, storage,
charging, recovery & reuse of the used solvent.
The solvent utilization, recycling and reuse for proposed project are envisaged as follows:
1) Chemicals will be stored in drums & solvent tank farm yard to avoid handling losses closed feed
system will be provided for filling and unloading of chemicals from the drums.
2) Products will be purified by using various solvents and use solvents will be collected and recycled or
sold to authorized vendors.

Annexure 4.3: Estimation of outlet concentration of fly ash from bag filter.
Ash content of the Indonesian coal is estimated to be 15% w/w.
The coal fired boiler will run for 20 hrs by consuming 5 MT/day coal. Therefore,
Ash quantity of total ash content = 5000/20*0.15
= 37.5 kg/hour of total ash will be generated.
The total ash generated will contain 90% w/w fly ash and 10% w/w bottom ash,
Fly ash quantity of total ash content = 37.5* 90/100
= 33.75 kg/hour of fly ash will be passed through bagfilter.
The fly ash loading to the bag filter will be,
= 33.75 kg/hr* 1/ 6000 m3/hour
= 0.00286 kg/m3
= 5.625 g/m3
Fly ash concentration at the exit of the bag filter with 99.9% removal efficiency will be,
= 5.625 g/m3 * (1- 0.999)
= 0.005625 g/m3
= 0.005625*1000
= 5.625 mg/ m3
6 mg/ m3
The outlet flue gas from bag filter will have fly ash concentration 6 mg/m3 which is wellbelow the national TPM limit equivalent to 100 mg/m3
