1.2. NEED FOR REIA
Every anthropogenic activity has some impact on the environment. More often it is harmful
to the environment than benign. However, mankind as it is developed today cannot live
without taking up these activities for his food, security and other needs. Consequently, there
is a need to harmonize developmental activities with the environmental concerns.
Environmental impact assessment (REIA) is one of the tools available with the planners to
achieve the above-mentioned goal.
It is desirable to ensure that the development options under consideration are sustainable. In
doing so, environmental consequences must be characterized early in the project cycle and
accounted for in the project design.
The objective of REIA is to foresee the potential environmental problems that would arise out
of a proposed development and address them in the project's planning and design stage. The
REIA process should then allow for the communication of this information to:
o The project proponent;
o The regulatory agencies; and,
o All stakeholders and interested groups.
REIA integrates the environmental concerns in the developmental activities right at the time
of initiating for preparing the feasibility report. In doing so it can facilitate the integration of
environmental concerns and mitigation measures in project development. REIA can often
prevent future liabilities or expensive alterations in project design.
1.3 INDIAN POLICIES REQUIRING REIA
Environmental Impact Assessment Report has been prepared for obtaining Environmental
Clearance for KCIL’s proposed expansion of organic chemical and addition of new organic
as well as inorganic chemical manufacturing activities at Padana. The manufacturing of
organic chemical falls under EIA Notification issued in September – 2006.
REIA of Kutch Chemical Industries Limited Chapter 1 Introduction

o Screening
o Scoping and consideration of alternatives (ToR)
o Baseline data collection
o Impact prediction
o Assessment of alternatives, delineation of mitigation measures and environmental
impact statement
o Environment Management Plan
o Decision making
o Monitoring the clearance conditions
1.5 METHODOLOGY & SCOPE OF REIA
The methodology of EIA adopted for KCIL is based on the guidelines of MoEF. Actions
carried out were as follows:
o The MoER has approved ToR vide EIA-10-2008-330-E
Dated :12.02..2010. Baseline information with respect to air, water, noise, and land

2.4.2 PROCESS DESCRIPTION
2.4.2.1 Vinyl Sulphone & Vinyl Sulphone Condense:
Process Description:
Chloro Sulphonation:
Chloro Sulphonic Acid is charged into the sulphonation reactor. Acetanilide is then
slowly added to maintain the temperature below 80° C. The temperature is then
maintained between 50-60 °C. The batch thus prepared is transferred to the storage
tank.
Dumping:
Sulphonated mass is charged into the Reactor cooled with brine. Ice water is then
added slowly to remove all the HCl formed due to decomposition of excess Chloro
Sulphonic Acid. The HCl is scrubbed and absorbed in water to make HCl. Further Ice
water is added to dilute the concentrated Sulfuric Acid formed due to the
decomposition of Chloro Sulphonic Acid. Here we get of Sulfuric Acid of strength
30-40%.
The mass is then filtered out (ASC Cake).
Reduction:
Sodium Bi Sulphite slurry is added to the reactor. The pH is maintained neutral by
adding Caustic Lye. The ASC wet cake is then charged under controlled temperature
and pH. After addition is over the temperature is raised up to 50 °C. The mass is then
filtered and transferred to condensation vessel.
Condensation:
The reduction mass in condensation vessel is maintained at 50°C. Ethylene Oxide is
slowly added. The pH is maintained to 5-7 by adding dilute sulphuric acid. The
material after condensation is transferred to the Nutsch Filter. The Mother liquor is
stored in storage tank. The condensed product is then washed and dried.

2.4.2.10 Sulphuric Acid As
Sulphuric Acid (98%)
Oleum (23 % & 65%)
Liquid SO3
Process Description:
The process for the manufacture of sulphuric acid comprise the following steps:
1. Solid Sulphur after weighment is fed to sulphur melter which is provided with
steam coils. The ash content of the molten sulphur settles in the melter cum settler
and molten sulphur free of impurities is pumped to the sulphur burner where it is
burnt with air. Sulphur is converted in to SO2 in the sulphur burner as per the
following reaction
S + O2 SO2
2. SO2 is further converted to SO3 in presence of Vanadium Pentoxide catalyst in
the converter as per the following reaction:
SO2 + ½ O2 SO3
The conversion of SO2 to SO3 is carried out in stages in all the five pass of the
convertor. The conversion is optimized by intermediate cooling of gases between
the different stages and also by interpass absorption of SO3 after 3rd pass of the
convertor.
3. The gas from the 3rd & 5th pass of the convertor containing SO3 is cooled & then
fed to the interpass & final absorption tower where SO3 is removed by circulating
Sulphuric Acid in the absorption towers. The concentration of sulphuric acid is
controlled by addition of water in the pump tank.
Air for sulphur burner is routed through Air Filter to drying tower and further to
suction side of Centrifugal Air Blower. 98.5% acid is circulated through drying
REIA of Kutch Chemical Industries Limited Chapter 2 Project Description
April - 2010 60
tower at 70°C, thus heating to 125°C before entering sulfur burner. This system
helps to increase generation of steam and hence power generation.
4. SO2 emission during start up of the plant is controlled by a Venturi Scrubber
using alkali as scrubbing medium. The plant therefore does not cause any
pollution either during start up or during normal operation.
The process as described above has been divided into five main sections described as
follows:
1. Sulphur Circuit
The weighed quantity of sulphur of about 99.5% purity is fed to the first
compartment of sulphur melter. The heat for melting sulphur is provided
through steam coils. The optimum pressure to be maintained for melting
sulphur in the first compartment is upto 7 kg/cm2 G.
The molten sulphur flows from compartment no. 1 to pumping compartment
through underflows/overflows. The sulphur pumps for feeding sulphur are
fitted in pumping compartment. The total time of retention in the
compartments corresponds to more than 72 hrs at normal rated production
capacity of the plant. In order to achieve optimum results, it is necessary that
the feeding of sulphur to the melter should be maintained at specified
temperature of 135 °C. All compartments are fitted with steam coil to provide
the necessary heat for maintaining the temperature of molten sulphur at the
desired level. Molten sulphur from the pumping compartment is pumped to
the sulphur burner through one of the submersible type sulphur pumps
through specially designed sulphur feeding gun. The rate of feed of sulphur to
the sulphur burner is controlled by operation of sulphur feed control valve.
REIA of Kutch Chemical Industries Limited Chapter 2 Project Description
April - 2010 61
Drain lines have been provided in the molten sulphur discharge line at two
different points.
The optimum steam pressure for coils located in 2nd, 3rd , 4th through pumping
compartments of the sulphur melter is around 4 kg/cm2 G. This regulated
steam pressure is achieved through pressure reducing valve. Molten sulphur
line starting from the discharge flange of the sulphur pump to the inlet of the
sulphur burner is suitably steam jacketed to maintain correct temperature of
molten sulphur fed to the sulphur burner.
2. SO2 Scrubber
It is very important that SO2 emission during plant startup is controlled within
persmissible limits. This is achieved by use of a alkali scrubber located after
the final absorption tower where gas is scrubbed with circulating alkali
solution.
3. DM and Water Softening Plants
For generation of steam of high quality DM water is required for this purpose
RO plant and DM plant will be installed.
4. The plant is provided with data logging system through DCS control circuits for
control of parameters like Acid concentration control, pump tank level control, Boiler
feed water level control, boiler feed water from deaerator temperature control. All
the output signals are fed to a computer and output data is collected based on reports
to be prepared including log sheets.

Processs Description
Oleum & Liquid SO3
Oleum (23%)
Oleum 23% is manufactured by absorbing SO3 gas with Sulphuric Acid.
H2SO4 + SO3 H2S2O7
Oleum 23% means free SO3 in the product is 23%, which is equivivalent to 105.17%
Sulphuric Acid. This way 23% Oleum is equivalent to 1.07 of 98% Sulphuric Acid.
The sulphur required for 1 ton of 23% oleum is 0.326 x 1.07 = 0.349 ton.
Oleum (65%)
Oleum 65% means, the free SO3 in this product is 65% which is equivivalent to
114.626% sulphuric acid. This way the oleum 65% is equivalent to 1.17 times of 98%
sulphuric acid.
The sulphur required for 1 ton of 65% Oleum 0.326 x 1.17 = 0.381 ton
Liquid SO3
Liquid SO3 is = 1.25 times of 98% Sulphuric Acid. The Sulfur required for 1 ton of
liquid SO3 = 0.326 x 1.25 = 0.41 ton.

2.7 WASTEWATER MANAGEMENT
The wastewater generated will be segregated and treated separately. After proposed
expansion a total of 486 KLD of Industrial & 24 KLD of domestic wastewater will be
generated. The industrial wastewater will be further segregated considering its pollution load
and finally be treated within premise.
SEGREGRATION OF THE WASTE STREAMS:
The Various Streams generated from the industrial activity will be as follows:
Stream A: Process wastewater from Vinyl Sulphone, which will have high concentration of
COD & BOD.
Stream B: Process wastewater from Sulphuric Acid Plant, TC Plant, Chloro Sulphonic Acid
Plant, DASDA Plant, DMS Plant, DMA Plant.
Stream C: Utility wastewater (viz Boiler blow down, Cooling water blow down,
Regeneration & Washing
Stream D: Domestic wastewater.
The streams from the process will be conveyed to the equalization/ collection tank and is
given a primary treatment. The utility wastewater will be directly taken into the final
collection tank after the physical screening of the wastewater. The domestic wastewater will
be directly fed in to the aeration tank of the Effluent Treatment Plant. Hence only wastewater
which required the full treatment is process water i.e 64 KLD.

3.2.1 TOPOGRAPHY
The elevation of the region varies between 13 meter and 284 meters above M.S.L. The slope gradient
towards south.
3.2.2 HYDROLOGY
Hydrology is the science that deals with the depletion and replenishment of water resources. It deals
with surface as well as ground water. The water below the water table is known as ground water and
water above the water table is known as soil moisture. The region above water table is divided in to
three zones, capillary zone, intermediate zone & soil zone. The distance about 0.3 to 3m depending
upon the texture of a zone is called a capillary zone. Extending down from the ground surface is the
soil zone, which is defined as being the depth of overburden that is penetrated by the roots of
vegetation through out this zone; the moisture content varies tremendously , ranging from a partly
saturated state during and immediately periods of heavy rains to a minimum content after a long
continued drought.
The region between the capillary zone and the soil zone is called the intermediate zone. Ground water
is located beneath the ground surface in soil pore spaced and in the geological formation. A formation
of rock/soil is called an aquifer, where it can yield a usable quantum of water. The depth at which soil
pore spaced becomes saturated with water is called the water table. Ground recharged from and
eventually flows to the strata naturally. Ground water is also often with drawn for agricultural and
industrial use by construction and operation extraction wells, results depletion of water table. Surface
precipitation, streams and river naturally replenish ground water, when this recharge reached the
water table. Ground water is a highly useful and abundant resources, but in arid or semi arid region
like Kutch region, the most evident problem that may result from this is a lowering of the water table
beyond the reach of existing wells.
Infiltration: Infiltration is the process by which water on the ground surface enters the soil. Infiltration
rate in soil science is a measure of the rate at which soil is able to absorb the rainfall or irrigation. It is
measured in mm/hr. the rate decreases as the soil becomes saturated. If the precipitation rate exceeds
the infiltration rate, runoff will usually unless there is some physical barrier.
The rate of infiltration is affected by soil characteristics including ease of entry, storage capacity and
transmission rate through the soil. The soil texture and structure, vegetation type and cover, water
content of the soil, soil temperature and rainfall intensity all play role in controlling infiltration rate
and capacity. For example coarse grained sandy soil have larger spaces between each grain and allow
water to infiltrate quickly, while in sandy clay soils like in Padana pore spaces are relatively smaller
than sandy soils but retention of water will be little more than sandy soils. Vegetation creates more
porous soils by protection the soil from pounding rainfall, which can close natural gaps between soil
REIA of Kutch Chemical Industries Ltd. Chapter 3 Baseline Environmental Status
April - 2010 119
particles and loosening soil through root action. This is why forested areas have the highest
infiltrations rate of any vegetative types.
The process of infiltration can continue only if there is room available for additional water at the soil
surface. The available volume for additional water in the soil depends on the porosity of the soil and
the rate at which previously infiltrated water can move away from the surface through the soil. The
maximum the rate at water can enter a soil in a given condition is the infiltration capacity. If the
arrival of the water at the soil surface is less than the infiltration capacity , all of the water will
infiltrate. If rainfall intensity at the soil surface occurs at a rate exceeds the infiltration capacity,
pounding begins and is followed by runoff over the ground surface.
It was found out that infiltration capacity rapidly declines the early part of a storm and then tends
towards an approximately constant value after a couple of hours for the remainder of the event.
Previously infiltrated water fill the available storage spaces and reduced the capillary forces drawing
water in to the pores. Clay particles in the soil may swell as they become wet and thereby reduced the
size of the pores. The hydrology details of the area have been mentioned below:

* Due to the variable rainfall, there is often not enough water for release in the canal networks and
therefore the irrigation scheme of Kutch utilize only 28% of their potential.

3.3 WATER QUALITY
Water is a vital essential commodity necessary for the survival of vegetation, animals, humans, and
for the proper balance of eco system itself. Hence it is necessary to study the quality of water in the
study area to find out if industrial activities in and around the area have caused any deterioration in
the environmental quality with respect to surface and ground water sources, so that the health and
growth of humans, flora, fauna and soil conditions are not affected adversely. This assessment may
also serve as a baseline to compare with the post establishment data for taking necessary corrective
measures if any of the parameter tends to exceed the prescribed limit.
Details of the water-sampling locations & their characteristics bas been represented below in Table
3.13 and Table 3.14 respectively.

The purpose of this study was to:
o Assess the water quality characteristics for critical parameters.
o Evaluate the impacts on agricultural productivity with respect to water quality, habitat conditions, recreational resources and aesthetics in the vicinity.
o Predict impact on water quality due to this project and its related activities.
Reconnaissance survey was undertaken and the monitoring locations were finalized based on
o Location of watercourses.
o Location of residential areas / likely impact areas.
o Areas likely to represent baseline conditions.
The samples were collected and analyzed as per the procedures specified in ‘Standard Methods for the
Examination of Water and Wastewater’ published by American Public Health Association (APHA).
Samples for chemical analysis were collected in polyethylene carboys. Samples collected for metal
content were acidified with 1 ml HNO3. Samples for bacteriological analysis were collected in
sterilized glass bottles. Selected physio-chemical and bacteriological parameters have been analyzed
for projecting the existing water quality status in the study area. Parameters like and pH, Color, Odour
& Taste were analyzed at the time of sample collection. The results obtained are shown in Table 3.4
below.
Most of the rivers in the kutch district non-perennial; water is available in monsoon season only.
Hence the water sample collected are of ground water only.

mg/lit, which is acceptable for non drinking purpose. The hardness of water samples of the project
site (i.e. 350mg/lit) is within the limit specified for drinking water standards.
3.4 AIR MONITORING
This section describes the selection of sampling locations, methodology adopted for sampling,
analytical techniques and frequency of sampling.
3.4.1 SELECTION OF SAMPLING LOCATIONS
The baseline status of the ambient air quality has been assessed through a scientifically designed
ambient air quality-monitoring network. The design of monitoring network in the air quality
surveillance program has been based on the following considerations:
o Meteorological conditions.
o Topography of the study area.
o Representative air quality for obtaining baseline status.
o Representative of likely impact areas.
In order to establish the baseline air quality status in a study area, 8 ambient monitoring stations were
selected within the 10.0 Km Radius of the project site. These locations were selected on the basis of
even distribution over the study area taking in to consideration various factors like topography of the
region, proximity of sensitive establishment and human settlements, industrial activities in the area, its
proximity, down wind direction etc. The details of the ambient Air quality-sampling locations &
National Ambient Air Quality Standards are given in Table 3.15 & Table 3.16 and their locations are
indicated in MAP 3.3.

3.4.3 METHODOLOGY ADOPTED FOR AIR QUALITY SURVEY
3.4.3.1 FREQUENCY AND PARAMETERS FOR SAMPLING
The frequency adopted for sampling was two days per week at eight locations for four weeks. The
baseline data of air environment was generated for the parameters mentioned as under:
o Sulphur dioxide (SO2).
o Oxides of Nitrogen (NOx).
o Chlorine (Cl2)
o Hydrochlorinc Acid (HCl)
o Respirable Suspended Particulate Matter (PM10)
3.4.3.2 DURATION OF SAMPLING:
The duration of sampling of SPM, RSPM, SO2, and NOx was 24 hours. This was done to compare
with the present revised standards mentioned in the latest Gazette notification of the Central Pollution
Control Board (CPCB) (JULY 20, 2002).
3.4.3.3 METHOD OF ANALYSIS:
The air samples were analyzed as per standard methods specified by Central Pollution Control Board
(CPCB), Indian Standards: 5184.
3.4.3.4 SAMPLING AND ANALYTICAL TECHNIQUES
Ambient Air laden with Suspended Particulate Matter enters the system through an inlet in the
sampler. As the air passes through the cyclone, coarse, non-respirable dust is separated from the air
stream by centrifugal forces. These separated particles get collected in a cup attached to the hopper
bottom of the cyclone. The remaining particles, which constitutes respirable fraction, is collected on
the filter paper; mounted on the HVS machine. A tapping is provided on the suction side of the blower
to provide suction for gas sampling through a set of impingers. Samples of gases were drawn at a flow
rate of 1.5 lt. per minute (LPM) for NOx & SO2
3.4.3.5 SELECTION OF INSTRUMENTS FOR AIR QUALITY SAMPLING 8. &
CALIBRATION
Calibration charts have been prepared for all gaseous pollutants. The calibration is carried out when
ever new absorbing solutions are prepared. The instruments used for air sampling were pre-calibrated.

3.5 SOIL QUALITY
From the Environmental point of view, soil can be considered as an important component of the
ecosystem as urbanization, Industrialization etc., have a direct bearing on the land surface, which in
turn is intimately linked to the soil of the region concerned.
Hence knowledge of soil characteristics, erosion aspects, soil fertility etc., is vital for planning and
implementation of afforestation / green belt development measures as a part of maintaining ecological
balance of the region. Location and operation of industries, generation and dumping of wastes
materials / solid wastes etc. could directly or indirectly affect the soil quality of the surrounding area.
Hence the study of soil characteristics in and around the proposed planned site becomes a necessary
part of environmental impact assessment study. Soil Sampling locations & their characteristics are
shown in Table 3.20, 3.21 & Map 3.1.

3.5.1 GENERAL OBSERVATIONS
Soil Electrical Conductivity (EC) assessment measures the soluble salts in the soil. EC of soil depends
on the porosity, water content, salinity level, cation exchange rate and temperature. The EC of the soil
was found 0.12 – 0.15 m.mhos/cm. This can be classified as neutral.
The cation exchange capacity of a soil refers to the amount of positively charged ions a soil can hold.
When dissolved in water, the nutrients are either positively charged or negatively charged. (e.g.
Calcium (Ca++), magnesium(Mg++), Potassium(K+), Sodium(Na+), Hydrogen(H+) and
ammonium(NH4+). Soils have a slight excess of negative charge sites due to the presence of organic
matter. Thus higher the organic matter content, higher is the CEC of the soil. The soil with high cation
exchange capacity will tend to hold onto the positively charged nutrients better than soil with a low
Cation exchange capacity. The low level of CEC value shows that the soil is devoid of organic matter.
Specific gravity of the soil comes to 1.98-2.512 with field moisture content is 10.61-13.21%.
Porosity refers to the propensity of a material to allow fluid to move through its pores or interstices.
Porosity is an important soil parameter for any project where flow of water through soil or rock is a
matter of concern. The porosity was found 35.62-46.81%.
3.6 NOISE MONITORING
Industrialization, urbanization, construction activities etc., have a direct bearing on the noise level of
the surrounding environment pertaining to such activities. Noise intensity beyond certain tolerable
limits may interfere with communication in work, apart from causing annoyance and health hazards.
Impact of noise on environment depends on various factors such as intensity distance from source,
time of exposure and nature of activities, machineries, traffic etc. Hence, it is necessary to measure the
ambient noise levels in order to determine the environmental impact so that appropriate measures
could be adopted if needed to abate noise pollution.
The main objective of noise monitoring in the study area is to establish the baseline noise levels, and
assess the impact of the total noise that is expected to be generated during the construction, and
operation of the proposed project activities. Noise monitoring has been undertaken for 24 hr at each
location.
Noise monitoring was carried out to establish ambient noise levels in the study area. The details of the
sampling stations are given below in the Table 3.22 and their locations area is shown in Map 3.1.

3.7 METEOROLOGY
For the interpretation of baseline conditions and also for predicting the incremental levels of air
pollutants the micro-meteorological data forms an indispensable part. The meteorological data
recorded during the monitoring period is a useful tool for the interpretation of the baseline condition
as well as for the input, to predictive models for air quality dispersion. Historical data on
meteorological parameters also plays an important role in identifying the general meteorological
status of the region. Site-specific data can be compared with the historical data in order to identify
changes, which may have taken place due to the various developments in the area. The data of
summer season has been collected and presented in the form of Windrose.

4.0 ENVIRONMENTAL IMPACT ASSESSMENT
4.1 INTRODUCTION
Impact assessment describes identification and appraisal of various impacts due to the
proposed project.
"Environmental Impact" can be defined as any alteration of environmental conditions or
creation of a new set of environmental conditions, adverse or beneficial, caused or induced by
the action or set of actions under consideration.
Generally, the environmental impacts can be categorized as either primary or secondary.
Primary impacts are those, which are attributed directly by the project, secondary impacts are
those, which are indirectly induced and typically include the associated investment and
changed patterns of social and economic activities by the proposed action.
The impacts have been predicted for the proposed construction project assuming that the
pollution due to the existing activities has already been covered under baseline environmental
monitoring.
4.2 IMPACT ASSESSMETN MATRIX

4.3 OVERALL IMPACTS
The impacts arising out of the said projects have been listed and studied in depth.
4.3.1 IMPACT ON LAND/SOIL
The sewage generated will be treated in the septic tank & soak pit. KCIL will take all
reasonable precautions for wastewater seepage. This will prevent soil contamination.
The proposed land is having fairly flat terrain. The construction activities may result in loss
of topsoil to some extent in plot area where the development has to be made. The topsoil will
be conserved and will be reutilized for gardening/landscaping. Hence, soil quality will not be
adversely impacted by KCIL plant operations.
Further, it is emphasized that all precautionary measures have to be strictly followed as
mentioned in the in the Environmental Management Plan given to prevent soil contamination
in the future.
The existing unit having industrial use only. Hence the land, which is meant for Industrial
purpose, will be utilized for Industrial Purpose only. Hence this is going to cause no impact
on landuse.
4.3.2 IMPACT ON AIR QUALITY.
The baseline status of the Ambient Air Quality shows that PM is well within the prescribed
limits of the GPCB. There would be marginal increase in the suspended particulate matter,
SOx and NOx levels due to the vehicular movement inside the premises.
Location and distance of ambient air monitoring stations were selected as already mentioned
in Chapter-3. Ambient air monitoring carried out in summer season shows that the ambient
air quality for RSPM, SPM, SO2, NOx, HCl, & Cl2 are within the limits specified by CPCB.
Impact on ambient air due to KCIL plant operations will be due operation of Industrial
Boiler, Incinerator and process emission from the DASDA plant & CaCl2 plant. The likely
emission rate from the flue gas has been given in the following table. The ground level
concentration have been identified using Industrial Source Complex ISCST3 model, which
approved by USEPA and CPCB-New Delhi.
The Dispersion modelling assumptions are considered as follows:
REIA of Kutch Chemical Industries Ltd. Chapter 4 Environmental Impact Assessment

i. The receptor locations for 36 wind directions starting with 10 degrees and incrementing
with 10 degrees for radial distances viz. 50m, 100m, 200m, 300m, 500m, 1000m,
2000m, 3000m and 5000m has been taken for the Air Quality Modelling.
ii. The impacts of the pollutants were identified up to 10000 meters.
iii. The terrain of the study area was considered as FLAT.
iv. Stability Class was evaluated based on Temperature Profile and Cloud Cover.
v. The mathematical equations used for the dispersion modelling assumes that the
earth surface acts as a perfect reflector of plume and physic-chemical process,
such as dry and wet deposition, and chemical transformation of pollutants are
negligible.
vi. The micro-meteorological data viz. Temperature, Wind Speed, Wind Direction
and Cloud Cover has been given by the client for the year 2009.

For flue gas emission PM & SO2 emission rate has been calculated based on ash & sulphur
content of the fuel and for NOx emission factor has been considered (using FIRE Software).
For process emission permissible limits has been considered for calculating emission rate.
The Air Dispersion Modelling results have been discussed below:
It is observed that due to operation of the proposed activity additional GLC of various

Hence, it can be observed from the above predictions that GLC will always remain within
limits and project activities will not have any adverse impacts on the environment.
Further, it is emphasized that all the emissions have to be strictly controlled as mentioned in
the mitigation measures in the Environmental Management Plan given in Chapter 5, to
maintain ambient air quality within norms in the future.
REIA of Kutch Chemical Industries Ltd. Chapter 4 Environmental Impact Assessment

4.3.3 IMPACT ON GROUNDWATER
Water requirement for project will be met through the Gujarat Water Infrastructure Limited
(Namrada Water Pipeline). The water required will be 1516.5 KLD. The wastewater
generated will be treated within the premises and finally utilized for gardening & firefighting
requirement.
a. Impact on receiving surface water body:
No adverse impact is envisaged on the ground water
b. Impact on ground water quality:
No ground water will be utilized for the project. Ground water was tested at three
different locations in the study area. The ground water norms were compared to
IS:10500 (1991) for evaluation. The TDS is in the range of 2500-3500 mg/lit and is
not fit for drinking.
KCIL will take all necessary precautions to make its solid waste and raw material
storage / treatment areas impervious to water and leachate migration.
It follows from the above that ground water quality will not adversely impact by KCIL
activities.
Further, it is emphasized that all precautionary measures have to be strictly controlled as
mentioned in the mitigation measures discussed in Environmental Management Plan given in
Chapter 5, to maintain ground water quality within norms in the future.
4.3.4 IMPACT ON NOISE LEVELS
The noise level within the plant premises has been tabulated in Table 3.20.
As per observations, the Ambient Noise Level is within norms of Industrial Area. With the
implementation of the mitigation measures proposed, the noise levels at plant boundaries will
be well below the limits specified for industrial areas.
The major sources contributing to Noise pollution during the plant operation will be
Compressor, Boiler, Pumps, and Turbine etc. The operation of the equipment will generate
noise ranging between 70-80 dB (A). It follows that noise levels are not adversely impacted
by KCIL plant operations.

industry, Government, Regulating agencies like Pollution Control Board working in the
region and more importantly the population of the area need to extend their co-operation and
contribution.
It has been evaluated that the project area will not be affected significantly with proposed
project. Mitigation measures at the source level and an overall Management Plan at the site
level are elicited so as to improve the surrounding environment.
The following mitigation measures are recommended in order to synchronize the economic
development of the project area with the environmental protection of the region. The
construction phase impacts are mostly short term, restricted to the plot area and not envisaged
on the larger scale. In the operational phase the environmental impacts are due to continuous
operation of the project, hence, the emphasis in the Environment Management Plan (EMP) is
to minimize such impacts. The emphasis on the EMP development is on the following:
o Mitigation measures for each of the activities causing the environmental impact
o Monitoring plans for checking activities and environmental parameters and monitoring responsibilities
o Role responsibilities and resource allocation for monitoring
Following sections describes the environment management plan proposed for construction
and operation phases.
5.2. MITIGATION MEASURES
Each of the activities during production phase is critically reviewed for suggestion of
mitigation measures. Based on this the Table 5.1 to 5.4 gives the mitigation measures for the
activities considered to be causing significant environmental impacts during production
phase.
In general the best housekeeping practices are incorporated in the design as well as in
production phase to reduce the short terms impacts due to the proposed activities.

7.0 CONCLUSION
7.1 SUMMARY OF ENVIRONMENTAL IMPACTS
1. Ambient air
From ambient air quality survey and quantified air emission it can be concluded that KCIL
activities will not have adverse impact the ambient air quality.
2. Water resources
Water will be supplied by the Gujarat Water Infrastructure Limited (Narmada Pipeline
Project). No ground water will be utilized for the project activities. Hence no impact on the
ground water resources..
3. Ground water quality
Ground water was tested at three different locations in the study area as described. The
ground water norms were compared to IS:10500 (1991) for evaluation. No ground water will
be used for the project activities. KCIL will take all reasonable precautions to make its solid
waste storage areas impervious to water and leachate migration.
It follows that ground water quality is not adversely impacted by KCIL activities.
4. Noise levels
Noise levels shall be within limits specified by GPCB at plant boundary, after
implementation of the mitigation measures. Hence there is no adverse impact on noise levels
by KCIL operations.
5. Soil quality
KCIL will take all precautions to make its solid waste storage / treatment areas
impervious to water and leachate migration. This will prevent soil contamination.
It follows that soil quality is not adversely impacted by proposed plant operations.
REIA of Kutch Chemical Industries Ltd. Chapter 7 Conclusion
April - 2010 171
7.2 CONCLUSION
The study brings out the following points:
1. The flue gas emission from Industrial Boiler, Incinerator and Power Plant will be released
through well designed stack with adequate height with proper air pollution control
equipment. The Ambient Air Quality Modelling study indicates that predicted ground
level concentration will be remain within National Ambient Air Quality Standards.
2. The wastewater generated is being treated in well designed Effluent Treatment Plant. The
treated wastewater will be finally used for gardening & firefighting requirement.
3. The noise generation will be reduced as per the measure provided in Environmental
Management Plan.
4. The Risk associated have been identified by conducting Risk Assessment, HAZOP and
recommendation of the same will be implemented. Moreover On Site Emergency Plan
has also been prepared to tackle the emergency if arises.
5. Socio-economic benefits due to creation of direct / indirect employment. An additional
100 nos. of person is likely to get employment due to the project. Moreover due to the
project other direct and indirect business will get benefited.
