1.0 INTRODUCTION
1.1 Background
M/s. Tagros Chemicals India Limited (TCIL), located at the
SIPCOT Industrial estate,Pachayankuppam village, Cuddalore district
in the TamilNadu State is a leading manufacturer of technical grade
pesticides and intermediates. TCIL is having the consent of the
TamilNadu Pollution Control Board (TNPCB) for the production of D.V.
Acid Chloride, Quinopyramine Sulphate, Cypermethrine / Permethrin /
Alphacypermethrin / Deltamethrin, Oxyclozanide, Hexaconazole /
Propiconazole / Dicamba / Tricyclazole and Metaphenoxy benzyl
alcohol at the rate of 145.75 T/Month. They also have the consent to
produce 2545 T/Month of by products such as hydrochloric acid, spent
sulphuric acid, sodium sulphite solution, sodium sulphite powder,
hydrogen bromide solution and aluminium chloride solution.
The gross assets value of the project cost is 20 crores.
1.2 Need of EIA
Rapid urbanization and industrialization particularly in developing
countries have resulted in a considerable impact on the environment.
During the last few decades there has been a growing realization that
development cannot be sustained unless the environment is
preserved. Hence, Government is making it mandatory that industrial
and other development projects be taken up only after conducting
Environmental Impact Assessment Study of the same. So that, the
quality of the environment is not only preserved but could also be
enhanced. According to the procedures laid down, Tamil Nadu Pollution
Control Board (TNPCB) and Ministry of Environment and Forests
(MoEF), New Delhi is empowered to scrutinize proposals for industrial
projects only if they are accompanied by EIA report. Unless the report
on a proposed project is cleared, the project cannot be implemented.
Tagros Chemicals India Limited
Chapter I 2
1.3 Objectives of EIA-EMP
The basic objective of EIA-EMP exercise is to minimize adverse impacts
of any development on the environment. Besides fulfilling the legal
requirement for getting environmental clearance from concerned
authorities, the specific objectives of the EIA-EMP are as follows.
To review the current environmental status of the plant site and its
surrounding area and to estimate the pollution that would occur
after the expansion of the plant and its impact on the surrounding
environment.
To suggest EMP including pollution control methods to ensure that
the pollution will be well within the limits prescribed by the CPCB
and TNPCB, and to minimize the adverse environmental impacts of
the plant, so that the quality of environment is not only preserved
but also be enhanced.
To propose a post-project environment-monitoring plan to ensure
that the EMP achieves it�s desired objectives.
1.4 Methodology for EIA-EMP
The methodology is based on existing guidelines and has the following
distinct features.
The existing environmental quality in the project area has to be
assessed.
Potential sources of pollution have to be identified.
Potential environmental impacts have to be identified and assessed
qualitatively. The changes in the quality of environment have to be
identified.
An EMP has to be drawn up to maintain and enhance the
environmental quality around the proposed project area.
Tagros Chemicals India Limited
Chapter I 3
A post-project environment-monitoring plan has to be suggested to
monitor the changes in environmental quality after the
implementation of the project.
Potential benefits of EIA-EMP have to be discussed.
1.4.1 Assessment of Existing Environmental Quality
In the case of an industrial project almost all components such as air,
water, land, soil, noise, etc., get equally affected. Hence, the existing
quality of environment viz. air, water, land, soil and socio-economics
of the people in the area have been assessed.

2.5 Manufacturing Process
Common Production Steps
Alphamethrin / Cypermethrin / Permethrin and Deltamethrin are
manufactured starting from acrylonitrile and carbon tetrachloride. The
Manufacturing process is described in the following parts.
First acrylonitrile is condensed with carbon tetrachloride in the
presence of cupric chloride as catalyst and acetonitrile solvent. The
reaction product is distilled to get pure tetrachloro butyronitrile (CBN).
CBN is then hydrolysed by dilute sulphuric acid to get
tetrachlorobutyric acid (CBA). The spent acid produced in this process
is separated and sent to storage tank for sale to authorized dealers.
Tetrachloro butyric acid thus obtained in the third stage is reacted with
thionyl chloride to produce tetrachloro butyric acid chloride (CBC). The
off gas is scrubbed in water and then with caustic lye. The resulting
hydrochloric acid and sodium sulphite solution are stored in 30 KL
Storage tank and 45 KL Storage tank Respectively and are sold to
authorized dealers.
Tetrachloro butyric acid chloride (CBC) is condensed with isobutylene
to get a cyclic compound 2-chlorocyclobutanone (2-CB). This product
is separated and is crystallized.2-CB is isomerised to 4-
chlorocyclobutanone 4-CB) and is reacted with caustic solution and
finally neutralized to get cypermethric acid (CMA) in hexane. Cis-CMA
is isolated from CMA solution by selective crystallization. The aqueous
is separated and is sent for cypermethrin production. The process floe
diagram is shown in fig 1.The chemical reaction diagram is shown in
fig 2.The flow of the master plan in all the reactors is shown in fig 3.
Pure CIS �CMA Obtained as above is racemised to IR CIS-CMA isomer
using an optically active amine via its salt. Salt is neutralized and
Tagros chemicals India Limited
Chapter II 23
purified to obtain pure (+)-IR Cis permethric Acid having high purity
and matching the reported specific rotation IR CIS CMA is treated with
HBr in presence of a catalyst to obtain becisthermic acid (C3-
(DIBROMOVINYL)-2.2.-Dimethyl Cyclopropoane carboxylic acid. It is
purified by selective crystallization in MDC solvent.
Becisthermic acid is treated with SOCl2 in a solvent get Becisthermic
acid chloride. Becisthermic acid chloride is condensed with NaCN AND
m-phenoxy benzaldehyde in a solvent to isolate racethemic
deltamethrin in good yield.
Racemic deltamethrin produced as discussed is epimerized in a solvent
to isolate IR-CIS-α -S epimer, this is further crystallized to get pure
deltamethrin.
Preparation of Cypermethrin
Solution of D.V.Acid chloride and metaphenoxy �benzaldehyde in
hexane reacts with Solution of sodium cyanide in water in the
presence of triethyl benzyl ammonium chloride as catalyst at 30°C to
give Cypermethrin in hexane solution.
The solution is given water wash to remove traces of sodium cyanide
and hexane distilled out of obtains cypermethrin.
The water washes contain sodium cyanide and it is treated with
sodium hypochloride solution to destroy sodium cyanide.
The purities of reactants to be used viz., cypermethric acid chloride,
metaphenoxy benzaldehyde and sodium cyanide will be above 99%.
Tagros chemicals India Limited
Chapter II 24
The purity of cypermethrin obtained will be minimum 92% pure and
the likely associated impurities are listed at the end of the
manufacturing process.
Preparation of Alphamethrin
The cypermethrin prepared using the above mentioned method is
subjected to epimerization at 25°C in the presence of triethylamine in
solvent hexane to obtain alphamethrin. Then it is filtered, dried under
vacuum. Hexane and tea are recovered and recycled.
The purity of Alphamethrin obtained will be minimum 95% pure and
the likely associated impurities are listed at the manufacturing
process.
Preparation of Permethrin
It is prepared by the reaction of D.V.Acid chloride and Phenoxy Benzyl
Alcohol at 45 to 50°C using hexane as the solvent medium. HCl vapour
generated is absorbed in water and sold as by product.
Proposed
At present the hydrolysis of CBN to CBA conversion is done using
concentrated sulfuric acid. It is proposed to replace this with spent HCl
as established based on pilot plant studies. This will completely
eliminate the generation of spent sulfuric acid. Spent ammonium
chloride formed as the by-product is proposed to be processed to get
ammonium chloride by neutralizing the excess HCl by ammonia
followed by distillation.

3.6 NOISE ENVIRONMENT
The physical description of sound concerns its loudness as a function
of frequency. Noise in general is sound, which is composed of many
frequency components of various loudness, distributed over the
audible frequency range. Various noise scales have been introduced to
describe, in a single number, the response of an average human to a
complex sound made up of various frequencies at different loudness
levels. The most common and universally accepted scale is the A
weighted Scale which is measured as dB (A). This is more suitable for
audible range of 20 to 20,000 Hz. The scale has been designed to
weigh various components of noise according to the response of a
human ear. The impact of noise sources on surrounding community
depends on:
Characteristics of noise sources (instantaneous, intermittent or
continuous in nature). It can be observed that steady noise is
not as annoying as one, which is continuously varying in
loudness;
The time of day at which noise occurs, for example high noise
levels at night in residential areas are not acceptable because of
sleep disturbance; and
The location of the noise source, with respect to noise sensitive
landuse, which determines the loudness and period of exposure.
The environmental impact of noise can have several effects varying
from Noise Induced Hearing Loss (NIHL) to annoyance depending on
loudness of noise. The environmental impact assessment of noise from
construction activity, vehicular traffic can be undertaken by taking into
consideration various factors like potential damage to hearing,
physiological responses, annoyance and general community responses.
Tagros Chemicals India Limited
Chapter III 81
Noise survey has been conducted in the study area while covering
zones viz., residential, industrial and commercial. Noise monitoring
has been undertaken for 24 hr at each location.
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
generated by the operation of the proposed distillery unit activities
around it.
The details of sampling locations with respect to the plant site and the
equivalent day night levels are tabulated in Table 3.7 and the sampling

identifying sensitive issues and to take appropriate action by
maintaining �Ecological Homeostasis� in the past and present
development of the region.
3.7.1 Objectives
The objectives of land use studies are:
To determine the present land use pattern
To determine the temporal changes in land use pattern over a
period of ten years or so
To analyze the impacts on land use due to proposed distillery
unit activities in the study area and
To give recommendations for optimizing the future land use
pattern vis-à-vis growth of plant activities in the study area and
its associated impacts.
3.7.2 Methodology
For the study of land use, of secondary data like census data hand
book, regional maps regarding topography, zoning settlement,
industry, forest etc., was referred. The data was collected from
various sources like District census hand book, Revenue records, State
and Central Government offices and Survey of India (SOI) Toposheets,
and also through primary field surveys.
3.8 BIOLOGICAL ENVIRONMENT
3.8.1 Vegetation & Wildlife Impact Analysis
Vegetation & Wildlife are important features of the Environment, and
they present special problems in environmental assessment. Living
things are adapted to their setting and they organized into natural
Tagros Chemicals India Limited
Chapter III 84
groupings or communities, with mutual dependencies among their
members, and they show various responses and sensitivity to outside
influence. The countless life cycle modes, forms and activities of plants
and animals are very important for considering in their assessment.
Most organisms are native to the area in which they are found, but
some may be alien. Retention or removal of natural communities and
their replacement with domestic forms have numerous implications
that must be considered both ecologically and economically.
Biological Environment Assessment
A habitat or an area comprises of different kinds of plants and animals
within its boundary. The distribution of flora and fauna in the given
area represents the biological environment. The biological portion of
the environment includes, what is present in the study area, its values,
its responses to impacts description of community uniqueness, the
dominant species, and an evaluation of rare or endangered species.
Study Area - an Outline
The study area covers a radius of 10 km around factory site. The
entire study area has been divided into 2-circles of 5 km radius and 10
km radius.
Field Monitoring Stations
The field monitoring stations were installed in four different locations
in 5km radius area and another four locations were installed in 5 to 10
km radius area. The bio-diversity studies were carried out in
seventeen transacts points of 10 km radius.
Analysis of Vegetation in 5 km Radius
The study sites falling under the 5km radius are villages (9 sites)
except the site. The vegetation recorded in this radius shows a
Tagros Chemicals India Limited
Chapter III 85
dominance of prosopis Juliflora, Cassia auriculata, Azadirachra indica
and Cocos nucifera.
Analysis of Vegetation in 10 km Radius
In the 10km radius, the vegetation analysis was carried out in 8-study
site.
The vegetation in this area shows dominance of Mangifera
indica,Anacardium occidentale,Delonix regia, Casuaraina equisetifolia,
ficus bengaliensis, Eucalyptuslaceolatus, Tamarindus indicus, Borassus
flaellifer, Cocos nucifera, Acacia nilotica, Prosophis juliaflora, Polyalthia
longifolia,Pongamia pinnata, Cassia occidentalis,Achyranthus aspera,
Calotrophis gigatean, Cassia auntrculata, Datura metal, Fuphorbia
antiquorium, Oryza sativa,Arachis hypozia, Hibiscus rosa sinensis,
Tribulus terrestris and few species of grasses like Cyprus sps.
Fauna Assessment
The animal life (fauna) of an area is dependent upon the vegetation,
and there are countless relationships between the species composing
of an animal community. Fauna assessment involves more problems
than flora assessment by virtue of the greater variety animal types,
their mobility and behavior. Fauna assessment provides a basis for
determining relative abundance and evaluating commonness or rarity
of each species encountered.
In the study area, the animal survey was conducted in all the sampling
sites along with the plants. The study includes survey of the animal
communities such as insects, Lesser sardines, Perches, Leiagnathus,
squirrel, dogs, cats, goats, mollusks, fishes, reptiles, birds and
mammals.

facilities, the productivity of land is moderate. Irrigation is mainly
dependent on ground water and rain. The major crops include cotton
and other rain fed food grains.
3.9.5 Occupation
"Work" has been defined as participation in any economically
productive activity. Such participation may be physical or mental.
Persons on leave and training are also treated as workers. However
rent receivers and pensioners were not treated as workers.
3.9.6 Workers
Main workers are those, who work for a major part of the year. Main
activity of a person who was engaged in more than one activity are
reckoned in terms of time disposition.
Main workers are classified into 3 categories viz., Cultivators,
Agricultural Labourers, and Other Workers. The worker details are
given in Table 3.9.
The person who is engaged either as employer, single worker or family
worker in cultivation of land owned is termed as cultivators.
Persons working in other�s land for wages or share in the yield have
been treated as "Agricultural Labourers".
3.9.7 Others
All workers i.e. those who have engaged in some economic activity
during the last one year, who are not cultivators or agricultural
Labours are other workers. This type of workers that come under this

4.0 IMPACT ANALYSIS
4.1 PREAMBLE
The predictions of worst possible impact scenario along with baseline
status of environment helps in identification of appropriate mitigate
measures in the planning stage to minimize environmental damage.
It is therefore necessary to identify the critical likely impacts due to
setting up of this unit for various attributes of environment, if no
pollution control measures are adopted.
Proposed project would create impacts on the environment in two
distinct phases.
1. During construction phase which may be regarded as temporary
or short term.
2. The other during the operational phase, which would have long-
term effects.
The environmental impacts in this study have, as such, been discussed
separately for the construction phase and operational phase of the
industry.
4.2 CONSTRUCTION PHASE
The construction phase impacts are expected to be minimal, as for as
construction of the main units are concerned.
During the construction phase, the following activities among others
are considered to be important towards development of impact.
a) Site preparation
b) Excavation and back filling
c) Piling, cutting and drilling
d) Mixing of concrete and mortar
Tagros Chemicals India Limited
Chapter IV 92
e) Concrete construction
f) Erection of steel structures
g) Road construction
h) Painting and finishing
i) Cleanup operations
j) Landscaping and afforestation
In our industry proper planning work of construction will be engaged,
so that the impact due to construction phase will be very low.
4.2.1 Land Transportation and Construction
Construction does not involve any heavy construction equipment.
Transportation of raw material through trucks may not affect traffic in
the main roads.
4.2.2 Land Use
Presently land is not used for agriculture or any other use. The land
was once used for rain fed agriculture, which has been stopped
permanently for past few years.
4.2.3 Water Resources
Any construction activity will need water for mixing cement mortar and
concrete. The demand at present case will vary from 10 to 20 cubic
metre per day depending on the day to day activity. Average demand
shall be 15 cubic metre per day.
The construction shall take place for two to three months.
4.2.4 Air Quality
Air quality will be disturbed by erosion of soil during earthwork and
masonry work. To avoid unnecessary inconvenience, water will be
sprayed on soil heap.
Tagros Chemicals India Limited
Chapter IV 93
4.2.5 Service System
No service system will be disturbed even if it intends to ship out the
materials in peak hours.
4.2.6 Biological Conditions
The present site is devoid of trees and shrubs. The only vegetation
covered on the land is grass, which will be disturbed and some part
will be lost in construction activity. This could lead to soil erosion.
Hence site without structures will be covered with vegetation.
4.2.7 Transportation System
It may not affect traffic as discussed earlier even if it intends to ship
out the materials in peak hours.
4.2.8 Noise
Noise will be created in the site due to construction activity. Reducing
the activities from 5pm to 9am so as to avoid noise in the evening and
night period will give pleasant feelings to everybody.
4.2.9 Aesthetics
Scenery will be disturbed due to construction activity. This is of less
concern to public as there is no settlement in and around the site.
4.2.10 Community Structure
Community structure will be benefited by generation of employment.
Around 100 jobs will be created for three months during the
construction.
4.2.11 Accident Risk
Accidents may occur during construction which could be avoided with
proper supervision and hiring skilled labour along with proper
planning.
Tagros Chemicals India Limited
Chapter IV 94
4.2.12 Resources
Fuel resource will meet by trucks during construction period.
Purchasing the raw material in nearest place and proper planning of
routes could minimize this. Water resources are conserved by
adopting new techniques with new materials like concrete blocks
instead of bricks, which needs less water compared with later.
The proper schedule of construction will be planned. The
construction work will take about 3 to 4 months.
4.3 OPERATIONAL PHASE
In the operational phase, the important activities contributing to
environmental impacts, either adverse or beneficial are as follows.
a) Material Handling
b) Consumption of Water
c) Consumption of Power
d) Wastewater Discharge and Control
e) Atmosphere Emission
f) Air Pollution Control Measures
g) Employment of Personnel
4.3.1 Land Transportation and Construction
Implementation of the project will improve erodability and soil stability
with revegetation.
4.3.2 Land Use
The proposed activity needs the land, which is inside the same
premises due to the nature of product.
Land Environment will be deteriorated with

b) Change in surface permittivity and grading
Construction of plant and roads will change the natural
characteristic of the surface. Addition of impervious surface could
add to marginal increase in runoff, which in turn could lead to soil
erosion in case that soil is improperly vegetated.
c) Aesthetics
Developing greenbelt inside and outside the industry will give
aesthetics value. The greater lawn in the vacant space will also
give pleasant aesthetics value.
4.3.3 Water Resources
An average of around 472 cu. meter of raw water will be needed per
day. Hence 472 cu.m per day x 30 day per month = 14160
cu.m/month will be consumed. This will be met by water from SIPCOT

5.0 ENVIRONMENTAL MANAGEMENT PLAN
A comprehensive Environmental Management Plan is suggested to
minimize pollution load on air, water, land and socio-economic
environment.
5.1 WASTE MINIMIZATION
The waste minimization forms a part of the Environmental
Management Plan to minimize waste load. The management
commitment is one of the important factors deciding waste
management plan.
5.1.1 Management Commitment
Management initiative, commitment and involvement are key elements
in any waste reduction programme and include activities such as:
Employee awareness and participation
Improved operating procedures
Employee training
Improved scheduling of processes
Employee training, awareness and participation are critically important
and can be problematic aspects of waste minimization programmes.
Total commitment and support of management and employees are
needed for any waste minimization programme to succeed. This
includes the evaluation, implementation and maintenance of
techniques and technologies to minimize waste. It is advised to use
mass balances around the facilities and processes to identify areas
where waste is occurring, perhaps unknowingly. The use of good
process is also recommended.
The technical personnel should continuously educate themselves to
keep abreast of improved waste-reducing, pollution preventing
Tagros Chemicals India Limited

5.10 GREENBELT DEVELOPMENT
5.10.1 Objectives
Greenbelt is a set of rows of trees planted in such a fashion, to create
effective barrier between the plant and the surroundings. The
greenbelt helps to capture the mist emissions and attenuate the noise
levels in the plant and simultaneously improving aesthetics of the plant
site.
5.10.2 Greenbelt Design
The greenbelt development contribute remarkable advantages
especially in pollution abatement process like arresting various
pollution sources like control of mist, fume, noise etc., an increasing
the ecological and aesthetic characteristics of the area. Forests help to
intercept incoming and outgoing radiation. Besides, it helps to block
the harmful effects of heavy precipitation due to soil washout etc.
The filtering capacity of trees for dust is 32 to 80 T/Ha. Noise level
abatement to the tune of about 20-30 dB(A) can be achieved by a
Greenbelt barrier of 50m wide. The project authorities will plant trees
to greenbelt development in peripheral portions and inside vacant
plots of the plant for afforestation. The selection of appropriate plant
species for this purpose is based upon the following criteria.
The plant should be fast growing.
The plant should have thick canopy cover.
Tagros Chemicals India Limited
Chapter V 113
Preferably perennial and evergreen.
Having large leaf area index.
Resistance to specific air pollutant.
Should have maximum height.
Indigenous and should maintain ecological, land and hydrological
balance of the region.
The greenbelt development plan for the particular industry depends on
the following.
Nature and extent of pollution.
Sink capacity of the eco-system.
Climatic factors.
Soil and water quality.
Specific site background.
In any greenbelt development, monoculture is not advisable due to its
climatic factor and other environmental constraints. Greenbelt with
varieties of species is preferred to maintain species diversity, rational
utilization and for maintaining health of the trees.
Well-developed greenbelt will develop a favorable micro-climatic to
support different microorganisms in the soil as a result of which soil
quality will be improved further. In greenbelt bird�s nest may be
introduced to encourage more birds in those areas.
In this unit greenbelt development will be undertaken in all available
areas and also in the earmarked affectation zone, and also along the
roads around the plant and plant infrastructure, etc.
Tall and leafy trees like Azadirachta Indica, Polyalthia, Longifolia,
Pongamia galbrae, etc., will be developed in these areas. Around
administrative office, ornamental varieties like Gulmohar,
Peltaphorum, Jacarandah will be planted with the backdrops of lawns.

Chapter V 114
As far as possible the following guidelines will be considered in
greenbelt development. Shrubs and trees will be planted in encircling
rows within the plant site.
The short trees (10 m height) will be planted in the first two rows and
the tall trees (>10 m) in the outer rows around the purview of the
project site.
Planting of trees in each row will be in staggered pattern.
In the front row, shrubs consisting of Alibizia sp. Peltoforum etc will be
grown.
Since the trunks of the tall trees are generally devoid of foliage, it will
be useful to have shrubs in front of the trees so as to give coverage to
this portion.
Spacing between the trees will be slightly maintained facilitating
effective height of greenbelt.

6.0 ENVIRONMENTAL IMPACT STATEMENT
The impact statement focuses on the study area, viz., 10 kms around
the unit.
The four basic environmental components likely to be affected are air
environment, water environment, land environment and socio-
economic environment. For each of the above components the impacts
are identified, predicted and evaluated through Battle Environmental
Evaluation System using value function graphs, to classify the adverse
and beneficial impacts.
6.1 NOISE ENVIRONMENT
The impact of noise generated from this unit on the general population
is expected to be insignificant.
6.2 WATER ENVIRONMENT
The Effluent from the process is Neutralized and evaporated by
Multiple Effect Evaporator to achieve zero discharge system.
6.3 LAND ENVIRONMENT
There would be a slightly positive impact, as the proposal would
involve expansion of the greenbelt thus improving the land use and
soil chemistry.
6.4 SOCIO-ECONOMIC ENVIRONMENT
The impact of the project would be more on the positive side than
negative. Positive impacts are felt due to increase in employment
opportunities and economic benefits.
