1.0 INTRODUCTION
Human environment can be defined as the interaction of the surroundings in which he
lives. Thus, the air he breathes, the water he drinks, the temperature in which he survives
and in fact all other items which have a direct bearing on human existence can be
classified as environment. Usually the most important and universally accepted
components of this complex system are the land, which gives him food, the water bodies
which satisfy his thirst and the atmosphere which provides him air to breath. Any
imbalance in any of these has a direct detrimental effect on the physical and mental
health of man.
Today one hears of contamination of the atmosphere due to nuclear mishaps, pollution of
land due to nuclear fallout and fouling natural waters by indiscriminate waste discharge
by industries. The rapid deterioration of environment has not only jolted the developed
and developing countries in action, but sounded a clear warning bell for the
underdeveloped countries as well. The message is clear – “Either preserve the
environment and prosper or pollute it and perish”.
Earlier, the assessment of the projects was done on Technical feasibility reports and Cost-
Benefit-Ratio which mainly considered financial & technical resources. But no
consideration was given to the environment protection in this evaluation and these flaws
became apparent with continuous deterioration of environment. Thus in order to have
more realistic evaluation, and keeping in view the deteriorating conditions, another
dimension was added which is now called as “Environmental Impact Assessment”
(E.I.A.). This forms an integral part of the project and is taken into account while
appraising the project at different stages. Thus in the new comprehensive approach all
considerations like, Technical, Financial & Environmental are given due weightage.
M/S HIMALAYA ALKALIES& CHEMICALS LTD (Formerly SNJ Chemex (P)
Limited) have its corporate office at AP-2A, PITAMPURA, New Delhi, is formed to
setup its new unit in Himachal Pradesh. The promoters with its

group companies are engaged in the area of manufacturing and marketing of chemicals.
The company started some 25 years back with the manufacturing of CPW and gradually
developed to become the leading company for the production of CPW in the country.
Their group is one of the biggest consumers of chlorine in its manufacturing facilities at
various locations at Haryana, Punjab & West Bengal. To keep pace with growth of the
company, the management has planned to further diversify the business into
manufacturing of basic chemicals i.e. Caustic soda. This will not only reduce their
dependency on other suppliers of Chlorine but it will also help to consolidate its
production centres at one place. The company proposes to set up 400 MT per day
capacity plant
The plant will be located in village –Johron, Kala Amb, Tehsil Nahan in Dist. Sirmaur in
the state of Himachal Pradesh. The availability of uninterrupted power supply at
competitive rate comparatively with its neighboring states to make an edge over other
manufacturers in the northern India.
The company will use environment friendly, fuel efficient and state of the art technology
for the production of caustic soda. The project will take approximately 18 months to
complete, after the approval from statutory authorities for necessary environmental
clearance.

3.0 BASELINE ENVIRONMENTAL SETTING 3.1 The State
Himachal Pradesh having world’s mightiest mountain ranges is one of the hilly
States situated in the Northern part of India. It is blessed with some of the most
spectacular and beautiful landscapes. It came into being in November, 1966 after
the re-organization of States. Earlier, it was part of the combined State of Punjab.
The various hill towns in the State not only provide visitors reprieve from the
sultring heat of the planes, but offer beautiful scenic sites which are real treat to
the eyes. Kulu and Kangra valleys offer natural beauty which is no less than
Kashmir Valley. Valleys and streams, snow clad mountains and temperate forests
offer tourists and sportsmen all they want.
The total area of the State is about 55,700 sq. km., with a population of more than
60lac. The literacy rate is about 63%. The main fruits / crops in the State are
apple, plum, ginger, peach, potato, forest produce, rice and wheat. The State has
good deposits of minerals like gypsum, lime stone and slate etc.
Earlier the economy of the State mostly depended on tourism and a large number
of tourist sites had been developed by the State. However, after the re-
organization, the State has made big strides in the field of industrialization also.
Industries like Cement, Electronics, Fertilizers, Pharmaceuticals and Liquor can be
found in good number at different places in the State. Hydel Power in the State has
given a big boost to the Industries. A number of Industrial areas have been
developed in the State, where all facilities are provided to the entrepreneurs.
Parwanoo, Barotiwala, Baddi, Paonta Sahib and Raja Ka Bag are some of the
important industrial areas developed by the State in the last two decades.

MEMBRANE CELL TECHNOLOGY:
The most common chlor-alkali process involves the electrolysis
of aqueous sodium chloride (a brine) in a membrane cell. In the membrane cell,
the anode and cathode are separated by an ion-permeable membrane. Saturated
brine is fed to the compartment with the anode (the anolyte). A DC current is
passed through the cell and the NaCl splits into its constituent components. The
membrane passes Na+ ions to the cathode compartment (catholyte), where it forms
sodium hydroxide in solution. The membrane allows only positive ions to pass
through to prevent the chlorine from mixing with the sodium hydroxide. The
chloride ions are oxidised to chlorine gas at the anode, which is collected, purified
and stored. Hydrogen gas and hydroxide ions are formed at the cathode.

thus passed through the RO plant to control its TDS contents and brought it
down below 100ppm and will be recycle back into the plant. Part of this
water will be utilized in gardening and other part of the factory. The effluent
treatment plant is designed such that there will not be any liquid discharge
from the factory.
4.11.2 Solid waste
About 4% solid waste will be generated from the process. The solid waste is non
hazardous. It will be sent to filling low lying area or as per norms of State
Pollution Control Board.
4.11.2 Hazardous waste
The industry will install two no. DG sets of 500KVA capacity each. The Hazardous
wastes generated from the unit, such as used oil from DG Set shall be sold to recyclers.
There are no other hazardous wastes.
4.12 Pollution Control Measures
The main sources of pollution from the unit are discussed as under:
4.12.1 Air Pollution
Emergency Chlorine Scrubber (ECS) System
The emergency chlorine scrubber (ECS) uses extraction fans to collect gas from
all the chlorine-containing plant vents. The gas is then scrubbed with caustic soda
to remove chlorine producing sodium hypochlorite. The reaction is as follows:

The ECS is a safety critical system designed to accommodate chlorine surges
during plant upsets for 10 minutes minimum of full chlorine production. All vents
containing chlorine pass to the ECS system. The concentration of chlorine in the
exit gas from the ECS is monitored and alarmed.
Electrical power to the circulation pumps and extraction fans is backed up by
emergency power from a stand-by emergency diesel generator. A nitrogen ejector
that does not require power for operation further backs up the fans. A caustic
gravity head tank that does not require power for its operation, further backs up
the caustic pumps.
Hypo Tower:
The gases come out of the hypo tower and HCl plant. Well designed scrubbers
keeps the vents prevents any hazardous gases escaping into the atmosphere.
Chlorine and HCl vapors concentration s are kept below the permissible limit ie 5
ppm. Similarly the boiler chimney is designed to prevent the to be in compliance
of pollution norms.
Installation Of Chlorine Sensing Alarm System:
Chlorine alarm system which will sense above 3 mg/nm3 in air will be installed in
CP complex for early warning on action of chlorine control will be received.
Neutralization System: Industry will install a neutralization system where in
un-reacted chlorine gas will be sucked from 08 Nos CP reactors through pressure
regulated valve and neutralized with caustic soda to from sodium hypo-chloride.
Initially chlorine will be supplied in toners but at later it is to be supplied through
pipeline.
Boiler: Industry will install steam boiler of 14TPH capacity. The wood
briquette/Pet coke will use as fuel for boiler. APCD cyclone fallowed by wet
scrubber will be installing with boiler to control emission.

4.12.2 Water Pollution
There will be no generation of waste water from process. The waste water generation from domestic, cooling and boiler blow down shall be used for plantation after treatment.
4.12.3 Noise Pollution
There is no noise producing machineries in the unit. All machines are spread at
different places within the covered sheds. Thus no noise of significant level shall
go out side the working area which may disturb the general noise environment.
DG set installed shall be noise free & with canopy.

5.0 ENVIRONMENT IMPACT ASSESSMENT:
5.1 Present Environment:
Various Environment factors as existing in the project area which possibly could
be affected by the activities have been assessed & identified as below:
(i) Ambient Air
(ii) Water Quality
(iii) Noise
(iv) Land use pattern
(v) Soil and Agricultural
(vi) Demography and socio-economic pattern.
5.2 Probable Impact on Environment:
The above factors will be checked after the implementation of the project to cross
check the probable impact discussed hereunder and remedial measures taken
wherever necessary. Broadly the impacts may be classified in two categories as
under:-
i) Short term - during construction/development stage
ii) Long term - during operational stage.
Both these categories have been considered while predicting and evaluating the
impacts as given herein after:-
5.3 DEVELOPMENT STAGE: - (SHORT TERM)
This is a construction phase of the project and the impacts are temporary due to
construction related activities which are as under:-
i) Air Environment:
There is no point source of air pollution. The only source will be due to
construction and plying of vehicles within unit. Some emission may be
expected from vehicles plying in the area for transportation of material etc.
![Page 24: 1.0 INTRODUCTIONenvironmentclearance.nic.in/writereaddata/Online/TOR/0_0_02_May_2015_1202421971...dependency on other suppliers of Chlorine but it will also help to consolidate its](https://reader033.vdocument.in/reader033/viewer/2022042023/5e7b75a77c5721751a5b030a/html5/thumbnails/24.jpg)
24
Kerosene oil shall be provided to the labour so that they do not burn wood
for cooking etc.
ii) Water Environment :
Requirement of water during construction & machinery foundations will be
about 1.0 m3/day and there will be no waste discharge as the same will be
used completely. However, during monsoon some malba etc may get
washed due to run off from the site. There is a natural ‘nallah’ near the land
which takes the entire run off from the area.
Labour during construction is not very large. Hardly about 50 persons may
be working daily on an average who may be using water for drinking and
bathing etc. Toilet facilities with septic tank will be provided to labour @ 1
toilet for 20 persons who will be used by the labour.
In view of this there is no likelihood of any significant impact on the
general environment of water in the area.
iii) Noise Environment:
Some noise may be expected from the working of the machinery repair
purposes and movement of vehicles. Steps will be taken to reduce its effect
by resorting to staggering of various operations. Even otherwise since
there will not be any large scale machinery, the activity is not likely to have
any significant effect on the over all noise environment.
iv) Land Environment:
The total land area of the project is 1, 90,000 sqm. Natural drainage will
not be disturbed. Solid waste from construction activities will be used
within the premises under roads & refilling. There will not be any
significant impact on land in general.
v) Socio Economic:
The project does not involve any displacement of population or
rehabilitation of any kind. Rather it will provide employment to local
people in the shape of additional man power required for the units, & will
![Page 25: 1.0 INTRODUCTIONenvironmentclearance.nic.in/writereaddata/Online/TOR/0_0_02_May_2015_1202421971...dependency on other suppliers of Chlorine but it will also help to consolidate its](https://reader033.vdocument.in/reader033/viewer/2022042023/5e7b75a77c5721751a5b030a/html5/thumbnails/25.jpg)
25
and boost the economy of the area. It will have some positive impact,
although not to a large extent.
5.4 OPERATIONAL STAGE: - (LONG TERM)
After completion, when the unit starts production, the operational impacts
on the various parameters are considered as under:-
i) Ambient Air Environment:
There is only one source of likely pollution which is vapours of Acid/alkali
mist from the manufacturing process. All the processes are closed circuits
as such emissions to the open atmosphere will be minimum, however,
APCD, Alkali Scrubber will be provided at the exit point to neutralize the
acid mist.
ii) Water Environment:
Alkaline Effluent System:
Effluent from alkaline process area catchments drains to trenches which
channel effluent to the alkaline effluent sump. From here, alkaline effluent
is transferred to the alkaline effluent tank where it is mixed and neutralized
using HCl and NaOH to achieve a pH in the range of 6.5 and 10.5.
As these neutralisation reactions have the potential to liberate chlorine gas
under certain conditions, the alkaline effluent tank is operated under light
suction, venting to the emergency chlorine scrubber (ECS) where any
chlorine gas present is removed.
Acidic Effluent System:
The acid effluent system is quite similar to the alkaline effluent system
discussed above. Effluent from acid process areas drains to the acid effluent
trench, then to the acid effluent pit from where it is pumped to the acid
effluent tank. The acid effluent tank is used to mix and neutralise effluent
using HCl and NaOH to achieve a pH in the range of 6.5 and 10.5.
Rainfall data shows that the area is having adequate rainfall. The guidelines
for Rain Water Harvesting and Artificial Recharge of Ground Water issued

26
by the Central Ground Water Authority will be followed.
iii) Land Environment:
The Project is coming in the agriculture land. Thus there will not be any
significant adverse effect on the existing general land environment with the
coming up of the project.
iv) Noise Environment:
There will be no noise producing machinery or equipment except DG Set
which will be placed in acoustic room, causing least disturbance in the
area. There is no likelihood of any significant change in noise environment.
v) Socio Economic Pattern
The project will provide employment to local people in the field of running
plants and maintenance of machinery, APCD & security etc. Thus it will
have positive effect on the employment potential in the area.

6.0 ENVIRONMENTAL MANAGEMENT PLAN: 6.1 General
Environment Management Plan (E.M.P) in a project is prepared to mitigate the
possible adverse effect of various activities on the existing environmental factors,
during construction as well as in operational stages, to avoid their deterioration, if
any. It is desirable that necessary steps are taken right from the beginning of the
project to be more effective. As a social and moral obligation on the part of every
body it becomes our bounden duty to leave our environment to the next generation
in a state at least what we inherited from our ancestors, if not in a better condition.
E.M.P. for this project has been prepared keeping in view the existing conditions
and likely changes which may occur due to the proposed project. The
implementation and monitoring of different control measures have also been
covered. These are discussed as under:-
6.2 Air Environment
During construction stage water will be sprinkled on the soil to avoid dust
generation, if any. The debris and unused construction malba shall be removed
immediately for recycling, if any, or for land fill. All vehicles for service
activities at the project site shall be checked for vehicular emission. The agencies
will be asked to keep them within prescribed limits. They will also be asked to
maintain them properly.
During operation phase alkali scrubber shall be provided to neutralize acid mist
from process, to keep it within permissible limits. Cyclone will be provided with
boiler to mitigate air environment. Tree plantation shall be resorted to for further
improving the air environment in general and minimize noise levels, if any.
6.3 Water Environment:
Source of water will be own tube-well. During construction toilet facilities shall
be provided to labour with septic tank. Finally, waste water from the toilets shall
be taken to septic tank through underground delivery system. It will not be thrown
![Page 28: 1.0 INTRODUCTIONenvironmentclearance.nic.in/writereaddata/Online/TOR/0_0_02_May_2015_1202421971...dependency on other suppliers of Chlorine but it will also help to consolidate its](https://reader033.vdocument.in/reader033/viewer/2022042023/5e7b75a77c5721751a5b030a/html5/thumbnails/28.jpg)
28
outside either on land or in any water body. Roof top rain water shall be harvested
and used for ground water recharge to minimize effect of withdrawal of water
from the underground.
6.4 Land Environment:
To avoid erosion of the top soil the development is planned in the shortest possible
time and land-clearing activity shall be kept to the absolute minimum by working
at the specific sites one by one where construction is to take place so as to increase
detention and infiltration. Natural waterways/drainage pattern shall be maintained
by providing culverts where needed. The requirements of sand and aggregates for
the construction works will be met through venders. The land use is thus so
planned that there is minimum adverse impact.
6.5 Solid Waste
The solid waste generated from the construction activities shall be effectively
recycled within the project. The solid waste generation from the process the
process will non toxic/non hazardous. The disposal of solid waste will be as per
norms of State Pollution control Board.
6.6 Noise Environment
During Construction stage “NO HORN” signs will be displayed at prominent
places. The drivers shall be directed not to blow horn unnecessarily. Vehicle owners
will be asked to maintain them in proper condition. During operational stage noise
creating machinery such as blower, ID Fans etc will be housed different places
within closed sheds so as not to disturb the noise level in the area. The DG set shall
be noise free.
6.7 Green Belt:
The main objective of the green belt is to provide a barrier between the source of
pollution and the surrounding areas. The green belt helps to capture the fugitive
emission and to attenuate the noise generated, apart from improving the aesthetics.
Development of green belt and other forms of greenery shall also prevent soil
erosion and washing away of topsoil besides helping in stabilizing the functional

29
ecosystem and further, to make the climate more conducive and to restore water
balance. It is planned that the selected plants will be grown as per normal
horticultural (or forestry) practice and authorities responsible for plantation will
also make sure that adequate provision for watering and protection of the saplings
exists at site. Species of trees shall be selected in consultation with the forest
Department officers. In all about 500 trees & shrubs are proposed to be planted
within the unit premises.
