Socio-Economic Environment:
Socio-economic environment – demographic and related socio-economic data was
collected from district census handbook 2001 to assess socio-economic status of the
study area.
In villages, agriculture dominates the economic scene in the study area. The main
occupation and also the main source of income of the majority of the households in the
area are agriculture and related activities. The percentage of main workers, marginal
workers and non-workers are 30.17 %, 2.47 % and 67.36 % respectively.
The demographic structure of villages of the study area has been studied. The total
population of the study area is 91,882.
ENVIRONMENTAL IMPACT IDENTIFICATION, PREDICTION AND MITIGATION:
The likely impacts due to the proposed project on Air, Water, Noise, Soil/Land, Ecology
and Socio-economic have been identified and evaluated. Based on the significance of
impacts, control measures have been planned.
Air Environment:
1. During Construction
It may be noted that since the industry is going for expansion in the existing land area
utilizing the existing machinery, there shall not be any construction carried out.
Therefore there will be no any adverse impact on the surrounding air quality due to the
proposed expansion.
2. During Operation
The operational activities are usually expected to have long-term impacts on air
quality. Process emissions would be the core sources of air pollutants. Air pollutants
like Asbestos fibre and SPM will arise from process.
EIA FOR M/s. RAMCO INDUSTRIES LIMITED
x
For air pollution control in plant area, four dust collectors (one for Fibre Circuit, second
for Cement Circuit, third for Fly Ash Circuit and fourth for Pulverizer Circuit) have been
attached to the process vents. The whole process is enclosed. Asbestos fibre is added
into process by automatic Bag opening device and later on Water is added so as to
reduce any kind of fibre dispersion into air due to process and handling during
operation phase.
The maximum ground level concentration for pollutants has been predicted for
proposed scenario giving equal concentration contour plots for SPM and Asbestos
Fibre. Ground level concentration was superimposed on existing ambient air quality to
obtain proposed scenario for the purpose of prediction and evaluation of impact of
stack emission on surrounding environment. The results were found within prescribed
limits.
Thus, it can be concluded that there will be no adverse impact on Ambient Air Quality
of the surrounding environment due to proposed expansion project.
Water Environment:
Water Requirement:
1 During Construction
No any construction work is required is to be carried out. Therefore no any water will
be required for construction.
2. During Operation
Water requirement during the operation phase after the said expansion would be
approximately 95 KL/day which consists of 90 KL/day of fresh water and 5 KL/day of
recycled wastewater from process. Water requirement will be met by Narmada water
through Gujarat Infrastructure Limited.
EIA FOR M/s. RAMCO INDUSTRIES LIMITED
xi
Waste Water Generation and Disposal:
There will be no industrial wastewater discharged from the process, since the small
amount of 5 KL/day of wastewater generated will be recycled back into the closed
circuit process.
Domestic effluent will be disposed off through septic tank/ soak pit system.
Thus, it may be concluded that there would be no adverse impact on water
environment due to the proposed expansion of project.
Land Environment:
1. During Construction
The proposed expansion will be carried out in the existing premises utilizing the
existing facilities and machinery. Therefore no any construction work will be carried
out. Thus there will be no any adverse impact on the surrounding land due to
construction.
2. During Operation
The impact of air, water and solid waste pollution on soil causes direct / indirect effect
on soil. During operational phase, since the maximum predicated GLCs of air pollutants
are insignificant, there will be negligible effect on the surrounding soil. The emissions
of pollutants during operation will be effectively controlled. So there will be practically
no effect on the land.
It may be noted that there will be no disposal of effluent on land. So there will be no
adverse effect on land/soil due to wastewater.
All necessary control steps will be provided for handling, storage and disposal of solid
waste generated from the plant. Thus, there will not be any significant impact of solid
waste on soil environment.
EIA FOR M/s. RAMCO INDUSTRIES LIMITED
xii
Noise Environment:
No construction activity will be carried out. Therefore the major source of noise will be
operation phase. Noise will generate due to operation of machinery and pumps.
However, suitable protective equipments will be provided to workers who are exposed
to high sound pressure levels. The occasional noise will be attenuated by the green
belt around the industry.
Hence, There will be no increase in noise level in the study area due to proposed
project.
Socio-Economic Environment:
The existing industrial and development have already made the area an attractive
place for people to move in or return to the area. A change in the demographic profile
is also observed. M/s. Ramco Industries has done various welfare activities for the
surrounding area and villages.
The industry has employed about 116 employees viz. including skilled labour, unskilled
labour and office staff from the local area. After the proposed expansion of the project
there may be few direct & indirect job opportunities.
Local people have been given preference wherever found suitable for all the jobs in the
plant, direct as well as indirect. Economic status of the local people has improved.
Educational, medical and housing facilities in the study area have considerably
improved.
Thus, the proposed expansion of the project will have significant positive impact on the
socio-economic status of the study area.
EIA FOR M/s. RAMCO INDUSTRIES LIMITED

ENVIRONMENTAL MANAGEMENT PLAN:
An Environmental Management Plan has been prepared for mitigation of the adverse
impacts. The Environmental Management Plan describes in brief, the management’s
plan for proper and adequate implementation of treatment and control system for
pollutants and for maintaining the environment. It also includes development of green
belt, proper safety of workers, environmental monitoring plan, rain water harvesting,
Fire protection system and measures etc.
Environmental Monitoring Plan:
Monitoring of environmental factors and constraints will enable us to identify the
changes in the environmental impacts at various locations and application of mitigative
measures. To ensure the effective implementation of the EMP, monitoring of ambient
air quality, stack emissions and noise levels will be carried out as required / specified
by statutory authority.
Green Belt Development:
An existing greenbelt of area of 12,300 m2 has been developed by M/s. Ramco
Industries limited. An additional 4,700 m2 of greenbelt development will take place
during the proposed expansion of the project.
Rainwater Harvesting:
A scheme for rain water harvesting will be adopted by the unit.
EIA FOR M/s. RAMCO INDUSTRIES LIMITED
xiv
CONCLUSION:
No ecological damage will occur.
Negligible impacts will occur on air quality. However, all the necessary air
pollution control measures will be provided.
No adverse impacts will occur on water environment.
Local employment opportunities will increase.
Various other environmental parameters like Forest / National Park / Sanctuary
and Religious / Historical Places will not be affected.
The project will help in reducing the gap of demand and supply of fibre cement
products.
However it may be noted that:
Environmental Management Plan has been formulated to control all the pollutant
parameters and Environmental Management Cell has been set-up to ensure that
these parameters do not exceed the norms set out by the concerned authorities.
Also after the proposed expansion the Environmental Management Cell will take
care of all the pollution control measures.
Overall, the proposed expansion project of M/s. Ramco Industries Ltd. would
have negligible adverse impact on the surrounding environment.
