INTRODUCTION
1.1 PURPOSE OF THE REPORT
Environmental management plays a vital role in sustainable development of a country.
Recognizing its importance, the Ministry of Environment and Forest, Government of India
had formulated policies and procedures governing the industrial and other developmental
activities to prevent indiscriminate exploitation of natural resources and to promote
integration of environmental concern in developmental projects.
The Ministry of Environment & Forest has made prior Environmental Clearance (EC) for
certain developmental projects mandatory through its notification issued on 14th September
2006 and its subsequent amendment.
Environmental Impact Assessment (EIA) is systematic process to identifying, predicting,
evaluating and mitigating the biophysical, social and other relevant environmental effects
due to the proposed developmental project. It plays a vital role in providing information for
decision-making on the environmental consequences of proposed projects. It promotes
environmentally sound and sustainable development through the identification
appropriate enhancement and mitigation measures.
The setting up of coal washery unit has both positive and negative impacts on the
environment. The negative impacts include environmental degradation and adverse socio-
economic changes. It is the responsibility of the company to document the associated
positive and negative impacts, so that the attempts can be made to minimize the effects due
to the negative impacts and maximize the benefits due to the positive impacts. In this
regard, Environmental Impact Assessment (EIA) and Environmental Management Plan (EMP)
have been considered as the most important documentation in understanding the
environmental implications and safeguarding the environment.
1.2 IDENTIFICATION OF PROJECT & PROJECT PROPONENT
Coal based power plants will continue to play a leading role in power generation in our
country. About 70% of country’s power is generated from coal-based power plants. The
quality of the coal plays an important role in the environmental aspects of a power plant.

Change in Technology [Dry to Wet]
EIA report – Chapter 1 1.2
The quality of Indian coal is mainly attributed to its origin. Due to drift origin of Indian coal,
inorganic impurities are intimately mixed in the coal matrix, resulting in difficult
beneficiation characteristics. Over 200 million tonnes of coal reach the consumers with ash
content averaging 40 percent as per the CPCB report (Clean Coal Initiatives June 2000).
Following are the Grades of coal:
GCV range
Grade Gross Calorific Value (GCV Bands) (K. Cal/Kg)
G 1 Exceeding 7000
G 2 Exceeding 6700 & not exceeding 7000
G 3 Exceeding 6400 & not exceeding 6700
G 4 Exceeding 6100 & not exceeding 6400
G 5 Exceeding 5800 & not exceeding 6100
G 6 Exceeding 5500 & not exceeding 5800
G 7 Exceeding 5200 & not exceeding 5500
G 8 Exceeding 4900 & not exceeding 5200
G 9 Exceeding 4600 & not exceeding 4900
G 10 Exceeding 4300 & not exceeding 4600
G 11 Exceeding 4000 & not exceeding 4300
G 12 Exceeding 3700 & not exceeding 4000
G 13 Exceeding 3400 & not exceeding 3700
G 14 Exceeding 3100 & not exceeding 3400
G 15 Exceeding 2800 & not exceeding 3100
G 16 Exceeding 2500 & not exceeding 2800
G 17 Exceeding 2200 & not exceeding 2500
High ash content in the coal supplied to the power plants not only poses environmental
problems but also results in poor plant performance and high cost for Operation &
Maintenance and ash disposal. Based on review undertaken by MoEF, use of
beneficiated/blended coal containing ash not more than 34 percent in power plants was
stipulated as mentioned below (Ref: GSR 560 (E) & GSR 378 (E) dated 19th September 1997
and 30th June 1998):
Benefits of Used Washed Coal
➢ Increased generation efficiency, mainly due to the reduction in energy loss as inert
material passes through the combustion process.
➢ Increased plant availability.
➢ Reduced investment costs.
Hind Energy & Coal Beneficiation (India) Ltd. [Hindadih]
Change in Technology [Dry to Wet]
EIA report – Chapter 1 1.3
➢ Reduced operation and maintenance (O&M) costs due to less wear and reduced
costs for fuel and ash handling.
➢ Energy conservation in the transportation sector and lower transportation costs.
➢ Less impurities and improved coal quality.
➢ Reduced load on the air pollution control system; and
➢ Reduction in the amount of solid waste that has to be disposed off.

1.3.3 LOCATION OF THE PROJECT
Hind Energy & Coal Beneficiation (India) Ltd. is an existing coal washery at Village Hindadih,
Tehsil Masturi, District Bilaspur, Chhattisgarh. It is proposed for in change in technology in
the existing plant i.e. from 2.4 MTPA DRY type coal washery to 2.4 MTPA WET type coal
washery.
1.3.4 IMPORTANCE OF PROJECT
There is a lot of demand for washed coal, as it reduces the ash generation and thereby
contributing for better environment in industries such as sponge iron, power plants.
• The existing Dry process has limited scope for ash reduction.
• The misplacement of good quality coal as Rotary Discard is high if some good quality
coal is not broken inside Rotary Breaker and report to Rotary Discard. This in turn leads
to loss of yield.
Hind Energy & Coal Beneficiation (India) Ltd. [Hindadih]
Change in Technology [Dry to Wet]
EIA report – Chapter 1 1.6
• Smaller pieces of stones and shales report to the sized coal fraction leading to higher
ash in beneficiated coal and as a result the dry process is not able to maintain consistent
product quality.
• To overcome these problems enumerated above, it has been proposed to change the
beneficiation process from existing dry circuit (2.4 MTPA) to wet process (2.4 MTPA)
with Heavy Media process.
• In various tender pre-qualification technical requirement, it is clearly mentioned that
bidder should have its own coal beneficiation plant using wet technology i.e. Heavy
Media Cyclone / Heavy Media Bath.
• At present the quality of ROM coal is deteriorating day by day and in future we shall not
be able to fulfill the required ash quality to the customers.
The Heavy Media process will have the following advantages over the dry process:
• Maximum ash reduction can be achieved.
• Heavy Media process is ideally suited to treat high ash Indian Coal with high Near
Gravity Material (NGM).
• The process is capable of achieving low misplacement of good coal to rejects as well as
rejects to beneficiated product.
Technological Options
Cleaner production technologies are being used / practiced in coal washeries in India, as pre-
combustion clean coal technology, mainly focus on cleaning of coal by removing ash from
coal.
Earlier only coking coal was being washed because steel making needs coking coal of ash of
17 to 18%. The raw coal ash in Indian coking coal varies from 25 to 30%. Now-a-days,
Ministry of Environment & Forests has put restriction on the use of high ash coal in power
sectors, which necessitated priority to wash non-coking coal also.
The choice of process equipment involved in coal washing depends on factors such as the
type of coal being treated; the market requirement and the economics Continuous research
and development efforts, including trial and adoption of latest equipment/ technology are
being done.

PROJECT DESCRIPTION
2.1 TYPE OF PROJECT
Hind Energy & Coal Beneficiation (India) Ltd. is an existing coal washery at Village Hindadih,
Tehsil Masturi, District Bilaspur, Chhattisgarh. It is proposed for change in technology in the
existing plant i.e. from 2.4 MTPA DRY type coal washery to 2.4 MTPA WET type coal washery.
Proposed change in technology will be carried out in the existing plant premises. Total cost of
the proposed project (i.e. for Change in technology) is Rs.12.00 Crores.
2.2 NEED FOR THE PROJECT
• The existing Dry process has limited scope for ash reduction.
• The misplacement of good quality coal as Rotary Discard is high if some good quality coal
is not broken inside Rotary Breaker and report to Rotary Discard. This in turn leads to loss
of yield.
• Smaller pieces of stones and shales report to the sized coal fraction leading to higher ash
in beneficiated coal and as a result the dry process is not able to maintain consistent
product quality.
• To overcome these problems enumerated above, it has been proposed to change the
beneficiation process from existing dry circuit (2.4 MTPA) to wet process (2.4 MTPA) with
Heavy Media process.
• In various tender pre-qualification technical requirement, it is clearly mentioned that
bidder should have its own coal beneficiation plant using wet technology i.e. Heavy
Media Cyclone / Heavy Media Bath.
• At present the quality of ROM coal is deteriorating day by day and in future we shall not
be able to fulfill the required ash quality to the customers.
The Heavy Media process will have the following advantages over the dry process:
• Maximum ash reduction can be achieved.
• Heavy Media process is ideally suited to treat high ash Indian Coal with high Near Gravity
Material (NGM).

EIA report – Chapter 2 2.2
• The process is capable of achieving low misplacement of good coal to rejects as well as
rejects to beneficiated product.
As per MOEF vide Notification GSR 560 (E) & GSR 378 (E) dated 19th September 1997 and 30th
June 1998, use of beneficiated / blended coal containing ash not more than 34 percent in
power plants was stipulated for:
• Power plants located beyond 1000 kms from pit head.
• Power plants located in critically polluted areas, urban areas and in ecologically
sensitive areas.
Benefits of Using Washed Coal
• Increased generation efficiency, mainly due to the reduction in energy loss as inert
material passes through the combustion process.
• Increased plant viability.
• Reduced investment costs.
• Reduced operation and maintenance (O&M) costs due to less wear and reduced costs
for fuel and ash handling
• Energy conservation in the transportation sector and lower transportation costs
• Less impurities and improved coal quality
• Reduced load on the air pollution control system; and
• Reduction in the amount of ash that has to be disposed off
Technological Options
Clean coal technologies are being practiced in coal washeries in India, as pre-combustion
clean coal technology, mainly focus on cleaning of coal by removing ash from coal.
Earlier only coking coal was being washed because steel making needs coking coal of ash of
17 to 18%. The raw coal ash in Indian coking coal varies from 25 to 30%. Now-a-days, Ministry
of Environment, Forests & Climate Change has put restriction on the use of high ash coal in
power sectors, which necessitated priority to wash non-coking coal also.

2.9.3 PROCESS OF COAL WASHERY [Gen. TOR # v]
• Sized Raw Coal [(-) 50 mm] from crushing and screening plant shall be transported to
an intermediate storage bunker.
• From the intermediate storage bunker, sized raw coal will be fed to the Washing Plant
building through belt conveyor. The sized raw coal will be fed into a Banana Screen.
• The first part of Banana Screen will dry screen raw coal at 8 mm to separate (–)8 mm
fraction which will be taken to a ground dump and will be mixed with washed coal.
The second part of the banana screen will wet screen the raw coal at (–)1 mm for
desliming.
• The deslimed coal [coarser fraction of (-)50 (+)1mm] goes to the HM Bath / HM
Cyclone process. The magnetite media of required specific gravity will be added in the
heavy media process to get mixed with the coal.
• The HM Bath / HM Cyclone will have overflow and underflow. The washed coal along
with magnetite media will be received as overflow, from the HM Bath / HM Cyclone
and will be fed to a set of washed coal sieve bend and Washed Coal Drain & Rinsing
Screen.
• The Magnetite media separated through sieve bend and first part of the screen and
will be collected in the screen’s dense under pans. The same will be circulated back to
the system.
• The carried away magnetite with the coal particles are removed by water spraying in
the discharge part of the screens.
• The magnetite removed from coal by water spraying will be collected in the dilute
catch pan of screen as dilute media. The magnetite from dilute media will be
recovered through Wet Drum Magnetic Separator.
• The washed coal collected at discharge end of screen will then be transported to
storage bunker through belt conveyor.
• The reject from the HM Bath / HM Cyclone will be fed to a drain and rinsing screen to
take out the media and then transported to the bunker through belt conveyor.
• The underflow from desliming screen collected in the fine coal sump will be pumped
to a back to classifying cyclone. The underflow of classifying cyclone will be dewatered
in High Frequency screen.

For measurement of Ambient Noise level in the Study area, a Digital Sound Level Meter
(Make & Model: Lutron SL-4001) was used. The instrument was calibrated with a
Standard Acoustic calibrator before using in the field. The measurements were carried
out continuously for the 24-hour period to obtain hourly equivalent sound pressure level,
1 hour Leq. From these values, day and night time as well as 24-hour Leq values were
also calculated. The Leq is the equivalent continuous sound level, which is equivalent to
the same sound energy as the fluctuating sound measured in the same period.

All the parameters in the water samples collected are in confirmity with BIS: 2296
3.4.2 GROUND WATER QUALITY ANALYSIS
The ground water samples have been collected and analyzed for various parameters like
pH, Suspended Solids, Total Dissolved Solids, Temperature, Total Hardness, Calcium
Phenolic compounds, Heavy metals etc. and is compared with the standards to know the
water quality. Selection of sampling locations will be generally done based on the
following factors:
• Representation of project site.
• Topography
• Industrial Areas
• Residential areas
• Agricultural Activity
Eight numbers of ground water samples from bore wells were collected from the near by
villages to assess ground water quality impacts. The ground water sampling locations and
their distances from the project site are shown in Table No. 3.4.3. These water samples
are analyzed for various parameters as per IS: 10500. The ground water characteristics
were shown in Table Nos. 3.4.4 to 3.4.11. The Ground water sampling stations are shown

3.5 LAND ENVIRONMENT
3.5.1 HYDROGEOLOGY OF THE STUDY AREA
A detailed Hydrogeological Study has been carried for proposed project and same is
enclosed as Appendix – 1. The main observations and finding of the study are as follows:
i. The annual normal rainfall in the area is 1343 mm, which constitute 87 % monsoon
rainfall (1170.8 mm). The average annual rainfall of the district is 1082 mm (Source:
CGWB).
ii. The three major Cherty shale & dolomite aquifer system developed in the area are given
below:
• Unconfined aquifer having depth range of 5 to 30 m.
• Semi-confined aquifer having depth range of 30 to 70 m.
• Confined aquifer in the depth range of 70 to 150 m.
iii. The average water level in the core zone in pre-monsoon and post-monsoon is 8.25
mbgl and 0.56 mbgl respectively. The annual fluctuation is 7.70 m.
iv. The average of water level in the buffer zone in pre-monsoon and in post-monsoon is
8.00 m mbgl and 2.5 mbgl respectively. The annual fluctuation is 5.5 m.
v. Pumping test carried out at plant area to estimate auifer parameters viz T=330 m2/d, K
= 3.30 m/d, Sy = 0.03, Aquifer thickness ˜ 100 m and safe distance ˜120 m.

EIA report – Chapter 3 3.33
vi. The groundwater flow direction is North to South and South to North toward the Lilagar
Nadi. The general groundwater flow is following the path of the Lilagar Nadi. There is
confluence of hydraulic gradient towards the river in the buffer zone.
vii. During pumping, there will be induced infiltration due to withdrawal of water from the
system and creation of infiltration zone. The reduction in surface flow will be 0.013
MCM. The induced infiltration in post-pumping will increase groundwater recharge to
the tune of 0.011 MCM.
viii. The water table in the buffer zone is in the range of 295 m amsl to 245 m amsl. The
average hydraulic gradient of ground water flow is 6.86 x 10-3. In the core zone water
table is in between 280 and 275m amsl.
ix. The project area constitutes Limestone, Cherty shale & dolomite, a potential aquifer to
sustain six tubewells at a discharge rate of 9.0 m3/hr for 12 hr pumping in a day to yield
648 m3/day groundwater for existing washery use. The safe distance between two
tubewells will be 120 m.
x. The groundwater resource estimation for 10 km buffer zone on annual basis has been
done following the GWRE 2011 guidelines.
Gross recharge due to rainfall - 51.40 MCM Natural discharge - 2.57 MCM Net groundwater available - 48.83 MCM Annual ground water draft - 15.45 MCM Allocation for next 25 years - 3.8 MCM Groundwater balance - 29.58 MCM The stage of groundwater development - 32% Category of groundwater development - Safe
xi. The additional surface water withdrawal of 500 m3/day for the proposed washery will
cause draft of 0.17 MCM. There will not be any further ground water withdrawal for
proposed washery thus the area will remain under the safe category on groundwater
resources consideration. However, the Masturi block comes under safe zone as per
CGWA estimation.
xii. The water quality of tube wells located within the project area and buffer zone are well
within the permissible limits except magnesium hardness in higher side. The washery
will operate under the zero-discharge concept. There will be a sedimentation tank for
Hind Energy & Coal Beneficiation (India) Ltd. [Hindadih]
Change in Technology [Dry to Wet]
EIA report – Chapter 3 3.34
reuse of waste water. There will not be any ground water pollution due to proposed
washery activity.
xiii. Rain water harvesting have been done. It is found that due to shallow water level in post
monsoon period and good infiltration rate there will be rejection of rainwater
harvesting in the project area. However, it is planned to recharge 0.033 MCM m3/y in
Plant area.
xiv. As the area falls under the safe category as per CGWA and the total abstraction of
groundwater is 583 m3/day, the Central Ground Water Authority has issued permission
to abstract ground water with Rain Water Harvesting scheme to be implemented.
xv. The surface water resource availability at Bhawaradih Anycut have been estimated to
the tune of 1.56 MCM/year. The requirement of washery plant is 0.17 MCM/year, which
accounts only 11 % of total availability. Thus, there is apple water available at Anycut.
The daily water availability is also estimated in the range of 153900 to 470 m/day.
Whereas the requirement of plant is only 500m3/day. The status of water have also
been checked and concluded that there is surplus water available at Anycut through of
the year except in the month of May where there will be shortfall of 30 m /day. The
proponent will make necessary rainwater storage capacity of 1000m3 in the plant area
to overcome shortfall. The study have also done to investigate the impact of surface
water withdrawal from Anycut on downstream users. The study confirm that area is
under canal command of Khutaghat Dam. Further the observation of Hydrographic
Network station No. W-11, located at Bhawaradih village, exhibit depth to water level in
premonsoon period is 3.28 m below ground level and 0.62 m below ground level in post
monsoon period. Incase water is not withdrawn from the Anycut there will be water
logging in the agriculture field which lead to reduction in crop yield. The downstream
water of Anycut is allowed to flow and confluence into Lilagar Nadi at the distance of
500 m due south.
The Hydrological study conclude that there is a sufficient surface water available at Anycut
to meet additional water requirement to plant. There will not be any adverse impact of
surface water withdrawal on downstream computing users. The area under study is in
canal command having ground water recharge through return flow. The radius of
influence due to pumping of ground water is well within plant area due to cyclic ground
water recharge observed in piezometer and hydrographic network stations. It is concluded
Hind Energy & Coal Beneficiation (India) Ltd. [Hindadih]

EIA report – Chapter 4 4.13
The model was run for ascertaining the areas where we could get the noise levels of 35, 45,
50, 55, 60, 65 and considering the other noise generating sources from the proposed project.
Silencers are provided to the DG Sets. Crusher are inside a covered shed. All machinery are
be manufactured keeping in view of the MOEF&CC/OSHA standards on Noise levels. The
Ambient Noise levels are within the standards prescribed by MoEF&CC and same will be
maintained in the present proposal also.
4.4.2 PREDICTION OF IMPACTS ON COMMUNITY
A day and Night sound pressure level, Ldn is often used to describe the community noise
exposure which includes 10 dBA night time penalties. As the nearest human settlement is
about 0.5 Kms. from the plant, the impact of noise on general population would be
insignificant.
As per the WHO recommendation, there is no identified risk and damage of hearing due to
the noise levels (Leq = 8 hours) less than 75 dBA. Most of the international damage risk
criteria for hearing loss permit (Leq = 12 hours) upto 87 dBA. Further, WHO recommendation
on community noise annoyance, permits day time out door noise levels of 55 dBA. Leq and
night time outdoor noise level of 45 dBA leq to meet sleep criteria i.e. Leq (24 hours) = 52.2.
dBA and Ldn = 5.5 dBA.
4.4.3 PREDICTION OF IMPACT ON OCCUPATIONAL HEALTH
The damage risk criteria as enforced by OSHA (Occupation Safety and Health Administration)
to reduce hearing loss, stipulates that noise level upto 85 dBA are acceptable for 8 hour
working shift per day. Plant authorities are providing ear plugs to the employees & is being
enforced to be used by the employees and same will be maintained in the present proposal
also.
4.4.4 IMPACT ON HABITATION, FLORA & FAUNA DUE TO NOISE LEVELS DUE TO THE PROJECT
There are no National Parks / Sanctuaries / Migratory route for birds / Tiger reserves within
10 Km. radius of the proposed project site. The major noise emanating equipment are
Crushers & DG sets. The noise levels are being maintained by providing and maintaining thick
greenbelt reducing the exposure time of workers to the higher noise levels. All transfer

points, cleats are lined with rubber lining so that the noise levels are reduced. Hence there
will not be any impact on environment due to Noise generated from the proposed project.
4.5 PREDICTION OF IMPACTS ON LAND ENVIRONMENT
4.5.1 POSSIBLE IMPACT ON GROUNDWATER & MITIGATION
IMPACTS MITIGATION MEASURES PROPOSED
Impact on Groundwater Table
Water required for the proposed will be sourced from Lilagarh river (Bhawradih Anicut). The water after washing coal should be allowed to flow through a series of settling ponds designed from higher elevation to lower elevation and collected in sump/pond/tank which can be reutilized for the process. The design and construction of drainage system should be in consultation with a civil engineer. The drawl of groundwater should be planned from different extractions viz. tube wells following spacing norms as per WALTA Act and time of pumping should be synchronized based on the requirement. Rain water harvesting structures are being constructed in consultation with Central Ground Water Board and this will help in augmenting the ground water table. Hence there will not be any adverse impact on Groundwater table due to the proposed project.
Impact on Surface water body
Water required for the proposed will be sourced from Lilagarh river (Bhawradih Anicut). Conveyors, transfer points etc. are provided with enclosures in the existing plant and same will be continued in the present proposal. Closed loop water system is being maintained in the existing plant same practice will be maintained in the present proposal also. There will not be any waste water generation from process. Middlings & rejects are being given to reject based power plants and same practice will be continued in the present proposal. Hence there will not be any impact on Lilagarh River and its downstream users due to the present proposal.
Groundwater contamination due to coal yard during monsoon
During monsoon season, the problem of coal yard drainage becomes critical due to coal particles and dust in the yard. To take care of this problem, the entire coal storage yard will be provided with separate drains, which will lead to a separate sump of adequate capacity. There all the coal particles will settle at bottom

ADDITIONAL STUDIES 7.1 RISK ASSESSMENT
7.1.1 INTRODUCTION
Risk analysis deals with the identification and quantification of risks, the plant equivalent and
personnel are exposed to, due to accidents resulting from the hazards present in the factory.
Hazard analysis involves the identification and quantification of the various hazards that are
likely to occur in the factory.
The various hazard analysis techniques that may be applied are Hazard and Operability
(HAZOP) studies, Fault - Tree Analysis (FTA), event –tree analysis and, failure and effects
mode analysis.
Risk analysis follows an extensive hazard analysis. It involves the identification and
assessment of risks the neighbouring populations are exposed to as result of hazard present.
This requires a through knowledge of failure probability, credible accident scenario,
vulnerability of populations etc. Much of this information is difficult to get or generate.
Consequently, the risk analysis is often confined to maximum creditable accident studies.
7.1.2 SCOPE OF THE STUDY
The scope of work is to carry out risk analysis for the proposed plant covering all the
hazardous chemicals to be handled and stored at the plant.
The risk assessment study will cover following aspects:
➢ Selection of credible scenarios
➢ Consequences Analysis of selected accidents scenarios both onsite and off-site
On-site
• Emission/spillage etc. from storage & handling
• Exposure to fugitive dust, noise, and other emissions
• Housekeeping practices requiring contact with solid and liquid wastes

7.1.4 METHODOLOGY OF MCA ANALYSIS
The MCA Analysis involved ordering and ranking of various sections in terms of potential
vulnerability. The following steps were involved in MCA Analysis.
• Preparation of an inventory of major storages and rank them on the basis of their hazard
properties.
• Identification of potentially hazardous storage sections and representative failure cases
from the vessels and the pipelines.
• Visualisation of chemical release scenarios.
• Effect and damage calculation from the release cases through mathematical modeling.
• Inventory Analysis and Fire & Explosion and Toxicity Index (FETI) are the two techniques
employed for hazard identification process.
7.1.5 FIRE & EXPLOSION AND TOXICITY INDEX
The role of Fire & Explosion Index (FEI) aids quantitative hazard identification. The FEI is
calculated by evaluating the loss potential of all the units in the storage area and the
hazardous areas were classified accordingly.
The role of FEI is
• Identification of the equipment/areas that could likely contribute to the creation or
escalation of incident and relatively rank the incidents.
• Quantification of the expected damage of potential fire and explosion incidents.
• Preparation of guidelines for mitigating fire hazards.
The loss potential which could actually be experienced under the most adverse operating
conditions is quantitatively evaluated. The FEI is used for any operation in which a flammable,
combustible or reactive material is stored, handled or processed.
FEI = MF * GPH * SPH
Where MF : Material factor
GPH : General Process Hazard
SPH : Special Process Hazard

ENVIRONMENTAL MANAGEMENT PLAN
10.1 INTRODUCTION [Gen. TOR # iv & xiii]
The major objective and benefit of utilising Environmental Impact Assessment in project
planning stage itself, is to prevent avoidable losses of environmental resources and values
as a result of Environmental Management. Environmental Management includes protection
/ mitigation / enhancement measures as well as suggesting post project monitoring
programme. Environmental management may suggest revision of project site or operation
to avoid adverse impacts or more often additional project operations may have to be
incorporated in the conventional operation.
The industrial development in the study area needs to be intertwined with judicious
utilisation of non-renewable resources of the study area and with in the limits of
permissible assimilative capacity. The assimilative capacity of the study area is the
maximum amount of pollution load that can be discharged in the environment without
affecting the designated use and is governed by dilution, dispersion, and removal due to
physico-chemical and biological processes. The Environment Management Plant (EMP) is
required to ensure sustainable development in the study area of the proposed plant site,
hence it needs to be an all encompassive plan for which the proposed industry,
Government, Regulating agencies like Pollution Control Board working in the region and
more importantly the affected population of the study area need to extend their
cooperation and contribution.
It has been evaluated that the study area has not been affected adversely and is likely to
get new economical fillip.
The affected environmental attributes in the region are air quality, water quality, soil, land
use, ecology and public health.

maintained in the existing plant and same practice will be following in the present proposal
also. Hence there will not be any impact on land environment due to the proposed project.
The solid waste generated from the existing plant is being utilized / disposed as per norms
Hind Energy & Coal Beneficiation (India) Ltd. [Hindadih]
Change in Technology [Dry to Wet]
EIA report – Chapter 10 10.10
and same practice will be followed in the present proposal also. Hence there will not be any
adverse impact on land environment due to the solid waste generated from the proposed
project activities. 1/3 of the Greenbelt i.e. 9.1 Acres is developed in the Plant area will have
positive impact on land environment. Lawn is developed in open areas & at admin building
and other areas to reduce the soil erosion within the premises.
A brief plan for soil conservation is given below for present proposal:
1. Rain water coming down from the nearby hill will be diverted in to the natural drain.
2. The 10 wide greenbelt on all sides shall be at least 30 to 50 Cm lower than the adjacent
ground. Along the gradient, the greenbelt shall be divided in to a number of plots by
small bunds filled with rocks. There shall be a gradient of about 30 cm from plot to plot.
All the storm water flows in to the plots of greenbelt from different points and then it
flows from one plot another down below. It looks like a miniature terrace cultivation.
Ultimately, the surplus water will flow in to an onsite pond for percolation and settling.
The soil structure is such that most of the water will sink in to ground within a few days.
If there is any water in the rain water collection pond, it will be used for plantations,
gardening, and dust suppression. When the pond becomes dry, the silt and soil particles
settled at the bottom shall be taken out and spread thinly over the soil in the greenbelt.
Recommendations
Land scaping is done around the Administrative building, raw material storage areas, etc.
and recommended to continue the same practice.
10.3.6 MEASURES FOR IMPROVEMENT OF ECOLOGY
There are no Wild life sanctuaries, Bird sanctuaries, National Parks within 10 Km. radius of
the plant. No significant vegetation occurs in and around the project site. No significant
fauna exists in the area. Hence there will not be any adverse impact on flora & fauna due to
the proposed project.
Recommendations
➢ Plantation programme is being carried out in several areas. They include plantation,
along the internal and external roads and along the administrative buildings and the
stacking yards.
➢ People should be educated and trained in social forestry activities by local
governmental and non-governmental organizations.

• The average rainfall and the land area have been taken up for the estimation of runoff
for the prediction from the project site.
• As the vacant exposed land would be converted in to built up land, the natural
recharge that had taken place during the pre-construction period would not occur and
hence there would be meager infiltration.
• The losses such as, Percolation, evaporation and other unforeseen loses have been
considered.
The following is the Plan for rain water harvesting measure at plant site.
Total Area = 85064.9 M2
Average annual rainfall = 1082 mm
Quantum of Rain water that can be harvested from the premises
a) Average annual rainfall = 1.082 m
b) Runoff co-efficient
Runoff co-efficient for Roof area = 90%
Runoff co-efficient for Roads and Paved area = 80%
Runoff co-efficient for Open area = 40%
Runoff co-efficient for Green belt area = 20%

10.4 POST PROJECT MONITORING STRATEGY
The monitoring of various environmental parameters is necessary as part of the
environmental protection measures. Monitoring is an important feature because the
efficiency of control measures can only be determined by monitoring. A comprehensive
monitoring programme is given under. PM2.5, PM10, SO2 and NOX are monitored as per
Ministry notification vide G.S.R. No. 826(E) dated 16th November, 2009.
Locations and frequency of monitoring as per the guidelines of CECB and MoEF&CC are
tabulated below:
