CHAPTER -1
INTRODUCTION
1.0
GENERAL
Coal is an important infra-structural input and a dominant source of energy in
India accounting for 54% of the country’s primary energy needs. The quality of
coal plays an important role in environmental aspects during its use especially in
power plants. Due to drift origin of Indian coal, ash content is quite high and coal
seams have dirt bands of carbonaceous nature. High ash content in coal causes
environmental pollution apart from reducing plant efficiency and adding the cost
of coal transportation per unit calorific value. Further ash disposal is itself a
difficult task with adverse environmental impacts. The environmental law prohibits
the use of coal having ash more than 34% for use in power plants in critically
polluted area, ecological sensitive area or urban area, or located at distance of
more than 1000 km from pit head. Thus it is imperative that coal is beneficiated
before use not only for value addition but also as environmental mitigation
measures. The coal seams in mines under Bharat Coking Coal Limited have
been found to have coking propensities to different extent and it has been found
by scientific investigation that production of high valued coking coal can be
produced by washing this coal. The outputs or the balance of products comprises
of coking coal with 17-19% ash for use in steel making, middling for use in
thermal power plants and rejects too can be gainfully utilized in power generation
through fluidized bed combustion plants. The augmentation of quality coking coal
will reduce the dependence on import saving huge foreign exchange. In the
backdrop of the above, it was decided in review meeting taken by Minister of
State (Coal) at Kolkata on 11.01.2007 to set up modular washeries of high
capacity for economic washing of available high ash coal in order to supply
improved quality and sized coal to consumers. Bhojudih NLW Washery (2.0
MPTA) is one such washery proposed to be installed on Build, Operate and
Maintain concept with the state of the art technology for right mix of products with
optimized yields.
1.1
BRIEF DESCRIPTION OF THE PROJECT

2.1.2
Type and Need of the Project
Bhojudih Coal Washery of capacity 2.0 MTPA has been proposed to be
set up and it was decided that N/S Tisra OCP (Seam-I, II & III) will be
linked mines for supplying raw coal to proposed washery.
The proposal is for setting up of a new coal washery of 2.0 Mty capacity
covering an area of 15 Ha beside the existing Bhojudih coal washery in
non-coal bearing area of BCCL for beneficiation of raw coal. The proposed
washery will be producing metallurgical coal for steel plants and washed
power coal for power plants. Our country imports metallurgical grade coal
to meet the demand of the same. The metallurgical coal produced by the
washery will not only partly meet the demand but also save foreign
exchange for our country.
2.1.3
Objectives
Washed Coal / Clean Coal from this plant will be linked to different steel
plants, middlings will be linked to thermal power plant and rejects will be
utilized in proposed Fluidized Bed Combustion plant for generation of
power. This Environmental Impact Assessment and Environmental
Management Plan (EIA & EMP) report has been formulated to carry out
beneficiation / washery operation in an eco-friendly manner.

LIFE OF THE PROPOSED WASHERY & CONSTRUCTION
SCHEDULE
The balance lives of the above linked mine of N/S Tisra OCP is about 10.0 years at
their projected capacities. This linked mine will be contributing around 100% of the
total requirement of 2.23 Mty for about 7 years (considering the evacuated quantity
till the washery coming up) whereas the economical life of the washery has been
taken as 18 years. Hence BCCL has to explore to supply similar quality coal from
neighboring mine(s) after exhaustion of the existing mine.
A total period of 18 months has been considered for construction and commissioning
of Bhojudih washery including trial operation and Performance Guarantee Tests
(PGT).

The washery has been designed for a throughput capacity of 2.0 Mty of raw
coal per annum. The washery will produce three products viz. metallurgical/ washed
power coal for steel making after blending/ thermal power stations and rejects.
Based on the technology selected, the likely average quantity of rejects to be
produced from the washery has been estimated as 0.494 Mty. The rejects produced
from new Bhojudih washery will be dispatched to customer through railway by BCCL.
BCCL shall ensure that the above mentioned facilities shall be ready for use
as per the requirement for timely start of construction activities as well as operation
of the washery.
2.7.6
RESIDENTIAL AND WELFARE FACILITIES
The washery is proposed to be installed on Build, Operate & Maintain
(BOM) basis. It is expected that the residential & welfare facilities for the manpower
will be arranged by BOM operator.
It has been considered that the residential & welfare activities for manpower
required for BCCL will be shared with the project facilities of existing Bhojudih
washery.

2.8.1
ECONOMICS
CAPITAL ESTIMATE
The washery is to be set up under Build-Operate-Maintain (BOM) concept as per the
prevailing policy of CIL. The BOM operator will be selected by global bidding. The
BOM operator will build the Washery and operate & maintain the washery thereafter
for a period of 10 years.
Bhojudih NLW Washery (2.0 MTY) EIA_EMP
II-30
The capital required for transportation services for men as well as material
will be outsourced. Residential & welfare facilities for the manpower will be arranged
by BOM operator within the existing facilities available in the vicinity of the area.
Hence, no capital has been considered for the same. It has been envisaged that
existing railway siding of Bhojudih Washery will be extended up to the proposed new
Bhojudih Washery and fast loading system will also be prepared at the railway siding
separately by BCCL. Hence, cost has been provided on this account in the total cost
estimate. It has been considered that total capital will be funded from own resources
of BCCL. Hence, 100% equity capital has been considered.
The broad initial capital estimate has been done considering the operating
conditions, washing scheme envisaged and infrastructure facilities for taking
investment decision by BCCL and customization of Bid Document. While estimating
this capital, following tentative provisions have been considered:
-
Raw coal receiving by railway wagons from the linked mine.
-
Screen-cum-crusher house
-
Half-day storage of raw coal
-
Washery building
-
4000 tonnes covered storage of metallurgical coal
-
One-day production/ 6000 tonnes (whichever is more) covered storage of
middlings.
-
4000 tonnes covered storage of rejects.
-
Emergency slurry pond
-
Weighbridge in motion for raw coal, Metallurgical coal , Middlings and
rejects
-
Fast loading system for dispatch of metallurgical coal, middlings and
rejects through new railway siding.
-
Administrative buildings and other allied structures (viz. stores, workshop,
outdoor sub-station, water storage, first-aid Centre, canteen, security
check post etc.)
Bhojudih NLW Washery (2.0 MTY) EIA_EMP
II-31
-
Major technological equipment along with two years critical spares
-
Conveyor gantries, belt conveyors
-
Plant control system, instrumentation, quality & quantity monitoring system
-
Power and water supply arrangement
-
Roads, culverts, green belt, boundary wall, environmental control units,
firefighting equipment etc.
The total capital investment based on the above considerations works out to
about Rs.30414.44 lakhs. Out of this total capital, Rs.24255 lakhs is required for
scope of work of BOM Operator (ACB India limited).
The balance capital of
Rs.6162.44 lakhs(estimated) is for fulfilling BCCL’s obligations viz. fast loading
system, extension of existing railway siding, & its modification, approach road, power
supply arrangement, FR preparation cost etc.
2.8.2
COST OF PRODUCTION
The cost of production based on the broad capital investment, quality of raw coal and
the technology envisaged has been computed considering the following:
-
Notified selling price of raw coal including royalty & SED.
-
Crushing charge of ROM coal.
-
Cost of transportation of raw coal from linked mine through rail. The
average transportation cost per tonne of raw coal from the linked mines
has been considered as Rs.262.60 .
-
Operating cost of washery per tonne of raw coal input is Rs.315.80.
(BOMO part + BCCL Part + depreciation & interest). While estimating the
operating cost, it has been considered that security services, canteen
services etc. will be outsourced.
-
Reject disposal has been considered through railway
-
Projected yield of clean coal.
Cost of production per tonne of metallurgical coal has been worked out to
Bhojudih NLW Washery (2.0 MTY) EIA_EMP
II-32
Rs 3979.38 and the selling price of metallurgical coal as Rs.5708.82 per tonne at
desired ash of 18.0 %. The profit per annum has been computed as Rs.6813.98
lakhs (before tax).

4.1.3
Air Environment
With a view to collecting the samples for SPM, RPM, SO2 and NO X,
Envirotech make Respirable Dust Samplers (RDS) along with gaseous
attachment APM 411 were used. The instruments were well capable of
drawing air at a flow rate of 1 to 1.3 m3/min with very little pressure drop.
Glass micro-filter papers (GFA Sheets, Whatman) were used for the
collection of SPM. SO2 was collected by drawing air at a flow-rate of 0.5
liters per minute (lpm) through an absorbing solution i.e., Sodium
Tetrachloromercurate (West and Gaeke Method) and NO x were collected
by drawing air at a similar flow rate through the mixture of absorbing
solutions i.e. Sodium Hydroxide and Sodium Arsenite (Jacobs and
Hochheiser method). The measurement for both SO 2 and NOx was done
colorimetrically. All the analyses were carried out as per IS-5182.

Water Quality Assessment
Four water samples comprising two from surface one from ground water
and one from effluents water resources were collected in Jan to March
2015 to assess the water quality of the Cluster-IX and Cluster IX mining
area of BCCL which is near by the Bhojudih Washery. Samples were
preserved immediately after collection for the analysis of various water
quality parameters. The samples were preserved for trace metals analysis
by adding 2ml of 6N HNO3 to 100ml of sample.Testing of water samples
were done as per standard methods described in Standard Methods of
Analysis of Effluents Water Samples, Part A Schedule VI, 1993. Standard
method for the examination of water and wastewater, published jointly by
APHA, AWWS and WPCF and Manual on Water and Wastewater
analysis by NEERI were followed. pH, temperature, conductivity, total
dissolved solids and dissolved oxygen (DO) of the water samples were
measured in the field itself using Water Analyser Kit. Heavy metal analysis
were carried out by ICPMS by Central Institute of Mining and Fuel
Research.

4.3 Noise Environment
Sound is produced due to the vibration of bodies or air molecules and is
transmitted as a longitudinal wave motion. Sound wave is characterized by
the amplitude of pressure changes, their frequency, and the velocity of
propagation. It is therefore a form of mechanical energy. Intensity of sound at
a point in space is defined by the rate of flow per unit area, measured in watts
per m3. Intensity is proportional to the mean square of the sound pressure.
Sound intensity of practical interest covers a very large range and is therefore
measured on a logarithmic scale. The relative intensity level of one sound with
respect to another is defined as 10 times the logarithm (to the base of 10) of
the ratio of their intensities. Levels defined in this way are expressed in
decibels (dB). To establish an absolute level, a reference value must be
agreed upon. Thus the sound pressure level of a sound with a mean sound
pressure p2 is:
Lp = 10 Log 10 (P/Pref) 2 dB
Where the references pressure ''Pref.'' has an internationally agreed value of
20 micropascals. Because the effects of noise depend strongly upon
frequency of sound pressure oscillation, therefore, spectrum analysis is
important in noise measurement. The range of audible frequencies generally
lies between 20 and 20,000 Hz. It has been found that sounds between 1000
and 4000Hz are normally most easily heard. Loudness of sound is a function
of both intensity and frequency. In view of this, sound loudness is measured in
terms of sound pressure level (SPL) through a network of filters that represent
frequency
response
of
the
human
ear.
Such
frequency-weighted
measurements are referred to simply as sound level. ''A'' weighted sound
pressure level scale is the most accepted.
Measurement of sound level may be averaged over two distinctly different
periods of time. Steady sound levels and instantaneous levels of variable
sound are measured on very short-time scale of 1 sec. or less. Variable
Bhojudih NLW Coal Washery (2.0 MTPA) EIA/EMP
IV-13
sounds can be measured with a much longer time, over period of hours (say 8
hrs which is shift duration) and are expressed in terms of the equivalent
continuous pressure level (Leq).
Equivalent continuous sound pressure level (Leq) is that level of steady
sound, which over the same interval of time contains the same total energy as
the fluctuating sound. Thus, Leq is a scale for the measurement of long-term
noise exposure. There is large number of noise scales and rating methods
based on average or weighted averages derived from the detailed noise
characteristics. Equivalent sound level forms a useful measure of noise
exposure and forms basis of several noise indicators. It is defined asLeq = 10 Log (1/Tfot 10 Lp (t)/10 dt) dB(A)
Where Lp (t) is instantaneous sound pressure level and T is time of averaging
normally 8 or 24 hours.
4.3.1 Instrument Used and Methodology
Noise level study has been done for monitoring the ambient noise level in the
core and buffer zone. Mip-oy integrated sound level meter meeting IEC-197A
was used to measure the noise level. Average day and night Leq values have
been assessed at each location for four hours duration both during day and
night time with the interval of 30 minutes.
4.3.2 Noise Standards
Central Pollution Control Board has stipulated some specific standard for
ambient noise-level in industrial, commercial, residential and silence zones for
both day and night time. These are given in Table 4.12.

4.3.3 Assessment of Noise Level
To assess the ambient noise level, measurements have been carried out at 8
sites, which are listed in Table 4.14.
4.3.4 Results and Discussions
Noise,
often
defined
as
unwanted
sound,
interferes
with
speech
communication, causes annoyance, distracts from work, disturb sleep thus
deteriorating quality of human environment. Noise level was measured at
several locations in the human settlements around the proposed mining site
by using precision noise level meter.
Detailed analysis of noise has revealed that there is no noticeable impact of
Bhojudih NLW Coal Washery (2.0 MTPA) EIA/EMP

noise in the surrounding environment. All the study sites in the residential
areas exhibited a noise level well within the corresponding threshold limit
value as prescribed by CPCB, both during the day and night time. At
Pathardih and Bhowrah the noise level is relatively higher as compared to the
other sites. It is mainly due to the traffic (Road and Rail) and commercial
activity of the town area. The result along with monitored location is given in
Table 4.14.

Soil Environment
Soil is one of the three major natural resources, alongside air and water. It is
one of the marvelous products of nature and without which there would be no
life. Soil is made up of three main components – minerals that come from
rocks below or nearby, organic matter which is the remains of plants and
animals that use the soil, and the living organisms that reside in the soil. The
proportion of each of these is important in determining the type of soil that is
present. But other factors such as climate, vegetation, time, the surrounding
terrain, and even human activities (eg. Mining, farming, grazing, gardening
etc.), are also important in determining the type of soil.
4.4.1 Soil Quality
To assess the impact of mining on soil in and around cluster-X which is near
by Bhojudih Coal Washery, present soil quality of the area has been
evaluated with respect to physical and chemical parameters. The physicochemical properties of soil, which are important for plant growth and
agricultural productivity, are texture, bulk density, moisture content and water
holding capacity, pH, EC, Organic Carbon and Nutrients.

Analysis of soil samples reveals that there is no wide variation in the physical
and chemical properties of the soil. Particle size analysis shows that the
texture of the soil is of sandy clay loam and sandy loam in nature. The soils
are slightly acidic to neutral (pH 5.6 to 7.6). Electrical conductivity
measurement of the soil samples suggests that total soluble solid
concentration is in the normal to fairly good range. The values of EC ranged
from 0.6 to 1.2 mmhocm-1. The bulk density was found to vary from 0.99 to
1.24 g/cm3 showing compactness while moisture content ranged from 1.38 to
6.16 %. All the samples showed moderate to high water holding capacity
ranging from 22.46 to 59.74 %. The values of organic carbon of all studied
samples of agricultural soil were found to be in low to high range (0.18 to 0.78
%). The analysis of available Nitrogen, Phosphorus and Potassium states that
though the agricultural soils were in the mining area, they had good fertility
status. The Av-N and Av-K were in the medium range (68 to 180 Kg/ha) and
(48 to 165 Kg/ha), respectively. The OB dump sample was of lower fertility
with low Av-N and Av-K. The Av-P in all the samples including the OB dump
were found to be in the medium to high range (5.1 to 12.7 Kg/ha).

Flora and Fauna Survey
A preliminary survey of the study area has been performed to get a general
picture of the landscapes in vegetation. Traverses have been taken within
different zone of the study area to note major vegetation patterns and plant
Bhojudih NLW Coal Washery (2.0 MTPA) EIA/EMP
IV-20
communities including their growth form and dominant species. Square
shaped quadrates of 0.1 ha size were selected based on the representation of
plant species and number in it. Faunal survey was based on the data of
forest department, personal observation and interaction with natives.
Publications referred for completing this study were of Jharkhand State Forest
Department, A Revised Survey of the Forest Types of India; by H. G.
Champion & S. K. Seth, The Book of Indian Birds; by Salim Ali and The Book
on Indian Animals; by S. H. Prater, etc.
Topography of the area
The study including the core zone has been bifurcated by River Damoder
which enters in the study area from west and traverses towards the east. On
the left portion of river intense mining activities predominate while towards
right portion of the river relatively fever mining projects and rural settlement
predominates. The area is largely marked with undulating terrain, open cast
mine pits, OB dumps, and plains, complemented with plantation &
characteristic forest type. The forest of different stages is confined in the west
and south west part of buffer zone. South eastern, eastern, northern, northwest and some portion of western side of the study area is devoid of natural
forest and predominantly occupied with mining activities, settlements, fallow
land, open scrub and agricultural activities. The undulating topography and
presence of impervious hard rock, controls the soil depth and soil moisture
profile of the study area which has obvious variations from place to place,
hence the forest type.
4.5.1 Natural Vegetation in the area
Characteristic forest type of the area, distributed along the topography is
mainly Tropical Moist Deciduous Forest and Tropical Dry Deciduous Forest.
Forest types with their sub group in the study area were characterized as
follows:
Type/No.

Distribution of forest is fragmented and restricted to the patches between west
and west to south west portion of the study area. Within the forest boundary
there are large patches of open scrub with rural settlements. At several places
this forest boundary is fragmented due to roads. The total forest area of buffer
zone is a very small fraction of the total study area.
4.5.2 Flora and Fauna Distribution
Major landuse/land cover in the area is agriculture, waste land, mining
activities including pit and dumping area. There is devoid of systematic
irrigation facility and rain fed agriculture is being practised. Rice is the main
staple food of the district and it is chiefly grown. Vegetables are also cultivated
near water course in some parts of the area. Paddy, fruits and vegetables,
cattle rearing, poultry, piggery, etc. are the natural way of living. The mixed
flora consists of the following species: - Asan, Karam, Guri, Sidha, Mahua,
Gamhar, Bid, Semal, Piar, Bel, Dhatura, Salai, Kusum, Sisam, Palash etc
.The area is not very rich in floral and higher fauna.
Snakes and lizards are quite common. Varieties of birds are observed
specially in the winter season. The fragmented and poor vegetative cover,
long mining history and disturbed surrounding area does not support growth
of variety of faunal species. Prominent wild species include Bengal fox, black
napped hare; squirrel, jackals and porcupines. Amongst birds the bulbul, the
white-breasted kingfisher, magpie robin, spotted dove, mayna, pigeon,
parakeet etc. are prominent. Amongst reptiles, several poisonous like cobra,
viper, krait and non-poisonous snakes (like boa, rat snakes, green whip,
Bronze backed tree snake etc.) are abound in this area. The garden lizard
and monitor lizard are also seen. Variety of butterflies (like common grass

yellow/common jezebel) and insects (such as beetles, spiders, red ants, and
flies) are spotted in abundance in the study zone.

4.5.3 Flora community analysis
Forest cover in this cluster has been divided into three areas for community
analysis. Each area has been analyzed with ten quadrate analysis selected
randomly. Altogether the plant thirteen families with fifty seven species were
represented in the quadrate study in this cluster. The Cluster-X has been
divided into Area - I Brindabanpur, Area - II Loyabad and Area – III Barazore.
In the community analysis, frequency, dominance and density of top canopies
has been measured in absolute and relative terms.
4.5.4 Assessment Techniques
Traverses have been taken in all three Areas and it has been decided to
select the sampling sites randomly and measure with the quadrates of 10 X
10 m2 size.
Precaution has been taken while selecting the sites so that
representation of prevailing ecological parameters, anthropogenic and natural
stresses in the study samples may not get neglected. The properties of
vegetation with reference to species composition and functional attributes are
expressed on species basis.
Communities’ analysis parameters taken into account are number of
individuals, their distributor and frequencies of occurrence in each quadrate.
Bhojudih NLW Coal Washery (2.0 MTPA) EIA/EMP
IV-30
The density measurements reflect as to how many individuals were present,
the dominance measurements denote which species is largest in terms of its
presence and the frequency measurements indicate how widely species is
distributed among the same plots. Importance value is a reasonable measure
to assess the overall significance of a species since it takes into account
several properties of the species in the vegetation.
To calculate Importance Value Index, following parameters were
assessed from quadrate analysis:
Total number of individuals of one species
I.
Density =
Total number of quadrates studied
Total number of quadrants in which species occur
II.
Frequency =
Total number of quadrates studies
Total cover or basal area of Individual species
III.
Dominance =
Area sampled
Basal Area = πr2 = π (d/2)2
Where , d = Diameter at breast height (DBH) and r = radius
Density for a species
IV.
Relative Density =
x 100
Total density for all species
V.
Relative Frequency =
Frequency values of one species
x 100
Total frequency values of all species
Total basal area of species
VI.
Relative Dominance π =
x 100
Total basal area of all species
VII.
Important Value Index (IVI) = (Relative Frequency + Relative Density +
Relative Dominance)
The results of quantitative parameters are given .Important Value Index (IVI)
indicate that in the area I, II and III of Cluster-X, Azardirachta indica (74.73), is
dominant species which is which is a member of Meliaceae family. The next
dominant species was Dalbergia sissoo (31.45), a member of Fabaceae
family.

Socio- Economic Environment
A number of villages have been considered for socio-economic study of
Cluster-X which is nearby of the Bhojudih Coal Washery of BCCL. Basic data
pertaining to population, schedule caste (SC) and schedule tribe (ST),
education facilities, literacy, basic amenities and main workers, marginal
workers, non-workers by sex etc. have been collected for the Census Book,
2001, for all the villages. Field survey has also been carried out on different
aspects of socio-economic dimensions/ indicators to know the people’s
perception on the mining operations and to determine the quality of life of the
people living in the area. Various socio-economic dimensions have been
discussed in the following sections.
4.6.1 Demographic Pattern
Population of different villages falling in the core and buffer zone of the BCCL
Cluster-X .Population density of the core zone villages is lower than the
surrounding villages of buffer zone. The population of SC and ST in the core
zone villages is, constituting 40-45% and 10-15% respectively of the total
population. In some of villages the population of female is more than the male.
4.6.2 Literacy
The literacy rate is higher in buffer zone villages, however the overall literacy
percent is very poor and below the national average. Female literacy rate is
much lower than male. During socio-economic survey it has been found that
girl child is mainly undertaking the house hold activities. The socio-economic
condition & educational background of the families stand in the way to give
better education to the girls. The survey has also revealed an overall decline
in the percentage of persons educated beyond high school level and the trend
is more prominent in the case of females. Only primary and middle school is
present in the leasehold area while higher centers of learning are at a
distance of 10 to 20 km.
Bhojudih NLW Coal Washery (2.0 MTPA) EIA/EMP
IV-35
4.6.3 Basic Amenities
There is lack of basic amenities like hospitals, electricity, telephone etc. in
most of the buffer zone villages. All the houses are kuchha with mud walls
and only few villages having brick houses. There are only few primary school
and high schools in the core zone. One has to travel 10-20 km for graduation
and post-graduation study. The health facility and availability of doctors are
also poor in the core zone areas, however the medical facilities are provided
by BCCL under the CSR activity in the area. Amlabad, Digwadih and
Jamadoba area have some practitioner doctor available. Peoples have to
travel 15 to 25 km on an average to reach nearby health centre. Most of the
villages are connected by kuchha roads to district headquarter. There is lack
of higher educational facility in the area. Most of the households are using
firewood and coal as fuel. The worker distribution in the core and buffer zone
villages is summarized.
House to house survey has revealed that drinking water facility is a problem to
the local people. A significant number of families are depended on water tank,
local rivers, nallas and streams for drinking purpose.
Under medical facilities all the system such as allopathic, homeopathic and
ayurvedic medicines are available at a distance of 5-10 km distance. Only in
Amlabad, Digwadih and Putaki is having a registered practitioner. Overall the
quality of life is average to below average. This project will provide a muchneeded boost to improve the quality of life of the people residing in the area.
4.6.4 Workers distribution
Workers distribution is presented .Among the main workers male dominates in
all the villages while in the case of marginal workers females are found to be
prominent. It indicates that female have significant contribution in the
household economy. The socio-economic survey has been conducted to both
the zones and it has indicated that females are mainly engaged in householdbased activities. The women are also helping in business and small-scale
industry to improve the economic condition of the family. Mining is the
Bhojudih NLW Coal Washery (2.0 MTPA) EIA/EMP
IV-36
foremost economic activity. Socio-economic study reveals that most of the
families in this zone are getting benefits directly or indirectly from the mining
industry activity of the area.

ANTICIPATED ENVIRONMENTAL IMPACT ASSESSMENT &
MITIGATION MEASURES
5.0
GENERAL
The aim is to ensure that potential environmental problems are foreseen and avoided
at an early stage in the planning cycle so as to prevent measures to minimize
anticipated impact. The EIA mechanism shall be applied to the project in the following
order of priority:
 Avoid adverse environmental impact
 Minimize and control adverse environmental impact
 Mitigate adverse environmental impact
The major potential source of environmental contamination from coal washeries
includes: washery rejects (solid waste), thermal dryers (air pollution), liquid effluent
streams, coal storage and handling (fugitive dust and runoff), and coal transportation
(fugitive dust). The disposal of coal washery waste is a potential serious problem. Coal
washery rejects consists of waste coal, slate, carbonaceous and pyretic shales, and
clay associated with the coal seam. It varies considerably in physical and chemical
characteristics depending on both its source and the nature of the preparation process.
The main air pollutant from storage, transportation and handling of raw coal and
washed coal is fugitive dust. The amount of dust generated and its impact varies widely
and depends on meteorology, topography and characteristics of coal.
The water pollutants directly associated with the washing of coal are primarily dissolved
and suspended solids. The dissolved solids are mostly inorganic in nature and
compounds leached from the ash fraction during the washing process.
Another environmental consideration associated with coal storage is coal pile leachate
resulting in contaminating surface and groundwater. Coal pile leachate is generally
similar to acid mine drainage. The quantity of coal pile leachate is highly variable
depending upon the coal residence time, the topography and drainage area of the coal
pile site, the configuration and volume of the stockpile, precipitation and temperature.
5.1
LAND ENVIRONMENT
The proposed site has 15 Hectares land. Various installations required for the washery
will be suitably located within this land. Sufficient land is available along the siding and
is in possession of BCCL.

Siding 5.45 Ha)
Anticipated Impact
Land of the plant area is barren with few shrubs having low fertility. Hence this project
would have a no impact on agricultural production.
During the construction phase, the adverse impact is due to soil erosion and blanketing
of the top soil. Some readily erode due to pumping and digging activities. Temporary
hutments construction activities and poor sanitation facilities will diminish the actual
aesthetic value of the area.
In contrast, to the construction phase, during operation of the plant, the land-use
pattern will stabilize and no further drastic change is expected. Colony, schools,
hospitals, recreation centers etc. will be shared by the adjoining coal projects. If
needed, fertile soil will be brought from elsewhere over the existing soils for fresh
plantation. Land escaping will be undertaken to make the land-form compatible with the
surrounding.
Surface run off caused by precipitation may pass through stock-piles and reject dumps
causing erosion and degradation in quality, unless suitable measures are adopted.
While passing through the stock-piles and reject dumps, it may carry solid suspensions
and chemicals. Drainage for surface run-off shall be incorporated.
Mitigation Measures
Land is already in possession of BCCL and is barren. It is vicinity of an existing coal
washery of BCCL and the siding with merry-go arrangement is existing. The siding will
be utilized with some modifications, additions and alterations. Thus no land acquisition
is involved. Thus it will not have no adverse impact on the local communities/villages

WATER ENVIRONMENT
Anticipated impact
 Quantity and characteristics of industrial effluent and their impact on the environment
 Impact on ground and surface water due to leachate, run-off from stockpiles and
washery rejects
 Impact on water bodies due to siltation from coal washery dumps caused by coal fines
 Impact on surface water bodies due to the discharge of effluent during the heavy
rainfall and during periodic cleaning of the system, if any
 Impact on ground water and surface water availability due to the project usage
Mitigation Measures
The process of the proposed washery is based on closed water circuit system. All the
water fed into the system will be collected after use and re-circulated after treatment in
various units and no effluent will be allowed to escape into the natural drainage system.
Moreover, washery circuit envisages dewatering system like Centrifuges & High
Frequency Screens for efficient recovery of solids from the slurry. The filtrate water
from these equipment will be recycled back to the system to ensure closed water
system. The solid thus obtained will be mixed with the clean coal & middlings. The
underflow of HF Screens and slurry, in case of emergency, may be fed to slime ponds
for settling & natural drying and subsequent reclamation of the dried fines. The
overflow water of slime ponds will be pumped back for re-use in the process. Thus, the
operation of the washery will not cause any pollution to the local source of water.
Provision of surface run-off settling pond shall also be provided, overflow water of the
settling pond shall be utilised for plant operation, dust suppression and in case due to
some genuine problems like heavy rainfall, it become necessary to discharge the
effluent to land, the effluent shall conform to the standards at the final outlet of the coal
washery.
Rain water pipes/drain provided in the buildings will discharge into the surface storm
water drains of open type of masonry construction having adequate cross section and
slope for carrying only storm water to nearby natural streams.
 Provision of operation with zero effluent discharge has been made.
 The slime pond shall be constructed to prevent percolation into ground water, if
required. Settling pond over flow shall be recycled fully
Bhojudih NLW Washery (2.0 MTPA) EIA_EMP
V-3
 Garland drain(s) around the stockpiles and other process areas to collect and carry the
contaminated water to treatment/settling pond shall be provided.
 Properly designed system to collect and divert the storm water shall be provided
 Provision of catch drains and garland drains around the plant and storage yards to
cater the maximum run off from the catchments shall be provided
 In this proposed project consumption of water per ton of coal processed will be 0.12
cu.m per ton of coal. Standard automatic measurement practices shall be adopted.
 Settling pond for surface run-off with drainage system shall be provided.
 If, in case, due to some genuine problems like periodic cleaning of the system, heavy
rainfall etc., it become necessary to discharge the effluent to land, the effluent shall
conform to the standards at the final outlet of the coal washery: pH - 5.5-9.0, Total
suspended solids - 100 mg/l, Oil & Grease – 10 mg/l, B.O.D (3 days 27 oC) - 30 mg/l,
COD - 250 mg/l and Phenolics - 1.0 mg/l. The efficiency of the slime pond/ surface runoff settling pond shall achieve minimum 90 percent efficiency.
5.3
AIR ENVIRONMENT
Anticipated Impact
The source of air pollution from the coal washery includes from ROM coal
transportation, loading and unloading from trucks, handling, grinding, sizing, screening,
grinding and intermediate process operations, drying and storage etc.
The impacts on ambient air quality are highlighted in the following paragraphs:
(a) The ambient air quality is influenced due to the presence of SPM, PM 10, PM2.5, SO2 &
NOx, which are generated due to various activities like run-of-mine, transportation,
loading and unloading from wagons, handling, grinding, sizing, screening, grinding and
intermediate process operations, drying and storage etc. Further, the ambient air
quality may be affected marginally to a varying degree due to the mining activities of
other nearby opencast and underground coal mines of BCCL. The concentration of
pollutants may vary depending upon the various micro-meteorological parameters and
the seasons of a year.

AIR POLLUTION CONTROL MEASURES
The washing process is based on wet method of washing. In view of above, large-scale
emission of dust and pollution of ambient air due to dust is not foreseen. The washery
envisages receiving –200 mm raw coal and subsequent crushing the same to (-) 50 mm which
will be treated by wet process. Some dust may be generated and emitted into the atmosphere
during receipt, screening, crushing and conveying of coal. Generation of dust and its emission
into atmosphere is also apprehended due to large scale movement of vehicles involved in raw
coal transportation, dispatch of clean coal and disposal of rejects.
The necessary measures which have, therefore, been envisaged for prevention of dust
formation are described hereafter.
a)
Preventive Measures:
- Construction of permanent metalled road.
- Routine maintenance of Heavy Earth Moving Machinery (HEMM) to reduce
gaseous emissions.
- Provision of gas filter for exhaust fumes from HEMM.
- Limiting the speed of vehicles to reduce dust generation.
- Provision of air tight control rooms in washery, electric sub-stations, etc.
- Thick green belt (with tall trees) around proposed raw coal receiving
arrangement and around washery complex.
- Ventilation arrangement with proper ducting and fans are considered for a
cleaner environment.
b)
Suppressive Measures:
- Provision of water spraying arrangement at raw coal receiving arrangement.
- Use of dust suppression/ dust extraction system wherever essential in the plant.
- Regular spraying of water with water sprinklers on roads, plantation of trees
along the road sides and in open spaces.
- Frequent and at regular intervals, water will be sprayed on coal transport roads,
service roads. Mobile water sprinklers will be provided for dust suppression.
- Greenbelts in and around washery premises besides avenue plantation along
roads wherever possible.
The other measures taken shall be as enumerated below:
 The unmetalled roads shall be kept free of ruts, potholes, etc.
 Physical removal of dust from the roads.
 Limiting the amount of stock by giving close attention to marketing besides
following the "first-in and first-out" sequence.
Bhojudih NLW Washery (2.0 MTPA) EIA_EMP
V-6
 Attention to the following while stacking of washery products:
 Proper dimensions of stack (height to be limited to not more than 8m).
 Dozing/compaction to make the stock semi-consolidated.
 Regular and strict supervision of stacks.
 Provision of fire fighting arrangement with supply of adequate quantity of water
at sufficient pressure.
 Infusion of nitrogen along with new fire fighting chemicals like 'Soil-Cement',
through perforated pipes laid in the grooves made on the ground to delay
spontaneous heating by reducing/preventing ingress of oxygen or air into the
stack.
5.4 Noise Environment
Anticipated Impact
During the construction phase of the site, the source of noise pollution is expected
by Construction , installation and commissioning of the equipments.
(i)
(ii)
During operational phase, the following sources of noise pollution is expected:
Due to operation of the machinery and /or DG sets
Due to noise generated by large trucks for transportation of materials and by,
crushing, grinding, screening and conveying machinery etc. in the process.
Mitigation Measures
The following measures therefore, have been envisaged to reduce the noise level
to the minimum and to protect the workers from noise hazard.
- Use of equipment with arrangements for absorbing the operational noise.
- Use of insulated cabins for operators
- Use of rubber/ polymer liners in chutes and hoppers
- Use of ear muffs by workers in the zone of high noise source (if any)
- Plantation of trees around the plant area.
- Routine maintenance of HEMM.
- Regular maintenance with prompt replacement of worn-out parts/ liners etc.
- Environmental specifications for equipment purchase to meet the noise

ENVIRONMENTAL MANAGEMENT PLAN
10.1
INTRODUCTION
The activities associated with project construction and project management are
likely to have minimum adverse impact on various environmental attributes
including air, water, noise, soil, socio-economic profile and bio-environment. To
ensure that levels of pollutants do not exceed the limits prescribed by regulatory
authorities, following exercise has been taken up.
● Monthly data from nearby cluster –IX and X has been utilized for assessing the
base line condition of the project area.
● Likely impacts on environmental attributes due to project construction &
operation have been assessed using standard method.
With above exercise, the anticipated levels of pollutants in environment have been
assessed.
Environment pollution mitigation measures have been recommended to minimize
the impact & to limit them within prescribed level. These environmental mitigation
measures are able to be implemental throughout the life of the project.
In addition, environmental parameters will be monitored on regular basis to ensure
that level of pollution is within the prescribed level.
(The project proponent will submit several statutory reports relating to project’s
environment impact).
From the above, it may be seen that environmental management of the project
during the full life will involve planning, design & implementation of several
activities. This will require an exclusive budget and a dedicated organization.

SUMMARY AND CONCLUSION
11.1
INTRODUCTION
In the preceding chapters various environmental issues associated with the project
construction and operation, pollution mitigation measures and other related issues
have been covered. In this chapter, the summary of various issues are described.
11.2
PROJECT DESCRIPTION
The project relates to washing of raw coal, i.e. Run-of-Mine (ROM) coal mined from
nearby mines. Washing is required to improve the quality of raw coal so that washed
coal can be used for steel production as well for thermal power plants. The
arrangements in the proposed plant includes:●
●

Raw coal Receipt System
Raw coal crushing & screening system
Raw coal handling system
Coal washing circuit
Fine recovery circuit
Waste water treatment system
Product coal handling system
ANTICIPATED ENVIRONMENTAL IMPACT
The project activities will have impact on environmental attributes. Environmental
impacts on following environmental attributes have been assessed.
●
●
●
●
●
●
Ambient Air Quality
Ambient Noise Level
Surface Water Quality
Land
Bio-environment including Flora & Fauna
Socio-economic profile.
The impact study is limited to study area of the project site.
(A) Ambient Air Quality :
Following air quality parameters have been included in impact assessment.
-
Particulate Matter (PM10)
-
Particulate Matter (PM2.5)
-
Sulphur Di-oxide (SO2)
-
Oxides of Nitrogen (NOx)
Incremental value of each parameter due to project activities have been assessed.
Bhojudih NLW Washery (2.0 MTPA) EIA_EMP
XI-1
It has been found that estimated value of each parameter are below the value
prescribed by MoEF vide schedule VII of Env (Protection) Rules 86.
(B) Surface Water Quality:
At the operational stage of the project, effluents will be generated due to project
activities. These effluents are likely to have high suspended solid mostly of coal
particles, and inorganic solid particles. The level of trace elements would be low as
their levels in raw coal has been found to be very low. However, these effluents may
affect the quality of surface water if they are discharged without appropriate
treatment. The coal washery will maintain close circuit operation with zero effluent
discharge. Thus there will be no adverse impact on surface water quality.
Keeping the above in view, it is proposed to treat the effluent produced in washing
process and recycle them for reuse. Thus, there will be no discharge of effluent and
thereby there would be no adverse impact on surface water quality.
(B) Ground Water Quality :
Ground water quality can only be affected if there is seepage of polluted effluent
through storage. In this project, there is no proposal for storage of polluted effluents
in a tank through which there can be seepage; so there would be no pollution of
ground water.
(C) Noise Level :
Noise generating sources in the plant have been identified to be crushers, screeners,
conveyors & transfer points. They are mostly to be enclosed in the plants buildings.
Hence their impact on ambient environment will be minimal.
(C) Impact on Flora & Fauna :
The plant area is a waste land. The plant area does not have any forest cover or
plantation cover. Thus construction and operation of plant will not have any impact on
flora and fauna.
(F) Impact on Socio-economic Profile:
The land required for location of plant and development of project infrastructure is
owned by the proponent. Thus, there is no need for acquisition of Pvt. land for the
project. On the contrary, the project construction and operation will have positive
impact on account of following:
●
Creation of employment opportunities
●
Creation of income generation opportunities in terms of small contractual works,
opportunities in service sector, improvement in physical & social infrastructure
on account of CSR activities, etc.
11.4
ENVIRONMENTAL POLLUTION MITIGATION MEASURES
Activities associated with construction and operation of the plant will have negative
impact on environmental attributes. In order to minimize the negative impacts,
pollution mitigation measures have been recommended. They are briefly mentioned
below.

11.4.4
Installation of water sprinkling system at the ground coal stock for raw coal.
Raw coal crushers completely enclosed.
In Coal Handling Plant, water sprinkling system on all transfer points.
Belt conveyors handling coal enclosed from side and top.
Regular water sprinkling on paved area.
Green Belt along periphery of the plant area.
Tippers carrying raw coal and product coal to be covered.
Green belt along both sides of road.
Noise generating stationary sources, i.e. crusher, coal handling plant, etc. to
be enclosed.
Coal washing equipments are to be housed inside the building. Thus noise
generated by these equipments will not spread.
Vibrating equipments to be provided with vibration control pads to reduce
vibration and noise.
Green belt around plant area will help in mitigating noise.
BIO-ENVIRONMENT MITIGATION MEASURES
The site which has been selected for locating plant is free from forest / vegetation
cover. Thus construction of plant will not affect flora & fauna.
11.4.5
MITIGATION MEASURES FOR SOCIO-ECONOMIC PROFILE
The land which has been selected for location of plant and infrastructure is owned by
project proponent. It is free from human habitation. Land is a waste land. Thus
construction and operation of plant will not create any R&R issue. However, the
project proponent will undertake certain socio-economic development schemes under
CSR programme. The fund for CSR will be allocated on 2% of the average net profit
of the Company for the three immediate preceding financial years or Rs 2.00 per
tonne of Coal production of previous year whichever is higher.
Bhojudih NLW Washery (2.0 MTPA) EIA_EMP
XI-3
Peak Capacity of the washery is 2.0 MT. An amount of Rs. 40.0 Lakhs will be used
for the CSR works per year for washery.
11.4.6
OVERALL JUSTIFICATION FOR IMPLEMENTATION OF PROJECT
The project relates to washing of raw coal to improve its quality so that it can be used
for steel production. Steel industry is core industry. This sector is critical for overall
industrial and economic development of the country. Coking coal is an important raw
material for iron & steel production and its reserves in India is limited. In view of this,
it is necessary that the indigenous resource of coking coal is exploited and used to
support the iron & steel industry.

b. Brief description of the process with flow diagram
: Enclosed
c. Alternate technologies considered:
The proposed washery will meet the demand of clean medium coking coal by Steel Plants
to some extent and also power grade coal by Power sector.
Considering the low yield of clean coal, an attempt has been made to design an optimum
flow-sheet to be able to extract clean coal & middling to achieve the best technoeconomics. As per the selected flow-sheet, the RoM coal will be crushed to achieve
optimum liberation and will be further treated by gravity separation technique.
d. Reasons for selecting the proposed technology on environmental Considerations:
 The selection of coal washing technology has been derived from the raw coal
washability test data to achieve maximum revenue with proper conservation of
safety environment, minimum land use, proper care for the nearby surrounding.
 The washability test data indicates requirement of three stages washing to
achieve metallurgical as well as power grade coal suiting to the MoEF
Guidelines.
 The main Technology of washing of this project is a three stage washing with
Heavy Media Cyclone as main washing equipment.
 The technology envisaged is a zero effluent discharge from coal washing to the
nearby surrounding. Adequate dust suppression system has also been
envisaged.

We welcome the upcoming Project. Please
do proper implementation of pollution
control measures in the new project as
proposed because the existing Bhojudih
Coal Washery is causing very much
Environmental Pollution in the area. The
agricultural activities in the area also get
affected by the water pollution caused due
to existing washery. I also request West
Bengal Pollution Control Board to monitor
and take proper action in this regard. Local
people should be given priority for skilled
and
unskilled
employment
and
infrastructure facilities like road, School
and health centre should be made for local
people.
We welcome the upcoming Project with a
request to the management that it should
initiate the developmental work for local
like construction of schools and roads and
we also request to increase the fund for
Corporate Social Responsibility (CSR)
proposals so that the area as a whole can
be benefited from the same. We also
request that there should be provision of
manual loading /unloading of raw
coal/rejects in the new project so that there
will be generation of employment to the
local.
Much dust is generated from the existing
Bhojudih Coal Washery so we request that
BCCL management should take proper
pollution control measure like water
sprinkling etc. We want to mention here
also that dust is also generated due to
storage/transportation of ash from nearby
Santaldih Thermal Power plant. We
request the BCCL management to take
proper
attention
and
action
for
infrastructure development of locality such
as road network, school, and healthcare.

control measures will be
implemented properly in

proposed. Preference is
already given to eligible
local people in skilled and
unskilled employment
and
action
regarding
infrastructure facilities like
road, School and health
centre will be taken under
the CSR policy and as per

Regarding dust generation
from the existing Bhojudih
Coal Washery it will be
dealt with the discussion
