CHAPTER -1
INTRODUCTION
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. Madhuban NLW Wahery (5Mty) 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
The proposed Madhuband NLW coal washery will be located in the close vicinity of a existing coal washery in Jharia Coalfields under command area of Bharat Coking coal Limited. It is located in a non forest and non coal bearing area. It is planned for three prduct namely clean metallurgical coal, Power coal and rejects. Its normative and peak capacities are 5.0 MTPA & 6.5 MTPA respectively. The proposed project will receive coal from Muraidih OCP, Shatabdi OCP, Block-II OCP and Akashkinaree OCP with Muraidih OCP and Block-II OCP contributing 78% of raw coal. Clean coal from the washery will be linked to steel plants at Durgapur, Bhilai & Bokaro. The power coal (middlings) will be linked to the different power station, and the rejects to the

the washery situated under existing Madhuband Coal Washery has already been acquired under CBA Act. Unit Operation
Coal Cleaning Methods
The various procedures are broadly classified as the ‘Wet’ ‘and Dry’ processes. The dry process doesn’t involve the use of water, where as in the wet process, the water is the main medium for washing and jigging. Crushing
Purpose of the crushing is to reduce the Run of Mine (ROM) coal to a size suitable for washing and, size reduction involving various principles such as compression, impact, shearing, splitting and attrition
1. Primary crusher(s) are generally designed to receive ROM coal and reduce it to a top size of 2” to 8’’
Secondary crushers are generally designed to reduce the size (to a top size of 1 ¾”) of the middling fraction from jigs or the middling fraction from heavy – medium trough separators, and, in turn these fractions would be rewashed. Screening
Sizing is the separation of a heterogeneous mixture of particle sizes into groups wherein all particles range between a maximum and minimum size. Screens Used in Coal Preparation:
1. Scalping screen – for separating refuse and fines prior to size reduction
2. Raw coal sizing screen- for separating the raw coal into coarse and fine
size for further processing.
3. Pre-wet screen- to remove fines prior to the mechanical cleaning
4. Heavy media recovery screens- for recovery and reuse of magnetite
5. Desliming screens-to remove extreme fines; and
6. Dewatering screens-to remove water
Jigs
The methods operate by differences in specific gravity. Jigs rely on stratification in a bed of coal when the carrying water is pulsed. The shale tends to sink, and the cleaner coal rises. The basic jig is suitable for larger feed sizes. Although the Baum jig can clean a wide range of coal sizes, it is most effective at 10-35 mm. A modification of the Baum jig is the Batac jig, which is used for cleaning fine coals. The coal is stratified by bubbling air directly through the coal-water-refuse mixture in this cleaning unit. For intermediate sizes the same principles are applied, although the pulsing may be from the side or from under the bed. In addition, a bed or hard dense mineral is used to enhance the stratification and prevent remixing. The

mineral is usually feldspar, consisting of lumps of silicates of about 60mm size. Figure 2.1 shows a Baum Jig and a feldspar Jig for finer coal. Jigs offer cost effective technology with a clean coal yield of 75-85% at about 34% ash content. The jigs are used more frequently than dense-medium vessels because of their larger capacities and cheaper costs.
Figure 2.1: Baum Jig and Fledspar Jig
Dense Media Seperator
Dense-medium vessels also operate by specific gravity difference; however rather than using water as the separation medium, a suspension of magnetite and water is used. This suspension has a specific gravity between that of coal and the refuse and a better separation can be obtained. The slurry of fine magnetite in water can achieve relative densities up to about 1.8. Different types of vessels are used for dense-medium separators such as baths, cyclones and cylindrical centrifugal separators. For larger particle sizes, various kinds of baths are used, but these require a substantial quantity of dense- medium, and therefore of magnetite. For smaller sizes, cyclones are used where the residence time is short and throughput relatively high. Cylindrical centrifugal separators are used for coarse and intermediate coal. Dense-medium cyclones clean coal by accelerating the dense-medium, coal and refuse by centrifugal force. The coal exits the cyclones from the top and the refuse from the bottom. Better separation of smaller-sized coals can be achieved by this method. Key factors in the operation of any dense-medium system based on magnetite are the control equipment and the efficiency of magnetic recovery for recycle. There can be a build-up of other minerals in the medium, making control more difficult. Figure 2.2 shows example of a densemedium bath and a dense-medium cyclone.

Figure 2.2: Dense Media Seperator
Concentration Tables
Concentration tables are titled and ribbed and they move back and forth in a horizontal direction. The lighter coal particles to the bottom of the table, while the heavier refuse particles are collected in the ribs and are carried to the end of the table (Figure 2.3). Fine coal can be cleaned inexpensively with this unit, however, the capacity is quite small and they are only effective on particles with specific gravities greater than 1.5
Figure 2.3: Concentration Table
Froth Flotation Table
Froth flotation is the most widely used method for cleaning fines. Froth flotation cells utilize the difference in surface characteristics of coal and refuse to clean ultra fine coal. The coal-water mixture is conditioned with chemical reagents so that air bubbles will adhere only to the coal and float it to the top, while the refuse particles sink. Air is bubble dup through the slurry in the cell and clean coal is collected in the froth that forms the top. Figure 2.4 shows an example of froth flotation. This type of cleaning is very complex and expensive and is principally for metallurgical coals. One of the commonest steps to improve the performance of a flotation unit is to separate the pyrite at an earlier stage using cyclones, spirals or tables.

2.1.7 Technology & Process Description
RAW COAL RECEIVING, CRUSHING & SCREENING AND STOCK-PILING SECTION:
Raw Coal of (-) 200 mm size will be received over a Fixed Grizzly
(200mmX200mm) on the Ground Dump Hoppers (5nos, capacity 100 t each)
from the BCCL’s Rear Dumpers of 22 Tonnes capacity. There will be
weighbridges for weighing BCCL’s trucks-both loaded and tare weights.
Coal from the hoppers will be withdrawn by the vibrating feeders through Rod
Gate, located in the underground tunnel for feeding to the Conveyor (BC1,
capacity 1200tph).
This conveyor will carry the coal to a Sizer/Roll Crusher (1 no., capacity
1200tph OR 2nos 600 tph each), located in the crusher house where all coal
will be crushed to (-) 75mm.
The underflow product of the Sizer/Roll crusher shall be collected on a
conveyor (BC2, capacity 1200 tph ) which will carry the crushed coal to Tube
Stacker for ground storage of crushed coal (8000 t).
Crushed Coal will be reclaimed through Ground hoppers and Vibrating
feeders in turn feeding to Conveyor (BC3, 1200 tph) which will carry the Coal
to the Washery Building. Dozer or Pay loader will be used for pushing coal
into ground hopper as and when it will be required.

characteristics.
Coarse Coal Classification & Desliming: Crushed coal of (-)75 mm size at the rate of 1000 tph will be received through Raw coal belt conveyor (BC3) and discharged into the Raw Coal wetting launder where adequate water will be added for wetting of coal.
2.1.7.3 Deshaling Section:
Coarse coal Deshaling in HM Cyclone: Coal with water from the Wetting box will be fed into a raw coal sizing screen
(3001) where it is graded into (+) 13 mm as oversize and (-) 13 mm as
undersize. The oversize from the Raw Coal screen is delivered to the coarse
coal blending tank where it is pulped with heavy media supplied by the
Correct Media Pump from the coarse correct heavy media Sump, having the
required density. From blending tank coal with Magnetite media will be
pumped to the Coarse Coal HM Cyclone (3002). The Coarse Coal HM
cyclone will have two products: Overflow (deshaled coal) and Underflow
(reject). The H M cyclone overflow will be delivered to a Clean Coarse Coal
drain and rinse (D&R) screen (3003) for recovering the magnetite. The
Underflow of Coarse Coal H M Cyclone (sink) material will be delivered to a
Reject drain and rinse (D&R) screen (3004) for recovering the magnetite and
dewatered reject will be fed to Reject conveyor (BC4, capacity 500 tph) for
discharging into Reject Bin (capacity 550 t). The Heavy media as recovered
from both the above Draining & Rinsing Screens will be fed back finally to the
Coarse Coal Blending tank. (-)13mm from the raw coal sizing screen (3001) is
delivered to the Primary washing H M cyclone section
2.1.7.4 Magnetite Regeneration & Preparation:
The rinse water will wash away the adhering Magnetite media from both the
products of coarse coal cyclone and will be collected in the discharge side of
the D&R Screens underflow catch pan which will gravitate to a Dilute Medium
Sump. This dilute Media will be pumped to a Wet Drum Magnetic Separator
(3008) for recovery of the magnetite and recovered magnetite will
subsequently be fed to the coarse Correct Medium Sump. Effluent water

Water requirement and water Balance.
The proposed Washery will operate on the State of the art technology with 5 stage beneficiation process. The washery will operate under closed water circuit recirculation system with Zero discharge. The makeup water requirement for the washing process will be 904 KLD and shall be obtained from the nearby existing Jamunia Reservoir, which is managed by BCCL. However, the total water requirement for the washery Plant will be 1350 KLD. The additional water is for water sprinkling to arrest dust on the roads and for watering of planatation/ green belt and other miscellaneous use. The detailed water Balance for coal beneficiation is given in the diagram below. In addition, to this, there is a proposed scheme for Multipurpose utilization of surplus mine water by BCCL to pump out and collect water from neighbouring underground mines into a reservoir near Govindpur in the non-coal bearing area. By the time the washery construction is completed, the water available from this reservoir can also be utilized for makeup water required for the proposed washery.

2.3 DISPOSAL OF WASHERY REJECTS:
The washery rejects produced annually will be used in the proposed CFBC plant envisaged by BCCL. 2x75 MW capacity Thermal Power Plant based on CFBC (Ciculating Fluidised Bed Combustion) technology has been planned to set-up at Dugda 8 km away with specific investment of around Rs. 5.56 crores per MW. The brief proposal of the upcoming of the FBC TPP for utilization of washery rejects is given below:
The washery rejects and inferior grade coal having low calorific value are not
suitable for use in existing thermal power stations based on PF boilers, but
from the ENERGY CONSERVATION point of view, it is desirable that energy
content of these washery rejects / inferior grade coal is gainfully utilised. It
may be used for power generation based on fluidised bed combustion (FBC)
technology. In view of national electricity policy and MOEF directives for
gainful utilization of washery rejects having useful heat value, CIL intends to
set up FBC based thermal power plants of suitable capacity using washery
rejects as fuel with linkage from the 20 numbers of proposed washeries.
Proposed Madhuband NLW Washery EIA_EMP TEXT(FINAL) JOB No.
200310002
23
Setting up of FBC based power plants will not only utilize rejects from
washeries but also make power available at the door-step of coal fields with
reduction in harmful emissions from the combustion process. The whole
process is an environmentall friendly venture.
SITE SELECTION
A team of CMPDI engineers visited BCCLIin the 1st week of January,2011 for
discussions, site visit and collection of input data required for preparation of
Conceptual Report on setting up of FBC based power plant using Madhuband
washery rejects as fuel. Discussions with BCCL authorities revealed that the
land required for setting up of the FBC based TPP using Madhuband
Washery rejects (as indicated by CMPDI) was not available at or near
Madhuband. Hence, BCCL confirmed availability of sufficient land owned by
BCCL near Dugda Washery for setting up of a power plant with reject linkage
from both the proposed 5MTY NLW Madhuband Washery and the proposed
2.5 MTY Dugda Washery. BCCL has indicated an area of around 75
hectares, adjacent to the proposed Dugda Washery site and at a distance of
around 8 km from the proposed Madhuband Washery. The Conceptual
Report is already under preparation. Hence, the basic requirements for
setting up of the above power plant at the proposed site with reject linkage
from both the above mentioned washeries have been briefly enunciated in
this section.
REJECT AVAILABILITY AND POWER GENERATING POTENTIAL
The proposed 5MTY Madhuband Washery and 2.5 MTY Dugda Washery of
BCCL are envisaged to produce around 2 MTY and 0.5 MTY of washery rejects,
with an indicative power generating potential of around 165 MW. This power
potential is based on calculations, considering plant heat rate of 2500kCal/kWh
and a plant load factor (PLF) of 80%. The power potential calculations are based
on data regarding yield, moisture content and ash content of rejects, as obtained
from the Washery Division (based on HEC's guaranteed data) of CMPDI (HQ),
Ranchi. This is more than sufficient to sustain a power plant of 150 MW power
Proposed Madhuband NLW Washery EIA_EMP TEXT(FINAL) JOB No.
200310002
24
generating capacity. Hence, for suitability of unit size and in view of space or land
availability, unit size of 75 MW CFBC (Circulating Fluidised Bed Combustion)
boiler willbe selected for the proposed power plant of 2x75MW capacity. The
basic requirements have been worked out accordingly.
REQUIREMENT OF BASIC INPUT AND AVAILABILITY
The basic requirements for reject based power plant are:
- Availability of sufficient land for power plant, colony & ash dump
- Availability of adequate quantity of water throughout the year over the entire
life of plant
- Availability of adequate quantity of washery rejects
- Adequate arrangement for evacuation of generated power and nearness to
load center.
- Good accessibility by road or rail
- Ecology and Pollution aspects
REQUIREMENT OF LAND AND AVAILABILITY
The land requirement for a plant layout of 2x75 MW power plant at Siarmal is
estimated as under:
Facility Land requirement (hectares)
2x75 MW
Plant site 60
Colony, roads and other purpose 10
Sub-total of above 70
Ash Dump Area 20
Total Land requirement 90
Site for Madhuband FBC based thermal power plant
In the location plan of the area, BCCL has indicated an area of around 75
hectares for the proposed/probable location of the power plant site. It is adjacent
to the proposed Dugda Washery site and at a distance of around 8 km from the
proposed Madhuband Washery. There is more land available in the area for
future expansion, if required. It is also adjacent to the existing Dugda washery
site and well located with close proximity to nearby Damodar river, road, railway
line, both Madhuband and Dugda washery sites and connected by road. The
Proposed Madhuband NLW Washery EIA_EMP TEXT(FINAL) JOB No.
200310002
25
allocated land for the proposed site is enough for the plant site of 2x75 MW
capacity including green belt, water reservoir and reject handling facilities apart
from the power plant installations required for generation and the switchyard for
power evacuation. If there are sparable quarters in the nearby colonies of
adjoining coal mining projects of BCCL, then the housing facilities may suffice
instead of constructing new power plant colony. Dry ash disposal and disposal of
fly ash to cement plants, brick manufacturers in the vicinity, backfilling of ash into
mine voids of abandoned/ de-coaled mines is being explored. This shall be done
after conducting leaching studies through a scientific institute.
REQUIREMENT AND AVAILABILITY OF WATER
The Damodar river has been indicated as the source of the requisite quantity of
water required for the power plant. The proposed site is well located with close
proximity of around 2 km from the Damodar river. The river source is perennial
and can easily meet the water requirement of approximately 15 cusecs, 1500
cum/hr for wet ash disposal and 1000 cum/hr for dry ash disposal. This includes
make-up water for the circulating water system required for turbine condenser
cooling system, auxiliary cooling system, D.M. treatment plant, plant services,
ash handling and evaporation and drift losses in cooling towers. The required
water for the power plant can be easily pumped and carried through pipeline to
the main reservoir at the plant site. Option shall also be explored for utilizing
water discharge from the neighbouring underground mines.
REQUIREMENT & AVAILABILITY OF WASHERY REJECTS
Considering plant heat rate of 2500 kcal/kWh for 75 MW set (unit size), GCV of
rejects at 1500 kcal/kg and specific generation of 7008 kWh/kW/Year (PLF-
80%), annual requirement of rejects for installed capacity of 2x75 MW works
out to 1.84 MTY. An allowance of 5% has been considered for steam venting.
As mentioned earlier, availability of rejects from the proposed Madhuband and
Dugda washeries at BCCL is around 2.38 MTY which is more than sufficient
to sustain a power plant of 150 (2x75) MW power generating capacity. In case
of future availability of increased quantity of washery rejects, there is scope for
further expansion. The washery rejects of Madhuband Washery may be
Proposed Madhuband NLW Washery EIA_EMP TEXT(FINAL) JOB No.

transported by road for a distance of around 8 km and the washery rejects of
Dugda Washery may be transported by conveyors or covered trucks/
conyainer carriers directly from the washery premises .

ii) Power Evacuation from CPP
The power demand of the area can be easily met by the generated power and the
excess power produced can be pumped into the grid. Generated power at 11 kV
can be stepped up to 33kV/132kV as per requirement, either for BCCL power
consumption or for onward transmission to the grid, respectively, through the
Chandrapura sub-station of DVC, the nearest grid sub-station, at a distance of
around 2 km from the proposed site.
Power generated at 11 kV from the 2x75 MW turbine-generator units will be
stepped-up to 33 kV in the first stage and fed into the 33kV station bus. The
power required for own BCCL consumption, works out to around 50MVA for the
existing load of Madhuband and Dugda (mines and washeries) and another 50
MVA for the additional power demand of the proposed 132/33 kV substation,
located between Block IV and Block V areas of BCCL. This power can be drawn

coalfields as well. After providing for around 100MVA of power demand for own
consumption of BCCL, the remaining 50 MVA of surplus power can be fed into
the grid for power trading at agreed rates.
Running of CPP in synchronization with grid is technically feasible. It will require
strengthening of protection and metering system at both the ends. This will be
further facilitated by The Electricity Act 2003, that provides for National Electricity
Policy, Rural Electrification, open access in transmission, phased open access in
distribution, mandatory SERCs, license free generation and distribution, power
trading, mandatory metering and stringent penalties for theft of electricity. The
aim is to push the power sector onto a trajectory of sound commercial growth and
to enable the States and the Centre to move in harmony and coordination. Under
this open access regime legislated by Electricity Act 2003, the PLF of the above
mentioned FBC power plants can go upto 95% by running the power plant
parallel to the power grid and providing access for wheeling of excess power
generated into the grid for use by other consumers.
ASH DISPOSAL
60% to 65% of ash will be generated from the FBF TPP. Dry ash disposal and
disposal of fly ash to cement plants, brick manufacturers in the vicinity, backfilling
of ash into mine voids of abandoned/ de-coaled mines is being explored.
Regarding disposal to potential buyers like cement plants, brick manufacturers,
MOUs shall be entered prior to the commencement of the FBC TPP As per the
available literature Jharia Coalfield coal does not contain heavy metal or other
unacceptable leachates, therefore dumping of the ash from the CFBC TPP in
abandoned voids will not pose adverse impact on the hydrogeological regime.
However this will be done after conducting necessary leaching studies through a
scientific institute. An area of around 20 hectares has been kept for ash dumping
in dry/semi-dry form for quenching/handling before disposal. Mine voids for
dumping of the ash are available at Damoda Area, around 8 kms. away from the
proposed site. Possibility of ash disposal by quarry backfilling will be explored.
CAPITAL INVESTMENT

Total capital investment for 2x75 MW CFBC based power plant is estimated
approximately. At the time of preparation of Conceptual/Feasibility Report, the
exact cost estimation may be done. The specific investment for capital cost
works out to around Rs. 5.56 crores per MW.
CONCLUSION
As advised by the EAC/MoEF in the approved TOR the rejects generated from
the proposed washery will be fed to a CFBC TPP. The Project Report for the
integrated CFBC TPP is under preparation by CMPDI and will be completed
within a couple of months. It also has the approval of the competent authority of
BCCL. The CFB TPP shall also be ready for operation by the time the proposed
Madhuband washery comes into operation.

CHAPTER - 3
DESCRIPTION OF ENVIRONMENT
3.1 Introduction
The present environmental scenario has been described in this chapter in respect of ambient air quality, water quality, noise level measurement, soil quality, socio-economic scenario, flora & fauna, hydrogeology and land use/cover pattern.
Study Area – For the proposed project, the project area has been taken as the core zone and the area within a radius of 10 km of the core zone has been taken as the buffer zone
Period of Study – One season data in respect of Air quality, water quality, soil quality and noise monitoring has been done from April ’10 to June ‘10 and socio-economic & flora – fauna study has been done in June’10
Methodology of sampling 1. Ambient Air Quality Monitoring: With a view to collecting the samples for SPM, RPM, SO2 and NOX,
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 NOx 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 SO2 and NOx was done colorimetrically. All the analyses were carried out as per IS-5182.

2. Noise Level Monitoring:
Sound Pressure levels (SPL) have been measured by a sound level meter (Model: Lutron SL – 400). Since loudness of sound is important for its effects on people, the dependence of loudness upon frequency must be taken into account in environmental noise assessment. This has been achieved by the use of A – weighting filters in the noise measuring instrument which gives a direct reading of approximate loudness.
3. Soil Sampling:
The soil samples were collected by ramming a core – cutter into the soil upto a depth of 90 cm. The samples were then homogenized and packed in a Polythene plastic bags and sealed. The sealed samples were sent to the laboratory for analysis.
4. Water sampling:
The samples were analyzed for relevant physical, chemical and bacteriological parameters for drawing up the baseline data.
All the basic precautions and care were taken during the sampling to avoid contamination. Analysis of the samples was carried out as per established standard method and procedures prescribed by the relevant IS codes and standard methods (AAPHA).
5. Meteorological Observations:
During air quality monitoring period, meteorological station was established on the roof top of the Nehru Nagar. The selected station was free from obstructions for free flow of air from all the direction.

Details of the wind speed, frequency distribution and wind direction is given in Table No.3.20 and accordingly wind rose diagram has been developed for the month of summer season (April, May and June 2010) which is presented in the Figure 1.1. During Month of April, May and June, the predominant wind directions in study area were from West-South-west, West and South-West for 9.7, 8.75 & 7.85 percent of time respectively. The predominant wind speed was 5-8 km/h and 3-5 km/h for 29.94 and 21.19 percent of the total time respectively.
6 Socio-Economic Study
The descriptions and projections of social and economic conditions were carried out for Madhuband area the core zone (Madhuban Washery) and buffer zone. The study was concentrated in the buffer zone area, as there is no village in the core zone. Socio-Economic Scernario
Socio-economic profile of the study area is based on the data available from 2001 Census Report. The Socio-economic profile of the buffer zone of the project is based on Demmographic Survey done by CME, ISM, Dhanbad, during the month of June, ‘2010. In addition a systematic Socio-economic survey was carried out to develop Socio-economic scenario related to demography, health and food, access to education facility, occupational and income pattern, educational status, etc. this has been done on the basis of secondary data as well as a sample survey of the population of the area. The census data was obtained from the Census Office, New Delhi. The data revealed that the total population of the Madhuban area according to 2001 census is 106282 (Table.3.31). Out of total populaton 106282 the male populatin is 56499 and female population is 49783. the total numbers of households are 20987. The Socio-economic status of any area is influenced by various factors and therefore it was necessary to identify the main factors influencing the Socio-economic profile of the population in the region. In order to initiate the process, the team members started interacting with some local people at Madhuband with the help of the revenue officials as per the arrangement with the Tehasildar. The details of village wise demographic / social profile of the buffer zone are summarized below in Table No. 3.31. The sampled villages and size of the samples are given hereunder: Socio-economic in Table No. 3.2

Observations
The following observations are made from the analytical results of monitoring:
The average SPM concentration levels at different locations of industrial area (e.g., CISF camp, GM building, were within the range of 381 to 515 μg/m3. These were within the permissible level of statutory norm. Similarly, the average SPM concentration levels at different locations of residential, rural and other areas were within the range of 263 to 450 μg/m3 and were crossing the permissible level of 200 μg/m3 for residential, rural and other areas. At ISM (control site) concentration varies from 112 to 149 μg/m3 the average concentration was 132 μg/m3 which is below the standard limit.
The average RPM concentration levels at different locations of industrial area (e.g., CISF camp, GM building) were within the range of 175to 242 μg/m3 and were within the permissible level of statutory norm. Similarly, the average RPM (PM10) concentration levels at different locations of residential, rural and other areas (were within the range of 140 to 199 μg/m3 and were crossing the permissible level of 100 μg/m3 for residential, rural and other areas. Both the SPM and RPM concentration levels reduced significantly during the days having maximum rain fall. At ISM (control site) concentration varies from 54 to 80 μg/m3 the average concentration was 69 μg/m3 which is below the standard limit.
The average SO2 concentration levels at different locations of industrial area (e.g., CISF camp, GM building) were within the range of 32 to 33 μg/m3. These were within the permissible level of statutory norm. Similarly, the average SO2 concentration levels at different locations of residential, rural and other areas were within the range of 24 to 30 μg/m3 and were within the permissible level of 80 μg/m3 for residential, rural and other areas. At ISM (control site) concentration varies from 11 to 29 μg/m3 the average concentration was 22μg/m3 which is below the standard limit.
The average Nox concentration levels at different locations of industrial area (e.g., CISF camp, GM building) were within the range of 32 to 58 μg/m3. These were within the permissible level of statutory norm. Similarly, the average NOx concentration levels at different locations of residential, rural and other areas were within the range of 35 to 51 μg/m3 and were within the permissible level of 80 μg/m3 for residential, rural and other areas. At ISM (control site) concentration varies from 20 to 38 μg/m3 the average concentration was 30μg/m3 which is below the standard limit. Conclusion
The following conclusions can be drawn from the study of results of ambient air quality monitoring:
The concentration level for SPM, RPM, SO2 and NOX recorded at stations representing industrial and residential areas are within the prescribed limits as per GSR 742 (E) Dated 25.09.2000 of MOEF and NAAQS respectively. The

standard methods and procedures prescribed by the relevant IS Codes and Standard Methods (AAPHA).
3.3.5 Standards followed: Standard for mine water : GSR-742(E):2000 Standard for surface water: IS 2296 : 1982 Standard for drinking water: IS 10500 : 1991
Status of Surface Water Bodies of the Madhuban area The water quality of the surface water like ponds and lakes along with the Surface Water Standards (IS: 2296) - Class C (Tolerance limit for stream water used for drinking water sources with conventional treatment followed by disinfection) are given in Table 3.2. It can be seen that the pH of all the water is slightly in alkaline range in Jamunia Gomoh Bridge, which is approximately 3.5 km away from Madhuban Washery (pH=8.45), Ghutway mine water (pH=8.14), Ghutway Village (pH=7.98), Sijua Tank (pH=7.88), Sijua Pond (8.46) and Block II OCP surface water (pH= 8.41) which lies within the prescribed standards. The variation in pH profile of various ponds and surface water bodies in Madhuban area are shown in Fig 3.1.
The water collected from the Block II OCP which is approximately 1Km away from Madhuban washery had the lowest DO (4.3 mg/l) compared to the other surface water bodies. Whereas the DO of other surface water bodies collected from Ghutway Village (6.7mg/L), Sijua Pond (6.3 mg/L), Sijua Tank (6.2mg/L), Jaminua Gomoh Bridge (5.6 mg/l) and Ghutway mine water (4.8mg/L) are much higher than the minimum prescribed DO standards (4 mg/l). The variation in DO profile of various ponds and surface water bodies in Madhuban area is shown in Fig 3.2.
Chloride concentration of water collected from Jamunia Gomoh Bridge, Ghutway Mine water, Ghutway Village, Sijua tank, Sijua Pond and Block II OCP surface water was 17 mg/l, 49 mg/l, 15.5 mg/l, 11.5 mg/l, 18 mg/l, and 43.2 mg/l, respectively which were well within the prescribed standard of 600 mg/l.
The Faecal coliforms of water collected from Madhuban area varied significantly (72 to 128). It was within the prescribed standards. Faecal coliforms in Sijua Pond was higher (128) as compared to the other sources.
The BOD (5day at 200C) was found to exceed the prescribed standard for all the samples (Fig. 3.3). TDS concentration of water in various sources varied from 121-382 mg/l and found to be within the prescribed standards (1500 mg/l). Fig 3.4 shows the variation in TDS profile of various surface water bodies in Madhuban area. Several other parameters such as nitrate, sulphate, Fluoride, etc. were also within the prescribed standards.
Heavy metal analysis of different river and stream water demonstrated that the heavy metals such as lead, cadmium, mercury and chromium were below detection limit (B.D.L). The analysis of the water quality in comparison with the standards (IS:2296) indicates that the different surface water bodies is fit for its

Heavy metal analysis of the drinking water samples indicated that all the heavy metals, i.e., lead, cadmium, mercury, selenium, Boron, Zinc, Nickel, Arsenic and chromium in the mine water were well below the detection limit (BDL). Iron has been detected in the Jamunia OCP mine water in the concentration of 1.6 mg/L and copper was detected in trace amount (0.02 mg/L).
3.4 Noise Level Measurement
3.4.1 Noise level assessment
Sound Pressure Levels (SPL) have been measured by a sound level meter (Model: Lutron SL-4001). Since loudness of sound is important for its effects on people, the dependence of loudness upon frequency must be taken into account in environmental noise assessment. This has been achieved by the use of A-weighting filters in the noise measuring instrument which gives a direct reading of approximate loudness.
3.4.2 Location of noise level monitoring spots The existing mines and other sources of pollution are located in North-east, East, South-east, South, South-west and West direction.

3.4.3 Observations:
Monitoring methodology and noise quality assessment:
A systematic noise quality monitoring was undertaken during day and night time at the monitoring locations using Modular Precision Sound Level Meter (B & K type 2231) during July 2010. In order to evaluate day and night time noise levels, 6 sets of readings were taken at each location within 24 hrs with a gap of 4 hrs in between 2 consecutive readings. Based on these readings average Leq (day) and Leq (night) and background levels (L90) for both day and night time were computed. The average noise levels at the site during day and night time with background noise levels was as presented in Table No. 3.30. The same observations are discussed below under three categories:
Industrial area The average Leq levels in one industrial area i.e., Block 2 office are within the range of 68.8± 2.1 dB(A) and 62.25± 1.5 dB(A) during day and night time respectively. As such, both the day and night time noise levels (Leq) were within permissible norms of 75 &70 dB(A) respectively. The Average background levels, i.e., L90 were within the range of 63±2.3 to 61.5±2.7 dB(A) for day and night time respectively. Commercial area The average Leq levels in one commercial area i.e., Baghmara police station are within the range of 69.7± 2.5 to 59± 1.8 dB(A) during day and night time respectively. As such, the day and night time noise levels (Leq) were within permissible norms of 65 &55 dB(A) respectively. The Average background levels, i.e., L90 were within the range of 64.3±3.2 to 60.1±1.9 dB(A) for day and night time respectively.
Residential area
The average Leq levels in five residential areas such as Khanoodih village and Gutway village are within the range of 49.2 ± 4.2 to 48.4 ± 3.2 dB(A) during day and 40.2 ± 1.8 to 40 ± 2 during night time respectively. As such, the day and night time noise levels (Leq) were within permissible norms of 55 & 45 dB(A) respectively. The Average background levels, i.e., L90 were within the range of 48.7±3.5 to 45.5±2.8 dB(A) and 38.4±2.8 to 35.5±2.6 for day and night time respectively.

3.5 Soil Quality Studies 3.5.1 Laboratory testing of soil
The soil samples were collected by ramming a core-cutter into the soil up to a depth of 90 cm. The samples were then homogenized and packed in a Polythene plastic bag and sealed. The sealed samples were sent to the laboratory for analysis.
Regular monitoring of soil quality is being carried out in the existing Madhuband
Washery at environmental laboratory of BCCL. Although in order to assess the
fertility status w.r.t physical, physico-chemical and micro-nutrient parameters for
six different locations data generation has been carried out by ISM, Dhanbad.
Analysis result in respect of above samples of soil collected from different
locations of core & buffer zone have been analysed and shown in Table No 3.32 3.5.2 Frequency of Soil Sampling
Soil Sampling was carried out at six different locations once a month for each site during the study period of April’10, May’10 & June’10.

3.5.3 Observations
The results of physico-chemical parameters are given in Table 3.32. The average pH value of soil samples varied from acidic (5.47) to alkaline (8.55), electrical conductivity ranged between 0.12 and 1.16 mmhos/cm revealing significant variation in soil water solution. Further, high moisture content in forest and agricultural soils revealed dominance of silt and clay articles and significant organic carbon (1.83-4.00 %). However, barren land and OB dump showed low moisture content and organic carbon indicating lack of clay particles and vegetation. These biogeochemical factors may be responsible for week cation exchange capacity in barren lands and OB dump. Further, in a few mine spoil samples, occurrence of high organic content was observed due to presence of coal dust that might be responsible for high degree of heterogeneity in the study area. The concentration of available nutrients in forest and agricultural lands were greater than that of barren lands and OB dump samples. The characteristics of the agricultural soil showed that though it was in the mining area, it had good fertility status. Moreover, the properties of forest soils were relatively better as compared to the agricultural soils.
3.6 Socio- economic profile 3.6.1 Socio-Economic Scenario of Madhuban Area
The descriptions and projections of social and economic conditions were carried out for Madhuban area the core zone (Madhuban Washery) and buffer zone. The study was concentrated in the buffer zone area, as there is no village in the core zone no resettlement & rehabilitation (R&R) is involved in this project. Socio-economic Scenario Socio-economic profile of the study area is based on the data available from 2001 Census Report. The Socio-economic profile of the buffer zone of the project is based on Demographic Survey done by ESE, ISM, Dhanbad, during the month of June, 2010. In addition a systematic socio-economic survey was carried out to develop socio-economic scenario related to demography, health and food, access to education facility, occupational and income pattern, educational status, etc. This has been done on the basis of secondary data as well as a sample survey of the population of the area. The census data was obtained from the Census Office, New Delhi.
The data revealed that the total population of the Madhuban area according to 2001 census is 106282. Out of total population 106282 the male population is 56499 and female population is 49783. The total numbers of households are 20987. The socio economic status of any area is influenced by various factors and therefore it was necessary to identify the main factors influencing the socio-economic profile of the population in the region. In order to initiate the process,

the team members started interacting with some local people at Madhuban with the help of the revenue officials as per the arrangement with the Tehasildar. The general public in the area was initially reluctant to share their feelings regarding their socio-economic status. They were apprehensive about the objectives of the study. But, after persuasion and proper briefing they provided the team members some basic information, which was useful for the survey.

Social Problems
The main social problem of Madhuban area is unemployment, which has further given rise to social evils like poverty and illiteracy.
Agriculture
Agriculture mostly rain-fed, single-crop rice - is not significant in the Madhuban, where the lack of irrigation limits the scale and diversity of agricultural activity and its potential for growth. Within the coalfield agriculture is limited almost entirely to the subsistence farming of rice and vegetables. Most of the villages have some brick making activity.
3.7 Flora and Fauna 3.7.1 Introduction
Biodiversity Survey of Madhuban Washery
Flora Most of the Madhuban Washery is covered with tropical deciduous forests. Thirty four plant families with 67 species were found. The Madhuban Washery region exhibits considerable variation in plant diversity perhaps as a result of small changes in elevation, coupled with the historical differences in land use. As such, efforts have been made to study the pattern of tree diversity and abundance in the tropical deciduous forests in the Madhuban Washery region.
Method
A representative study of flora was conducted at three sites, each site having ten quadrats of 10 x 10 m2 size, in dry tropical forests of Madhuban Washery region as shown in Table No. 3.35. The sites were selected on the basis of field observations to represent entire range of conditions in terms of canopy cover and disturbance regimes. The most widely used sampling techniques for vegetation analysis involves quadrats in which individual species can be counted and measured. This quadrat technique was applied to communities of plants occupying areas ("stands") of two-dimensional habitat space (e.g., terrestrial plant communities). Random sampling was done in the Madhuban Washery region. All plant species were identified by their botanical names.
In sampling communities of the plants species, the number of individuals, their spatial distribution and frequencies of occurrence were determined. The area covered by individuals was measured by considering the diameter or circumference of the trunk at breast height (1.37 m) and the basal area (cross-sectional area of the trunk) determined with a hand calculator. The basal area or cover value of individual tree species was recorded by quadrate number and

200310002 69
species in a data sheet. The frequency of occurrence of a species is provided by the number of quadrates that contain the species. In summarizing quadrat data, density, dominance, and frequency values were determined for each species. Density refers to the number of individuals per unit area, dominance to the basal area or crown cover per unit area, and frequency to the number of sample plots containing the species. For a particular species, these values may be expressed either in an absolute form or as relative density, relative dominance, and relative frequency, which show the percentage of the individual species value with respect to the total or all species. Relative values for density, dominance, and frequency can be combined into a single Importance Value Index (IVI).
These values are calculated by the following equations: Total number of individuals of one species Density = -----------------------------------------------------
Total number of quadrates studied Relative Density = (Density for a species/Total density for all species) x 100 Basal Area = πr2 = π (d/2)2
Where, d = Diameter at breast height (DBH) and r = radius
Total basal area of species Relative Dominance = -------------------------------- x 100 Total basal area of all species Frequency= Total number of quadrants in which species occur/Total number of quadrats studied Relative Frequency = Total frequency values of one sps/Total frequency values of all species Important Value Index (IVI) = Relative Frequency + Relative Density + Relative Sum of first three relative values have been used to obtain an IVI. During sampling, number of individuals of each species were counted and their diameter taken at DBH (Diameter at Breast Height, i.e., 1.37 m) level. A few individuals of species had more than one stem, so sum of the diameter of all stems were taken as individual plant. The number of individuals and their DBH values were used in quantification of community structure and composition. The number of individuals and number of quadrates were used in analysis of frequency, density and their relative values, while diameter at breast height resulted into quantification of basal area and relative dominance of each species. However, these features alone could not reveal the ecological dominance of any one species. To overcome the narrow significance of frequency, density and basal area alone, the IVI of each species was calculated. The IVI was calculated on the basis of 300% because it is sum of three quantitative parameters. All species were common species and could not be classified as Schedule species (as per Wild Life Protection Act, 1972).

During the survey, adult individuals (>30 cm diameter) of 17 native species of angiosperms were recorded. All sampling sites were made up of the core species plus the additional species specific to each site. The results of quantitative parameters are given in Tables 5.1 to 5.3. The relative values of frequency, density and basal area, and IVI indicate that the structure and function of tropical deciduous forests in Madhuban Washery are dominantly controlled by Madhuca indica, which is a member of Sapotaceae family. The next dominant species was Butea monosperma, a member of Fabaceae family.
The study area represented different communities in terms of species composition. The diversity index, i.e., Shannon-Wiener Index, varied from 2.39 to 2.55, which revealed that the forests were moderate in species richness and lower in stem density and basal area. Across sites, the diversity components and tree density were positively related with total tree basal area. A positive relationship between basal area, tree density and species diversity is an important characteristic of the dry forests, where recurring disturbances do not permit concentration of biomass or stems in only a few strong competitors.
At some sites, there was a greater variation in basal area, which can be attributed to patchy distribution of stems and resultant blanks. Therefore, to enhance the tree diversity of these forests, the variability in tree basal area should be reduced by regulating local disturbances. Conservation activities, particularly fuel wood plantations near human settlements, deferred grazing and canopy enrichment through multi-species plantations of nursery-raised or wild-collected seedlings of desirable species within the forest patches of low basal area, will be needed to attain restoration goals, however, reforestation program will have to be made attractive to the forest-dwelling communities.
The core species, i.e., Madhuca indica of the region occur throughout and can be found in any of the site types (plains forests, basin etc.). It is commonly encountered and as such this can be considered to be the species, which form the backbone of the common ecology of the area. It is the generalist species. Other species may be common within one or two of the specific site types but they are absent from other sites and therefore they must have in relation to the core species a peculiar need or adaptation. In the study region, the Madhuca indica comprises moist savanna and moist mixed deciduous types of forests with adequate regeneration capacity.

Fauna The extensive and dense forests of Madhuban Washery harbour a large number of fauna. Table 5.4 provides the data on animal diversity in forests of the study area. Faunal survey was conducted both by direct (birds, insects, amphibians, reptiles) and indirect (wild animals, larger mammals and snakes) methods. The indirect method involves verbal interaction with local people from different villages of the area. For the study of soil organisms, direct sampling methods in the form of hand-sorting and dry-sieving from soil monoliths were conducted. Smaller soil animals like arthropods, annelids, snails and slugs were identified in the laboratory following authentic hand books. Information pertaining to the migratory route of the birds and wild animal corridors were ascertained from the verbal interaction with the locals. The fishes, amphibians and water snakes are the major aquatic fauna. The terrestrial fauna includes common invertebrates and vertebrates.

CHAPTER - 4
ANTICIPATED ENVIRONMENTAL IMPACT ASSESSMENT & MITIGATION MEASURES
4.0 INTRODUCTION
There would be some changes in various environmental parameters due to operations associated with the proposed washery. The impact arising out of project operations is dependent on magnitude or extent of mining, extent of infrastructural facilities, environmental profile and characteristic of environment.
4.1 IDENTIFICATION OF IMPACT
Identification of impact is an important task in any EIA study. This helps in focusing attention upon relevant environmental parameters and relating them with the activities involved. As far as washery projects are concerned, the following parameters are important in the Environmental Impact Assessment.
1. Socio-economic Impact 2. Impact on land use 3. Environmental & ecological factors * Ambient air quality * Water quality * Noise * Soil condition * Flora & Fauna 4. Impact on Meteorology 5. Hydrogeological aspects 6. Hazard assessment

200310002 76
4.2 SOCIO-ECONOMIC IMPACT
Within the delineated area of core and buffer zones for this project, it is not expected that any major change in the social structure of the area would take place due to this project, since there is an ongoing project of Madhuband Washery and the society of buffer zone is in fully stabilised state in the existing mining and industrial environment of the area.
4.2.1 Population
In general, the average population density of Madhuband Washery in Block-II Area has been found that 5 to 7 persons are in a family. Single member unitary families were only 3 and the most numerous persons per household family comprising thirteen members in a household was only one.
4.2.2 Occupation
Coal mining dominates the economy of the study area as well as district as a whole. The Coal Mining and allied activities like coal washery are the main source of direct and indirect employment and income for the working population of the area. As a consequence, any significant change in the level of mining and allied activities like coal washeries have significant ramifications for local business opportunities and the direct and indirect incomes and employment they provide. Occupation distribution pattern already shown vide Table -3.34.
4.2.3 Amenities
The existing amenities in respect of educational, medical, drinking water supply, communication, electric supply and post & telegraph facilities which are presently being utilised by the existing population of the buffer zone is not expected to be strained further due to the reason that further immigration in this area, as on date is not expected.
However, any development in the existing facilities can never be ruled out keeping in view the rural development programme of BCCL and State Govt. / Central Govt.
4.2.4 Socio Economic Measures No re-settlement and rehabilitation(R&R) is involved in this project.

200310002 77
4.2.4.1 Secondary Employment Opportunities
Coal mining and allied activities dominates the economy of the study area as well as district as a whole. The Coal Mining and the activities associated with coal mining are the main source of direct and indirect employment and income for the working population of the area. As a consequence, any significant change in the level of mining activity will have significant ramifications for local business opportunities and the direct and indirect incomes and employment they provide. The proposed coal washery project will enhance the direct and indirect employment an add to the total income of the working population of the area.
4.2.4.2 Organisation
At the Area level, a rehabilitation cell headed by the Chief General Manager of the area & supported by the personnel from various other departments like Estate, Personnel, Finance, Civil Engg. etc. is existing.
4.3 IMPACT ON AIR QUALITY
The existing air quality levels are within the prescribed CPCB limits for coal mines. However, expansion of Washery and allied activities in Madhuband Washery and the adjoining active opencast mines will have impact on air quality. The main sources of air pollution are :
Under normal conditions, the levels of pollutants in the ambient air is likely to remain below the prescribed limits. However, if pollution control measures as suggested are not implemented, the values may increase considerably.
Besides mining activity, domestic coal combustion in adjoining mines and other indistries may also contribute towards increase in local air pollution, due to smoke and SO2. The peak period of domestic pollution evidently are morning and evening. During winter due to inversion conditions the situation may become worse resulting in poor visibility. With sunrise pollutants will start dispersing along the prevailing wind contributing towards downward locations.
This existing ambient air quality of core zone and buffer zone are well under the influence of entire activities related to coal mining and operations of Madhuband coal Washery and related activities in buffer zone like traffic movement on non metalled, damaged road etc. It is therefore, not expected that now there will be any further enhancement in the existing concentration of the pollutants viz, SPM, SO2, and NOX in the ambient air of core and buffer zone.
However, during monsoon period the concentration of SPM may go much below the permissible limit in the core and buffer zone of the project area.

4.3.1 Air Quality Impact Prediction
Air Quality Model
The effects of air pollutants upon receptors are influenced by concentration of pollutants and their dispersion in the atmosphere. Air quality modeling is an important tool for prediction, planning and evaluation of air pollution control activitiers besides indentifying the requirements for emission control to meet the regulatory standards. The efficient management of air quality requires tlhe use of modeling techniques to analyse the patterns of pollutant concentrations from many individual sources of air pollutants operating simultaneously. Models for regional concentration patterns are based on “emission inventory” data for the region, and on standard meteorological observations assumed to be representative of the entire region. Various attempts have been made to establish empirical relations to predict the dust emission charactertistics for mining operations. These relations may give only a rough estimate of the total dust emission and provide no information about the contour of the dust plume. The generation rate of the contaminants for most mining operations /coal washry cannot be previously determined by empirical relations because there is a high degree of variance in the way such operations are conducted in different mines/coal washeries. Nevertheless, the empirical relations provide the first hand information to the health workers, administrators, planners and engineers for the development to dust control strageties. A model namely ISCST3 Version 02035, of USEPA has been used to predict the air quality of the core and buffer zone of the study area due to mining/coal washery operations in proposed project of Madhuband washery for 5.0 MTY. The dust emission level from mining operations/coal washery are based on USEPA publications and the findings of a MOEF funded Research Project undertaken by CMRI, Dhanbad for estimation of emission factors.
4.3.2 Air Quality Prediction
The air Quality Impact Prediction has been done by using the ISCST3 Version 02035. Air Quality Model of USEPA. Estimation for increase in SPM, RPM, NOx and SO2 at the existing Ambient Air Quality Stations, chosen for the purpose of baseline AAQ data generation, has been done with help of the above model. The impact due to existing Madhuband Washery and other activities has already been considered in the base line AAQ study. The total predicted emission of pollutants has been arrived at considering the emissions from present mining /coal washery activities in the area and from future mining/coal washery activities.

Indentification of sources of TSP and Gaseous pollutants. The main sources of air pollution with regard to Madhuband Washery for the purpose of estimation of increase in SPM, RPM, SO2 and NOx were identified as :- 1. Transport of coal from mines to the Washery. 2. Coal handling Activities inside the project area. 3. Washery Process 4. Storage of Rejects 5. washed coal transportation from wahery to Railway Siding. 6. Storage and Wagon loading of coal at the Railway Siding. Receptors The existing Ambient Air Quality Stations (1 in core zone and 5 in the Buffer zone), chosen for the purpose of baseline data generation by ISMU, Dhanbad, have been treated as receptors for estimation of increase in SPM.

4.3.3 Air Quality Modeling (Madhuband Washery)
Air quality modeling was done using ISCST3 Version 02035 of USEPA for the prediction of air pollution in terms of dust concentration and deposition in around the leasehold of the Madhuband Washery.
It was developed in the USA and is effectively used in computing the dust concentration and deposition from the different dust generating source like point, line and area sources.
The model is used to process the maximum of 121 sources and 1200 receptors for a given set of meteorology data. The model can give output for 1 hourly average, 3 hourly average, 8 hourly average and 24 hourly averages as required by the user.
Procedure
The emissions from all sources for different particle size were calculated. The co-ordinates of the different sources were also found. The meteorological data generated during the base line study of the area has been used in the model.
For calculating the emission from the different activities, the empirical equation, developed by the USEPA 1998 has been used. Estimation of Dust generation by various mining activities are given in Table-4.5.

SPM Generation at Coal Washery
1 a b
Raw Coal Receiving point Total coal received in TPD = 16666 TPD The dust generated at receiving point due to unloading from dumpers = 16666 TPD x 0.033 kg /te = 550 kg / day. Applying a control factor of 50 %, the quantity of the effective dust generated = 275 kg/day. Dust generated at inlet point of conveyor belt = 16666 TPD x 0.075 kg/ te = 1250 kg/day. Application of control factor of 90%, the quantity of the effective dust generated = 125 kg/day.
2 Crusher House The dust generated during crushing by feeding to the Rotary Breaker = 16666 TPD x 2.0 kg /te = 33332 kg / day. Application of control factor of 90%, dust generated = 3333 kg/day
3 Receiving at Conveyor to the Tube Stacker Dust generated at inlet point of conveyor belt = 16666 TPD x 0.075 kg/ te = 1250 kg/day. Application of control factor of 90%, the quantity of the effective dust generated = 125 kg/day.
4 Unloading at Tube Stacker Point/Ground Hopper Dust generated at unloading point of conveyor belt = 16666 TPD x 1.15 kg/ te = 19166 kg/day. Applying control factor of 90%, dust generated = 1917 kg/day
5 Loading onto Conveyor for washing Dust generated at inlet point of conveyor belt = 16666 TPD x 0.075 kg/ te = 1250 kg/day. Application of control factor of 90%, the quantity of the effective dust generated = 125 kg/day.
6 Outlet from Washery to Conveyor upto Railway siding As the process of washing facilitates 100% removal of dust, there will be no effective dust produced at this point.
Total SPM generated from washery due to above activities=275+125+3333+125+1917+125 = 5900 kg/day Area of Coal Washery=230000 m2 Emission factor for Coal Washery= 5900*1000/230000*24*60*60= 2.96*10-4 gm/m2/s

Table No. 4.9
Predicted concentration of SPM at different station in (µm/m3).
Station code Station Name Incremental SPM (µg / M3) A-1 Madhuban washery (Behind GM
office) 60.2
A-2 CISF Camp 9.1 A-3 Ghutway village 2.6 A-4 Khanoodih village 52.2 A-5 Nehru Nagar 5.3 A-6 Indian School of Mines (CME
Building) 19.5
4.4.4 Observation of predicted impact
By observing the result of the model we can say that the project will not have any significant impact as the increase in the dust concentration is estimated to be marginal. It can be seen from the above table that the maximum values of SPM are much less than the permissible values specified in NAAQS. The 95% values in summer season of SPM/RPM is also much below the permissible limits. From the Air Quality Modeling results and also by analyzing the data generated for the Environment Baseline Study it can be concluded that Madhuband Washery Project shall not have any significant impact in the increase in pollution level. Table 4.10 shows that air pollution level will not go very high due to operation of the project and also it will not stress or shock the supportive and assimilative capacity of the air basin of the environment. The existing level of SPM in the monitoring stations AQ1 , AQ2, AQ3,AQ4, AQ5 & AQ6 are high due to the existing mining activities in the near by areas. The predicted incremental values of SPM concentrations in the monitoring stations lying in the buffer zone, namely AQ3, AQ4 & AQ5, are on higher side since they are situated in the down wind direction of the core zone. However the total predicted SPM concentration at the monitoring stations are well below the permissible limits.
The ISCST3 model was also run for estimation of SO2 and NOX and the incremental values at the receptors in Core and Buffer Zone were found to be negligible

112
Isopleth of the predicted concentrations has been shown in Plate No.9.
4.4.5 Air Pollution Control Measures
Following measures are proposed in order to bring down the SPM concentration level below the permissible limit as because this will be the only component, which may be found exceeding the limits in core zone during the dry season:-
i) All permanent roads of the project will be maintained to reduce
dust due to vehicular traffic.
ii) Regular and routine maintenance of diesel operated machineries will be carried out to minimise emission of noxious gasses.
iii) Frequent spraying of water on unmetalled roads, service road.
iv) At the points of dust generation, water sprinkling / spraying shall be done.
v) Thick greenery will be developed in and around the project area
wherever land is available to prevent propagation of dust with wind.
4.5 IMPACT ON WATER QUALITY
The core zone and buffer zone of the project are situated in such areas where extensive coal mining activities either opencast or underground have been going on since decades. Under these circumstances, natural water courses, surface ponds, wells and the underground flow of water all are under the influence of opencast and underground mining activities in their respective areas. . As far as coal washery is concerned, there will be no any impact on water quality since the washery operations are to be run on zero discharge basis.
4.5.1 Effect on Ground Water Quality
The proposed washery will have closed water circuit and thus will have zero discharge to the outside environment. However there may be discharge outside during heavy storm and their effect on ground water will be negligible. Storm water will be challelised and sampling done during the period to monitor its pollutant level and action will be taken accordingly.
4.5.2 Source of Effuent
Proposed Madhuband NLW Washery EIA_EMP TEXT(FINAL) Job No. 200310002
113
The proposed washery will have closed water circuit and thus will have zero discharge to the outside environment. Thus there will be no of effluent from the premisses. As such there is no likelihood of pollution of water due to opeation of the washery.
4.6 IMPACT ON LAND The total land requirement for the project has been assessed as 23 Ha. Green belt will be developed around the proposed washery and the service roads . The land belongs to BCCL. The layout of the plant with green belt development is given in Plate-no:10.
4.7 IMPACT ON NOISE LEVEL Noise sources The source of noise in the plant include.
Crushing operation
Operation of crusher will produce noise. It is proposed to enclose the crusher in a R.C. enclosure as described later. As such noise produced by crusher will be mitigated. Belt conveyor Operation of belt conveyor will produce noise.
Level of noise produced by belt conveyor has been assessed to be 70 db (A) at a distance of 3m away. Belt conveyors will be enclosed to mitigate the pollution.
Washing Operation.
Washery operation will also produce noise.Since all equipments are to be housed in building hence noise produced by the operations of equipment will be mitigated. Vehicular movement: The movement of vehicles for raw coal transportation will be restricted to day time as far as possible, well maintained and the roads will be maintained for their smooth plying. There is no other noise producing source in the plant premises. A green belt (20 m wide) having 2 rows of trees provided at periphery of the plant site will also help noise abatement fom the plant area.

4.8 IMPACT ON BIO-ENVIRONMENT The plant site is free from forest cover. As such construction of the plant and
its infrastructure will not degrade forest or habitat. Project construction and operation are not likely to affect bio-environmental. In addition, after proposed reclamation and afforestation of degraded land there will be a certain increase in the greenery of the core zone which is at present barren. With availability of greenery as host, guest flora and fauna will automatically come up which will improve the ecology and aesthetics of the area.
4.9 IMPACT ON SOCIO-ECONOMIC ENVIRONMENT The land required for the project belongs to project proponent and is free form
any human habitation. As such construction or operation of plant is not likely to have any adverse impact on socio-economic profile of the area.
4.10 IMPACT ON METEOROLOGY Meteorological data for the last few decades have been collected from
nearest IMD station at Loyabad, Dhansar Rescue Station and Indian School of Mines, Dhanbad.
The Project Area, which falls in Dhanbad district of Jharkhand State, is
situated in the Damodar river basin. As because the area is nearer to Bay of Bengal, its climate is under the influence of the wind conditions such as, the surface distribution of atmospheric pressures, upper air circulation caused by weather condition, inflow of different air masses etc. that originates from the Bay of Bengal. The inflow of western disturbances and tropical depressions that originates from Bay of Bengal cause rainfall in the area.
The Jharia Coalfield region has a tropical monsoon type climate. Air on land
originate from the west with little clouds during the month of December that continues upto to February. Air originating from sea from the east and the south brings about 80 to 85% of annual rainfall distributed in the month of June to September. The broad seasonal variation for the year on account of the above wind movement are as under :
i) The winter season exists from November to February with a fall in
temperature upto 5 degree C. Clear bright sky with occasional rain during January and February, are observed in this season.
ii) The summer season prevails from March to June with gradual increase in
temperature and moisture. The highest temperature experienced ever has
Proposed Madhuband NLW Washery EIA_EMP TEXT(FINAL) Job No. 200310002
115
been 48 degree C. Afternoon thunder storm is frequently observed causing poor visibility in May.
From later half of the month of June the rainy season starts and it ends in the
first half of October. The south-west monsoon brings about the major precipitation. The maximmum rainfall recorded in this region is 331 mm in 24 hrs. during September '95. Before the onset of monsoon, the thunderstorm is associated with dust storm. The land ward movement of depression towards west from the head of the Bay of Bengal, results in widespread rainfall as well as local heavy rainfall including cloud bursts.
4.11 ENVIRONMENTAL POLLUTION MITIGATION MEASURES The project related activities may have some impact on environment in study
area in order to take care of the same, appropriate mitigation measures are recommended below.
4.11.1 Mitigation Measures for Air Quality
i) Coal crushing Coal is proposed to be sized by crushing at two stages. This is a source of
dust generation it is proposed to cover the crusher with enclosure. A dust extraction system would be provided to collect all dust generated during the crushing operation. The dust should be collected in bags. Subsequently these collected bags would be disposed off appropriately.
ii) Road Transport Coal transportation by road is likely to be a major source for generation of
particulate matter. In order to mitigate the impact of this, following recommendations are given:
a. Widening & Strengthening of Transport Road
The road that has been identified for transportation of raw coal and product coal will be widened & strengthened keeping in mind the current traffic density and increase in traffic density due to project. This will ensure that existing traffic facilities are not affected.

Various sources of water pollution and the measures taken to prevent water
pollution due to such sources are as follows :
Proposed Madhuband NLW Washery EIA_EMP TEXT(FINAL) Job No. 200310002
124
Domestic Effluent
Entire domestic effluent which will be coming out of residential buildings and service buildings in the project area are proposed to be treated in septic tanks and soaked into soak pits. No such discharge will be allowed to enter into the surface water courses directly.
Industrial Water Discharge
The water required for industrial purposes other than for spraying result into waste water discharge containing mobil, grease, etc. This water will be put into a closed circuit (the collected water at the floor of sump will be pumped to the settling tank where suspended solids will get settled). The clear water after sedimentation will be reused for water sprinkling, plantation etc. Workshop effluents will be discharged through oil and grease trap and sedimentation tank and the water thus regained after separating oil and grease will be reused. Expenditure for above arrangement will be made by revenue budget of the project.
Ground Water From Washery
The ground of washery premises will be allowed to accumulate in the sump. This water will be used to fulfill the industrial water demand.Thus, there does not exist any threat of pollution of water to natural water course.
PROPOSED RAIN WATER HARVESTING PLAN FOR MADHUBAN WASHERY
Rain Water harvesting is collection and storage of rainwater that runs off on
natural and man-made catchments area. The rain water within the project area will be
accumulated in the dip most portion to the north-western side of the project and it will be
pumped out into earthen water pools developed on the surface which will not only be
helpful in re-charging the ground water of the area but will fulfill the non-drinking water
demand of near by inhabitants also.
Rain water will automatically gravitate to the main sump because of the gradient.
The capacity of the main sump will be such that maximum rainfall in a particular day can
be accumulated. It will also take care of any unforeseen situation due to total failure of
pumping activities during monsoon.
Rain water will accumulate in small ponds and a rain water sedimentation sump.
The over flown or excessive rain water draining out through the garland drains or small
Proposed Madhuband NLW Washery EIA_EMP TEXT(FINAL) Job No. 200310002
125
drains specially constructed to avoid inrush of water. The accumulated water in ponds is
conserved for tree plantation in the existing reclaimed area. This will also prevent the
erosion of soil and gully formation in the area.
Artificial Recharge to Ground Water The following rainwater harvesting and ground water recharge methods are proposed to
be taken up in the proposed Madhuban Washery.
Storage tanks: For harvesting the roof top rain water from different buildings of the
project, storage tanks will be used. These tanks will be constructed on the surface as
well as under ground. The size of tank depends upon availability of runoff & water
demand. After proper chlorination, the stored water can be used for domestic purpose,
plantation etc.
The settling ponds which will be constructed for accumulating fines/ slurry from
washed coal will also help in recharging of the ground water table and aquifers.
Recharge Pits: Recharge pits will be constructed for recharging the shallow aquifers.
These are constructed 1 to 2 m. wide and 2 to 3 m. deep which are back filled with
boulders, gravels & coarse sand.
Trenches: will be constructed when the permeable strata is available at shallow depths.
Trench may be 0.5 to 1 m. wide, 1 to 1.5 m. deep and 10 to 20 m. long depending upon
availability of water. These will be back filled with filter materials.
Abandoned Dug wells and tube wells: Existing abandoned dug wells situated in
nearby villages will be utilised as recharge structure after cleaning and desilting the
same.
Abandoned Hand pumps: The existing abandoned hand pumps situated in nearby
villages will be utilised for recharging the shallow / deep aquifers.
Proposed Madhuband NLW Washery EIA_EMP TEXT(FINAL) Job No. 200310002
126
Recharge wells: Recharge wells of 100 to 300 mm. diameter are proposed to be
constructed for recharging the deeper aquifers and roof top rain water is diverted to
recharge well for recharge to ground water.
Benefits of rain water harvesting and ground water recharging:
1. Will augment drinking and domestic water problem in areas having inadequate water
resources.
2. The ground water level will rise. Water harvesting to recharge the ground water
enhances the availability of ground water at specific place and time and thus assures
a continuous and reliable access to ground water.
3. Mitigates the effects of drought.
4. Reduces the runoff which chokes the storm water drains.
5. Reduces flooding of roads.
6. It improves the quality of ground water in aquifers
7. Soil erosion will be reduced.
8. Greenery will increase.
9. It reduces the power consumption as rise in water levels results in saving of
electricity
Acceptable noise levels and peak particle velocity Assessment of impact of noise nuisance of a workplace can be achieved by comparing the level with TLV prescribed by the DGMS. There are also standards relating exposure time with noise levels from the International Standard Organization (ISO) and American Conference of Governmental Industrial Hygienists (ACGIH). These standards may also be used to assess the impact of noise in workplaces.
The permissible peak particle velocity at the foundation level of structures are given below:
DEVELOPMENT OF GREEN BELT (in Block-II Area)
Thick green belt has been proposed to be developed at Washery, and project roads, etc. to prevent the propagation of sound and also to dampening its intensity. Afforestation in patches as the plantation of saplings is being done in Block-II Area of BCCL. However, so far 1.2 lakh plants have already been planted in different locations in buffer area. This will have some indirect impact on noise reduction/control.
Proposed Madhuband NLW Washery EIA_EMP TEXT(FINAL) Job No. 200310002
127
Promising Species at Washery Site and near by washery Areas:
In selecting a particular set of species the following points will be considered.
1. Species locally grown / naturally growing.
2. Ecologically pioneer in succession and preferably having ability to fix nitrogen.
3. The species existing prior to mining.
4. Fast growing species for providing vegetal cover in a

CHAPTER – 11
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. 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
11.3 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.
Proposed Madhuband NLW Washery EIA_EMP TEXT(FINAL) Job No. 200310002
144
(A) Ambient Air Quality :
Impact on ambient air quality has been limited to 7 stations in the study area. Impact has been assessed using ISCST-III software developed by USEPA. The
locations of monitoring stations are as given below:
- On upwind direction
- On downwind direction
- In core zone
- In cross wind direction
Following air quality parameters have been included in impact assessment.
- Suspended Particulate Matter (SPM)
- Respirable Particulate Matter (RPM)
- Sulphur Di-oxide (SO2)
- Oxides of Nitrogen (NOx)
Incremental value of each parameter due to project activities has been assessed.
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 have 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.
Proposed Madhuband NLW Washery EIA_EMP TEXT(FINAL) Job No. 200310002
145
(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, screaners, conveyors & transfer point. They are mostly to be enclosed in the plants buildings. Hence their impact on ambient environment will be minimal.
(D) 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.
In the study area, there is forest patch on N-E side. An examination of windrose
diagram shows that the prevailing wind direction is from NE to SW. Thus, air pollution caused by the project will not have impact on the existing forest patch on N.E. side.
(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.
11.4.1 AIR POLLUTION MITIGATION MEASURES Following air pollution mitigation measures have been recommended:
(i) Installation of water sprinkling system at the ground coal stock for raw coal.
(ii) Raw coal crushers completely enclosed. (iii) In Coal Handling Plant, water sprinkling system on all transfer points.
Proposed Madhuband NLW Washery EIA_EMP TEXT(FINAL) Job No. 200310002
146
(iv) Belt conveyors handling coal enclosed from side and top. (v) Regular water sprinkling on paved area. (vi) Green Belt along periphery of the plant area. (vii) Tippers carrying raw coal and product coal to be covered. (viii) Green belt along both sides of road.
11.4.2 WATER POLLUTION MITIGATION MEASURES (i) Municipal Effluent generated in service buildings, i.e. rest shelter,
canteen, office etc. would be treated in septic tank. (ii) Industrial Effluent generated in washery plant will be treated in a series
of sedimentation pond. Treated effluent will be recycled for reuse in plant. Thus there will be zero discharge from the plant premises.
11.4.3 NOISE POLLUTION MITIGATION MEASURES (i) Noise generating stationary sources, i.e. crusher, coal handling plant,
etc. to be enclosed. (ii) Coal washing equipments are to be housed inside the building. Thus
noise generated by these equipments will not spread. (iii) Vibrating equipments to be provided with vibration control pads to
reduce vibration and noise. (iv) Green belt around plant area will help in mitigating noise.
11.4.4 BIO-ENVIRONMENT MITIGATION MEASURES (i) The site which has been selected for locating plant is free from forest /
vegetation cover. Thus construction of plant will not affect flora & fauna. (ii) A patch of forest is located on N.E. side of the plant site. This patch is
about 8 Km away. Since this patch is on upwind direction from the plant, air pollution generated by plant operation would not affect level of air pollution in forest patch.
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.
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 are 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.

methods prescribed by CPCB (July 2003). The detailed methodology and measuring
instruments are presented in brief in Chapter 3.
Ambient Air Quality Status of the Study Area is summarized below :
Particulate Matter (SPM & RPM )
The average SPM concentration levels at different locations of industrial area (e.g.,
CISF camp, GM building, were within the range of 381 to 515 μg/m3. These were
within the permissible level of statutory norm. Similarly, the average SPM
concentration levels at different locations of residential, rural and other areas were
within the range of 263 to 450 μg/m3 and were crossing the permissible level of 200
μg/m3 for residential, rural and other areas. At ISM (control site) concentration varies
from 112 to 149 μg/m3 the average concentration was 132 μg/m3 which is below the
standard limit
The average RPM concentration levels at different locations of industrial area (e.g.,
CISF camp, GM building) were within the range of 175to 242 μg/m3 and were within
the permissible level of statutory norm. Similarly, the average RPM (PM10)
concentration levels at different locations of residential, rural and other areas (were
within the range of 140 to 199 μg/m3 and were crossing the permissible level of 100
μg/m3 for residential, rural and other areas. Both the SPM and RPM concentration
levels reduced significantly during the days having maximum rain fall. At ISM
(control site) concentration varies from 54 to 80 μg/m3 the average concentration was
69 μg/m3 which is below the standard limit.
Gaseous Pollutants
The average SO2 concentration levels at different locations of industrial area (e.g.,
CISF camp, GM building) were within the range of 32 to 33 μg/m3. These were
within the permissible level of statutory norm. Similarly, the average SO2
concentration levels at different locations of residential, rural and other areas were
within the range of 24 to 30 μg/m3 and were within the permissible level of 80 μg/m3
for residential, rural and other areas. At ISM (control site) concentration varies from
11 to 29 μg/m3 the average concentration was 22μg/m3 which is below the standard
limit.
The average Nox concentration levels at different locations of industrial area (e.g.,
CISF camp, GM building) were within the range of 32 to 58 μg/m3. These were
within the permissible level of statutory norm. Similarly, the average NOx
concentration levels at different locations of residential, rural and other areas were
within the range of 35 to 51 μg/m3 and were within the permissible level of 80 μg/m3
for residential, rural and other areas. At ISM (control site) concentration varies from

20 to 38 μg/m3 the average concentration was 30μg/m3 which is below the standard
limit.
.
Overall , Significant levels of air pollutants exists in the area with reference to
Particulate Matter (SPM, & RPM ) and gaseous pollutants were recorded high due to
higher background levels due to the emission from the various industrial activities
(Coal mines, Private Coke ovens, coal washeries, and also domestic burning of coal.
