Sub: Parbatpur Coal Mine Project
(1.80 MTPA.) of M/s Eletrosteel Castings Ltd., located in village Talgoria,
Tehsil Chandankyari, District Bokaro, Jharkand- Environmental clearance – reg.
Sir,
This has reference to your
letter dated 01.01.2006 enclosing the application and subsequent letter dated
05.10.2006 on the above-mentioned subject. The Ministry of Environment &
Forests has considered your application. It has been noted that the project is
for opening a new Parbatur Coal Mine
Project for an annual production capacity of 1.8 MTPA over a total lease area
of 865 ha. Of this, 484 ha is agricultural land, 205 ha is wasteland, 132 ha is
grazing land, 1 ha is surface water bodies, and 43 ha is others. There area
no National Parks, Wildlife Sanctuary, Biosphere Reserves found in the 10 km
buffer zone. The project does not involve R&R. Site clearance was granted
on 16.11.2005. River Damodar flows at a distance of 50m to 1500m from the ML
boundary. It is not proposed to modify the existing drainage. Mining will be
both opencast (OC) and underground (UG) by semi-mechanised/mechanised method.
The project includes a Coal Washery capacity for 1 MTPA of washed coal as
ancillary operations. Controlled blasting is involved. Rated capacity of the mine is 1.80 million tonnes per annum (MTPA) of
coal production. Mineral transportation of 4000 TPD of coal is by road (1000 TPD) involving about 350 vehicles
covering a distance of 15 km and by rail (3000 TPD).. Ultimate working depth of
the mine by opencast operations is 92m below ground level (bgl) and 600m bgl by
UG mining. Water table is in the range of 2.76-4.93 m bgl in the core zone and
3.20-6.30m bgl in the buffer zone. Mining will intersect water table. Peak
water demand is 9415 m3/d of water which is met from mine sump/pit
water (8600 m3/d) and from groundwater (100 m3/d). during
construction stage only. The sump water (8600 m3/d) wil be use for mine
operation (5000 m3/d), dust suppression (250 m3/d), domestic use (35 m3/d),
green belt (250 3/d), coal washery (1400 m3/d) and for stowing (1400 m3/d).
Further requirement of water, if any, will be from rainwater harvesting
measures. An estimated 15 Mm3 of OB will be generated of which 9 Mm3 will be
backfilled at the end of mine life, 5 Mm3 will be used for levelling, and 1 Mm3
for strengthening of river embankment. The balance OB will be stored in 2
external OB dumps of a max. height of 60m consisting of 6-10m terraces. Life of
the mine at the rated capacity is 55 years. Public Hearing was held on
05.05.2006. NOC has been obtained on 15.07.2006. Mining Plan has been approved
by the Ministry of Coal on 14.07.2006. Capital cost of the project is Rs. 350 crores.
2. The Ministry of Environment &
Forests has examined the application in accordance with Section 12 of the EIA
Notification 2006 and under the provisions thereof, hereby accords
environmental clearance for the above-mentioned Parbatpur Coal Mine Project of M/s
Electrosteel Castings Ltd. over a lease area of 865 ha for production of coal
at 1.8 MTPA rated capacity under the provisions of the Environmental Impact
Assessment Notification, 2006 subject to the compliance of the terms and
conditions mentioned below:
A. Specific
Conditions
(i)
All the conditions stipulated by
the SPCB in their NOC shall be effectively implemented.
(ii) Mining shall be
carried out as per statuette at a safe distance from the river and any water
body flowing within the lease boundary. At the time of depillaring, protective
bunds and garland drains shall be provided so that no water from the surface
enters the subsidence area and the shaft.
(iii) While extracting
panels in the lower seam, all water bodies in the subsidence area shall be
drained. Dewatering of the old goaves of the upper seam shall be continued as
long as the lower seam is worked to prevent accumulation of large water bodies
over working area.
(iv) Sufficient
coal pillars shall be left unextracted around the air shaft (within the
subsidence influence area) to protect from any damage from subsidence, if any.
(v) Solid barriers shall
be left below the roads falling within the blocks to avoid any damage to the
roads.
(vi) No depillaring
operation shall be carried out below the roads and village area found within
the lease.
(vii) Regular monitoring of
subsidence movement on the surface over and around the working area and impact
on natural drainage pattern, water bodies, vegetation, structure, roads, and
surroundings should be continued till movement ceases completely. In case of
observation of any high rate of subsidence movement, appropriate effective
corrective measures should be taken to avoid loss of life and material. Cracks
should be effectively plugged with ballast and clayey soil/suitable material.
(viii)
Garland drains (size, gradient and
length) around the safety areas such as mine shaft and low lying areas and sump
capacity should be designed keeping 50% safety margin over an above the peak
sudden rainfall and maximum discharge in the area adjoining the mine sites.
Sump capacity should also provided adequate retention period to allow proper
settling of silt material.
(ix) OB should be stacked
at the two earmarked external OB dumpsite(s) within ML area and shall have a
maximum height of 60m only and consist of benches of 6-10 m each. The ultimate
slope of the dump shall not exceed 28o. Monitoring and management of
existing reclaimed dumpsites should continue until the vegetation becomes
self-sustaining. Compliance status should be submitted to the Ministry of
Environment & Forests and its Regional office located at Bhubaneshwar on
yearly basis.
(x) Catch drains and
siltation ponds of appropriate size should be constructed to arrest silt and
sediment flows from soil, OB and mineral dumps. The water so collected should
be utilised for watering the mine area, roads, green belt development, etc. The
drains should be regularly desilted and maintained properly.
Garland drains (size, gradient and length) and sump capacity should be
designed keeping 50% safety margin over and above the peak sudden rainfall and
maximum discharge in the area adjoining the mine site. Sump capacity should
also provide adequate retention period to allow proper settling of silt
material.
(xi) Dimension
of the retaining wall at the toe of the dumps and OB benches within the mine to
check run-off and siltation should be based on the rainfall data.
(xii) Crushers at the CHP should be
operated with high efficiency bag filters/water sprinkling system should be
provided to check fugitive emissions from crushing operations, conveyor system,
haulage roads, transfer points, etc.

of Environment & Forests and tot eh Central Pollution Control Board
quarterly within one month of monitoring.
(xix) The
Company shall put up artificial groundwater recharge measures for augmentation
of groundwater resource. Any additional water requirement for mining operation
shall bemet from rainwater use only. The project authorities should meet water
requirement of nearby village(s) in case the village wells go dry due to
