xiii The project authority shall implement suitable conservation
measures to augment ground water resources in the area in
consultation with the Regional Director, Central Ground Water
Board.
The plateau top , where the mining
operation is confided, stands out about
300M above the surrounding valley
areas. The ground water exists at a depthof about 80m .
At present, 4 no. of rain water harvesting
reservoirs development have been
carried out and one more reservoir isbeing developed in the mine lease area
to conserve the rain water. Rainwater
fom these ponds percolate down belowwhich augments the ground water
reserve.Also, action has been initiated to
develop rooftop rainwater harvesting
structures for the office buildings and
infrastructure facilities in the mine leasearea. This will improve the water
availability in the hill, which in turn will
improve the water availability from the
springs originating from thePanchpatmali hill.
Further, the method of Mining & theperipheral barrier all around does not
allow the storm water from within the
mining area to go outside valley areas.
The water thus trapped, percolates down& recharges the ground water.
xiv Regular monitoring of ground water level and quality shall becarried out in and around the mine lease by establishing a networkof existing wells and constructing new piezometers during themining operation. The monitoring shall be carried out four times in
a year, pre-monsoon (April-May) , monsoon (August), Post-monsoon (November) and winter (January) and the data thuscollected may be sent regularly to the Ministry of Environment andForest and its Regional Office, Bhubaneswar, the Central GroundWater Authority and the Regional Director, Central Ground WaterBoard. If at any stage, it is observed that the ground water table isgetting depleted due to the mining activity, necessary correctivemeasures shall be carried out.
It is revealed from a recent study by M/s
RAMKY (in Yr 2010) that the ground
water table atop the hill exists below 80
mtr. from the plateau top, where the
mining activities are going on. Hence
ground water is being monitored in 15
villages around Mines. The latest
results of analysis is presented at
Annexure-V.
xv Appropriate mitigative measures shall be taken to prevent pollutionof the Indravati River, the Vagabvalli river, Banadehar River andKerandi River in consultation with the State Pollution ControlBoard.
The Mine is not having any beneficiation
plant Further, the mine being a zero

to treat wash water from Workshop &
Canteen & the treated water is used for
dust suppression and plantation purpose.
As already explained, rain water (with
sediment) is also not allowed to go out
of Mining areas . Further all the streams
emanating from the Panchpatmali hill
slopes are being monitored and all
parameters are within prescribed norms.
As such in no way the mining operation
affects the river basins which are any
way situated at least 30 KM away .

ii) Short term (5 years) as well as long term (20Years) plans are always kept updated as per the
Guide lines issued by A.P., France, providing for
overall Environment management
considerations.
B)
Peripheral barrier with green belt
around mining area:
More than 7.5 mtr. width of peripheral barrier left all along the
Mined out area with green belt developed over it. This green belt isdeveloped/ maintained 500M ahead of Mining operation.
C) Garland drains around the mining
area:
Garland drains are being maintained ahead of mining operation to
drain surface run-off water to the valley following natural gradient.
D) Drainage control within the mining
area
Movement of mine faces are being carried out systematically as per
mine plan following the contour lines such that the faces have self
draining slopes. Rain water in the mines from these self draining
slopes are being collected in two sumps within the mined out area.Water from the sumps mostly percolates down through thick clay
layer which acts as a filtration bed. Three barriers/bunds are
provided to arrest / restrict flow from sumps at mined out area .
2.
A)
Mine Rehabilitation :
Preservation & use of Top Soil
i) During initial mining activities about 1.0 lakhtonnes of top soil was excavated and preserved
separately which was used in the back-filled
areas, Overburden dumps, adjacent slopes ,
nursery development and afforestation activitiesby the end of year 1989-90.
ii) At present top soil is being excavated separatelyand directly used in the reclamation area.
B) Systematic development of minedout area for land restoration:
Mining activities are carried out systematically as per a long term/short term mining plan. Overburden & Top soil stripped ahead of
bauxite mining faces are dumped in backfilled/ Mined out area
created continuously as the mining proceeds with complete
exploitation of Bauxite. Dumped lateratic overburden is levelled
before putting topsoil which also subsequently leveled/ dressed toprepare the reclaimed land ready / suitable for plantation with
necessary provision of benches and terraces. As such back filled
area development/ land reclamation is an integral part of mining
process and goes hand in hand with bauxite mining. Total areareclaimed so far, following the said procedure is 199 Hects.

C)
Land development with forestry &
water basin :
As explained above , the backfilled area is developed with proper
benching and drainage system to maintain slope stability. As such,
the mined out area is totally reclaimed with backfilling, plantation
and water basins at strategic points for ensuring proper drainageAfforestation is carried out with selected forest and fruit bearing
species in this back-filled areas. Till date total 199 hects of mined
out area reclaimed, has been planted with 4,92, 200 nos of trees..
3. Treatment of Over-burden and soil
dumps.
At present total overburden(laterite & top soil) removed is being
used for backfilling in mined out area obviating needs for further
creation of overburden dumps. This process has started since the
year 1989-90 .
All soil dumps of construction phase have been suitably stabilised
by undertaking necessary soil conservation measures .Further these
areas with plantation done , have now been covered with good
vegetation, where growth of vegetation is satisfactory.
4. Dust Suppression Dust suppression in the mining area is being carried out by watersprinkling using mobile tankers. In addition to this an auto
sprinkling system has been installed/ maintained all along the
central /Main haul road .
All Drilling machines are provided with efficient dust extractors
and or wet drilling arrangements. Dust extractors and hoods are alsoprovided at transfer points in Crushing and Conveying System apart
from provision of Covers all along the Conveyor System (14.6 km
long) to restrict the dispersion of dust. In the crusher house ,an
efficient dry fog system is provided for suppression of dust at ROMhopper and Transfer points. Employees are provided with personal
dust protection equipment like nose masks, wherever necessary.
5. Control of Noise & Vibration Equipment/ machineries have been selected with least noise &
vibration level and periodic surveys have shown them to be within
limit of TLVs. With the multiple face working, the equipment are
scattered over a vast area, there-by reducing any concentration ofnoise and vibration level exceeding TLV in any particular area.
Operators cabins in different equipment/machineries and at drive
house/crusher have been completely enclosed to reduce noise level.
Vibrations due to blasting is also kept to a minimum by adopting awell designed blasting pattern with sequential blasting by use of
delay detonators or by use of NONEL. As per the study conductedby M/s ISM, Dhanbad & M/S CMRI , the blast vibration falls to an
imperciable limit within a distance of 50-60 metres on hill slope.
Employees are provided with personal ear protective equipmentslike earplug, earmuff wherever necessary.

Adequate sewage systems are provided in the mining complexwhich are being checked regularly. Effluents from the Mechanical
Workshop area is being chanelized through well-designed oil-water
separation tank where oil is collected and the clear water is recycled
for washing of equipments & dust suppression purpose. Also there
is a canteen waste water disposal system designed, constructed andmaintained for environmental friendliness.
7. Plantation activities : Till date we have completed plantation of about 1050 hects within
Mininig Lease hold areas with 27,73,769 nos. of trees of more than70 diff. Species. This includes experimental plantation,
beautification of areas, development of lawns etc.
Development of Nursery and experimental plantation : Mine has
its own nursery and in this high altitude nursery experiments are
being carried out for testing the survibility & adoptability ofvarious types of forest & economical species.
8. Monitoring activities: Monitoring of various aspects of environmental Management Plan
by our multi-disciplinary team & confirmation by various
professional agencies leads to conclude that implementation ofEMP is going on very satisfactorily bringing continuous
improvement of environment.
The followings are the latest observations taken during the period
from October 2011 to March 2012.
