NUASAHI CHROMITE MINES
M/S INDIAN METALS & FERRO ALLOYS LTD.
COMPLIANCE OF THE CONDITIONS OF ENVIRONMENTAL CLEARANCE FOR THE
PERIOD FROM APRIL'12 TO SEPT'12.
SPECIFIC CONDITIONS
(i)
Condition : Top soil should be stacked properly with proper slope at earmarked site(s)
with adequate measures and should be used for reclamation and rehabilitation of mined
out area.
Compliance : There is no top soil generated from Underground mines and the
availability of top soil is not expected from Underground mine. However, the top soil is
being procured from outside for fruitful utilisation of plantation purpose.
(ii)
Condition :Two external OB dumps exist OB should be stacked at earmarked dump
site(s) only. The total height of the dump (s) should not exceeds 10-15 m keeping
maximum overall slope of not more than 28 0 .
Compliance : This has already been complied as per the condition and there is no plan
for future dumping of OB.
(iii)
Condition :Trace metals such as Ni,Co,As and Hg should be analyzed in dust fall and
soil samples for at least one year during summer, monsoon and winter season. If
concentrations of these metals are found below the standards then with prior
approval of MOEF this specific monitoring could be discontinued.
Compliance : The trace metals such as Ni, Co, As & Hg are analysed in dust fall and
soil samples for one year during Summer, Post-Monsoon, & Winter season. Analysis
results have already been sent to MoEF, New Delhi vide our office letter
No.NCM/12/789 dated 03.10.2012.
(iv)
Condition :Catch drains and siltation ponds of appropriate size should be constructed
to arrest silt and sediments flows from soil, OB and mineral dumps. The drains should
be regularly de-silted and maintained properly
Garland drains (size, gradient & 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 provided adequate
retention period to allow proper settling of silt material.
Storm water return system should be provided. Storm water should not be allowed to
go to the effluent treatment plant during high rainfall/super cyclone period. A separate
storm water sump for this purpose should be created.

: 2 :
Compliance: The catch water drains (garland drains) and siltation sumps of appropriate
sizes has already been constructed with a length of 350 mtrs to arrest silt and sediment
flow from soil and ore stack yard. Periodical cleaning & proper maintenance of these
drains are being carried out for de-siltation.
To avoid heavy rush of water due to sudden rainfall or maximum discharge of water in
the area adjoining the mines site, the garland drains have been designed to cater at
least 50% more water. Sumps have been constructed so as to allow adequate
retention period for water facilitating, proper settling of silt materials.
(v)
Condition :Dimension of retaining wall at the tow of OB dumps and benches within the
mine to check run-off and siltation should be based on the rainfall data.
Compliance : The OB dump inside the mine has already been utilised for back filling of
old opencast workout quarries. A sump has been constructed at worked out area of
opencast quarry for de-watering after proper settling of silt materials during rainy
season.
(vi)
Condition :Ground water abstraction for domestic use should not exceeds 96.17m3/
day. Balance water requirement (3215 m3/day) of the project should be met only
from the mine pit water.
Compliance : Water for domestic use including losses and other water requirement of
the project is being made from Bore Wells and Underground mine respectively limiting
within the approved limit.
(vii)
Condition :A green belt of adequate width should be raised by planting the native
species around ML area. Plantation should also be carried out along roads. OB dump
sites etc. in consultation with the local DFO/Agriculture Department raising the total
are under afforestation to 24.858 ha. The density of the trees should be around 2500
plants per ha.
Compliance : Plantation on road side, safety zone and reclamation area is being done
in consultation with local D.F.O./Agricultural department and shall be continued in the
reclamation area in future. Efforts shall be made to maintain the density of the trees
around 2500 plants per ha. The following table shows the achievements.
