EIA/EMP Report of Beneficiation Plant –BRPL
� Soil Quality
The details of solid waste generated and its management are described
hereunder:
Sn Source Quantity Disposal
1 Raw water treatment plant 72 m 3 /day Shall be used for filling of low lying area
2 Tailings from thickener 0.7 mio tpa Shall be disposed off in tailing dam
3 Sewage Treatment Plant 4-5 kg/day Shall be used as manure for green belt
development/plantation
� Ecology
The impact on the ecology of the study area during operation phase may
account for the following:
• Water availability to the downstream users of the Baitairni river with respect
to withdrawal point at village Kanpur;
• Tailing's spillover from tailing dam during monsoon season; and
• Due to operation of project.
As explained during the impact assessment on water resources on the basis of
last 27 years flow data of Baitairni river at Kanpur village, the water availability
during lean season flow at Kanpur village is uncertain and may affect the
downstream ecology, if continues to withdraw. Hence, impact may be significant
and adverse.
There shall be remote chances of spillover of tailings during monsoon season due
to the following reasons:
• Free board holding capacity of the tailing dam during monsoon shall be
considered on the basis of 250 mm run off which is times higher than the
actual;
• The dam is designed to hold the rain water over the area of the dam only. No
surface run offs shall enter the dam from the catchment area, as retaining
wall/toe walls shall be provided before the embankment of the tailing dam.
No run off entry is envisaged; and
• Sufficient free board taking into the runoff deposition has been taken into
consideration and also near the tailing dam, provision of pumping back the
excess water from the impounded catchments have been considered in
designing the embankment structure of the dam.
During normal operation, ecology shall have positive impact due to the following
reasons:
• Compensatory afforestation shall be carried out; and
• Development of greenbelt/plantation of earmarked land of 28.64% of the
total project area of 89.59 hect.
