EIA/EMP Report of Beneficiation Plant –BRPL
• Trucks shall be properly covered with
tarpaulin
• Preventive maintenance of vehicles
• Fugitive Dust • Adequate arrangement for water spray
shall be provided
• Storage yard shall be properly fenced
and bushes shall be planted at the
periphery of yard
• SPM, SO2, NOX &
CO
• Adequate stack height as per CPCB
guidelines shall be provided
Mitigation Measures
In addition to mentioned above, other mitigation measures are as per given
below:
• Level sensor to have a gap of only half-meter in between stacking boom and
top of pile;
• Plant roads & approach roads shall be made of bitumen/ concrete; and
• Effective house keeping shall be carried out.
� Water Quality
During beneficiation process, water shall be discharged via three different ways:
o Along with tailings to tailing dam;
o Along with beneficiated iron ore to pellet plant at Jajpur; and
o As domestic waste water.
It is envisaged that:
• Tailings shall not contain any soluble mineral hence; overflow from dam shall
be recycled back to process @ 2352 m 3 /day (max) and 1892 m 3 /day
(average);
• At pellet plant, water resulting from filtration of slurry shall be used for
process and domestic usage after adequate treatment; and
• Domestic waste water shall be generated @31m 3 /day. Primary and
secondary treatment shall be provided to make treated water fit for irrigation
purposes to be used for green belt development /plantation.
In addition to above, water quality of the study area may get affected due to:
1. Ground water quality due to leaching from tailing dam
The sub soil investigation of the site allocated for tailing pond and on the axis of
the proposed earthen dam indicates that the top soil is of gray colored clay soil
with gravel up to 1.5 m level form top. The permeability of soil is 4.21x10 -4
cm/sec. The next layer consists of boulder mixed gravel up to 6.0m. There after,
disintegrated rock strata is encountered.
