REIA Report for the Proposed Mini Integrated Steel Plant
Chapter – 2

(E)
AFBC Based Power Plant
The flue gases from the boiler will be treated in a state-of-the-art Electro Static
Precipitator to bring down the particulate emission to less than 50 mg/Nm 3 and
will be let out through a stack of 72 m height for effective dispersion of emissions
into the atmosphere.
Rolling Mill
The flue gases from the Rolling Mill will be let out through a stack of 45 m
height for effective dispersion of emissions into the atmosphere.
Ferro Alloys
The emissions from each of the Submerged Electric Arc Furnaces will be
controlled by providing a fume extraction system with bag filters for each unit
and then let out into the atmosphere through two nos stacks each of 30 m height.
The out let dust emission will be less than 50 mg/Nm 3 .
Whenever Air pollution control systems fail, production in that unit will be
stopped till that air pollution control system is rectified.
2. WATER POLLUTION
Closed circuit cooling system will be provided in the process & cooling of SMS, Rolling
mill and Ferro alloys plants. Hence there will not be any waste water generation from
process and cooling. Boiler blowdown & DM plant regeneration waste water will be
treated in Neutralization tanks and will be mixed with CT blowdown and will be stored
in a Central Monitoring Basin (CMB). The treated effluent from CMB will be partly used
for dust suppression, partly for ash conditioning and the remaining will be utilized for on
land for irrigation. Sanitary waste will be treated in septic tank by soak pit.
3. NOISE POLLUTION
The turbine will be of internationally reputed make and will be manufactured as per
MOEF/OSHA standards on Noise. Acoustic enclosures will be provided to STG. The
major noise levels will be confined to the working zones of the plant. Ear plugs will be
provided to all employees who will enter into the noise prone areas.
