3.2 Manufacturing Process 3.2.1 Sponge Iron (DRI)
Refractory lined rotary kilns will be used for reduction of Pellets and sized iron ore lumps in solid
state. A central Burner located at the discharge end will be used for initial heating of the kiln.
Pellets or sized iron ore will be continuously fed into the kiln along with coal which has dual role of
fuel as well as reductant. Dolomite will be added to scavenge the sulphur from the coal.
Temperature of the order of 1050ºC will be maintained in the reduction zone, which is the
appropriate temperature for solid state reduction of iron oxide to metallic iron. This hot material
will be transferred to Heat exchanger. In Heat exchanger the material will be cooled to
160ºC. The cooler discharge material consists of sponge iron lumps, sponge iron fines and
char. Magnetic and non-magnetic material will be separated through magnetic separators and
stored in separate bins. The off-gas at about 1000ºC will be led to a waste heat recovery power
plant after which it will be clean in ESP before letting out to atmosphere through stack.
3.2.2 Ferro Alloy Plant
In Ferro alloy plant Ferro Alloys will be produced by smelting of Manganese ore with coke, coal,
quartz and dolomite. Spark arrestor and bag filter modules will be installed for cleaning of flue gas.
3.2.3 Iron Ore Beneficiation And Pelletisation Plant

4.11 Place of tourism/historical/archaeological importance:
None historically or archaeologically important place is within the study area.
5. Anticipated Environmental Impact and Mitigation Measures
5.1 Air quality:
Construction Phase: The construction and erection of proposed plants and equipment will
generate dust resulting in higher SPM levels in surrounding area. The impact on the air quality
during construction phase will be localized, temporary and reversible in nature.
The dust generation during construction will be suppressed through intensive water spraying.
Proper maintenance of equipment and transport vehicles will reduce generation of gases.
Operation Phase: During operation phase, air quality may deteriorate due to emission of gases
and dust from the various units of the plant like coal washery, sponge iron, blast furnace, steel
melting, Iron ore beneficiation, Iron ore pellet plant, sintering plant, rolling mills, lime and dole
plant, Ferro alloys plant and captive power plant. There will be 33 stacks in the plant.
The results of the modeling study indicated that the maximum increase of GLC for the expansion
is 0.96677µg/m3 with respect to the SPM, 2.20271µg/m3 with respect to the SO2 and
1.88723µg/m3 with respect to NOx which is minimal. The GLC predicted at all receptor locations
after the proposed expansion are well within the SPM, SO2 and NOx limit prescribed in NAAQS by
MoEF.
During operation the following facilities will be provided to control air pollution:

Apart from above measures, Leakage from the equipment, ducts and transfer points shall be
regularly checked and stopped. Green belt will be developed to check air pollution in the area.
5.2 Land Environment:
The impact on land environment within core zone will be marginal since most part of the land on
which the plant will be set up is government waste land which has been already leased out to the
company.
The project area under the Integrated Steel Plant will spread over an area of 300 ha of land.
During construction phase, parts of the project area will be converted into internal roads, water
reservoir, buildings, green belt and plantation, etc. The top soil generated during construction will
be preserved and spread over the area identified for development of green belt and afforestation.
5.2.1 Topography and drainage:
No major change in topography shall occur on account of construction of the proposed plant,
except for minor leveling and slight rise in plinth area. Raw material will temporarily increase
elevation in storage area. The natural drainage will be obstructed due to the buildings but that
shall be taken care by the provision of storm water drains.
5.2.2 Soil Quality:
In order that soil quality shall not be adversely affected, suitable preventive measures shall be
taken while designing and constructing the solid waste and liquid effluent disposal systems like;
solid waste dump yard, ash pond and various ETPs.

scrub forests in the buffer zone of 10km radius. These forests have species of flora and fauna
which are commonly found. There are no wildlife sanctuaries or fragile ecosystems within the
study area. The activities of the plant barring transportation shall be restricted within the boundary
wall of the plot. Hence, significant impact on wildlife or fragile ecosystem is not envisaged.
5.6.1 Mitigation Measures:
In order to promote the ecosystem and prevent pollution of environment due to fugitive emissions,
the company has planned to develop green belt in an area of 100 ha.
5.7 Socio-economic Condition:
The impact is positive and prosperity will emerge in the area, right from the onset of project work
because at present the area is very backward. It is envisaged that in operation phase after final
completion of the project about 1862 persons will get employment. About 140-300 persons will be
employed during construction phase. There will be good number of employment generation both
direct and indirect as transportation of materials and other services associated with the project will
be carried out through contracts. As majority of unskilled and semi-skilled persons will be from the
surrounding villages, the net in-migration on account of the job opportunities is expected to be low.
The company has envisaged various peripheral development activities like; opening and
maintaining educational institutions, primary health centre, ambulance and other health services
providing drinking water facilities to nearby villages etc. With the commencement of operation,
communication, entertainment and canteen facilities also will improve.
5.8 Control Measures for Occupational Safety and Health:
Numbers of pollution control measures have been inbuilt in various facilities which are likely to
emit dust, gases and noise so that workers working in the factory area are not exposed to polluted
conditions. Drinking water, canteen and medical facilities will be available within the plant.
Awareness program shall also be conducted. Occupational health check-up of all workmen
working in susceptible areas will be done as per rules in Factories Act. Any worker found to
develop symptoms of dust related diseases will be changed over to other jobs in cleaner areas.
