REIA Report for the Proposed Mini Integrated Steel Plant
Chapter – 4
As per the WHO recommendation, there is no identified risk and damage of hearing due to
the noise levels (Leq = 8 hours) less than 75 dBA. Most of the international damage risk
criteria for hearing loss permit (Leq = 12 hours) upto 87 dBA. Further, WHO
recommendation on community noise annoyance, permits day time out door noise levels
of 55 dBA. Leq and night time outdoor noise level of 45 dBA leq to meet sleep criteria
i.e. Leq (24 hours) = 52.2. dBA and Ldn = 5.5 dBA.
4.3.3. PREDICTION OF IMPACT ON OCCUPATIONAL HEALTH
The damage risk criteria as enforced by OSHA (Occupation Safety and Health
Administration) to reduce hearing loss, stipulates that noise level upto 85 dBA are
acceptable for 8 hour working shift per day. Plant authorities will provide ear plugs to the
employees and will be enforced to be used by the employees.
4.4 PREDICTION OF IMPACTS ON LAND ENVIRONMENT
90 acres of land is in the possession of the management. As there are no endangered
species in the vicinity of the proposed activity, there should not be any concern for the loss
of important germoplasm that needs conservation.
The flue gases from the kilns will pass through Waste Heat Recovery Boiler & then
through ESP to bring down the particulate emission to less than 50 mg/NM 3 and will be
discharged through two nos. of combined stacks (each stack with twin flues) each of 60m
height for effective dispersion of emissions into the atmosphere.
To control the fugitive emissions dust extraction system and dust suppression syste m will
be installed at all the possible dust emanating areas. All required pollution control systems
will be installed in the proposed expansion project. Hence it will not have any impact on
nearby top soil.
There will not be any process waste water & cooling water blowdown from the steel plant
as closed circuit cooling system is proposed in the expansion. The boiler blowdown, DM
plant regeneration water from the power plant will be treated in a neutralization tank and
utilized for onland for irrigation within the premises. Zero effluent discharge will be
maintained after expansion also. Hence there will not be any adverse impact on land
environment due to the proposed expansion project. Solid waste generated from the plant
will be disposed / utilized as per the norms. Hence there will not be any adverse impact on
land environment due to the proposed expansion project.
