The literacy rate is found to be 71.52%. As per census 2011, records the main workers were
found to be 42.57% of the total population. The marginal workers and non-workers were
constituted to 7.24% and 57.43%.
3.0 ANTICIPATED ENVIRONMENTAL IMPACTS AND MITIGATION MEASURES
3.1 Impacts during Operational Phase
3.1.1 Impact on Soil
The soil quality remains the same as the proposed expansion does not involve a change in
land use pattern. The airborne fugitive dust from the plant is likely to be deposited on the
topsoil in the immediate vicinity of the plant boundary. However, the fugitive emissions are
likely to be controlled to a great extent through pollution control measures like water
sprinkling and the greenbelt development.
3.1.2 Impact on Air Quality
Particulate Matter (PM), Sulphur dioxide (SO2) and Oxides of Nitrogen (NOx) will be the
major pollutants emitting from the proposed expansion. In order to control the emissions of
particulates, the pollution control equipments are proposed. Adequate stack height has been
provided to disperse gaseous emissions over a wider area. The maximum resultant ground
level concentration of PM, SO2 and NOx are given in Table-3.1.

Gaseous Emission Control Measures:
A 360° swing suction hood is provided just above crucible at required height to have effective
suction of gases and fumes. Flue gases from the furnace will be passed through hood into
duct and through duct to spark arrestor. The exiting pollution control equipment of Wet
scrubber will be replaced by bag filters to remove the gaseous emissions from the proposed
furnaces.
3.1.3 Impact on Water Quality & Management
As the manufacturing process will be operated only on the dry process, water is mainly used
at certain stages in the process like machinery cooling, scrubber make up and domestic
needs. The entire water demand for the existing and proposed expansion will be met from
existing bore well located within the industrial premises.
GBRMPL has estimated the one time water requirement for the proposed expansion will be
20 KLD and the daily fresh water requirement will be 12 KLD. The domestic sewage (11 KLD)
generated from the proposed expansion will be treated in the existing sewage treatment
plant having a capacity of 60 KLD. The treated wastewater of 8.0 KLD from the STP will be
further treated in the RO treatment system and directed to plant cooling processes. The
remaining 3.0 KLD from the STP will be reused for greenbelt development.
The wastewater from the cooling processes is treated in the cooling pond followed by cooling
tank and the treated water of 8.0 KLD will be recirculated again for the cooling processes.
The scrubber effluent of 0.7 KLD will be treated in the existing solar evaporation pan. No
wastewater will be discharged outside the plant premise. Hence, there is no impact on the
water regime due to the wastewater generation from the plant operation.
3.1.4 Impact due to Solid Waste Generation
In order to avoid problems associated with solid waste disposal, an effective solid waste
management system will be followed. Hence, the impact due to solid waste generation
during the plant operation is not envisaged. The sources, quantity of the solid waste
generation and waste management measures for existing and after the proposed expansion
are presented in Table-3.2.

DETAILS OF SOLID WASTE GENERATION AND MANAGEMENT
3.1.5 Impact on Noise levels
The major noise generating sources are from cooling tower, Air Compressors, Transformer,
TMT cutting machines, DG sets, loading & unloading operation. The predicted noise level at
the boundary due to various plant activities will be ranging in between 40-52 dB (A). It is
seen from the modelling results that the incremental noise levels are within the CPCB
standards.
Noise Attenuation Measures
The following control measures will be implemented for the proposed expansion project:
All the design/installation precautions as specified by the manufacturers with respect to
noise control will be strictly adhered to;
High noise generating sources will be insulated adequately by providing suitable
enclosures;
All the necessary noise protective equipment will be supplied to workmen operating near
high noise generating sources.
The air compressor, DG sets, transformer will be provided with acoustic enclosure;
Other than the regular maintenance of the various equipment, ear plugs/muffs will be
recommended for the personnel working close to the noise generating units; and
Adequate greenbelt development is also being developed in the plant boundary of the
steel plant.

3.1.6 Impact on Ecology
The incremental concentrations of the air quality modelling shows that the resultant levels of
PM, SO2 and NOx were well within the permissible limits as per National Ambient Air Quality
Standards (2009). The impacts on aquatic ecology due to the proposed expansion activity
would be negligible as the treated water will be properly reused and no waste water is
discharged outside the plant premise. The proposed expansion does not create any
significant impact on aquatic bodies.
3.1.7 Impact on Public Health
The discharge of waste materials (stack emission, wastewater and solid wastes) from
process operations can have some adverse impact on public safety and health in the
surrounding area, if appropriate treatment procedures are not followed. As the plant
pollution control equipments will be designed as per the modern available technology for
controlling the impacts, no adverse impacts on public health in the area are anticipated.
4.0 ENVIRONMENTAL MONITORING PROGRAM
The environmental monitoring program is important in terms of evaluating the performance
of pollution control equipment’s installed in the project. The sampling and analysis of the
environmental attributes will be as per the guidelines of CPCB/TNCPB. The frequency of air,
noise, surface water and ground water sampling and location of sampling will be as per the
directives of Tamil Nadu Pollution Control Board.
4.1 Budgetary Allocation for Environmental Protection
The total cost for the proposed expansion project is about Rs.5 Crores. It is proposed to
invest about Rs.50 Lakhs, i.e. 10% of the total cost on pollution control, treatment, green
belt development, rainwater harvesting, environmental monitoring systems and others. The
break-up of the investment is given in Table-4.1.

5.0 DISASTER MANAGEMENT PLAN
To tackle the consequences of a major emergency inside the project premises or its
immediate vicinity, a Disaster Management Plan has been formulated and this planned
emergency document is called “Disaster Management Plan”. The objective of the Disaster
Management Plan is to make use of the combined resources of the steel melting plant and
the outside services, to achieve the following:
Effect the rescue and medical treatment of casualties;
Safeguard other people;
Minimize damage to property and the environment;
Initially contain and ultimately bring the incident under control;
Identify any dead;
Provide for needs of relatives;
Provide authoritative information to the media;
Secure the safe rehabilitation of affected area; and
Preserve relevant records and equipment for the subsequent inquiry into the cause and
circumstance of the Emergency.
5.1 Occupational Health & Safety Measures
Large projects where multifarious activities are involved during construction, erection,
testing, commissioning, operation and maintenance, the men, materials and machines are
the basic inputs. Along with the benefits, the industrialization generally brings several
problems like occupational health and safety.
The industrial planner therefore has to take steps to minimize the impacts and to ensure
appropriate occupational health and safety in the steel melting plant and rolling mill. The
following measures are proposed:
Conducting awareness programs at regular intervals to the employees
Providing safety kits and prevention kits
Provision of Clinic at the project site to handle emergency situations that may arise.
6.0 CORPORATE SOCIAL RESPONSIBILITY

7.0 PROJECT BENEFITS
The basic requirement of the community needs will be strengthened by extending health
care, educational facilities to the community, providing drinking water to the villages,
building/strengthening of existing roads in the area.
The activity of project expansion will provide employment to persons of different skills and
trades. The total manpower required for the proposed expansion during the operation phase
will be 120 persons which would be mainly sourced from local community in and around
existing plant and few technical persons will be employed from outside area. In addition to
the above, direct employment shall be provided to the contractual labour and indirect
employment opportunities will also arise after expansion of the steel melting plant.
8.0 CONCLUSION
The proposed Expansion of steel melting plant and Rolling mill has certain level of marginal
impacts on the local environment. However, development of this project has certain
beneficial impacts/effects in terms of providing the employment opportunities that the same
will create during the course of its setting up as well as during operational phase of the
project.
Thus, it can be concluded that with the judicious and proper implementation of the pollution
control and mitigation measures, the proposed expansion project will be beneficial to the
society and will help reduce the demand-supply gap of billets and steel products will
contribute to the economic development of the region in particular and country in general.
