respectively. As per census, the study area comprises 25.14% population belong to Scheduled

Castes (SC) and 1.97% Scheduled Tribes (ST).

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.

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.

4.2 Greenbelt Development

Greenbelt will be developed along the plant boundary and open spaces.

Greenbelt/landscaping are already being maintained at 25% which covers a land area of 0.81

ha for the existing plant. Additionally 0.27 ha area will be developed. The greenbelt area

after expansion will be 33.12% of total land which has area of 1.08 ha.

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

M/s.GBRMPL proposes to take part in various CSR activities like water supply, Tree

plantation, Bus shelters, medical camp, Road facilities and development of the villages. The

CSR activity plan for the proposed expansion plant is shown in Table-6.1.

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.
