Description of environment

Base line data has been collected on ambient air quality, water quality, noise levels, flora and fauna and socio economic details of people within 10 km radius of the plant.

Ambient air quality

Ambient air quality was monitored for PM2.5, PM10, SO2 and NOx at 8 stations including plant site during 18 APRIL 2024. The following are the concentrations of various parameters at the monitoring stations:

Water Quality

Surface Water Quality

2 no. of samples have been collected from Kharun River which is flowing at a distance of 5.5 Kms. & 1 no. from Chokhara Nallah which is flowing at a distance of 3 kms. from the plant. No other samples have been collected as there is no availability of water in the seasonal streams. Surface water samples have been collected and analyzed for various Physico-Chemical parameters. The analysis of samples shows that all the parameters are in accordance with BIS-2296 specifications.

Ground Water Quality

8 No. of ground water samples from open wells / bore wells were collected from the nearby villages to assess ground water quality impacts and analyzed for various Physico-Chemical parameters. The analysis of samples shows that all the parameters are in accordance with BIS: 10500 specifications.

Noise Levels

Noise levels were measured at 8 locations during day time & Night time. The noise levels at the monitoring stations are ranging from 47.06 dBA to 68.77 dBA.

ANTICIPATED ENVIRONMENTAL IMPACTS AND MITIGATION MEASURES

Prediction of impacts on air quality

The likely emissions from the proposed project are PM₁₀, SO₂ & NO_x The predictions of Ground level concentrations have been carried out using Industrial Source Complex (ISC3) model. Meteorological data such as wind direction, wind speed, max. and min. temperatures collected at the site have been used as input data to run the model.

The likely emissions from the proposed expansion project are PM10, SO2& NOx The predictions of Ground level concentrations have been carried out using Industrial Source Complex (ISC-3) model. Meteorological data such as wind direction, wind speed, max. and min. temperatures collected at the site have been used as input data to run the model.

The predicted max. Incremental PM¹⁰ concentrations (24 hourly) due to the emissions from operation of proposed expansion project will be 0.8 μg/m³ at a distance of 600 m from the stack in the down wind direction over the baseline concentrations.

The predicted incremental rise in PM concentration due to the Vehicular emission will be 0.2 μg/m³

The predicted max incremental SO₂ concentrations (24 hourly) due to the emissions from operation of proposed expansion project will be 5.6 μg/m³ at a distance of 600 m from the stack in the down wind direction over the baseline concentrations.

The predicted max incremental NOx concentrations (24 hourly) due to the emissions from operation of proposed expansion project will be 4.7 μg/m³ at a distance of 600 m from the stack in the down wind direction over the baseline concentrations.

The predicted incremental rise in NOx concentration due to the Vehicular emission will be 1.2 μg/m³. The predicted incremental rise in CO concentration due to the Vehicular emission will be 0.6 μg/m³.

NET RESULTANT MAXIMUM CONCENTRATIONS DUE TO PROPOSED PROJECT

Prediction of impacts on Noise quality

The ambient noise levels are within the standards prescribed by MoEF vide notification dated 14-02-2000 under the Noise Pollution (Regulation & Control), Rules 2000 i.e. the noise levels will be less than 75 dBA during day time and less than 70 dBA during night time.

Prediction of impacts on Water Environment

There will be no effluent discharge in the Induction Furnace as closed-circuit cooling system have been adopted. Effluent from Rolling Mill sent to settling tank & recycled through closed circuit cooling system. Sanitary waste water treated in STP.

Prediction of Impacts on Land Environment

Zero effluent discharge will be adopted. All the required air pollution control systems are provided to comply with CPCB / SPCB norms. All solid wastes are disposed / utilized as per CPCB / SPCB norms. 8 acres (3.24 Ha.) of extensive greenbelt developed as per guidelines. Hence, there will not be any adverse impact on land environment due to the proposed expansion project.

Socio - Economic Environment

There will be certain upliftment in Socio Economic status of the people in the area & development of the area due to the proposed expansion project. Due to this the economic conditions, the educational and medical standards of the people living in the study area will certainly move upwards which will result in overall economic development, improvement in general aesthetic environment and increase in business opportunities.

Environmental monitoring programme

Post project monitoring will be conducted as per the guidelines of SPCB and MoEF&CC are tabulated below:

Air Environment

The following are air emission control system use for controlling pollution in our plant

Note:

Apart from the above Fume extraction system with bag filters, dust suppression system, covered conveyers etc. has also been installed. All conveyors are completely covered with G.I. sheets to control fugitive dust.  All bins are totally packed and covered so that there will not be any chance for dust leakage.  All the dust prone points material handling systems are connected with de-dusting system with bag filters.  All discharge points and feed points, wherever the possibility of dust generation is there a de-dusting suction point are provided to collect the dust.

Water Environment

Closed loop cooling water system are adopted in DRI, SMS.

Greenbelt Development

Greenbelt of 8 acres (3.24 Ha.) of extensive greenbelt will be developed (inclusive of existing) in the plant premises. 20 mtr wide greenbelt will be developed all around the plant in and out.
