11.6 Baseline Environmental Data

The baseline data was collected in the study area during the months of October – December 2017. The baseline data includes collection of Samples of ground water, surface water and soil, monitoring of ambient air quality, noise levels, ecological status and meteorological parameters.

11.7 Identification and Quantification of Impacts

The impact assessment report has identified various sources of pollution and quantified the pollution due to proposed expansion project. It has also identified the technologies to be adopted for the mitigation and control of the same. The sources of pollution are air emissions from are Induction Furnace, Rolling mill and GG sets; liquid effluents from utilities and domestic usage; solid wastes from process, treatment systems; and noise pollution from utilities, and process equipment.

11.7.1 Impacts on Air quality

The impacts on air quality shall be due to the emissions from Induction Furnace, Rolling mill and GG sets. The incremental concentrations are quantified using ISC-AERMOD

11-3 Team Labs and consultants Padmasree Steels Private Limited Executive Summary

model based on ISCST3 Algorithm. The results indicate marginal increase in ambient air quality concentration. The predicted values for SPM, PM10, PM2.5, and NOx are 1.17, 0.47, 0..22 and 2.08 g/m3 respectively and he maximum values are observed at a distance of 0.4 km from the center of plant site in north direction, and the cumulative values of baseline air quality combined with predicted values are found to be within the prescribed limits of National Ambient Air Quality Standards. The mitigative and control measures of air pollution shall ensure that the impact on air quality is local – within the site area and its surroundings.

11.7.2 Impacts on Water

Water is essentially used for cooling and domestic purposes. The required water is drawn from ground water sources in addition to reuse of treated wastewater. The total water required is in the order of 250 KLD in addition to reuse of treated wastewater in the order of 196 KLD. No impact on water quality is expected due to discharge of effluents as zero liquid discharge is envisaged, which ensures reuse of treated wastewater for cooling towers makeup.

11.7.3 Impacts on Noise quality

The noise levels may increase due to motors, compressors, GG set and other activities. The major source of noise generation is GG sets which emit noise levels of above 90 dB (A) at a reference distance of 1m from the source. The predicted cumulative noise levels (as calculated by the logarithmic model without noise attenuation) ranged between 55 and 75 dB (A) at distances of 70 to 135 m. The increase in noise levels shall have neutral impact, restricted to within site area.

11.7.4 Impacts on Soil

The solid waste generated from the plant is mill scales from CCM, Rolling Mill and slag from Induction Furnace will be reused as raw material in MS ingots production / Sold to cement manufactures/Sinter plant. Slag residues will be sold as byproduct for using road construction/cement industries. If the slag is not technically feasible for the above purposes the same will be disposed of in a secured land fill.

11.7.5 Impacts on Ecology

There are no endangered species of flora and fauna in the impact area. The impact on biological environment is neutral with the effect confined mainly to the site area.

11.8 Environmental Monitoring Programme

It is proposed to monitor Ambient Air Quality (AAQ) for PM10, PM2.5, SO2 and NOX, stack emissions for induction furnace, rolling mill and GG sets, noise levels on quarterly basis. Water, treated wastewater are monitored on daily basis, while Soil analysis is done once in a year.

11.9 Project Benefits

The proposed project will provide employment to 50 people in addition to the existing 150 peoples. The proposed project will also generate indirect employment to the locals during construction phase in the order of 30 people for a period of 6-12 months. The project shall have positive impact on socioeconomic environment due to provision of employment both direct and indirect and proposed CSR activities.

11.10 Environment Management Plan

The management plan is drawn in consultation with project proponents and technical consultants after evaluating various mitigation and control measures to address the impacts identified, predicted and monitored. The impacts during construction stage are temporary and less significant, the management plan for impacts identified during operation stage is described as follows;

11.10.1 Liquid Effluents

The effluents generated from the proposed plant arise from utility blow downs. These blow downs will be collected in a sump in the ETP, where the suspended solids will be separated by sedimentation. Treated water is used for slag cooling/on land irrigation. The domestic effluent will be sent to septic tank followed by soak pit.

11.10.3 Air Pollution

The sources of air pollution from the plant are induction furnace, rolling mill and GG sets. The proposed air pollution control equipment is scrubber. GG sets shall be provided with effective stack height based on the CPCB formula.
