The product profile has been finalized based on the market demand and the technology compatibility. The proposed plant will produce steel in the form of billets and rolled products through IF-CCM-RM route. Steel making will be done using induction furnace. The steel formed is molded into billets and rolled products by casting mills and rolling mills. The detailed manufacturing process is presented in chapter 2 of EIA report. 11.4 Utilities The proposed expansion requires additional cooling tower. It is proposed to establish 1 x 65 TR cooling tower. The GG sets required for emergency power during load shut down is estimated at 1250 kVA and accordingly 1 x 1250 kVA GG set is proposed for expansion in addition to existing 1 x 380 kVA, GG set. The list of utilities is presented in Table 11.3.

The required water shall be drawn from ground water sources in addition to reuse of treated wastewater. The total water requirement is in the order of 250 KLD consisting of 194 KLD fresh water and balance 56 KLD is recycled water. The water balance for daily consumption is presented in Table 11.4.

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.
