Chemical synthesis consists of four process steps - reaction, separation, purification, and drying. Large volumes of solvents are used during chemical syntheses as medium, extractions, and solvent interchanges. The manufacturing process of all the compounds, reactions involved, material balance are presented at separate annexure of EIA report. Utilities The proposed expansion requires additional steam for both process and effluent treatment system. It is proposed to establish coal fired boiler of capacity 1 x 10 TPH to meet the steam requirement for process, in addition to existing 1 x 5 TPH coal fired boiler, 1 x 2 Lakh K. Cal/hr oil fired thermic fluid heater. Existing 1 x 5 TPH coal fired boiler will be kept as standby after expansion. The total power requirement is estimated to be 1500 kVA. The DG sets required for emergency power during load shut down is estimated at 1500 kVA and accordingly 2 x 500 kVA proposed in addition to existing 2 x 250 kVA and 1 x 180 kVA. Existing 1 x 180 kVA DG set will be dismantled after expansion.

The total water requirement after expansion increased from 71.47 KLD to 434 KLD. The fresh water consumption is optimized by reusing treated wastewater to an extent of 170 KLD, thus reducing fresh water consumption to 264 KLD during operation. The fresh water shall be drawn from ground water in addition to reuse of treated wastewater.

Baseline Environmental Data The baseline data was collected in the study area during March -May 2019. 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. The analytical results show that the values are within the prescribed limits for air quality. The ground water quality is observed to be above the limits for potable purpose when compared to the prescribed standards of IS: 10500 – 2012 at few locations. E-4 Team Labs and consultants Executive Summary Identification and Quantification of Impacts The impact assessment report has identified various sources of pollution and quantified the pollution loads due to proposed project. The sources of pollution are air emissions from utilities and process; liquid effluents from process, utilities and domestic usage; solid wastes from process, treatment systems and utilities; and noise pollution from utilities, and process equipment. A detailed impact assessment was made using rapid impact assessment matrix method. The salient features are presented as follows. Impacts on Air quality: The impacts on air quality shall be due to the emissions from, coal fired boilers, and standby DG sets. The incremental concentrations are quantified using ISC-AERMOD model based on ISCST3 Algorithm for proposed utilities of Porus Laboratories Pvt. Ltd. Unit I. The results indicate marginal increase in ambient air quality concentration. The predicted values for SPM, PM10, PM2.5, SO2 and NOx are 1.86, 0.75, 0.34, 2.17 and 2.79 g/m3 respectively and the maximum values are observed at a distance of 0.8 km 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.
