Information on the above said parameters has been collected to define the socio-economic profile of the study area (10-km radius). E.3 ANTICIPATED ENVIRONMENTAL IMPACTS AND MITIGATION MEASURES The summary of anticipated adverse environmental impacts due to proposed expansion activity and mitigation measures is given below. E.3.1 Summary of impacts on Air Environment: (a) During construction phase & Mitigation measures Main sources of impact during construction phase are due to movement of vehicles & construction equipment at site, foundation works, transportation of construction material etc. Water sprinkling in the vicinity of the construction area will be done to control dust. PUC certified vehicles will be used. Temporary barricades will be provided to reduce spreading of particulates from construction area.

Executive Summary - Technichem Organics Pvt. Ltd. E-8 San Envirotech Pvt. Ltd., Ahmedabad (b) During operation phase & Mitigation measures At present, flue gas emission is from one stack attached with boiler and one stack of Thermic Fluid Heater. Coal/Biofuel is used as a fuel in boiler & TFH. After expansion, one Boiler, one Thermic Fluid Heater, one Hot Air Generator and D. G. Set will be added. Coal/Biofuel will be used as a fuel

and Cyclone & bag filter will be installed as APCM. HSD will be used in stand by D. G. Set. It will not the constant source of emission, hence no need to install APCM. Acoustic enclosure will be provided to D. G. Set.

Most probable pollutants will be SPM, SO2 and NOx. At present, process emission is from the 1 stack of reaction vessel.

Pollutants from process reactor are NH3 & SO2. After expansion, two process vents and two vents of spray dryers will be added. Probable

pollutant will be PM, SO2 NOx & NH3. Prediction of impacts on air environment is quantified using ISCST3 model. Maximum Ground level

concentrations of 24-hr average for PM, SO2, NOx & NH3 from the proposed activity are 2.076 g/m3, 0.614 g/m3, 0.681 g/m3, and 0.681 g/m3 respectively. These GLCs are expected to occur at a distance of 1.41 km from the source in SW direction. The obtained GLCs are well within the 24-hourly ambient air quality standards stipulated by CPCB. However, to mitigate the impact due to the project activity, unit proposed to provide cyclone separator & bag filter to flue gas stacks and water & alkali scrubber to process reactors and inbuilt cyclone & scrubber to spray

dryer for control of particulates E.3.2 Summary of impacts on Water Environment (a) Impacts during construction phase & Mitigation measures: Temporary impacts are likely to occur due to water consumption & sewage generation. It will not be significant as water requirement would be temporary during construction phase. Proper sanitation facilities with adequate disposal system will be provided within the operational plant. (b) Impacts during operation phase & Mitigation measures: Fresh water requirement of the unit will be satisfied from bore well. Total water requirement after expansion will be around 320.5 KLD; out of which, 60.5 KLD fresh water requirement and 260.0 KLD recycle water (RO permeate & Condensate of MEE). Total effluent generation from

Executive Summary - Technichem Organics Pvt. Ltd. E-9 San Envirotech Pvt. Ltd., Ahmedabad project (excluding sewage) will be 282.0 KLD. The main source of the industrial wastewater generation will be from process, scrubber, washing, boiler, cooling & reject of water treatment. Total trade effluent will be segregated in two stream, Highly Acidic-Dilute Sulphuric Acid and rest of process, scrubber, washing and utilities stream. Highly Acidic stream - Dilute Sulphuric Acid will be sold to actual users under Rule-9 of HAZ Rule. Dilute stream (282.0 KLD) will be treated into ETP and then passed through RO. RO permeate will be reused within premises and reject will be sent to MEE followed by spray dryer. Thus, unit proposed to achieve Zero Liquid Discharge (ZLD). In case in future, If CETP will establish in the vicinity of plant, then unit will discharge effluent to CETP after achieving prescribed norms and permission if any. Domestic wastewater generation will be 8.0 KLD, which will be disposed of into soak pit though septic tank. Hence, no significant impact on the water environment is envisaged. E.3.3 Impacts on Noise quality & Mitigation measures (a) Impacts during construction phase & Mitigation measures: During construction phase, major sources of noise are vehicle’s movement & construction activities. High noise producing activities will be restricted to daytime only. Well maintained equipment will be used to prevent noise. Usage of PPEs by workers will be made compulsory. (b) Impacts during operation phase & Mitigation measures: During the operation phase, the noise will generate due to the operation of pumps, compressors, boiler, HAG, other machineries and vehicular movement etc. The impact is found to be insignificant outside the premises. Acoustic enclosure will be provided to noise generating machineries. Unit will provide necessary PPEs like earplugs or earmuffs to all workers working in high noise area. Selection of any new plant equipment will be made with specification of low noise levels.

Executive Summary - Technichem Organics Pvt. Ltd. E-10 San Envirotech Pvt. Ltd., Ahmedabad E.3.4 Summary of Impacts on Land Environment (a) Impacts during construction phase & Mitigation measures: The construction activities like excavation, leveling & vehicular movements will change the landscape, which are expected to be of short duration & insignificant. Preliminary activities like proper storage of construction materials & proper management will be done within the project area. Therefore, impact will be negligible. Unit will provide sanitation facilities for the staff engaged in construction work which will prevent the impacts on land. (b) Impacts during operation phase &Mitigation measures: Hazardous wastes will have significant negative impacts if disposed unsystematically. Unit will provide all required structural facilities like separate hazardous waste storage room with RCC floor, leachate collection system, and concrete floors within premises. Hence, no significant negative impact is envisaged on the land environment. E.3.5 Summary of impact on Socio Economy (a) Impacts during construction phase & Mitigation measures: Around 25-30 workers for the construction work will be required. Local contractors to be employed for construction, so no other issues like social conflict are envisaged. Temporary employment will be generated during construction phase and it will have beneficial impacts on economic environment. (b) Impacts during operation phase & Mitigation measures:

After expansion, t otal manpower will be 125; i.e. existing 50 nos. and proposed 75 nos. which include manpower at all levels. Which result into a positive impact on prevailing socio-economic environment. Project will also have potential of indirect employment due to the increase transportation activities, contractual works as well as opportunity of trade. Thus, overall impacts on socio-economic environment are long term and positive in nature. E.3.6 Summary of impact on Ecology There are no protected areas like National Park/Wildlife Sanctuary within the 10 km radial periphery of the project site so there will not be any significant impact on ecology.
