E.3 ANTICIPATED ENVIRONMENTAL IMPACTS AND MITIGATION MEASURES Impact identification has been carried out for various activities involved in construction as well as operational phase of the project and prediction has been done for significant impacts. The summary of anticipated adverse environmental impacts due to proposed project 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. (b) During operation phase & Mitigation measures Flue gas emission will be from one stack attached with boiler, one common stack of three nos. of Hot Air Generators (2 nos. of 20 lakhs kcal/hr. and one will of 7.5 lakhs kcal/hr.) and one stack of stand by D G Set. Coal will be used as a fuel in boiler & HAGs and HSD in stand by D G
Set. Most probable pollutants will be SPM, SO2 and NOx. Process emission will be from the spray dryers and pollutant will be PM.
Executive Summary – Sharp Chemicals E-6 San Envirotech Pvt. Ltd., Ahmedabad Prediction of impacts on air environment is quantified using ISCST3 model. Maximum Ground level concentrations of 24-hr average for PM, 3 3 SO2, NOx from the proposed activity are 2.866 g/m , 0.668 g/m and 0.653, respectively. These GLCs are expected to occur at a distance of 1.41 km from the source in NE 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 proposed, unit will provide Cyclone & bag filter to flue gas stacks and cyclone + water scrubber to process stacks, adequate stack height for proper atmospheric dispersion as per the norms. 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 water supply. Total water requirement (Industrial + Domestic + Greenbelt) will be 165.5 KLD; out of which 61.5 KLD will be fresh water requirement & 104.0 KLD will be recycle/treated water (Process-RO permeate & ETP-RO permeate). Total w/w generation will be 78.0 KLD. Sources of industrial effluent generation will be process, washing, water treatment and utilities. Total effluent will be taken into ETP and then passed through RO. RO permeate will be reused within premises and reject will be spray dried. Sewage (2.8 KLD) will be disposed to soak pit followed by septic tank. Thus, achieving Zero Liquid Discharge (ZLD). Hence, no 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 equipments will be used to prevent noise. Usage of PPE by workers will be made compulsory.
Executive Summary – Sharp Chemicals E-7 San Envirotech Pvt. Ltd., Ahmedabad (b) Impacts during operation phase & Mitigation measures: During the operation phase, the noise levels may increase due to the operation of boiler, HAG, D.G. set, process plant, vehicular transportation & other machineries. The impact is found to be insignificant outside the premises. Unit will provide necessary PPEs like earplugs or earmuffs to all workers where exposure is 85 dB(A) or more. Selection of any new plant equipment will be made with specification of low noise levels. 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: As it is a Greenfield project, 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 generated during construction of project will have beneficial impacts on economic environment. (b) Impacts during operation phase & Mitigation measures: Project will require about 35 persons for its operation, 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
