Incrementalconcentration due to proposed project was estimated to be SPM (0.26 ug/m 3 ), SO 2(12.15 ug/m 3 ) and NOx (6.39 ug/m 3 ). Air emissions from D.G. sets will be dispersed byproviding adequate stack height. Fresh water requirement from surface water source willbe 20 m 3 /day. Water based mud (WBM) and Synthetic based mud will be used.Wastewater generation during drilling operation will be 5 m 3 /day. Effluent will be treatedin effluent treatment plant (ETP) comprising equalization, chemical coagulation,flocculation and clarification by settling and residual unusable mud will be collected inlined pits and solar evaporated. Drill cutting (DC) will be separated from water basedmud (WBM) and washed properly and unusable drilling fluids (DF) will be disposed off inwell designed lined pit with impervious liner for solar drying. Disposal of drill cuttings anddrill mud will be carried out in accordance with the GSR 546 (E) dated 30 th August, 2005.Used oil will be sent to authorized recyclers.HSD (150-300 l/h) will be used as fuel in rig and D.G. sets during drillingperiod. Number of blow out prevention techniques will be part of drilling rig unit. Blowout preventers (BOP) will be installed to control fluid from the formation gushing to thesurface. Safety measures and fire fighting equipments will be provided at drilling site inaccordance with Oil Mines Regulation, 1984.The Committee deliberated upon the issues raised during the Public Hearing /Public Consultation meeting conducted by the Gujarat Pollution Control Board on
