Bitar KanikaGahirmathawildlife sanctuary is located at distance of 170 Km east.Adequate stack height will be provided to D.G. sets. Any hydrocarbon generatedduring testing will be diverted to the burner for combustion. Values of PHC wereobserved in the range of 0.25 ug/l to 4.11 ug/l. Total water requirement for domesticpurpose will be 35 m 3 /day. Sewage will be treated in sewage treatment plant.Waterbased drilling fluid will be used in the well. Synthetic oil based drilling mud (SOBM) willbe used in case of specific hole problem. SOBM will not be discharged into sea.Drillcutting will be segregated from the drilling mud. Drilling mud will be recycled. Drillcuttings will be washed and disposed into sea. If drill cutting found toxic, these will bebrought to shore for safe disposal. Power requirement will be met from DG sets.
