RAINFALL & CLIMATE RAINFALL Normal rainfall of the district is 1640mm of which monsoon rainfall for 4 months from June to September contributes 71.5%. Normal monsoon rainfall is 1173mm and normal nonmonsoon rainfall is 467mm. CLIMATE The district experiences a humid sub-tropical type of climate with minimum and maximum temperature varying from 9 C in the winter to 38 C in summer respectively. Highest temperature recorded in June 1998 was 40 C and lowest temperature recorded in January 2001 was 8 C. Relative humidity varies from 52-88%, its being high in the month of August. d. GEOMORPHOLOGY The district is characterized by gently sloping flat alluvial terrain, which gradually merges to deltaic plain towards south. The elevation of land mass ranges from 10m AMSL in northern part to 3-4m AMSL in the coast, after that the land gradually dips into the Bay of Bengal. In the vicinity of coast falling in Ramnagar and blocks a series of sand dunes stretching ENE- WSW direction of present, which are indicative of palaeo shoreline. Page 6

7 e. SOIL Major part of the district is covered by alluvial soil except a narrow belt along the sea coast in the extreme south where saline soil, saline alkali soil, non saline alkali soil and degraded alkali soils developed. f. INFRASTRUCTURE Since the proposed Project is expansion project within the premises of the Coastal Installation it will use all the infrastructural facilities of the existing Haldia Coastal Installation. INDUSTRIAL WASTE MANAGEMENT Following waste management measures which are in line with the existing practice is conceived in the design to meet the environmental standards and environmental operating conditions for the project: AIR POLLUTION MANAGEMENT The air Pollution mitigative measures conceived for the project is summarized below: Water spraying is conceived to minimize dust Pollution during excavation and earth work (during construction phase). Hydrocarbon is stored in Floating Roof (FR) / Cone Roof to minimize vapour loses. The DG sets have tall stack as specified by CPCB. Greenbelt is also developed along plant boundary to restrict air Pollution. WATER POLLUTION MANAGEMENT Wastewater Management philosophy is based on the following: The wastewater management philosophy is based on Zero Discharge concept. All oily effluents are diverted to Oil Water Separator (OWS). The wastewater from OWS after removal of oil & after testing is used for green Belt development within the Depot. The collected slop oil is disposed off to third party for off-site recovery or recycling. Domestic Sewage generated at the terminal is treated in septic tank and disposed via soak pit. Separate storm water drainage system is provided at the facility. The non-contaminated rain water is discharged directly to rain water harvesting pit within the facility. However, particularly during the monsoon, any oil-contaminated rain water is led to the OWS for treatment prior to discharge. Page 7

8 NOISE POLLUTION MANAGEMENT The following noise abatement measures are practiced for the Haldia Depot: The equipment, which is the source of noise, has built-in type noise control abatement technology. Greenbelt is already developed around plant boundary and other strategic locations to reduce noise Pollution SOLID WASTE MANAGEMENT Following measure is followed for management of solid waste in Haldia Depot: Tank bottom sludge is generated while cleaning of oil storage tanks. The cleaning of oil storage tanks is done once in five years as per practice of Oil Industry. Total tank bottom sludge along with filters contaminated with oil thus generated is kept in secured, covered impermeable sludge pit located within terminal at a central place earmarked for the purpose prior to disposal via incineration or bio-remediation. The spent or used oil will be stored at a specific location prior to safe disposal through MoEF/ State PCB approved registered recycler. Other hazardous wastes if any like spent batteries, waste oil, empty drums of oil/chemicals, fluorescent tubing etc. is disposed off in accordance with approved safe procedures. C.
