EXECUTIVE SUMMARY FOR ENVIRONMENTAL CLEARANCE FOR PROPOSED STORAGE CAPACITY EXPANSION OF BPCL DURGAPUR LPG BOTTLING PLANT AT RAJBANDH CHOTI, BURDWAN, WEST BENGAL EXECUTIVE SUMMARY I. PROJECT DESCRIPTION Bharat Petroleum Corporation Limited (BPCL) is a fortune 500 oil refining, exploration and marketing PSU with Navratna status. BPCL has multiple refinery units in Mumbai, Kochi & Numaligarh. The latest addition is Bina Refinery Bharat Oman Refinery Limited (BORL) which is promoted by a Bharat Petroleum Corporation Limited (BPCL) and Oman Oil Company Limited (OOCL) has set up refinery with capacity & it is a 6 MMTPA grass root refinery at Bina, Madhya Pradesh, along with crude supply system consisting of a Single Point Mooring system (SPM), Crude Oil Storage Terminal (COT) at Vadinar, District – Jamnagar, Gujrat and 935 Km long cross country crude pipeline from Vadinar to Bina. BPCL has also many LPG Plants, POL Depots, Installations & TOPs spread across the country for further distribution of petroleum products to consumers. BPCL now proposes to increase storage capacity of the existing LPG Bottling Plants located at Rajbandh Choti, in the state of West Bengal.for meeting the increasing demand of L.P.G. cylinders in the neighboring areas. With the above in view, BPCL proposes to install two mounded bullets and add 2 nos of bays in the TLD gantry in the existing LPG Bottling Plants located at Rajbandh Choti, in the state of West Bengal. BPCL proposes for installation of mounded bullet keeping the safety aspect in mind. Cylindrical pressures vessels installed on compact sand bed and covered with sand mound in a pyramid shape. The mounded storage of LPG has proved to be safer compared to above ground storage vessels since it provides intrinsically passive and safe environment and eliminates the possibility of Boiling Liquid Expanding Vapour Explosion (BLEVE). The cover of the mound protects the vessel from fire engulfment, radiation from a fire in close proximity and acts of sabotage or vandalism.

E-6 EXECUTIVE SUMMARY FOR ENVIRONMENTAL CLEARANCE FOR PROPOSED STORAGE CAPACITY EXPANSION OF BPCL DURGAPUR LPG BOTTLING PLANT AT RAJBANDH CHOTI, BURDWAN, WEST BENGAL Fire detection and Protection System The fire protection and detection system are in accordance with OISD 144. The existing fire water net work will be extended to form a loop around tank farm. The proposed bullets and LPG pumps will be provided with Medium Velocity water spray system automatically actuated and fed through Deluge Valve. - All LPG vessels are equipped with safety device such as safety relief valve (SRV)< High level Alarms (HLA) and Remote Operated Valves (ROV) for safe operations - Emergency trip button is provided at filling / Filled shed and LPG pump house for shutting down all LPG operations in case of any emergency. - The Plant has CCTV cameras installed in critical locations in the plant. - Safety messaging system : It is an automatic announcement system for safe messages over speaker in front of the security cabin. - Auto fire detection by Quarzoid Bulbs: The quarzoid bulbs are installed in the LPG handling sheds in the airline connected to deluge valve. The line is pressurizes with air at 3.5 kg/cm2. The line is designed show that airflow through a single quarzoid bulb will make the system unhealthy and the same is identified by the fire fighting panel. Whenever the fire occurs in any of the LPG handling sheds and the temperature rises to 79 deg. C, the quarzoid bulb will melt and and the entire air off the line & deluge valve will discharge through it. As a result, the pressure in the line goes low and same will be sensed by pressure switch and sends the signal to the fire fighting panel. Then the fire fighting panel activities Deluge valve, trips LPG equipment and operation siren.
