SHELL MEETS STAGE II VAPOR RECOVERY CLEAN AIR ACT REQUIREMENTS IN CONNECTICUT SERVICE STATIONS

 HARTFORD, Conn., Nov. 16 /PRNewswire/ -- Shell service stations in Connecticut have recently completed installation of Stage II Vapor Recovery systems that will enable them to help to "recycle" gasoline vapors that are emitted during the refueling process. Shell completed the installation of these facilities in Connecticut to meet the federal regulations of the Clean Air Act requirements by Nov. 15, 1993 deadline.
 This "recycling" process, which includes Stage I and Stage II Vapor Recovery systems, is designed to capture gasoline vapors that ordinarily escape during the normal refueling process and during gasoline deliveries.
 Stage II vapor recovery occurs when a motorist refuels his car at the service station pump island. As the gas tank is filled, the displaced gasoline vapors are captured by special nozzles and hoses. These vapors are then routed through separate underground piping back to the station's underground tanks, where vapors are stored. The vapors are subsequently displaced into the gasoline delivery trucks (Stage I Vapor Recovery) during the next delivery of fuel to the service station.
 Stage I Vapor Recovery occurs during tank truck deliveries of fuel into the underground storage tanks. Gasoline flows down from the truck into the partially empty underground tanks displacing the vapors which are routed up through separate piping and hoses back into the tank truck rather than being vented into the atmosphere. The truck takes these vapors back to the distribution plant where they are displaced from the truck into other tanks during truck reloading for the next delivery. The vapors are then reprocessed back into liquid gasoline.
 Shell installed Stage II Vapor Recovery systems at the majority of its Connecticut service stations with the remainder to be converted in 1994. Shell is the third largest retailer of gasoline in Connecticut and is one of the nation's leading retailers of gasoline selling its products through approximately 8,700 service stations nationwide.
