Marketing/Service Stations
A time-tested and reliable infrastructure – pipelines, tankers ships, refineries, trains and trucks – works around the clock to bring the fuels you depend on to your corner service station. As that infrastructure has become more efficient and environmentally friendly, so has gasoline retailing. Thanks to some major improvements in pump design, gas formulations, and more leak resistant underground tanks, the fuel dispensed into the car is cleaner—as is the air we breathe as we wait at the pump.

Serving up safety and convenience
In the past, underground storage tanks at gas stations were susceptible to spills or leaks due to overfilling or corrosion, which could then lead to the contamination of surrounding ground water.  Today’s generation of gas storage tanks are composed of fiberglass and corrosion-resistant steel, and armed with leak detection devices and automatic shut-off valves that prevent overfilling.  Regular inspection and maintenance provide additional measures of security.

Tanker trucks now collect the vapors that accumulate inside an underground storage as part of the refilling process. This keeps the vapors from escaping into the air. Similarly, in areas that don’t currently meet National Ambient Air Quality Standards, vapor recovery units built into the pump nozzle siphon vapors back into the underground tank for removal with the next delivery.

All cars manufactured after 2000 have advanced onboard vapor recovery systems, which provide even better vapor protection and increased fuel efficiency. Mounted in the car, these charcoal canisters absorb fueling vapors and pass them to the engine, where they are burned for power when the car is started.
