CERTIFIED COSTCO GAS ATTENDANTS
The best environmental and safety features of Costco gas stations are our trained fuel attendants. Attendants must pass a certification test before they can work at a Costco gas station. Our attendants work at the fuel islands so they can respond immediately to any safety or environmental issue.CONTINUOUS LEAK MONITORING
All Costco gas stations have corrosion-proof double-wall underground storage tanks and piping. Everything underground is continuously monitored for leaks via an electronic monitoring system. The entire station will automatically shut down if a leak is detected. These electronic alarm systems are monitored around the clock by both our employees and an outside service.VAPOR RECOVERY SYSTEMS
Our gas stations feature vapor recovery systems which capture gasoline vapors displaced during vehicle refueling and routes them back to the underground storage tanks. Various government agencies, led by California's Air Resource Board (CARB), closely control the approval and use of these systems. Costco works closely with CARB and other local agencies to test new pollution control equipment by offering our high-volume stations as certification test sites.Spill Cleanup Program
The best equipment in the world doesn't prevent the occasional surface spill. Spilled fuel is a safety as well as environmental concern, so we train our gas station attendants on how to properly clean up a surface spill. Every Costco station operates with a spill kit on the fuel islands.Safety
Trained and certified Costco attendants stationed on the fuel islands make our gas stations safe places to buy fuel. Our employees help customers in a variety of ways, including aid to anyone requiring physical assistance in fueling their vehicle. They arecharged with enforcing the national fire code, including prohibitions against smoking, leaving the engine running, or filling portable containers not certified for such use.
