Gas & Automotive

Costco Gas Station maintenance and equipment are designed to limit emissions arising from station operations, and to contain gasoline vapor during the bulk deliveries and the refueling process. Specific examples include:

• The nozzles have been upgraded to create less spills and drips, resulting in less evaporation to air pollution, and a cleaner gas purchase.
• Costco is the first retailer to place tank pressure management systems in California to greatly reduce the emissions generated from the storage tanks during routine business. Similar systems are installed at other Costco Gas Stations all around the country.

In addition, our stations have corrosion-proof, double-wall underground storage tanks, piping and containment sumps that are continuously monitored for leaks. Finally, our station attendants and management staff are trained and certified on safety and environmental issues.
