Every day, gas station activities generate five tons of gasoline vapors that contain toxic compounds, which can be harmful to our health. The vapors can escape during refueling of automobiles and refilling of gasoline storage tanks. That’s why we partner with the owners and operators of the 1,200 + gas stations in King, Kitsap, Pierce and Snohomish counties to ensure they can run their business smoothly, and safely.

Gasoline vapors contain compounds called air toxics that can sting eyes, aggravate respiratory problems, such as asthma and emphysema, and cause cancer if inhaled over a long period.  They are also major contributors to the formation of ozone (smog), which is strictly regulated by the Environmental Protection Agency who is planning a stricter standard soon.

Submit test activity reports

(For testers only)

As of September 1, 2011, new regulations for gas stations will more effectively keep gasoline vapors out of the air and more gasoline in station storage tanks – protecting air quality and saving money. 

The new regulations will:

  • Simplify requirements for gas station owners and operators,
  • Increase compliance testing,
  • Require technicians to be certified to do testing, installations, and repairs.

See the links below to learn the roles of our partners who are helping to protect the health of gas station employees, customers, and the environment from the potentially harmful effects of gasoline emissions.
