Since 1994, gas stations in areas that did not meet certain air quality standards were required to curb gasoline emissions at the pump with special emissions control systems. Now that many vehicles are equipped to capture these emissions, EPA began on May 10 to phase out the outdated station recovery systems, potentially saving the approximately 31,000 affected gas stations more than $3,000 each year.
