Washington, D.C. – Gas stations in the U.S. may be able to ditch their gas pumps’ fuel vapour recovery system under a new proposal by the Environmental Protection Agency (EPA).

The Clean Air Act proposal would waive the requirement for stations to have the systems by 2013, since it is estimated that 70 per cent of all vehicles will be equipped by then with on-board systems to capture the vapours. The EPA said that the measure would continue to protect air quality and public health while potentially saving affected gas stations more than US$3,000 annually.

Since 1994, gas stations in certain areas have been required to use the systems, which capture fumes that escape from gasoline tanks during refuelling. However, as required by the Clean Air Act, automakers began installing onboard refuelling vapour recovery (ORVR) technologies in 1998, making the systems at the pump redundant. Since 2006, all new automobiles and light trucks are equipped with ORVR.
