PFCs, also known as gas cans, are used to fill a variety of equipment including lawnmowers, vehicles and personal watercraft. The mission of this program is to ensure that spillage and evaporative emissions are minimized or eliminated through the implementation of low permeation plastics and automatic sealing nozzles. Because of their large numbers, PFCs have the potential to create substantial hydrocarbon emissions resulting in ozone-forming smog and health related problems. As of July 1, 2007, all PFCs sold in California must be certified by the California Air Resources Board as meeting the low-emission requirements.
