Portland is the first city in the country to establish a local renewable fuel standard (RFS), reports Portland Online
The new standard, which will take effect on July 1, 2007, requires a minimum 5 percent blend of biodiesel for all diesel fuel sold within city limits. Gasoline is required to contain at least 10 percent ethanol.
The ordinance has financial penalties for non-compliance, though an exemption is made if a service station provides at least one pump containing a 20 percent biodiesel blend.
The new RFS ordinance also requires that City-owned vehicles that operate on diesel use biodiesel blends of not less than 20 percent and City-owned flex-fuel vehicles must use E-85 fuels.
