Title 42 › Chapter CHAPTER 134— - ENERGY POLICY › Subchapter SUBCHAPTER I— - ALTERNATIVE FUELS—GENERAL › § 13220
The Secretary must give one credit to a fleet or covered person for each qualifying amount of fuel that has at least 20 percent biodiesel and is bought after this rule began, when that fuel is used in vehicles the fleet owns or runs that weigh more than 8,500 pounds. No credit is given for biodiesel bought for use in alternative-fuel vehicles or if the purchase was required by federal or state law. The Secretary can lower the 20 percent rule for cold starts, safety, or vehicle performance. The fleet must provide written proof to get a credit. If the fleet asks, the Secretary will count each credit as if the fleet bought one required alternative-fuel vehicle for that year. Credits may only meet up to 50 percent of a fleet’s required alternative-fuel vehicle purchases, except for certain biodiesel providers. A credit under this rule is not the same as a credit under section 13258. “Biodiesel” means a diesel fuel substitute made from nonpetroleum renewable sources that meets EPA registration under section 7545 and includes fuel made from animal wastes, municipal solid waste, sludges, and wastewater oils. A “qualifying volume” is 450 gallons, unless the Secretary sets a higher amount by rule after finding that the average annual alternative-fuel use in light-duty vehicles is more than 450 gallons. The Secretary must issue implementation rules before January 1, 1999, and collect the data needed to set the qualifying volume.
