Compliance Methods for State and Alternative Fuel Provider Fleets

State and alternative fuel provider covered fleets may meet their Energy Policy Act (EPAct) requirements through one of two compliance methods: Standard Compliance or Alternative Compliance.

Standard Compliance

Standard Compliance requires covered fleets to acquire a certain percentage of alternative fuel vehicles (AFVs) each year based on the number of light-duty vehicles they acquire.

Alternative Compliance

Alternative Compliance allows covered fleets to obtain a waiver from the AFV-acquisition requirements of Standard Compliance and instead implement petroleum-reduction measures.

Petroleum Reduction
Hybrid Electric Vehicles (or other energy-efficient conventional fuel technologies) No credit Petroleum reduction from hybrids or other fuel-efficient conventional vehicle technologies counts toward petroleum reduction in model year in which efficiencies occur
Light-Duty AFVs 1 credit per AFV Credit for alternative fuel use on gasoline gallon equivalent (GGE) basis
Medium- and Heavy-Duty AFVs Credit only after requirement is met with light-duty vehicle acquisitions Credit for alternative fuel use on a GGE basis
Biodiesel Blends 1 credit for every 450 gallons of pure biodiesel (B100) in blends of B20 or higher used in medium- and heavy-duty on-road vehicles; capped at 50% of annual requirement; only to extent blend percentage exceeds the amount already prescribed by state or federal law Credit for biodiesel used in vehicles in any blend percentage on a GGE basis; no cap on amount of biodiesel used to meet requirements
Vehicle Miles Traveled (VMT) Reduction No credit Credit for petroleum reduction in the model year VMTs are reduced
Idle Reduction No credit Credit toward petroleum reduction
Truck Stop Electrification No credit For covered fleet only; no credit for third-party use
