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.

| 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 |
