About the EPAct Transportation Regulatory Activities

The Energy Policy Act (EPAct) of 1992—as amended by other key federal statutes—directed the U.S. Department of Energy to develop the Alternative Fuel Transportation Program to manage the following EPAct transportation regulatory activities, which aim to reduce U.S. petroleum consumption through the use of alternative fuels, alternative fuel vehicles (AFVs), and other petroleum-displacement methods.

State and Alternative Fuel Provider Fleets

The State and Alternative Fuel Provider Fleet Program requires covered fleets either to acquire alternative fuel vehicles as a percentage of their annual light-duty vehicle acquisitions or to employ other petroleum-reduction methods in lieu of acquiring AFVs. DOE established these requirements through 10 CFR Part 490, available from the U.S. Government Printing Office.

Learn more about compliance methods.

Alternative Fuels Authorization

EPAct authorizes DOE to add fuels to the list of EPAct-defined alternative fuels by making a final rule after a petition process. Petitioners must demonstrate fuel composition, environmental, and energy security benefits before DOE will undertake a rulemaking. The regulatory process for alternative fuel petitions is extensive and resource-intensive, involving full public disclosure. Documents and media submitted during this process are published in an online docket.

Private and Local Government Fleet Determination

EPAct 1992 required DOE to determine whether private and local government fleets should be subject to DOE's Alternative Fuel Transportation Program and associated requirements. Unlike the mandates for other regulated fleets, Congress conditioned DOE's authority to implement a private and local government fleet regulation on whether such a regulation was necessary to achieve the Replacement Fuel Goal.

In March 2008, DOE determined not to require private and local government fleets to acquire AFVs because such a requirement is not necessary to achieve the Replacement Fuel Goal. Learn more about DOE's Private and Local Government Fleet Determination.

Replacement Fuel Goal Modification

The Replacement Fuel Goal is a goal established by statute to replace 30% of U.S. motor fuel use with non-petroleum fuels by 2010. EPAct 1992 directed DOE to evaluate this goal periodically and modify it if DOE found it not practical and achievable. In March 2007, DOE modified the Replacement Fuel Goal, extending it to 2030.
