This analysis was written for v1 (INTRODUCED IN SENATE, Jul 10, 2025). REPORTED TO SENATE changed too little to need its own, so it reuses that one rather than a rewrite. The differences between the two are summarized above. View v1

Bottom line

The bill reauthorizes the federal Diesel Emissions Reduction Act (DERA) program until 2029, allowing it to continue funding projects aimed at reducing pollution from older diesel engines.

What it actually does

This bill amends the Energy Policy Act of 2005 by extending the authorization for the diesel emissions reduction program (DERA) from its current expiration date of 2024 to 2029. This action ensures that the program, which provides grants and rebates for projects that reduce diesel emissions, can continue to operate and receive federal funding for an additional five years.

Section 2

Reauthorization of Diesel Emissions Reduction Act

prominently featuredstraightforward

This section is the core of the bill, directly amending Section 797(a) of the Energy Policy Act of 2005. It specifically strikes the year "2024" and inserts "2029," thereby extending the authorization for the Diesel Emissions Reduction Act (DERA) program. This legislative change ensures that the program, which supports projects to reduce emissions from existing diesel engines, remains active and eligible for federal appropriations for an additional five years beyond its previous sunset date.
