This section is the core of the bill, amending Section 797(a) of the Energy Policy Act of 2005. It changes the expiration date for the Diesel Emissions Reduction Act (DERA) program from '2024' to '2029'. This effectively reauthorizes the program, which provides grants and rebates for projects that reduce emissions from diesel engines, for an additional five fiscal years. The extension allows the Environmental Protection Agency (EPA) to continue administering the program and for eligible entities to receive funding for emission reduction efforts.
