In plain English: what this bill does

The bill would extend a federal diesel emissions reduction program for five more years. It does this by changing one date in the Energy Policy Act of 2005: the program's authorization now runs through 2029 instead of 2024. The bill makes no other changes.

Who this affects

  • Diesel engine owners and operators: the bill does not state a direct change for them, but it keeps in place a federal program that helps reduce diesel emissions, which this bill extends through 2029.

Words to know

  • Reauthorize: to approve a program again so it can keep running for a set period.
  • Authorization: the legal permission a law gives for a program to operate and receive funding.
  • Emissions: gases or particles released into the air when fuel is burned, such as from a truck or bus engine.

For example

Made-up situation: A city transit agency is part of the diesel emissions reduction program. Under this bill, the program would still be authorized in 2025 through 2029, so the agency could keep taking part instead of losing access when the old 2024 date passed.
