What this bill would do
This bill, titled the "Stop California from Advancing Regulatory Burden Act of 2025," seeks to amend the Clean Air Act. It aims to eliminate a specific waiver under the Act and remove the authorization for States to use new motor vehicle emission and engine standards that are identical to those in California. Additionally, the bill prohibits States or political subdivisions from enforcing standards related to emissions from certain nonroad engines or vehicles, such as construction, farm, or locomotive equipment. It also mandates that any existing or pending waivers under the specified section of the Clean Air Act lose their force or be considered denied upon enactment.

Who it would affect, and how
Potential Positive Impacts for People
- Prohibition on State Standards for Nonroad Equipment: By preventing States or political subdivisions from adopting or enforcing requirements related to emissions from certain nonroad engines or vehicles, this could impact those using construction equipment, farm equipment, or locomotives (Section 2, subsection a).
Potential Negative Impacts for People
-
Loss of Existing Waivers: The bill states that any waiver issued before the date of enactment will no longer have any force or effect, which could impact current regulatory processes (Section 2, subsection b, clause 1).
-
Denial of Pending Applications: Any application for a waiver currently pending before the Administrator of the EPA will be considered denied upon the enactment of this Act (Section 2, subsection b, clause 2).
-
Elimination of State Authorization for Motor Vehicle Standards: The bill repeals the authorization for States to use motor vehicle emission and engine standards identical to those adopted in California (Section 3, subsection a).
