A bill to prohibit the use of funds to implement, administer, or enforce certain rules of the Environmental Protection Agency.

This bill prohibits federal funding for implementing, administering, or enforcing specific Environmental Protection Agency (EPA) vehicle emissions rules. It directly affects the EPA's ability to enforce the proposed and final "Multi-Pollutant Emissions Standards for Model Years 2027 and Later Light-Duty and Medium-Duty Vehicles" rules. The key mechanism blocks all fiscal year 2024 funds from being used for these particular rules or any substantially similar future rules. The bill does not alter the rules themselves but prevents their enforcement through funding restrictions.
