A joint resolution providing for congressional disapproval under chapter 8 of title 5, United States Code, of the rule submitted by the Environmental Protection Agency entitled "Finding That Lead Emissions From Aircraft Engines That Operate on Leaded Fuel Cause or Contribute to Air Pollution That May Reasonably Be Anticipated To Endanger Public Health and Welfare".

This joint resolution (SJRES 52) seeks to block an Environmental Protection Agency (EPA) rule that determined lead emissions from aircraft using leaded fuel endanger public health and welfare. If approved, it would nullify the EPA's October 2023 rule (88 Fed. Reg. 72372), preventing it from taking effect. The rule directly affects aircraft operators and manufacturers using leaded aviation fuel, as it would have required addressing lead emissions under the Clean Air Act. The resolution, introduced by Senators Murkowski and Sullivan, uses a statutory process to halt the EPA's finding without creating new regulations.
