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 relating to "Review of Final Rule Reclassification of Major Sources as Area Sources Under Section 112 of the Clean Air Act".

# Summary of SJRES 31 **What the Bill Does:** This bill cancels an EPA rule that was issued in September 2024 regarding how certain air pollution sources are classified under the Clean Air Act. Specifically, the rule required industrial facilities that emit persistent and bioaccumulative hazardous air pollutants (chemicals that accumulate in the environment and in living organisms) to continue following strict emission standards even if they downgrade their classification from "major sources" to "area sources." By passing this resolution, Congress rejected that EPA rule and prevented it from taking effect. **Who It Affects:** The bill primarily affects industrial facilities and manufacturers that emit hazardous air pollutants. It also impacts environmental protection efforts and air quality standards.

The rule being canceled would have applied to sources of toxic air pollutants like mercury and other persistent chemicals. **Current Status:** The bill has been signed into law, meaning it has been approved by Congress and the President. This is one of several recent congressional efforts to overturn or disapprove of EPA regulations through a legislative process that allows Congress to nullify agency rules.
