This joint resolution would disapprove an Environmental Protection Agency (EPA) rule titled "Air Plan Approval; Montana; Regional Haze Plan for the Second Implementation Period" (90 Fed. Reg. 54586, November 28, 2025). The resolution says that, if passed by Congress and enacted, the rule "shall have no force or effect." The resolution was introduced in the Senate by Senator Sheldon Whitehouse on March 9, 2026, and was read twice and referred to the Committee on Environment and Public Works.
If this joint resolution becomes law, the specific EPA rule approving Montana's second regional haze implementation plan would be nullified and would no longer be in effect. No publicly available information on other direct effects or next steps is provided in the bill text or metadata.
No publicly available information on costs or budgetary effects appears in the bill text or metadata.
