What it does
This is a Congressional Review Act resolution that disapproves an EPA rule approving South Dakota's air-quality plan for reducing regional haze pollution. If passed, the rule is nullified and has no legal effect, blocking the EPA's approval of South Dakota's compliance strategy for the second implementation period of the Regional Haze Rule.
Why we flagged it
This is a straightforward Congressional Review Act disapproval resolution targeting a specific EPA air-quality rule. It uses the CRA's one-sentence procedural mechanism to nullify an environmental protection without substantive legislative debate.
What the text implies
- Disapproving the rule does not prevent the EPA from resubmitting a similar rule; however, under CRA rules (5 U.S.C. 801(b)(2)), the agency cannot issue a substantially similar rule without new congressional authorization, effectively blocking regional haze enforcement in South Dakota for the second implementation period.
- South Dakota's failure to meet Regional Haze visibility targets may trigger federal implementation of a stricter plan, shifting regulatory authority from the state to EPA — the opposite of the bill's apparent intent.
- Downwind states (including those in the Northeast and Upper Midwest) that depend on South Dakota's emissions reductions to meet their own visibility targets may face enforcement pressure or be forced to adopt more stringent local controls.
Section numbers refer to the bill text the analysis read — linked under Primary records below.
Who it affects
Disapproving the EPA's regional haze rule removes a federal air-quality protection that was designed to reduce visibility-impairing pollution across multiple states. Citizens in South Dakota and downwind states lose the air-quality improvements and visibility restoration that the approved plan was intended to deliver.
Who stands to gain
- coal-fired power plants and other industrial emitters in South Dakota
- energy producers subject to regional haze compliance costs
