The Environmental Protection Agency signaled plans to accelerate deregulation after recent Supreme Court decisions limited agency discretion, targeting additional rollback of climate and pollution rules.
EPA Administrator Lee Zeldin said the agency would pursue rule changes consistent with the major questions doctrine and narrower interpretations of statutory authority. Priority areas include power plant emissions standards, vehicle tailpipe rules, and wetlands protections.
Environmental groups pledged legal challenges, arguing the rollbacks endanger public health. Industry supporters said clearer, less burdensome rules will lower compliance costs and encourage domestic manufacturing investment.
The Supreme Court in recent terms has curbed agency deference, forcing regulators to rely more explicitly on congressional text. EPA staff have been directed to review hundreds of existing regulations for potential revision or rescission.
Rollback targets include the Biden-era power plant rule and wastewater standards for coal facilities. EPA said revised analyses will justify weaker limits under the Clean Air Act. Environmental Defense Fund and Sierra Club pledged litigation within days of final rule publication. States including California may adopt stricter own standards, creating a split regulatory environment for automakers and utilities.
Coal-state lawmakers praised EPA rollbacks while coastal states promised litigation. Power companies requested clearer timelines for compliance investments. The agency also delayed methane monitoring requirements for some production sites pending revised economic impact analyses.
