A coalition of state and environmental groups notified EPA on Friday that they intend to sue the agency for ignoring petitions to rectify alleged procedural problems with a February repeal of the so-called endangerment finding.
The Environmental Defense Fund, the Natural Resources Defense Council and other green groups joined public health organizations and state and local governments in submitting the notice of intent to sue. Friday’s action starts a 180-day clock for EPA to respond before a lawsuit would be filed in court.
Many of the groups and governments are also suing to halt EPA’s rollback of the endangerment finding — which underpins most climate regulations — and its repeal of greenhouse gas rules for motor vehicles.
The administrative complaint focuses on claims that in repealing the finding, EPA skirted procedural requirements by relying on modeling and analysis that it had never presented to the public for comment.
