Following the Council on Environmental Quality’s (CEQ) July 2020 overhaul of regulations implementing the National Environmental Policy Act (NEPA), environmental plaintiffs filed a series of lawsuits challenging the rule in federal courts in California, Virginia, New York, and the District of Columbia. The plaintiffs argued that CEQ violated NEPA itself in promulgating the final rule by failing to prepare an environmental assessment (EA) or environmental impact statement (EIS). They also argued that CEQ ran afoul of the Administrative Procedure Act (APA) by failing to follow notice-and-comment requirements, by issuing a final rule that is “arbitrary and capricious,” and by improperly narrowing both the scope of projects under review and the types of impacts agencies should consider.
