DC Circuit Questions Validity Of Longstanding Council For Environmental Quality Regulations Implementing NEPA

In a departure from past jurisprudence, a recent DC Circuit decision questioned whether the White House Council on Environmental Quality (CEQ) had the legal authority to issue key regulations under the National Environmental Policy Act (NEPA). The decision, which evaluated federal planning related to tourist flights over national parks, interpreted CEQ's NEPA regulations, which prescribe how federal agencies must comply with NEPA and have set the standards for federal agencies' consideration of the environmental impacts of major federal actions for decades. The decision could impact how many agencies conduct and interpret environmental assessments in areas including biotechnology and agriculture.
