On Jan. 9, 2020, the Trump administration’s Council on Environmental Quality (CEQ) proposed rules that would update comprehensively the regulations promulgated under the National Environmental Policy Act (NEPA) for the first time in 40 years. After 40 years there is little question that the regulations could use updating and that environmental reviews can be streamlined. However, these proposed revisions go beyond seeking efficiencies and better coordination. Rather, they seek to narrow federal agencies’ NEPA obligations with a goal of expediting projects and reducing the number of actions subject to NEPA review. Whether one considers NEPA an important tool for factoring environmental considerations into decision-making, or an unnecessary and bureaucratic roadblock for critical projects, the proposed changes, if adopted in their present form, raise significant questions that will likely lead to litigation, and could add uncertainty and delay to the federal environmental review process, the opposite of the stated goal of the measures.
