The Future of Environmental Review of Federal Permitting Remains Unsteady as White House Seeks to Rescind NEPA Regulations
On February 19, 2025, the Council on Environmental Quality (CEQ) submitted a proposed Interim Final Rule rescinding its regulations implementing the National Environmental Policy Act (NEPA). The Rule will become effective 45 days after its publication in the Federal Register, marking the end of nearly 50 years of CEQ regulations serving as the foundation for federal environmental reviews. This Interim Rule comes right at the deadline set by President Trump’s Executive Order (EO) 14154—Unleashing American Energy—which rescinded CEQ’s authority to issue NEPA regulations and revoked President Carter’s EO 11991, which had originally directed CEQ to promulgate implementing regulations.

President Trump’s Executive Order Seeks to Reduce Federal Regulation
President Trump’s January 31, 2025, Executive Order (EO) titled “Unleashing Prosperity Through Deregulation,” is a part of the new Administration’s broader policy to reduce federal regulation. The EO finds that federal regulations impose significant costs and complexities on American citizens and businesses that hinder economic growth, innovation, and global competitiveness – and it is the Administration’s policy to alleviate these burdens. This marks a policy change from the approach of the prior administration and is a broader effort than the regulatory reforms of the first Trump Administration.
