National Environmental Policy Act Regulations
What happened
Donald Trump signed this final rule on September 1, 2026, which finalizes an interim final rule from July 3, 2025. It revises the National Environmental Policy Act (NEPA) implementing regulations for the Federal Highway Administration, Federal Railroad Administration, and Federal Transit Administration. The revisions account for the removal of Council on Environmental Quality regulations, amendments to NEPA from the Fiscal Responsibility Act of 2023 (BUILDER Act), efficient environmental review amendments from the Infrastructure Investment and Jobs Act of 2021, and the Supreme Court decision in Seven County Infrastructure Coalition. The rule also updates monetary thresholds for certain categorical exclusions to $6,000,000 for projects receiving limited Federal funds, or $35,000,000 total cost with less than 15 percent Federal funding.
