Interior Department Refines NEPA Handbook Procedures

## Summary

The Department of the Interior is updating its rules for how it follows the National Environmental Policy Act (NEPA). They’re moving some procedures into a separate handbook to keep things clear and simple, affecting only their own internal work. This change is happening now, and they’re asking for public feedback before finalizing it.

## Abstract

The Department of the Interior (Department or DOI) is partially rescinding and making necessary targeted updates to its remaining regulations implementing the National Environmental Policy Act (NEPA), which were promulgated to "supplement" now-rescinded Council on Environmental Quality (CEQ) NEPA implementing regulations. Mindful that the Supreme Court recently clarified NEPA is a "purely procedural statute," DOI will henceforth maintain the remainder of its NEPA procedures--which apply only to DOI's internal processes--in a Handbook separate from the Code of Federal Regulations (CFR). This interim final rule requests comments on this action and related matters to inform DOI's decision-making.
