The purpose of this Council on Environmental Quality Memorandum is to establish a revised report to ensure that all Federal agencies are consistently reporting designation of Federal and non-federal cooperating agencies in the preparation of analyses and documentation required by the National Environmental Policy Act (NEPA). This document supersedes the reporting section of Cooperating Agencies in Implementing the Procedural Requirements of NEPA (2002). See that Guidance for the full CEQ discussion of cooperating agencies in NEPA.
