Federalism Consultation Letters - Region 9

EPA is archiving material relevant to the Navigable Waters Protection Rule, including this page, to avoid confusion with the January 2023 rulemaking efforts. For information on federalism consultation for the January 2023 rulemaking, click here.

As part of the EPA and the Department of the Army’s efforts to review and revise the scope of the “waters of the United States,” the agencies have posted almost 200 comment letters that were submitted during the formal consultation process, giving the public and stakeholders the opportunity to review the input the agencies received.  A summary of issues raised during federalism and tribal consultation is available in the docket.
