More information about these meetings, including a complete schedule and the Federal Register notice, can be found at EPA's Pre-Proposal Outreach Meetings webpage.

Federalism and Tribal Consultation - In Spring 2017, EPA, in coordination with the Department of the Army, initiated formal consultations to solicit comments from state, local, and tribal governments regarding such a new definition. The agencies held a series of meetings with various groups as part of the consultation processes and have posted for public review each of the letters received as part of the consultation processes. ​Summaries of issues raised during tribal and federalism consultation are available here in the docket.
