Overview of the Assumption Process
Step 2 – Hold Dialogue prior to Assumption Request - Confer with EPA regional and headquarters staff on pre-request steps, process, and substantive requirements; review existing state or tribal programs, laws, and resources and identify program modifications and/or legislation needs; conduct outreach with the public and regulated community; obtain feedback from U.S. Army Corps of Engineers (Corps) on waters the Corps will retain; reach out to affected Tribes and States regarding notification and coordination; and reach out to the National Marine Fisheries Service and the U.S. Fish and Wildlife Service regarding federally listed species.
Step 3 – Develop and Submit Assumption Request Package – Submit a letter from the Governor or equivalent tribal leader requesting program approval; a complete program description; a statement from the Attorney General or tribal equivalent; a Memorandum of Agreement with the respective Regional Administrator; a Memorandum of Agreement with the Secretary of the Army; and copies of all applicable state or tribal statutes and regulations, including those governing applicable state or tribal administrative procedures.
Step 4 – EPA Review and Approval – EPA reviews request package; publishes a notice of the request for public comment; conducts federal agency review; holds a public hearing; and documents its review and decision.
