  3. Where can Tribes, States and stakeholder groups read the public comments from the rulemaking process?

  5. What can Tribes or States do to prepare for assumption?
    • There are many resources available on the CWA Section 404(g) website that will help a Tribe or state explore assumption, including materials on the 2024 Rule (preamble, revised regulations and fact sheets), and information on developing and funding a feasibility study to evaluate the costs and benefits of assuming the Section 404 program. The EPA can also provide technical assistance for questions related to assumption and a feasibility study. Please contact the EPA by reaching out to us at cwa404g@epa.gov.
  6. For Tribes or States not interested in assumption, what is their role?
    • Tribes and states play a critical role in protecting our nation’s waters. There are several opportunities for Tribes and states to get involved without assuming the Section 404 program, including establishing a Tribal or state dredged or fill material permitting program distinct from the CWA program, developing a State Programmatic General Permit and developing a wetland program plan.
