In response to requests from states and tribes, EPA is seeking to clarify requirements for assumption of the CWA 404(g) permit program, reduce barriers to assumption, and place more states and tribes in the decision-making position on certain dredge and fill permits. The proposed rule will address the procedures and criteria EPA will follow in approving, reviewing, and the administration and oversight of state and tribal programs under CWA section 404(g) and EPA's implementing regulations at 40 CFR part 233.
