Under CWA section 404, a permit is required before dredged or fill material can be discharged into waters of the United States, including certain wetlands. Section 404(g)(1) of the CWA provides states and tribes the option of administering the CWA section 404 permit program in certain waters within the state's or tribe's jurisdiction, respectively. To date, only Michigan and New Jersey have assumed administration of the section 404 program -- the Army Corps of Engineers retains permitting authority for the rest of the country. In response to requests from states and tribes, EPA is seeking to clarify assumption requirements, reduce barriers to assumption, and place more states and tribes in the decision-making position on dredged and fill permits. The proposed rule will address the procedures and criteria EPA will follow in approving, reviewing, administration and oversight of state and tribal programs under CWA section 404(g) and EPA's implementing regulations at 40 CFR part 233.
