Frequently asked questions (FAQs)

What is a 404 permit?

A 404 permit is a permit that must be obtained before any dredged or fill material may be discharged into waters of the United States. A 404 permit is issued by the U.S. Army Corps of Engineers. Dredged or fill material includes all foreign substances such as soils, rocks, coffer dams, sheet pilings, concrete, piers, etc. Waters of the United States include wetlands streams, intermittent streams, rivers, lakes, mud flats, sloughs, flowages, etc.

The intent of the 404 permit is to minimize the effect of discharging dredged or fill materials into the waters of the United States whenever it has been determined that it is not practicable to avoid the discharge. Contact the regional environmental coordinator and see FDM 21-30-1, procedure 1 for additional guidance.

When is a 404 permit needed?

A 404 permit is required before fill is placed into a wetland, stream, lake or other water of the United States. FDM 21-30-1.

What is 401 certification?

The 401 certification is a requirement of the Clean Water Act. Any 401 certification requires DNR to certify that the proposed discharge of dredged or fill materials into waters of the United States will not have a significant effect on the quality of the water FDM 21-30-1.

When is a 401 certification obtained?

The 401 certification must be obtained before the application for the 404 permit is transmitted to the U.S. Army Corps of Engineers. It is necessary, however, to get a sense of whether WDNR will grant, waive, or deny 401 certification during the environmental process of the project. WDNR should be consulted on 401 certification throughout the development of a project. Contact the regional environmental coordinator for guidance on WDNR consultations and see FDM 5-10-1.

What are the required ratios for wetland replacement?

Wetland mitigation banking technical guideline requires that wetlands be replaced at various ratios depending upon the probability of success. The ratios may be adjusted depending on the wetland affected, the location, and the type of replacement. The ratios are in appendix A of the wetland mitigation banking technical guideline; March 2002. The regional environmental coordinator should be contacted before any commitments for replacements are made.
