CWA §401 Certification - New
On June 1, 2020, the U.S. Environmental Protection Agency (EPA) finalized the Clean Water Act (CWA) Section 401 Certification Rule (40 CFR Part 121) to update and clarify the procedural requirements for water quality certification under CWA §401. Additional information, including the full text of the Final Rule is available on EPA's website. The Final Rule became effective on September 11, 2020.
If you are required or have been notified that your project requires that you request a water quality certification under CWA §401 from DEC for any activity that may result in a discharge to waters of the United States, then in accordance with 40 CFR §121.4 you must request a Pre-Filing Meeting with DEC at least 30 days prior to submitting a certification request.
To request a Pre-Filing Meeting Request, complete the Pre-Filing Meeting Request form and email to DEC-401Cert@alaska.gov. Include in the subject line the following "Pre-filing Meeting Request - CWA §401 Certification - [project title]". Include as much information about your project as possible, and identify if you have any particular issues you wish to bring to DEC’s attention. While DEC is not obligated to grant the request, you may not file a request for certification from DEC until you have filed a Pre-Filing Meeting request with DEC and 30 (thirty) days have passed.
To request a CWA §401 certification, complete the CWA §401 Request for Certification form and email to DEC-401Cert@alaska.gov along with the federal permit application and support materials. Include in the email subject line the following: “CWA §401 Certification Request - [Federal Agency and permit number or license number] - [project title]". It is important that you have allowed 30-days to have passed from requesting a prefiling meeting request. DEC does charge a fee for processing CWA §401 certifications, see Permit Fees website.
Several federal and state agencies are involved in Section 404 permitting.

The State of Alaska includes approximately 63% of the nation's wetland ecosystems (Hall et al. 1994). Estimates place the total acreage at approximately 130 million acres or about one-third of the State. Wetlands help maintain water quality by slowly filtering excess nutrients, sediments, and pollutants before water seeps into rivers, streams, and underground aquifers. They also offer a breeding ground and/or habitat for fish, wildlife, and plants. Wetlands are areas that are inundated or saturated by surface or ground water at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions. Wetlands generally include tundra, permafrost areas, marshes, bogs, and similar areas.
