Water Quality Certification Public Notices
Water Quality Certification Actions - Applicants for federal permits that involve dredge or fill activities in surface waters (including wetlands) are required to obtain certification from the state verifying that the activity will comply with state water quality standards. Most of these federal permits are referred to as 404 permits (in reference to Section 404 of the federal Clean Water Act). Applicants for some other types of federal license or permits (ex. FERC licenses) that authorize activities that may result in discharges to waters of the United States are also required to obtain state certification. This state certification is called 401 Certification (in reference to Section 401 of the Clean Water Act). In California, 401 certification actions are the responsibility of the State and Regional Water Quality Control Boards. It is the policy of this Regional Board to provide public notice of pending 401 Certification actions in order to gather comments from concerned agencies and the public. The following list contains notification of pending 401 Certification actions.

| California Department of Transportation CDOT Highway 254 PM 0.0 -43.0 Culvert Rehab Project (01-0H246) |
1B25179WNHU | Humboldt | 40.321944°N, 123.921667 °W |
The Project will construct a structure to provide fish passage at one stream crossing and rehabilitate 32 existing drainage systems determined to be Waters of the State to help decrease risk in loss of roadway due to erosion or embankment failures. Proposed culvert rehabilitation treatments include structure replacement and correcting drainage inlets and outlets. The Project will permanently impact 261 linear feet of streams and 92.16 linear feet of riparian areas and temporarily impact 1,313 linear feet of streams and 1,278 linear feet of riparian areas . Permanent impacts totalling 0.04 acres will be more than offset due to daylighting, upsizing existing culverts, and planting riparian trees and vegetation. Construction will occur over 172 working days from 2027 through 2029. All work within the stream channel (excluding revegetation work and vegetation removal by hand crews) will be conducted between May 15 and October 15. | March 26, 2026 to April 15, 2026 | Shannon Strong Shannon.Strong@waterboards.ca.gov 707-576-2499 |
