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 3 PM 25.24 Hayfork Mountain Culvert 2 Project (02-0J170)




This project will upsize a 5-foot diameter culvert to12-foot diameter at PM 25.24 to restore passage for anadromous fish in Fraszier Creek and re-establish structural integrity and proper drainage for the roadway. Project construction will cause approximately 36.1 linear feet of permanent impacts, and 315.4 linear feet of temporary impacts to waters of the US and state. Areas of temporary impact will be restored with erosion control and planting of native vegetation. Permanent impacts will be mitigated by improved functions due to reduced scour and increased culvert diameter. Construction will occur over 98 working days from June 1, 2022 to October 20, 2022.
