Water Quality Certification 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.
