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.

| Main Street Bridge over Dutch Bill Creek - Maintenance Repair Project | 1B24039WNSO | Sonoma | 38.27546 °N, 123.00343 °W | The purpose of this Project is to structurally repair the bridge and reopen both lanes to the public. The Project involves removal of the damaged concrete column and construction of two new concrete piles that will be connected with a pile cap. If surface water is present within the channel at the time of construction, a dewatering plan will be followed, including placement of a temporary gravel work pad for access to the piles and a qualified biologist present to relocated any aquatic species present. The Project will temporarily impact 100 sq. ft of riparian area and permanently impact 0.7 sq. ft of stream channel. Temporary access areas will be restored to previous conditions and permanent impacts from the new piles will be mitigated with 2 sq. ft. of riparian plantings. The work is anticipated to take place July, 2024, and last 45 days. | April 17, 2024 through May 7, 2024 | Emma Tracy Emma.Tracy@Waterboards.ca.gov 707-576-2834 |
| North Coast Trails Project | 1B24016WNSO | Sonoma | 38.466558 °N, 123.00968 °W | The purpose of this Project is to construct two separate segments of the California Coastal Trail: the first segment is a 0.9 mile long Stewarts Point Trail, the second being 1.1 mile Kashia Coastal Reserve Trail. The Project consists of trail construction with surface drainage and wetland crossing features, staging areas, fencing, restroom and site amenities. Drainage features and crossings include drainage lens', armored crossings, clearspan bridges, and puncheon bridges. The trail alignment avoids and minimizes potential impacts to streams and seasonal wetlands on the site. Best Management Practices, such as ESA fencing around wetlands will be used during construction. The Project will permanently impact 527 SF, 86 LF of wetlands and 135 SF, 86 LF of stream channel. The Project will temporarily impact 1,400 SF, 86 LF of wetlands and 420 SF, 165 LF of stream channel. Mitigation for permanent impacts includes creation of 2,600 SF of wetlands and 280 LF of riparian enhancement. Work will occur in the dry season of 2024 and 2025. | April 12, 2024 through May 3, 2024 | Emma Tracy Emma.Tracy@Waterboards.ca.gov 707-576-2834 |
