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.

McKee Creek Habitat Restoration and Forest Thinning Project 1B24053WNHU Humboldt 40.081528, -123.95133 This Project will improve habitat for Coho salmon and steelhead in Mckee Creek, an important salmon bearing tributary in the Mattole River headwaters by addressing the limiting factors of low summer stream flows, poor summer rearing habitat, and lack of winter refuge habitat. The Project will enhance instream and floodplain habitat by raising the stream bed to engage flows with the floodplain, increasing pool depth, and adding instream habitat complexity through wood placement. Log weirs with sub-surface clay barriers will elevate the water table and increase channel complexity. Enhancing the riparian ecosystem is also expected, with increased diversity and abundance of riparian plants in response to the higher water table. The project is designed to restore natural processes over the long-term, promoting sediment deposition and formation of a complex meandering stream with adjacent floodplain wetlands. Further, by increasing the bed elevation of McKee Creek at strategic locations throughout the Project extents, conducting grading to increase floodplain engagement, installing subsurface clay barriers on the upstream side of proposed log weirs, and reducing incision rates, the project is expected to result in additional detained runoff during the wet season leading to higher spring and summer base flows. Finally, Project objectives also include increased diversity of the riparian area and reduced evapotranspiration along with improved groundwater, streamflow and fire resiliency which will be achieved through strategic forest thinning treatments. Thinning specifications will be developed to support accelerated recruitment of large wood through release of conifers, increased diversity and healthy matrix of hardwood and conifer species, consideration of indigenous forest stewardship practices, climate change, and evolving forest management science.

CDOT Highway Highway 1, Estero Americano Coastal Preserve Mitigation Project Project (04-20950)
1B24020WNSO Sonoma 38.303875°N,
123.006822°W
The Project provides compensatory mitigation for the loss of wetlands and riparian habitat resulting from the Estero Americano Creek Bridge Replacement project on State Route (SR) 1, which required 2.2 acres of riparian planting and establishment of 0.95 acres of seasonal wetlands as off-site compensatory mitigation for impacts due to bridge construction. Riparian mitigation includes 1.97 acres of re-establishment, 0.10 acres of rehabilitation, and 1.55 acres of enhancement. Wetland mitigation includes 0.97 acres of establishment, 0.61 acres of rehabilitation, and 0.35 acres of enhancement. In addition, the Project will provide mitigation to offset permanent impacts for the Marin State Route 1 Capital Preventive Maintenance Project (EA: 04-1J960) which requires enhancement of 0.0035 acre of wetland, 0.0005 acre of stream channel, and 0.027 acre of riparian habitat. Temporary impacts resulting from the Project include approximately 0.75 acre of wetlands, 0.88 acre of reservoir, 0.85 acre (1,956 liner feet) of streams, and 0.11 acre of riparian areas. Project construction is planned from August 1, 2024, to October 15, 2025, with work occurring over four months. May 9, 2024 through May 29 Susan Stewart

Upper Conner Creek Channel Rehabilitation Project 1A15175WNTR Trinity 40.747575, -123.0635669 The proposed Project would restore the aquatic habitat and geomorphic processes associated with the Upper Connor Creek segment of the Trinity River to ecological reference condition. The Project would implement a number of rehabilitation activities to reestablish the floodplain connection to the river corridor. Project activities may include: recontouring the channel and floodplain lowering, revegetation, placement of large wood, and placement of alluvial materials. More specifically, the Project would lower the floodplain surface so that it is inundated at flows ranging from 500 cfs to 3,500 cfs and would include the addition of large wood features, and construction of in-channel features including riffles, medial bars, and lateral bars to increase mainstem complexity and raise the low-flow water surface elevation.
