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.

| McKnight Gravel Extraction Operations Project | 1B25035WNHU | Humboldt | 40.9118°, -123.6138° | The proposed project would continue ongoing annual extraction of river run material from the McKnight gravel bar within the Trinity River. Annual extraction volumes may vary from year-to-year but would not exceed 10,000 cubic yards. Up to 10,000 cubic yards of gravel would be extracted annually from approximately 1.8 acres of the McKnight Gravel Bar. Mining would occur during the summer low-flow season. The proposed extraction period would occur between June and October 15 each year, with the annual completion date to be determined in coordination with CDFW and NOAA Fisheries. Extraction techniques may include skims, trenches, alcove extractions, and riparian enhancement extractions. The preferred extraction methods would be determined each year during preparation of the annual |

| Middle Creek Instream and Floodplain Habitat Enhancement Project | TBD | Siskiyou | 41.85062, -122.71906 | This project will produce an approximately 1,200 square foot off-channel rearing pond that will connect to the primary channel on the east bank of Middle Creek, install 15 beaver dam analog (BDA) structures within the stream channel and side channel, install 25 engineered wood structures strategically placed instream and throughout the floodplain, remove a low berm that is restricting floodplain connectivity and revegetate all disturbed soils with a diversity of native plants. | April 25 through May 15, 2025 | Jake Shannon Jacob.Shannon@waterboards.ca.gov |
| Salt Creek Floodplain Restoration Project | 1A24162WNTR | Trinity | 40.551529, -123.214133 | The goal of the project is to restore vertical and lateral hydrologic connectivity between Salt Creek, its floodplain, and adjacent groundwater aquifer to increase aquifer recharge, storage, and water quality of groundwater availability for release to the stream as baseflow. Restoring the connectivity between the stream and floodplain will also restore geomorphic function and aquatic habitat. The project also serves as a potential first phase in extending the restoration of Salt Creek further upstream. Specific project objectives include: 1. raise the channel bed elevation to: a. create a gravel channel bottom for fish spawning habitat, velocity refugia and cooler water through hyporheic flows, and b. recharge groundwater for longer flow recession with colder water inflows (extend duration of late spring/summer refugia for salmonids); 2. create high-flow velocity refugia for rearing salmonids; 3. create off-channel alcove habitat in the Log Pond outflow channel for low-velocity salmonid rearing habitat and potentially cool-water spring/summer rearing habitat; 4. reduce erosion potential to adjacent Tule Creek Road and Water Works District Access Road; 5. improve upstream channel alignment with the Tule Creek Road Bridge; 6. create a geomorphically stable and self-maintaining channel system that benefits native species; and 7. avoid increases in existing 100-year flood extents. | April 24 through May 14, 2025 | Jake Shannon Jacob.Shannon@waterboards.ca.gov |
| California Department of Transportation CDOT Highway 197 PM 3.2-4.0 & Highway 199 PM 20.3-26.5 Del Norte STAA Improvement Project (01-0N290) | 1A25012WNDN | Del Norte | DN-197: DN-199: |
The proposed Project will construct improvements at two locations along State Route (SR) 197 and five locations on United States (US) Highway 199 in Del Norte County to allow the reclassification of the SR 197–US 199 corridor as part of the STAA network of truck routes. These improvements include widening lanes and modifying curve geometry at identified locations to accommodate standard STAA-sized vehicles while maintaining and improving safety for the traveling public. Aquatic resources impacts include 886 LF of temporary impacts to streams, and permanent impacts of 42 LF to streams, and 0.187 acres of permanent impacts to riparian areas. Permanent impacts to streams will be offset by 115 LF of culvert upsizing credit, and mitigation for permanent riparian impacts includes riparian planting of 0.19 acres. Project construction will last for approximately three to six years, from spring 2026 through winter 2031. | April 18, 2025 through May 8, 2025 | Susan Stewart Susan.Stewart@waterboards.ca.gov 707-576-2657 |

The project will restore deteriorated pavement, and repair or replace guardrail, bridge approach rail, bridge deck, and drainage facilities at ten (10) jurisdictional PM locations within the overall project, which includes a total of 33 PM locations from PM 67.70 to 69.00 and PM 74.72 to T85.06. Culverts will be replaced using a cut & cover method. The project will result in temporary impacts including 0.032 acre of wetland, 427 linear feet (LF) of streams, and 0.05 acre of riparian area. Permanent impacts of 13 LF to streams will be offset by daylighting and upsizing culverts. Temporary impacts to streams will be restored at project completion, and impacts to wetlands and riparian areas will be restored by re-establishment, planting., and monitoring. The project will be in construction for approximately two years, from May 15, 2026 – October 30, 2027. | April 18, 2025 through May 8, 2025 | Susan Stewart Susan.Stewart@waterboards.ca.gov 707-576-2657 |
| Llano Road Trunk Rehabilitation Project | 1B4123WNSO | Sonoma | 38.392036°N, 122.776651°W | The project involves the rehabilitation of the existing Llano Road Trunk pipeline, which carries about two thirds of the City of Santa Rosa's wastewater to the Laguna Wastewater Treatment Plant. The project includes rehabilitation of 8,170 linear feet of the 66-inch reinforced concrete pipe and a condition assessment of existing manholes. The pipe will be rehabilitated with trenchless cured-in-place pipe lining technology. Any existing cracks will be pre-grouted to prevent leakage or frac-out of resin. An above-ground, temporary sewer bypass system made from three side-by-side 18" HDPE pipes will be constructed to allow continued flow of wastewater during the rehabilitation. A total of 0.04 acre of seasonal wetlands and seasonal wetland swales will be temporarily impacted by the project. Prior to commencement, a wetland biologist will evaluate all wetlands that will be subjected to temporary impacts and collect data related to the condition of the wetlands. At the conclusion of construction, the biologist will revisit each feature and determine if any remediation efforts are needed to return the wetland to pre-project conditions. | April 10, 2025 through May 2, 2025 | Kaete King kaete.king@waterboards.ca.gov 707-576-2848 |
