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.

To reduce the number and severity of collisions on this section of Highway 1, the Project will widen lanes, increase shoulder widths, replace centerline rumble strips, and install new guardrails. Drainage improvements include installation and replacement of end treatments and culverts with larger diameters. Of the 8-culverts, 4-culverts are jurisdictional. Temporary impacts include 200.4 linear feet, and 79.0 linear feet of permanent impacts to unnamed streams to the Pacific Ocean. Permanent impacts are offset by increased diameters  of culvert pipeline. Restoration includes reseeding and erosion control to improve vegetation coverage, and 7-bioswales will improve infiltration and treat stormwater. Project construction is planned for 130 working days within one construction season between May 23, 2022 and October 14, 2023.

Project will develop a 136-unit economically feasible residential complex on a 14.25-acre project site on Burbank Avenue between Hughes Avenue and Hearn Avenue. Project will permanently impact 0.25-acre of seasonal wetlands, which will be mitigated at a 2:1 mitigation to impacts ratio at an off-site permittee responsible mitigation site called Horn 6.

Mendocino


39.545229°N,

Project construction involves installation of three (3) debris racks above the concrete channel to catch debris and a new headwall to contain water at the drainage inlet. An existing open roadside drainage ditch will be graded to allow for overflow drainage to an existing culvert at PM 58.59. A small embankment and maintenance pullout will be constructed adjacent to the new headwall. The Project will reduce roadway maintenance work, while improving access for the safety of maintenance staff. Temporary impacts amount to 1.5 LF and .05 LF of permanent impacts to streambeds for Project construction to occur over 10 working days between May 15, 2022 to October 15, 2022.

This project will replace and upsize a 130 linear feet (LF) by 4.5-foot diameter culvert to 12-foot diameter at PM 24.98 on Hwy 3 to restore anadromous fish passage in Fraszier Creek and improve structural integrity and drainage for the roadway. Project construction includes approximately 53 LF of permanent impacts, and 330 LF of temporary impacts to waters of the US and state and 0.05 acres of temporary riparian impacts for removal of 55 trees. Areas of temporary impact will be restored with erosion control and planting of native vegetation. Permanent impacts will be mitigated by improved functions of reduced scour and increased culvert diameter. Construction will occur over 40 working days from June 1, 2022 to October 20, 2022.

Arcata Wastewater Treatment Facility Improvement Project 1B21127WNHU Humboldt 40.85518, -124.0894 The City of Arcata is proposing to replace a portion of existing the Arcata Wastewater Treatment Facility (AWTF) infrastructure and upgrade several components as part of the AWTF Improvement (project). This project will be phased as a Phase I and Phase II project. Phase II is conceptual at this time and there are no known impacts to wetlands/waters. This application is specific to Phase I elements which impact wetlands and waters. These elements include installation of buried pipe for reconfiguring the flow of the disinfected effluent from the enhancement wetlands, installing a discharge pipe into a constructed brackish marsh at the north end of the Arcata Bay section of Humboldt Bay (future outfall discharge point), and constructing a mitigation wetland area. The purpose for the proposed project is to replace aging infrastructure, improve quality of treated effluent discharged into Humboldt Bay, and meet discharge requirements. Mechanical equipment is old and no longer performing efficiently. The natural systems have reduced treatment and hydraulic capacities due to years of solids accumulation and vegetation growth. This has resulted in numerous water quality violations that must be addressed. The proposed project addresses public health needs, including improving the hydraulic and treatment capacity of the treatment facility and meeting National Pollutant Discharge Elimination System (NPDES permit requirements. The installation of UV disinfectant equipment, proposed flow reconfiguration, and new effluent limits are driving factors for this project. Permanent impacts will be limited to rock slope protection relating to hydraulic upgrades and will be mitigated for accordingly. All temporary impacts will be mitigated for onsite. 9/24/2021 - 10/15/2021 Brandon Stevens, brandon.stevens@waterboards.ca.gov, (707) 576-2377

Proposed project involves construction of a community event space, residence, and associated site improvements. 0.045-acre of wetland would be permanently filled. Compensatory mitigation at a ratio of 2:1 mitigation to impacts is proposed. Post-construction stormwater would be treated and infiltrated with LID BMPs.
