Cal. Code Regs. tit. 23 § 3919.8
On December 10, 2008, the San Francisco Bay Regional Water Quality Control Board adopted Resolution No. R2-2008-0103 amending the Water Quality Control Plan for the San Francisco Bay Region. This amendment establishes a Total Maximum Daily Load (TMDL) for sediment in Sonoma Creek and an implementation plan to achieve the TMDL and related habitat enhancement goals.
The TMDL allocates discharges of sediment to natural erosion processes, non-point sources generated by human actions (e.g., roads, vineyards, grazing, and accelerated bed and bank erosion along Sonoma Creek), and point sources that occur as a result of urban runoff and wastewater discharges. The amendment is also expected to enhance stream habitat attributes including habitat complexity, fish passage, and stream baseflow.
The amendment includes an implementation plan requiring several control measures by responsible parties including developing and submitting various reports of waste discharge and management plans to address sediment loading. To implement required control measures, the San Francisco Bay Water Board will rely on compliance by responsible parties with the implementation measures specified in the Basin Plan Amendment and on Waste Discharge Requirements, Waivers of Waste Discharge Requirements, Clean Water Act Section 401 certifications, and existing NPDES permits for urban stormwater runoff and/or wastewater discharges. Every five years years, the San Francisco Bay Water Board commits to evaluate monitoring results and assess progress made towards attaining targets and load allocations.
