California Department of Fish and Game U.S. Fish and Wildlife Service Section 3.3. Water Quality State Plans, Programs, and Policies The provisions of the McAteer–Petris Act and regulatory authority of the San Francisco Bay Conservation and Development Commission are summarized in Section 3.2, Surface-Water Hydrology, Tidal Hydraulics, and Sedimentation. Porter–Cologne Water Quality Control Act and State Water Quality Control Board The Porter-Cologne Act established the State Water Resources Control Board (State Water Board) and divided the state into 9 regional basins, each with an RWQCB. The State Water Board is the primary state agency responsible for protecting the quality of the State’s surface and groundwater supplies. The Porter-Cologne Act authorizes the State Water Board to draft state policies regarding water quality. In addition, the Porter-Cologne Act authorizes the State Water Board to issue Waste Discharge Requirements (WDRs) for discharges into state waters. The Porter-Cologne Act requires that the State Water Board or the RWQCB adopt water quality control plans (Basin Plans) for the protection of water quality. The Basin Plans also provide the technical basis for determining WDRs, taking enforcement actions, and evaluating clean water grant proposals. San Francisco Bay Regional Water Quality Control Board Water quality in streams and aquifers of the region is guided and regulated by the San Francisco Bay Regional Water Quality Control Board (RWQCB). The San Francisco Bay RWQCB has primary authority for ensuring that water resources are protected from degradation by pollutant discharges. To develop water quality standards that are consistent with the uses of a water body, the RWQCB attempts to classify historical, present, and future beneficial uses as part of the Basin Plan. The Basin Plan is periodically reviewed and updated pursuant to the Porter- Cologne Act. The San Francisco Bay RWQCB adopted the most recent Basin Plan, with all amendments approved by the Office of Administrative Law, in January 2007 (San Francisco Bay Regional Water Quality Control Board 2007). The Basin Plan has adopted the following objectives, which may apply to the proposed wetland restoration, to protect water resources: • Waters shall not contain biostimulatory substances in concentrations that promote aquatic growths to the extent that such growth causes nuisance or adversely affects beneficial uses. • Waters shall not contain chemical constituents in concentrations that adversely affect beneficial uses. • Waters shall be free of discoloration that causes nuisance or adversely affects beneficial uses. Sears Point Wetland and Watershed Restoration Project Final Environmental Impact Report/Environmental Impact Statement 3.3-2 April 2012
California Department of Fish and Game U.S. Fish and Wildlife Service Section 3.3. Water Quality • No pesticide or combination of pesticides shall be present in concentrations that adversely affect beneficial uses. • Discharges shall not result in pesticide concentrations in bottom sediment or aquatic life that adversely affects beneficial uses. • Persistent chlorinated hydrocarbon pesticides shall not be detectable in water within the accuracy of the analytical methods approved by the EPA. • The suspended sediment load and suspended sediment discharge rate of surface waters shall not be altered in such a manner as to cause nuisance or adversely affect beneficial uses. • Waters shall not contain suspended materials in concentrations that cause nuisance or adversely affect beneficial uses. • Groundwater shall not contain chemical constituents in concentrations that adversely affect beneficial uses. The Basin Plan also restricts increases in water temperature and reduction of dissolved oxygen concentrations, especially in water bodies supporting coldwater aquatic organisms. Finally, the RWQCB is required to identify water bodies that do not meet water quality objectives pursuant to Section 303(d) of the CWA. See further description of CWA Section 303(d) impairments under “Regional Water Quality Conditions” below. Waste Discharge Requirements Beneficial uses of the major rivers and groundwater basins, along with narrative and numerical water quality objectives, are established in the Basin Plan for the region (San Francisco Bay Regional Water Quality Control Board 2006X7). Beneficial uses of surface water in the Project area include municipal and domestic supply; agricultural supply; industrial service supply; groundwater recharge; contact and non-contact recreation; warm, freshwater habitat; cold, freshwater habitat; wildlife habitat; migration of aquatic organisms; and spawning, reproduction, and or early development. Beneficial uses of groundwater throughout the region include municipal and domestic supply, agricultural supply, and industrial service supply. The San Francisco Bay RWQCB establishes WDRs to protect those beneficial uses identified in the Basin Plan. Beneficial uses protected by the Basin Plan that would be applicable to the proposed wetland restoration include wildlife and fish habitat, estuarine habitat, and preservation of rare and endangered species. In establishing WDRs, the RWQCB considers the potential impact on beneficial uses within the area of influence of a discharge and the existing quality of receiving waters based on the appropriate water quality objectives. WDRs issued for a project based on water quality objectives may contain moreor less-restrictive conditions that take into account factors such as economic considerations in addition to actual and potential beneficial uses. Because San Pablo Bay is considered a “water quality limited segment” in the Basin Plan, Sears Point Wetland and Watershed Restoration Project Final Environmental Impact Report/Environmental Impact Statement 3.3-3 April 2012
