EPA Comments on the SF Bay Delta Water Quality Control Plan

The following links exit the site Exit

EPA is reviewing and commenting on periodic reviews and proposed modifications to water quality standards, including flow criteria, in the San Francisco Bay/Sacramento-San Joaquin Delta Estuary Water Quality Control Plan (Bay-Delta WQCP). The State Water Resources Control Board is updating standards in the Bay-Delta WQCP two phases. Phase 1 addresses freshwater flows for the protection of aquatic life in the lower San Joaquin River and three tributaries, the Stanislaus, Merced, and Tuolumne Rivers as well as salinity limits for the protection of agriculture in the southern Sacramento-San Joaquin Delta. Phase 2 also called the "comprehensive update," addresses freshwater flow conditions in the Sacramento-San Joaquin Delta, its tributaries, and Suisun Bay to reverse population declines of commercial, recreational, and forage fisheries and broadly improve conditions for aquatic resources.
