2016 Updated ambient concentrations of toxic chemicals in San Francisco Bay area sediments

 The purpose of this memo is to communicate the most recent results for the ambient concentrations of mercury, Total PAHs and Total PCBs in San Francisco Bay area sediments.  Regulation of dredging and dredged material disposal or reuse under the San Francisco Bay Long Term Management Strategy for Dredging (LTMS) involves, in part, evaluation of sediment chemistry characteristics. For dredged material in California, for most chemicals, there are no numeric sediment quality standards or objectives that define chemical suitability for disposal or reuse at particular placement sites.1 Consequently, Bay dredged sediments are compared to various published screening values and other guidelines, to reference site chemistry, and where available and appropriate, to ambient sediment contaminant concentrations for the Bay as a whole. Therefore, starting in 2011, the LTMS agencies have asked SFEI to calculate the ambient concentrations for a small subset of sediment contaminants that are either subject to TMDL limits for in-Bay dredged material disposal or are relevant for bioaccumulation testing for dredging (DMMO, n.d.).

On November 7, 2017, the State Water Resources Control Board adopted an order accepting an agreement defining the state’s commitment to stabilize and manage the Salton Sea to protect public health and critical Pacific flyway habitat.  Order WR 2017-0134 outlined the State Water Board’s oversight role in monitoring and ensuring progress toward the goals of the Salton Sea Management Plan (SSMP), which sets annual milestones for habitat restoration and dust-suppression projects over the next 10 years.

Improving air quality and creating habitat at the Salton Sea are key priorities for Governor Gavin Newsom and the California Natural Resources Agency. The Sea’s continuing decline in elevation and resulting exposure of lakebed negatively impact surrounding communities and reduce remaining habitat for fish and wildlife. The California Natural Resources Agency, the California Department of Water Resources, and the California Department of Fish and Wildlife (together, the State Team) are focused on implementing the Salton Sea Management Program’s (SSMP’s) 10-Year Plan to improve conditions by constructing 30,000 acres of habitat and dust suppression projects around the Sea.

The Salton Sea Management Program (SSMP) made progress in 2020 toward reducing exposed lakebed and creating habitat at the Salton Sea (Sea). Even amid challenges posed by the global COVID-19 pandemic, delivering projects that improve conditions for residents as well as wildlife at the Sea remains a key priority for the Newsom Administration. The SSMP worked closely with local, State, Tribal and federal partners to advance important work in 2020 and is poised to build on that momentum in 2021.

The Salton Sea Management Program (SSMP) made significant progress in 2021. It broke ground on the largest restoration project in the Sea’s history, advanced with partners several other community-oriented restoration projects around the Sea, started important vegetation management work on exposed lakebed to reduce dust emissions, and secured commitment from state leaders for an additional $220 million in funding. This was made possible through partnerships with many other entities and by growing the SSMP Team, including several critical new hires.

2022 was a year of visible progress and momentum for the Salton Sea Management Program (SSMP) and partners. The first large-scale restoration project in the Sea’s history achieved major construction milestones, while community-oriented projects and vegetation enhancement made headway around the Sea in collaboration with state, federal and local entities.

Significant, measurable progress continued at the Salton Sea (Sea) over the last year. The largest restoration project in the Sea’s history neared completion, suppressing dust and restoring habitat across thousands of acres at the south end of the Sea. In other areas along the Sea, hundreds of acres now host native vegetation recently planted to suppress dust over coming decades. These plants have taken root, are growing and are beginning to serve their purpose. This year also witnessed the first major investment by federal agencies to stabilize the Sea; the U.S. Bureau of Reclamation (Reclamation) granted $70 million to accelerate local restoration projects.

The State's Salton Sea restoration and management efforts continued to show significant, demonstrable progress in 2024 – achieving key milestones and accelerating the pace of critical project delivery functions. With new federal funding, the Salton Sea Management Program (SSMP) broke ground to expand what was already the largest restoration project in the Sea’s history, and further expansion is being initiated to suppress dust and restore habitat on up to 9,000 acres at the south end of the Sea. In other areas along the Sea, over 1,300 acres — spanning roughly five miles of shoreline — now host native vegetation recently planted to suppress dust over the coming decades.
