Chevron USA, Inc. (Chevron) owns and operates a petroleum refinery in Richmond, California. Prior to 1987, the refinery discharged wastewater directly into Castro Cove, a small embayment within San Pablo Bay. Although the wastewater discharge was relocated outside of Castro Cove in 1987, some of the sediments inside the Cove had elevated levels of contaminants, including mercury and polycyclic aromatic hydrocarbons (PAHs). In 2007 and 2008, Chevron complied with an order issued by the California Regional Water Quality Control Board and removed the most contaminated sediments within Castro Cove. Chevron also accepted the Trustees’ invitation to conduct a cooperative Natural Resource Damage Assessment (NRDA). The goal of the NRDA was to assess injuries to natural resources and plan restoration to compensate for the injuries. The Trustees reached a settlement with Chevron in 2010. The settlement provided $2.85 million for implementation, monitoring and oversight of tidal restoration projects. Projects that improved the ecological function of impaired tidal marsh habitats in San Pablo Bay would compensate for the loss of natural resource services resulting from the contamination of sediments in Castro Cove. The Trustees, with input from the public, selected two restoration projects in the Final Damage Assessment and Restoration Plan/Environmental Assessment (June 2010). The Trustees provided funds for restoration at 1) East Bay Regional Park District’s Dotson Family Marsh Restoration project (formerly Breuner Marsh) and 2) the U.S. Fish and Wildlife Service’s Cullinan Ranch Restoration project. Both projects restored tidal wetlands similar to the habitats injured in Castro Cove. All of the settlement funds have been spent.
