Hunters Point Shipyard: Radiological Remediation
The Navy is responsible for environmental remediation and clean-up of the Hunters Point Shipyard (Shipyard). The Navy’s clean-up is overseen by the U.S. Environmental Protection Agency (U.S. EPA), the California Department of Toxic Substances Control (DTSC), and the Regional Water Quality Control Board (RWQCB). Once clean-up is complete, the Navy transfers clean property to the Office of Community Investment and Infrastructure (OCII) for redevelopment, including housing, parks, and commercial space. OCII will not accept any property until the oversight agencies listed above and the San Francisco Department of Public Health (SF DPH) confirm the property is safe and ready for transfer and redevelopment. Public safety and environmental protection are the highest priority as the Navy and the oversight agencies conduct investigation and clean-up work at the Shipyard.
The Navy identified discrepancies in some radiological soil samples taken by the Navy’s contractor Tetra Tech in 2011 and 2012. The U.S Nuclear Regulatory Commission investigated these discrepancies and in 2016 fined the Navy's contractor for falsifying some soil samples. In addition, in 2016, former contract employees at the Shipyard responsible for collecting samples and performing measurements of radioactivity during the same timeframe have claimed:
· Potentially contaminated soil samples were swapped for clean soil samples
· Potentially contaminated soil was placed into open trenches in other areas around the Shipyard; and
· Computer data regarding radiation levels were tampered with to indicate lower levels of radiation.
In response, the Navy and oversight agencies are taking extensive action to identify any remaining environmental issues that may not have already been addressed, including a comprehensive investigation and the review and analysis of over 70,000 soil sample results. The Navy will publish initial findings from their review in Summer 2017.
Parcel A, the “Hilltop” Neighborhood, which is now occupied by residents, workers, and visitors, is NOT implicated by these claims. The Navy and U.S. EPA have confirmed the following areas are safe through conducting a very thorough regulatory review process:
· Parcel A: Including homes, parks, artists studios, and the commercial kitchen
· Parcel B: Artists’ studios
· Parcel E-1: SF Police Department Crime Lab in Building 606
