DTSC plans to respond to Kathryn Towne today directly.

An email response was not sent to Kathryn Towne because we weren't sure if she submitted the complaint. DTSC is providing the following response:
The cleanup of the Hunters Point Naval Base follows the Comprehensive Environmental Response Compensation and Liability Act (CERCLA) guidelines. The United States Environmental Protection Agency (U.S. EPA) is the lead regulatory agency. California Department of Toxic Substances Control (DTSC), along with the support of the California Department of Public Health Environmental Monitoring Branch (CDPH-EMB) has been involved with the cleanup of the Hunters Point site since the initial investigations.
The regulatory agencies (U.S. EPA, DTSC, CDPH-EMB, and the San Francisco Regional Water Quality Control Board (SFRWQCB)) are aware of the radiological issues surrounding one of the United States Navy’s (Navy) contractors, Tetra Tech. DTSC, along with the other regulatory agencies, is working to ensure that the recent allegations from the former Tetra Tech staff person are investigated and addressed as necessary. The Navy will submit a technical memorandum to the regulatory agencies that identifies the allegations and agency concerns and, addresses how each was or will be addressed to ensure public safety. The EPA and DTSC have also requested that samples be collected where questions/concerns remain. The submittal date for this document is unknown at this time. Any further transfer of parcels will not take place until this issue has been resolved to the satisfaction of the regulatory agencies.
In regards to Parcel A, historically the majority of Parcel A was used for residences and administrative offices, not industrial activities. The only radiological materials found at Parcel A were sandblast and firebricks which were removed. These generally have naturally occurring levels of radiation. Buildings on Parcel A were scanned and no radiological contamination was found above cleanup levels. Two buildings were demolished and removed and only building 821 remains.
Groundwater monitoring continues over the entire site in both the A and B aquifers. No radiological contaminants have been found above remediation goals.
In regards to the Atomic Energy Commission regulatory guide (1.86), the Nuclear Regulatory Commission (NRC) adopted this regulatory guide when the AEC was dissolved and the NRC was formed. The guide should be referenced as NRC reg guide 1.86, which was used until August 2016. The criteria referenced under reg guide 1.86 are now referenced under NRC reg guide 8.23.
The Navy is fully complying with both the Nuclear Regulatory Commission (NRC) and U.S. EPA radiological goals, and, must meet the DTSC/CDPH goals for all buildings and soil at the site. State goals for the site are “similar to naturally occurring levels”. This has been demonstrated in radiological scanning technical memos and reports.
