Navy response about external report on Hunters Point Naval Shipyard Cleanup Standards

Statement: The Navy's first priority in its Base Realignment and Closure cleanup work at Hunters Point is human health and safety. We stand by our existing clean-up goals at Hunters Point, which (are some of the most conservative in the BRAC program and) have in the past been confirmed by expert review across multiple regulatory agencies to be protective of human health.  While different methodologies can be used to calculate goals and risk, the Navy has consistently evaluated EPA risk criteria, leveraged their expert guidance in our calculations, and we work together toward the same goal of ensuring that the property is suitable for transfer and reuse by the City of San Francisco.

As part of the 5-year review process, the Navy evaluates past remedial actions to determine if they remain protective.  Consistent with regulatory agency and public comments on the July 9 draft 2018 5-Year Review, using current risk assessment procedures and guidance, the Navy evaluated the protectiveness of past remedial action levels and will present Navy draft calculations in the 2018 5-year Review.  The next version is expected to be distributed to the public and regulators for further review in November 2018. The referenced EPA comments were accepted by the Navy and the EPA's Preliminary Remediation Goal (PRG) calculator was used to evaluate protectiveness of Navy remedial goals.
