Navy's perspective on the completion of radiological scans for Parcel A-1
Statement: The California Department of Public Health (CDPH) surface scans of Parcel A-1 were completed on October 26, 2018, and the information collected confirms that the area was not used for work involving radiological materials. The scan did not find any soil contamination or evidence of radiological activities.
Most importantly, the scan's extremely detailed and sensitive methodology reinforced the fact that Parcel A is safe. The lone historical Navy object found was a naval deck marker, which was buried under approximately 10 inches of soil, at the bottom of the hill on the north side of Parcel A-1, in an undeveloped and fenced area. This deck marker would not have resulted in a health or safety hazard to anyone who happened to be at that spot previously. The Navy appreciates that CDPH undertook this effort.

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.

Navy response about external reports questioning validity of the HPNS Historical Radiological Assessment.
Statement: The Navy's Historical Radiological Assessment (HRA) covers 64 years of radiological history from 1939 to 2003 at the former Hunters Point Naval Shipyard (HPNS) and is based on expert analysis by the Navy of thousands of historical records and over 150 interviews with people who worked at HPNS. The HRA was prepared by the Navy and was reviewed with applicable State and Federal regulators, including the U.S. Environmental Protection Agency, California Department of Public Health, California Department of Toxic Substances and Control, San Francisco Department of Public Health, and the Nuclear Regulatory Commission. Recent reports from outside groups on the quality of the HRA do not provide any new factual evidence to challenge the conclusions of the HRA.
The Navy has full confidence in the HRA for Hunters Point as being an accurate and reliable evaluation of impacted radiological sites that have been or are slated for cleanup to ensure the property is suitable for transfer to the City of San Francisco and protective of public health.
Details about the radiological cleanup of HPNS, including the HRA, are available at: bracpmo.navy.mil/hpnsrc.

Navy response to claims about the radiological cleanup at Hunters Point
Statement: on March 16, 2018, the representative for a former Tetra Tech EC employee contacted EPA Region 9 about claims regarding the radiological cleanup program at Hunters Point. Representatives of the Navy and EPA met with the two parties on May 17, 2018 to visit the site and document their statements. Thereafter, the Navy reviewed the information and developed responses for each claim as follows.
C1: The concentration of Radium-226, from samples collected at Parcel A, are above the Soil Cleanup Levels according to lab reports provided by the reporting parties.
R1: The Navy has reviewed these lab reports and determined the Radium-226 concentrations are consistent with ordinary brick and concrete samples.
C2: Four keel blocks (previously used at Hunters Point) have been placed near the Lennar Welcome Center at Parcel A as landscaping accents. Keel blocks were considered rad-impacted or potentially contaminated because they may have been used during decontamination of Operation Crossroads naval vessels in dry docks.
R2: The keel blocks were scanned and released as safe. The Navy allowed Lennar to use the keel blocks because they represent shipyard history. They have been rescanned and affirmed safe as part of the radiological health and safety scan being conducted at Parcel A by the California Department of Public Health.
C3: A former worker claimed that a soil sample collected near the corner of Fisher and Spear Streets was analyzed and had a Cs-137 concentration of about 3 picocuries per gram (pCi/g), which was well above the cleanup level being used (0.113 pCi/g).
R3: The area identified is located on Parcel UC-1. It will be thoroughly evaluated using soil borings as part of the retesting of the UC Parcels. Soil samples will be collected at the surface and at intervals likely down to shallow bedrock. Additionally, as part of the chemical remediation efforts in 2012, after the claimed soil sample was collected, the Navy removed the surface soil and replaced it with clean import fill.
C4: The Reporting party indicated observing a dump truck carrying wet soil in February 2018 from Parcel E to a soil stockpile being used by the developer (FivePoint) on Parcel A.
R4: In February 2018, Parcel E-2 (not Parcel E) soil activities were being conducted by the Navy’s Parcel E-2 contractor. The Navy’s contractor was questioned and has indicated that all soil is being reused onsite as a foundation layer for Parcel E-2 and that soil has not been transported to Parcel A. The Navy’s independent 3rd party oversight contractor has verified that soil did not leave Parcel E-2.

Update on Parcel A scanning
Statement: After completing about 90% of scanning activities on Parcel A-1, information collected continues to confirm that area is safe. California Department of Public Health technicians have identified and investigated anomalous readings at twenty eight locations. Twenty seven of the anomalous readings were determined to be caused by naturally occurring radiological constituents found in landscaping materials, such as wood chips and fertilizer.

Comments regarding the Draft Work Plan for Retesting Parcel G.
Statement: As part of our efforts to include community and regulatory stakeholder input in developing the path forward for Hunters Point, the Navy is pleased to have received comments on the Draft Work Plan for Retesting Parcel G. Data collected will be used to determine whether the site conditions at Parcel G meet original cleanup objectives and the land is suitable for transfer to the city, or if additional work (including excavation and sampling) is required.
The Navy is committed to conducting 100% of needed remediation if remaining contamination is found.
The Navy will be evaluating the comments received and, as appropriate, incorporate them into a Draft Final Work Plan. The Navy and regulatory agencies will then work together to ensure that the Draft Final Work Plan is legally and technically complete, and initiate the Parcel G retesting program. The Navy appreciates all community and regulatory input on its documents and looks forward to finalizing the Work Plan to enable data gathering at Parcel G as soon as possible.

Information about the drinking water system at Building 606.
Statement: Potable water at Hunters Point is supplied by the San Francisco Public Utilities Commission and has been confirmed by the San Francisco Department of Public Health as being safe for consumption. If not used, water can sit in pipes for an extended amount of time potentially resulting in discoloration and a higher mineral content which could affect the taste.
Also, when water sits idle in older distribution systems that used copper pipes and lead-based solder, it is possible that these metals could slowly dissolve into the water to levels that exceed drinking water standards. As a preventative measure, EPA recommends cycling water through the pipes, at the tap, for a short period to flush the system.
In February 1997, the San Francisco Police Department began moving into Building 606. On March 6, 1997, an industrial hygienist sampled water at Building 606 and determined that the water was safe to drink (the report with this information was completed on March 24, 1997). A total of nine water sampling events took place between March 1997 and Sept 1999 at Building 606, all found that the water was safe to drink.

Navy response to media queries regarding Rep. Pelosi’s July 27, 2018 press release at: https://www.democraticleader.gov/newsroom/72718/
Statement: "The Office of the Naval Inspector General received Rep. Pelosi's letter and will respond in an appropriate time and manner to address the concerns she presented. It would be inappropriate to comment on this matter any further at this time. Throughout the Hunters Point cleanup and transfer process, the Navy has adhered to regulatory cleanup standards established by the USEPA and other public agencies, following principles that are protective of the public. Transparency in the cleanup and re-testing process at Hunters Point is a goal Navy shares with Rep. Pelosi to ensure the property is suitable for transfer and the public is protected," said Lt. Cmdr. Ryan de Vera, U.S. Navy spokesman.

The Navy has prepared a work plan for radiological retesting at Parcel G on HPNS which is available for public comment during a 60-day period beginning June 15, 2018.
Statement: The Navy will collect new data at sites where TtEC had previously gathered radiological data. Cleanup objectives for each parcel were developed early in the Superfund process to prevent exposure to possible radiological contamination in existing soil and buildings, as documented in the Record of Decision (ROD). The rework to collect new data will begin with Parcel G. This new data, including results from soil and buildings that remain at the areas in question, will verify if the property is suitable for transfer. If the new data does not verify the property is suitable for transfer, subsequent work plans will be developed for any additional work and next steps. The public is encouraged to review and comment on the Parcel G work plan (link below) during the 60-day public comment period (June 15, 2018 - August 14, 2018). Written comments to the work plan may submitted to firstname.lastname@example.org

On 9 May Tetra Tech released information indicating that the Navy has shown interest in their proposal to pay for an independent party to retest for radiological contamination at the Hunters Point Shipyard.
Statement: Independent retesting is a critical element of the Navy's Hunters Point reevaluation workplan. We believe it to be necessary to provide a comprehensive, credible data set to reassure the community about their safety as well as determine the extent of any remediation activities needed to complete the cleanup of HPNS. Tetra Tech has made a broad public offer to pay for retesting; the Navy requires a more concrete and specific proposal to evaluate the appropriateness of their offer. The safety of the HPNS residents is the Navy's highest priority, so the retesting must be carried out to the highest standard by a READ MORE>
