Parcels UC-1 & UC-2 Draft Finding of Suitability for Transfer
This fact sheet provides a brief summary of the draft finding of suitability for transfer (FOST) of Parcel UC-1 and for transfer of Parcel UC-2 of the Hunters Point Shipyard Superfund Site. The report was prepared by the U.S. Navy. The FOST was prepared to document the readiness of the parcels to be transferred to the San Francisco Redevelopment Agency (SFRA) according to all relevant and appropriate state and federal regulations including the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), known as Superfund. The report also describes the readiness of the property for reuse with regard to laws regulating lead paint, asbestos, petroleum, and other hazardous materials not covered by Superfund law. The Navy is required to clean up contaminants that it spilled but does not usually do lead paint or asbestos abatement in buildings. That cleanup will be done by the new owners according to regulations that govern these substances. However, the Navy must disclose what it knows about these other contaminants as part of the FOST report.
This FOST is different from a Finding of Suitability for Early Transfer (FOSET) because the FOST documents that all Navy cleanup has been completed to the satisfaction of the state and federal agencies. A FOSET such as the one described for Parcels B & G in an earlier Fact Sheet describes what remains to be cleaned up, not by the Navy, but by the new property owners under the watchful eyes of the same regulatory agencies. The transfers of UC-1 & UC-2 are not early transfers.
Public involvement is a requirement of the Superfund process. The U.S Environmental Protection Agency's Technical Assistance Grant program provides fact sheets such as this one to inform communities near Superfund sites to assist their understanding and participation in the process.
Site Description and History
The Hunters Point Shipyard Site (HPS) is located on 866 acres on the west side of San Francisco Bay in San Francisco, California. About half of the site area is on land and half is under water. The site was used as a shipyard since the late 1800s. Beginning in 1940, the U.S. Navy used the HPS for a variety of purposes including shipbuilding, maintenance and repair of ships and submarines, and decontamination, storage, and disposal of radioactive and radiation testing materials. Over its years of use, HPS became contaminated with a variety of hazardous substances, causing it to be listed on the Superfund National Priorities List in 1989. The U.S. Navy is remediating the shipyard under the regulations of the Superfund law: the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). Parcels UC-1 and UC-2 are two of several parcels into which the site has been divided to speed up cleanup and transfer of the property to the San Francisco Redevelopment Agency.
Parcels UC-1 & UC-2 are 3.9 acres each. Parcel UC-‐1 includes a portion of Spear Avenue. It is almost completely paved and includes Buildings 819 and 823, asphalt parking lots, and a small hillside area. Parcel UC-‐2 includes parts of Fisher Avenue and Robinson Street and a triangular shaped parking area for Building 101.
Contamination at Parcels UC-1 & UC-2
The FOST identifies the following conditions, actions taken, and notifications required for these parcels: presence of hazardous substances, CERCLA/RCRA, asbestos containing material (ACM), and lead based paint (LBP). These conditions did not apply to UC-1 and UC-2:
petroleum products, above-‐ and below-‐ground storage tanks, munitions and explosives, or polychlorinated biphenyls (PCB).
Hazardous Substances: Oils and paints were previously stored in Building 819. The removal of these and other hazardous substances by the Navy are described in the report in Appendix
CERCLA IR Sites: There are no Superfund Installation Restoration (IR) Sites in Parcel UC-1 but part of IR Site 6 underlies Parcel UC-2. Low concentrations of the solvents chloroform and carbon tetrachloride have been found in groundwater in IR Site 6. The remedy selected in the Record of Decision (ROD) for these chemicals was natural attenuation and institutional controls. Basewide issues of radiologically contaminated storm drain and sewer lines, steam lines, and electrical equipment affected the parcels. Steamlines were investigated and found not to contain waste oil so further investigation was not required. Storm drains and sewer lines were excavated to remove any radiological hazard. The electrical transformer and substation that might have contained PCB was removed.
Pesticides: The property may contain residues of pesticides that were applied to manage the property before transfer. There is no evidence that pesticides had been applied inappropriately or contrary to the labeling on their packages. The Navy's position is that it has no responsibility to remediate legally applied pesticides.
Radiological Materials: The Navy's Historical Radiological Assessment (NAVSEA 2004) described Building 819 as potentially radiologically impacted. The building was surveyed and found to present no unacceptable radiological risks. Storm and sewer drains potentially impacted have been removed and surveyed. Final clearance for unrestricted use by the California Department of Health is pending.
Lead-Based Paint: Any buildings built before 1978 are assumed to contain lead-‐based paint which was in common use up to that time. The Navy did not survey Buildings 819 and 823 for LBP because the buildings were not intended for residential use. The buildings are assumed to contain LBP so demolition or re-‐use as residential by the new owners must comply with applicable LBP regulations.
Asbestos-Containing Material: The basewide environmental baseline survey detected asbestos in Building 823 but not in Building 819. This asbestos will be the responsibility of the new owner.
Storage Tanks and Pipelines: There is no record of above ground or underground storage tanks at Parcels UC-1 or UC-2. Natural gas lines run through both parcels. No other petroleum lines run through Parcels UC-1 and UC-2.
Polychlorinated bi-phenyls: These long-‐lasting substances, abbreviated PCB, are now known to be toxic and to accumulate in the food chain. They were formerly used widely in oils and electrical equipment such as transformers. The Navy or former tenants at HPS have addressed all PCB issues there by decontamination or removal.
Groundwater: Groundwater generally flows onto Parcels UC-1 and UC-2 from uncontaminated areas and down gradient from the parcels towards contaminated areas. Possible vapor inhalation risks from chemicals in the groundwater are addressed by restrictions on use of the land by the new property owners. These restrictions are described in the Institutional Control (IC) section below.
CERCLA Institutional Controls: Institutional controls, land use restrictions, will be implemented for soil and groundwater at Parcels UC-‐1 and UC-‐2. The main provisions of these restrictions are the following. (1) Growing anything for human consumption or using groundwater will be prohibited. (2)
These activities will be prohibited without prior approval from the Navy, U.S. EPA, and State of California: a residence, a hospital, a school for those under age 21 years, a daycare facility for children, land disturbing activities, anything that facilitates movement of contaminated groundwater, removal or modification to any component of the remedy or security features, and construction of any enclosed structure. A risk management plan will describe the activities and procedures for permitting certain restricted activities without prior permission of the Navy, EPA, and State.
Inspections and Compliance with Land Use Restrictions: There will be annual inspections and compliance reports. These reports will continue until a 5-‐year review determines that the controls are no longer needed. For example, if the groundwater contamination declines over time, then the areas needing institutional control to prevent risk from vapor inhalation could decrease. The exact process and responsible parties for inspections have not been decided yet. One possibility would be for homeowner associations to self-‐certify compliance and to have the SFRA perform an annual inspection to verify it and report to the Navy, EPA, and State of California.
Potential Issues for Community Concern:
(1) the draft report does not contain the Remedial Action Completion Report that will be needed before the FOST is finalized, (2) the durable cover remedy is not described in detail nor is the required monitoring of the cover and groundwater and maintenance of monitoring wells. (3) Ongoing soil gas surveys are not yet complete. The public and regulatory agencies will not be able to review these until the final FOST unless a revised draft is issued.
