Work Plan, PFAS Site Inspection Naval Computer and Telecommunications Station Stockton, California Background Information 2-4 DCN: TRBW-0202-5183-0010 In November 1969, a military specification was issued that described characteristics that AFFF needed to demonstrate to be used by the military, including a requirement for formulations containing PFAS. The Navy has used AFFF-containing PFAS in fire training exercises, in suppression of aircraft and other vehicle fires, and in aircraft hangar fire suppression systems at many of its installations across the U.S. The potential release mechanisms of PFAS to the environment at Navy facilities include AFFF use as part of the following activities: fire training exercises at burn pits or structures; crash crew training exercises; hangar fire suppression system operations, testing, and accidental releases; firefighting and crash response vehicle testing; emergency response actions, such as at aircraft and vehicle crash sites; responses to Class B or fuel fires; and improper filling and leakage from storage tanks, firefighting trucks, or crash response vehicles. Despite the industry efforts to reduce the use of PFAS, some PFAS are still required as an integral component of AFFF by the current military specification. The Navy is the lead agency with environmental regulatory oversight provided by the DTSC and the Water Board. This current project is administered through NAVFAC SW. Other stakeholders include the Port of Stockton, who acquired the property from the Navy in 2003 and currently manages port and maritime activities at RRI. 2.4 Historical Setting The following provides a brief historical description of the former NCTS Stockton facility and the use of AFFF. 2.4.1 Facility History and Past Site Use During Navy operation of RRI, NCTS Stockton occupied all but three parcels located in the northeastern portion of the island, which were owned by oil companies and a developer. Beginning in July 2000, the Navy transferred properties to the Port of Stockton through the U.S. Department of Transportation Maritime Administration (MARAD) in four phases. The Phase I property transfer utilized a Finding of Suitability to Transfer (FOST) that conveyed to the Port 89 parcels covering approximately 496 acres and leased 69 parcels. The Phase II property transfer utilized a separate FOST that conveyed to the Port 33 of the 69 leased parcels covering about 412 acres. All environmental concerns associated with parcels conveyed in Phases I and II had received a “no further action” status from DTSC and the Water Board. A Phase III Finding of Suitability for Early Transfer (FOSET) transferred the remaining 36 parcels to the Port of Stockton in September 2003. The Phase IV property transfer, which included a remaining 60-acre parcel, was transferred in 2010. RRI was conveyed by the Navy to the Port in accordance with the Final Rule for Public Benefit Conveyances of Port Facilities (PBC; 60 Federal Register 35706, Subpart 101‐47.3, Section 101‐ 47.303‐2, 11 July 1995) through MARAD, the sponsoring agency. The PBC required the
