  3. [3]IN RE Asbestos Products Liability Litigation (No. VI), MDL-875 (JPML), ECF No. 8536 Att. 2 — Robert McKinley Jr. complaint (filed Mar 20, 2012); document text verified [court_record]

    Finding
    PLEADING-STAGE allegation, document-verified: the McKinley complaint alleges the plaintiff worked aboard a multi-submarine vessel list including 'USS Portsmouth' (alongside USS Los Angeles, USS La Jolla, USS Salt Lake City and numerous other hulls) and was exposed to asbestos and asbestos-containing products during that work.

    Limitations
    Pleading-stage allegation only — a boilerplate MDL-875 complaint's vessel list is an allegation, not an adjudicated finding. The list's breadth (dozens of hulls) is itself a limitation: it does not establish which specific vessel(s), if any, involved actual exposure, nor which Portsmouth namesake is meant (this hull vs CL-102 — the plaintiff's service era determines this and was not extracted). No causation, no quantity, no ACM confirmation, no eligibility.

    Finding
    Index-verified asbestos-litigation matches with undetermined namesake: two Puget Sound plaintiff-family suits match 'USS Portsmouth' — Yoder v. CBS and Holck v. Carrier (both W.D. Wash. 2014). The namesake could be THIS hull (recycled at PSNS after 2005 — plaintiffs who worked the recycling program could have encountered her), the WWII-era USS Portsmouth (CL-102, scrapped 1974), or Portsmouth Naval Shipyard itself; document texts were not retrievable this session (rate-limiting). W.R. Grace & Co. (Bankr. D. Del. 2006) also matched — context unverified.

    Limitations
    UNVERIFIED at document level — namesake identity undetermined in each match; carried as archival leads only. If verified as this hull, each would be a pleading-stage allegation at most — not a finding of exposure or asbestos aboard. The verified McCrossin collision (below) shows the W.D. Wash. 'USS Portsmouth' string is ambiguous.

    Finding
    Verified name collision, not qualifying litigation for SSN-707: McCrossin's 'USS Portsmouth' references are (1) a 1972 Navy document 'Protection of Workers During Removal Operation in USS Portsmouth' — the WWII-era light cruiser CL-102, scrapped 1974, a decade before this hull's 1982 launch — and (2) Portsmouth Naval Shipyard itself. Not evidence about SSN-707.

    Finding type
    asbestos_application
    Finding
    A Flight I Los Angeles-class submarine built 1980-83 at Electric Boat sits at the tail of the Navy's peak asbestos-use era: GAO documented the Navy began substituting alternative insulation materials in the early 1970s, while asbestos-containing gaskets, packing, and residual insulation products persisted in shipboard applications into the 1980s. This hull's build, its February 1991 Mare Island Depot Modernization Period, and its post-2005 PSNS recycling are the asbestos-relevant yard windows — residual asbestos applications and disturbance were era-plausible but are undocumented for this hull; nuclear propulsion itself establishes nothing.

    Class/era inference only — weaker than for pre-1970 hulls because construction post-dates the Navy's documented substitution start. No hull-specific insulation survey or material list located for SSN-707. Names era-possible applications and documented yard windows, not confirmed installed materials or disturbance; no quantity. Does not establish exposure.
