[1]McAllister v. McDermott, Inc. et al., No. 3:18-cv-00361-SDD-RLB (M.D. La.), Ruling on Defendants' Motions for Summary Judgment, Rec. Doc. 357 (filed 2020-08-14, Chief Judge Shelly D. Dick) [court_record]

- Finding
- Published federal summary-judgment ruling recites discovery-stage record naming this hull: James T. McAllister served aboard TRITON October 1966 to late 1968/early 1969 as a machinist mate working in the engine rooms; he testified he worked with and around asbestos-containing gaskets, packing, and insulation maintaining valves, pumps, and steam traps, cut custom asbestos gaskets from sheet, scraped deteriorated gasket material from flanges (10-30 minutes per flange), pulled packing and blew out packing glands with an air hose creating 'dust all over the place,' performed this work 'hundreds and hundreds' of times, and worked on TRITON's decommissioning (draining systems, repairing pumps and valves). Aboard TRITON and STURGEON he identified Garlock, Cranite, and Durabla gaskets. Buffalo Pumps' corporate records (per rep. Martin Kraft) evidenced sale of two turbine-generator condensate pumps as original equipment plus onboard spares for TRITON, and that those pumps used asbestos-containing gaskets and packing delivered to the Navy with asbestos components installed; plaintiffs' naval expert Capt. Arnold Moore confirmed a Buffalo condensate pump sold for TRITON and documented four Edward valves in TRITON's engine room. Disposition: summary judgment GRANTED to Tate Andale (successor-liability grounds only - non-exposure) and to Velan Valve (no Velan product identified aboard); DENIED to Spirax Sarco, Air & Liquid/Buffalo, and Flowserve - genuine fact disputes held for jury. No court found that exposure occurred; the opinion recites testimony and records at the summary-judgment stage.

- Limitations
- Discovery-stage record recited in a summary-judgment ruling - not an adjudicated finding that McAllister (or anyone) was exposed aboard TRITON. Denied motions establish triable disputes, not facts; granted motions disposed of defendants on successor-liability (Tate Andale) and product-identification (Velan) grounds, not on findings that TRITON lacked asbestos. McAllister's window aboard (1966-69) coincides with documented inactivation period (Oct 1968-May 1969). Post-August-2020 disposition (settlement, trial, dismissal) not located - RECAP/CourtListener unavailable this session (throttled).

- Finding
- Official Navy disposal record names this hull: Appendix D lists reactor-compartment shipments No. 119 ('Ex-Triton, Plant #1') and No. 120 ('Ex-Triton, Plant #2'), SSN 586, with YEAR RC DISPOSAL COMPLETED 2009 and YEAR SHIP RECYCLE COMPLETED 2009. Triton's two reactor compartments were shipped to the DOE Hanford Site for trench disposal and the remainder of the ship recycled at Puget Sound Naval Shipyard in 2009 - the only U.S. submarine with two reactor plants, hence two RC packages.

- Finding type
- abatement_record
- Finding
- Program-level Navy documentation covering the process Triton demonstrably underwent (per Appendix D, ev-03): 'one of the first actions when a ship begins the recycling process is to identify and tag equipment and structure that contain [asbestos, PCBs, metallic lead]. This includes shipboard sampling to identify insulating materials (both on piping systems and on ship's structure), paint, and other products that may contain asbestos or PCBs.' 'Asbestos insulation is removed by personnel specially trained in asbestos work under stringent work controls' with containments, HEPA vacuums, wetting agents, air monitoring, and landfill disposal. 'Reactor compartments constructed before the mid-1970s also contain asbestos in insulation on pipes and other components. This asbestos is fully contained within the reactor compartments' shipped to Hanford - TRITON's plant was built 1956-59 and both its RCs shipped to Hanford in 2009, so on the Navy's own program statement its RC packages contained asbestos insulation.

- Limitations
- Program-level process description, not a Triton-specific survey or manifest - the asbestos passages do not name this hull; the linkage is that Appendix D (same document) documents Triton's recycling under this program, and the RC-asbestos statement covers all pre-mid-1970s compartments including Triton's. No quantity, no itemization for this hull. Does not establish individual exposure outcomes during recycling.

- Finding type
- asbestos_application
- Finding
- A twin-reactor submarine built 1956-59 at Electric Boat and converted at Portsmouth Naval Shipyard 1962-64 sits inside the Navy's peak asbestos-use era; era-standard applications on the secondary steam plant (steam generators to turbines) and auxiliary systems included thermal/pipe insulation and lagging, gaskets, packing, machinery insulation, and insulation in habitability spaces. Both yards' asbestos product use in this period is independently documented at the yard level, and litigation discovery (ev-01) corroborates asbestos gaskets/packing/insulation in this hull's engine-room systems.

- NPS documents that from 2007 to 2009 Triton was dismantled and recycled in Bremerton, WA, and that the Port of Benton acquired the sail during that process and installed it in 2011 at the USS Triton Sail Park, Richland WA - the site overlooks the Port barge slip where Navy reactor compartments (including Triton's) come ashore for transfer to the Hanford Site. Port of Benton confirms the dedication was held 10 November 2011, the 52nd anniversary of Triton's commissioning; a veterans' commemorative wall was added 14 June 2025. The sail interior (conning tower, original instruments) is open for scheduled tours.

- Finding
- CORRECTIONS vs secondary sources: (1) Sponsor - Wikipedia's infobox lists 'Willis A. Lent,' but DANFS states the launch sponsor was Mrs. John Will; Lent was commanding officer of the earlier Triton (SS-201, 1940-42), later an Electric Boat employee, and died 28 August 1959 - a probable conflation. (2) Complement - DANFS lists 159; the Operation Sandblast voyage carried a larger party (USNI: 16 officers, 34 petty officers, 125 enlisted = 175, plus a psychiatrist and a National Geographic photographer; an unverified 188-name crew list circulates on a Wikipedia user subpage). The voyage-party size is not the complement. (3) Class - hullnumber.com labels Triton 'Skipjack-class'; she was a unique, single-unit class (DANFS 'class Triton').

CourtListener opinion/docket search was attempted for 'USS Triton,' 'SSN-586,' and 'SSRN-586' and was unavailable this session (API HTTP 429, daily quota exhausted, ~12h backoff; web UI HTTP 403) - logged as blocked, not as 'no result.' A general-web litigation sweep located one qualifying asbestos matter naming this hull (McAllister, ev-01); law-firm vessel pages asserting Triton asbestos products trace to that deposition and were excluded as sources. Competitor claims of 'excessive amounts of asbestos' aboard Triton and '~60,000 lbs of asbestos per submarine' could not be traced to a primary source and are excluded.
