- Finding
- Documented naval-shipyard availability for this hull: under repair at Navy Yard Mare Island, Vallejo CA, 23 June-20 August 1945, corroborated by three official Navy Yard Mare Island photographs (14 and 17 August 1945) showing the ship off Mare Island and aft of USS LST-478 at the yard. This is the most asbestos-relevant ship-specific event located: a wartime repair availability at a naval shipyard inside that yard's documented asbestos-use era (Mare Island is a tier-2 Atlas shipyard record with documented ACM product usage). The repair work packages themselves (RG 181 Mare Island records / ship's action reports) were not located - presence and window are documented, scope of work is not.

- LST-487 crew during availability; Mare Island Naval Shipyard trades working the hull (Jun-Aug 1945)
- Limitations
- Establishes presence and a repair window at the yard, not what work was performed - a yard availability is not proof that asbestos materials aboard were disturbed or installed, and no work package, item list, or hazmat record for this availability was located. Mare Island yard-level asbestos documentation is a shipyard-dataset record, not hull evidence. No asbestos content in the photographs or captions.

[6]Era/design inference consolidated from: NavSource specifications (two GM 12-567A diesels, Falk reduction gear, three diesel-drive generators - diesel plant, no boilers); BuShips Ships' Data 1945 Vol. 2 LST design data (per lst-1-class class profile ev-01); WWII amphibious-ship construction practice [other_primary]

- Finding type
- asbestos_application
- Finding
- A diesel-powered LST-1-class tank landing ship built at a Kaiser Richmond yard in early 1943 sits inside the documented WWII shipbuilding asbestos era. For this diesel type (no boilers) the era-standard asbestos-relevant applications were: GM diesel exhaust lagging and gaskets, engine-room thermal and acoustic insulation, deck coverings/tile, bulkhead and accommodation insulation, winch/crane brake linings, and valve/flange gaskets and packing. The boiler/turbine steam-lagging pathway of steam vessels does not apply, but the confined-volume crew exposure dynamic does.

[7]NIOSH record (CDC Stacks): Polakoff, P.L., 'Bay Area Asbestos Surveillance Project (BAASP)' (1980) - screening of WWII-era San Francisco Bay Area shipyard and longshore workers [other_primary]

- Finding type
- gov_survey
- Finding
- Government documentation of asbestos exposure in this hull's builder population: the NIOSH-indexed Bay Area Asbestos Surveillance Project screened San Francisco Bay Area workers who had worked in shipyards during WWII (including women shipyard workers) and longshore/shipyard workers with self-reported asbestos exposure before 1963. Of 2,244 workers x-rayed, 46% showed potentially serious radiographic abnormality and 30% questionable abnormality. Kaiser Richmond (this hull's builder) operated four WWII shipyards inside that Bay Area population.

- Limitations
- Regional population documentation, not a yard or hull record: the NIOSH abstract does not name Kaiser Richmond or LST-487; it establishes the exposure context for WWII Bay Area shipyard labor generally. Does not establish materials aboard this hull, individual exposure, or any claims eligibility.

- Finding type
- gov_survey
- Finding
- GAO reviewed the Navy's asbestos-protection program (fieldwork at Long Beach and Norfolk Naval Shipyards): the Navy used asbestos insulation extensively aboard ships and did not begin substituting alternative insulation until the early 1970s; 1975 policy removed asbestos insulation only when damaged or needed for repairs, modified 1979 to selective replacement in high-maintenance areas. Navy-wide program context spanning this hull's 1943 construction era.

- Program-level documentation; supports era context only, not any fact specific to this hull - and the program-era policies (1975/1979) postdate LST-487's 1948 sale, so the 'insulation remained for decades' dynamic does not apply to this hull.

- Finding
- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, material schedule, hazmat disclosure, or verified litigation naming USS LST-487 was found in the public sources searched (see search_ledger). CourtListener exact-phrase searches returned zero opinion and zero docket hits for '"LST-487"' and zero opinion hits for '"LST 487"' (an unquoted LST-487 opinion query returned 120 tokenized noise hits, none referencing the vessel); two remaining variant queries were throttled by fleet pacing and are logged as blocked, not negative. Secondary web sweeps surfaced no qualifying case; the only asbestos material naming the type is law-firm marketing content (Gori Law 'Asbestos on Landing Ships' class page; navyshipexposure.com LST class page; asbestoscalifornia.com Kaiser Richmond yard page) - class-level marketing excluded by source policy; none names this hull.

- Limitations
- Absence of a located public record does not prove absence of asbestos aboard - a 1943 Kaiser-built hull is era-consistent with asbestos-containing construction materials. The litigation-repository search has partial coverage only (two variant queries blocked by fleet pacing). NARA deck logs (RG 24), the Mare Island repair work package (RG 181), and the Brown & Root merchant-conversion record are undigitized leads. Does not establish or defeat any claim of exposure or legal eligibility.
