[4]Complaint for Personal Injury; Exhibit A; and Demand for Jury Trial, Jacob v. Plastics Engineering Company (PLENCO) et al., No. 1:19-cv-00108 (D. Guam filed 2019-06-20; terminated 2020-02-26) (RECAP docket 15808518, document 1) [court_record]

- Complaint paras. 4-6 (plaintiff employment and ship-board allegation); Exhibit A row 34 (LST-1122, 4/24/1963-7/5/1963, 'Apra Harbor, Guam'); PDF pp. 2-3, 9-13 of 13
- Finding type
- litigation_documented
- Finding
- Docketed asbestos personal-injury action (suit nature '368 P.I.: Asbestos'; diversity). Complaint alleges plaintiff Eusebio V. Jacob, a journeyman electrician at the Guam Navy Ship Repair Facility approximately 1962-1985, 'worked in and on ships where the said asbestos products were being used,' was repeatedly exposed to asbestos dust/fibers, and was diagnosed with mesothelioma (August 2018, Hawaii Pathologists' Laboratory). Exhibit A ('Guam Naval Repair Facility Deck Log Rule 1006 Summary') lists USS San Joaquin County (LST-1122) at 'Apra Harbor, Guam,' 24 April-5 July 1963, among ~40 ships the complaint places in plaintiff's work environment; the complaint also alleges defendants sold OEM asbestos gaskets and packing to Guam SRF installed in equipment aboard the Exhibit A ships.

- Population
- Guam SRF journeyman electrician, ~1962-1985; mesothelioma (alleged)
- Limitations
- Pleading-stage allegation, not an adjudicated finding: the vessel list is an allegation and the deck-log-derived exhibit itself flags that San Joaquin County's entries 'only name Apra Harbor, Guam' (not the Ship Repair Facility proper). Does not establish that asbestos was aboard this hull, that plaintiff worked on this hull specifically, or any exposure/causation. RECAP contains only the complaint; the case terminated 2020-02-26 but the disposition (settlement vs. dismissal vs. judgment) is not in the public file reviewed.

LST-1122 falls in the LST1081-1152 design block built at Chicago Bridge & Iron, Seneca - a diesel plant with no boilers.

[6]Era/design inference for diesel-powered LST-542-class hulls (per BuShips SDB-1945 v2 plant description + WWII-era Navy material practice) [other_primary]

- SDB-1945 v2 LST design table (propulsion plant); era materials practice
- Finding type
- asbestos_application
- Finding
- Era-consistent inference only: with no boilers, the asbestos-relevant applications aboard an LST-542-class ship concentrate in diesel engine and exhaust lagging, machinery gaskets and valve packing, engine-room thermal/acoustic insulation, deck coverings and tile, bulkhead and accommodation insulation, and winch/windlass brake linings - insulation and friction/gasket products of the period were commonly manufactured with asbestos fiber.

- Limitations
- Design-era inference, not a ship record: no material schedule, specification, survey, or ship-specific document establishes asbestos products aboard this hull; asbestos presence is inferred from era practice, not proven for LST-1122. Does not establish quantity, location, present-day relevance (hull scrapped 1974), or any individual exposure.

- Finding type

- Finding
- The VA ship list's Category I ('ships operating primarily or exclusively on Vietnam's inland waterways') includes the blanket designation entry 'All vessels with the designation LST [Landing Ship, Tank]' for Agent Orange herbicide-exposure presumption purposes under 38 CFR 3.307(a)(6)(iii). San Joaquin County is not individually named; her type is covered at designation level. DANFS documents her Vietnam service (Jan-Feb 1967) as offshore support at Danang/Quang Ngai.

- Vietnam-era LST crew members (herbicide presumption class)
- Limitations
- Herbicide (Agent Orange) adjudication record, not an asbestos record - included as veteran-population context only. The blanket entry covers the LST designation; it does not establish that this hull operated on inland waterways (DANFS describes offshore operations), and it establishes no asbestos fact. VA's canonical page for the list has moved; cited copy is a VSO-organization mirror of the VA Compensation Service document (PDF creation date 2014-09-03); the 2021 edition (vfwfl.org mirror) contains the identical LST designation line.

- NARA holds digitized primary records for this hull: four WWII war-diary file units (September, October, November, December 1945 - the occupation-service period) and a run of monthly deck logs spanning at least 1956-1969, scanned in the RG 24 'VA_Batch' series with BWN (Blue Water Navy) batch filenames indicating the Agent-Orange-era digitization project.

[9]GAO HRD-80-2, report on Navy asbestos hazards / asbestos-protection program (product page) [gao]
- Locator
- GAO product page HRD-80-2 (blocked to automated fetch; description-level)
- Finding type
- gov_survey
- Finding
- GAO documented the Navy's asbestos-protection program: standing policy (1975) removed asbestos insulation only when damaged or required for repairs, modified 1979 to selective replacement in high-maintenance areas - meaning original-era insulation typically remained in place for decades unless a yard period disturbed it. Program-level context for a ship scrapped in 1974.

- No qualifying ship-specific asbestos record was located beyond the pleading-stage Jacob complaint: no asbestos survey, abatement contract, museum hazmat disclosure, or adjudicated opinion names this hull. CourtListener exact-hull opinion search returned zero hits; 'San Joaquin County' + asbestos opinion hits are all California-county name collisions. Law-firm/marketing ship-list pages that assert asbestos aboard LSTs were excluded by source policy.

- Limitations
- Absence of a located public record does not prove absence of asbestos aboard - a pleading allegation names the hull and the era/design is consistent with retained ACM; the hull was scrapped in 1974 (pre-regulation era), so no present-day remediation record is expected. Does not establish or defeat any claim of exposure or legal eligibility.
