[4]Shipbuilding History (Colton), Albina Engine & Machine Works yard table, hull no. 51 = PC 569 (284 gt, 174 ft, delivered 8 May 1942); WWII sub-chaser build table confirms builder and dates [other_primary]

- Finding
- Colton's yard table lists Albina hull no. 51 as 'PC 569, U.S. Navy, Sub Chaser, 284 gt, 174 ft, delivered 8-May-42; Named Petosky [sic] 1956, sold 1960.' The yard history records Albina Engine & Machine Works founded 1904 by William Cornfoot, a WWI-era cargo-ship builder that specialized in subchasers during WWII; sold to Dillingham Corp. circa 1971; the original Albina yard closed when Dillingham liquidated in 1986 and the ship repair division became Cascade General at Swan Island (assets sold 1987).

- asbestos_application
- Finding
- A steel-hulled patrol craft built 1941-42 and fitted out at a naval shipyard sits inside the documented asbestos-use era of U.S. naval shipbuilding; GAO documented Navy-wide asbestos insulation use through the early 1970s. Era-standard applications aboard a vessel of this type and period were machinery and diesel-exhaust lagging, thermal insulation in engine spaces, gaskets, valve packing, electrical insulation, deck coverings, bulkhead insulation, and adhesives/cements. Because PC-461 class boats were diesel-propelled with no steam plant, the boiler/steam-line lagging pathway of steam vessels does not apply.

- Finding
- GAO documented that the Navy used asbestos insulation extensively aboard ships and did not begin substituting alternative insulation materials until the early 1970s - spanning this hull's entire construction (1941-42) and service era (1942-47) and reserve-fleet custody (1947-60).

- Finding
- The builder yard's former site is inside the EPA Portland Harbor Superfund remedial-investigation study area. The RI tables identify the 'Former Albina Engine and Machine Works Shipyard' (shipbuilding/ship repair, river mile 8-9) and log historical releases: a 1971 oil slick reported at the shipyard, and a 1975 Oregon DEQ observation of fugitive emissions from Albina sandblasting operations with uncontrolled material storage/handling - DEQ instructed Albina to cease sandblasting. Related ECSI site #5117 ('former shipyard and machine works property') lists primary contaminants PCBs, TPH, metals, and PAHs.

- Finding
- The vessel name 'USS Petoskey' appears in indexed CourtListener docket text for the W.R. Grace Chapter 11 asbestos bankruptcy (Bankr. D. Del. 01-01139). The Grace bankruptcy administered tens of thousands of asbestos personal-injury claims; the token's presence in docket text is consistent with a claimant-filed exposure listing naming this hull, but the specific docket entry or document where the name appears is not retrievable via the public search index and was not retrieved this session.

Whether the token names this vessel (vs. a person or place 'Petoskey') is unverified from the index; the 'USS' prefix makes the vessel the probable referent.

CourtListener base queries completed: 'USS Petoskey' opinion search returned 0 results; 'PC-569' opinion search returned 2 name-collision hits (Indiana post-conviction docket number; token in an unrelated Sixth Circuit case); 'PC-569' docket search returned 17 name-collision hits; 'USS Petoskey' docket search returned 1 hit - the W.R. Grace asbestos bankruptcy docket, a claim-level reference logged as archival lead ev-09. The hull was sold out of Navy custody in 1960 to a private buyer and her final fate is unknown - no museum, memorial, or surviving-hull documentation exists to hold an ACM record.

- Absence of a located public record does not prove absence of asbestos aboard - a 1941-42 naval vessel of this type sits inside the documented era of asbestos use in U.S. naval shipbuilding. Deck logs (NARA College Park, RG 24 series 594258), BuShips construction records, and disposal/sale-contract files are undigitized leads. Does not establish or defeat any claim of exposure or legal eligibility.
