- 1963-2002
- Limitations
- Corrects the era for this distinct tug only. It does not transfer any history or material evidence from the later USNS Apalachicola (T-EPF-13) mentioned in the same release, and says nothing about asbestos.

[3]U.S. GAO, Navy Efforts To Protect Workers From Asbestos Exposure, HRD-80-2 (1979), enclosure I: Chief of Naval Operations letter of 1979-01-05 and attachment 1 [gao]

- PDF pp. 11, 21 (Navy letter and large harbor tug table; printed enclosure pp. 1, 11)
- Finding type
- historical_record
- Finding
- A 1979 Navy letter reproduced by GAO says Navy ships in service then contained some asbestos. Its attached table identifies asbestos thermal insulation in large harbor tugs YTB-817 through YTB-831 delivered in 1973-74; YTB-832 and later listed tugs are shown with asbestos-free thermal insulation. The table does not list YTB-767.

- Navy ships and naval shipyard workers generally
- Limitations
- The listed YTB-817-and-later vessels are different hulls built roughly a decade after YTB-767. The Navy's fleet-wide wording cannot be converted into a ship-specific material finding for Apalachicola. The table provides no quantity, location, condition, maintenance event, or exposure evidence for YTB-767.

[4]Naval Sea Systems Command, FOIA Reading Room, Asbestos: QPL-15091-5 and QPL-15342-(1-12) index entries [other_primary]

- Asbestos Related Files table, QPL-15091-5 and QPL-15342-(1-12)
- Finding type
- historical_record
- Finding
- NAVSEA's asbestos reading-room index lists a qualified-products record for asbestos-fiber thermal insulation felt dated 1962 and metallic-asbestos spiral-wound boiler gaskets dated 1961-74. These show Navy material specifications current near the tug's launch period, without identifying YTB-767 or its fittings.

- Finding
- No publicly accessible ship-specific asbestos survey, abatement record, or material specification naming YTB-767 was located in the official sources searched for this batch. Authenticated CourtListener exact-name and hull-number opinion and docket searches returned no results.

- The negative finding is bounded by the listed public sources. NARA drawings were indexed but not retrieved. No results in the four CourtListener searches do not prove that no case exists outside its searchable records, nor that asbestos was absent.
