- Finding type
- asbestos_application
- Finding
- The Wind-class design documentation records the class's insulation and propulsion materials: hulls carried compressed cork insulation, and propulsion was diesel-electric - six Fairbanks-Morse 10-cylinder 2-cycle diesels driving six Westinghouse generators feeding two Westinghouse electric motors on twin shafts (5,000 SHP per the 1966 spec block), with a detachable bow propeller and rapid-transfer heeling tanks (220 tons of water shifted in ~90 seconds inducing a 10-degree list). There is no boiler or steam plant on this class.

- Limitations
- Class-level design documentation, not a hull survey: establishes the documented thermal insulation was cork and the plant diesel-electric - bounding but not eliminating the asbestos era-inference. Gaskets, packing, electrical insulation, floor coverings, and other era-typical ACMs are not addressed by this source. Does not establish presence or absence of asbestos aboard this hull.

[4]U.S. Coast Guard, ALCOAST 364/17 (COMDTNOTE 6010, Dec 2017) 'Medical Documentation of Asbestos and Lead Exposures on Coast Guard Cutters' + CG-112 veteran guidance + official list 'Coast Guard Cutters Constructed Prior to 1991 and In Service from 1990 to 2017' (list verified: 'EDISTO - WPB-1313' only; WAGB-284 absent) [other_primary]

- Finding type
- regulatory
- Finding
- Official USCG guidance states that Coast Guard cutters constructed prior to 1991 'are known to have asbestos materials (asbestos-containing thermal insulating material and/or asbestos-containing floor tiles)' and that routine exposures occurred for members who worked on and berthed in them, with exceptional exposure during maintenance such as tearing up asbestos-containing floor tile; ALCOAST 364/17 directed medical documentation for members assigned to such cutters. The accompanying official cutter list is scoped to cutters in service 1990-2017 and does not name this hull - its sole 'Edisto' entry is WPB-1313, the later Island-class patrol boat - because this vessel decommissioned in 1974.

- Population
- USCG cutter crews (service-wide policy population)
- Limitations
- Fleet-level policy statement, not a hull record: the 'constructed prior to 1991' criterion covers this 1946-built hull but the name list's in-service window (1990-2017) postdates her 1974 decommissioning, so no per-hull ACM finding exists. USCG characterizes routine levels as 'very low' and below the Medical Surveillance Action Level / OSHA levels. Does not establish asbestos presence aboard this hull, quantity, location, condition, or any individual exposure.

- Finding
- Peer-reviewed historical study documents that asbestos was used extensively as a fireproofing and insulating material in U.S. shipbuilding during WWII - the era of this vessel's authorization (Dec 1943) and construction (keel 1945, launch 1946, commission 1947) at a yard building Navy/Coast Guard combatant and auxiliary hulls under wartime-era specifications.

- Limitations
- Program/era-level scholarship; does not name this vessel or this yard's output specifically. Does not establish that asbestos was or remains aboard this hull - and the hull's documented diesel-electric plant and cork hull insulation reduce the steam-era inference relative to combatant types. No quantity, location, condition, exposure, or causation established.

- Finding
- Documented construction/maintenance events on this hull: built at Western Pipe & Steel, San Pedro (1945-47); overhaul at Boston Naval Shipyard during the 1963-64 season in lieu of that year's Antarctic deployment; winter 1965-66 repairs and alterations at 'the Bethlehem Steel Shipyard' including a new flight deck with telescopic hangar; towed into the Coast Guard Yard (Curtis Bay), Baltimore, arriving 30 Nov 1971 for repairs after the Mizar incident propeller/rudder damage; decommissioned there 15 Nov 1974; dismantled at Baltimore after the 1977 GSA sale to Boston Metals/Union Minerals.

- Limitations
- Documents yard periods only; no asbestos scope, abatement record, or material inventory is documented for any of them - the maintenance-disturbance pathway exists but its asbestos scope is inference. The 1965-66 source says only 'Bethlehem Steel Shipyard' without a city (Boston-area Bethlehem facilities - Fore River/Quincy or Atlantic Works/East Boston - are likely but unconfirmed). Hull was scrapped before modern NESHAP/shipbreaking documentation regimes.

- Finding
- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, or litigation naming USS Edisto (AG-89/AGB-2) or USCGC Edisto (WAGB-284) was found in the public sources searched. The official USCG pre-1991 ACM cutter list does not name this hull. CourtListener's API was rate-limited (125/day cap already exhausted; ~11 h reset) during this session - the direct docket-level name search could not be completed; an indirect web-index check (site:courtlistener.com Edisto) returned only South Carolina geographic name collisions (Edisto Recycling demurrage, Edisto Island property/auto-injury, zoning) - all classified non-qualifying (see search_ledger).

- Limitations
- Absence of a located public record does not prove absence of asbestos aboard. A 1945-47 diesel-electric hull documented with cork hull insulation presents a weaker era inference than steam-plant vessels, but era-consistent ACMs (gaskets, packing, floor tile, electrical insulation) cannot be excluded. Does not establish presence or absence and neither establishes nor defeats any exposure claim or legal eligibility. The CourtListener docket-level search remains an open gap.
