- NavSource is a volunteer-compiled photo/history archive, not an official record - treated here as the organizing secondary source because official sources (DANFS, NVR) carry no narrative for this hull. Sinking date given as 12 April 2007; other compilations give 11 April (the SINKEX began 11 Apr and the sinking exceeded 12 hours - see ev-08 and gaps).

- Limitations
- Documents the host vessel, not this craft - La Salle's own asbestos posture is a separate hull record (uss-la-salle-agf3, tier 2 class/era inference) and none of it is imported here. The co-location matters only because IX-519 was welded inside La Salle's well deck and its occupants were La Salle/Sixth Fleet personnel. NavSource/DANFS are compiled/official narrative records; neither mentions IX-519 by name (the NavSource IX-519 page provides the welding fact; DANFS entry predates the conversion). No asbestos information about either hull.

MarineLink trade coverage reports Orange completed a 26-unit YC contract for the Navy in 1993 with a further 22 YCs and two double-skin YON fuel barges underway - placing this craft inside the post-1980s small service-craft procurement that Shipscribe characterizes as rare ('only eight new service craft, excluding tugs, were built between 1980 and 2025' on the self-propelled side; non-propelled lighter procurement was similarly limited).

[9]GAO, Navy Efforts To Protect Workers From Asbestos Exposure, HRD-80-2 (Oct 18, 1979) - program-level boundary document for the Navy's asbestos-use era, which predates this craft's 1991 construction [gao]

- Finding type
- asbestos_application
- Finding
- Era-boundary context only: GAO's 1979 review documents the Navy's peak asbestos-use period and the worker-protection program that era produced - a period that closed well before this craft was built (1991) and converted (1994). The standard steam-era exposure pattern is doubly inapplicable here: the hull postdates the documented peak-use era, and as a non-self-propelled open lighter it had no boilers, turbines, engines, or steam piping at all. Any asbestos aboard would derive only from early-1990s conversion materials (interior deck coverings, joiner bulkheads, HVAC insulation), whose specification is undocumented.

GAO report covers shipyard-worker protection through 1979, not craft composition. Does not establish asbestos was absent or present aboard.

- Finding
- The craft's 2007 sinking aboard ex-La Salle occurred under the EPA's MPRSA general permit for SINKEX target vessels (40 C.F.R. 229.2, issued 1977): preparation requires removal 'to the maximum extent practicable' of all materials that may degrade the marine environment - emptying/flushing fuel tanks and lines essentially free of petroleum and removing other pollutants and all readily detachable debris; sinkings must occur at least 50 nautical miles from land in at least 6,000 feet of water. The permit regime's documented hazmat scope is petroleum and PCBs (1999 EPA letter; 2014 EPA/Navy Determination); asbestos removal is not among its enumerated requirements.

- Limitations
- Sweep coverage is the CourtListener index only - it does not cover state-court records, asbestos trust claims, or non-U.S. jurisdictions. The craft has no name (NVR: NO NAME), so name-based coverage is the two hull designations plus the 'Boat Landing Stage' role label with an asbestos discriminator. The 8 'IX-519' docket hits are string collisions inside unrelated litigation (the hull token appears in document/docket numbering or party text); none is maritime or asbestos-related. Absence of indexed litigation does not prove no claim was ever filed - and as an unnamed, non-propelled service craft struck as equipment, IX-519 was an unlikely litigation target in any event.
