    Finding
    Documented for this hull: laid down 15 December 1942 at Alameda, CA by Bethlehem-Alameda Shipyard, Inc., under Maritime Commission contract (MC hull 679); launched 20 February 1944, sponsored by Mrs. James Reed; delivered to the Navy and commissioned 18 September 1944, Capt. N. S. Haugen, USCG, in command. WWII service: Noumea/Guadalcanal/Espiritu Santo (~3,500 troops embarked) Nov-Dec 1944; Hollandia and Leyte Feb-Apr 1945; ~5,000 troops embarked at Seattle for Okinawa (reached 2 July 1945 via Pearl Harbor, Eniwetok, Ulithi); Saipan 12-13 July; Norfolk arrival 4 August 1945 during voyage repairs. Atlantic trooping: Marseille (French Navy passengers), a run repatriating ~3,765 former Italian POWs (Newport News return 19 Oct 1945), and two more France round-trips (Le Havre, Marseille) through mid-December. Pacific return: Pearl Harbor, Yokosuka, Seattle (30 Jan 1946); March Okinawa round-trip (>4,800 troops to San Francisco); New York arrival 24 April 1946. Decommissioned and returned to the Maritime Commission 8 May 1946; name struck from the Navy list June 1946. Transferred to the Army, which renamed her General Hugh J. Gaffey; re-acquired 1 March 1950 and assigned to MSTS (not re-commissioned); to MARAD temporarily 4 November 1968 for NDRF Suisun Bay, permanently 31 August 1969; struck 9 October 1969; re-acquired 1978, redesignated IX-507, placed in service November 1978 at Bremerton, WA as barracks ship for crews of ships in major overhaul. Namesake note: the transport was the second Navy ship named for Capps - NHHC's own DD-550 entry confirms destroyer USS Capps was in commission June 1943-January 1947, overlapping this ship's entire commissioned period (the 'second ship' ordinal itself rests on secondary sourcing).

    Finding
    The federal regime under which this hull's 16 June 2000 sinking was conducted: the MPRSA general permit 'Transport of Target Vessels' (40 C.F.R. 229.2) as interpreted by the 1999 EPA-Navy letter and this Determination requires a pre-sinking PCB survey/sampling of each SINKEX vessel, removal of transformers/capacitors and readily detachable PCB-containing shipboard materials, certification of the remediation, and reporting per-vessel - targeting materials that degrade the marine environment. The document contains zero asbestos-removal requirements; the SINKEX prep regime as documented was PCB-focused.

    A 600-psi steam transport built 1942-44 and operated through 1969 sits entirely inside the documented Navy/Maritime Commission asbestos era. Era-standard applications aboard a steam transport of this type and period were boiler and steam-drum insulation, steam-line lagging between boiler rooms and machinery spaces, valve and flange gaskets, machinery packing, and accommodation/fire insulation; the 1978-93 barracks-hulk reuse and the 1999 Mare Island partial scrapping were disturbance events on era-built material.
