—r 152 RADIOLOGICAL CLEANUP OF ENEWETAK ATOLL Master Sergeant J. S. Loggins, Engineer Construction NCQ. Accompanying them was Captain Charles E. Day, USA, from the Fielg Command Hawaii Office, assigned on a 2-week temporary duty (TDY) basis to provide radiological safety support for thefirst joint effort of the project.34 FIRST ARMY-NAVY TEAM: 5 APRIL-17 MAY 1977 Thefirst joint Army-Navyeffort of the project was removalof aggregate from a stockpile on Enjebi (Janet) Island to Lojwa (Ursula) Island for use in construction of the forward base camp. It was accomplished by four Army equipmentoperators and five Navy boat operators assigned TDYto the atoll for the aggregate operation. Procedures for accomplishing and supporting the operation were developed by the atoll commander, the H&Nsite manager, and Field Command’schieflogistician.35.36 The team used base support equipment—scooploaders, dump trucks, and landing craft, mechanized (LCM-8)—to move the aggregate. The bulk-haul system, which had previously been used to deliver soil for ERDA’s experimental tree farm on Enjebi, was used to transport the aggregate to Lojwa. With the bulk-haul system, the landing craft well deck was loaded directly with approximately 40 cubic yards of aggregate for each trip, instead of with one truck carrying only about 8 cubic yards of aggregate, This was the first use of bulk haul by a military team at the atoll. A year later, after extensive radiological safety testing, the procedure would be employed to improve capabilities for moving radiologically contaminated soil. Work began on 8 April 1977 under the supervision of Chief Boatswain’s Mate Roger Black. During the week, the team camped on Enjebiin trailer facilities originally established for the Lawrence Livermore Laboratory’s experimental tree farm. The Enjebi trailer camp was operated and maintained by two H&N-PTD employees. On weekends, the team returned to the main base camp on Enewetak Island. CPT Day implementedthe radiological safety program. Air samplers obtained from the Nevada Test Site were set up downwind of aggregate loading and offloading operations, and dustfilter masks were worn by personnelin the area. When the operation was completed on 9 May 1977, a total of 1,300 cubic yards of aggregate was stockpiled on Lojwa for use by the construction forces.37
