CE oo — Radiation Safety and Cleanup Preparations 209 CHANNEL CLEARANCE: SEPTEMBER 1977 Channel clearance operations commenced on 15 September 1977 when u.s. Navy Underwater Demolition Team Eleven (UDT Eleven) cleared the approaches to Ananij (Bruce), Aomon and Lujor by chain dragging. Later that week, explosives were used to complete clearance of the beach approach to Ananij andto clear a channel into Runit (Figure 4-12).59 On 21 September 1977, UDT Eleven established a temporary camp at Enjebi and proceeded to complete the channel clearance mission in the northern half of the atoll, including channels into Enjebi, Bokoluo (Alice), and Louj (Daisy). They returned to Enewetak Camp 4 days later and completed their work in the southernislands. UDT Eleven completed an estimated 45 to 60 days channel clearance and demolition workin 16 days. They used 41,400 pounds of explosivesin nine separate demolition operations to improve channels and access to landing beaches on fourislands, and they employed chain drag procedures to clear obstacles from eight channels. In addition to completing all tasks assigned in the OPLAN, the team placed marker buoys on ten landing beach approaches, resurveyed four channels after explosive clearance operations, andleft a wealth of lagoon and channel information for use by the JTG.60.61 A week after the channel into Lujor was cleared, it was put to use. On 22 September 1977, several members of the FRST were diverted from the debris survey of Enjebi to begin the radiological survey and characterization of Lujor. By then, additional in situ vans had arrived so that the ERSP was able to begin the characterization of Lujor while continuing the Enjebi soil survey, although at a slower pace than originally planned.
