Navy to conduct underwater training in Outer Apra Harbor
ASAN, Guam (April 8, 2019) – U.S. Navy Explosive Ordnance Disposal Mobile Unit (EODMU) 5 will conduct routine underwater detonation (UNDET) training in outer Apra Harbor April 12 from 8 a.m. to 4 p.m.
EODMU-5 will detonate a total of five pounds of explosives at the designated UNDET location on a sandy area of the sea floor.
For the safety of the public and participants involved, the Coast Guard will establish safety zones to restrict access in the vicinity of the training area.
EODMU-5 performs routine underwater detonation training to develop the skills needed to be ready to rapidly respond to operational missions and unexploded ordnance support on Guam and the Commonwealth of the Northern Mariana Islands.
The Navy conducted a multi-year environmental analysis, which the National Marine Fisheries Service, under the Marine Mammal Protection Act and Endangered Species Act, granted the Navy authorization to conduct underwater detonation training. The Navy is a committed environmental steward and employs protective measures to safeguard marine resources.
For the safety of personnel and marine life, the area will be visually cleared by divers and by lookouts on the surface before, during and after the exercise. All activity will cease temporarily if a person or marine life is seen in the area.
