The Navy today announced it will shut down its Extremely Low Frequency (ELF) Communications System on Sept. 30, 2004 and cease operations at the two ELF transmission facilities at Clam Lake Navy Radio Transmitter Facility, in the Chequamegon National Forest, Wisconsin, and the Republic Navy Radio Transmitter Facility, in Michigan's Escanaba State Forest.

The Navy used the ELF system to maintain secure communications with submarines at sea. Improvements in communications technology and the changing requirements of today's Navy made the ELF communication system no longer necessary.

The Nave is working closely with the U.S. Forest Service and the Michigan Department of Natural Resources to develop timelines of key closure dates and milestones. These include National Historical Preservation Act requirements, land disposition, and environmental assesment under National Environmental Policy Act.

The closure process is expected to take up to three years.
