The proposed USCG project is part of the National Distress and Response System (NDRS) Modernization Project, now called Rescue 21 (R21), and would provide SAR service to portions of Peril Strait and Sergius Narrows not currently served by existing SAR communication facilities. The proposed R21 facility would provide support for very-high frequency (VHF) communication (including Digital Selective Calling (DSC) and National Weather Service broadcasts), ultra-high frequency (UHF) antennas, and microwave communications in order to provide radio signal in the Peril Strait area. The proposed facility would occupy less than 1/2 acre and consist of a communication tower, communication hut, generator hut, propane fuel tanks, solar array, helicopter pad, and all necessary electronic equipment. Rescue 21 is the Coast Guard’s advanced command and control communications system and was created to better locate mariners in distress and to save lives and property at sea and on navigable rivers. Rescue 21 allows the USCG to more accurately identify the location of callers in distress using DSC radio transmissions, thereby significantly reducing search time. The R21 Alaska program is designed to provide an integrated emergency communication system extending 20 nautical miles from the shoreline with the following services: Monitoring of distress calls from vessels (MAYDAY); Improvement in communications for other operational missions, including search and rescue, maritime law enforcement, maritime pollution prevention and response, and homeland security/national defense; and Support for U.S. compliance with international treaties including DSC capability in Global Maritime Distress and Safety System, in accordance with the International Maritime Organization of Life at Sea Convention. These services would be accomplished by the following actions: Reducing coverage gaps in the current VHF system; Increasing channel capacity, which would allow for simultaneous communications on multiple channels (including VHF Channel 16); Having DSC capability that would quickly provide a vessel’s name, exact location, nature of distress, and other vital information when used in conjunction with an integrated global positioning system (GPS) receiver
