Alabama Regional Communications System
The Alabama Regional Communications System (ARCS) is a radio/alert notification communications district with responsibility for providing user-based administration for operations and maintenance of the interoperable communications system that serves Calhoun County, Alabama and Talladega County, Alabama. The Motorola trunked radio system is licensed by the Federal Communications Commission (FCC) to operate on radio frequency spectrum in the 800 megahertz (MHz) public safety band.
==Background==
The Calhoun-Talladega 800 MHz communications system was originally developed and installed to enhance interoperability and to provide alert and notification for the community during the destruction of chemical weapons at the Anniston Army Depot (ANAD). The communications system was funded and maintained through a federal grant known as the Chemical Stockpile Emergency Preparedness Program (CSEPP), a joint United States Army and Federal Emergency Management Agency (FEMA) program designed to provide community education and emergency preparedness resources in the event of a chemical agent emergency. The original communications system, a Legacy system with analog trunking, went on-the-air in 1998 and quickly became the primary means of two-way communications for most public safety agencies in Calhoun and Talladega Counties, replacing their standalone conventional radio repeaters. In 2006, the CSEPP communications system was upgraded to a digital Project 25 Motorola Type II SmartZone version 7.4 linear simulcast/multicast trunked 800 MHz communications system.
The facilities at ANAD, known as Anniston Chemical Activity (ANCA), stored approximately seven percent of the nation's chemical weapon's stockpile including VX (nerve agent) and Sarin (GB) agent. ANAD was one of nine United States Army installations in the United States that stored chemical weapons. The United States Army began incinerating the stored weapons on August 9, 2003. The destruction of ANAD's chemical weapons stockpile was controversial, in part, because of the potential danger to the surrounding community should an incident occur during weapons disposal operations. In September 2011, the US Army's Chemical Materials Agency (CMA) successfully completed the safe elimination of ANAD’s chemical weapons stockpile.
