St. Louis County Emergency Communications Commission


Emergency Communications Commission

The ECC was created for the purpose of administering an emergency communication system including an inter-operable county-wide wireless radio communication network providing communications links that permit participating governmental entities to communicate within the geographic boundaries of the county. This includes the radio system, the emergency alert system and the enhancements to the 911 system.
