Leaders at Thurston County’s 911 dispatch center say the radio system that emergency responders use to talk to dispatchers and each other is outdated and they are asking state lawmakers for the ability to collect more sales tax to pay for a $30 million upgrade. TCOMM 911 handles emergency calls and dispatches first responders in Thurston County with the exception of Washington State Patrol. It also owns and operates the county’s public safety radio system. Olympia Fire Chief Gregory Wright told a Senate committee last week that Thurston County crews are using the same radio technology that was around when Wright started his career. “The one thing that all fire, EMS and law enforcement officials know is that our communications infrastructure is weak and needs to be replaced. ..,” he said. “Everything else that we do has changed, but we’re still using old technology.”
