The bill establishes a new section in chapter 82.14B RCW that mandates counties located east of the Cascade mountains, with populations between 530,000 and 1,500,000, to allocate a portion of their excise tax revenues from the regional 911 emergency communications system to local governments that operate municipal public safety answering points. This allocation is based on the same percentage used for a specific tax imposed under RCW 82.14.420. The bill specifies that these funds must be transferred quarterly, starting in calendar year 2026, to support local governments that handle emergency calls.

Additionally, the bill defines a "regional 911 emergency communications system" as one operated by a county responsible for managing incoming emergency calls for multiple local law enforcement and fire response agencies. This legislative change aims to enhance funding for municipalities involved in emergency response, ensuring they receive necessary financial support for their operations.
