The bill establishes a new section in chapter 82.14B RCW to provide funding for municipalities participating in regional 911 emergency communications systems. Specifically, it mandates that counties located east of the Cascade mountains with populations between 530,000 and 1,500,000 must transfer a portion of their excise tax revenues from the 911 system to local governments that operate municipal public safety answering points. The percentage of the tax to be transferred will align with the existing tax imposed under RCW 82.14.420.

Starting in calendar year 2026, these transfers must occur quarterly, ensuring that local governments receive the necessary funding for dispatching and handling emergency calls. The bill defines a "regional 911 emergency communications system" as one operated by a county that manages incoming emergency calls for multiple local law enforcement and fire response agencies.
