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 transfer of funds is intended to support the local governments that handle emergency calls received from the regional system. The percentage of the excise tax to be transferred will align with the tax imposed under RCW 82.14.420.

Starting in calendar year 2026, the counties are required to make these transfers on a quarterly basis to the corresponding local governments. 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. This legislative action aims to enhance the funding and support for local emergency response systems, ensuring they are adequately resourced to handle public safety needs.
