This bill amends RCW 41.26.030 to include full-time wildland or aviation firefighters in the law enforcement officers' and firefighters' retirement system. It defines "full-time" as employment of at least 160 hours per month for more than six months in a year and expands the definition of "employer" to include the Department of Natural Resources for qualified firefighters. The bill also makes various reenactments and amendments to existing definitions within the retirement system, ensuring clarity regarding eligibility and benefits for different categories of firefighters and law enforcement officers.

Furthermore, the bill clarifies definitions related to the retirement system, including "Member," "Plan 1," "Plan 2," and "Service," while establishing how service credit is calculated, including provisions for military service and dual employment. It ensures that reduction efforts like furloughs or temporary layoffs do not impact the service credit earned for the month of work, thereby guaranteeing full credit for scheduled hours. Overall, the bill aims to enhance the retirement benefits framework and clarity for law enforcement officers and firefighters in Washington, recognizing their critical contributions.
