This bill establishes a new requirement for public works projects in Washington state that receive significant state funding. Specifically, it mandates that lumber used in the construction, reconstruction, alteration, repair, improvement, or maintenance of public buildings or projects, where state funds exceed $500,000 and cover more than half of the project's cost, must be procured in order of priority from Washington, Oregon, and the United States. There are provisions for waiving this requirement if it is deemed inconsistent with the public interest, if sufficient quality lumber is unavailable, or if compliance would increase costs by 10 percent or more. Waivers must be publicly announced and allow for public comment before a final decision is made.

Additionally, the bill includes a provision that addresses potential conflicts with federal requirements related to the allocation of federal funds to the state. If any part of the act conflicts with these federal requirements, that specific part will be inoperative only to the extent of the conflict, while the remainder of the act will continue to apply. This ensures that the rules adopted under this act will still comply with necessary federal conditions for receiving federal funds.
