The bill proposes the introduction of special license plates featuring an image of Mount St. Helens in Washington state, with an initial fee of $40 and a renewal fee of $30, as outlined in the amendments to RCW 46.17.220. The funds generated from these plates will be allocated to the Mount St. Helens Institute to promote education, stewardship, and science related to the volcano. Additionally, the bill amends existing statutes, including RCW 46.18.200 and RCW 46.68.420, to integrate the new license plate into the current framework for special plates and to ensure consistency in the language regarding fees and conditions for other special plates.

Moreover, the bill establishes eligibility criteria for cities to receive construction funds for public tennis facilities, prioritizing the most populous eligible city without existing facilities that have at least four indoor tennis courts for funding over a five-year period starting January 1, 2017. Maintenance funds will be directed to the city that has utilized construction funds as specified. The bill also mandates that at least 90 percent of funds from the Seattle Seahawks and Seattle Mariners special license plate accounts be allocated to their respective programs. A new section is introduced to define the "Mount St. Helens license plate," and the act is set to take effect on November 1, 2025.
