The bill proposes the introduction of special license plates featuring an image of Mount St. Helens in Washington state, with an initial fee of $40.00 and a renewal fee of $30.00. It amends existing laws to allocate funds generated from these plates to the Mount St. Helens Institute, promoting education, stewardship, and scientific initiatives related to the volcano. The bill also reenacts and amends several sections of the Revised Code of Washington (RCW), including RCW 46.18.200, 46.17.220, and 46.68.420, to incorporate the new license plate and its associated fees, while ensuring that proceeds from various special license plates support relevant programs.

Additionally, 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. Maintenance funds will be prioritized for the first city that utilizes construction funds from a specific chapter of Washington law. The bill also specifies the allocation of funds from the Seattle Seahawks and Seattle Mariners accounts for specific programs, and it defines the "Mount St. Helens license plate," with the act set to take effect on November 1, 2023.
