The bill creates a new law by adding a new section to chapter 1.20 RCW that designates "The Wilkeson sandstone" as the official sandstone of the state of Washington. It is presented as "NEW SECTION. Sec. 1." and was introduced in the 2025 Regular Session (69th Legislature). This is a statutory designation of a state symbol and does not change criminal penalties, create a new crime, or alter procedural law. The extracted text does not include an effective date, a specific new section number within chapter 1.20 RCW, any definition or description of what "Wilkeson sandstone" means, or any implementation, enforcement, or funding provisions. These omissions are not filled in by the provided facts.

The practical effect would be largely symbolic: the bill places a statewide, statutory designation naming "The Wilkeson sandstone" as Washington’s official sandstone, but it does not create any new programs, funding, duties, deadlines, or enforcement responsibilities. There are no administrative or fiscal changes specified, so agencies and taxpayers should not expect direct costs or new obligations from this enactment as drafted. The most directly affected entity is the State of Washington in a statutory sense because the designation is added into chapter 1.20 RCW, but no state agency is assigned responsibilities. Key details are missing—there is no effective date, no definition of what "Wilkeson sandstone" means, and no specific section number within the chapter—so how the designation might be used or interpreted in practice remains unclear.
