Establishing a state sandstone.

SB 5489 designates Wilkeson sandstone as Washington's official state sandstone. This procedural bill adds a new section to state law (RCW 1.20) to formally recognize the sandstone, which is quarried near Wilkeson, Washington. It has no policy impact or direct effect on residents, businesses, or government programs. The bill is purely ceremonial, following standard practice for designating state symbols.
