Concerning naturally occurring fibrous silicate materials.

SB 6213 updates Washington State's regulations for naturally occurring fibrous silicate materials (minerals similar to asbestos that occur naturally in building materials) by lowering the threshold for labeling and restrictions. Starting January 1, 2025, building materials containing more than 0.25% of these materials must be labeled, down from the previous 1% limit. The bill exempts residential construction and materials already in use under existing contracts from new restrictions. It also requires facility owners to inspect for these materials and maintain management plans, with inspections mandated every five years.
