The bill amends several sections of the Revised Code of Washington (RCW) related to naturally occurring fibrous silicate materials, specifically addressing the definitions and regulations surrounding asbestos and asbestos-containing building materials. Key changes include the redefinition of "asbestos-containing building material" to include materials with more than 0.25 percent asbestos by weight or area, down from the previous threshold of one percent. Additionally, the bill introduces the term "commercial aggregates," which refers to materials like sand and gravel that may contain naturally occurring fibrous silicate materials. It also clarifies the definition of "naturally occurring fibrous silicate material" and includes specific labeling and inspection requirements for facilities dealing with asbestos.

Furthermore, the bill outlines exemptions from certain regulations, such as the prohibition on the use of asbestos-containing materials in new construction or renovations, which does not apply to commercial aggregates or materials with a low asbestos content (0.25 percent or lower). It also stipulates that owners of facilities engaged in specific industries must conduct inspections for asbestos and maintain an asbestos management plan, although these requirements are exempt for materials that meet the specified low asbestos content. Overall, the bill aims to enhance public health protections while providing clarity on the handling of asbestos and related materials.
