What percentage of asbestos by weight qualifies as asbestos-containing construction material (ACCM)?

To determine whether a material is classified as asbestos-containing construction material (ACCM), it is important to recognize that the Environmental Protection Agency (EPA) defines any material that contains 0.1% or more asbestos by weight as asbestos-containing. Hence, the threshold for ACCM is set at 0.1%. If a building material has this percentage or higher, it falls under the regulatory framework that necessitates specific handling and disposal procedures due to the health risks associated with asbestos exposure. Using this guideline, materials below this threshold would not be classified as ACCM and would not require the same management practices or oversight concerning asbestos handling. This definition is crucial to ensure that inspectors and construction professionals recognize and manage the risks associated with asbestos in building materials effectively.
