Which agency mandates the air sampling methods after asbestos abatement?

The agency that mandates the air sampling methods after asbestos abatement is primarily the Environmental Protection Agency (EPA). The EPA established regulations and guidelines that specifically address the standards for asbestos management, including post-abatement air sampling. This mandates that air samples be collected and analyzed to ensure that airborne asbestos fibers are below permissible levels, assuring the safety of workers and the general public after an abatement project.

While OSHA provides regulations related to worker safety and exposure limits related to asbestos, it does not specifically mandate the air sampling procedures in the context of abatement projects. AHERA, on the other hand, deals with asbestos in schools and outlines the responsibilities of local educational agencies regarding asbestos management, including inspection and management plans, but it is not primarily focused on setting air sampling methods. NIOSH conducts research and provides recommendations and guidelines but does not have the regulatory authority to mandate air sampling methods after abatement.

Therefore, while OSHA and other agencies play important roles in asbestos management, the EPA is the correct choice as it specifically addresses air sampling requirements post-abatement.
