When conducting an asbestos abatement operation that is not a small-scale, short-duration project, what amount of asbestos-containing material triggers the requirement to use Asbestos Model Accreditation Plan-accredited workers?

Response actions other than a small-scale, short-duration project must be designed and conducted by Asbestos Model Accreditation Plan (MAP)-accredited persons. See 40 CFR part 763.90(g). Additionally, the asbestos National Emission Standards for Hazardous Air Pollutants (NESHAP), Occupational Safety and Health Administration (OSHA), state and local training requirements may apply.
