Regulatory Compliance
Prior to renovation, demolition, or maintenance activities, asbestos-containing materials (ACM) must be identified in accordance with:
US Environmental Protection Agency (US EPA)

National Emission Standards for Hazardous Air Pollutants (NESHAP)
Local Clean Air Agencies (e.g., Puget Sound Clean Air Agency)
Failure to identify ACM prior to disturbance may result in regulatory penalties, project delays, and environmental liability.
