This manual documents the structure and function of the asbestos-containing material (ACM) environmental management system (EMS), as prescribed by the Massachusetts Department of Environmental Protection (MA DEP) for the University of Massachusetts Amherst (UMass). The manual applies to all UMass departments, personnel, and work conducted on campus grounds. The ACM EMS at UMass is the result of an administrative consent order (ACOP-WE-06-C001-27A-SEP-EMS) that was received and signed off on October 27, 2006. The consent order required that UMass design and implement an EMS for the appropriate management of known and suspected ACM on campus. Furthermore, the consent order required that the ACM EMS reflect the size, complexity and environmental conditions and circumstances of UMass operations that will or may impact or encounter ACM.
