Asbestos-containing material (ACM)

Material containing asbestos as defined by the applicable regulatory or analytical framework. Appearance alone does not reliably establish whether a material contains asbestos.

Why it matters

A Phase I ESA is not automatically an asbestos survey. Sampling, disturbance assessment, renovation planning, and management procedures require a defined scope and appropriately qualified personnel. Material condition and planned work influence the next step.

In practice

A project example

A renovation that will disturb suspect flooring needs suitable evaluation before demolition; an environmental transaction report is not a substitute for that work.
