Adequately wet – sufficiently mix or penetrate with liquid to prevent the release of particulates. If visible emissions are observed coming from asbestos-containing material, then that material has not been adequately wetted. However, the absence of visible emissions is not sufficient evidence of being adequately wet.
Asbestos abatement projects – an activity undertaken to encapsulate, enclose, or remove 10 square ft and/or 16 linear ft or more of friable asbestos containing materials from buildings and other air contaminant sources, or to demolish buildings and other air contaminants sources containing 10 square ft and/or linear ft or more.
Category I non-friable asbestos-containing material (ACM) – asbestos-containing packing, gaskets, resilient floor covering, and asphalt roofing products containing more than 1 % asbestos.
Category II non-friable ACM – any material, excluding Category I non-friable ACM, containing more than 1 % asbestos, that when dry, cannot be crumbled, pulverized, or reduced to powder by hand pressure.
Commercial or Public Project - the demolition of one or more houses as part of an urban renewal project, a highway construction project, or a project to develop a shopping mall, industrial facility, or other private development.

Any structure, installation or building that was previously subject to this subpart is not excluded, regardless of its current use or function.
Friable asbestos material – any material containing more than 1 % asbestos that when dry, can be crumbled, pulverized, or reduced to powder by hand pressure. If the asbestos content is less than 10 %, verify the asbestos content by point counting using PLM.
Installation – any building or structure or multiple (more than one) buildings or structures at a single demolition or renovation site under the control of the same owner or operator (or owner or operator under common control) that is demolished or renovated within a 12-month period.
Leak-tight – solids or liquids cannot escape or spill out. It also means dust-tight.
Non-friable asbestos-containing material – any material containing more than 1 % asbestos that when dry cannot be crumbled, pulverized, or reduced to powder by hand pressure.
Owner or operator of a demolition or renovation activity – any person who owns, leases, operates, controls, or supervises the facility being demolished or renovated or any person who owns, leases, operates, controls, or supervises the demolition or renovation operation, or both.
Regulated asbestos-containing material (RACM) – (a) friable asbestos material, (b) category I non-friable ACM that has become friable, (c) category I non-friable ACM that will be or has been subjected to sanding, grinding, cutting, or abrading, or (d) Category II non-friable ACM that has a high probability of becoming or has become crumbled, pulverized, or reduced to powder by the forces expected to act on the material in the course of demolition or renovation operations regulated by this subpart.
Residential Exemption – A demolition or renovation of individual residential buildings having four or fewer dwelling units that do not meet the requirement of an installation and is not a part of a commercial or public project.
