    "Fugitive Dust" means the particulate matter not collected by a capture system that is entrained in the ambient air and is caused from human, animal, and/or natural activities, such as, but not limited to, movement of soil, vehicles, equipment, blasting, and wind.
    "Trenching" means the construction of a narrow excavation, in relation to its length, made below the surface of the ground for purposes of facilitating the installation and repair of underground utilities.

    "Renovation" means altering a facility or one or more facility components in any way, including the stripping or removal of RACM from a facility component. Operations in which load-supporting structural members are wrecked or taken out are demolitions.
    "Regulated asbestos containing material" or "RACM" means (a) Friable asbestos material, (b) Category I nonfriable ACM that has become friable, (c) Category I nonfriable ACM that will be or has been subjected to sanding, grinding, cutting, or abrading, or (d) Category II nonfriable 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 40 CFR 61, Subpart M.

    If these activities are involved, see PDEQ Asbestos webpage or contact PDEQ at (520) 724-7400 for permitting and notification requirements.
