Excavation can uncover asbestos, for example naturally occurring asbestos in the ground, underground water pipes or telecommunications pits. There are two classes of licence. Class A covers removing any amount of asbestos or asbestos-containing material (ACM) of any kind: friable, non-friable, and asbestos contaminated dust (ACD). A Class B licence covers any amount of non-friable material and the ACD that comes with removing it. No licence is required for non-friable material up to 10 m2 in area, or for ACD that is linked to removing under 10 m2 of non-friable material or that is only minor contamination unrelated to removing asbestos. The PCBU that commissions removal must ensure a removalist holding the right licence does the work unless the regulations say none is needed.
