S.L. 2025-21 added a definition of soft dig technologies (air or water pressure with vacuum extraction) and includes them in nonmechanized equipment, which is directly relevant to hydrovac work in the tolerance zone.
Tolerance Zone

The tolerance zone is 24 inches on either side of the mark, or half the diameter plus 24 inches (N.C.G.S. 87-117). Soft dig technologies count as nonmechanized equipment.
