What do I do if the marked underground facilities are in conflict with the excavation I plan to do and I need to excavate on them?
An example of this could be placing a fence within the 24 inch tolerance zone of a marked facility. A tolerance zone is 24 inches from the outer edge of either side of a marked underground facility. You may excavate within marks that are present; however, SSOCOF recommends that you hand dig. Use of mechanized equipment within the tolerance zone requires supervision by the excavator.
