One part of the current damage prevention rule requires operators, when advised of intended excavation, to give the excavator notice of whether there is or is not a buried pipeline in the area of excavation. This amendment deletes the requirement to give such notice when the operator does not have a pipeline in the area of intended excavation. This final rule will reduce the burdens and costs to pipeline operators, particularly those who comply with the current rule by participating in "one-call" systems. The amendment will enhance the effectiveness of established "one-call" systems by providing uniformity of response procedures for all utility participants.
