An excavator who fails to comply with the notification requirements may be liable not only for damages, see id . See id .

The excavators assert that the notification centers require subsequent notices every ten days even though the location of the excavation has not changed from the location stated in the initial notice. The excavators argue that the subsequent notice requirement has increased the number of calls to the notification centers to such a level that the notification centers are not able to adequately meet the demand. The end result, the excavators claim, is that many requests have not been responded to in a timely manner or go unanswered. The underground facility owners contend that the subsequent notice requirement is necessary to ensure that underground facility lines remain marked at all times. The underground facility owners claim that lines clearly marked after the initial notice by excavators disappear or are erased due to the changing conditions, both natural and man-made, at the excavation location.
