Narrative
A 6-inch steel main was ruptured by a contract crew while installing a sewer line. Once the incident was made safe it was identified that repairs to the affected pipeline would exceed the $50,000 threshold for reporting where the national response center (nrc) was contacted at that time. Notification to the one-call center was made where the main was correctly located, however, the excavator failed to maintain locate markings. An additional nrc report number was not created for the same event after a 48 hour supplemental call was placed with the nrc.
