Narrative
A 6-inch steel main was ruptured by a contract crew while directional drilling to install a traffic signal conduit. 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 verify location by test-hole (pot-holing).
