Narrative
A 4-inch plastic natural gas main was ruptured by a backhoe while a contract crew was installing a storm drainage system. Once the incident was made safe it was identified that natural gas service was loss to approximately 355 customers and costs associated with the incident 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, however, it appears the facility was not located properly. Additional nrc report number 1278001 was created for the same event after a supplemental call was placed with the nrc to update the initial telephonic notice.
