Narrative
A 2-inch steel natural gas main was ruptured near its tap on a 4-inch steel main by a t&j industries contract crew while installing sewer main by boring. Once the incident was made safe and the costs associated with the incident was being tallied it was determined that required milling and resurfacing repairs to the highway by the local government, repairs to the affected pipeline and emergency response would exceed the $122,000 threshold for reporting where the timeline for question a4 was met above and 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 attempt to pothole where the facility was marked and damaged. Additional nrc report number 1311561 was created for the same event after a supplemental call was placed with the nrc to update the initial telephonic notice.
