Narrative
On 10-16-17 enterprise personnel received notification of a possible leak at 7:00 am and company personnel arrived onsite at 7:20 am. It was determined to be the enterprise line (oth 13) at 10:15 (confirmed discovery). Notifications were made to the rrc and nrc (nrc #1193408). Clean-up remediation immediately began utilizing vacuum trucks and hydro excavators. Once the pipe was exposed, a pinhole was found in the 6 o'clock position.

Update (3/21/2018): this section of the pipeline has been cut and capped with no product flowing through. The previously scheduled tool run for 10/20/2017 was postponed. Tool run was done on 11/10/2017. Update (9/18/2018): accidents/incidents caused by equipment failure are trended and tracked in our operational containment program.
