Narrative
On april 15, 2017, a local landowner, excavating with a front-end loader without notifying one-call, was performing an unapproved excavation activity - developing a fire pit - on the company's row. Due to one-call not being notified, the company did not mark the line with temporary markings. The damaged pipeline was, however, permanently marked within sight of the excavation on both sides. The landowner struck the pipeline, resulting in a 3'' x 3'' hole. The company scada system reported a leak indication at 1314 hours. Company personnel arrived at the scene at 1400 hours and confirmed the accident at 1430 hours. The national response center was notified by company personnel at 1528 hours. A loss of 105 barrels occurred with all barrels recovered. No injuries or fatalities occurred. Total costs attributed to this event are expected to be $124,500. The pipeline was placed back in service at 0805 hours on april 16, 2017. Remediation work is ongoing. Pipeline replacement of the permanent repairs to the affected pipeline will be performed with anticipated costs being reasonably certain, leading to the filing of this report as final. Any unanticipated costs not reasonably anticipated will result in a supplemental report being filed. The initial report included the pipeline coating being classified as "composite" from the form f 7000.1 pick list. Upon further investigation, the coating at the site of the accident was mastic with a wrap. The original supplemental report, filed on august 9, 2017, listed the accident local time as 14:30 on april 15, 2017. This time indicated when the company confirmed the accident met the telephonic reporting criteria in 49 cfr 195.50 (reference the reporting instructions on page 6 of 31 of PHMSA's instruction for form PHMSA f 7000-1). It may be noted that the written reporting criteria in 49 cfr 195.52 is slightly different than the telephonic reporting requirements; it may be inferred that this is due to there being no other location on the reporting form for the accident time meeting the reporting threshold to be reported. Nevertheless, the company is reporting on this supplemental report that the local time in section a4 is 13:14, even though at this time the company only had a scada indication that something had changed on the pipeline pressure profile; the company at 13:14 did not know what, if anything, had actually occurred, and subsequently sent personnel to the area to investigate (the scada indication could have been due to a faulty flow meter, a transmitter malfunction, or other fault in the communication chain; investigation is required prior to determining if the reporting threshold had indeed been met). Once the personnel had determined the telephonic reporting criteria had been met the call to the national response center was made. Therefore, the company is submitting 13:14 as the local time at the specific request of PHMSA but maintains the correct time is 14:30, in accordance with the instructions, when the telephonic reporting criteria was met.
