Narrative
On june 19, 2018 at approximately 18:05 the control center was notified by a private citizen of a petroleum odor in the area of darby creek. Both sunoco pipeline lp (splp) pipelines (8" & 12" refined products) in the area were already shut down due to a planned scheduled outage on june 18, 2018. The control center immediately notified field operations of the report and personnel were dispatched to the area to investigate. After arrival and upon further investigation a petroleum odor and light sheening along the bank of darby creek was noted. Additional response personnel were dispatched and osro contractors arrived on site at approximately 20:45 and deployed boom to contain the sheen by approximately 21:45 and began collection activities. Although there were no operational indications of release from either company pipeline crossing of darby creek, a company incident command team was setup to monitor osro activities and perform further investigations into the product source, including establishing geo-probe monitoring locations, potholing to assess for any indications of product, additional excavation, and pressure testing of the two pipelines. On june 16, 2018, nrc report (1215471) was filed at 13:45 by a private citizen concerning a sheen in darby creek, however splp was not contacted. On june 19, 2018, upon becoming aware of the sheening and responding, splp filed nrc report (1215816) noting that the source of the sheening was undetermined. The 48hr follow up nrc report (1216057) was filed on june 21, 2018 noting the source remained unknown. At approximately 11:45 on june 26, 2018, the splp 12" point breeze to montello pipeline was confirmed as the leak source. Nrc report (1216488) was filed at 13:37 confirming such. The 48hr follow up nrc report (1216699) was filed on june 28, 2018 at 13:14 and provided that an estimated volume of 400 bbls of gasoline was released. The pipeline remained shut down from the scheduled shut down on june 18, 2018 through the remainder of the investigation and repair process. The failed pipe was fully excavated, removed and replaced. The failure was located in an area of disbonded coating on the inner radius of a field bend and appeared to be in a crack located in an area of external corrosion. The failed pipe was preserved and sent to a 3rd party laboratory for metallurgical analysis to fully determine the cause. The 12" point breeze to montello pipeline was refilled on july 1, 2018 at 14:30 and normal operation began at 17:57 that same day. The third party metallurgical analysis report concluded that the leak was due to external corrosion that formed a corrosion trough whose thinned cross section allowed environmentally assisted cracks to initiate and propagate through-wall due to the elevated hoop stress. Two types of environmentally assisted cracking were observed, corrosion fatigue and hydrogen cracking. The area of external corrosion and ultimate failure were located on the inner radius of a field bend under an area of disbonded coal tar coating.
