Narrative
On may 6, 2020 at 12:45 pm cdt, product was visible near the line 1 mp 801 valve by the technician when he arrived at the valve site to complete scheduled maintenance. The edmonton control center was contacted and the line was shut down to investigate. Additional crews were dispatched to determine the source of the product. After removing standing water and excavating the area, it was discovered that the seal packing pipes had cracked causing approximately 1 cup of crude oil to be released. The internal investigation determined that frost heave caused the piping to crack. On the evening of may 8, 2020 the plan to replace the piping was finalized and it was determined that the costs for repair and clean up would meet the requirement for an nrc notification. The nrc was notified at 9:05 pm cdt (#1276936). On may 9, 2020 the seal packing and body bleep piping was replaced and the line placed back into service at 2:35 am cdt. A 48-hour update to the nrc was made on may 10, 2020 at 4:35 pm cdt (#1277006). Upon completing the valve repair and in an effort to remediate the impacts, enbridge performed additional excavation activities to address the release. Preliminary excavation resulted in the discovery of impacted soils in unanticipated locations. Consequently, enbridge has initiated a site investigation designed to further assess potential impacts from the valve release as well as potential previous impacts. The goal remains to remediate to applicable environmental standards with the possibility of additional excavation. Due to the remote location of the site, costs are inflated for dispatching qualified professionals to perform investigatory work and impacted materials must be transported great distances for disposal at permitted facilities. The actual volume released at mp 801 was 0.0015 barrels. The PHMSA portal does not recognize volumes less than 0.1 barrels therefore that is the volume entered.
