Narrative
At approximately 17:52 magellan operations control received a scada alarm of a pressure drop on the #1-6" pipeline from enid to ponca city and implemented magellan's code red procedure. The line was immediately shut down and isolated by closing rov's at enid and ponca city. Shortly after receiving the scada alarm, a telephone call was received from a third party contractor stating that they had struck our line with trenching equipment causing a release of crude oil that was contained within the excavated trench. Magellan field personnel were dispatched and arrived on site to confirm that the released product (crude oil) was contained in the trench, thus minimizing impact. The site was safely secured and product recovery was initiated utilizing vacuum trucks and portable frac tanks. The line was repaired by replacing the damaged line pipe with new, pre-tested pipe. The welds were x-rayed and the line was returned to service per magellan's written start-up plan. Approximately 749 cubic yards of impacted soil was remediated. Item g3, #17 description of cga-dirt root cause which is listed here because of insufficient room. Pipeline was located and marked on both sides of road per the trenching contractor's one call ticket and a discussion with contractor's contact listed on the ticket. The discussion with the contractor revealed that they were headed north on the east side of county road_n3180,but by the time they would near the magellan pipeline, they would be on the west side of county road n3180. Accordingly, magellan marked from the west side ditch out into the field approximately 50' to the west. Magellan also marked the east side ditch to the aerial marker for reference. However, the trenching contractor was still excavating on the east side of county road n3180 road when it struck the magellan pipeline. Additionally, the trenching contractor did not contact magellan as they neared the magellan pipeline so that we could pothole the pipe; nor did the contractor white line the area to be excavated as per the 2015-2016 okie811 excavator guide..
