Incident Narrative
"ON SEPTEMBER 18TH, 2018 APPROXIMATELY 17.2 BARRELS OF DIESEL FUEL WAS RELEASED FROM THE NORTHWEST PRODUCTS #1 LINE NEAR MILEPOST 254. THERE WERE NO INJURIES OR FATALITIES. THE REPAIR OF THE PIPELINE, AS WELL AS REMEDIATION HAS BEEN COMPLETED. THE LEAK WAS CAUSED BY A LINE STRIKE DURING AGRICULTURAL ACTIVITIES BEING PERFORMED BY THE LAND OWNER. NO ONE CALL WAS PERFORMED FOR THE RIPPING ACTIVITIES PERFORMED. LANDOWNERSHIP AGREEMENT CHANGED IN 2018, WITH DIFFERENT CREWS WORKING THE FIELD IN PRIOR YEARS. THE FIELD HAD NOT BEEN WORKED THE THREE YEARS PRIOR DUE TO RYE GRASS CROP ROTATION. THE NEW CREW WAS NOT FAMILIAR WITH THE DEPTH AND LOCATION OF THE PIPELINE ACROSS THE PROPERTY, THOUGH MARKERS WERE IN PLACE AT THE PROPERTY BOUNDS. 300 FEET OF PIPE WAS REPLACED TO REPAIR THE SITE OF THE RELEASE, AS WELL AS OTHER INDICATIONS OF PRIOR PIPE DAMAGE ACROSS THE FIELD. DURING THE LINE REPLACEMENT, THE LINE WAS ALSO LOWERED ACROSS THIS PROPERTY."
