Incident Narrative

AT APPROXIMATELY, 1120 ON NOVEMBER 20, 2017, THE CONCORD OPERATOR DISCOVERED THAT THE PLAINS ALL AMERICAN (CUSTOMER INCOMING TRANSFER LINE) INCOMING SAMPLE TUBE COMING FROM THE PIPELINE INTO SAMPLE HOUSE HAD SEPARATED AND DIESEL WAS FLOWING FROM 3/8"" TUBING ONTO THE SAMPLE HOUSE FLOOR AND FLOWING OFF ONTO ADJACENT SOIL. THE VALVE FROM THE TUBING WAS IMMEDIATELY CLOSED AND THE PIPELINE SHUTDOWN. TELEPHONIC NOTIFICATIONS WERE MADE. THE RELEASE RESULTED IN IMPACTED/STAINED SOIL 10 FEET LONG BY 2 FEET WIDE. APPROXIMATELY 1.5 FEET OF IMPACTED SOIL WAS REMOVED DOWN TO A CLAY BOTTOM WITH DIESEL PRODUCT SITTING ON TOP OF THE CLAY WHICH WAS REMOVED VIA ABSORBENTS. SUBSEQUENT INVESTIGATION DETERMINED THE RELEASE AMOUNT TO BE 14.5 GALLONS (0.35 BBL) ALL OF WHICH WAS RECOVERED. THE 3/8-INCH STAINLESS STEEL TUBING SEPARATED AT THE NUT AND BULK-HEAD FITTING AT THE SAMPLE HOUSE. INSPECTION OF THE NUT, FERRULE AND THE BULKHEAD SHOWED SIGNS OF WEAR DUE, MOST LIKELY, TO INCORRECT INSTALLATION. VIBRATION DUE TO THE LOOSE FERRULE ON THE TUBING CONTRIBUTED TO THE FAILURE. NOTE: PART C, 4. YEAR ITEM INVOLVED IN ACCIDENT WAS INSTALLED: TUBING/FITTING INSTALLED AS PART OF A LARGER PROJECT IN THE MID-EIGHTIES. WE ARE NOT EXACTLY SURE WHEN THIS PARTICULAR SYSTEM WAS ADDED.
