Incident Narrative

AT APPROXIMATELY 0910, ON DECEMBER 9, 2014, A KINDER MORGAN OPERATOR, WHILE PERFORMING FUGITIVE EMISSIONS LEAK TESTING, NOTICED GASOLINE ODOR AND DISCOVERED A LEAK FROM UNDER THE TANK CHIME OF BREAKOUT TANK CC-12 NEAR THE TANK VALVE. THE VOLUME OF THE RELEASE TOTALED ONLY 0.4 GALLONS. THE TANK WAS PROMPTLY DRAINED THEN REPAIRS AND REMEDIATION WERE BEGUN. AT THE TIME OF THIS REPORTING, THE CAUSE HAS YET TO BE DETERMINED AND THIS REPORT WILL BE SUPPLEMENTED. NOTE: PART A, #6 THERE WERE TWO NRC NOTIFICATIONS MADE. THE FIRST (#1102994) @ 0920 NOTIFIED OF A THREATENED RELEASE AND THE SECOND (#1103006) CONFIRMING THE RELEASE AND THE PROBABILITY THAT THE $50,000 REPORTING THRESHOLD WOULD BE EXCEEDED. SUPPLEMENTAL UPDATE: A DEFINITIVE ROOT CAUSE OF THE LEAK COULD NOT BE ESTABLISHED THROUGH METALLURGICAL ANALYSIS BECAUSE THE COUPON SAMPLE WAS ARC GOUGED. THIS ARC GOUGING OCCURRED WHEN CUTTING THE COUPON; EFFORTS WERE MADE TO PREVENT ARC GOUGING OF THE 16-INCH SUCTION/FILL LINE, WHICH CONTRIBUTED TO THE GOUGING. NOTWITHSTANDING, ORIGINAL AND SUBSEQUENT FIELD EXAMINATION DETERMINED THAT THE MOST LIKELY CAUSE OF THE CRACK IN THE METAL OF THE SUMP WAS INCREASED STRESS PUT ON THE METAL BY THE SUCTION/FILL LINE THAT HAD LOST ITS SUPPORT DUE TO WASHING OUT OF THE SOIL BENEATH THE TANK. IN ADDITION, THE TANK VALVE WAS ALSO NOT VAULTED (AN OLDER DESIGN) FURTHER ALLOWING MOVEMENT. 11/15/16 UPDATE: SUPPLEMENTING AND FINALIZING THIS REPORT PER CSFM/PHMSA REQUEST. MY RECORDS SHOW THAT I INTENDED ON CLOSING THIS REPORT ON 3/3/15. I MUST HAVE NOT SELECTED THE ""FINAL"" BUTTON ON PART A.
