Incident Narrative

AT 1242, 8/8/13, DURING A STATION WALK-AROUND INSPECTION, THE OPERATOR NOTICED A VISUAL INDICATION FROM THE TANK LEAK SENSOR SYSTEM AT BREAKOUT TANK CC 9. THERE WAS ALSO A NOTICEABLE ODOR OF GASOLINE NEAR THE TANK, BUT NO STAINING. THREATENED RELEASE NOTIFICATIONS WERE MADE AND LOCAL OPERATIONS BEGAN EMPTYING THE TANK. AT 1404, WHILE SWABBING THE SENSOR TUBE, IT WAS DISCOVERED THAT THE CABLES WERE WET WITH PRODUCT AND INDICATED 100% LEL. FOLLOW-UP RELEASE NOTIFICATIONS WERE MADE AND THE TANK WAS EMPTIED BY 1700 THAT AFTERNOON. SUBSEQUENT INVESTIGATION FOUND A LAP-SEAM WELD CRACKED MOST LIKELY DUE TO FILLING/EMPTYING OF THIS DRAIN-DRY STYLE BREAKOUT TANK. 'NOTE: PART A, #6. ORIGINAL NRC 'THREATENED RELEASE' NOTIFICATION REPORT #1056503 MADE @ 1304, FOLLOW-UP NRC REPORT #1056510 MADE AT 1415 CONFIRMING THE RELEASE. 'NOTE: PART A, #9. WE RECOVERED 1.36 BBLS AND DO NOT KNOW IF THE ENTIRE AMOUNT WAS RECOVERED BECAUSE THE LOCATION OF THE RELEASE WAS UNDER THE TANK. THE SITE IS UNDER A CURRENT RWQCB ORDER AND THIS RELEASE IS BEING INVESTIGATED BY THAT AGENCY THEREFORE, IF A BETTER ESTIMATE IS ATTAINED IN THE FUTURE, WE WILL SUPPLEMENT THIS REPORT. 'NOTE: PART E, #6. TANK LEAK DETECTION SYSTEM IS NOT ASSOCIATED WITH THE SCADA SYSTEM.
