Incident Narrative

1/13/20 SUPPLEMENT: CORRECTED PART A #5 LOCATION OF ACCIDENT. ON TUESDAY, 12/10/2019, AT APPROXIMATELY 1808 (PACIFIC), A RELEASE OF DIESEL FUEL OCCURRED DURING THE COMMISSIONING OF A PCV (PRESSURE CONTROL VALVE) REPLACEMENT PROJECT. DURING THE MAINLINE PUMP STARTUP OF UNIT #3, THE 3/8-INCH TUBING (CONNECTING THE PRESSURE TRANSMITTER TO THE 24"" PCV) CAME APART RESULTING IN A 13.9 GALLON DIESEL RELEASE. THE WORK WAS BEING DONE BY A SECOND PARTY CONTRACTOR. AT THE TIME OF THE RELEASE, KM OPERATIONS PERSONNEL, USING VERY CONSERVATIVE MEASUREMENTS, ESTIMATED A 257-GALLON VOLUME AND REPORTED VIA OUR IMMEDIATE ""CALIFORNIA NOTIFICATIONS"" PROCEDURE (OES #19-7886 AND NRC#1266060). THE FOLLOWING DAY (DURING DAYLIGHT), THE VOLUME WAS RECALCULATED USING ACTUAL MEASUREMENTS BACKED UP BY ENGINEERING CALCULATIONS TO CALCULATE THE ACTUAL 13.9 GALLON VOLUME. THE AGENCY NOTIFICATIONS WERE SUBSEQUENTLY UPDATED WITH THE ACTUAL RELEASE VOLUME (OES#19-7886 UPDATED ON 12/11 @ 1329 AND NEW NRC#1266145). THIS RELEASE DID NOT MEET THE REQUIREMENTS OF IMMEDIATE NOTICE PER 195.52. THE RELEASE WAS PROMPTLY STOPPED, CLEANED UP PROPERLY BY LOCAL OPERATIONS WHILE TWO CONTRACTOR EMPLOYEES WERE SENT FOR DOT POST ACCIDENT TESTS AND ONE'S OQS REVOKED. SUBSEQUENT INVESTIGATION DETERMINED THE CAUSE OF THE RELEASE TO BE AN INCORRECTLY INSTALLED SWAGELOK FITTING.
