Incident Narrative

ON FRIDAY, JUNE 2, AT APPROXIMATELY 0826 UPON ARRIVING TO CONDUCT A ROUTINE INSPECTION AND FLUSH OF THE BYPASS LINES OF THE HEATHER GLEN CHECK VALVE (PLMP 25.46 OF L.S. 11 -ROCKLIN TO RENO 6""/8""/10"" PIPELINE), THE KM EMPLOYEE NOTICED A STRONG SMELL OF GASOLINE. WHEN HE OPENED THE METAL VAULT THAT HOUSES THE CHECK VALVE BYPASS VALVE, THE SMELL BECAME STRONGER BUT THERE WAS NO SIGN OF A RELEASE. POTENTIAL RELEASE INTERNAL AND EXTERNAL NOTIFICATIONS WERE MADE (NRC#1180058) AND OES (CONTROL # 17-3870). THE LINE WAS CURRENTLY IN DIESEL. DURING EXPLORATORY EXCAVATION AT APPROXIMATELY 1445, IT WAS DETERMINED THE EXPECTED COSTS OF THE RELEASE COULD MEET 195.52 TELEPHONIC REPORTING CRITERION OF $50,000 (CONFIRMED DISCOVERY), THEREFORE ADDITIONAL NRC (NRC#1180099) AND OES UPDATE CALLS WERE MADE ESTIMATING THE RELEASE AMOUNT TO BE APPROXIMATELY 15 GALLONS. FURTHER EXCAVATION/INVESTIGATION CONCLUDED THE RELEASE WAS COMING FROM THE CHECKVALVE BYPASS SYSTEM'S 3-INCH VALVE STEM SEAL. THE VALVE WAS REPACKED AND THE LEAKING STOPPED. A SUCCESSFUL PRESSURE TEST WAS COMPLETED AND THE LINE WAS PUT BACK INTO OPERATION. THE 48-HOUR PHMSA UPDATE NRC NOTIFICATION (NRC# 1180223) WAS MADE ON JUNE 4 AT 0929 LOCAL TIME CONFIRMING THE INITIAL SPILL VOLUME OF 15 GALLONS. SUBSEQUENT INVESTIGATION BY THE KM REMEDIATION GROUP DETERMINED THE EXTENT OF THE RELEASE TO BE LARGER THAN INITIALLY THOUGHT WITH A RELEASE VOLUME OF 860 GALLONS (20.5 BBLS). SUBSEQUENT SOIL SAMPLING DETERMINED HYDROCARBON CONSTITUENTS OF MULTIPLE PRODUCTS (GASOLINE, DIESEL, AND JET FUEL). 12/13/18- REMEDIATION ACTIVITIES RELATED TO THIS INCIDENT HAVE CONCLUDED AND THEREFORE THE TOTAL COSTS OF REMEDIATION ARE KNOWN AND FINAL AND THEREFORE NECESSITATES THIS SUPPLEMENTAL/FINAL VERSION.
