Page 1Official PDFFailure Investigation Report – Buckeye Tank 701 Line Failure – Activity ID 128252 Principal Investigator Chris D’Souza Regional Director Byron Coy Date of Report 03/14/2011 Subject Failure Investigation Report – Buckeye Tank 701 Line Failure Summary: On December 30, 2009 @ 22:40 hrs Buckeye called the NRC to report a gasoline leak from a line connected to Storage Tank 701 (Appendix 4 – NRC Report 927442). Residents from Clear View Lane numbers 2250 and 2290 reported odors in their homes on December 29, 2009 @ 21:12 hrs. This was initially reported on NRC# 927364 (Appendix 3). Residents from four homes on Clear View Lane were evacuated by the Fire Department as a precautionary measure. The odors were emanating from the sewer line in those homes and from sewer vents on the street. The location of the leak on the pipe was below grade on the underside of the single pipe connection to and from Tank # 701, below a valve manifold along the inside of Buckeye’s fence line on Cherry Road (Appendix 1 - Map). The leak in the pipe occurred as a result of external corrosion. Gasoline product migrated below grade to the outside of the property fence line where it entered a breach in a nearby sewage line on Cherry Tree Road. After the discovery of the leak, the tank line was drained, the coating peeled back and the integrity of the pipe was good enough to install a temporary “Plidco” sleeve. The line was pressure tested to 128 psig on January 1, 2010, and did not leak. After the pressure test, product transfer resumed, using the temporarily repaired line, for approximately 6 hrs without additional leaks. A trench, approximately 5 feet deep was dug between the repaired line and fence line to mitigate product plume migration. Three monitoring wells (PZ1/ PZ2 / PZ3), 15 feet deep were installed along the line directly between the failed line and fence line to monitor product. Initial product depth in PZ2 & PZ3 was about 2ft in the wells. PZ1 showed no product. The water table is approximately 8-10 feet. Additional monitoring wells are planned to delineate product plume. One monitoring hole was dug up on the residential side of Cherry Tree Road to check for any product – no product was found and the hole was filled. Approximately 386 barrels of gasoline was spilled. Fifty-two barrels were recovered. (Appendix 5 - Photos) Buckeye HL NJ 2009-12-30.docx Page 1 of 3#

Page 3Failure Investigation Report – Buckeye Tank 701 Line Failure – Activity ID 128252 System Details Chelsea Tank Farm - 12 Breakout tanks and associated piping Events Leading up to the Failure Buckeye Partners’ (Buckeye) control center in Breinigsville, PA received a call from the Aston, PA Fire Marshall reporting gasoline odors in the area of Clearview Lane in Aston, PA (Appendix 1 - Map). Buckeye’s 8” pipeline in the area (CT553JP) had been shut down earlier in the day as part of a normal, scheduled shut down and the pipeline pressure was being monitored. A detailed timeline of events can be found in Appendix 6 of this report. Emergency Response After notification from Buckeye‘s control center, field personnel arrived at the site and confirmed the presence of gasoline odors. A representative of the Pennsylvania Department of Environmental Protection (PADEP) measured gas odors in several adjacent sanitary sewer manholes as well as a few nearby residences. The fire department requested the evacuation of four residences as a precaution until the vapor levels subsided. A unified command was established by Buckeye’s local operations manager. Buckeye personnel proceeded to walk the pipeline right of way and although no visible product was seen, they did detect an odor in some areas. Buckeye decided to walk the pipeline right of way again during daylight hours and to dig test holes in the areas of high vapor levels. Buckeye had a total of ten locations probed between Cherry Tree Street and Overlook Street with no product found. The test holes dug on Arbor Lane were also found to be clean of product. The PADEP representative indicated that it appeared that the problem was in the vicinity of Scott Lane because the sewer manholes on Cherry Tree Street and Frazer Street had high vapor levels. Buckeye decided to excavate the gasoline tank lines inside the adjacent Chelsea station since these pipelines were closer to Scott Street. Buckeye personnel identified high vapor levels and visible product in the excavation at the tank junction valves in Chelsea station. The release was determined to be on the tank 701 line. Buckeye installed a Plidco sleeve, which stopped the release. Summary of initial start-up plan and return-to-service, including preliminary safety measures A temporary “Plidco” sleeve was installed on the line. The line was pressure tested to 128 psig on January 1, 2010, and did not leak. After the pressure test, product transfer resumed, using the temporarily repaired line, for approximately 6 hrs without additional leaks. An accident report was submitted by Buckeye pertaining to this event (Appendix 2). Permanent repairs were completed on February 12, 2010 by cutting out the damaged pipe and replacing it with certified pipe. The damaged pipe was sent to a laboratory for metallurgical analysis. The analysis revealed the cause of the external corrosion to be microbiological induced corrosion. Remediation is still on-going. Operation of the facility was turned over to Conoco Phillips on March 1, 2011. Additional follow-up on the contributing factors for this accident will be identified and managed by Conoco Phillips. Investigation Findings & Contributing Factors The cause has been determined to be external microbiological induced corrosion. The corrosion appears to be limited to the section of piping where the failure occurred.

BUCKEYE’S 8” PIPELINE IN THE AREA (CT553JP) HAD BEEN SHUT DOWN EARLIER IN THE DAY AS PART OF A NORMAL, 5 5 of 6#

Page 12128252 Appendix 2 Accident Report 20090367 - 13086 SCHEDULED SHUT DOWN AND THE PIPELINE PRESSURE WAS BEING MONITORED. AFTER NOTIFICATION FROM BUCKEYE‘S CONTROL CENTER, FIELD PERSONNEL ARRIVED AT THE SITE AND CONFIRMED THE PRESENCE OF GASOLINE ODORS. AT 12:45 A.M. ON DECEMBER 30, 2009, A REPRESENTATIVE OF THE PENNSYLVANIA DEPARTMENT OF ENVIRONMENTAL PROTECTION (PADEP) MEASURED GAS ODORS IN SEVERAL ADJACENT SANITARY SEWER MANHOLES AS WELL AS A FEW NEARBY RESIDENCES. THE FIRE DEPARTMENT REQUESTED THE EVACUATION OF FOUR RESIDENCES AS A PRECAUTION UNTIL THE VAPOR LEVELS SUBSIDED. AT 1:40 A.M. ON DECEMBER 30, 2009 A UNIFIED COMMAND WAS ESTABLISHED BY BUCKEYE’S LOCAL OPERATIONS MANAGER. BUCKEYE PERSONNEL PROCEEDED TO WALK THE PIPELINE RIGHT OF WAY AND ALTHOUGH NO VISIBLE PRODUCT WAS SEEN, THEY DID DETECT AN ODOR IN SOME AREAS. BUCKEYE DECIDED TO WALK THE PIPELINE RIGHT OF WAY AGAIN DURING DAYLIGHT HOURS AND TO DIG TEST HOLES IN THE AREAS OF HIGH VAPOR LEVELS. BY NOON ON DECEMBER 30, 2009, BUCKEYE HAD A TOTAL OF TEN LOCATIONS PROBED BETWEEN CHERRY TREE STREET AND OVERLOOK STREET WITH NO PRODUCT FOUND. THE TEST HOLES DUG ON ARBOR LANE WERE ALSO FOUND TO BE CLEAN OF PRODUCT. AT 12:28 P.M. ON DECEMBER 30, 2009, THE PADEP REPRESENTATIVE INDICATED THAT IT APPEARED THAT THE PROBLEM WAS IN THE VICINITY OF SCOTT LANE BECAUSE THE SEWER MANHOLES ON CHERRY TREE STREET AND FRAZER STREET HAD HIGH VAPOR LEVELS. BUCKEYE DECIDED TO EXCAVATE THE GASOLINE TANK LINES INSIDE THE ADJACENT CHELSEA STATION SINCE THESE PIPELINES WERE CLOSER TO SCOTT STREET. AT 10:00 P.M. ON DECEMBER 30, 2009 BUCKEYE PERSONNEL IDENTIFIED HIGH VAPOR LEVELS AND VISIBLE PRODUCT IN THE EXCAVATION AT THE TANK JUNCTION VALVES IN CHELSEA STATION. THE RELEASE WAS DETERMINED TO BE ON THE TANK 701 LINE. AT 1:30 A.M. ON DECEMBER 31, 2009, BUCKEYE INSTALLED A PLIDCO SLEEVE, WHICH STOPPED THE RELEASE. AT NOON ON DECEMBER 31, 2009, ALL RESIDENTS WERE CLEARED TO SAFELY RETURN TO THEIR HOMES. ON JANUARY 1, 2010, THE LOCAL SEWER AUTHORITY CONFIRMED AT LEAST THREE BREACHES IN THE SANITARY SEWER LINE LOCATED UNDER CHERRY TREE STREET. THESE BREACHES ALLOWED GASOLINE FROM THE RELEASE TO GET INTO THE SANITARY SEWER SYSTEM. THE LOCAL SEWER AUTHORITY IS PRESENTLY IN THE PROCESS OF REPAIRING THE SEWER SYSTEM IN THIS AREA. BUCKEYE CONTINUES TO MONITOR THE PLIDCO SLEEVE TWICE DAILY UNTIL PERMANENT REPAIRS CAN BE COMPLETED, WHICH IS SCHEDULED FOR THE WEEK OF FEBRUARY 8, 2010. BUCKEYE HAS DUG NUMEROUS TEST WELLS AND CONTINUES TO WORK ON BOTH THE REMEDIATION OF THE RELEASE AND DETERMINING THE ESTIMATED VOLUME. BUCKEYE NOTIFIED ALL APPROPRIATE OUTSIDE AGENCIES OF THIS INCIDENT. PERMANENT REPAIRS WERE COMPLETED ON FEBRUARY 12, 2010 BY CUTTING OUT THE DAMAGED PIPE AND REPLACING IT WITH CERTIFIED PIPE. THE DAMAGED PIPE HAS BEEN SENT TO A LABORATORY FOR METALLURGICAL ANALYSIS. METALLURGICAL ANALYSIS REVEALED THE CAUSE OF THE EXTERNAL CORROSION TO BE MICROBIOLOGICALLY INDUCED CORROSION. REMEDIATION IS STILL ON-GOING. OPERATION OF THE FACILITY WAS TURNED OVER TO CONOCOPHILLIPS ON 3-1-11. 6 6 of 6#

Page 22128252 Appendix 6 Accident Report 20090367 Timeline of Events Date Time Event 12/29/2009 22:00 Buckeye Partners’ (Buckeye) control center in Breinigsville, PA received a call from the Aston, PA Fire Marshall reporting gasoline odors in the area of Clearview lane in Aston, PA. Buckeye’s 8” pipeline in the area (CT553JP) had been shut down earlier in the day as part of a normal, scheduled shut down and the pipeline pressure was being monitored. After notification from Buckeye‘s control center, field personnel arrived at the site and confirmed the presence of gasoline odors. 12/30/2009 12:45 A representative of the Pennsylvania Department Of Environmental Protection (PADEP) measured gas odors in several adjacent sanitary sewer manholes as well as a few nearby residences. The fire department requested the evacuation of four residences as a precaution until the vapor levels subsided. 12/30/2009 1:40 A unified command was established by buckeye’s local operations manager. Buckeye personnel proceeded to walk the pipeline right of way and although no visible product was seen, they did detect an odor in some areas. Buckeye decided to walk the pipeline right of way again during daylight hours and to dig test holes in the areas of high vapor levels. 12/30/2009 12:00 Buckeye had a total of ten locations probed between Cherry Tree street and Overlook street with no product found. The test holes dug on arbor lane were also found to be clean of product. 12/30/2009 12:28 The PADEP representative indicated that it appeared that the problem was in the vicinity of Scott lane because the sewer manholes on Cherry Tree street and Frazer street had high vapor levels. Buckeye decided to excavate the gasoline tank lines inside the adjacent Chelsea station since these pipelines were closer to Scott street. 12/30/2009 22:00 Buckeye personnel identified high vapor levels and visible product in the excavation at the tank junction valves in Chelsea station. The release was determined to be on the tank 701 line. 12/31/2009 1:30 Buckeye installed a Plidco sleeve, which stopped the release. 12/31/2009 12:00 All residents were cleared to safely return to their homes. 1/1/2010 The local sewer authority confirmed at least three breaches in the sanitary sewer line located under cherry tree street. These breaches allowed gasoline from the release to get into the sanitary sewer system. The local sewer authority is presently in the process of repairing the sewer system in this area. Buckeye continues to monitor the Plidco sleeve twice daily 2/8/2010 Buckeye has dug numerous test wells and continues to work on both the remediation of the release and determining the estimated volume. Buckeye notified all appropriate outside agencies of this incident. 2/12/2010 Permanent repairs were completed by cutting out the damaged pipe and replacing it with certified pipe. The damaged pipe has been sent to a laboratory for metallurgical analysis. Metallurgical analysis revealed the cause of the external corrosion to be microbiologically induced corrosion. Remediation is continuing. 3/1/2011 Operation of the facility was turned over to ConocoPhillips. 1 of 1#
