Amendment No. 2 sets forth further preliminary findings based on PHMSA's continuing oversight of BP's compliance with the March 15, 2006 CAO, and the results of recent testing and inspections of the subject lines. Amendment No. 2 imposes additional monitoring, testing, and information requirements and prescribes standards and deadlines for the repair of pipeline defects. The Amendment also imposes new requirements arising out of BP's decision to suspend or terminate operations involving one or more of its pipelines segments. Except as expressly provided in Additional Preliminary Finding No. 16, Amendment No. 2 does not waive, alter or supplant the original terms and requirements of the July 20,2006 Amendment No. 1 to the CAO or the March 15,2006 CAO. Your receipt of the enclosed document constitutes service of that document under 49 C.F.R. 8 190.5. The terms and conditions of this Amendment are effective upon receipt. Sincerely, Acting Associate Administrator for Pipeline Safety Enclosure cc: Chris Hoidal, P,E., Director Western Region, PHMSA AUG-09-2006 23:21 PHMSA AK DIST OFFICE DEPARTMENT OF TRANSPORTATION PIPELINE AND HAZARDOUS MATERIALS SAFETY ADMINISTRATION OFFICE OF PIPELINE SAFETY WASHINGTON, DC 20590 In the Matter of BP Exploration (Alaska) Inc., ) CPF No. 5-2006-5015H Respondent AMENDMENT No. 2 TO CORRECTIVE ACTION ORDER Background & Purpose On March 15,2006, under authority of 49 U.S.C. 5 601 12, the Associate Administrator for Pipeline Safety, Pipeline and Hazardous Materials Safety Administration (PHMSA), issued a Corrective Action Order (CAO) to BP Exploration (Alaska), Inc., @P), finding that the continued operation of three crude oil transmission pipelines in BP's Prudhoe Bay Operating Area -the Western Operating Area (WOA), Eastern Operating Area (EOA) and Lisburne crude oil pipelines - would be hazardous to life, property, or the environment without the implementation of corrective measures. The CAO was issued in response to a failure on BP's WOA pipeline that caused the discharge of an estimated 20 1,000 gallons of crude oil. In addition to addressing the immediate consequences of the pipeline failure, the March 15,2006 CAO required BP to take various measures to evaluate the condition of the subject Iines, and to make any necessary repairs. Items 3,4, and 7 of the CAO required BP to perform cleaning operations on the three pipelines, assess the condition of the pipeline walls, and measure any corrosion or other defects using an instrumented in-line inspection tool (known as a "smart-pig"). On July 20,2006, under authority of 49 U.S.C. $601 12, the Associate Administrator issued Amendment No. 1 to the March 15,2006 CAO. Amendment No. 1 set forth additional preliminary findings based on PHMSA's oversight of BP3s activities and PHMSAYs continuing investigation of pipeline conditions on BP's Prudhoe Bay Operating Area. Amendment No. 1 required BP to perform additional integrity assessments and to develop and implement plans for addressing new and ongoing safety risks associated with its failure to complete diagnostic measures required by Items 3,4, and 7 of the March 15,2006 CAO. QUG-09-2006 23:22 PHMSQ QK DIST OFFICE P. 04 Additional Preliminary Findings Prudhoe Bay EOA Transmission Pipeline 1. The EOA pipeline is constructed of X60 Grade, 0.344-inch wall thickness pipe manufactured between 1976 and 1979. The fust segment of the EOA pipeline, extending approximately three (3) miles from Flow Station 2 (FS2) to Flow Station 1 (FS l), is constructed of 30-inch nominal diameter pipe. The second segment, constructed of 34- inch nominal diameter pipe, extends approximately five (5) miles fiom FS 1 to Skid 50; just upstream of the Trans Alaska Pipeline System (TAPS). 2. On or about July 22,2006,3 7 days after the deadline established under the March 1 5, 2006 CAO (as extended), BP performed smart pigging of the FS2-FS1 segment of the EOA pipeline. BP reportedly received initial reports of the smart pig data on August 4, 2006. 3. These reports identified sixteen (16) anomalies (representing wall loss in excess of 70 percent, including two (2) over 80 percent) at twelve (1 2) separate areas on the FS2-FS 1 segment of EOA pipeline. According to BP, the data indicated each of the sixteen anomalies is approximately 1.5 by 1.5 inches in size and is located in the lower quadrant of the pipe (between the 5:45 to 6:45 positions). 4. On or about August 5,2006, BP began performing direct visual and ultrasonic inspection of the locations identified by the smart-pig data as having significant wall loss. In the course of that work, according to BP reports, BP discovered a location where crude oil apparently had leaked through the pipe wall and onto the insulation material. On the basis of that discovery, BP reportedly initiated shut down of the FS2-FS 1 segment of thc EOA pipeline at approximately 6:00 a.m. on August 6,2006. 5. Later in the morning of August 6,2006, according to BP, BP personnel discovered crude oil leaking from a different location on the FS2-FS 1 segment of the EOA pipeline. According to BP, field inspection of the leak site revealed multiple holes in the pipe wall at a single location, contributing to an estimated spill of approximately five (5) barrels of processed crude oil. 6. Since August 6,2006, BP reportedly has discovered pinhole leaks on at least four additional locations on the FS2-FS 1 segment of the EOA pipeline. 7. On the afternoon of August 6,2006, BP notified the Director of PMSA's Western Region Pipeline Safety Ofice of the EOA pipeline spill and advised PHMSA that BP had decided to shut down all of its Prudhoe Bay production fields on the North Slope. BP further stated that the Lisburne pipeline and associated production facilities would remain in service. On August 8,2006, BP indicated its desire to maintain operations of the WOA pipeline if pipeline integrity could be demonstrated through further field assessments. RUG-89-2086 23:22 PHMSR QK DIST OFFICE P. 85 8. To date, BP has not performed cleaning or smart pigging operations on the FS 1-Skid 50 (34-inch diameter) segment of the EOA pipeline. 9. On or about August 7,2006, a team of PHMSA personnel and officials were deployed to BP facilities in Alaska to investigate the August 6,2006 spill, examine the basis for BP's decision to cease operations, oversee BP's shutting down of pipeline operations, and evaluate what procedures would be necessary to safely restart operations. 10. On August 9,2006, BP announced that it had decided to replace the FS2-FSI segment and that BP had no plans to return the segment to operation. Pmdhoe Bav Lisburne Transmission Pipeline 11. On or about June 30,2006, fifteen (15) days after the deadline established under the March 15,2006 CAO (as extended), BP performed smart pigging of the Lisbume pipeline. BP reportedly received initial reports of the smart pig data on or about July 13, 2006. 12. BP reports that smart-pigging data indicate ten (10) areas in which external wall loss exceeded 40 percent. Prudhoe Bay WOA Transmission Pipeline 13, The WOA pipeline consists of two segments of 34-inch nominal diameter pipe. The first segment (OT-2 1) extends approximately three (3) miles from Gathering Center 2 (GC2) to Gathering Center 1 (GCI). The OT-21 segment is currently bypassed by a jumper pipeline (GHX21). The second, downstream segment extends approximately fivc (5) miles from GC1 to Skid 50, and then to Pump Station 1 (PSI), just upstream of TAPS. 14. To date, BP has not performed cleaning or smart-pigging operations on either segment of the WOA pipeline. 15. BP took the OT-21 segment out of service following the spill discovered March 2,2006 and has not returned the line to service since that date. Pursuant to Item 16 of Amendment No. 1 to the March 15,2006 CAO, BP has submitted a plan for de-oiling the OT-21 segment beginning on or before August 22,2006. The Director of the Western Region Pipeline Safety Office has reviewed and concurs with the plan. 16. BP has advised PHMSA by letter dated July 28,2006, that the OT-21 segment will not be returned to service and will be permanently replaced with a new pipeline. To the extent that OT-2 1 will not be returned to service and is deoiled, BP is not required to complete smart-pigging of that segment as otherwise required by the March 15,2006 CAO. 17. On June 6,2006, BP submitted a plan for conducting assessment of pipeline wall integrity using ultrasonic testing (UT) to measure the thickness of the pipe wall at particular points on the line. BP proposed to use this inspection method until it conducts 3 PHMSR RK DIST OFFICE smart pigging as required by the March 15,2006 CAO, and interprets the results. BP contended that by extrapolation from the UT data, BP could obtain information, of equivalent reliability to smart pig results, for understanding the pattern and extent of internal corrosion in its pipelines. BP submitted the results of ultrasonic testing, performed from March through July, 2006, on the GC1-Skid 50 segment of the WOA pipeline. 18. Following the recent discovery of leaks and internal corrosion on the EOA line, BP announced a plan to conduct more thorough,continuous automatic UT testing (AUT) of the in-service segment of its WOA pipeline. As of August 9,2006, BP reportedly had initiated AUT testing on the GC1-Skid 50 segment. 19. As of August 8,2006, BP has advised PHMSA investigators that a11 available resources are being deployed for completing inspection of the in-service segment of the WOA pipeline as soon as possible. BP representatives have advised PHMSA investigators and officials that they have deployed all available equipment and resources in support of completing continuous AUT testing as soon as possible. At the same time, BP reports that it is moving ahead with plans to smart pig all or part of the WOA pipeline by acquiring equipment and planning preliminary operations. 20. PHMSA has not ordered BP to cease operating the GC1-Skid 50 segment or the OT21 bypass (CHX21) of the WOA pipeline, and PHMSA is not aware of any data concerning the current condition of pipe on the GC1 -Skid 50 segment, or the GHX21 bypass, that would necessitate an immediate cessation of operations on the WOA pipeline in order to protect life, property, or the environment. DETERMINATION OF NECESSITY FOR AMENDMIENT OF COWCTIVE ACTION ORDER AND RIGHT TO A HEARING Section 601 12 of Title.49, United States Code, provides for the issuance of a Corrective Action Order, after reasonable notice and the opportunity for a hearing, when PHMSA decides that a pipeline facility is hazardous. Corrective action may include the suspended or restricted use of a pipeline facility, physical inspection, testing, repair, replacement or other appropriate action. The basis for deciding that a pipeline facility is hazardous, requiring corrective action, is set forth both in the above-referenced statute and 49 C.F.R. 5 190.233. Section 601 12(e) of Title 49, United States Code, and the regulations promulgated thereunder (49 C.F.R. $190.233(b)), provide for the issuance of a Corrective Action Order without prior opportunity for notice and hearing upon a finding that a failure to issue the Order expeditiously will likely result in serious harm to life, property, or the environment. In such cases, an opportunity for a hearing will be provided as soon as practicable after the issuance of the Order. Based on the additional preliminary findings set forth above and the preliminary findings in the March 15,2006 CAO and Amendment No. 1, I continue to find that the presence of hazardous conditions on the EOA, Lisburne, and WOA pipelines, without the implementation of corrective measures, would result in likely serious harm to property or the environment. Additionally, after considering the circumstances surrounding the failures discovered on August 6 and March 2,2006, the number and severity of anomalies discovered on the EOA line, the immediate proximity of the pipeline to environmentally sensitive areas, and the safety and environmental threats posed by serious internal corrosion of the EOA line, I find that failure to expeditiously issue this Amendment would result in likely serious harm to life, property and the environment. Within ten (10) days of receipt of this Order, BP may request a hearing, to be held as soon as practicable, by notifying the Associate Administrator for Pipeline Safety in writing, delivered personally, by mail or by facsimile at (202) 366-3666. A hearing, if requested, will be held in Lakewood, Colorado or Washington, DC on a date that is mutually convenient to PHMSA and BP. A hearing requested on this Amendment may be consolidated with the hearing BP has already requested on this CAO. In the course of this investigation, PWSA may identifjr additional measures that need to be taken to ensure the safety of BP's pipeIines covered by the CAO. The terms of the March 15, 2006 CAO and the additional terms added by Amendment No. 1, this amendment, and subsequent amendrnent(s) will remain in place for as long as the Associate Administrator deems necessary to ensure the subject pipelines are operated in a safe and environmentally sound manner. The actions required by this CAO are in addition to and do not waive or modify any requirements that apply to BP's pipeline systems under any provision of Federal or state law, or under any other order issued to BP under authority of 49 U.S.C. ĦħĦħ60101 et seq.
