The release was located in southwestern Kansas (Stevens County), approximately 6 miles south of Hugoton. The leak was confirmed to be on the Taloga to Liberal interstate pipeline system (Mile post 36.7). No fatalities or injuries occurred as a result of the release and it did not occur in a High Consequence Area (HCA). Evacuations and road closures were not required. The product did not ignite or explode. An estimated 70 barrels of crude oil was released from the underground pipeline on the right of way. Approximately 10 cubic yards of soil were contaminated and remediated but no surface water was affected. The total cost of the accident was estimated as $16,500 including the product lost and repair costs. After the pipeline was shutdown and the upstream mainline valve closed, Jayhawk personnel excavated the pipeline (72 inches deep) and determined by visual inspection that a small hole was located on the bottom of the pipe (6 o’clock position). The external coating on the pipeline was intact. Another pipeline (4 inch in diameter and part of the Anadarko gas pipeline system) was located approximately 21 inches above the Jayhawk line near the area of the leak. At the time of the release, a PHMSA Central Region inspector was performing inspection activities on other Jayhawk Pipeline facilities. This PHMSA inspector was made aware of the release during the inspection and responded to the accident location. Upon cutout of the damaged pipe section, deposits and pitting were observed on the internal pipe surface. Metallurgical analysis of the damaged pipe indicated that “the pipe leaked due to internal corrosion”. The deposits found internal to the pipeline segment were analyzed. Sand and saltwater had collected in a low point in the pipeline resulting in corrosive conditions on the internal pipe surface that led to the development of a pin hole allowing crude oil to be released. System Details The Jayhawk Pipeline system in 2005 contained approximately 700 miles of crude oil pipeline. The system transported crude across Kansas and parts of Nebraska, Oklahoma, and Texas. Jayhawk’s Taloga to Liberal pipeline system runs approximately 80 miles, originating in Morton County, KS and terminating in Meade County, KS. In 2005, Jayhawk moved crude oil from wellhead gathering systems to refineries or tankage. At the accident location, the pipeline was constructed of API 5L Grade B line pipe manufactured in 1958 by Acme Newport. The pipeline was 6.625 inch in diameter with a 0.188 inch wall thickness. The pipe has a seam type of ERW LF (electric resistance welded low frequency) and was coated with AGF-7 (Asphalt-Glass-Felt). The pipeline system was cathodically protected by an impressed current system. There were no service interruptions or supply impacts as a result of the accident. A review of Jayhawk’s leak history records for the 2000-2005 time periods indicated several failures due to internal corrosion. These failures were not limited to line pipe. Several of the identified internal corrosion failures involved station piping. Page 2 of 5 <<>> Failure Investigation Report – Jayhawk Taloga to Liberal Internal Corrosion 04/12/2005 Events Leading up to the Failure The Taloga to Liberal maximum operating pressure (MOP) was 1160 psig as established by hydrostatic test in 2001. The operator initially reported that the operating pressure at the location and time of the failure was 572 psig. The pressure at the time of the failure was later updated and reported to have been approximately 508 psig. Previous maintenance projects relevant to the failure involved ineffective maintenance activities associated with pipeline cleaning. In 1996 a Hazardous Facility Order (CPF No. 36505H) was issued regarding the Jayhawk Pipeline system in response to two failures resulting from internal corrosion occurring between Meade and Chase stations. Jayhawk Pipeline did inject corrosion inhibitor (JaCam 1902C) in this affected pipeline segment prior to this 2005 failure and it was understood that internal corrosion coupons were also in place. Emergency Response The Jayhawk Pipeline control center was notified by the farmer who obtained the phone number from a pipeline marker located in the vicinity of the release. Telephonic notification to the National Response Center was made on April 13, 2005. However, a PHMSA Central Region inspector was already working with the operator at the time of the control center notification. Jayhawk Pipeline personnel were dispatched to the accident site and the pipeline was shut down with manual valve closures. Approximately 10 cubic yards of contaminated soil were remediated. There were no wildlife or water impacts. Long term environmental impact assessment was not required. Summary of Return-to-Service After the field investigation was complete, the damaged pipeline segment was cut out and replaced with pre-tested pipe. Jayhawk Pipeline completed the repair and returned the pipeline to service at a reduced operating pressure approximately 2.5 days after the release. A Corrective Action Order (CAO), CPF 3-2005-5020H, was issued by Central Region on April 26, 2005. This CAO required an MOP pressure reduction from Taloga (MP 12.8) to Liberal (MP 58.8) of 470 psig, quarterly reports providing CAO status updates, metallurgical analysis of the failed pipe, and the submission of a written plan including corrective measures that required an integration of data regarding all integrity threat conditions including a review of previous failure and leak history, ILI testing from Interstate to Meade stations, an evaluation for internal corrosion of all pump stations and breakout tanks in the entire Jayhawk Pipeline system (this included the identification of areas of possible internal corrosion such as dead legs, low spots, areas not subjected to cleaning pig intervals within facilities). The CAO required proposed solutions to internal corrosion with completion schedules for the identified solutions as a result of facility evaluations, repairs, and testing. Since this 2005 failure the frequency of cleaning pigs was increased to weekly runs. Water samples are reported by the operator to be pulled during cleaning pig runs and based on the results, biocide trains are run as necessary. When culture counts increase, the operator reports that trains of biocide and Page 3 of 5 <<>> Failure Investigation Report – Jayhawk Taloga to Liberal Internal Corrosion 04/12/2005 corrosion inhibitor are run with contact time such that microbiological growth can be more effectively controlled. The style, design, wear and manufacturer of the cleaning pigs used are reviewed by the operator to identify possible improvements. Corrosion coupons continue to be monitored. Internal pipeline coating and breakout tank treatments with biocide balls that dissolve or melt on contact with water are ongoing activities. Investigation Details Metallurgical analysis was performed on a 39-inch long segment of the damaged pipe which included the pin hole (approximately 1/8” in diameter) and internal pitted area. Two pits were confirmed through the metallurgical analysis but only one was thru wall. The deposits also found internal to the pipeline segment were sampled and analyzed for composition information. The metallurgical report included information about the deposit samples and stated that “quartz, feldspar, and calcite were from sand that apparently collected in a low spot in the line. A small amount of saltwater also collected at that location and the combination created corrosive conditions that led to the development of the pit responsible for the leak”. Further information provided by the metallurgical report revealed that “the composition of the deposit indicated that acid gasses such as carbon dioxide and hydrogen sulfide had not contributed significantly to the corrosion.” On June 2, 2005, Jayhawk Pipeline completed an in-line inspection (ILI) assessment of the pipeline from Interstate Station to Meade Station as required by the CAO. Jayhawk prepared and implemented a plan to repair the pipeline based on the ILI results. Forty-one sections of pipe were replaced and fifty-six repair sleeves were installed. Following completion of repairs, the Taloga to Liberal pipeline segment was hydrostatically tested in December 2005. On December 20, 2005, the Taloga to Liberal pipeline segment was restarted with the Taloga Station maximum discharge pressure limited to 976 psig. Findings and Contributing Factors Jayhawk Pipeline had several failures due to internal corrosion prior to the accident of April 12, 2005. Prior knowledge of internal corrosion threats did exist for the operator. The Jayhawk Pipeline Taloga to Liberal accident of April 12, 2005 was caused by internal corrosion. Prior to the accident cleaning pigs were not run on a frequent enough basis to prevent accumulation of sand and saltwater at a low point in the pipeline. Sand and saltwater in the low point created corrosive conditions that facilitated the development of corrosion pits on the internal steel pipe surface. One of two corrosion pits identified in the failed segment sent for metallurgical analysis grew until it reached critical depth in the pipe wall and resulted in a pin hole in the pipe that allowed crude oil to be released.
