Narrative
On november 21, 2017, at 5:15pm, a contract inspector performing an in-service tank inspection at midland station near midland, texas, while working for centurion pipeline, l.P.(cpl), discovered a pinhole leak on the 12'' isolation valve to tank 1966's suction/fill line. The contract employee reported the leak to cpl's station operator, who initiated a prompt and effective response. However, approximately 40 barrels of crude oil leaked into the tank containment berm with all 40 barrels of crude oil later being recovered by vacuum truck and soil remediation. Upon investigation, cpl determined the cause of the leak, located in the 6 o'clock position of the valve body, to be internal corrosion due to the presence of water and microbiologically induced corrosion (mic). Both a visual inspection of the corroded area and lab analysis of the solids removed from the corrosion pits provided the information necessary to determine the cause of the leak. As a result of this leak, cpl identified all other tanks at midland station with similar suction/fill valve configurations, ultrasonically scanned the valves for metal loss, and determined whether valve repairs would be necessary. Further, all similar valve configurations will receive additional biocide treatment no later than february 1, 2018. Additionally, cpl is conducting a study to determine the existence of this incident cause elsewhere in the pipeline system. The result of this study will be communicated in a supplemental report. Supplemental report filed on january 04, 2017: this supplemental report is being filed to make two(2) corrections: 1) on page 2, question 7, the response has been updated to reflect zero members of the general public were evacuated, and 2) on page 7, question 8.A, the response has been updated to reflect that contract personnel working for the operator initially recognized the accident. As noted in the original report, another supplemental report will be filed communicating the results of the accident study. Supplemental final report filed on january 18, 2018: consistent with the narrative above, cpl expanded the study of tanks with similar suction/fill valve configuration to include the remainder of the system. As a result of the study, cpl identified additional tanks with a similar suction/fill configuration. The additional tanks identified will receive the same precautionary measures are the tanks identified at midland station, which includes ultrasonically scanning the valves for metal loss, performing any necessary repairs, and administering additional biocide treatments no later than march 1, 2018. Original final report filed on july 13, 2018: cpl is filing this new original final report at the request of the texas railroad commission (trrc). The initial original report and supplemental reports discussed above were all filed by email with the trrc on an outdated form. This filing is made within the PHMSA website at trrc's request and uses the current form. Since the original report filings were not within the PHMSA system, no report number was generated. Cpl is filing this report as an original report since a supplemental report cannot be filed for this accident in PHMSA's system without a report number. No other changes have been made between the january 18, 2018, supplemental report filing and this filing. Supplemental final report filed on july 27, 2018: this supplemental final report is being filed to correct a6 from 119788 to 1197885.
