Narrative
On october 25, 2023, at approximately 11:05 am cst, a centurion pipeline, l.P. (cpl) employee discovered a leak in cpl's midland station near midland, texas. Cpl determined the source of the leak to be a station sump and promptly isolated the leak. Thirty-six (36) barrels of crude oil was released and was contained completely on-site. The contaminated soil will be remediated on-site. No injuries, fatalities or fires were associated with this incident. Cpl reported the leak to the texas railroad commission, office of pipeline safety at 12:05 pm cst on october 25, 2023. Associated incident # is 2939. A notification to the national response center (nrc) was not required but made on october 25, 2023 at 12:00 cst. Associated nrc# for the initial call was 1382630. An updated 48-hour notification was made on october 27, 2023 at 8:05 am cst. Associated nrc# is 1382782. The system was operational at 12:30 pm cst but was not restarted until the 5:44 pm cst. At the time of this writing, no repairs were required and the root cause failure analysis will be completed and the resulting information submitted via supplemental report(s). Supplemental report filed on march 13, 2024: during the root cause analysis, cpl determined that the associated pump had a setting to the debounce timer that was not set to the atypical setting for the associated pump. There is no preset requirement for the debounce timer but increased duration of the debounce timer would allow for greater flexibility in the system to recover and allow for proper mitigative actions by operations personnel.
