Narrative
Sep. 1, 2017, during the investigation of a non related rttm leak detection alarm, scada personnel shut down wr-01 pipeline from ponca city, ok to glenpool, ok to perform a stand-up integrity test. The segment from mp 52 to mp 72 was determined to be a suspect of a leak and pressure was added to assist in integrity verification. Upon re-pressurization of the segment, similar pressure loss was observed. Historical data was reviewed and line flyer was engaged for over flight the following morning. On 9-2-2017 at app. 09:00, line flyer reported dead vegetation near mp 56. Field personnel arrived on site at app. 09:45 and began response and clean-up activities. Pipeline was already shutdown and the downstream valves were then opened to relieve pressure. Upon excavation, an external corrosion through-wall feature was discovered. 9-3-2017, plidco clamp was installed and successfully passed pressure test. Pipeline was restarted for normal operation at app. 16:20. Preliminary visual field inspection indicates external corrosion. This will be verified via metallurgical analysis when failed segment is eventually removed. Target date for cutout is 10-17-2017 part a, item 4 "local time and date of incident" is listed as 7-13-2017. This date was determined based on information gathered during the investigation. 2018-2-8 update: updated part "d", section 8 with new cost information. Updated part "e", section 9 with control center investigation information. Updated part "g", cause information due to receipt of metallurgical analysis report. 2018-7-10 update: updated part "a", section 11 with estimated volume recovered based on information received on 6-19-2018 2018-11-1 update: updated part "a", section 11 with estimated volume recovered based on information received on 10-24-2018. Updated part "d", section 8e with remediation costs to date based on information received 10-31-2018. 2018-11-27 update: updated part "g", section 15a with corrected historical tool run information. 2019-04-01 update: updated part a, item #11 with amount recovered. Updated part d, item #8e with current costs for environmental remediation. Update reported status to "final". Site remediation is currently and will remain under the supervision of the oklahoma corporation commission.
