Narrative
The p66 gold line received notification of an odor in the vicinity of mp 670(south st. Louis) on 10/23/18. The line was shut down due to scheduling requirements prior to the odor notification. On 10/25 successful stand-up pressure tests were conducted on the gold and blue lines, which share a r-o-w. Small ground holes were probed, air samples retrieved and line records were reviewed to determine a possible source of the odor. Line file checks and information from phillips66 retirees revealed three weld+end repair sleeves were on the line and buried in the area exhibiting elevated lel readings and containing benzene. The area was excavated. The three repair sleeves were mag particled with one revealing a potential crack. 86' of pipe, containing all three repair sleeves, was cut out and replaced. Contaminated soil was removed and properly disposed. The cracked sleeve was sent for a lab analysis. The line resumed operation at 21:04 11/3/18. 1/30/19 - update information - further investigation has revealed: (1) lab analysis indicates the suspect weld+end is not cracked. (2) multiple field tests indicate line integrity is intact. (3) lab soil sample analysis indicates a very small quantity of product present. The phillips 66 remediation group continues to investigate the source of this release and may never know the true source. P66 will finalize this report and if any new information comes forth, we will update this report at that time. Third party sources are being considered. Based on soil sample lab analysis and other applicable data, p66 calculates the approximate release volume to be 43.2 gallons. 2/15/19 update - at the request of brian pierzina, changes were made to this form including: (1) multiple event times and dates. (2) part g "apparent cause" was changed to "equipment failure" though numerous field and lab efforts have been unable to reveal a source for the release. (3) line shut-down data: initial shutdown of the line was due to operational scheduling, but remained down after the odor complaint was received apx 75 minutes later.
