Narrative
At 20:19 on 4/24/19, operations control initiated pipeline shutdown and isolation based on scada and the cpm system indications and alarming. Code red procedures were declared at 20:26 initiating a full emergency response. Mainline remotely operated valves were closed and resources were dispatched to the area to close manual valves and begin leak investigation and response. Psaps (public access safety point) for lyon county and yellow medicine county were notified. The nrc was notified with initial report #1243669. The nrc was subsequently updated with additional reports #1243843 on 4/26/19 12:57 and #1243857 on 4/26/19 15:09. Communications between magellan personnel and county emergency dispatch and local fire departments were conducted throughout the investigation and response activities. The release was discovered in an intentional pipe exposure spanning a drainage outfall ditch. At 22:30 on 4/24/19, a temporary leak clamp was installed on the pipe, thus stopping the release. County road 18 and county section line roads near the drainage ditch were closed. Containment booms were deployed along the drainage channel at five strategic locations downstream of the release site. Skimmers, vacuum trucks, and sorbent materials were used to recover and collect product. Impacted soils were excavated and stockpiled for proper disposal. Magellan personnel and contractor resources performed product recovery and monitoring activities continuously until the end of the day on 4/26/19. Road closures were reopened by the end of the day on 4/26/19. Ground patrolling in combination with drone fly overs were conducted along the 10 mile length of the drainage ditch from the release site to the last set of containment booms to identify sheen or product. Personnel provided overnight and next-day monitoring of select boom sites in anticipation of forecasted rain/snow events. No significant sheen was identified during and up to the six hours after the end of the precipitation event. The release appears to have originated from a bullet hole in the pipe body. After drain up activities were completed on the pipeline, the damaged pipe section was removed and replaced with a new pre-tested pipe section. Pipeline repairs were completed on 4/26/19 and the pipeline was placed back in service on 4/27/19. The damaged pipe section is currently in the custody of the lyons county sherriff's office.
