Narrative
On sunday april 29, 2018, at approximately 4:05 p.M., low pressure was detected by the blue racer midstream ("brm") gas control indicating a leak of over 3 million barrels at the natrium plant ("alarm 1"). This reading was well beyond the pipeline's normal operating volume which ranges between approximately 6,000 and 8,000 barrels per day. The brm gas control operator ("controller") on duty at the time contacted the controllers at the natrium plant ("inlet") and at enterprise to verify the alarm readings. The controller at the inlet stated they were still flowing but pressure had dropped off and the controller at enterprise stated they lost flow and the valve was closed at the moffitt station ("outlet"). Brm controller then contacted field operations supervisor and, out of an abundance of caution, shut in the line until field operations could be deployed and inspect the meters at the inlet. Shortly thereafter at 4:15 p.M., field operators were deployed to the inlet of g-150 to begin verifying the meter reading (source of alarm 1). At around the same time, there was a second leak alarm on the static side of the line at the outlet stating leak volume was 421 trillion barrels - also a reading well beyond the pipeline's normal operating volume ("alarm 2"). Additional field operators were then deployed to the outlet location to verify the meter readings there. The pipeline remained shut in. Field operators then proceeded to inspect, starting at the inlet and outlet locations, and manually close the mainline valves until the cause of the alarms could be determined. At 9:21 p.M., field supervisors called in to brm gas control saying g-150 would remain shut down through the night and that field operators will continue to monitor field pressures and investigate the potential causes of the pressure drop. On monday april 30, 2018, at approximately 7:30 a.M., a contract helicopter was dispatched to overfly the g-150 pipeline. Their flight path began at the north end of the line at the outlet, where they visually inspected the right of way below, and ended at the southern end of the pipeline. At approximately 8:35 a.M., at an approximate location of 39.54497n and -80.40507w, the flight crew discovered evidence of a liquid propane leak in the right of way and, shortly thereafter, communicated the approximate location to the brm regulatory compliance manager. Field operation crews were immediately dispatched to the location to confirm the release and arrived on scene at approximately 9:30 a.M. Upon confirmation of the release, brm employees from field operations, environmental, engineering, and compliance began an initial assessment and determined the release site was in a non-hca and the release did not pose an immediate or potential danger to the surrounding area. Environmental personnel took soil and water samples while field operations continued to monitor the release site. On april 30, 2018, at 9:41 a.M., the regulatory compliance manager notified the nrc pursuant to 49 cfr 195.52(b), being nrc report number 1210711. Subsequently, on may 2, 2018, at 8:39 a.M., within the prescribed 48 hours as prescribed by regulation, a subsequent report was provided to the nrc amending the estimated release volume from "unknown" to "approximately 3,000 barrels", being nrc report number 1210923. There was not a need for evacuations and there were no injuries or property damage reported.
