Narrative
Updated 01/21/2019: at approximately 23:30 on 10/29/2018, pipeline tech discovered oil leaking from the top of prover during proving operations at the texas city cms pump station. The prover was isolated and the station was not shut down. Cleanup and remediation began immediately. The original nrc is #1228885 and the 48 hour update nrc is #1228936. On 10/31/2018 the prover was evaluated by a third party and it was determined that the shaft was broken internally, which caused the seal to fail inside the prover. Internal parts were replaced during the prover repair and the prover was returned to service on 11/28/2018. Incidents are tracked and trended so enterprise can take action to prevent recurrence.
