Narrative
On 11/29/2017 at 15:36 a low lube oil pressure alarm and automatic shutdown was received in the control center on pump unit 43 at lima station. The station operator was notified and investigated the alarm and upon inspection of the unit found gasoline and lube oil mix contained on the pump base. The control center and local supervision were notified of the situation and initial cleanup began while the line remained down. Upon further investigation it was found that the pump seal on unit 43 had failed and would require replacement and the unit was removed from service. An alternate pump unit was available for continued operation of the pipeline which was initially restarted at approximately 19:20 on 11/29/17. At approximately 03:30 on 11/30/2017, local operator personnel discovered that product had migrated further into the facility than initially identified. Control center was notified and the line was shut down again while additional investigation and cleanup efforts began. To eliminate the possibility of a problem with the discharge piping a static pressure test was performed on the piping outside the pump and motor units. The results of the static test were acceptable and the line was restarted again at approximately 20:10 on 11/30/17 with the alternate pump unit. It was determined that the additional volume released also came from the original failure of the pump seal on unit 43. Final estimated volume released was 8 barrels. Due to the additional product released, the migration of it within the facility and additional cleanup costs it was determined at approximately 10:00 on 11/30/17 that total costs for the release would exceed $50,000 and the nrc was notified at 10:59. Report no. 1198416 was issued. Required 48 hour follow up to nrc was made on 12/1/17 and report no. 1198568 was issued. Pump unit 43 was inspected and it was determined that the shaft bearing had worn enough to allow it to shift towards the outboard seal which initiall compromised the seal. The compromised seal allowed the lube oil for the motor to escape and also mix with shipped product (gasoline) causing inefficient lubrication of the unit which further exacerbated the seal to failure and ultimately caused the low pressure alarm of the lube oil system and shut down of the pump unit that initially alerted operations of the release. Unit 43 will be fully inspected and repaired prior to returning it to service. Alternate pump units at lima have been inspected for similar wear with no additional problems identified.
