Narrative
On 9/17/2018 during a routine station check at approximately 13:30 a 4 bbl release was discovered at tank #9302 by local operations personnel. At approximately 15:12 tx rrc pipeline safety was contacted and incident no. 1839 was assigned. The source of the release was identified as the tank mixer. All released product was contained within the tank dike and additional means of containment were put in place to further reduce environmental impact of release until the tank was isolated and pumped out to a level below the mixer to fully stop the release. All free product was recovered and impacted soil was remediated on site. The mixer unit was removed and will be reinstalled upon repair. Analysis of the failure determined that the mixer motor had become misaligned causing bearing failure which caused the mixer shaft to drop and ultimately caused the failure of the mixer seal. Repaired mixer will be reinstalled and alignment of the motor verified to ensure there is no recurrence.
