Narrative
On 4/25/2019 at approximately 13:00, aerial patrol was flying the 20" wortham to longview segment and noted crude oil on the ground at leagueville station. The pilot notified field personnel. Upon arrival on site field personnel noted approximately 2 bbls of crude oil out at the pump location and notified control center immediately. The pipeline was shutdown at 13:30. Upon investigation, the inboard seal on the mainline pump had failed due to an unknown cause. Additionally, a faulty connection was discovered on the seal pot alarm. Under normal circumstances the seal pot would alarm and pump would shut down automatically. The faulty connection to the seal pot alarm allowed the pump to continue running and excess crude oil to be released from the pump seal area. The seal pot alarm was repaired and the pump seal was replaced. All free product was recovered and contaminated soil is being remediated onsite. Other mainline pump unit at leagueville was inspected for pump seal and seal pot alarm issues and none were found. Upon replacement of the seal and repair of the seal pot alarm, control center was notified at 15:30 to restart the line. Area was visually monitored to assure normal startup and no to verify no additional issues existed.
