Narrative
During a routine inspection of the terminal it was discovered the mixer on tank 3510 was leaking. The mixer was shut off and a technician locked out the shaft on the mixer to stop the leak. The terminal environmental contractor was notified and responded with vacuum trucks and excavation equipment. All free liquids were recovered and placed in a tank onsite. All impacted soil was removed and put into lined roll off boxes for remediation. The mixer seal was replaced. The tank mixer seal release is associated with a specific type of tank mixer installed on several crude tanks at the east houston terminal. Scoping to replace the mixer seals with a third party seal or install seal leak detection on the mixer seal has begun. These modifications are expected to prevent the likelihood of further releases from this type of mixer seal going forward. Supplemental update: part e #6- 9
