Point Source(s) Notes Amount of Release

South railcar unloading rack from Railcar No. MOBX26060
Cause: An operator attempted to collect a routine product quality sample from a hose connected to the belly of the railcar valve. The valve was not closed successfully and lubricating oil was released onto limestone.

Followup: No

Notes: The valve was closed. Liquid oil was recovered and pumped into a product tank. The residual oil was cleaned up using absorbent materials. The oil that was discharged on the ground outside the containment was excavated and properly disposed in permitted landfill. The operator was retrained on proper sampling techniques and refresher training for all operators will be conducted. Railcar vendors have been contacted with the intention of replacing older style valves with the more common valve types used today.
1,172.0 gallons

Underground pipeline
Cause: On October 8 at approximately 11 AM, a release of lubricating oil was reported. They were doing excavation work on an old, underground line. They are not sure if the excavator hit the line and caused the release or if the age of the line had caused wear that made the release. No more product was released to the soil, so they are sure it was probably residual material in the pipeline.

Followup: No

Notes: Due to prompt incident response to mitigate the event duration, no reportable quantities were exceeded. Some reports estimate 1 barrel of a mixture of oil and water was released into the soil. No specific remedial actions for release onto soil given.
