Narrative
On june 5, 2017 at 9:00 am local time, two terminal maintainers, while working near the 151 meter manifold at the clearbrook minnesota terminal, discovered oil under the 151 meter manifold on the concrete slab. The oil had migrated from beneath the manifold into the trough system and adjoining sump adjacent to the 151 meter skid. All the oil was contained within the building on the concrete slab and trough system. The oil leaked from the body bleed valve on the prover valve, 151-v-222, which was found to be in the incorrect full open position. It is unknown when the body bleed valve was changed from the closed to open position. The volume out was approximately 32 gallons. The oil has been cleaned up and the valve returned to the closed position. Further investigation revealed that caps were not present on the prover valve block and bleed piping at the time of the release. It has been confirmed on all three metering facilities at the clearbrook minnesota terminal that there are caps on the block and bleed piping for the prover valves. There was no contaminated soil associated with this incident.
