Narrative
On 7/16/2015 maysville station was down for scheduled maintenance work. As part of the lo/to to isolate maysville station a mlv outside of the station was lo/to'd. A manual pump at an injection point between maysville and the lo/to'd mlv was turned on. Normal flow from this injection point is east to seminole. However, the manual injection pumped against the closed mlv which caused pressure to backup to maysville station. This backup caused the sump drain lines of the mainline pumps to overflow releasing <1 barrel to the concrete pad where the pumps are situated. The manually operated field pump was shut down relieving the pressure and the release stopped. All free oil was immediately cleaned up from the conrete pad.
