Narrative
On may 6, 2020 at approximately 10:00 a.M., operations personnel discovered a spill of crude oil from the meter skid at bartholomew pump station. The spill was the result of a low drain 1" ball valve being opened allowing oil to free flow into a site sump which ultimately overflowed into a skid pan. Once at capacity, the skid pan then allowed the free-flowing oil to spill onto the landscape in the facility. Due to a recent rainfall event, the oil then flowed offsite through a culvert into a roadside ditch before finally being contained in a section of a drainage ditch on an adjacent landowner's property. At a later time enlink performed a root cause analysis and reviewed all pertinent data and concluded, since no one had done any maintenance or repairs on this skid, operator error was not a factor. The facility perimeter fencing shows no signs of breaking and entering, ruling out sabotage/vandalism. The team determined the root cause was more likely than not caused by a failed high-level sump switch, along with the valve going to atmosphere not being properly locked or car sealed, allowed product to overfill the sump, in turn allowing product to escape into a nearby non-flowing drainage ditch.
