Narrative
During a shift inspection on the morning of 12/5, the operator discovered diesel on the ground near the tank 25 manifold. Nearby funnel cups from the water draw system were full and when he went to tank 25 he discovered diesel product coming from the drain dry piping connected to the water draw piping system. They closed the 1" ball valve on the system and isolated the funnel cups from the tank but a funnel cup had overflowed causing approximately 13.2 gallons of diesel to be released to the ground and staining an area of dirt measuring approximately 6' x 4'. An investigation into what caused the overflow has been initiated but no cause has been established at this time. Update 3/23/21 for supplemental/final-the investigation determined that the tank's drain-dry air induction check valve was found to be stuck in the open position due to a small amount of sediment that preventing it from making a proper seal in the closed position, which caused diesel to route through the open check valve. These check valves will be added to the list of equipment that is periodically inspected by maintenance. Update 6/15/21 supplemental-part c-2 changed from onshore breakout tank to onshore terminal/tank farm equipment and piping as release was not determined to be considered a release from a breakout tank including attached appurtances.
