Narrative
Mainline booster pump continued running after mainline pump was shut down. This was due to a communications error in the plc caused by a momentary loss of power. When the booster pump continued to run after the mainline unit was shut down, a thermal relief valve on the filter vessel relieved at a setpoint of 150 psi. All happened during a heavy rain event with the relief into the sump system overwhelmed the drain. A valve in the drain system to the filer dry box provided a path for the diesel to spill onto the cement. To correct the issue, the controls group fixed the glitch in the plc and the setpoint of the relief valve was raised to 270 psi.
