Narrative
During routine maintenance at effingham, area personnel were not able to obtain the proper isolation by just closing the station valves. As a result, they had the mainline shut down and closed the upstream and downstream block valves. With the change in energy isolation plans, the area personnel failed to recognize and lock out the sump. Shortly after the upstream and downstream block valves were closed, the effingham sump kicked on (14:47) causing the pressure on the mainline between the two block valves to increase to 1500+ psig, exceeding 110% of mop. At 15:20, field personnel discovered that the resulting pressure increase caused the insulating gasket on the downstream side of valve bv1 to rupture, releasing approximately 7 gallons of crude oil to the environment. The line was excavated, all contaminated soil was removed, and the insulating gasket was replaced with a flexitallic gasket and new studs.
