Fuel was being transferred between two aboveground storage tanks at a tank farm during a rainstorm. The transfer tank was overfilled and the overfill alarm did not trigger. In addition, the secondary containment valve had been left open causing fuel and rainwater to escape the containment for several hours before the release was detected. The storage tank owner was held responsible for the costly cleanup.

A chemical producer found that the floating roof drain of an aboveground storage tank failed and released the tank’s chemical contents into a creek nearby. The company was forced to pay a large fine and cover the cost of the cleanup.

During a routine tank tightness test at a gasoline station, it was discovered that some product had leaked from an underground storage tank. It was determined that a seal in a coupling device that connected the tank to the piping had failed and gasoline was leaking out of the pipe connection.

Petroleum vapors were detected in a convenience store. After further investigation, one of the facility’s underground storage tanks was found to be leaking. The tank was taken out of service and a vapor mitigation system had to be installed in the store.
