Overfill prevention and testing of overfill at sites is critical for staying in compliance, and for the protection of the environment. A fuel station in Marquette, Michigan was accidentally overfilled, causing a spill of gasoline into the street and into the storm drain system according to the EPA and Michigan Department of Environmental Quality. While the EPA estimated 400-700 gallons, inventory controls and the state determine around 180 gallons were spilled during the incident. Upon review of the site, it was found that the overfill alarm had an intrusion of ice into the system which was a manufacturer defect. Cleanup efforts have taken place at the site, the sewer system, and the nearby river is currently being monitored for potential contamination. As of yet, no contamination in the soil or air has been detected in the surrounding area. More information on this story can be found here.
