JEFFERSON CITY, MO, APRIL 20, 2010 – Contractors, working under the oversight of the Missouri Department of Natural Resources, have completed the initial cleanup of a Washington County site where nearly 600 gallons of gasoline were released on Saturday.

Department staff returned to the site Monday where a tanker truck filling an underground storage tank at the Casey’s General Store in Potosi released an estimated 582 gallons of gasoline. An inspection of the site showed no visible gasoline nor strong gas odors.

The department was called Saturday after the release sent gasoline flowing out of the parking lot and down an ally behind the store before coming to a stop at Laurel and Waters streets.  Along the way the gasoline entered the storm drain, eroded asphalt and entered three residential yards.

The Potosi Fire Department responded to the scene, constructing a dam to stop the flow of the gas into the storm sewer and using absorbent pads to soak up pools of standing gas.  The fire department then flushed the storm drain with water to push the remaining gasoline to another absorbent boon, where it was captured.

The department dispatched an environmental emergency responder to the scene to oversee the cleanup. The company’s cleanup contractor has removed the contaminated soil from the yards and ditches, and the eroded asphalt from the alley and road. The company will monitor the area during the next rain to determine if all of the gas has been removed.

The department’s Environmental Emergency Response section is called to the scene of more than 300 emergencies each year, including fires, traffic accidents, leaking storage tanks and other incidents that could have a negative environmental impact. The department’s 24-hour spill line receives more than 1,600 incident reports annually.

To report an environmental emergency, including fuel spills, please contact the spill line at 573-634-2436. For more information contact the Missouri Department of Natural Resources at 800-361-4827 or 573-751-3443, or visit the department's Web page at
