On Sunday afternoon, May 29th, EPA was notified that a tank had been overturned while attempting to move it from one property to another. The tank had an estimated capacity of 300 gallons and was believed to contain 100 - 200 gallons of diesel. The diesel fuel released to the soil and then to Ten Mile Creek, a tributary to the Boise River. Attempts to have the responsible party hire a qualified contractor failed and the State of Idaho requested EPA's assistance in conducting the cleanup. EPA's cleanup contractor arrived on scene on Monday, May 30th and began cleanup.
