On April 5, 2012, Region 10 entered an Expedited Settlement Agreement in connection with the City Service Valcon Tank Truck Spill case. This enforcement action resulted from a 950-gallon unleaded fuel spill that occurred in November 2011. The spill was caused when a tank truck owned by City Service Valcon had an accident on Highway 12 and the trailer of the truck broke away, colliding with a vertical rock face. A slow discharge of gasoline was released into a roadside ditch directly adjacent to the Lochsa River. The terms of the settlement require City Service Valcon to pay a penalty of $3,000.
