On September 20, 2010, Rosebud Mining Company, while exploring the site to determine its suitability for mining, cleared shrubs, tree litter, small trees and soil to level a path for a drill, using a D-7 bulldozer. The clearing resulted in the placement of fill material in approximately 20 linear feet of Stream #1 and 30 linear feet of Stream #2. The Rosebud Mining Company also placed a culvert in Stream #1 using a rubber-tired backhoe. Under the AOC, Rosebud Mining Company will restore the two streams by removing any fill placed in them, and will submit a Restoration Plan. Upon EPA?s approval of the Restoration Plan, Rosebud Mining Company will implement the Restoration Plan within four months of EPA?s approval of the plan.
