    Yellowstone Mountain Club is proposing work at two locations for this permit request. The first location is at lifts tower 5 & 6 of the American Spirt ski lift and the second location is near Ranch 5. Approximately 0.22 acres of emergent wetland and 40 linear feet of an intermittent stream channel will be permanently impacted from the proposed actions. An estimated 0.19-acre of wetland and 40 linear feet (0.002-acre) of non-wetland waters of the U.S. will be permanently impacted through the proposed installation of a belowground drainage pipe system designed to reroute subsurface flows at the American Spirit project area. This action is needed in order to stabilize two ski lift towers. In addition, an estimated 0.03-acre of jurisdictional wetland will be permanently impacted during the construction of an asphalt driveway at Ranch 5.
