These two portals will be opened, drained, closed with non- wildlife accessible closures and capped with excavated material with drainage features installed to conduct mine water to the adjacent natural drain. Excess material will be transported to the onsite waste area. A Class III ditch and culvert will be installed in the natural drain to protect the drainage features and conduct the collected drainage ultimately to the natural stream. At the middle area, a slide threatening a structure, open and draining portals and a water body impounded above open portals are causing stability and safety concerns. The slide will be addressed by excavating to rock and installing subdrain between the structure and the slide area. The subdrain will outlet into a concrete block- tied mat ditch along the driveway to the natural stream. The water body impounded over existing portals will be drained, the two portals closed with non- wildlife accessible closures and drainage features installed to conduct future drainage to the natural stream. Waste material generated by this project will be used as a top treatment above the portal closures. Waste placement along with grading will make the area nonimpounding. An area north of the Williams Fork stream wil

Project limits for the offsite waste area includes 9. 35 acres, with an expected disturbance of 0. 2 acres. No trees over 3 DBH will be removed as part of this project. No streams or waterways will be impacted. Rock, debris, and coal refuse washed out uphill from a residence, blocking a driveway to one home and filling the yard up to another house with the debris and slide material, causing extensive damage to the property. Drainage from above where an old pond is located washed out during a heavy rain, releasing the material. A short term cleanup project will take place to restore driveway access for both homes, clean up the slide material in the yard, and install temporary protections in anticipation of a larger project to reclaim the area up the hill. Slide material will be hauled to a previously used AML waste, a site 2. 9 miles from the project site on a reclaimed and fully released permit area. The waste material we be buried under topsoil excavated at the waste site to promote proper revegetation. The ditch above the driveway will be cleaned out and re- established with a temporary sump and silt trap as well as a debris barrier to prevent further damage. The follow up project will occur separately and will replace any temporary structures w
