AUG 1 :> 1981 EXHIBIT E - RECLAMATION PLAN MINED LAND RECLAMATION Colo. Dept. o? Natural Resources This Exhibit E, dated August 7, 1981, is an update and an expansion of the plan submitted and approved in 1978. It is not intended to replace Exhibit E or the approved plan, but rather is to supplement it. Included, are those areas added via technical revision. Where appropriate, areas are broken down into sub areas and/or a summary status included. Area #1 Dump site located in the NE-1/4 of the NW-1/4 and the SE-1/4 of the NW-1/4 of Section 25. An area of 30.00 acres. This dump has been permitted by the Garfield County Commissioners after review by the Mined Land Reclama- tion Division (HERO). The stability of the 8.8 million cu. yd, site is dis- cussed in "Environmental Considerations For a Proposed Mineral lJaste Disposal Pile in Logan Wash" a copy of which is attached and incorporated herein. The slopes of this dump will be at the angle of repose, which is 36-38 degrees (approx. 1.04:1). The surrounding natural talus slopes lie at the same angle. The stability of this dump is discussed in the attached report just men- tioned. Slumping and sloughing are terms generally used for beds of soft mud, sand, and ooze that may slide when they are completely saturated. Raw shale does riot fit this description and due to its angular texture will be stable at slopes of 1.5:1 or flatter (horizontal: vertical). Slumping and sloughing are not a concern with shale having particle size precluding saturation and movement; in any event, they are not a concern in a semi-arid setting such as that at Loyan Wash, The dump will be similar in appearance and stability to the talus slopes of the same material which are common in the area. keclamation will not beyin until after the dump is filled to capacity since the slopes and benches will be actively building and advancing during
