February 1, 1980 Mined Land Reclamation Mr. James B. McArdle Page 2 Responding to Item 3 of your request for information to supplement that .- in Exhibit C, you will find that the mining plan is clearly indicated on Exhibit C-2 as is the outline of the affected land. Exhibit D, Item 1 - The total volume of topsoil and overburden to be stripped and stockpiled is listed tabularly by mining unit in Exhibit D. The only material expected will be B Horizon material used to create the two dams. In Exhibit E we state: "A concerted effort will be made to stockpile what (topsoil) is available." You asked that we clearly indicate whether or not we plan to salvage all of the available topsoil. We feel that our verbage conveys that intent. In brief, the answer to your question is yes. Exhibit D, Item 2 - The mining plan calls for stripping topsoil and overburden estimated to be between 0 and 18 inches in the area to be affected. This is not inconsistent with the test pit information, which by reference to Exhibit C-1 you will note contains substantial test pit data outside of the proposed mining area. You will find the test pit data within the mine plan area to be consistent with the statement in Exhibit D. Exhibit D, Item 3 - The diversion and sediment pond dam dimensions will be consistent with the state engineers office recommendations and will be less than ten feet in height so they will not require a dam permit. The sediment ~ pond is to be established under the provisions of the stock pond statute and is to be left in place at the request of Terry Grazing after the completion of operations. The plan view dimensions of the dams, the pond and the diversion are all to scale on exhibit C-2. The elevation dimensions will be consistent with the topography information on Exhibit C-2. The materials for construction of the dam will be obtained from the material overlaying the aggregate beneath the topsoil. The state engineers office is currently working with us on some recommendations for minor improvements in sediment pond location and on an augmentation plan. Exhibit D, Item 4 - The table indicating disturbance categories of the affected acreage will be revised as appropriate based on our upcoming confer- ence. Exhibit E, Item 1 - In conformance with Rule 6.1 (f) no slope steeper than 2 to 1 will remain after reclamation. Slope information can be derived from the revised two-foot contour postmining or reclamation map: Exhibit F.
