The location~6f the crushing plant can ~ found on Figure 2 of <br />the April 14, 1981 application and the list of machinery. (primary <br />crushing by a Long-Airdox Feeder-Breaker Model No. FBM-40, and <br />secondary crushing by a two-stage Gundlach Model No. DA-56 crusher) <br />can be found in Section 2.05.3(3)(b), Operation Plan - Permit Area, <br />Mine Facilities, Existing Structures. <br />SIGNS AND MARKERS <br />4.02.2,3,5,7 <br />Wyoming Fuel Company has been and will continue to post <br />appropriate signs and markers as required and will continue <br />to meet the established performance standards. <br />HAUL ROADS <br />4.03(3)(a) <br />Temporary in-pit haul roads will have overall grades of about <br />10 percent with short pitches up to 15 percent. All drainage from <br />such roads and roadside ditches will be contained within the mine <br />area and only discharged through approved sediment control structures. <br />4.03.1(5)(b) <br />Wyoming Fuel Company is aware of the fact that most of the <br />overburden exhibits high sodium absorption rates (SAR). Separating <br />strata to locate road surfacing exhibiting the lowest SAR would be <br />difficult. However, the high SAR values are naturally occuring in <br />this area and in fact the highest values are found immediately <br />beneath the topsoil which is material that is unsuitable for road <br />surfacing. This most frequently used strata for road building is <br />the massive light grey sandstone above the coal, used because of its <br />physical volume (ample quantity), durability and good working qualities. <br />This sandstone generally exhibits lower than average SAR values. <br />Wyoming Fuel Company suggests that any surfacing material used, <br />the light grey sandstone in particular, should not be considered acid <br />or toxic forming due to the fact the high SAR values are naturally <br />occuring and the road surfacing will not have any detrimental effect <br />on pre-existing conditions. Wyoming Fuel Company will attempt to <br />minimize use of. strata exhibiting the highest SAR's. <br />4.03.1 (f) <br />The haul roads will be reclaimed consistent with the final <br />contours submitted with the reclamation plan in this Addendum <br />(see Fiqure 2A). <br />-8- <br />
