Special Handling of Bench 1 Overburden on Morgan Prime Farmland. Per the request of the <br />Morgan Family and Dave Berry from the DRMS, WFC will special handle "all" the weathered <br />sandstone and shale strata's (Bench 1 spoil) in the 0-40 feet range of the undisturbed surface <br />back onto the Morgan property. This Bench 1 Spoil will be placed on the upper portion of the <br />finished graded backfill, just under the topsoil lay down zone. This special handling was started <br />June 2010 and will continue just through the Morgan property. <br />Thin and Thick Overburden <br />The New Horizon Mine permit area does not meet the requirements of either the thick or thin <br />overburden as shown by the following calculations: <br />103.96' maximum stripping depth <br />79.93' average overburden <br />7.94' Combined Upper and Lower Dakota <br />At the average stripping depth <br />79.93' overburden <br />+ 7.78' coal <br />87.71' material excavated <br />at 15% Swell <br />1.15 x (79.93) = 91.92 material replaced <br />91.92'/87.71' = 1.048 of the initial thickness <br />Therefore, the 0.8 requirement for thin overburden and the 1.2 requirement for thick overburden <br />are not met. <br />At the maximum stripping depth <br />96.02' overburden <br />+ 7.94' coal <br />103.96' material excavated <br />at 15 % Swell <br />1.15 x (96.02') = 110.42' material replaced <br />110.42'/103.96'= 1.062 of the initial thickness <br />Therefore, the 0.8 requirement for thin overburden and the 1.2 requirement for thick overburden <br />are not met. <br />Page 2.05.4(2)(c)-4 July 2018 (TR -84) <br />
