The site for the west expansion to gob pile #2 (TR -72) will initially be cleared of trees <br />and heavy brush. Then, it is estimated approximately 4,100 cubic yards of topsoil <br />and approximately 60,900 cubic yards of coverfill material will be salvaged. The <br />salvaged topsoil and coverfill material may not be stockpiled, but will likely be used to <br />for reclamation of gob pile #2. <br />The area for the west and north expansion of gob pile #2 (TR -76) will initially be cleared <br />of trees and heavy brush. Then, if topsoil is available, approximately 11,810 cubic yards <br />and approximately 29,600 cubic yards of coverfill material will be salvaged. The <br />salvaged topsoil and coverfill material may not be stockpiled, but will likely be used to for <br />reclamation of gob pile #2. A topsoil variance was approved with TR -76 and allows for a <br />variance from topsoil removal in areas that are too steep (slopes exceeding 2HAV), <br />where the topsoil is too thin (less than three inches), or where the material is too rocky. <br />This request is specifically for the planned disturbance associated with the expansion of <br />Gob Pile #2. However, if topsoil is available it will be salvaged. <br />The Operator is in the process of excavating the coverfill material from the east side of <br />gob pile #3. A portion of the coverfill material will be hauled to gob pile #2 and placed on <br />the completed slopes to the extent possible. Coverfill that cannot be placed on <br />completed slopes will be placed in one of two temporary stockpiles on the second bench <br />of gob pile #2. One stockpile is located west of the haul road, the other is located east of <br />the haul road. The material placed in stockpile west of the haul road will be placed at the <br />angle of repose and will contain up to 30,000 CY. The stockpile will be up to 50' in <br />height and approximately 400' long. (This stockpile is not an engineered fill and the <br />aforementioned dimensions are only approximate). The location of the stockpile is <br />shown on Figure 1 of the stability evaluation performed to demonstrate the weight of the <br />coverfill pile does not compromise the overall stability of the gob pile. The October 1, <br />2014 Stability Evaluation follows this section. <br />The stockpile east of the haul road will contain up to 40,000 CY and be placed at the <br />angle of repose. The east stockpile will be up to 50' in height and approximately 350' <br />long. (This stockpile is not an engineered fill and the aforementioned dimensions are <br />only approximate). The location of the stockpile is shown on Figure 1 of the stability <br />evaluation performed to demonstrate the weight of the coverfill pile does not compromise <br />the overall stability of the gob pile. The September 19, 2014 Stability Evaluation follows <br />this section. <br />MR -171 - 7 - 01/15 <br />
