Construction of the coal mine waste pile will be a phased project with placement of gob <br />starting on the western edge of the pile, and progressing eastward. At the time of this <br />writing, the majority of the gob footprint has been cleared of all organic material and <br />topsoil. <br />Until the underdrain as submitted under Technical Revision No. 80 is approved, no gob <br />will be placed within 50' of the underdrain location. Page 4b shows the underdrain <br />buffer zone location. The buffer zone will remain in place until the underdrain <br />installation is complete and has been certified. <br />Minor Revision 134 approved the placement of gob in the westernmost section of the <br />pit; this section will become part of the proposed gob drying area, as shown on page 4b. <br />The purpose of the gob drying area is to provide an area for temporary storage of gob <br />for drying purposes. End - dumped gob in the gob drying area will be worked with dozers <br />and track hoes to assist in the drying process, and when necessary mixed with coverfill <br />material to expedite drying efforts. Trenches will be cut through the end - dumped <br />material to allow better drainage. Then, gob will be transported to the east section of <br />the gob pile, placed and compacted. <br />The existing gob in the proposed gob drying area (as shown on page 4b) will be graded <br />and sloped at a minimum of 2% toward ditch J3. The existing gob will be compacted in <br />accordance with the requirements of Rule 4.10.1(3) prior to using this area as the gob <br />drying area. The maximum amount of un- compacted gob in both refuse areas (Gob Pile <br />#2 and Gob Pile #3) will not exceed 200,000 cy total. <br />Coverfill salvaging efforts will continue in the eastern portion of the gob pile. Salvaged <br />coverfill will either be placed in stockpile, for use at gob pile #2, or used for <br />contemporaneous reclamation efforts at gob pile #3. There is an area where topsoil still <br />needs to be salvaged and when complete will be placed in the existing stockpile. <br />MR -141 - 4a - 10/07/13 <br />
