Memo - Matt Hdyes - 3 - February 23, 1990 I have been unable to find specific commitments of what thickness of topsoil will be replaced on the upper Hubbard Creek areas. I assume that approximately the same amount as was removed from all areas will be replaced on the regraded sediment pond and highwall areas. Unfortunately, the soil resource information for the upper Hubbard Creek area (page 2.04-57) gives no indication of how thick the topsoil was in this area prior to disturbance. The topsoil salvage plans for undisturbed areas (page 2.05-16) states: "The topsoil (identified by soil tests) will be segregated and removed from the area to be affected prior to excavation." and thus states no specific topsoil thickness to be salvaged. The reclamation plan for the upper Hubbard Greek area (page 2.05-36) also does not state a thickness of topsoil to be respread. Appendix E-1, reclamation costs, apparently does not have included a topsoil replacement cost as a line item. Therefore, it is impossible to determine the thickness of topsoil that was salvaged or will be replaced on the upper Hubbard Creek areas. However, one could assume that, since a greater part of the area will be left as a parking lot, some amount of topsoil will be left as excess. My inclination is to follow your suggestion to use this excess material as topdressing for the waste pile and associated regraded areas at the lower Hubbard Creek portal area. The fill required for regrading below the hillslope at the upper Hubbard Creek area could then be obtained from areas of the presently flat graded "parking lot." The following questions may be used for updating the permit document: 1.) So the permit document complies with Rule 2.05.3(5) please state what average thickness of soil was salvaged at the upper Hubbard Creek area. 2.) So the permit document complies with Rule 2.05.4(2)(d) please state what thickness of topsoil will be replaced on the regraded sediment pond and highwall areas of the upper Hubbard Creek site. 3.) The Division suggests that any topsoil left at the upper Hubbard Creek area after reclamation be transported and used on the regraded waste pile at the lower Hubbard Creek area. This would probably enhance seeded vegetation growth at the site and allow for faster plant cover and reduced erosion of the disturbed area. Please state what Somerset's plans are for the use of this valuable topsoil resource. 4.) So the permit document complies with Rule 2.05.3(5), please locate the soil storage pile directly east of the new gob disposal pile at the Elk Creek Yard on a map. 5.) Please provide a key to the Soil Types map (E8-3292).
