<br />Soil sampling will be done prior to excavation to define the limits of <br />excavation on the borrow areas and portions of CRDA 3 which will have <br />soils stripped . Sampling for SAR and EC in these areas will be done <br />on a frequency of 1 per acres, approximately 200' centers, and 2' depth <br />intervals. Sampling of topsoil piles will also be done prior to placement <br />as cover. <br />Table 14-1 lists disturbance areas and the soils balances for recfamation <br />including anticipated topsoil redistribution information. Areas where <br />topsoil has been stripped, including roads and drainage structures, will <br />generally have 6" of topsoil replaced. Table 14-2 is a listing of topsoil <br />and overburden stockpiles and the area that can be covered with 6" of <br />topsoil. Areas where no topsoil was salvaged, including the Roadside <br />South Portal area, the Unit Train Loadout area, the South Fan and the 2 <br />West Portal area. These areas will be covered with a suitable amount of <br />plant growth material and amended as necessary. <br />The original surface of many of the disturbance areas originally had a <br />rock cover density of 5 - 10%. In a review of this application by the <br />Colorado Division of Wildlife in 1996, they recommended a similar final <br />reclamation ground cover of rock. Such placement of rock can be <br />difficult and dangerous on steep hillsides and interfere with revegetation <br />efforts on slopes where drill seeding can be done. In addition, <br />placement of rock in areas where rock is not readily available can be <br />cost prohibitive. In areas where rock greater than 1 foot in diameter is <br />readily available, efforts will be made to segregate rock for placement on <br />the final surface. To minimize interterence with drill seeding, these rocks <br />will be placed in groups or piles. To minimize the difficulty and danger <br />on steep slopes, the rock placement efforts will not be made on slopes <br />steeper than 4h:iv. <br />14-15 (Rev. 12/16/96) <br />
