I believe this will clear up the confusion about Twentymile's and Colorado Yampa Coal Company's reclamation plans. Without a good understanding of the respective operations histories confusion can be generated over the reclamation plans. You should note that the Maps 41 and 42 in permit C-81-071 provide the historic redistribution of topsoil at the site. After you review those maps you will see that none of the topsoil that was salvaged in Eckman Park was designated to be hauled to the tipple/surface facilities areas. Those maps are for information purposes as all the topsoiling activities in Eckman Park have been completed, except the limited amount of work to be done at Trudy's Corner. Trudy's Corner is the present parking place for the 8050 dragline. Perhaps a little of the history might make it easier to understand how a decrease in topsoil redistribution depths has occurred over the years. The preceding approved topsoil redistribution plan was shown on Map 41, Topsoil Removal, Storage, Redistribution, and Revegetation, in the C-81-071 permit. This plan was modified during the previous permit renewal and the topsoiling information is presented on Permit Revision Map 8, Life of Mine Topsoil Plan. A comparison of the two maps reveals the reason for the decreased topsoil redistribution depth. As you can see when comparing the two maps, Map 41 did not show topsoil redistribution over the tipple area, Haul Roads A,B & C, office area and road, shop and warehouse area, and old dragline construction site. It should be noted that these roads were constructed in the old county road right-of-way. Permit Revision Map 8 shows all of these areas being topsoiled, and as indicated in Permit Renewal Table 5, Topsoil Balance, By Areas, Life-of-Mine, approximately 0.7 feet of topsoil redistributed over these areas. These areas added approximately 141 acres to the area that will be topsoiled. Please refer to these materials for verification of the above statements. c~~us
