Rondlq <br />A private paved access road from the north end of Weld County Road #59 to the mine site is <br />currently maintained and used by CEC and others. When the Keenesburg Mine is closed, the <br />other users will continue to use this road for access to their businesses. This road was released <br />from reclamation liability and bond in 2016. <br />All CEC site roads have been classified as access roads or light-duty roads, since coal is no <br />longer transported on the site. These roads are located within the CEC permit area and are shown <br />on Map M-1. The roadway details are presented in Appendix N. <br />Longitudinal roadway profiles and a typical roadway cross-section are shown on Map N-10. The <br />topsand and overburden area access roads and light-duty roads are all routed through the <br />reclaimed areas, from the facilities area (just off the main access road) to the current area of ash <br />deposition. These roads are modified, relocated and removed as ash disposal operations advance. <br />They have been completely removed from A -Pit, and are now confined totally to B -Pit. These <br />changes are not anticipated to be pronounced, due to the relatively slow progress of the overall <br />ash disposal operation. <br />The access road located outside the excavation area on the north side of the CEC property and all <br />other access roads were initially constructed by removing about 15 inches of topsand and <br />backfilling the area with a minimum of 24 inches of clay and shale overburden materials. The <br />road surfaces were then overlain with six (6) inches or more of a sand/clay mixture (upper <br />overburden materials). Drainage ditches are also constructed along the access roadways. <br />Operation Areas <br />A recent calculation of the total remaining topsand amount for all stockpiles versus <br />anticipated needs is as follows: <br />Al, A3, B1 & B2 > 249,921 BCY <br />Topsand requirements < 167,972 BCY <br />81,949 + BCY <br />Thus, the total amount of topsand will be sufficient to reclaim areas that remain disturbed. <br />103 06/16 <br />
