Coal extraction ceased in 1987, with all stockpiled coal removed <br />. by 1991. Concurrent with coal extraction, backfilling, final grading, re-topsanding and <br />seeding occurred as pits were completed. The lazgest azeas of pit reclamation occurred <br />between 1985 and 1987. With the cessation of coal extraction in 1987, the remaining <br />open pits (A and B) were converted into approved ash disposal facilities, for controlled <br />placement and disposal of ash from the power generation facilities located on Coors <br />property in Golden, Colorado. Placement of fly ash and subsequent backfilling, grading, <br />topsanding, and revegetation in A pit was completed in 1999. Ash placement and <br />contemporaneous reclamation continues in B pit. Final backfilling of the B pit will not <br />occur prior to final ash placement. Additional reclamation work has occurred at the mine <br />in addition to reclamation of the open pits. Removal of facilities and equipment <br />commenced in 1994, with the removal of the coal storage facility and dragline. After <br />removal of the coal storage facility, additional backfilling, grading, topsanding, and <br />seeding occurred in the fall of 1995. In addition to reclamation of the pits, ancillary roads <br />and support areas have been backfdled, regraded, topsanded and revegetated. Currently, <br />the only active or unreclaimed azeas at the mine include B pit, the long-term spofl area, <br />topsand piles, access road segments, and the office and maintenance facilities. Small azeas <br />of reseeding have occurred since 1987, upon the recommendation of CDMG and CEC. <br />Reseeding occurred in azeas where disturbance occurred subsequent to the initial seeding, <br />or the initial seeding did not take. Areas of initial seeding and reseeding aze designated on <br />the revegetation sampling map (Map L-5). <br />2 <br />
