Qivision of MinP~ F Slurco Corporation is submitting a reques~ t~3 the Colorado Division of Minerals and Geology (DMG) for a Phase II bond release at the Canadian Strip Mine (Permit No. C- 026-81). An area is eligible for Phase II bond release when Phase I bond release has been granted, appropriate vegetation cover has been established, and erosion has been demonstratively controlled. Slurco believes it has met these conditions. The Canadian Strip Mine is a relatively small surface coal mine located approximately 12 miles east of Walden, -r Colorado. The permit area occupies a rox' ly 155 acres in portions of ~- Sectio 1 0, and 11 of Township 8 North and Range 78 West (Figure 1). The mine was operated between 1 December 1981 and 28 June 1984. Reclamation of the disturbance began in 1979 in the Phase I area and ended in 1987 in the Phase IV area. Reclamation of the disturbed mine site was completed in two phases. The first phase involved approximately 23 acres along the northern permit area boundary in Phases I to III (Figure 4). Activities consisted of backfilling, recontouring, redistributing topsoil, seeding, and mulching. These Phases were completed during 1981.

Activities included backfilling the pit, recontouring, drainage corridor construction, sedimentation pond construction, redistributing topsoil, seeding, and mulching. This phase of reclamation was completed during 1987. Slurco was eligible for Phase I bond release upon completion of the two phases of reclamation. Consequently, on 18 December 1987, Slurco filed an application with the DMG for Phase I bond release. Release of $447,870 was granted on 22 December 1988. This release reduced the remaining bond amount to $298,580. Up to 85 percent of the original bond for an area can be released under Phase II bond release. The original bond for reclaiming the Canadian Strip Mine was $746,450. Eighty five percent of this amount is $634,482. However, 447,870 was released during Phase I and $63,448 was released for partial Phase II on August 1, 1991. Consequently, Slurco is requesting a bond release in the amount of $123,164 which _ would leave $111,968. e_ ~~~ ,~ ~y~ 5'S7~`?r ~iif The following sections provide information ~i~y/Sf that Slurco believes justifies Phase II Bond release for the Phase IV area of the Canadian Strip Mine. The discussion focuses on topsoil replacement, successful establishment of vegetation on reclaimed areas, and control of erosion from the reclaimed areas. General information required for a bond release is provided in Table 1. 1
