rf ~ ~ ~~~ ~~~~~~~~~~~~~ ~~~ TOPSOIL REMOVAL FOR DRAGLINE RELOCATION Colowyo is requesting a minor revision to remove topsoil in an approximately 150-200 feet wide corridor in the 1997-2001 topsoil removal area to provide for walking a dragline from the main pit to the Section 15/16 pit. (See the attached Map 28 - Topsoil Handling for details of the particular area). The relocation of the dragline along this route is necessary to avoid a much longer walk around the pit with the associated safety hazards of overhead powerlines, trail cable, truck/shovel traffic hazards and pit delays, etc. Colowyo intends to stockpile the topsoil in linear stockpiles below the removal area. The stockpile will be located to control erosion and will be seeded to control wind and water erosion similar to all other topsoil stockpiles at Colowyo. The topsoil stockpile will be removed later in increments concurrent with typical adjacent annual pit advance topsoil stripping and utilized for reclamation. The dragline "deadhead" road will receive sufficient grading and preparation necessary to walk the dragline from pit to pit. The remaining road is not otherwise intended as a haul road and will be regraded and eventually mined through in the normal course of future pit advance. Attachment 1 provides a calculation of the bond for the additional disturbance outside of the current five-year permit term bond scenario. The total amount of additional bond is calculated to be $5,609 which when added to the current bond liability of $13,412,702 for the East Pit, Section 16 Pit and Facilities areas results in a total liability of $13,418,311. This addition results in a remaining contingency of $581,689 to the $14 million bond. The revision also includes a revised page 2.05-27 and 28 to be inserted into Volume 1 and a revised table of contents for Exhibit 20 - Permit Revision During Third Five-Year Permit Term. The revision will be inserted into the permit as item 1 of Exhibit 20.
