As presented in Rule 1.04(111), the definition of "road" does not include roadways within the <br /> immediate mining pit area. This includes the haul roads in pits. <br /> Topsoil Removal <br /> Topsoil is removed using dozers, excavators or front-end loaders, and haul trucks or scrapers. <br /> Generally, a dozer is used to push the topsoil off of the slope and into a drainage bottom or other <br /> flatter area. The topsoil is then loaded into haul trucks using an excavator. Stripped topsoil is <br /> hauled directly to graded spoil areas on the trailing edge of the pits or to topsoil storage piles for <br /> later distribution during reclamation. Topsoil from the East Pit and West Pit mining areas have <br /> been stored in several topsoil stockpiles as shown on Map 28 of the PAP. Topsoil from the South <br /> Taylor mining area is also being stored in topsoil stockpiles as shown on Map 28, 28A and 28C of <br /> the PAP with Collom Topsoil shown on Map 28C of the PAP. <br /> Blasting <br /> Blasting operations are utilized to fracture overburden and interburden in the pits. The rubble <br /> overburden from the top in the edges of the West Pit was removed by truck and shovel operations. <br /> This material was hauled around the active pit and dumped into the active pits on the trailing side. <br /> Cast blasting with explosives and back casting with draglines are utilized for the removal of rubble <br /> overburden above the lower seams, and was used in the East Pit and Section 16 Pit. Initial box- <br /> cut material from the East Pit was placed in the Streeter Fill. Initial box cut material from the West <br /> Pit was placed in the West Pit permanent excess spoil fill. Initial box cut material from the Section <br /> 16 Pit was placed in the Section 16 Fill. <br /> After blasting, the truck and shovel operations also removes the top three or four seams of <br /> overburden and interburden at the South Taylor Pit. This material is hauled to temporary <br /> overburden storage piles TS West and TS East (to the north of the pit). Approximately 42.7 <br /> million cubic yards of material will be placed in the temporary overburden stockpiles. Upon the <br /> completion of mining, this overburden will be hauled back to the South Taylor Pit. The initial box- <br /> cut material for the South Taylor Pit will be placed in two permanent valley fills (the West Taylor <br /> and East Taylor Fills). Approximately 90 million cubic yards of material will be placed in the two <br /> fills. <br /> For development of the initial box cut of the Collom Pit, similar procedures as the South Taylor Pit <br /> will be used. Once the overburden is sufficiently fragmented from blasting to allow for efficient <br /> removal and loading, Colowyo will utilize truck and shovel techniques to load and haul <br /> overburden. Overburden will be transported to the temporary out-of-pit spoil stockpile located to <br /> north of the Collom Pit. A total of approximately 28 million cubic yards of overburden will be <br /> placed in the Collom temporary spoil pile. Of that 28 million cubic yards, approximately 21.4 <br /> million cubic yards will remain out of pit and 6.6 million cubic yards will be used for final backfill <br /> in the Collom Pit. <br /> Coal Production <br /> Extraction of coal is projected to continue until the year 2026.
