up from borrow areas to be established at two or more locations. Given the geologic <br />conditions of the area, it is reasonable to assume that the material will contain a large <br />volume of rock, probably limiting the excavation and hauling to less efficient methods. <br />In any case, the topsoil needed to cover two of the three refuse piles is located well <br />below the application areas. Long, uphill hauls will be required to transport the material <br />to where it is needed at these sites. <br />At least two long, steep channel segments need to be constructed at the South Mine <br />area, one of these on fill material. Construction of stable channels in these conditions <br />generally requires large volumes of rock armor, or the use of liners. Use of either <br />technique is time and labor intensive, resulting in a high cost per foot of installation. <br />The demolition and removal of metallic and non-metallic structures, equipment, <br />miscellaneous materials and debris will be a huge undertaking. There are many <br />metallic buildings on site, a number of which still house office supplies, steel lockers, <br />equipment, vehicles, machinery and supplies. All of these materials will need to hauled <br />away or otherwise disposed of prior to building demolition. <br />Numerous steel facilities are in existence at the wash plant /refuse load out area, coal <br />load out, the North Mine area, and along the coal belt line. Some of these facilities may <br />have remnant value, but most will need to be cut and hauled away as scrap. <br />Large volumes of miscellaneous metallic scrap exist at the site, particularly at the South <br />Mine. These materials include abandoned and / or scrapped underground mining <br />equipment, conveyor parts, structural steel, roof bolts and miscellaneous iron. Most of <br />these materials will need to be cut, and all will need to be hauled away for disposal. <br />A large volume of concrete and asphalt is present throughout the site. Included in this <br />volume are concrete block structures, concrete buildings, building foundations and <br />underlying footers, parking lots and beltline supports. These materials will be <br />demolished and disposed of on-site. <br />The enclosed conveyor beltline which crosses the Colorado River appears to me to be a <br />formidable demolition project. The structure is anchored on both sides of the river by <br />very large concrete supports. This structure, which is suspended by cables over the <br />river, will probably be removed by large cranes working within the Colorado River. The <br />removal of the scrap materials to the banks of the river for off-site transport will probably <br />be accommodated by front loaders working in the channel. I suspect that this will be a <br />big undertaking, requiring permitting by other agencies, and involving some level of <br />environmental controls being implemented by the Contractor. <br />Some of the metallic materials at the site certainly have value. It is probable that the <br />value of these salvageable materials would, to a certain extent, offset the expense of <br />removing the non-salvageable metallic materials. It is my understanding, however, that <br />the salvageable materials have been identified by the owner or operator of the mine, <br />and that these materials are scheduled to be auctioned off in the near future. It would <br />be unfortunate if only the valuable materials were removed from the site, leaving the <br />
