West Elk Mine <br />Field Investigations <br />Archaeological reconnaissance of the West Elk Mine study area (Figure 3) have been conducted to <br />assess the extent and nature of any cultural resources contained within areas of potential impact <br />from development related to West Elk Mine. Field studies, and associated laboratory operations <br />and report preparation were completed by professional archaeological teams as documented <br />in Exhibits 10, 10A, 1013, IOC, IOD, and 10E. An archaeological reconnaissance was conducted <br />for the Refuse Pile Expansion (RPE) area in September 1995, as documented in the RPE exhibit <br />(Exhibit 70). <br />Areas previously investigated included the main mule surface facilities area, areas innmediately <br />adjacent to the surface facilities area, the Sylvester Gulch Test Adit and access route, the Sylvester <br />Gulch Facilities Area, Sylvester Gulch Road, potential waste rock disposal sites, the Lone Pine <br />ventilation facilities area, the RPE area, Methane Drainage Well pads, and the access routes to all <br />surface facilities, methane drainage wells, and exploration sites. More recent cultural resource <br />investigations include eight field studies within and in proximity to the South-of-Divide permit <br />revision area that included portions of the permit area and were conducted for exploration and <br />assessment of the coal deposits (Spath 1995a, 1995b, 1996, 1997, 1998, 1999a, and 1999b and <br />Susan Chandler, Alpine Archaeological Associates, 2007). These inventories covered a total of <br />approximately 250 acres of small blocks and linear corridors for exploratory drill holes, access <br />corridors, and seismic corridors. The inventories were completed prior to potential ground <br />disturbance by these exploration activities or drilling activities. A professional archaeologist <br />completed field studies and report preparation. Maps 7, 7A, and 7B illustrate the areas surveyed. <br />Exhibit lOD includes an illustration of the Sylvester Gulch facilities areas surveyed. A summary <br />listing of the cultural resource investigations completed within the West Elk Mine permit area and <br />previously documented cultural resources is provided in Exhibit 10E. <br />Literature Search <br />The National Register of Historic Places and the Colorado State Register of Historic <br />Properties were checked for listed sites in the vicinity of the permit area. No listed sites <br />were found. The archaeological sites and surveys files of the OAHP were reviewed for <br />previous surveys and previously documented sites within or near the permit area. As <br />previously noted, the files search listed 17 cultural resource investigations that included <br />portions of the legal sections containing the permit area. The identified investigations are <br />listed in Exhibit 10A. Several of the more recent investigations were for activities <br />associated with the current mine permit area. The files search also listed one previously <br />documented prehistoric site and two prehistoric isolated finds in the permit area. The <br />cultural resources are not recommended as potentially eligible for listing on the National <br />Register of Historic Places or the Colorado State Register of Historic Properties. <br />Therefore, there are no known sites that are listed on or eligible for the National Register <br />of Historic Places in the permit area. <br />Archaeological Clearance <br />Reports of archaeological surveys for the permit area have been forwarded to the USFS, <br />2.04-8 Revised June 2005 PRIO; Rev. Mach 2006 ; Rev. April 2006 PRIO, Sep. 2007 PR12
