Cultural and Historic Resources -Rule 2.04.4 and 2.05.6(4) <br />Cultural and historic resources aze discussed in Section 2.04.4 of the permit document. Records <br />from the Historic Buildings and Sites file of the Colorado Historical Society and the <br />Archaeological Survey file of the Office of the State Archaeologist were reviewed for previously <br />recorded sites. No evidence was found indicating the existence of known sites in the vicinity of <br />the mine. An archaeological reconnaissance was also conducted. Field studies, laboratory <br />operations, and report preparation were completed by an azchaeological team from Fort Lewis <br />College in Durango, Colorado. This report can be found in Exhibit 10 of the permit document. <br />No sites were found as a result of the field study. <br />Additional surveys for Jumbo Mountain were completed by Western Cultural Resource <br />Management, Ina (WORM, Inc.) during October and November 1993. Map 7A shows the areas <br />surveyed during the field reconnaissance. A literature seazch was conducted by WCRM, Inc. in <br />September 1993. That seazch identified 15 cultural resource reports. Those reports aze listed in <br />Exhibit 10A. Exhibit l OB contains the results of the survey. Exhibit 11 contains cleazance <br />documentation from the State Historic Preservation Officer. <br />A Class II Cultural Resource Assessment was conducted by Metcalf Archeological Consultants, <br />Inc., with the results of the assessment contained in a report dated January 1995. This report was <br />submitted with Permit Revision No. 6 and is contained in Exhibit l OC. The State Historic <br />Preservation Officer was contacted by the Division on August 21, 1995, and indicated <br />concurrence with the submittal. <br />The State Historical Preservation Office indicated in a letter to the Division dated February 21, <br />2006 that Permit Renewal s will have no effect on historical properties because the renewal <br />proposes no disturbance outside the area which has been previously cleazed by that office . <br />Geology -Rules 2.04.5 and 2.04.6 <br />The applicant describes the geology of the permit and adjacent azea in Section 2.04.5 of the <br />permit document. Additional information is detailed on Map 9, which details the geology of the <br />lease azea, as well as the coal outcrop line and the strike and dip for the F and B Seams. <br />Stratigraphic information is shown on Maps 10 through 23. <br />The permit azea lies on the southeast mazgin of the Piceance Basin and just south of Grand Mesa. <br />The general geology of this azea consists of gently (three to five degrees) north-northeast dipping <br />beds of sandstone, shale, and coal of upper Cretaceous and eazly Tertiary age. <br />The geologic formations exposed in the North Fork Drainage Basin consist of Late Cretaceous to <br />Eazly Tertiary Age sedimentary strata, Tertiary Age igneous intrusives, and Quaternary Age <br />alluvial and colluvial deposits. The units aze described below in ascending order. <br />The Mancos Shale is the oldest stratum exposed in the region, and is of Late Cretaceous Age. <br />This unit is composed of over 4,000 feet of gray marine shales and minor interbedded buff <br />sandstones. This unit is highly erodible and unstable. Erosion and oversteepening of slopes in <br />26 <br />
