the fact that there will be no surface disturbance which would cause any sites to the disturbed. TCC's experience has
<br />• shown that, except for areas where there are cliffs or significant outcrops, undermining and subsiding these areas does
<br />not result in any surface disturbance, therefore, no surveys are required for these areas.
<br />NW Mains Ventilation Shaft and Thickener Underflow Project (TROT-39)
<br />TCC contracted with Metcalf Archaeological Consultants, Inc. to complete a cultural resources survey of two
<br />potential shaft sites for the new NW Mains ventilation shaft, along with the associated access roads and powerline,
<br />located in sections 16, t7, 20, and 21, TSN, R86W. The only cultural or historical site encountered was a previously
<br />recorded historic irrigation ditch (Site SRT92]). The site was determined as not eligible for the National Register and
<br />no further archaeological work was recommended. Survey results are presented in the Confidential Appendix, in
<br />Exhibit 6M, NW Mains Ventilation Shaft -Cultural Resources Survey.
<br />NMD (Panels 17 Right through 23 Right) (PR 03-06)
<br />No new surface facilities are planned for the Northern Mining District. in reference to the SW/4 of section 3, S/2 of
<br />section 4, E/2 of section 7, section 8, section 9, section 1Q N/2N/2 of section 16, and the N/2 of section 17 all in TSN,
<br />R86W the survey was not required due to the fact that there will be no surface disturbance which would cause any
<br />sites to the disturbed. TCC's experience has shown that, except for areas where there are cliffs or significant outcrops,
<br />undermining and subsiding these areas does not result in any surface disturbance, therefore, no surveys are required
<br />for these areas.
<br />18 Right Ventilation Shaft (TR 04-44)
<br />TCC contracted with Metcalf Archaeological Consultants, Inc. to complete an intensive Class III cultural resources
<br />• survey of a potential shaft site for the new 18 Right intake ventilation shaft, along with the associated access road,
<br />located in sections 2, 10, and 11, TSN, R86W. At the same time, Metcalf s project also included a Class III cultural
<br />resource survey of a second potential shaft site, four proposed seismic lines and three proposed core holes. Four
<br />isolated finds and a previously recorded site (SRT157) were found to be witlvn the azea of potential effects for the
<br />projects. The isolates were determined to be non significant resources and required no additional work. Site SRT157
<br />was recommended as "need data" by previous investigators at the time of the survey. Limited testing was conducted
<br />at this site to help determine its eligibility. No buried cultural material was recovered during the testing. Therefore,
<br />Metcalf recommended that the evaluation for SRT157 be listed as not eligible. No significant cultual material was
<br />encountered during the survey and Metcalf recommended cultural resource clearance for both of the shaft sites,
<br />seismic lines and core hole sites.
<br />Survey results are presented in the Confidential Appendix, in Exhibit 6n, Twentymile Coat Company's 2004
<br />Exploration, Class III Cultural Resource Inventory of Proposed Seismic Lines, Drill Locations and Air Shafts, Routt
<br />County, Colorado, dated November 2003.
