Corey Heaps <br />McClane Canyon Mining, LLC <br />February 15, 2011 Page 7 <br />C. Include contour cross section of proposed final reclamation in the canyon area. <br />d. Include the revegetation plan for the newly proposed disturbance in the canyon area. <br />29. The following questions pertain to Appendix U of PR -2. <br />a. Vegetation Sampling, Second paragraph, page 2 — Map 2.04.10 -1 is not in packet. If <br />the text is actually referring to Figure 4.5 -3 (Vegetation - Area South of Portal Haul <br />Road), please revise all references to this map throughout the document. Additionally, <br />reference is made to map 2.045.10 -1 on page 6. Please correct references and be sure <br />all maps are included. <br />b. Production, page 4 — The text states "As required by Rule 4.15.11 shrubs, subshrubs and <br />noxious weeds were not clipped since they cannot count toward the proposed <br />revegetation production..." Noxious weeds are not excluded in 4.15.11(b)(i) to not be <br />clipped/counted. Please reference the appropriate rule allowing the exclusion of <br />noxious weed in counting/clipping. <br />C. Shrub Density, First paragraph, page 4 — Tannsects in the reference areas are very close <br />together in Figure 4.5 -3 making it difficult to determine if there is too much overlap of <br />data. Please highlight the 23 transects in Figure 4.5 -3 that were used to determine Plant <br />Cover ( %) and Shrub Density (# per 100 m2) indicated in Table 2.04.10 -2. <br />d. Shrub density, Second paragraph, page 4 — Is Saltcedar and Tamarisk the same species <br />referred to in this statement about stem counts? Please use consistent terminology. <br />e. Statistical Analysis of Data, page 5, first paragraph — There is a mistaken reference. <br />The narrative says "As required in Section 4.15.10, a minimum of 15 cover transects <br />and 30 production transects are typically collected from each vegetation area sampled." <br />Section 4.15. 10 is Revegetation Success Criteria: Previously Mined Lands; Areas to be <br />Developed for Industrial or Residential Use. Please correct the reference in this section. <br />f. Statistical Analysis of Data, page 5, second paragraph — MCM states "a minimum of at <br />least 30 shrub density transects be sampled for each plant community." Please refer to <br />the rule that CAM is referencing. <br />g. Results, page 6, Vegetation sampling, second paragraph. — The definition used for major <br />vegetation types is incorrect. The definition for minor vegetation type is used. Please <br />reword using the definition for major vegetation types in the Division's 1988 <br />Vegetation Guideline on page 3. <br />h. Results, Page 7, Field Sampling Dates - Table 2.04.10 -1, CAM - Colorado LLC - <br />McClane Canyon Mine — Refuse Pile Expansion — Plant Species List referenced on <br />page 18 is not labeled correctly according to the text in paragraph 1 on page 7. <br />
