Corey Heaps McClave Canyon Mining, LLC February 15, 2011 Rule 4.06.5 Topsoil Reconditionin Page 24 126. MCM is proposing to apply weed free hay or straw mulch at a rate oft tons /acre. Besides mulch, will any other nutrients or soil amendments be applied to the redistributed topsoil? If any, please supply information regarding the nutrients or amendments and the rates of application. General Continents 127. MCM submitted a new list of Tables and Figures with the application. An entire new Table of Contents will need to be submitted for the text and Appendices portion of the application as well. 128. It is unclear if Section 4 of the existing permit document is intended to remain in the permit application package. Section 4 has redundant information in it now that Section 2 and 3 have been rewritten and are to be replaced with entirely new text. MCM indicates that new pages 4- 1, 4 -2, 4 -3, 4 -10, 4 -11, and 4 -73 are now to be intentionally blank. But the remainder of the information in Section 4 is either redundant or contradicts the new information presented in revised Section 2. If there is pertinent information in the old Section 4 it should be incorporated into revised Section 2 and the old Section 4 should be removed from the PAP. Please clarify this discrepancy of information presented. 129. Manz Made Fill /Landslide Feature Within the footprint of the proposed Coal Mine Waste Pile lies an oblong, elevated earthen feature ( landform). This landform appears to be approximately 650 feet in length, 200 feet in width, and rises 10 to 20 feet above the valley floor. The feature is oriented perpendicular to the valley, and appears to span nearly the full distance from the eastern bank of the incised channel of East Salt Creek to the cliffs on the east side of the valley. The top of the landform appears to be extremely level, and the slopes on the upstream and downstream sides of the feature appear to be uniformly graded. The PR -2 application makes reference to this landform in numerous locations, including the baseline soils section, the AVF determination and the Cultural Resource Inventory. A number of these references, and the interpretations made in each, are itemized below: Appendix T — Soil Resource Assessment Baseline Soil Suryey)(Jim Ny�uis) • The introduction describes "an east -west trending, flat- topped, oval shaped landform that lies across the valley and may be either an old earthen dam structure or a landslide debris Pile." • Soil Map Unit I, (which comprises the feature) is identified as "Unnamed fine sandy loam, 1 to 20% slopes ", and is described in subsection 3.2 of the report. Mr. Nyenhuis suggests that the feature is an earthen dam constructed across the valley some decades ago.
