New Horizon Mine TR-57 <br />2"d Adequacy Review <br />21-Oct-2008 <br />Page 8 of 15 <br />Item Resolved <br />16. Some clarification and re-wording of language in the first paragraph under Evaluation <br />of Topsoil Resources, on page (d)-11 is warranted, as there seems to be a mixture of <br />outdated and current terminology used in the section. Prior to mining, our <br />understanding is that there was no dry pastureland, the land use categories were <br />irrigated pastureland, irrigated cropland (including hayland), and native <br />rangeland/wildlife habitat. Please re-word the paragraph to employ current land use <br />terminology, and ensure that the land use/soil classification relationships are <br />correctly stated. <br />Item Resolved <br />17. In the 2nd paragraph on page 2.05.4(2)(d)(12), it is stated that there are 107.96 acres <br />of Map Unit 98E mapped within the permit boundary. This is not exactly the case; <br />the 107.96 acre parcel is the total acreage of the Morgan property within the permit <br />area, which is dominated by 98E soil, and is being treated in its entirety as Prime <br />Farmland. There are additional parcels of 98E soil in other locations within the <br />permit boundary. Please amend the narrative as warranted to clarify this point. <br />Item Resolved <br />18. The final paragraph on page (d)-12 indicates that the eastern portion of the prime <br />farmland on the Morgan property has been "backfilled with subsoil". Our <br />understanding had been that this area was backfilled and graded with typical blasted <br />spoil material, which subsequently was sampled to demonstrate conformance with <br />Prime Farmland Subsoil Suitability criteria. Please clarify and amend the language <br />as warranted. <br />Item Resolved <br />19. Table 2.04.9-2, Threshold Suitability Levels for Prime Farmland Lift A and Prime <br />Farmland Lift B and Single-Lift Soils, is included on page (d)-14. Please refer to <br />Items 4 and 5 above, and revise as appropriate. In addition, we note that Boron is <br />included as a parameter in the standard regraded spoil monitoring program. Please <br />address the reason for concern with boron, and whether it has been detected at <br />elevated levels within the Bench I overburden zone. If elevated levels of boron have <br />been detected within the bench I materials that will be used for subsoil substitute, <br />boron should be included as a subsoil suitability parameter, and the table will need to <br />be properly amended. <br />Item Resolved <br />20. In the final two sentences of the second paragraph under Topsoil Salvage Depths- <br />1995 Study Area, on page (d)-16, there is reference to a 6.73 acre parcel that was <br />topsoiled to a depth of 0.8 feet, and it is stated that Map 2.05.5-4 was modified to <br />reflect the actual condition. Our review of the referenced map indicates a 6.73 acre <br />parcel within the 1995 Study Area (presumably the subject parcel), however the map <br />8
