8. OMLR requested extensive revision to applicable text, tables, and maps, to provide <br />clarification and consistency concerning the relationship among various postmine <br />vegetation types, seedmixes, and postmine land use classifications within the NH-2 mine <br />area, in conformance with land use designations of Pule 1.04. In response, the operator <br />revised permit section 2.05.4(2)(e) and Map 2.05.4-5. <br />The amended Postmining Vegetation/Land Use Map for the NH-2 portion of the permit <br />area (Map 2.05.4-5) shows the dominant postmining land use to be Pastureland, including <br />two major reclaimed area vegetation types; Irrigated Grass (IP/Seedmix 5), and <br />Pastureland-Dry (DP/Seedmix 8). The map also depicts a minor Pastureland reclaimed area <br />vegetation type; Irrigated Swales (IPSW/Seedmix 6), and minor acreages of permanent <br />ponds, roads, and facilities, which fall under specified land use categories of Rule <br />1.04(71). A second agricultural postmining land use depicted on the map is Cropland, <br />represented by a single crop type; Irrigated Grass Hay (1CG/Seedmix 7). There is some <br />acreage of Rangeland land use (native vegetation types) within the margins of the permit <br />area, but there are no reclaimed areas designated as Rangeland. <br />The new map and text revisions are substantial improvements to the document, and the <br />clarity of the section is much improved. t eso ve,,d. <br />See new comment 22, regarding necessary demonstrations for retention ofpermanent <br />facilities and impoundments, and documentation of permit area landowner consultation <br />and comment regarding postmine land use designations. <br />9. OMLR had requested deletion of the second paragraph on page 2.05.4(2)(e)-9 which <br />appeared to be outdated (stated that "...irrigated pasture may be irrigated" and "application <br />rates will be submitted to DMG for concurrencel. The paragraph was properly deleted. <br />Itang? Awiyed. <br />See new comment 23, regarding reference to technical documents or written <br />recommendation of local agricultural authority, to demonstrate that irrigation and <br />fertilization methods and rates for irrigated hay cropland and irrigated pastureland are <br />appropriate- <br />10. OMLR had noted an error in the seedmix formulation for Seedmix #8 (Dryland Pasture <br />Seedmix), and requested that it be corrected. OMLF. had also requested that NRCS be <br />contacted regarding their experience with the recently developed "Newhy" wheatgrass <br />hybrid, which has seldom been used on reclaimed lands and with which we have limited <br />knowledge. The formulation error was corrected, but the question regarding "Newby" <br />wheatgrass hybrid was not addressed. Please provide documentation from MRCS or <br />other appropriate autborities to confirm that Newby whestgrass is desirable and <br />appropriate for inclusion in the dryland pasture seedmix at New Horizon. <br />11. OMLR had expressed concern, based on observed results at New Horizon, that the practice <br />of irrigating dryland pasture areas for the first three years as described in the application on <br />page 2.05.4(2)(e)-11 (apparently at relatively heavy rates), might be detrimental to long <br />WFC Exhibit 2 <br />Page 4 of 114
