J ~ <br />the site was apparently not irrigated. The application should be <br />amended to address irrigation of the designated irrigated hayland <br />below the terraces and the Vulcan Ditch System. <br />Additionally, patches of several noxious weed species including <br />Russian knapweed, field bindweed, Canada thistle, and whitetop were <br />observed on the reclaimed area, most noticeably on the irrigated <br />cropland portion of the reclamation. Such species are obviously <br />incompatible with the postmine land use, and the application should <br />be amended to include a noxious weed control plan. <br />2. Rule 4.15.5(1) states that "livestock grazing must not <br />commence until one year after seeding or planting and shall be <br />managed to promote the postmining land use." <br />On page 4-60, the permit application states that "grazing will not <br />be allowed until one year after seeding, and will be managed to <br />promote the postmining land use..." On page 4-60, the application <br />describes a perimeter fence, "which will be kept in place for 3 <br />years, or until grazing pressure can be tolerated." At the time of <br />my inspection, between 36 and 50 cow/calf pairs had apparently been <br />grazing on the fenced reclaimed area for at least 5 weeks. The <br />area showing the heaviest grazing use was the relatively flat <br />"irrigated hayland" portion of the reclaimed area, with even the <br />noxious weed species grazed. It seems questionable whether such <br />heavy growing season grazing during the second year after seeding <br />is "promoting the postmining land use", particularly with respect <br />to the irrigated hayland acreage. <br />The application narrative should be expanded to discuss how grazing <br />will be managed to promote the postmining land use, and how the <br />vegetation will be assessed in determining when grazing pressure <br />can be tolerated. <br />3. Rule 4.15.9 requires that, "for areas to be used as cropland, <br />success of revegetation shall be determined on the basis of crop <br />production from the mined area as compared to approved reference <br />areas or other approved standard(s)." <br />On this subject, all I could find in the application was a <br />statement indicating that, for the cropland area, "productivity <br />will be compared to adjacent cropped areas." Considerable <br />elaboration is necessary with respect to identification of the <br />reference field, description of the comparison methodology (e.g. <br />use of a specified sampling technique or a total harvest method), <br />and discussion of statistical testing if comparison will be based <br />on sampling. The operator should refer to the Division's April, <br />1995, GUIDELINE REGARDING SELECTED COAL MINE BOND RELEASE ISSUES, <br />and the 1988, GUIDELINES FOR COMPLIANCE WITH LAND USE AND <br />VEGETATION REQUIREMENTS FOR COAL MINING. <br />4. For the non-cropland portion of the reclaimed area, woody <br />plant density and species diversity standards are clearly set forth <br />in stipulations to the findings document, and both the findings <br />
