sealed, backfilled, or otherwise properly managed (4.07.3). VI. Backfilling and Grading{tc \l3 "VI. Backfilling and Grading} A. In order to conserve soil moisture, ensure stability, and control erosion on fmal graded slopes. The Division approved cut-and-fill terraces. These terraces are compatible with the post-mining land use, and will meet all the requirements of this Rule (4.14.2(2)). B. As noted eazlier, Kaiser Steel Resources has completed all backfilling and grading at the mine site in a manner consistent with the approved plan. A complete 60 percent Phase I bond release was approved in 1992. VII. Revegetation{tc \13 "VII. Revegetation} A. Information on baseline vegetation for the approved permit can be found in Section 2.04 of Volume I and Exhibit 5 of the permit application. Three vegetation communities were disturbed by mining operations. They were the Pinyon-Juniper, Mountain Shrub and pasture land. Information on the revegetation plan and revegetation success criteria, as well as methods to measure herbaceous cover and production, species diversity, and woodyplant density can be found in Section 2.05.4. The Division approved the use of introduced species in the reclamation seed mix for the irrigated pasture area. The applicant submitted information which showed that the introduced species were desirable and necessary to achieve the approved post-mining land use, and aze not poisonous or noxious. The Division approved the use of reference azeas for dryland and irrigated pasture land communities for purposes of determinations of revegetation success. Comparisons between reclaimed and undisturbed areas, in order to demonstrate that success criterion of4.15.8, 4.15.9 or 4.15.10 has been met, will be based on the following: For azeas reclaimed as dryland pasture, vegetative cover and herbaceous productivity will be equal to or greater than 90% of the cover or productivity in the dry land pasture reference area. There will be at least 2 cool season perennial grasses, 1 warm season perennial grass and 1 perennial forb, each contributing between 3 and 60°!o relative cover. There is no success standazd for woody plants. The same success criteria apply to areas reclaimed as range land/wildlife habitat. For areas reclaimed to irrigated pasture, vegetative cover and herbaceous productivity will be equal to or greater than 90% cover or productivity in the irrigated pasture reference azea. There will be at least 3 cool season perennial grasses, each contributing between 3 and 40% relative cover. There is no success standard for woody plants. VIII. Post-mining Land Use{tc V3 "VIII. Post-mining Land Use} A. The Division has approved the original post-mining land use of rangeland and wildlife habitat. The land-use meets the criteria of Rule 4.16.3. 15
