• Seeding will take place when soil moisture is adequate for germination and growth or in <br />_ the fall during the dormant season. Typically, the best seeding time for this area is in the <br />mild to late fall (October and November). During this period, nights are generally cool <br />and the chances of germination are low until Spring. If seeding were to occur much <br />sooner that this date, germination would occur but establishment under these conditions <br />would be doubtfitl due to the shortness of the remaining growing season. If planting were <br />attempted much later in the year, reclamation activities could possibly be hampered by <br />early snowfall. <br />Mid to late Spring, assuming adequate moisture and sufficient snow melt, would be <br />another time in which seeding could be accomplished. However, this is a more difficult <br />season to predict in terns of proper time to seed and is often inaccessible due to tmrd. If <br />the site can be accessed, Spring would also be the optimal time for planting. <br />The reclaimed areas will be examined at least anmially to observe the success of <br />reclamation efforts. luformation derived from these observations will be provided to the <br />CMLRD as it is completed or in the annual reclamation report. <br />The Vegetation Map 6, depicts the locations of the various vegetation types in and <br />adjacent to the Permit area in addition to the reference areas for the dryland and irrigated <br />pasture vegetation types. As shown on the Vegetation Map, the vast majority of the mine <br />area falls within the dryland pasture vegetation type. <br />Reclamafion Success Criteria <br />The reclamation of disturbed areas and determination of success criteria was revised by <br />approved TR-21 and TR-33. All data related to the assessment is contained in Exhibit 5. <br />The following is a summary of the criteria. <br />At the Chimney Rock Mine, three vegetation communities will be. reclaimed including <br />dryland pasture, irrigated pasture, and rangeland/wildlife habitat. The following <br />discussion provides a description of each cmmnunity with the revegetation success <br />criteria. The Vegetation Map (Map 6 of the permit) has been revised to reflect these <br />communities and Table 10 presents a summary of the revegetation standards. <br />All data which has been used in this analysis are contained in the appendices of this <br />document. Data collected during 1990 for the proposed reference areas are presented in <br />Appendix 1. Data collected on the East Pit reclaimed area during 1988 are contained in <br />Appendix 2. Additional data collected on the East Pit reclaimed area during 1987 are <br />contained in Appendix 3. Data collected on the irigated pasture are contained in <br />Appendix 4. <br />The sampling plan for Phase IIl release was approved by MR-52 and is contained in <br />Exhibit 5. <br />r~ <br />2.05-7 Revised 5/27/04 <br />
