Mr. ~amer R Stark ' <br />Cahrado Divirion ofMineroG eS'Geology <br />AuBrrtt 7, 2002 <br />Poge 5 <br />reclaimed Mine Portal Area; and the Coal Loadout Reference Area (Grassland Type) to the reclaimed <br />Loadout Area). <br />Review, however, of the Mine Area Vegetation Map, (Map 16), and consideration of the previous response to <br />Comment 17 indicate that much of the Mine Portal and assodated mine facilities azeas were included in the <br />Grassland vegetation type and/or "Lands Disturbed by Previous Mining". It would be appropriate to <br />evaluate these azeas against the Refuse Site Reference Area (Plot A -Grassland Type). Other site disturbance <br />is very limited and would normally be evaluated against the Mine Portal Reference Area (Plot B -Ponderosa <br />Pine-Pinyon Juniper Woodland Type). The CDMG has suggested, and EFCI concurs that a single weighted- <br />average reference area comparison for the reclaimed Mine Area would simplify and facilitate revegetadon <br />success evaluations. Accordingly, EFCI has developed aweighted-average revegetadon success standazd, <br />reflecting pre-milting vegetation types and conditions. Based on the affected acreage of the two primary <br />premine vegetation types within the mine disturbance azeas, the weighted average revegetadon success <br />standazd will reflect 79.8 potent grassland (Plot A - Grassland Type) and 20.2 percent <br />ponderosa/pinion/juniper (Plot B -Ponderosa Pine-Pinyon Juniper Woodland Type). Those portions of the <br />reclaimed Loadout Area designated for a postmining land use of rangeland/wildlife habitat would be <br />compazed to the Coal Loadout Reference Area (Grassland Type). Relevant permit text sections have been <br />revised to accurately re Elect the basis for revegeta[on success evaluations for all disturbed azeas at both the <br />mine and loadout and copies of the revised pages are included with this TR submittal. <br />Comment 19 -EFCI har committed to exrenrive live rhrub and tree planting at the mine rite and the loadout. Pkare include <br />a narrative in the revegetadon sections of the permit that includes the method and timetable far there tranrplantr as well ar a <br />method for ensuring their long-term totters. <br />Response: Section 2.05.4 (pages 2.05.¢23R and 24) currently provides a discussion of tree/shrub transplant <br />plans, protective measures, and provisions for addressing seedling loss. Section 4.15 (page 4.15-3) references <br />back to this discussion. <br />It is anticipated that conventional transplant methods will be used, including selection of appropriate adapted <br />transplant stock and selective placement of healthy labeling transplants with time-release fertilizer tablets to <br />maximize the potential for transplant survival. Based on site conditions, including soil and prevailing <br />atmospheric moisture conditions at the time, small diameter perforated pipe drains may be placed adjacent to <br />the transplants, if appropriate, to collect and provide supplemental moisture during initial establishment. <br />Protective netting may also be placed azound the transplants if there is significant potential for wildlife or <br />rodent damage. EFCI will group transplants as "tree/shrub islands" both to improve the potential for <br />seedling survival and to optimize the relationships between shrub and meadow azeas for grazing and wildlife <br />use (i.e.: edge effect, cover zones, etc.). Transplant sites will be cazefully selected to optimize the potential for <br />survival and subsequent natural re-seeding with consideration to aspect, micro-habitat, moisture, and location <br />on slopes. Grass seeding rates will be reduced in transplant azeas to minimi>e competition. Both initial <br />xevegetation success monitoring in Year-3 and informal site inspections will provide a good indication of <br />transplant survival and any requirements for supplemental transplants or other measures. Information on <br />transplant methods has been incorporated into the permit text and proposed transplant locations have been <br />added to the reclamation map. Copies of the revised permit text and reclamation map aze included with this <br />TR submittal. <br />RULE 5.02.4 <br />Comment 20 - Becaure the mine it curnently being reclaimed and the facilltier are being demolished and the entire area zr bezng <br />backfilled and regraded, the Operator needy to relocate alt required recordr to a location that it accerrible to the public (ruch ar the <br />county courthoure). <br />
