growth. The values of cover and production in 1981 were 73.8% and 2,787 Ibs/acre. By ]985, these two <br />parameters had increased 87.8% and 4,258 Ibs/acre. The results of this study and physical and chemical <br />characteristics of the stockpiled topsoil demonstrate that the material will be a suitable plant growth media. <br />EMD (Panel 2 Right through 6 Right)(PR 97-04) <br />The existing facilities currently in place at TCC will be used to support mining of coal in the remainder of the <br />EMD. Presently, TCC is not anticipating the need to construct any new surface facilities. Therefore, no response is <br />required for this rule. <br />NMD (Panels 12 right through 16 Right) (PR 99-OS) <br />The existing facilities currently in place at TCC will be used to support mining of coal in the remainder of the <br />NMD. Presently, TCC is not anticipating the need to construct any new surface facilities. Therefore, no response <br />is required for this rule. <br />NW Mains Ventilation Shaft and Thickener Underflow Project (TR O1-39) <br />Construction of the NW Mains ventilation shafr will result in limited surface disturbance for the shafr pad, and <br />associated access road, and powerline. An AVF and soil survey of potential disturbance areas conducted by Habitat <br />Management, ]nc. indicated that the disturbance would fall within the mapped boundaries of the Slocum loam and <br />Binco silty clay loam soil types. Three soil pits were excavated and soil parameters were documented consistent <br />with the applicable AVF requirements of Rule 2.06.8. Soil survey results are presented in Exhibit 16A, NW Mains <br />Ventilation Shafr -AVF Soil Investigation. The AVF soil survey indicates a distinct soil, vegetation, and <br />• topographic boundary between the Fish Creek AVF and the upland portion of [he study area. <br />RULE 2.04.10 -VEGETATION INFORMATION <br />(1) The permit application shall contain a vegetation map, prepared in accordance with 2.10, which <br />delineates plant communities within the permit area, or in case of underground mining, any area [o be affected by <br />surface operations or facilities, and within any proposed reference area(s). The delineation of plant communities <br />shall be on the basis of the visually dominant perennial species. <br />(2) If the applicant intends to use reference area(s) to evaluate the success of revegetation, as described <br />in 4.15.7(4), the proposed locations of these reference area(s) must be included on the vegetation map. <br />photograph, with the plant communities delineated, may be used in lieu of a vegetation map for this purpose. <br />(4) Plant communities shall be described in terms of species, composition, cover, productivity, and <br />woody plant density. The application shall include a discussion of environmental factors controlling or limiting the <br />type. <br />(5) The potential for impacts to rare and endangered plant species shall be evaluated in accordance <br />with requirements of 2.05.6(2)(a)(iii). <br />u <br />TR O1-39 2.04-50 8/10/01 <br />
