• end species diversity success criteria will be based on performance standards. As
discussed later in this section, seasonal variety es a success parameter is not epplfcable
because of the cool season vegetation dominance in the native areas.
The extended reference area approach maximizes the use of extensive undisturbed lands
within the permit area that contain the same vegetation types found in the disturbance
area. This allows for a more valid comparison of native vegetation to reclaimed lands.
Mining of recoverable coal seams during the first permit term is more or less centered in
the northern portion of the permit area (excluding the haul road corridor). Additional
mine-related disturbances for facilities, haul roads, sediment ponds, topsoil stockpiles,
end all grading disturbance are located adjacent to this portion of the permit area and in
the haul road corridor. The total maximum disturbance area during the first permit term
and the projected life-of-mine disturbance are illustrated on Exhibit 22-1. These lines
provide en estimate of undisturbed vegetation available for inclusion in en extended
reference area. The extended reference area includes all undisturbed lands between the
permit boundary and the life-of-mine disturbance boundary end the first permit term area.
As can be seen from review of this exhibit, considerable undisturbed areas will remain
• after mining-related disturbances. These undisturbed areas represent simiLer ranges of
soils, elevations, aspects, slopes, and phases of the representative vegetation
communities in the effected areas. All major premine vegetation communities ere
represented in these undisturbed areas (overlay Exhibit LO-t wiCh Exhibit 22-t). The
extent of these undisturbed vegetation communities and the close proximity to the
reclaimed areas provide the best comparison to premine site end vegetation conditions
possible, senate Coal Company has surface control of ell lends to be included in the
extended reference area. This will allow SCC to manage the reference areas in accordance
with the approved postmining land use. It will also facilitate similar management for
both the reference and revegeteted areas for any bond release evaluations during the lest
two years of the liability period. Reference area comparability is in Appendix 22-I.
The following details the comparisons to be made between reference area information and
the various revegetation communities to be returned on the postmining landscape. These
comparisons reflect reclamation experience end revegetation monitoring date from the
nearby Seneca II and Seneca II-w Mines. The comparisons attempt to provide realistic and
achievable standards that ensure erosional stability of the landscape, provide adequate
• productivity for the postmining Land use, and establish vegetative composition end
successlonel levels sufficient to ensure continued plant community development. Because
of s number of factors, both netureL and es a result of applied current technology,
