- 11 - tions. It was verified statistically that the McClane and Hunger respective communities were not significantly different in terms of vegetative productiv- ity within the bounds of each vegetative community. Data from the McClane and Munger sites were combined (within communities and between sites), and it was determined that the combined data met confidence level requirements. Due to the small area of disturbance at the 1icClane site, the CMLRD Sas deter- mined that premine productivity and premine cover data may be applied as rec- lamation success criteria. It was also determined that the productivity data for the reference areas for the McClane Canyon vegetative communities did not meet sample adequacy requirements and required stipulation (see preferred alternative section). - The applicant has not demonstrated that adequate woody plant density sampling has taken place at the McClane Canyon site and required stipulation (see pre- ferred alternative section.) The applicant has proposed a variance from baseline woody plant densities for ' the greasewood shrubland and ihe.sluidscale shrubland, but:~-has not provided justification for the proposed stocking level, and is therefore stipulated :ez;..` (see preferred alternative section). ~-. The permittee has measured species diversity in terms of species richness and species equitability but has not proposed a means to evaluate revegetatian success in terms of species diversity. ClII.RD is concerned with the. ability of Salt Creek Mining Company to reclaim - ~" the area given the low annual precipitation and subsequently stipulated it for the compliance. _ • It has determined that no threatened or endangered species of plants exist at the McClane Canyon site, based on information supplied by the applicant. Fish and Wildlife ~ '. - CtiLRD has consulted with Division of Wildlife personnel who are familiar with the area. Both agencies agree that there is little potential for adverse ef- fects of the mine on wildlife since nearly all of the anticipated surface dis- turbance has occurred and a very limited area is affected. Backfilline and Cradi Because the mine is an underground mine, only a limited area of surface dis- turbance will require backfilling and grading. A11 portals and the sediment pond will be backfilled. The coal seam will be completely covered with backfilled material. Drainage will be restored to ap- proximate pre-mining conditions. • If underground development waste is generated during mining it vill~be retain- ed in the mine workings. .: i •.
