Spillage <br />Snowmass' operations have been designed to minimize spillage. <br />Nevertheless, spillage may occur on occasion. Any spills or accumula- <br />tion of fines that occur will be cleaned up and hauled to the refuse <br />disposal area where they will be buried. All spills will be cleaned <br />up at the mine and loadout prior to final reclamation of the refuse <br />disposal area. <br />Revegetation Plan <br />Hand-plantings of woody species are the most important aspect of the <br />revegetation work. Seeding of herbaceous species will be used to pro- <br />vide early established cover in the short term and some diversity of <br />permanent understory vegetation in the long term. Species and seed <br />mixtures proposed here for final reclamation will be used for interim <br />reclamation efforts (see Tables 4.4.2-1 through 4.4.2-4). Rased on <br />• the results of these efforts, these combinations may be modified <br />before the beginning of final reclamation. Also, 20 years from now, <br />plant selections and varieties will be available for reclamation which <br />are not available now. The last several years have indicated that due <br />to changes in regulatory requirements, reclamation technology and <br />experience, and species availability, recommendations for seed mix- <br />tures which are more than 2 to 3 years old are probably obsolete. No <br />changes will be implemented without prior approval of the Division. <br />The revegetation of the mine area is intended to provide a cover of <br />predominantly native species compatible to the area and to postmining <br />land use. Some of the native species proposed may not be indigenous <br />to the immediate area but should otherwise be adapted; some of the <br />exotics proposed may already be indigenous. Of the shrubs already <br />tried, Russian olive has shown the most promise. It is a drought- <br /> <br />4-54 <br />
