4.3 APPENDIX C Species Pourrda Pure Llve Variety Seed/Atres 3. Perennial crown cover is less than that measured on representative undisturbed areas. 4. Soil erasion rates on reclaimed areas exceed [hose of representative undisturbed areas. All merchantable forest products within the project development area that are taken, damaged, or destroyed will be purchased by the designated operator/lessee at the total appraisal price, to be determined by the authorized officer, Bureau of land Management (BLM), White River Resource Area. Disposal will be as follows: All stems, stumps and branches over 4 inches in diameter shall be: a) removed from federal land for resale or private use, or b) cu[ into lengths not exceeding 4 teat and scattered away from the disturbance. All stems and branches less than 4 inches in diameter shall be evenly scattered away from the disturbed area. Annual or noxious weeds shall be controlled on all disturbed areas as directed by the authorized officer. Method of control shall be by an approved mechanical method or an EPA registered herbicide. All herbicide application proposals must be under direct field supervision of an EPA certified pesticide applicator. The species mixture submitted in the mine plan for use in reclamation is amended as follows: Pounds Pure Live Species Vuiety Seed/Acres GRASSES Pubescent wheatgrass Lune Thickspike wheatgrsss Critana FORB Alfalfa Ladak • preinoculated Wherever possible, at least 12 inches of topsoil will be reapplied to disturbed areas after reconu>uring. When topsoil availability precludes a 12-inch application rate, as much topsoil as is available will be applied, but in no case will reapplied topsoil depth be less than 6 inches. Reclamation will be initiated as soon after disturbance as possible, or as directed by the authorized officer. Surface disturbing activities shall not be performed during periods when the soil is too wet to adequately support equipment. If equipment creates ruts in excess of 3 inches deep, the soil shall be deemed to be tca wet to adequately support equipment. Mud blading is not considered an alternative to meeting the criterion in this stipulation. Blading of vegetation or surface leveling of the area between wells comprising a well pair will not be allowed without prior documented authorization from the authorized OffICRI. The designated operator/lessee will be responsible for GRASSFs moni[Oring reclaimed areas for al least Three complete Thickspike wheatgrass Crilana 0.50 growing seasons after final reclamation work is completed.

Reclamation will be considered a failure and remedial measures required prior to bond release if one or more of the following conditions persist: 1. Production of herbaceous perennial species by category (forb, grass) is less than that measured on representative undisturbed areas. 2. Shrubs comprise less than 12 percent and perennial forbs less than 4 percent of I:he established plant composition by cover.
