bond release. The conveyor at the loadout occupied at portion of the Roazing Fork River AVF. The conveyor had been built prior to the enactment of the alluvial valley floor regulations for underground mines. Thus, restoration of flood irrigation was established at the time the initial permit was issued as the only criterion for restoration of the hydrologic function. Phase III The remaining portion of the bond amount shall be released when the permittee has successfully completed all surface coal mining reclamation operations in accordance with this approved reclamation plan, and the final inspection and procedures have been satisfied. This shall not be before the expiration of the period spec f ed for revegetation responsibility. Cover An extended reference area is used to compaze reclaimed mine azeas to undisturbed native communities at the North Thompson Creek Mines. For vegetative cover, the revegetated area shall be considered acceptable if it is not less than 90 percent of the cover as determined from the reference azea. Vegetation cover on the reference area was measured in 2000 as 30.1 %. Vegetation cover on the reference area was measured in 2001 as 30.4%. Thus, the cover standazd for revegetated areas was 27.1 % in 2000, and 27.4% in 2001. Production For herbaceous production, the revegetated rangeland area shall be considered acceptable if it is not less than 90 percent of the production as determined from the reference area with 90 percent statistical confidence. Herbaceous production on the reference azea was 13.6 grams per half square meter in 2000. Thus the required 2000 production was 12.2 grams per half square meter. Herbaceous production of the reference azea was 8.7 grams per half squaze meter in 2001. Thus, the required 2001-production was 7.8 grams per half squaze meter.- Diversity Species diversity on the combined natural communities will be considered acceptable if sampling demonstrates that four perennial non-noxious plant species have been established and are contributing between 3% and 60°lo relative cover. At least two species should be grasses and at least one should be a perennial forb or shrub. Woody Plant Density Woody plant density as a criterion for reclamation success was waived at the request of the landowner, with the concurrence of the Colorado Division of Wildlife, via Technical Revision (TR) 20. This TR was approved by the Division on October 1, 1998. SL-O5, C-81-025, March 24, 2003 Page 11 of 26 Pages
