C-1981-022 <br />RN-05 Findings <br />February 2009 <br />held down with netting will be used as a means to meet soil stabilization requirements <br />(4.15.4). <br />Methods to measure herbaceous cover and production are discussed in Appendix H of <br />the permit application. The methods follow those suggested in the DMG Bond Release <br />Guideline, 1995. The Division has granted Oxbow Mining's request for the elimination <br />of the woody stem density standard for the reclamation of the mine site. The Division <br />has approved these techniques (4.15.7(1)). <br />4. Species diversity will be determined successful for bond release areas greater than 10 <br />acres when at least four perennial species have a relative cover between 3% and 60%. <br />Of the four species at least one will be a forb or shrub, and applicable perennial grasses <br />will be cool-season species. Species diversity for areas less than 10 acres will be <br />determined successful when at least three perennial species will have a relative cover <br />between 1% and 60%. Of the three species, at least one will be a forb or shrub, and <br />applicable grasses will be cool-season species. <br />Comparisons between reclaimed and undisturbed areas, in order to demonstrate that the <br />success criteria of 4.15.8, 4.15.9, or 4.15.10 have been met, will be based on the <br />following: <br />1) Comparison of cover and production on most revegetated areas with reference <br />areas established during the baseline vegetation study. <br />2) Standards for the small riparian community at the lower Hubbard Creek site which <br />include 44.3 percent cover and 1,784 pounds per acre. The diversity standard for <br />the riparian community will be as follows: The plant community shall contain a <br />minimum of one cool-season, sod-forming grass and three cool-season bunch <br />grasses with each species having a minimum of five percent cover. <br />The Division has approved these comparisons and standards. <br />6. The Division proposes to approve of the reference areas, which the applicant has <br />selected based on the requirements of Rule 4.15.7(3). <br />7. The reference areas will be utilized to determine revegetation success in a manner <br />which the Division finds acceptable 4.15.7(4)). <br />IX. Protection of Fish. Wildlife and Related Environmental Values <br />Fish and wildlife habitat is a planned post-mining land use. The applicant has selected <br />appropriate plant species and distributions to benefit fish and wildlife (4.18(4)(i)). <br />28
