-36- <br />Stipulation No. 10 attached to the initial 5-year permit required the <br />permittee to submit information to the Division demonstrating that pre-mine <br />vegetation sampling data was representative of what may be expected from <br />present vegetative communities. The operator subsequently submitted an <br />adequate response, thereby satisfying the requirements of the stipulation. <br />Stipulation No. 11 attached to the initial 5-year permit required the <br />permittee to supply the Division with woody plant density data for all sampled <br />communities. This information was required in order to determine whether the <br />affected and reference areas of similar plant community, at the McClane Canyon <br />and Munger Canyon mine sites could be combined to yield an adequate sample <br />which could then be used as a standard for the woody plant density component <br />of revegetation success. Several tests were performed to determine the <br />comparability of affected and reference areas, and Munger and McClane <br />communities. It was determined that the means of Big Sagebrush affected and <br />reference areas were equivalent at 95% confidence (alpha=2). All other <br />communities (Greasewood, Shadscale, and Juniper) did not show equivalency <br />between affected and reference areas. Data from the Big Sagebrush affected <br />and reference areas was combined to yield satisfactory baseline data for woody <br />plant density for the Big Sagebrush community. Stipulation No. 11 to the <br />September 7, 1982 findings document is considered resolved. <br />Revegetation Plan (2.05.4(2) (e)) and Revegetation Success (4.15) <br />The Division has reviewed the Munger Canyon Mine revegetation plan and <br />revegetation criteria (Sections 3.4 and 4.5.12 of Volume I and Section 3.3 of <br />Volume VI of the application). In the original permit application, the <br />applicant proposed a variance from baseline woody plant densities for the <br />Greaswood shrubland, Big Sagebrush, Shadscale shrubland and Pinyon-Juniper <br />communities, but did not provide justification for the proposed stocking <br />level. As a result, the Division attached a stipulation to the original <br />permit requiring justification for the proposed woody plant density <br />revegetation levels. The applicant submitted responses to the stipulation on <br />August 4, 1982 and April 8, 1983. The responses provided additional <br />information on shrub densities necessary for adequate wildlife habitat but did <br />not conclusively justify the stocking levels proposed by the applicant. <br />Therefore, based on a review of this information and consultation with the <br />Colorado Division of Wildlife, the following stipulation is required: <br />Stipulation No. 9 <br />THE FOLLOWING WOODY PLANT DENSITY REVEGETATION SUCCESS STANDARD IS PROPOSED BY <br />THE DIVISION FOR THE MCCLANE CANYON MINE: 500 STEMS/ACRE FOR THE GREASEWOOD <br />SHRUBLAND, BIG SAGEBRUSH AND SHADSCALE SHRUBLAND COMMUNITIES, AND 1500 <br />STEMS/ACRE FOR THE PINYON-JUNIPER COMMUNITY. WITHIN 60 DAYS OF PERMIT <br />ISSUANCE THE PERMITTEE SHALL EITHER REVISE THE PERMIT APPLICATION TO COMMIT TO <br />USE OF THIS STANDARD OR COMMIT TO USE OF AN ALTERNATE STANDARD AGREED UPON IN <br />CONSULTATION WITH THE DIVISION. <br />
