-g- <br />V. Hydrologic Balance: Surface Water (2.045, 2.047, 2 <br />A nC <br />The surface water quality, diversions, sediment control, and discharge <br />structures sections of the application have been reviewed by the <br />Division. The surface water quality portion of the permit application <br />can be found in Section 2.81, and the diversions, sediment control, and <br />discharge structures sections can be found in Volumes IV, V, and VI. <br />The proposed operation is in compliance. <br />VI. Hydrologic Balance: Ground Water (2.04.5, 2.04.7, 2.05.3(4 <br />In order to insure the applicant has adequate baseline data prior to <br />mining outside the five year permit area the following stipulation <br />(included in the original permit) is required: <br />Stipulation No. 1: THE APPLICANT MUST INSTALL MONITORING WELLS IN, <br />CONDUCT PUMPING TEST ON, AND MONITOR WATER LEVELS AND WATER QUALITY <br />IN THE ALLUVIUM OF DRY FORK, LICK CREEK, SOUTH PRONG AND HORSE <br />CREEK ONE YEAR PRIOR TO MINING WITHIN THE WATERSHEDS OF THESE <br />STREAMS. THE APPLICANT SHALL SUBMIT TO THE DIVISION THE DATA AND <br />RESULTS OF THESE TESTS AND MONITORING ALONG WITH PROJECTED IMPACTS <br />PRIOR TO CONDUCTING MINING WITHIN ANY OF THE WATERSHEDS. <br />VII. Alluvial Valley Floors (2.06.8, 4.24) <br />Identification of Alluvial Valley floors <br />The applicant has identified four areas within or adjacent to the mine <br />plan area which may meet the geomorphic criteria of alluvial valley <br />floors. Alluvial deposits were identified along Minnesota Creek, Dry <br />Fork Minnesota Creek, Sylvester Gulch, and the North Fork of the <br />Gunnison River (Exhibit 2.8.4.6). <br />Two of these areas, Minnesota Creek and Dry Fork Minnesota Creek, <br />although geographically adjacent to the permit area, are not <br />hydrologically adjacent to the activities being reviewed in this permit <br />application. Both a surface water divide and aground water divide <br />(Exhibit 2.8.2.A) separate these areas from the mining activities being <br />permitted. Agricultural areas currently exist along Minnesota Creek, <br />and the area is probably an alluvial valley floor. However, a formal <br />determination for either of these two areas will not be made at this <br />time. When the applicant submits an application that proposes mining <br />activities within either the surface watershed or ground water system <br />for these areas, the Division will make the required alluvial valley <br />floor determinations. <br />
