2.05.6(3)(b)(iv) <br />(iv) The following monitoring plan is designed to <br />provide data which will verify that the Somerset Mine and the Sanborn <br />Creek Mine will not have significant adverse impacts on the surface or <br />subsurface water which is within or adjacent to the permit area. The <br />sample paints, shown on drawing E8-3286, are: <br />Station Frequency Elevation Location <br />H-1 Note 1 6100 Hubbard Creek <br />H-10 Note 1 6376 Hubbard Creek <br />B-6 Note 1 6782 Bear Creek <br />S-1 ~~ Note 3 6080 Sanborn Creek <br />S-2 Note 3 6030 Sanborn Creek <br />F-.l Note 2 6057 Portal Drop Inlet <br />U-1 Note 2 6090 Unnamed Drainage <br />C-1 Note 2 6070 Coal Gulch <br />NF-1 Note 2 6080 Gunnison River <br />NF-2 Note 2 6010 Gunnison River <br />SC-1 Note 4 6106.1.

Annually in June field parameters and full suite. <br />Full suite analysis parameters are shown on Page 2.04-39a. Field <br />parameters include flow or water level, pH, temperature and conductivity. <br />The Sanborn Creek Mine water discharge, Outfall 001, will be <br />monitored according to the NPDES discharge permit. A flow meter will be <br />installed to measure flows from the mine dewaterina system. <br />2.05 - 46iii <br />New 09-16-92 <br />
