Forrest Luke, TMI <br />Page 4 <br />7/29/2014 <br />b. For the expansion area please update the surface water information contained in permit <br />section 2.7.4 with the information required from Rule 2.04.7(2)(a) and (2)(b)(1). <br />i. Trapper's Response: The surface water regime of the expansion area is similar to <br />the existing permitted mine area. Enclosed Table 2.7 -12 of section 2.7.4 has been <br />updated with new information in regard to the expansion area. The remaining <br />discussion within section 2.7.4 is still applicable to the expansion area. Enclosed <br />revised Map M -51 (sheet 3) and Map M -31 (included in the original PR -7 <br />submittal) depict relevant surface water courses and surrounding water resources in <br />the area. Prior studies and information gathered on the characteristics of the <br />surface water regimes of the Williams Fork Mountains would pertain to the <br />expansion area. Trapper will submit additional relevant information as needed <br />once monitoring of the affected drainages is conducted. <br />ii. Division's Response: The minimum surface water information required in <br />accordance with Rule 2.04.7(2)(b)(1) is the minimum, maximum and average flow <br />which identify critical low flow and peak discharge rates of streams sufficient to <br />identify seasonal variations. Trapper has identified two additional subdrainage <br />basins within the expansion area; Deacon and Jeffway. For surface water within <br />these subdrainage basins, Trapper will need to submit the information required by <br />Rule 2.04.7(2)(b)(1). If new surface water monitoring sites are established, map <br />M30 will need to be updated. <br />iii. Trapper's Response #2: Permit page 2 -4141 has been updated with current <br />preliminary baseline information for Jeffway and Deacon Gulch. Further <br />information relevant to this section will be added as it is obtained. Map M30 <br />will be updated at a later time when observation flumes are installed. <br />iv. Division's Response: This item is considered resolved. <br />11. For the expansion area, please submit a map that depicts the location and extent of sub - surface <br />water, if encountered within the proposed permit and adjacent areas, including but not limited <br />to areal and vertical distribution of aquifers, and an estimate of seasonal variations of aquifer <br />characteristics on cross section and contour maps as appropriate; in accordance with rule <br />2.04.7(4)(c). <br />a. Trapper's Response: The required information will be contained within the upcoming <br />2013 Annual Hydrology Report. The location and extent of sub - surface water will be <br />included in the Water -Level Elevation maps in the 20 13 AHR. The proposed new permit <br />
