Trapper's Response: Enclosed find a new M54 map series that includes the <br />requested information [Map M54D (QR Aquifer), Map M54E (KLM Aquifer), <br />Map M54F (HI Aquifer), Map M54G (20 -Mile, 2"' White and 3' White Sandstone <br />Aquifers and Alluvial Aquifer) and Map M54H (U Aquifer)]. Table of Contents <br />pages iv -4 and iv -5 are also enclosed. Page iv -4 is revised; page iv -5 is a new page. <br />11. For the expansion area, please submit a map that depicts the location and extent of sub - surface water, if <br />encountered within the proposed permit and adjacent areas, including but not limited to areal and <br />vertical distribution of aquifers, and an estimate of seasonal variations of aquifer characteristics on cross <br />section and contour maps as appropriate; in accordance with rule 2.04.7(4)(c). <br />Division's Adequacy #4 Comment: Trapper submitted revised M54 series maps depicting <br />ground water elevations for some of the aquifers within the permit and proposed expansion area <br />for the "SS ", HI and the QR aquifers. It is unclear which aquifer the map designation "SS" is <br />depicting since there are three different sandstone aquifers within Trapper's permit area. The <br />areal and vertical distribution of the 2' White Sandstone, 31 White Sandstone and 20 Mile <br />Sandstone aquifers will need to be depicted. Water elevation maps were not submitted for the <br />alluvial aquifer, the "KLM" aquifer, or "U" aquifer. Please submit maps for the aquifers cited <br />above for the expansion area. <br />Trapper's Response: See Trapper's response to No 8.a. above. <br />4.08.1 Surface Water <br />23. Trapper did not submit detailed designs for post- mining drainage channels, as required by <br />Rules 2.05.3(4),4.05.3(l), 4.05.3(1)(e), 4.05.3(7). <br />Trapper's Response: This issue is still pending discussions between the Division and <br />Trapper concerning the consultant's study. <br />2.05.3 Operations Plan — Permit Area <br />Division's New Comment. Based on Trapper's 2013 annual reclamation report, Trapper <br />identified a discrepancy in the accounting of cumulative disturbed acreage at the site. Based on <br />this the Division conducted a review of the permit to determine compliance with Rule <br />2.05.3(2)(a). Please address the following items: <br />I. Section 3.1.4.1 of the permit discusses the mining sequence. Map M4, M I OA and M l OB depict <br />the disturbance area boundaries for the next permit term. Rule 2.05.3(2)(a) requires the <br />maximum acreage proposed for each phase of the operations within the permit area be specified. <br />For each pit area that has been disturbed and is proposed to be disturbed, please indicate the total <br />area that has been disturbed and the maximum area to be disturbed during the 2013 -2017 permit <br />term. <br />II. Related to the item above, please specify the total disturbed acreage for the site in section 3.1.4.1 <br />of the permit. This acreage should be the total cumulative disturbed area acreage to date less the <br />area that has been Phase III bond release; plus the total proposed disturbance area for the 2013- <br />
