<br />-2- <br />Wolf Creek Overburden aquifer water quality and quantity was minimally < <br />discussed in the application, as CYCC deems the aquifer insignificant {j~ . <br />due to unsustainable yield from existing wells. Pi ease provide all <br />water quality and water monitoring data acquired to date from existing <br />wells (85-1 W, 85-2W, 85-3W, WC-5 and WC-6) as well as any documentation <br />on the physical characteristics of this overburden as an aquifer <br />(transmissivity, yield, saturated thickness, storage coefficient, <br />permeability, effective porosity and vertical permeability). This will <br />provide the Division with necessary supporting information. <br />~4. Please make Figure 1 and Map No. 12 which show the ground water and ~~`- <br />surface water basins consistent with one another. Figure 1's ground <br />water basin outline appears to be inaccurate along the northern <br />boundary, and should be corrected. <br />Geology Description - Rule 2.04.6(1)(b) <br />~/1. Rule 2.04.6(1)(b)(i)(c) requires data which documents the physical D~` <br />properties of each stratum within the overburden including texture, <br />swell and other information sufficient to determine the compactibility, <br />erodibility and an overall estimate of overburden and interburden <br />swel]. The applicant states that this information is available in <br />permits associated with adjacent tracts on page 2.04-19. Please give <br />specific references to these permits including Table numbers, Exhibit <br />numbers and pages. <br />f2, Overburden drill logs were presented in Exhibit 8 which referenced <br />Maps 7A and 76. Some wells in Exhibit 8 were not located on the maps <br />while other wells listed on Maps 7A and 78 had no drill logs. Please <br />make these two sources of information compatible. Below is a listing <br />of the requested information. <br />Additional Information Needed to Complete Exhibit 8 <br />026-80-9 <br />026-80-12c <br />026-80-24 <br />026-81-01 <br />026-81-02 <br />026-81-07c <br />026-81-26 <br />026-81-33c <br />026-81-34c <br />026-82-30 <br />026-84-32 <br />026-84-36 <br />DH-1 <br />DH-2 <br />Location <br />Drill Log <br />X <br />
