seam to be spoiled (a rough estimate is 5X or less of the total overburden in
the area to be mined), and the fact that the Lennox has been spoiled at this
mine and other operations in the immediate area in the past with little
apparently related problems, the lack of site-specific data for the Lennox
should not be considered as an adequacy concern.
1. Drill hole logs are presented in Exhibit 1. A number of logs for
monitor wells that are included in the applicant's Hydrologic Monitoring Plan
(Exhibit 15, Table A) are not contained 1n Exhibit 1. Specifically, drill
hole logs for the following monitor wells are missing: 77-35; 77-42; 77-43;
79-6; 79-7; and AX-1. Drill hole logs for these monitor sites should be
included in Exhibit 1.
VI. Hydrologic Balance - Rules 2.04.5, 2.04.7, 2.05.3(4), 2.05.6(3) and 4.05
A. Ground Water Information
Ground water information within the permit application is found to Section
2.04.7 of Volume 1. Additional information is found in Map 1, Twentymlle Park
Hydrology, Map 4, Mine No. 3 Hydrology, Map 17, Stream Channel Cross Sections,
Tables 26 and 30, and Figures 6 and 8.
1. The potentiometric surface of the overburden and alluvial aquifers 1n the
permit area are presented on Map 4, Mine No. 3 Hydrology. These contours were
drawn based on October 1980 water level data. The map should be updated to
reflect more current ground water level information and should include water
level data from all bedrock and alluvial monitor wells.
2. Ground water quality data from the proposed permit area are presented in
Tables 26 and 30 of the permit application. The data presented in these
tables do not reflect the total ground water sampling and analysis effort
conducted to date at the Energy Mine No. 3 site. Additional historic data for
both bedrock and alluvial monitor wells is contained in Tables 26 and 30 of
the original Energy Mine No. 3 permit application submitted by Energy Fuels
Corporation in February, 1961 (CMLRD file No. C-036-81).
All pertinent ground water level and ground water quality data (i.e. all
available historic data from sampling points that are Included to the
applicant's proposed Hydrologic Monitoring Plan) should be compiled into the
present permit application.
3. Ground water monitor well 08-FM-6 is identified on Map 4 as an alluvial
aquifer monitor well. This well is identified as a deep aquifer monitor well
1n Table A of Exhibit 15 (Hydrologic Monitoring Plan). This discrepancy
should be corrected. If this well is a dual completion, it should be
identified as such.
4. A typographic error on page 2.04-41 of Volume 1 may lead the reader to
some confusion in calculating the recharge rate of the overburden aquifer.
The amount of water available for ground water recharge should be 3.2 Inches
per year, not .2 inches as 1t appears on page 2.04-41.
