S • • 5. The requested information is contained in the application as referenced f below: quantitative estimates of water pumped daily from underground operations (page 2.05-109, Fig. 10) and surface operations (page 2.05-108); and chemical quality of.~umped mine water pages - 1, 2.05-113, 2.05- 114, and 2.05-115). 6. As stated on page 2.04-38, the effect of the fault which rune through the ~ permit area on ground water movement is to locally disrupt the piezometric tilq surface and flow of ground water, as shown on Map Ii4, Energy Mine No. 3 ~J Groundwater Hydrology. Energy Fuels has an interest in obtaining the site- specific information requested for the purposes of mine planning as well as evaluating hydrologic impacts in the fault zone. In order to obtain the requested information, an expensive and time consuming program of monitor well drilling, pump testing, water level measurements, ground water samp- ling and analysis, and application of modeling techniques in the area of the fault zone should be undertaken. However, the Middle Creek Mine is in a dormant state at this time, and a decision has not been made as to when the mine will be re-opened. In light of the present situation, it is not appropriate to require Energy Fuels to provide this information until the decision is made to re-open the underground mine. During our discussion on June 30, 1981, you stated that this information would not be required to assess possible impacts caused by surface mining, as long as mining does not intersect the fault zone. Therefore, Energy Fuels proposes as a settle- ment of this issue to commit in the application [o provide the requested information at least ninety (90) days prior to resumption of mining at the Middle Creek Mine. 7. The requested information is contained in the application as referenced below: scope of research (pages 2.05-104 and 2.05-105), locations of monitoring wells (Map ~t4, Energy Mine No. 3 Groundwater Hydrology) and results and conclusions formulated to date (pages 2.04-32 through 2.04-50, 2.05-81 through 2.05-121). -June 9 letter, Rule 2.04.5, General Description of Hydrology and Geology 1. Energy Fuels will submit a map showing outcrops of faults, major aquifers (Twentymile Sandstone and Trout Creek Sandstone), formation contacts, and coal seams with dip and strike symbols (coal information within the pro- posed permit area only). -June 9 lettec, Rule 2.04.6, Chemical Analysis of Overburden 1. As previously mentioned, Energy Fuels will submit and justify repre- sentative chemical analyses of the Lennox seam from the Eckman Park Mine and, in addition, the stratigraphically highest unit to be mined. 2. Energy Fuels will document that these chemical elements probably do not exist in the overburden at Energy Mine No. 3, using data correlated from the Eckman Park Mine.
