A boring log, well completion details, water levels, and an initial water quality <br />analysis will be submitted to DBMS within 90 days after well completion. <br />Subsequent monitoring data will be included in the annual report for the facility. <br />Energy Fuels will notify DBMS and the BLM within 30 days of receiving sample <br />results if the analyses indicate deterioration in water quality compared to the <br />established baseline data. If this were to happen, Energy Fuels would evaluate ground <br />water conditions and propose suitable mitigation measures. <br />8) The intermittent operational history of uranium mills, and reported problems at the <br />White Mesa Mill (J. Burnell, personal communication, Oct. 24, 2007), suggest a <br />potential shortage of uranium processing capacity in the near future. In such an <br />event, does EFRC have provisions for on-site stockpiling of ore for extended time <br />periods, or would the mine suspend operations? <br />Based on our discussions with Denison Mines, Energy Fuels anticipates that the <br />White Mesa Mill will go into production at a milling rate of 1,500 tons per day during <br />the first half of 2008. It is very unlikely that benison's mines can produce this <br />amount of ore and we anticipate that they will be amenable to purchasing additional <br />ore to meet their milling needs. Energy Fuels plans to mine approximately 10,000 <br />tons of ore during 2008 (see attached production schedule in Attachment D). The <br />proposed ore pad has capacity for 15,000 tons of ore; therefore, we have ample <br />storage capacity on site during the first year of operations in the event that Denison <br />has difficulties in restarting their mill. <br />9) As stated above, due to the emplacement of underground bulkheads as part of the <br />reclamation plan, there is a concern about post-mine discharge from new springs <br />other than from the mine workings. After looking at the newly provided post-mining <br />bulkhead installation plan, there is also concern about adit discharge. The applicant <br />states that the bulkheads will be placed "to ensure that water seeping into the decline <br />from the lower Brushy Basin aquifer is not allowed to enter the mine workings. " <br />However, as hydraulic head builds up behind the bulkheads, what is the possibility of <br />ground water migrating via fractures or along bedding planes back into the workings <br />ahead of the bulkhead? This perhaps should also be considered in light of the <br />possibility of Colorado moving out of the long-term drought conditions that it is <br />experiencing, and enters conditions that result in re-charging of aquifers and <br />elevated water tables in that part of the state. <br />Energy Fuels conducted additional geological inspections of the Whirlwind Decline <br />and have identified an excellent location for installing the underground bulkhead. <br />This proposed bulkhead location is near the bottom of the decline in the extreme <br />upper portion of the Salt Wash sandstone unit (see Figures Fl and F2 in Attachment <br />E). The sandstone is fine-grained, non-mineralized, and of low hydraulic conductivity <br />and high compressive strength (see Items 4 and 20 for related information and <br />Attachment B for sandstone test results). There are no observed bedding planes or <br />fractures in this sandstone that could serve as conduits. <br />1=~.ncz~~~~ 1='ue(s Eesotlr-eeti Cc>rpc~ratio~~ =1~ l.l~~~i~~~~ Pc>txl~;tr~-~~•d.
