A list of water quality parameters to be analyzed every 6 months in stormwater runoff <br />from the site will be included in the Stonnwater Management Plan. As discussed in our <br />response to Comment 7 above, this plan will be added in an appendix to the Plan of <br />Operations. The water quality parameters will, at a minimum, include the inorganic <br />analyses specified in our discharge permit for the water treatment system. These analyses <br />do include total suspended solids (TSS). <br />1 S. Page 8-26: Re: possible placement of ore in collection ditches: Flagging or other <br />demarcation used to contain ore pile to avoid this scenario? We want to prevent this from <br />happening. <br />Energy Fuels requires that all low-grade ore be placed in the ore stockpile area where it is <br />blended with higher grade ore to achieve a uniform grade of 0.020% U3Og or higher. The <br />entire ore stockpile area will drain to the Untreated Water Tank; accordingly, no flagging <br />or demarcation is needed. The statement on Page 8-26 refers to ore-bearing rocks up to <br />one foot in diameter that could be mixed in with the waste during split shooting and <br />loading operations. These rocks, fortunately, can be readily identified by their darker <br />color. Historically, when labor rates were much lower, it was not uncommon for a young <br />miner starting out at a mine to be given the job of combining through the waste dump to <br />find these types of ore-bearing rocks. The material that was then added to the ore <br />stockpile. Obviously, this cannot be done today; however, it is possible to have the <br />collection ditches walked on a regular basis and after major storm events to identify <br />potential problems such as breaches, silt build up, and the presence of ore-bearing <br />materials. If acceptable to the BLM, this requirement would be added to the SWMP. <br />16. Page 8-27: BLMwould like to see weekly water quality monitoring results. <br />Under the provisions of our discharge permit, we are required to sample treated water <br />weekly and provide these results to the DWQC monthly (i.e., by the 28th day of the <br />following month). These results are submitted on Discharge Monitoring Report forms, <br />commonly referred to as DMRs. Three copies of the forms are produced. Energy Fuels <br />will send one of the three copies to the BLM each month. This reporting requirement will <br />also be added to the referenced text in the Plan of Operations. <br />17. Page 13-1: BLM has a rain gauge in Cave Canyon, with about 25 years of data. <br />These data are available for inclusion. <br />The rain gauge data was received from the BLM by Greg Lewicki and Associates and <br />will be incorporated into Exhibit 13. <br />18. Any statements proposing that downed trees would be separated into piles and made <br />available for firewood collection must be revised to state: <br />Downed trees and all other woody material will be paced on top of the topsoil during <br />reclamation, either as mulch or in whole pieces. <br />'!"tG7~~!~y' ~~i1~'~`~ ~1Cti6~LtF~'.'S E. i~t"}'rE)i'~#I1l~tl ~~'~ ~~Ill{kli l~i)llic'ti'~311.~. 4i(tt1~' 4~t~(.~ O <br />
