Cottony <br />Division Dirett?r <br />Natural Resource Trustee <br />As requested, I have reviewed western Fuel-Colorado's ?wFC' } TR-??. with this revision wFC <br />is proposing to reinstate several groundwater n?orutoring welly back into the approved groundwater <br />monitoring plan and also requests to lower the ?axnpling frequency to annual at five surface water <br />sampling sites. I have the following adequacy review comment, which could be forwarded directly <br />to the operator. <br />I . Cn revised page x.04.7-? 1 under Tuttle Draw, reference iS made to stream flov?r information <br />and. that it can be found in ?oXuine B ofNew ?ori?on 1 Reclamation Plan. There is no <br />stream flow discussion provided for Tuttle Draw in the current permit document, This is <br />important information in understanding the rationale for the surface water sampling plan at <br />Yoffie Draw. Rather than referenced, the pertinent informatioi regarding flows in Tuttle <br />Draw should be sunarriari?ed and incorporated in to the current permit volume an page <br />x.04.7-31, <br />?, ?n the bottom ofpage ?.04.7?3?, wFC states "the temporary pipeline will be ren?aved in <br />the year ?00G when the mining progress eliminates the need for irrigation water in <br />advance ofthe mine." This appears to be outdated and should be updated accordingly. <br />3. 7n the last paragraph. of page x.04,7-45 ail discharging NPDE ?utfalls ?-l02} are <br />listed for sampling on a quarterly basis according to the parameters listed in Table 2.04.7- <br />?.
