<br />DMG Concern <br />Items 111.6.9. and 12 were discussed and found that this information is not <br />available. CEC provided a letter from the Division dated September 12, 1986 <br />confirming information regarding the Lux well. <br />CEC Rgsponse <br />No response required. <br />DMG Concern <br />The Division reviewed construction certifications for impoundments at the Eagle <br />No. 5 and 9 Mine. These certifications were provided to the Division on September <br />2, 1993. The Division's comments follow: <br />1) The submitted drawings don't appear to be numbered for placement <br />into the permit. CEC should number the exhibits. <br />2) Rule 2.05.3(4)(a)(i)(B) requires the operator to submit cross sections <br />of impoundments. The drawing depicting the sewage lagoons <br />includes cross sections. The others, 5-P5, 5-P6, and 5-P7; 9-P2; and <br />9-P3 do not. Please provide cross sections of the ponds and <br />embankments as required. <br />3) Please provide details for the emergency spillways for ponds 9-P2 <br />and 9-P3, as required by Rule 4.05.6(7). Specifically, the Division <br />needs dimensions of the depth, width, length, and side slopes, and <br />specifics of any channel lining in place. <br />CEC Response <br />Per our meeting of March 1, CEC will provide the numbered versions of the <br />previously submitted drawings. As discussed, the cross-sections and spillways <br />information requested will be submitted under a separate letter to allow CEC time <br />to review our files and determine if any additional submittals are required. If so, <br />then CEC may need to conduct supplemental survey work on some of the sites. <br />Per our discussion, CEC is concerned that adverse ground conditions might <br />negatively impact survey accuracy if we were to attempt such surveys too early. <br />As such, CEC will provide the necessary information at a later time, in order to <br />avoid any further delays to the renewal process. Per our previous discussions, this <br />timeframe will follow the 90 day outline previously noted. <br />
