Walther <br />Executive Director <br />Michael B. Long <br /> Division Director <br />RE: Change in Pond Operational Procedures, TR~S <br />New Elk Mine, #C-81-012 <br />Dear Mr. Koblitr: <br />The Division of Minerals and Geology has completed review of technical revision no. 45 <br />(TR-45) for New Elk mine. As a result of this review, we have the following questions or <br />comments. <br />Please submit the watershed map(s) used to determine all sub-watersheds for <br />the SEDCAD analysis done on both pond 5 and pond 7. <br />2. Permit text on page 2.05-10a should be modified and/or corrected as follows: <br />^ ".5 mg/I"should be changed to ".5 ml/I" <br />^ Text language should read something to the effect "...modeling indicates sediment <br />effluent limitations can be met..." and that "...sampling of pond discharge in <br />accordance with the approved CDPS permit will determine actual compliance with <br />limitations..." <br />If you have any questions, please call me. <br />Sint rel , <br />nt A.
