Part of TR36 updates the probable hydrologic consequences section of the permit (Section 2.05.6 of <br />the permit). A new section of this portion of the permit titled "Postmining or Interim Discharge — No. 5A and No. <br />6 Mines" is proposed to be added through TR36. <br />would like to request your assistance in reviewing this new section of the permit to determine compliance with <br />Rule 2.05.6 (3)(b)(iii). I have attached a copy of the section in question (proposed revised page 2.05 -47). <br />The site is an underground mine that has been inactive since 1995, with the exception of some surface <br />reclamation activities that occurred between 2008 and 2010. Up until last year, the operator dewatered the <br />underground workings. At this time the pump has been shut off and the underground workings are being allowed <br />to fill with water. Permit sections 2.04.6 and 2.04.7 discuss the Geologic and Hydrologic setting of the mine site <br />and are not being modified through TR36. However, the majority of sections 2.05 (operations and reclamation <br />plan) of the permit are being revised with TR36. Overall, the changes to this section are minor with slight word <br />revisions and updates to account for reclamation that has occurred at the site. A copy of the full revision is <br />located in my office should you need to reference it. Please let me know if you have any questions. <br />must provide adequacy review comments to the operator by June 11th, 2014. If I could have your comments <br />prior to that date so they can be incorporated into the adequacy review; if necessary, that would be most helpful. <br />appreciate your assistance with this review, <br />https: / /mail.g oog le.conVmai I /u /0 / ?ui =2 &i k= e29129fcb5 &viev�-- pt &search =i nbox&th= 1463f778c354f7e5 &si ml= 1463f778c354f7e5 1/2 <br />
