Findings of those two studies were not available at the time that this adequacy review was ready for <br />release, but be advised that additional adequacy concerns may be forthcoming as a result of the fmdings of <br />those two studies, either as part of the AM-2 review process, or as additional adequacy concerns submitted <br />under separate cover. <br />Administrative <br />The deadline for the Division to render a decision on this EPP is 10 January 2011. Please provide your <br />response to these adequacy issues with sufficient time for the Division to review ahead of the decision <br />deadline. If the Operator requires additional time to respond to these adequacy issues, a written request for <br />extension must be submitted before the deadline of 10 January 2011. <br />Please be advised that the new Mineral Rules and Regulations for Hard Rock, Metal, and Designated <br />Mining Operations took effect on 30 September 2010, which has resulted in a re-numbering of some of the <br />rules that pertain to your application. <br />You may call me with questions at 303-866-3567 ext 8108 or in my absence Tony Waldron at ext 8150. <br />Sincerely, <br />a4??
