DIVISION OF RECLAMATION, MINING AND SAFETY <br />Department of Natural Resources <br />1313 Sherman St., Room 215 <br />Denver, Colorado 80203 <br />Phone: (303) 866 -3567 <br />FAX: (303) 832 -8106 <br />Mined Land Reclamation <br />November 28, 2011 <br />Mr. Ben Miller <br />Alma Placer Company <br />2040 W. Hamilton PI. <br />Sheridan, CO 80110 <br />Re: Notice of Deficiencies <br />London Butte Underground Exploration, NOI File No. P -2011 -029 <br />Dear Mr. Miller: <br />STATE OF COLORADO <br />Item number 1 in your consultant's (Ben Langenfeld's) letter of October 24, 2011 <br />indicates that 2000 tons of material will be removed from the adit. Item 9 in the letter <br />indicates the waste material removed from the adit will be placed on a stockpile north of <br />the adit on the existing historical dumps. Item 9 also indicates the toe of the stockpile <br />will be located at least 50 feet from Mosquito Creek, and a trench roughly one foot deep <br />will be excavated surrounding the waste pile area for capturing any surface water runoff. <br />The DRMS believes the above - described measures appear adequate for protecting the <br />drainage system from pollution if the material has low acid - producing potential, but the <br />measures may be inadequate if the material has high acid - producing potential. Please <br />commit to determining the acid - producing potential of waste material extracted from the <br />adit, prior to beginning placement of the material in the stockpile. Also, please describe <br />a contingency plan for disposing the material in a manner that protects the drainage <br />system from pollution, if the material has high acid - forming potential. <br />The letter of October 24, 2011 says that a check for the financial warranty was attached, <br />but DRMS records do not show receiving such a check. Could you please verify that a <br />check was attached. <br />Sincerely, <br />7 lc- <br />Tom Kaldenbach <br />Senior Environmental Protection Specialist <br />cc (via email): Ben Langenfeld, Greg Lewicki and Associates, PLLC <br />COLORADO <br />D I V I S I O N O F <br />RECLAMATION <br />MINING <br />---- &— <br />SAFETY <br />Office of Office of <br />Denver • Grand Junction • Durango Active and Inactive Mines <br />
