Stover & Associates <br />2352 N. 7th St. Ste B <br />Grand Junction, CO 81501 <br />Re: Munger Canyon Mine (Permit No. C-1981-020) <br />Technical Revision 27 (TR -27) <br />Adequacy Review <br />Dear Mr. Stover: <br />After reviewing TR -27 from CAM Mining LLC, the Division has the following comments: <br />1. In the proposed revised page, the 6' paragraph, beginning "On March 20..." has been changed to refer <br />to GW -5 when previously it referred to GW -6. Please explain the reason behind the change to the text <br />of the 6' paragraph. <br />2. Rule 4.07.3 gives performance standards for the permanent sealing of all underground openings, <br />including wells. Specifically, 4.07.3(3) requires that a plugging and abandonment report should be <br />submitted to the Division within 60 days of abandoning a drill hole. Such reports are not readily <br />available in the PAP for GW -2, -4, -7 and -8. Please provide plugging and abandonment reports for <br />GW -2, -4, -7 and -8. They should be added to the PAP as a new appendix, and referred to in the text <br />of section 2.6. <br />3. Following the approval of TR -27, GW -5 and GW -6 should be plugged and abandoned in the <br />accordance with 4.07.3. Plugging and abandonment reports for the two wells should be submitted to <br />the Division within 60 days, and added to the PAP with a new Minor Revision. <br />If you have any questions, feel free to contact me at any time. <br />Sincerely, <br />Zach Trujillo <br />Environmental Protection Specialist <br />(303) 866-3567 ext. 8164 <br />Zach.Trujillo@state.co.us <br />pF COlO <br />H <br />1313 Sherman Street, Room 215, Denver, CO 80203 P 303.866.3567 F 303.832.8106 http://mining.state.co.us I <br />John W.
