Russell Means RECLAMATION MINING it SAFETY <br />Environmental Protection Specialist <br />Division of Reclamation, Mining and Safety <br />101 South 3rd Street, Suite 301 <br />Grand Junction, CO 81501 and via email to Russ.Means@state.co.us <br />RE: Nuvemco, LLC's Monogram Mine, File No. M-1978-222UG <br />Conversion CN-01, Response to Final Issues <br />Dear Mr. Means, <br />We received your letter dated April 13, 2009 regarding final issues prior to decision on the Monogram <br />Mine permit conversion. I have responded to Allen Sorenson's review under separate cover stating that <br />Nuvemco will defer design on ore runoff retention design and we are in the process of re-designing the <br />sediment trap/detention pond. <br />Sue Carter with Nuvemco has sent a written acceptance of the final reclamation liability estimate for the <br />Monogram Mine. They are in the process of obtaining the bond and anticipate submitting it concurrent <br />with the new design for the staging area detention pond. <br />Nuvemco would also like to have this permit classified with intermittent status in accordance with Rule <br />1.13.7. The reason for this request is that seasonal conditions, market fluctuations or milling contracts <br />could potentially restrict mining for 180 days or more. Nuvemco will adhere to all the requirements of <br />Temporary Cessation of the mining operations. <br />Again, we appreciate your assistance in processing Nuvemco's Monogram Mine conversion to a DMO on <br />their patented mining claims and the Monogram Mine.. <br />Sincerely, <br />O&G Environmental Consulting, LLC <br />E.
