July 3, 2011 <br />Mr. Jared Ebert <br />Environmental Protection Specialist <br />Colorado Division of Reclamation, Mining, and Safety <br />1313 Sherman Street, Room 215 <br />Denver, CO 80203 <br />Dear Mr. Ebert: <br />TRAPPER MINING INC. <br />RE: Trapper Mining Inc., Permit C -81 -010 <br />Second Quarter 2012 Sediment Pond Inspections <br />Impoundment Inspection results for the second quarter of 2012 are enclosed. All impoundment <br />inspections were conducted by a qualified impoundment inspector. Inspections took place on June 12 — <br />June 14, June 18 and June 19. <br />Maintenance items noted during the inspections were as follows: <br />1. No Name #5 needs to be cleaned. <br />2. Johnson #7R needs to be cleaned. <br />3. Johnson #8 needs to be cleaned <br />4. Johnson #10 needs to be cleaned. <br />5. West Pyeatt #1 needs to be cleaned and a sediment marker installed after it is cleaned. <br />6. Oak #1 needs to be cleaned and a sediment marker installed after it is cleaned. <br />Trapper will address these maintenance items in a timely manner. <br />Data related to pond capacity is attached. The last column on the table provides an estimate of the <br />remaining capacity in each pond where remaining capacity is defined as the volume remaining after <br />considering the estimated amount of sediment noted during the inspections. <br />In your response to the first quarter 2012 sediment pond inspections, dated May 24, 2012, you asked that <br />two issues be addressed. The first issue was to address the discrepancy for the percentage of sediment <br />in Coyote Pond. On July 29, 2011 Mr. Robert Zuber inquired about the same issue. I responded to his <br />letter explaining the discrepancy on August 5, 2011. He replied with a suggestion in a letter on August 8, <br />2011. I have attached a copy of all three letters for you to review. The contractor who conducted the <br />Coyote inspection was not informed of reporting the sediment as Mr. Zuber had advised. This inspector <br />will be advised of this matter. <br />The second issue addresses the accuracy of the sediment levels for the first quarter inspection. Trapper <br />has been using the same contractor, for several years, to conduct the first quarter inspections. Should <br />snow or ice cover the ponds, it is difficult for him to estimate the sediment level, so he lists the sediment <br />percentage as minimal. For future inspections, this contractor will be advised to list the weather <br />conditions that may hinder his sediment estimates. <br />Please contact me if you have any questions. <br />.... p,RIE p ;� c1' <br />F• . <br />O' <br />:° 43864 t. c : <br />moo: /3/) <br />'* <br />N/I /lilt f 111111\ \ \ \\ <br />Sincerely, <br />= <br />Tonia arie Perkins <br />CO PE 43864 <br />C F Luke /EQ file 118 7 <br />P.O.
