Chip Brown, Environmental Engineer <br />April 18, 2012 <br />Dear Mr. Zuber, <br />Sincerely, <br />Chip Brown <br />Environmental Engineer <br />Enclosure <br />CC: file CF 21.1.2.2012 w \encl <br />Mr. Robert D. Zuber, P.E. <br />Environmental Protection Specialist <br />Colorado Division of Reclamation, Mining and Safety <br />Department of Natural Resources <br />1313 Sherman Street, Room 215 <br />Denver, CO 80203 <br />5731 Highway 13 <br />Meeker, Colorado 81641 <br />970 - 824 -1500 <br />RE: Pond Outfall Inspection and East Pit Stock Pond Inspections, 15t Quarter, 2012 <br />970 - 824 -1573 <br />Enclosed please find one copy of the Pond Outfall Inspection for the First Quarter of 2012 and one copy <br />of the East Pit Stock Pond Inspection for the First Quarter of 2012. Per the Division's request that <br />Colowyo submit quarterly pond inspections on a quarterly basis rather than annually, Colowyo has <br />discontinued submittal of these quarterly inspections in the Annual Reclamation Report. Any changes in <br />outfall storage capacity since the previous inspection are reflected on the 2012 First Quarter Report. <br />Please note that storage capacity for the 4th Quarter 2011 Inspection sheet does not reflect pond <br />cleaning activities performed during 2011 for Outfalls 002A, 003A, 006A, and 010A. The attached 15t <br />Quarter 2012 Inspection sheet reflects the sediment removed from 002A, 003A, 006A, and 010A during <br />2011 and subsequent estimated sediment deposition to date. <br />If you have any questions or require additional information, please feel free to contact me at (970) 824- <br />1573. <br />
