J • • ^III III III III IIII III <br />999 <br />~~~~`~ STATE OF COLORADO <br />Roy Romer, Governor <br />DEPARTMENT OF NATURAL RESOURCES <br />MINED LAND RECLAMATION DIVISION <br />FRED R. BANTA, Dlnetor <br />July 7, 1988 <br />Mr. Rick Mills <br />Colorado Yampa Coal Company <br />29588 Routt County Road No. 27 <br />Oak Creek, Colorado 80467 <br />Re: Review; Annual Hydrologic Report (Water Year 1986-1987) - C-81-071 <br />Dear Mr. Mills: <br />We have completed our review of the Eckman Park, Mine 1 and Mine 2 Annual <br />Hydrologic Report (AHR) for the 1966 to 1987 water year. The evaluation <br />includes an assessment of sampling frequency, and it appears that some of the <br />required monitoring was not completed. <br />The sampling results are also discussed, and some general recommendations are <br />made pertaining to report format details. <br />Sampling Frequency <br />As stated above, several of the sampling requirements were not met <br />during the 1986-1987 water year.. <br />The problems are detailed below, and they are organized in the following <br />categories: bedrock wells; spoil wells; alluvial wells; springs, and surface <br />water sites: <br />Bedrock Wells <br />Well 006-82-74C - <br />Only one full suite water quality sample was collected for the <br />water year 1986-1987. The sample was collected during May 1987. <br />Two such samples are required. The December 1987 sample can be <br />used to replace the missing sample if two additional samples are <br />collected for the current water year. Please verify that this will <br />occur. <br />Well 009-79-4 - <br />The required sampling frequency was met; however, carbonate was not <br />analyzed for the October 1986 and Hay 1987 samples. <br />215 Centennial Building, 1313 Sherman Street Denver, Colorado 80203-2273 Tel.
