<br />2007 Annual Reclamation Report
<br />Dear Mr. Watterson:
<br />The Division has received the BTU Empire Corporation's (BTUEC) submittal of the
<br />2007 Annual Hydrology Report for the Eagle Mine Complex. Thank you for your timely
<br />submittal of this report. The Eagle Mine Complex is in Temporary Cessation. While no
<br />mining occurred at the site during the 2007 reporting year, the operator did perform the
<br />required water monitoring and continued the pumping of water from the mine's
<br />workings. The following is a brief summary of the report.
<br />BTUEC is required to monitor 11 bedrock wells. These wells are the No. 5 Mine Well,
<br />the Okie Plaza Well, TR-4, TR-7A, 81-01, 83-01, 83-02, 83-03, 259, 84-01 and No. 9
<br />Mine Well. The Okie Plaza Well was, however, abandoned in June 1994 and is no
<br />longer reported. All of the wells are monitored quarterly for water level. The No. 5 Mine
<br />Well, TR-4, TR-7A, 81-01, 259 and the No. 9 Mine Well are monitored quarterly for
<br />field parameters (temp, conductivity, pH, TSS, flow and depth) and annually for full
<br />water quality parameters (T-Alk, Ca, Mg, Na, HC03, C03, As, Cd, Pb, Hg, Se, Zn, Fe,
<br />Mn, B, Mo and N03). The wells were monitored in February, April, August and
<br />November, with the full water quality parameters completed in April. All of the required
<br />monitoring was performed in the 2007 reporting year. All of the samples met applicable
<br />water quality standards.
<br />BTUEC is required to monitor three alluvial wells. These wells are AVF-3, AVF-5 and
<br />AVF-6. All three wells are monitored quarterly for water level, field parameters and full
<br />water quality parameters (as listed above for the bedrock wells). The wells were
<br />monitored in February, April, August and November. All of the required monitoring was
<br />performed in the 2007 reporting year. All of the samples met applicable water quality
<br />standards.
