In this report Yampa Valley Coal <br />Corporation (YVCC) has compared the constituents of the March 12, 1987 <br />approved hydrology plan and the previously approved plan. YVCC is informing <br />the CMLRD of the following differences between the two plans. <br />Sites 8/2005, 1002, 1003, 7 and 109 did not have carbonate or free <br />ammonia analyzed since they were not part of the approved hydrology plan <br />until March 12, 1987. <br />Site 16 was a short analysis list except in April and October when full <br />suite analysis occurred. For specific constituents see the 1985 Annual <br />Hydrologic Report for Mine 1, 2 and Eckman Park dated January 30, 1986. <br />All alluvial and bedrock wells did not have carbonate, dissolved lead <br />and dissolved molybdenum analyzed since they were not part of the approved <br />hydrology plan until March 12, 1987. <br />YVCC has also included in this report previously monitored sites which <br />have been deleted from the hydrology plan as described in TR-87-3 approved <br />March 12, 1987. <br />If there are any questions or concerns, please feel free to contact Jim <br />Nalven or myself. <br />Sincerely, ~. <br />~!~y~~~ti~TaZ <br />Richard Mills <br />Senior Environmental Engineer <br />RAM/de <br />Attachment <br />°- <br />
