Walther <br />Executive Director <br />Ronald W. Cattany <br />Acting Division Director <br />The Division has reviewed Seneca Coal Company's (BCC's) 2001 Annual Hydrology Report (AHR) <br />for the Yoast Mine. The frequency of data collection is incompliance with the approved monitoring <br />plan contained in the pemut document. The 2001 AHR was well organized and SCC did a good job <br />at collecting and reporting the required monitoring data. <br />Samples for water quality analysis could not be obtained at several monitoring locations due to low <br />flow or dry conditions. Wells YWCU31 and YOV29 were dry at all three attempts to obtain water <br />level information throughout Water Yeaz 2001 and samples for laboratory analysis could not be <br />obtained from either of these wells. Water quality samples were not obtained for springs YSPG6 <br />and YSPG10 due to low flow conditions (less than 5 gallons per minute). Only field parameters <br />were collected at these spring locations. At surface water location YSSF3, the flow was to low to <br />complete the triannual sampling and field measurements could not be obtained beyond July at this <br />surface water site. <br />The Division has no further comments regazding the 2001 AHR and the report is acceptable as <br />submitted. No further response is required- <br />If you have any questions concerning the Division's review of the 2001AHR, please contact me. <br />Sincerely, <br />M ir~acQ ~? <br />Michael P.
