E~~A <br />s CnalCOmpany Seneca Coal Company <br />DECEIVED <br />February 10, 2000 <br />FEB 1_ i 200p <br />Mr. Michael Boulay <br />Division of Minerals and Geology LlivisionofMme~~s8Ge010gy <br />1313 Sherman Street, Room 215 <br />Denver, CO 80203-2273 <br />RE: Permit C-94-082, Yoast 1999 Revegetation Monitoring Report <br />Dear Mr. Boulay: <br />Please find enclosed two copies of the 1999 Revegetation <br />Monitoring Report for the Yoast Mine of Seneca Coal Company. The <br />field work and reporting was conducted by ESCO Associates, inc., <br />with Dr. David Buckner as principal investigator. I am confident <br />your staff will find the monitoring report of the quality <br />exhibited in previous reports for the Seneca II and II-W Mines, <br />since this is the initial report for Yoast. Monitoring at Yoast <br />is oriented towards measuring the status of variously-aged <br />reclaimed units and the success of revegetation procedures. More <br />importantly, monitoring aids in evaluating the affects of <br />successional processes on reclaimed communities. <br />SCC and ESCO welcome any comments you or your staff may have on <br />the information provided in this report. Please contact me or Roy <br />Karo if you or any other members of the Division have any <br />questions concerning the enclosed materials. <br />Respectfully, <br />'C ~.
