BANTA, Director <br />November 30, 1989 <br />Mr. Ridc Mills <br />Colorado Yampa Coal Company <br />29587 Routt County Road No. 27 <br />Oak Creek, Colorado 80467 <br />RE: Pond H Embankment Survey - C-81-071 <br />Dear Mr. Mills: <br />We have reviewed the information contained in the CYCC letter, dated <br />November 3, 1989, regarding the Pond H embankment survey. The embankment does <br />not appear to be moving substantially; however, extensive cracking was noted <br />throughout the 1989 field season. No additional survey data is required at <br />this time, but we recommend that the survey pins should be left in place to <br />facilitate future observations. <br />Please ensure that the Pond H embankment is closely monitored through the <br />coming year. Be sure that if the cracks reappear, your pond inspector <br />properly records their existence on the quarterly forms. To date, the <br />existence of cracks has not been recorded. Any evidence of instability must <br />be reported to the Division promptly. <br />Thank you for your cooperation in monitoring Pond H. Please call if you have <br />any questions. <br />Sincerely , <br />'%_ <br />~ ~ id;A Berry <br />- R~lamation Specialist <br />DAB/yjb <br />cc: Michael Savage <br />1839E <br />215 Centennial Building, 1313 Sherman Street Denver, Colorado 80203-2273 Tel.
