Long <br />Dim stun Dirtt~or <br />Mr. Jim Stover <br />MINREC, Inc. <br />2768 Compass Drive, Suite 101 <br />Grand Junction, CO 81506 <br />RE: Quarterly Hench Stability Monitoring; Blue Ribbon Mine; File <br />No. C-81-047 <br />Dear Mr. Stover: <br />The Division has reviewed the second quarter 1993 bench stability <br />monitoring reports. The survey was performed July 3, 1993. <br />Although, the bench has had two slope failures this spring, the <br />survey results indicate that the bench continues to be structurally <br />stable overall. The surveys show that very little movement has <br />occurred since the monuments were installed in 1985 and since the <br />last survey was performed on March 23, 1993. No Division concerns <br />have resulted from review of this data. <br />The Division is in the process of 'reviewing MINREC's plan to repair <br />the two slope failures. The repair plan will be implemented early <br />this fall. <br />Please let me know if you have any questions. <br />Sincerely, <br />Christine E. ~thston <br />Reclamation S e alist <br />BENMON <br />
