Box 535 Di~i,~n~ DireClor <br />Somerset, Colorado 81434 <br />Re: Technical Revision No. 33, Pond E As-Built, Sanborn Creek Mine, Permit No. C-81-022, <br />Oxbow Mining Inc. <br />Dear Ms. Welt: <br />Enclosed is the Division's reclamation cost estimate for pond E, the emergency discharge pond. <br />The Division's estimate represents an increase in liability of $4,052.00 over the currently <br />approved reclamation liability cost. The Division's estimate is $1,022.00 greater than the <br />estimate submitted by Oxbow Mining, lnc. because of a higher cost of replacing topsoil <br />($1,611.00 versus $800.00) and a greater indirect cost percentage (18.76% versus 12%). <br />Please review the Division's estimate and let us know whether or not you agree with it. <br />If you have any questions, please call me. <br />Sincerely, <br />~.J µ~Ge-~-Q <br />seph.
