PARCEL, MAURO, HULTIN & SPAANSTRA, P.G. <br />Ms. Cathy Begej <br />December 4, 1990 <br />Page 2 <br />At the November 2, 1990 meeting, CMI.RD requested that Rockcastle reevaluate the <br />stability of the remaining ten potentially unstable slope segments identified in the ACZ <br />Report. CMLRD requested this reevaluation to verify that the remaining potentially <br />unstable slope segments were either stable in their current configuration or, if necessary, <br />identify necessary stabilization measures. While Rockcastle does not believe that <br />reevaluation of these additional potential slope failures is contemplated in § N.2 of the <br />CMLRD Agreement, Rockcastle has agreed to reevaluate the remaining ten potentially <br />unstable slopes and submit this information to CMI.RD. <br />Please find the enclosed engineering evaluation prepared by ACZ in response to <br />CMLRD's November 2, 1990 request. As set forth more fully in the evaluation, ACZ <br />inspected the remaining potentially unstable slope segments and proposed reclamation <br />activities where appropriate. Based upon the reevaluation of these remaining potentially <br />unstable slope azeas, ACZ determined that the remaining segments are generally stable in <br />their current configuration. ACZ proposes installation of rock toe drains, similar to the one <br />~~ installed at Segment No. 3, for Segment Nos. 1 and 4 to assure stability of these areas.. <br />Rockcastle is prepazed to complete the remedial measures proposed by ACZ for Segment <br />Nos. 1 and 4 promptly upon receipt of necessary CMLRD approvals. <br />Rockcastle believes that submission of the attached information fully satisfies <br />CMI12D's November 2, 1990 request to reevaluate the remaining potentially unstable slope <br />segments. Further, Rockcastle believes that completion of the remedial measures proposed <br />in the attached engineering evaluation completely satisfy all reclamation obligations set forth <br />in § IV.2 of the CMI12D Agreement. <br />Please contact me if you have any questions regarding the attached engineering <br />evaluation, the proposed reclamation for Segment Nos. 1 and 4, or if you have any other <br />questions regarding this matter. Thank you. <br />Sincerely, <br />PARCEL, MALIRO, HULTIN & SPAANSTRA, P.C. <br />., ~~~, t <br />-ant C~~m~ersbn. <br />ATTORNEYS FOR THE ROCKCASILE COMPANY <br />BCA:bmc <br />Enclosure <br />cc: David J.
