Lamm <br />Governor <br />T0: Randy Price <br />FROM: Jim Pendleton <br />RE: "Inspection <br />MEMORANDUM <br />\i4 May 1986 <br />/) _ n <br />1 1986 Landsliding, Bear Mine No. 3" <br />I have reviewed the short inspection report <br />regarding the landsliding which occurred at <br />was prepared by Ken Myers, P.E., consultant <br />prepared most of the engineered designs and <br />within the Bear No. 3 Mine permit documents <br />access road. <br />submitted by Bear Mining Company, <br />the Bear No. 3 Mine. This report <br />to the operator. Mr. Myers has <br />stability analyses contained <br />relating to the portal bench and <br />Mr. Myers observations are compatible with those expressed within my <br />inspection report of May 7, 1986. Mr. Myers quantifies the locations and <br />quantities of materials involved in the slides. He observes that the majority <br />of the landsliding was not caused by mining activity at the site. Landsliding <br />is relatively epidemic within the North Fork Valley this spring. <br />Mr. Myers observes that "design alternatives for dealing with the problem may <br />be developed during the next month and implemented during the relatively dry <br />'window' in late May and June. Mr. Myers briefly discusses several design and <br />treatment alternatives within the report. <br />As I stated in my inspection report, the operator should prepare and submit a <br />plan for resolution of the stability problems no later than May 31, 1986. I <br />realize that ~ choice of wording may be confusing. My intention was to <br />require the operator to submit a schedule for the completion of a remedial <br />design and construction activities by that date. I believe the operator <br />should be able to complete remedial treatments prior to the end this fall's <br />construction season, However, remedial treatment cannot commence until the <br />materials have dried sufficiently to stabilize. <br />cc: Bob Liddle <br />JP/jP <br />423 Centennial Building, 1313 Sherman Street Denver, Colorado 80203 Tel.
