Dudash,Joe <br />From: Walker, Byron <br />Sent: Thursday, May 29, 2003 11:03 AM <br />To: Dudash,Joe <br />Cc: Brown, Sandy; Hernandez, Dan <br />Subject: Bruce Park Dam, GEI letter of May 22, 2003 <br />Joe, I have reviewed the GEI Consultants, Inc. letter of May 22, 2003, Re: Additional Analysis: Geotechnical Evaluation of <br />Mine-Induced Seismicity on Bruce Park Dam. The information in this letter satisfies my concern as described in my <br />telephone contact report of 11 December 2002, with Bob Huzjak of GEI Consultants, Inc. This letter should be made a part <br />of the Permit Application Package, especially Attachment C, the Figure 3.4 annotated as modified. This represents that the <br />anticipated yield acceleration (average maximum acceleration line) is below the yield acceleration of failure with a safety of <br />factor of 1.2. Please see me if you have any questions. The letter has been given to Alysha, with instructions to return to <br />Sandy. Byron <br />
