Interoffice Memorandum <br />To: Rob Zuber <br />From: Zach Trujillo <br />Subject: Colowyo — Review of South Taylor Fill Report <br />Date: 4/05/2012 <br />••• <br />After my review of the South Taylor's First Quarter Fill Monitoring Report for the year 2012, 1 find the report in <br />compliance with the following rules: <br />1. 4.09.1(11)(a) —The fill was inspected for stability by a registered engineer during the placement and compaction <br />of fill materials. <br />2. 4.09(11)(b) —The qualified registered engineer provided to the Division a certified report within two weeks after <br />the inspection that the fill is being constructed as specified in the design approved by the Division. The South <br />Taylor Fill was inspected on March 13, 2012 and the Quarterly Fill Monitoring Report was received by the <br />Division on March 19, 2012. No appearances of instability, structural weakness, and other hazardous conditions <br />were noted in the inspection report. <br />3. 4.09(11)(c) — Rule 4.09(11)(c) is no longer applicable during this stage of fill construction. Colored photographs <br />of the South Taylor's Underdrain Areas were attached in the 2008 Third Quarter Fill Monitoring Report. <br />The 2012 First Quarter South Taylor Fill report for Colowyo Mine meets all rules required by the Division. If you have any <br />questions, feel free to contact me. <br />Thanks, <br />Zach <br />
