STREET PENROSE, COLORADO 81240 pp CC ~ ! 719-372-6461 <br />CERTIFICATION <br />APR081991 <br />Tvlined i_and <br />Reclamation Division <br />I, Lawrence G. White, a Registered Engineer in the state of Colorado, <br />Registration NO. 7964, do hereby certify that I have inspected the <br />North Spoil Area at Twin Pines No. 2 Mine for stability and compliance <br />with Section 2.05.10, "Underground Development Waste" of the permit <br />application. The Spoil Pile was inspected March 25, 1991 with a repre- <br />sentative from Lincoln Devore Inc. on site to check compaction and the <br />construction of the pile. The Lincoln Devore report is enclosed. As <br />shown in the report the level of the pile is approximately 7 feet <br />above the level of the toe dike. Based on the site inspection and <br />the results of compaction tests on the fill, I find the placement <br />of fill at the site to be in-accordance with the permit application <br />and the "Rules and Regulations" of the Colorado Mined Land Reclamation <br />Division. <br />i ' <br />awrence G. ite P.E. <br />Colorado Registration No. 7964 <br />April 4, 1991 <br />
