UTILITY AND CONSTRUCTION SURVEYS <br />Harry Ranney <br />Colorado Division of Minerals & Geology <br />1313 Sherman Street, Room 215 <br />Denver, CO 80203 <br />RE: CARBON JUNCTION MINE; NO. C-92-080; ANNUAL REPORT <br />Deaz Mr. Ranney: <br />This is to confine that I have conducted periodic examinations of the subject mine facilities during the <br />year 1996. In addition, Lambert & Associates, geotechnical engineers, subcontracted to check densities and <br />slopes on the fill pile, and were on site on March 18, May 15 and December 16, 1996. Gravel operations on the <br />neazby gravel pit were somewhat curtailed during late 1996 due to winter and snow conditions. <br />During my examinations I found the following items to be in reasonable compliance with the applicable <br />sections ofthe mining permit, except as otherwise noted: <br />1. The haul road within the permit boundary. <br />2. Topsoil storage. <br />3. Collection ditches. <br />4. Diversion ditches: During September, 1996, a preliminary design for a diversion structure and <br />ditch interconnect north and east of the fill pile was submitted for your review. <br />5. Sediment ponds Nos. 1 and 2. <br />6. Highwall slopes: On August 19, 1996 a report from Lambert and Associates, relating to the <br />highwall reclamation fill for the north pit, was submitted to the operator for review and <br />submittal onto you. <br />7. Fill storage: Since activity has continued on the gravel operation permit (Ewing Mesa Pit #l, <br />Permit No. M-92-116), overbtudent and waste material has been transported (since <br />approximately June, 1995) to and placed on the fill storage site designated for the subject <br />permit. Attached aze field densities covering placement and compaction of the fill storage <br />pile. <br />Thank you for your continued assistance in the review of the permit requirements. <br />cc: 1) Jim Hendricks <br />2) Mike Savage <br />YNUY hI <br />V t ly your ~ ~ .i~,~ <br />• T•~ <br />ll L ~~ _ <br />u• <br />:~ <br />s •~, ~ 2 <br />•.. ?• Y <br />Harry L.
