Of01 OIIXICO 81103 - <br />60~168b100 ^ ~ ~ ' ~ <br />March 27, 1986 <br />-n <br />Mr. Mike Savage ~~n, ~ J ~ ~158~ ~ , <br />Reclamation Specialist <br />Mined Land Reclamation Division <br />Department of Natural Resources ~ . <br />423 Centennial Building . <br />1313 Sherman Street <br />Denver, Colorado 80203 <br />RE: Carbon Junction Mine - Certification of Placement and Compaction <br />of Fill Paterial for Fill Area - First Quarter of 1986 <br />Dear Mr. Savage: <br />I am a professional Engineer registered in the states of Colorado, <br />New Mexico, and Idaho. My experience in the design and construction <br />of facilities to handle surface and subsurface drainage associated <br />with surface coal mines began in 1972 where I was responsible for <br />such work at a major coal mine complex in Ohio. I continued to <br />be active in this area for a major engineering and construction <br />firm and completed work on projects located in New Mexico, Wyoming, <br />Montana, Texas, and Colorado during the period from 1975 - 1978. <br />Since 1978 I have been responsible for the design and implementation <br />of the mining operations and their support facilities under the <br />New Mexico regulatory program for Sunbelt Mining Company, Inc. <br />Under contract to Pueblo Coal, Inc. I have personally inspected <br />the Fill Area for the disposal of excess spoil at the Carbon Junction <br />Mine on March 11, 1986. The purpose for my inspections were to <br />ensure that construction satisfied the requirements of Rule 4.09.1 <br />(11) of the Colorado Mined Land Reclamation Board. <br />During my inspection I noted the following: <br />1. Subject fill appeared to be stable in all areas with no <br />evidence of slumping, washout, or other movement in the <br />interior or along the flanks of the fill. <br />2. Material in fill is comprised of predominately sandstone <br />materials with a maximum size of 3-4 feet. <br />3. Blasted sandstone From within the pit appears to have <br />been placed in approximately 6-foot lifts using <br />end-dump trucks. The sandstone was then distributed <br />and reduced through compaction by bulldozers. This <br />process resulted in final lift heights of approximately <br />4 feet. <br />4. All material appears to have been placed and compacted <br />in accordance with sound industry operating practices. <br />
