My experience in 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 <br />for such work at a major coal mine complex in Ohio. I continued <br />to 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 <br />Junction Mine on June 20, 1986. The purpose for my inspections <br />were to ensure that construction satisfied the requirements of <br />Rule 4.09.1 (11) of the Colorado Mined Land Reclamation Board. <br />During my inspection I noted the following: <br />1. No new material has been placed in the fill area since <br />my last inspection on March 11, 1986. <br />2. Subject fill appeared to be stable in all areas with <br />no evidence of slumping, washout, or other movement <br />in the interior or along the flanks of the fill. <br />3. Material in £ill is comprised of predominately sandstone <br />materials with a maximum size of 3-4 feet. <br />4. Blasted sandstone from within the pit appears to have <br />been placed in approximately 6-foot lifts using end-dump <br />
