SECTION 2.05 OPERATION AND RECLAMATION PLAN <br />2.05.1 Objectives <br />Oakridge's objective for the current Section 2.05 is to relate the historical plan of <br />operations and the reclamation plan as executed in 2006 for the mining area and <br />completed in 2009 with the revegetation of the sediment control system. <br />2.05.2 Operation Plan - Estimated Area for the Life of the Operations <br />At this time no further coal mining will occur at the Carbon Junction Mine. The mine has <br />been reclaimed. <br />2.05.2(1) Production Methods and Equipment <br />The Carbon Junction Mine was planned as a steeply dipping seam open pit mining <br />operation, extracting one thick coal seam above a competent sandstone base. Trucks, <br />shovels, and a backhoe were used to conduct overburden extraction and coal removal. <br />No further coal mining will occur at the Carbon Junction Mine under this permit. The <br />mine has been reclaimed. Remaining activities will be limited to those necessary to <br />monitor reclamation. <br />2.05.2(2) Operation Description <br />Activities at the Carbon Junction Mine are solely related to reclamation and monitoring. <br />The mine plan map revised in 2002 shows two foot contour intervals derived from aerial <br />photography in the 1 st quarter of 2002. The base topographic map was developed by La <br />Plata County. The breakdown of reclaimed and retained features (highlighted in yellow) <br />contributing to disturbed acreage at the Carbon Junction Mine is as follows: <br />Area Description <br />Acreage <br />North Pit <br />7.67 <br />North Pit Haul Road (1.10 acres retained) <br />5.89 <br />South Pit Drill Pad <br />1.08 <br />Well B 10 Road <br />0.17 <br />Permanently Reclaimed Spoils Area <br />12.51 <br />Topsoil Stockpile #2 <br />2.69 <br />Topsoil Stockpile #4 <br />3.43 <br />Topsoil Stockpile #7 <br />5.43 <br />Topsoil Stockpile #8, Sediment Pond #1, Equipment Area <br />13.81 <br />Sediment Pond #2 <br />2.51 <br />Main Access road into Site <br />2.75 <br />Carbon Junction Channel (lower, middle, u er) <br />4.06 <br />Total Disturbed Area <br />62.00 <br />Undisturbed Area <br />102.34 <br />Total Coal Permit Area <br />164.34 <br />Abridged Permit Document 5-1 Permit Revision PROI 9/2014 <br />
