RULE 2 PERMITS <br /> The sequence and timetable for all topsoil redistribution and revegetation activities is found on the <br /> Topsoil Handling Map (Map 28 and 28A). This drawing also shows the location of the topsoil <br /> stripping activities for the current term and future terms. <br /> A life-of-mine topsoil balance is estimated in Table 2.05-1. <br /> The time period during the year when topsoil removal, distribution and revegetation operations <br /> take place depends solely on the weather. Generally, topsoil removal and distribution operations <br /> will begin in the spring when soil conditions allow the movement of topsoil, and may continue <br /> until late fall until weather conditions prohibit any further topsoil handling. Revegetation, <br /> typically,will take place during the early spring or fall. <br /> Topsoil in excess of the demands of the direct haul operation to regraded spoil is placed in topsoil <br /> storage stockpiles. The topsoil storage stockpiles for the mine plan area are shown on the Topsoil <br /> Handling Maps 28 and 28A. As can be seen,topsoil stockpiles have been constructed in the permit <br /> area to handle material which is in excess of current redistribution needs. The excess topsoil has <br /> been removed from the mining areas, from haul roads and from mine facility locations. The <br /> planned contemporaneous stockpiling and reapplication will eliminate the need to move topsoil <br /> stockpiles from one area to another prior to reapplication onto graded spoil. <br /> Stockpiles are specifically located to avoid erosion from wind and water and additional compaction <br /> or contamination. As can be determined from the Topsoil Handling Map (Map 28), all stockpiles <br /> are located within stable areas. The piles will be protected from wind erosion by planting a <br /> perennial mixture as explained in Section 4.06.3 as soon as conditions allow. Proper seasons of <br /> planting will be early spring or late fall. In addition to the planted material, a considerable amount <br /> of volunteer growth can be expected to grow on all stockpiled topsoil. <br /> External erosion will be controlled through proper location of the stockpiles.No permanent topsoil <br /> stockpiles will be placed in a drainage bottom where external erosion might pose a potential threat. <br /> Unnecessary compaction will be avoided by keeping all but essential traffic off the stockpiled <br /> areas. Topsoil signs will identify topsoil stockpiles. Contamination of the stockpiles will be <br /> eliminated by the careful selection of sites that are distant from the areas where actual mining <br /> activities are occurring. Drainage ways and areas near spoiling and blasting will be avoided where <br /> possible. <br /> Overburden and Coal <br /> The complete description of the removal, handling and storage of all overburden material within <br /> the permit area is described under the Production, Methods and Equipment Section found at the <br /> beginning of Section 2.05.3. The mining sequence for the planned operation is shown on the Mine <br /> Plan Map (Map 23A and 23B). Cross sections showing the mining operation during the "steady- <br /> state" operation are found on the Mining Range Diagram Map 24B and 24C. <br /> The planned coal production at the Colowyo operation is shown in Table 2.05-2. <br /> Rule 2 Permits 2.05-11 Revision Date: 12/20/19 <br /> Revision No.: TR-135 <br />
