SUITABLE FOR SUSTAINING VEGETATION THAN AVAILABLE TOPSOIL OR OTHER PLANT GROWTH MEDIA. SUCH DEMONSTRATION SHALL BE BASED ON A REPRESENTATIVE COMPOSITE SAMPLE OF THE MATERIAL OBTAINED FROM EACH POND CLEANOUT EPISODE. REQUIRED PARAMETERS WILL INCLUDE THOSE LISTED IN 4.06.2(4)(a), WITH THE EXCEPTION OF THICKNESS, DEPTH, COARSE FRAGMENTS, AND AREAL EXTENT. ANALYSES FOR SELENIUM, BORON, NITROGEN AND ORGANIC MATTER WILL BE INCLUDED IN ADDITION TO THOSE LISTED. POND CLEANOUT MATERIAL WILL NOT BE PLACED IN THE TOPSOIL STOCKPILE OR USED AS FINAL RECLAMATION TOPDRESSING PRIOR TO OBTAINING WRITTEN APPROVAL FROM THE DIVISION. Surface soils will be sampled and analyzed for fertility levels upon completion of final grading and topdressing. If soil is found to be phosphorus deficient, phosphorus fertilizer will be incorporated into the soil prior to seeding. Other elements if deficient will be added to the soil the following year. The following specific finding is required by Rule 4. The Division has determined selected overburden materials shall be used for, or as a supplement to topsoil. The resulting soil is equal to or better than the available topsoil. This determination is based on physical and chemical analyses approved by the Division (4.06.2(4)(a)). This finding applies to overburden material on the mine bench and haul road outslopes where no topsoil was salvaged prior to disturbance, and also applies to sediment pond cleanout material, subject to the demonstration specified in Stipulation No. 27. IV. SEALING OF DRILLED HOLES AND UNDERGROUND OPENINGS The Division will require that each hole, well or other underground opening be capped, sealed, backfilled, or otherwise properly managed, in accordance with Rule 4.07.3. The application includes portal seal designs (Figures 3.7-1 and 3.7-2) which depict a keyed in concrete block seal a minimum of 25 feet in from the portal opening, which would be backfilled with incombustible material. This design meets the applicable MSHA requirements at 30 CFR 75.1711. V. COAL MINE WASTE Coal mine waste in the form of coal fines scraped up from the coal yard area, high ash coal that cannot be blended and shipped, and coaly sediment from the cleanout of ditches, sediment traps and the sediment pond will be disposed of in an approved permanent coal mine waste disposal site in the adjacent Munger Canyon permit area (Permit No. C-81- 020). The Munger Canyon Mine is also operated by CAM. Detailed construction and reclamation designs for the coal waste disposal site were approved by the Division pursuant to Technical Revision 14 (TR-14) to the Munger Canyon Mine permit, in November 2002. Specific findings pursuant to Rule 4.10.1(2), allowing for disposal of waste material from sources outside of the permit area are included in the approved permit for the Munger Canyon Mine. Development work was completed in the fall of 2004 and 23
