and stock tanks. Twenty-one stock ponds were constructed throughout the life of mining <br />in the reclaim areas. Seneca Coal Company has retained thirteen of the stock ponds as <br />permanent features. These thirteen stock ponds meet the design criteria of 4.05.9 for <br />permanent impoundments. The impoundments will serve as a water supply for livestock <br />and wildlife in the area. Details of the construction and location of these impoundments <br />are located in Attachment 7-2 and Appendix 13-9 of the PAP. (4.14.2(3)). <br />4. The Division approved the applicant's plan for disposal of debris, acid-forming or toxic <br />materials, or materials constituting a fire hazard in a manner designed to prevent <br />contamination of ground or surface waters. A contingency plan has been developed to <br />prevent sustained combustion of flammable materials. Details of the mitigation plan for <br />acid-forming spoils encountered in the Wolf Creek mining, area are located in Tab 6 of <br />the permit application package. (4.14.3(1)(a)). <br />Spoil materials with pH values of less than 5 and an acid base potential (ABP) of less <br />than -5 were covered with two to three feet of suitable spoil ]material, or were treated with <br />application of lime. <br />Materials found to contain high concentrations of sodium were disposed of in mining pits <br />or were covered with two to three feet of suitable spoil. <br />All exposed coal seams remaining after mining were covered with a minimum of four <br />feet of the best available material. <br />5. The Division previously approved the method and design specifications for covering of <br />acid and toxic-forming materials in order to prevent leaching into surface and ground <br />water and to insure backfill stability. (4.14.3(2)). <br />IX. Revegetation <br />Information regarding revegetation practices and success criteria can be found in Section <br />2.05.4(2) and Exhibit 2.04.10-E1 of the permit application. SCCC collected baseline <br />vegetation data in 2008. Baseline sampling was performed in accordance with the <br />Regulations and was discussed with the Division prior to data collection. The data are <br />supplemented by data from the Seneca II and Yoast Mine permit applications, collected since <br />1987. <br />Seedbed preparation will include disking and/or contour ripping. Ripping will provide a <br />rough surface for holding the seed, promoting moisture retention and root penetration, and <br />for minimizing runoff until vegetation becomes established. Mulching, fertilizing, or <br />irrigation are not proposed. Disturbed areas will be seeded using drill, broadcast, and/or <br />hydromulch methods, depending on slope gradient. <br />Exhibit 2.04.13-E1 lists seed mixes that have been used for revegetation seeding throughout <br />the life of reclamation on the lands that will be transferred from the Seneca II Mine permit <br />area to the PSCM permit area.
