• nitrogen, and phosphorus. If the results of these tests indicate a fertilizer or other soil amendment is <br />needed, and if the species being planted will not compensate for the soil limitations (e.g., legumes replenish <br />nitrogen), then appropriate soil amendments will be added. <br />As seen in the Topsoil Management Plan and Scheduling section (Tab 9, Attachment 1), topsoil to be <br />redistributed will come from stockpiles or will be transferred directly to graded areas from in-place topsoil <br />which is ahead of mining. Direct hauling of topsoil will be done as much as possible, When a topsoil <br />stockpile is placed, it will not be moved until materials are needed for distribution on graded areas. After a <br />stockpile is distributed and the area is no longer needed for stockpiling, a cover crop and/or the permanent <br />seed mix will be seeded in the first planting season after stodkpile removal. <br />Seneca does not propose to use any selected overburden materials as topsoil substitutes. This is based <br />upon topsoil balance figures for the life-0f-mine operation contained in Tab 9, Attachments 9-4, 9-5, 9-7, and <br />9-8 which show a mean thickness of approximately 12 inches of topsoil will be available for replacement. <br />Soil replacement thickness after 1993 will typically range between 9 and 15 inches. Curent literature and <br />on-site data show that 6 to 15 inches of topsoil underlain with chemically and physicalty suitable spoil <br />material will be sufficent to 1) establish a proper seedbed and rooting medium and 2) achieve a compatible <br />relationship between production, diversity, and plant community composition. If topsoil substitutes are <br />required by the regulatory authorities, the matedal to be used as a topsoil substitute wiN be removed, <br />segregated, and replaced in conformance with Rule 4.06 of CMLRB Rules and Regulations. Stockpiling of <br />topsoil substitute materials would contorm with the topsoil stockpiling methods and procedures of this permit. <br />A topsoil resource quality control program will remain in effect over this five-year permit term to 1) ensure <br />topsoil is salvaged and replaced as recommended, 2) evaluate topsoil and spoil handling procedures, and 3) <br />monitor long-term revegetation success. An annual soil balance wilt be completed through the fife-of-mine <br />operation. <br />Revedetation <br />The following sections detail seedbed preparation, seed mixes, plant lists, and seeding and planting <br />methods. Measures to enhance natural regeneration of native species or establish native species from seed <br />and seedlings, have been emphasized. Implementation of these revegetafion plan components, in <br />association with other reclamation procedures such as backfilling and grading and topsoil management, will <br />ensure a rapid return of surface stability, accelerate natural succession and plant community development, <br />• and achieve postmine land use goals. <br />TR-37 139 Revised 04!05 <br />
