for the tie-across haul road, and 32.8 acres where soil was replaced during 7990 through <br />1993. Wo soil was salvaged or needs to be replaced beneath the soil stockpile sites. <br />Also, since the mine entrance road, Pond 005, Pond 006, Haul Road A, and Haul Road G are <br />permanent postmine facilities, soil will not be replaced on 66.5 acres. The disturbance <br />area requiring sail replacement as of December 31, 7993 totals 394.7 acres at the mine <br />site and 96.6 acres for the tie-across haul road (see Table 93.2). <br />There ere 574.8 acres of lend at the mine that is or will be disturbed by mining which <br />will receive replaced soil during the first permit term. As of December 31, 1993, there <br />were 594.7 acre-feet of stockpiled soil and 226.7 acre-feet of soil remaining to be <br />salvaged. This soil (820.8 acre-feet) will be used to cover the 574.8 acre disturbance <br />area with 1.3 feet of suitable soil. The average thickness of repl ec ed soil is likely to <br />exceed 1.3 feet es the stockpiled soil swells during redistribution (BSC C, 7993). The <br />average thickness of replaced soil in the tie-across haul road corridor wilt be 0.7 feet <br />(69.7 acre-feet/96.6 acres). <br />Summary. The soil replacement thickness for the first five-year permit term was <br />projected to be 1.3 feet (PAP C-82-057, Tab 21, Ninesoil Reconstruction). The balance <br />completed above shows 1.3 feet of soil will be available to 6e replaced. Peabody uitl <br />continue to salvage, store, and replace soil es described and approved in PAP C-82-057. <br />Peabody's soil scientist and reclamation supervisor will continue to closely monitor soil <br />salvage activities at Seneca II-4 Mine verifying that scraper operators are salvaging all <br />suitable soil materials end repl sting soil at the specified thickness. <br />Reveaetation <br />Seeding and Plantino. A total of 16.6 acres were permanently seeded in the south mine <br />block of the Seneca II-W Mine in 7993. Seedings included 15.0 acres seeded with Seed Mix <br />No. 1 - Upland Sites and Ephemeral Drainages and supplemented with additional forb and <br />shrub seed, end 1.6 acres seeded with a mix comprised of shrub species only. The two <br />seed mixes end seeding rates ere listed in Table 93.3. There were no permanent <br />revegetation activities in the north mine block. Seeded areas are shown on Exhibit 93.3, <br />"1993 Seeding, Planting, and Weed Control Locations". Seedbed preparation in the seeded <br />areas was restricted due to replacement of live-handled topsoil, However, replaced <br />subsoil was disted to break up clods and allow better distribution of replaced <br />live-handled topsoil. Seeding was completed with a modified rangeland type drill seeder <br />equipped with two seed boxes (one for small seed and one for large seed) and depth bands <br />on the disc openers. The seed mixes were split into small and large seed components for <br />8 <br />
