The approved revegetation plan emphasizes native species planting resulting in a diverse, <br />permanent, effective plant community capable of self -regeneration. The current seed mix is <br />included in Section 2.05.4 of the PAP (page 115). <br />Manure or organic mulch is to be spread on the topsand. The approved seed mix will be drill <br />seeded through the organic mulch. Small areas that require reseeding may be broadcast. Two <br />seeding windows exist: <br />1. March 15 to June 1 (spring) and <br />2. September 15 to December 15 (fall). <br />A stubble mulch (such as sorghum) may be applied in the spring or fall prior to seeding of the <br />permanent seed mix. Hay/straw mulch, hydromulch and tackifier, soil amendments, and <br />compost products may also be used. No irrigation is proposed. <br />The site is currently inspected at least quarterly for pests and diseases. No infestations of pests or <br />noxious weed species have been identified. <br />Grazing is prohibited during the first two years of vegetation establishment on reclaimed areas. <br />Grazing may be allowed thereafter. Grazing will not be allowed to interfere with vegetation <br />sampling for monitoring or bond release purposes, and eligible areas will not be grazed during <br />the growing season prior to sampling. <br />Revegetated areas that have experienced three or more growing seasons are monitored for <br />success standards of cover and production. Eligible areas are sampled in the last two consecutive <br />growing seasons prior to final bond release, but not earlier than years nine and ten of the <br />extended liability period. <br />3.3.3 Mining Techniques, Directions, Mine Life, Production Rates <br />No further extraction of coal is anticipated at the site. The estimated mine life is through year <br />2020. <br />3.3.4 Surface Handling of Coal (crush, screen, wash) <br />There is no surface handling of coal at the site, and none is anticipated. <br />3.3.5 Disposal of Waste <br />There are no coal processing wastes or mine development wastes on site, nor will any be <br />generated by current or anticipated future activities. There were, and will be, some reclamation <br />wastes (Non -Coal Wastes) generated by demolition of facilities. These wastes were and may be <br />placed in the pits between the limits of five feet above the local ground water table and four feet <br />below Approximate Original Contour (AOC). Ash (generated off-site at the Trigen power plant <br />in Golden) and mine waste rock is permitted for placement in Pits A (completed) and B. This <br />waste is placed five feet above the re-established local ground water table, and covered with six <br />feet of overburden spoil and two feet of topsand. <br />
