5 (f) A description of each of the following: (i) Final grading - specify maximum anticipated slope gradient or expected ranges thereof; Final grades in the highwall area will be 0.25:1 with 40' vertical runs and 30' wide benches. Rock faces will be left as rock outcrop with benches graded to toe of vertical face at 5% slope. Final grades within topsoiled main pit area will be kept at 3:1 where possible. Final grades of storm water detention pond area north of mining area will be 3:1 on outslope of sediment ponds. Rip- rapped inlets and spillways from one sediment pond to another in the system may have slopes up to 2:1. (ii) Seeding - specify types, mixtures, quantities, and expected time(s) of seeding and planting; Mixtures will be a minimum of ten species from the list of grasses, shrubs, and tree species on page 2 -3 of this Exhibit, based on price and availability at the time of purchase. The operator will attempt to include at least four species of woody stem plants in each seed mixture. (iii) Fertilization - if applicable, specify types, mixtures, quantities and time of application; It is assumed that a one -time initial application of app. 100 # / acre Nitrogen and 80# /acre Phosphorus will be necessary at the time of first seeding, although these amounts may be adjusted after soil analysis is performed prior to seeding of the site. It is not assumed that subsequent inorganic fertilizer applications will be necessary unless called for by future soil analysis or lack of vegetative success. (iv) Revegetation - specify types of trees, shrubs, etc., quantities, size and location; and No plantings of tree or shrub seedlings are planned for at this site. Seeding of woody plant species including tree species will be included with overall seed mixture. Emerging woody plant species may need maintenance such as removal of competing grasses in the area directly adjacent to the woody plant and mulch application around young woody plants to promote moisture retention and plant growth. (v) Topsoiling - specify anticipated minimum depth or range of depths for those areas where topsoil will be replaced. Plans for topsoiling will include the final pit floor configuration at a depth of between 12 " -18 ". Topsoiling will be performed beginning no earlier than 2050 or when final pit elevation is reached in area not being utilized for stockpiling or loading of finished product. configuration 2057-2077 Final pit floor elevation attained 2077-2082 Main pit area topsoil /plant medium Pit floor revegetation hauled to main pit area, revegetation initiated at southern end of main pit area begins of lower pit, then moving northward (f) A description of each of the following: (i) Final grading - specify maximum anticipated slope gradient or expected ranges thereof; Final grades in the highwall area will be 0.25:1 with 40' vertical runs and 30' wide benches.
