Reclamation Plan Pantaleo Pit Page 3 51 The following mix is adapted to the site, will serve the post- mining use and will provide adequate soil protection. These species will tolerate natural conditions and after full establishment, will survive without irrigation.

The drill should 6e equipoed with a satisfactory seeding mechanism, agitator, double disk furrow openers, depth bands, and packer wheels or drag chains. The distance between drill rows should not exceed 12 inches. Seed may be broadcast in areas which are inaccessible for drilling. If the seed is broadcast, then the seeding rates in item 5 should be doubled. The broadcasted seed should be uniformly distributed over the ground surface, and mixed into the soil with a harrow or by hand raking. Planting (broadcast or drill method) can be done anytime between November 1 and April 30. Do not seed when the soil surface is frozen. The seeds should be planted between 1/2 and 1.0 inch deep. 7) Mulch should be applied to the reseeded area to help moderate soil temperatures, and to improve soil moisture absorption and holding capacity. Grass hay or cereal grain straw free of weed seeds is recommended. Apply 4000 pounds of mulch/acre to the soil surface. At least half of the material should be 10 inches or more in length. Do not use fine materials. The mulch should be anchored either with commercial netting products (on slopes steeper than 3:1) or mechanically. The latter can be accomplished using a heavy disk implement, with dull blades, to punch the mulch into the soil 2 to 3 inches deep. Crimping should not sever the mulch. Do not mulch when wind velocities exceed 15 miles per hour. Well- cured feedlot or barnyard manure may also be used as a combination mulch/organic matter and nutrient source for the seeded area. Recommended application rate is at least 20 tons per acre, spread uniformly over the area. The manure must be of a type that has 600 or more, by weight, heavy chunks 5 inches or more in diameter. Granular or powdery manure will not meet specifications. Repeated applications of manure for fertilization effect are not recommended, due to potential salt accumulation.
