Method ojseeding <br /> Seeding will take place once final grading and replacement of topsoil have been completed. The <br /> timing of seeding will be consistent with standard horticultural practice for dryland applications— <br /> generally between late September and the middle of April to assure adequate moisture for <br /> germination. Additional plantings will be installed once the ponds have filled with water and will be <br /> watered by hand for the first two growing seasons. <br /> Mulch will be applied to seeded areas. All newly seeded areas shall receive a uniform layer of <br /> mulch applied at the rate of 2 tons per acre, crimped with a crimper or other approved methods. <br /> Material for mulching shall consist of hay or straw, oats. wheat, barley, or rye, and shall be free of <br /> noxious weed seeds. At least 50% of the mulch by weight shall be uniform in length. <br /> Seed shall meet Colorado Department of Agriculture Seed Laws, Chapter 35, Article 27. The <br /> seeding mixture shall be applied at a pure live seed (PLS) rate per acre per the drawings. The <br /> formula for determining the quantity of pure live seed (PLS) shall be: <br /> Pounds of Seed (Bulk) x Purity x Germination = Pounds of Pure Live Seed (PLS). <br /> All grass seed furnished shall be delivered in sealed bags showing weight, analysis and vendor's <br /> name. If the seed is broadcast, the seeding rates will be doubled. <br /> Weed Management Plan <br /> Hall-Irwin Corporation has a full-time weed manager on staff. This person is responsible for <br /> monitoring and controlling noxious weeds as they appear. Hall-Irwin typically prefers to control <br /> weeds mechanically, by mowing and/or discing. If necessary, weeds will be killed with a contact <br /> herbicide. Hall-Irwin employs two people who are certified to purchase and handle the <br /> herbicides. In addition, they have all of the necessary equipment in-house to perform these tasks. <br /> Reclamation Schedule <br /> Reclamation will proceed concurrently with the mining. Grading and replacement of topsoil will be <br /> completed once the material adjacent to the pond bank has been sufficiently removed to allow <br /> shaping of the bank-. Mining proceeds from the outside toward the center of the pond, therefore the <br /> perimeter of the area will be regraded and reseeded before all material has been removed from each <br /> phase. The regraded banks will be seeded at the earliest appropriate time to ensure there is adequate <br /> moisture for germination. <br /> The reclamation sequence will include regrading, replacement of about 12" of topsoil and seeding <br /> during the appropriate season to assure adequate moisture for germination and weed control to <br /> assure that grasses can establish. Additional plantings will be installed once the ponds are full of <br /> water. <br /> NORTH LA POUDRE RESOURCE Page-17- <br />
