planting will be done after snowmelt and when soils have sufficiently dried out to allow • <br />equipment to operate without bogging or destroying soil physical conditions. Spring seeding <br />will be completed by June 1. In late winter years, seeding may be delayed until fall. Fall <br />seeding will be conducted from September until approximately November 15. <br />Seeding will be accomplished by drill seeding, broadcast seeding, or in special <br />circumstances, hydroseeding. Drill seeding is the preferred seeding method. A rangeland <br />type drill equipped with several seed boxes for seeding large /small or trashy /smooth seeds <br />will be used for all drill seeding. A hand broadcaster will be used on steep slopes or <br />areas too small for drill seeding operations. Hydroseeding will be considered as an <br />optional method for steep slope reclamation. The seeding rate in both broadcast and <br />hydroseed applications will be approximately double the drill seeding rate. Hydroseeding <br />will be followed by application of 2000 pounds per acre of virgin fibre hydromulch and 100 <br />pounds per acre of an organic tacking agent. <br />Surface Stabilization. The planting of a cover crop of barley or winter wheat will be the <br />principle means of surface stabilization during establishment of perennial vegetative cover. <br />The seeding rate will be approximately 20 pounds per acre. Straw mulching is not being <br />considered for the following reasons. Past experience has shown that regionally available <br />straw is a considerable source of weedy species, particularly noxious weeds such as Canada <br />thistle (Cirsium arvense). The cover crop and seed mixes are capable of establishing an <br />effective vegetative cover during the first growing season. <br />Reseedinq of Previously Seeded Areas. All seeded areas will be monitored for success of <br />perennial vegetation establishment. Soil Conservation Service (SCS) technical guides <br />recommend that a minimum of two years should be allowed to pass before declaring a stand a <br />failure. If monitoring finds low vegetative cover and poor perennial plant density in the <br />second growing season, the area will be reseeded using the appropriate seed mix. <br />Weed and Pest Control. A number of noxious weeds commonly occur in the region surrounding <br />the permit area. Each spring, qualified HGTI personnel will survey and map, as accurately <br />as possible, noxious weed infestations within the mine permit boundary. The management of <br />any identified infestations will vary according to the level of infestation and sensitivity <br />of the surrounding vegetation. HGTI will implement an integrated management approach to <br />weed control - management includes prevention, chemical, mechanical and biological control. . <br />TR -07 6 Revised 03/06 <br />
