Carbon Valley Resource, M-2001-017 WEED CONTROL PLAN <br /> Management of Noxious Weeds during Mining and Reclamation (continued) <br /> Control Methods Durinq Mininq (continued) <br /> - Slope affected areas to facilitate rapid drying of surface soils <br /> - Convey water via pipes or other means to prevent wetted soils <br /> Control/Management Types <br /> - Mechanical - Root plowing, bulldozing, fire, inundation <br /> - Chemical - Foliage spraying, cut-stump spraying <br /> - Cultural - revegetating affected areas and topsoil stockpiles with approved seed mix <br /> - Animal - grazing <br /> - Farming - farm land that is not being mined (plowing, growing crops) <br /> Control Methods During Reclamation <br /> - Contemporaneous reclamation and quick seeding following topsoil placement <br /> - Proper soil management -will try to use clean soil that is not infested with weed seeds <br /> - Maintain positive drainage <br /> - When possible, apply topsoil in the fall and seed immediately after application (helps to avoid <br /> high weed growth period) <br /> - Spot spray establishing weeds if found during reclamation operations or shortly thereafter <br /> Control Methods Following Reclamation <br /> - Closely monitor all reclaimed 'areas for plant establishment success and weed infestations <br /> - Reseed any areas of non-establishment in the next available season <br /> - Mechanically and chemically control any weed infestations found <br /> Management of Weeds of special interest in Weld County <br /> Cheatgrass Field bindweed <br /> Canada thistle Dalmatian toadflax <br /> These weeds will be controlled, as needed, using the techniques and timing/schedule listed in the <br /> following text. This information was provided by Ms. Tina Booten, Weld County Weed Control agent. <br /> Cheatgrass: <br /> Esplanade® at 5 oz/acre in July/early August as a pre-emergent treatment. Treatments will be <br /> made using both broadcast spray on the large patches and handgun treatments of the small <br /> patches. Esplanade has shown to provide two years worth of control of cheatgrass whose seed <br /> longevity is fairly short. A spring inspection in February/March (as soon as snow load is gone and <br /> the site is accessible) will be conducted to determine if any other treatments are needed before the <br /> native plants become active. <br /> Field bindweed, Canada thistle and Dalmatian toadflax: <br /> Tordon® at 32 oz/acre with an MSO surfactant at 32 oz/100 gallons will be used to treat these <br /> species in September/October. These patches will be treated by handgun work to limit any impact <br /> to surrounding forbs. A spring inspection in May/June will be conducted to see if a spring treatment <br /> is necessary or another fall treatment. <br /> Estimated Cost of Weed Control <br /> $2500 to $5000 per year <br />
