nitrogen must be limited in the soil. Their recommendation for establishing native plants from shrubs to grasses to grasses to foxbs is to forgo the application of supplemental nitrogen, and in cases where weed axe a major or potential problem, tie-up the available soIl nitrogen with an available carbon source such as sugar. OMLLC, therefore, does not propose any addition of supplemental nitrogen. Soil fertility analysis may call for the addition of supplemental phosphorus. If supplemental phosphorus is called for OMLLC will apply 50 to 75 Ibs per acre of phosphorus fertilizer (PZO~) to be incorporated to a depth of 1-3 inches by mechanical means. This incorporation of the phosphate in the upper 3 inches of the plant growth medium will assist with the establishment and the growth of the germinating species during the critical early seedling development phases. There may be site-specific conditions (steep slope areas fox example) where the application of phosphorus may not be practical ox possible for safety, rocky or other site-specific reasons. 2.7 CONTROL OF WEEDS This weed control plan is concerned with the control of a wide variety of noxious weeds, thistles, etc. located on mine disturbance areas. The Delta County Noxious Weed website and personnel have been consulted regarding a Noxious Weed Program. Disturbed aeeas, topsoil stockpiles and reclaimed/seeded areas could be invaded by the following noxious weed species with control afforded by the described techniques. Musk, Scotch Thistles, Burdock, Houndstongue, Tamarisk, Puncturevine - Controlled by Banvel/2,4-D mixture, Curtail or Redeem Herbicides and non-ionic surfactant applied in spring or early summer. Canada Thistle, Russian, Diffuse and Spotted Knapweeds, Yellow Toadflax and Oxeye Daisy, Bindweed -Controlled by Curtail or Redeem ox Totdon hjerbicides and surfactant applied in Spring or Fall. White Top -controlled by Escort or Telar herbicides with surfactant in the spring Leafy spurge -Controlled by Tordon in spring or early summer. The herbicides and surfactant will be apphed in accordance with the individual label requirements using a hand held or backpack ox pickup/ATV mounted sprayer. Contractors and/or OMLLC employees may apply the herbicides. Care will be taken to avoid drift onto desirable species and to avoid windy conditions. OMLLC will maintain records of herbicide use on the property for inspection by Division personnel. The weed control records will document the location where weed control was performed, the type of weed control employed, and the date when the weed control was performed. As part of its Annual Reclamation Report (ARR) required under Rule 2.04.13, OMLLC will summarize its weed control activities for the year. Other mechanical or biological means of weed control such as discing, shoveling and insects may also be employed to control weeds on disturbed areas MR-83 H-7 Revised Feb 2006
