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