• On drilled sites the hay or straw will be crimped with a serrated disc or other appropriate equipment. On steeper slopes and areas where crimping is not feasible, straw or hay will be anchored down using a tackifier, netting, or a tackifier mixed with wood or wood/paper fiber. The tackifier will be applied in accordance with manufacturer's specifications with consideration of the type and quantity of mulch applied, slope, soil conditions and other applicable factors. (v) No irrigation or disease control measures are planned at this time. Pest control will primarily involve control of noxious weeds. The noxious weeds that have been identified on sife are White Top, Russian Knapweed and Tamarisk. If noxious weed infestations occur at levels which may interfere with successful revegetation or are detrimental to stand quality, weed control using herbicides will be implemented. White Top and Russian Knapweed will be sprayed with Curtail, 2.0 oz/gallon. It will not be applied when spray particles maybe carried by air currents to areas where desirable plants are growing. Russian knapweed should be sprayed in the spring and fall. White Top must be sprayed in early spring. Spraying will be done by use of a backpack spray system or an ATV mounted spray tank • Vegetation at the North Decline is dominated by cheatgrass to the detriment of other more desirable grasses. During the fall of 2005 and 2006, cheatgrass at the North Decline will be sprayed with the herbicide Plateau, in accordance with the manufacturer's recommendations, at the rate of 6 ounces per acre, Approximately three weeks after the second treatment, the treated areas will be interseeded with the seedmix presented on Table 14-14. The Operator intends to initiate Tamarisk control in permanently regraded and seeded areas beginning in the fall of 2005. Tamarisk control will begin at the south end of overland conveyor corridor, west of the river. During ensuing years, the Operator will carry out a modest Tamarisk control program. Tamarisk will be controlled by mechanical removal or by cutting the stem and applying herbicide (known as the cut-stump method). Individual tamarisk plants will be cut as close to the ground as possible and herbicide will be applied immediately thereafter to the perimeters of the cut stems. The herbicides used will be triclopyr (e.g. Garlon4 or Pathfinderll) or imazapyr (Arsenal). Fall treatments are believed to be most effective because the plants are translocating materials to their roots. U 14-17 (Rev. 10/05)
