Weed Monitoring Plan <br />The operator commits to performing weed inspections three (3) times per growing <br />season, as follows: April, July, and October, using the attached "Weed Inspection <br />Report". Individuals who have been trained to identify noxious weeds will conduct the <br />inspections. If weeds are found, their location will be marked on a site map to be kept <br />with the reports, and a plan for elimination and containment will be implemented using <br />the guidelines below. Copies of these inspection reports will be kept on site for a period <br />of three years from inspection date. <br />Weed Control Measures <br />If noxious weeds are encountered on site, they will generally be controlled as follows. <br />The operator will contact weed control specialists to recommend herbicides or other <br />chemical control, if necessary. If significant infestations are discovered or the control <br />measures specified below appear to be ineffective, the operator will consult with County <br />weed management personnel for further guidance. <br />Myrtle spurge: Myrtle spurge will be controlled by the direct application of herbicides <br />and/or hand-pulling and digging. If the plants have been hand-pulled or <br />dug, they will be bagged and sent to the landfill. <br />Spotted knapweed: Spotted knapweed will be controlled by the direct application of herbicides <br />and/orhand-pulling and digging. If the plants have been hand-pulled or <br />dug, they will be bagged and sent to the landfill. <br />Cypress spurge: Cypress spurge will be controlled by the direct application of herbicides <br />and/orhand-pulling and digging. If the plants have been hand-pulled or <br />dug, they will be bagged and sent to the landfill. <br />Purple loosestrife: If Purple loosestrife is found, the seed heads will be cut off and bagged to <br />prevent seeds from falling on the ground, and/or an aquatic chemical <br />control will be applied depending on the extent of infestation. <br />Russian knapweed: To control this plant, stress the roots by mowing and spraying. Mow at 2 <br />to 3 week intervals over the season followed by fall chemicals. Plant <br />perennial grasses in the fall to help keep noxious weeds from growing <br />back. Fertilize and irrigate the area to stimulate competitive grasses. <br />Canada thistle: To control this plant, stress the roots by mowing and spraying. Mow at <br />least 3 times at 2-week intervals; do not let it produce seeds. Spray <br />emerging spring plants and those after first frost. Plant dry-land foliage, <br />irrigate and plant perennial grasses in the fall and fertilize. Tilling is not <br />recommended because it breaks up the roots and stimulates new plants <br />without photosynthesis. <br />Diffuse knapweed: To control this plant, keep it from going to seed. The pulling and spraying <br />of the weeds will help with controlling, along with planting perennial <br />grasses in the fall. <br />Jemadojin Sand Mine May 2006 <br />Weed Management Plan Page 2 <br />
