. 2.05.4(2)(e) <br />During 1992, eighteen acres of the backfilled area within Mining Area 1 <br />were covered with topsoil. Because of inclement weather during the fall of 1992, <br />the rangeland seed mix was not applied to the topsoiled area. The Operator <br />does not believe that the rangeland seed mix will establish if planted during the <br />spring of 1993. For this reason, a cover crop will be planted on the topsoiled <br />area in the spring of 1993. The topsoiled areas will be seeded with rangeland <br />seed mix in the fall of 1993. <br />MULCHING TECHNIQUES: <br />A straw mulch will be used to provide surface protection; the application <br />rate will be approximately 4000 pounds/acre. The straw will be anchored by <br />mechanical crimping or with one of the various tackifying agents available on the <br />market. Only clean grain straw that is free of noxious or problem weeds will be <br />used. <br />IRRIGATION AND WEED CONTROL: <br />Use of the planting and mulching methods specified above will result in <br />• satisfactory plant establishment, barring abnormally dry conditions. There are no <br />plans to irrigate the reclaimed areas. <br />At the time of this writing, 2006, noxious weeds of concern in the general <br />area that have been identified are White Top, Canada Thistle, Russian <br />Knapweed, Tamarisk, and Russian Olive. At the request of the Division, the <br />Operator's efforts are being formalized with the following weed control plan. <br />This weed control plan is concerned with the control of all varieties of <br />noxious weeds on the mine site. It was developed based on recommendations <br />by Laurie Felix, Montrose County weed Manager. <br />Whitetop will be sprayed with Dupont Escort, 1-2 oz/acre mixed with a <br />non-ionic surfactant at 1 quart per 100 gallons. It will not be applied when spray <br />particles may be carried by air currents to areas where desirable plants are <br />growing. Spraying will be done by use of a backpack spray system or an ATV <br />mounted spray tank. <br />Whitetop should be treated in the Spring between mid-April and mid-May <br />in the pre-flower stage. <br />Canada Thistle will be sprayed with Curtail, 2 quarts/acre mixed with a <br />• non-ionic surfactant at 1 quart per 100 gallons of spray. It will not be applied <br />when spray particles may be carried by air currents to areas where desirable <br />plants are <br />2.05-25 03/06 <br />
