§2.05 APPLICATION FOR PERMIT FOR SURFACE OR UNDERGROUND MINING <br />ACTIVITIES -MINIMUM REQUIREMENTS FOR OPERATION AND RECLAMATION <br />PLANS. <br />(iv) Mulching Techniques <br />Straw mulch will not be applied to the irrigated field. It will only <br />be utilized on small areas that cannot be irrigated. <br />A straw mulch will be used to provide surtace protection and <br />store moisture during the first growing season. The application <br />rate will be about 4,000 pounds per acre. Only clean grain <br />straw that is free of noxious or problem weeds will be used. <br />The straw will be anchored by mechanical crimping, <br />polypropylene erosion control netting or with one of the various <br />tackifying agents available on the market. <br />(v) Irrigation, if appropriate and pest and disease control <br />Irrigation is planned for the regraded and revegetated areas to <br />help establish and maintain plant growth consistent with the <br />postmining land use. During the first few growing seasons, a <br />sprinkler system or a gated pipe system with contour creases <br />may have to be utilized to control erosion. After the vegetation <br />is well established, flood irrigation techniques will be employed. <br />Weed Control <br />This weed control plan is concerned with the control of all <br />varieties of noxious weeds on the mine site. It was developed <br />in coordination with Webb Callicutt, Coordinator, Delta County <br />Noxious Weed Program. Noxious weeds of concern in the <br />general location of the Bowie No. 2 Mine permit area are; 1) <br />Russian knapweed, Musk, Canadian and Scotch thistle, <br />Houndstounge, Oxeye Daisy and Yellow toadflax. <br />Yellow toadflax can be spayed anytime it is discovered. Spay <br />with Banvel, 1.5 oz/gal. <br />TR-020 <br />2.05 - 26 <br />3/01 <br />
