APPENDIX II <br /> Noxious Weed Control Plan <br /> SEMA Construction Company(SEMA) will comply with the State of Colorado, weld County, and <br /> as necessary, the City of Aurora Noxious Weed Control regulations. <br /> SEMA will utilize the following mechanical and chemical methods to control noxious weeds: <br /> Field Mowing: <br /> Prior to noxious weeds reaching full maturity(producing flowers/going to seed), the weeds shall <br /> be mechanically mowed to a height of 4" to 6" where such activity will not pose a hazard to <br /> equipment or equipment operators. This should be performed twice during the growing season in <br /> late spring and late summer. Additional mowing will be performed as necessary. <br /> Chemical Control: <br /> One initial application of an appropriate selective herbicide shall be applied, per manufactures <br /> recommendations, or by a certified applicator for control of noxious weeds. Application shall be <br /> done during the growth stage and when temperatures and other conditions are appropriate to <br /> achieve the most effective control. Follow-up applications will be done as needed. <br /> SEMA will conduct routine surveys to identify noxious weeds and make timely arrangements for <br /> control and treatment. SEMA will keep a record of sites needing noxious weed control. <br /> 57 <br />
