in these matters. The liquid application(s) will be as deemed appropriate by the qualified <br />contractor and Botal/Ready Mixed proposes to inform DRMS of weed control activities <br />on an annual basis as part of the permit Annual Report function and requirements. <br />BoraUReady Mixed is currently in negotiations to select a preferred subcontractor and <br />proposes to begin inventory and spraying activities before the end of this month. Fall <br />weed control activities will be followed by spring evaluations and possible additional <br />treatments before remaining weeds can go to seed next yeaz. We envision this as an <br />annual ongoing process during each spring to control noxious weeds before they <br />propagate during the summer season. Specific management techniques will be <br />developed, implemented and documented using a practical mix of culture(, mechanical, <br />biological and chemical controls as deemed both effective and cost-effective. <br />In general the thistles, leafy spurge and diffuse knapweed will generally be controlled by <br />aggressive summer mowings followed by fall herbicide treatment. Field bindweed will <br />probably be generally controlled using herbicides, particulazly during the flowering stage <br />in eazly summer. Tamarisk (and Russian olive if encountered) will be treated in <br />accordance with the DRMS guidance, attached. <br />Further we plan to implement the plan as an integrated approach incorporation additional <br />weed control measures such as mowing, plowing, hand-pulling, grazing, etc., which will <br />be evaluated and implemented in conjunction with spraying as deemed appropriate in <br />consultation with our weed control subcontractor. If such standard measures are not <br />successful in eliminating the weed control problem within a reasonable amount of time <br />(approximately one to tlu~ee seasons of treatment) BoraUReady Mixed may contact <br />DRMS for additional assistance. With the assistance already provided by DRMS the <br />plant manager and our permitting consultant are already better educated about weed <br />identification at the site. We will continue to develop these recognition skills and attempt <br />to incorporate noxious weed identification and observation into our daily activities at the <br />site [o maximize Ute impact of our weed control efforts. <br />By reference and incorporation on the following pages, the following documents are <br />included in this Weed Control Plan Technical Revision: <br />1.
