~x~~PL ~ <br />Otherwise the site is mostly pastureland with grass and annual weeds in a condition <br />similar to when it was acquired. During the June 19, 2006 inspection DRMS noted <br />Diffuse Knapweed (Centaurea diffuse) end Scotch Thistle (Onopordum taurictun) es <br />being prevttlcnt around the North, South, and East perimeter of the site. The Division <br />noted the problem (Rule 3.1.10(6)) and directed submittal and implementation of a Weed <br />Control Technical Revision (TR). <br />During a subsequent site inspection by the Douglas County Weed Inspector (DCWn, <br />Jonathan Rife, at the Stevens Mine on August 29, 2006, noted Canada Thistle (Cirsium <br />an+ense), which is an additional noxious weed other than the weeds noted above was at <br />scaturcd locatioru on the Stevens Minc site. <br />This Wced Control Plan has beta developed w attempt to address all the noxious weed <br />control issues noted by DRMS and DCWI to date. <br />METHODOLOGY <br />Areas infested with the identified noxious weeds within the permit boundary will be <br />addressed by initial assessment and spraying by a contractor with appropriate experience <br />in these matters. The qualified contractor will deem the liquid application(s) appropriate <br />end Acme Brick Company proposq to inform DRMS of weed control activities on an <br />annual basis as part of the permit Annual Report fiutction and requirements. <br />Acme Brick Compmy envisions this is an annual ongoing process during each spring to <br />control noxious weeds before they propagate during the summer season. Specific <br />management techniques will be developed, implemented and documented using n <br />practical mix of cultural, mechanical, biological end chemical controls es dcemed both <br />effective and cost-effective. <br />[n general, the thistles and DifTilse Knapweed will probably be controlled using <br />herbicides, particularly during the leaf development stage, but before the flowering stage <br />in early June. Thistles and Diffuse Knapweod will be treated in accordance with the <br />DCWI guidaace, attached. <br />Further we plan to implerttent the plan as an integrated approach incorporation additiottel <br />weed control measures such as mowing, spot seeding, field harrowing, grazing, etc., <br />which will be evaluated and implemented in conjunction with spraying a, dcemed <br />nppropriate in consultation with our weed control subcontractor. If standard measures are <br />not successful in eliminating the weed control problem within s reasonable amount of <br />time (approximately one to four seasons of treatment) Acme Brick Company mny contact <br />DRMS for additional assistance. <br />
