MEMO to All Minerals Staff <br />December 17, 2002 -Weed Control Policy <br />Page 3 <br />4. Regulated Noxious Weeds: <br />The following plants are considered to be noxious weeds for the purposes ofthis guideline and the Hard <br />Rock and Construction Material Regulations. It should be recognized that the following list may not <br />include noxious weed species that are specific to a particular county or of particular State interest. <br />Operators should check with the county in which their particular mining site is located for additional <br />weed species. <br />Common Name <br />Leafy spurge <br />Canada thistle <br />Musk thistle <br />Plumeless thistle <br />Scotch thistle <br />Perennial Sowthistle <br />Russian knapweed <br />Spotted knapweed <br />Diffuse knapweed <br />Yellow toadflax <br />Dalmation toadflax <br />Scientific Name <br />Euohorbia esula <br />Cirsium arvense <br />Cazduus nutans <br />Carduus acanthoides <br />Onopordum acanthium <br />Sonchus arvensis <br />Centaurea repens <br />Centaurea maculosa <br />Ceutaurea diffusa <br />Linazia vulgaris <br />L. ¢enistifolia dahnatica <br />or L. dalmatica macedonia <br />Perennial peperweed <br />Hounds tongue <br />Hoary cress (White Top) <br />Field bindweed <br />5.

However, in most cases it is the responsibility of the individual Environmental <br />Protection Specialist (EPS) to evaluate the site proposed for release and determine ifthe site has met the <br />reclamation requirements of the Act, Regulations, and the approved permit. In terms of infestations of <br />noxious weeds, the Division will follow its standard fmancial warranty release process. Any agency or <br />person that objects to the Division's decision may appeal that decision to the Boazd as allowed for in the <br />Acts and Rules that address Aappeals to an agency decision". <br />In making the decision to release the site where noxious weeds occur, the EPS shall consider the likely <br />impact to the long term stability and utility of the site given the level of noxious weed occurrences on <br />and off site. If the site is surrounded by an infestation of noxious weeds, a higher level of noxious weed <br />occurrence at the site should be allowed. Tn pristine areas (visually free of noxious weeds) no noxious <br />weeds should be left untreated. Take into consideration that an established native plant community, if it <br />is the dominant vegetative expression at the site, maybe resistive enough to prevent the spread, or <br />
