4.5.404    STANDARD RANGE OF TOLERANCES FOR NOXIOUS WEEDS

(1) The tolerance for noxious weeds in noxious weed free material is zero for the weeds defined in 7-22-2101(7)(a)(i), MCA, and any other weed species prohibited by a regulated area. 

(a) For a site, this means that an agent finds no noxious weed plants present in the site or established buffer area at the time of inspection following the standard inspection procedures.

(b) For mulch, gravel, and other materials this means that materials are 98% free of viable additional weeds following the standard inspection procedures.

(2) For purposes of these rules, the department's certification represents the condition of the site at the time of certification.  Further cautionary restrictions with respect to processing, storage, and transportation are imposed in these rules to help preserve that certification.  However, the rules do not intend or provide for any further visual or other inspection of the certified materials after the point of initial certification, other than that which may occur as a result of enforcement or other related activity.
