2018 Colorado Revised Statutes
Title 35 - Agriculture
Pest and Weed Control
Article 5.5 - Colorado Noxious Weed Act
§ 35-5.5-108. Designated noxious weeds - rules - legislative declaration
(1) The general assembly hereby finds and declares that the noxious weeds designated by rule are a present threat to the economic and environmental value of the lands of the state of Colorado and declare it to be a matter of statewide importance that the governing bodies of counties and municipalities include plans to manage such weeds as part of their duties pursuant to this article.
(2) (a) The state list of plant species that are designated as noxious weeds shall be designated by rule and shall be managed under the provisions of this article. On and after August 6, 2003, the commissioner shall classify noxious weeds into one of a minimum of three categories, including:
(I) "List A", which means rare noxious weed species that are subject to eradication wherever detected statewide in order to protect neighboring lands and the state as a whole;
(II) "List B", which means noxious weed species with discrete statewide distributions that are subject to eradication, containment, or suppression in portions of the state designated by the commissioner in order to stop the continued spread of these species;
(III) "List C", which means widespread and well-established noxious weed species for which control is recommended but not required by the state, although local governing bodies may require management.
(b) A local governing body may adopt eradication, containment, or suppression standards that are more stringent than the standards adopted by the commissioner.
(2.1) The commissioner shall review and revise, as necessary, the state noxious weed list at least once every three years.
(2.3) The commissioner shall develop and implement by rule state noxious weed management plans for noxious weed species classified as list A or list B species. For each noxious weed species, each management plan shall designate the management objectives for all lands of the state appropriate to achieve the stated purpose of the species classification.
(2.5) The commissioner shall prescribe integrated management techniques to achieve specified management objectives for each listed species after consulting with the state noxious weed advisory committee. The prescribed management techniques shall be mandatory techniques for list A species and populations of list B species designated for eradication. The commissioner shall develop management techniques pursuant to science-based methodologies, peer reviewed studies, or any other method that is based on credible research.
(2.6) The classifications made pursuant to paragraph (a) of subsection (2) of this section shall primarily reflect the known distribution of the designated species, the feasibility of current control technologies to achieve specified management objectives, and the costs of carrying out the prescribed state weed management plan.
(2.7) (a) The commissioner shall also adopt rules for granting compliance waivers to local governing bodies and landowners; except that a waiver may not be granted to the affected landowner when a landowner has wilfully or wantonly violated the provisions of this section or section 35-5.5-104.5 or 35-5.5-108.5 attempts to delay eradication of a species without just cause.
(b) Such rules shall include:
(I) A process by which a local governing body or an affected landowner may petition the commissioner to change the management objectives specified in a state noxious weed management plan;
(II) The criteria used to evaluate such petitions; and
(III) Time frames in which the commissioner shall grant or deny such petitions.
(c) Actions sufficient to implement the management objective for a noxious weed species shall continue until the commissioner grants a waiver pursuant to this subsection (2.7).
(3) The board of county commissioners or governing body of a municipality may declare additional noxious weeds, within its jurisdictional boundaries, after a public hearing with thirty days prior notice to the public. Any declaration of additional noxious weeds pursuant to this subsection (3) shall include the management objectives for all affected landowners.
