WSR 98-20-094
PROPOSED RULES
NOXIOUS WEED CONTROL BOARD
[Filed October 7, 1998, 10:24 a.m.]
Original Notice.
Preproposal statement of inquiry was filed as WSR 98-12-069.
Title of Rule: Chapter 16-750 WAC, State noxious weed list and schedule of monetary penalties.
Purpose: The state Noxious Weed Control Board proposes amending the state noxious weed list to add species determined to be noxious, to change areas designated for control of some noxious weeds and to delete certain noxious weeds from the list. The board also proposes changing its mission statement.
Statutory Authority for Adoption: Chapter 17.10 RCW.
Statute Being Implemented: Chapter 17.10 RCW.
Summary: Proposed changes to the state noxious weed list include the addition of two new Class A noxious weeds, one new Class B noxious weed and one new Class C noxious weed; the deletion of six species; and classification and designation area changes for fifteen species. The state weed board mission statement would also be edited.
Reasons Supporting Proposal: New nonnative species were found to be highly destructive, competitive or difficult to control. Distribution data indicated some listed species should be reclassified or deleted.
Name of Agency Personnel Responsible for Drafting: Lisa E. Lantz, Kent, Washington, (253) 872-2972; Implementation: Ray Fann, Kent, Washington, (253) 872-2972; and Enforcement: Mary A. Martin Toohey, Olympia, Washington (360) 902-1907.
Name of Proponent: Washington State Noxious Weed Control Board, governmental.
Rule is not necessitated by federal law, federal or state court decision.
Explanation of Rule, its Purpose, and Anticipated Effects: The state noxious weed list provides the basis for noxious weed control efforts by county noxious weed control boards, weed districts, the state weed board and the Washington State Department of Agriculture, under the auspices of chapter 17.10 RCW. The effect of the state noxious weed list is to prioritize control of noxious weed species statewide, concentrating on prevention and early detection, while still allowing for local program flexibility.
Proposal Changes the Following Existing Rules: The proposal adds two new Class A weeds, one new Class B weed, and one new Class C weed. It also deletes six species and changes the classification or designation area for fifteen listed species. The proposal would also revise the State Noxious Weed Control Board's mission statement.
A small business economic impact statement has been prepared under chapter 19.85 RCW.
Small Business Economic Impact Statement
Background: The Washington State Noxious Weed Control Board (WSNWCB) is charged with annually reviewing and updating the state noxious weed list, found in chapter 16-750 WAC, to ensure it accurately reflects and prioritizes the noxious weeds threatening Washington.
The WSNWCB issued a call for suggestions and recommendations on the content of the state noxious weed list in December of 1997 to all county noxious weed control boards and an extensive mailing list of agricultural and environmental organizations, state and federal agencies, county governments, and other parties who have asked to be notified of such opportunities. This comment period was open until the end of April 1998. An additional reminder notice was sent during the comment period. A handout was also provided, which included tips for making a successful recommendation.
The WSNWCB Noxious Weed Committee, which is composed of scientific advisors, county representatives, WSNWCB representatives, and a public interest representative, first met in May of 1998 to review the suggestions received to date. Committee meetings are open to the public and suggestions can be presented in person or in writing. The committee then used the next few months to gather additional information needed to evaluate suggestions. This process includes field investigations, literature searches, interviews with scientists and weed specialists in other areas of the country or world, and additional interviews with persons making recommendations.
The committee held another public meeting in July 1998 to finish evaluation of suggestions and to review additional suggestions that had been submitted outside of the formal comment period. The committee then developed a draft set of recommendations for changes to the state noxious weed list. The preproposal statement was filed in June and the draft amendments were sent out for comment in August of 1998.
The Noxious Weed Committee met a third time in September to consider public input and to finalize its recommendations to the WSNWCB. After discussion and review of the committee's recommendations, the WSNWCB adopted the recommended changes to the state weed list as their formal proposal in September 1998.
Summary of Amendments: The following changes are proposed:
WAC 16-750-005 State noxious weed list - Class A noxious weeds. Class A noxious weeds are required to be eradicated by all landowners under the authority of chapter 17.10 RCW.
Add two new nonnative species that are of extremely limited distribution and are highly destructive, competitive, or difficult to control (Thymelaea passerina and Euphorbia oblongata).
Delete two nonnative species (Hibiscus trionum and Proboscidea louisianica). Recent evaluation indicates these species have not been highly destructive, competitive, or difficult to control in Washington.
Move one species found to have an extremely limited distribution from the Class C list to the Class A list (Tamarix ramosissima).
Move one species from the Class A list to the Class B list (Hieracium pilosella). The increased distribution of this species makes it more appropriate on the Class B list.
WAC 16-750-011 State noxious weed list - Class B noxious weeds. Class B noxious weeds are required to be controlled by all landowners in the areas where they are designated, under the authority of chapter 17.10 RCW. In the areas where they are not designated, landowners are only required to control Class B noxious weeds if they are placed on the county noxious weed control list, as a local priority for control.
Designate new areas for the mandatory control of nine previously listed species, each in only two counties or a smaller area (Chondrilla juncea, Geranium robertianum, Kochia scoparia, Lepidium latifolium, Linaria dalmatica ssp. dalmatica, Lysimachia vulgaris, Lythrum salicaria, Lythrum virgatum, and Ulex europaeus). These species have been found to have only limited distribution in the areas where they are proposed for designation, making control and containment feasible.
Move four species from the Class C list to the Class B list (Anthriscus sylvestris, Chaenorrhinum minus, Daucus carota, and Eruca vesicaria ssp. sativa). These species have been found to have only limited distribution in the areas where they are proposed for designation, making control and containment feasible.
Move one species from the Class A list to the Class B list (Hieracium pilosella). The increased distribution of this species makes it more appropriate on the Class B list. This species has been found to have only limited distribution in the areas where it is proposed for designation, making control and containment feasible.
Add one new nonnative species that is highly destructive, competitive, or difficult to control (Impatiens glandulifera). The species is designated for control where it is unknown or of limited distribution.
Delete one nonnative species (Lamium hybridum). Recent reevaluation indicates this species has not been highly destructive, competitive, or difficult to control in Washington.
WAC 16-750-015 State noxious weed list - Class C noxious weeds. Class C noxious weeds are widespread species that are not state-mandated for control under the authority of chapter 17.10 RCW. Landowners are only required to control Class C noxious weeds if they are placed on a county noxious weed control list, as a local priority for control.
Add one, new, nonnative species that is highly destructive, competitive, or difficult to control (Polygonum sachalinense).
Move one species found to have an extremely limited distribution from the Class C list to the Class A list (Tamarix ramosissima).
Move four species from the Class C list to the Class B list (Anthriscus sylvestris, Chaenorrhinum minus, Daucus carota, and Eruca vesicaria ssp. sativa). These species have been found to have only limited distribution in some areas, making control and containment feasible.
Delete three widespread species (Cirsium vulgare, Solanum dulcamara, and Verbascum thapsus).
WAC 16-750-110 State Noxious Weed Control Board - Mission. Revise mission statement to be more concise and to be consistent with changes to RCW 17.10.007.
Costs of Compliance: Changes to the state weed board mission statement and deletion of species from the state noxious weed list should have very little economic impact to businesses. The addition of new noxious weeds to the state noxious weed list or the designation of noxious weeds in new areas of the state impose potential costs on all businesses that own or manage infested property. These costs are only incurred if the listed species occur on the property. By definition, the noxious weeds for which the state requires control are of limited distribution and, therefore, only a relatively small number of businesses will actually incur noxious weed control costs in any one season.
The control of noxious weeds involves costs for the actual control strategy selected, as well as some administrative time for recordkeeping, compliance correspondence, training, and safety education for some control strategies. The state's noxious weed law, chapter 17.10 RCW, does not mandate a specific method of control; it mandates a result. The landowner can select the method he/she feels is most appropriate, after considering site characteristics, cost, time, and effectiveness. Technical assistance in choosing a control strategy is available to all landowners at no cost from the local county noxious weed control board or weed district, Washington State University Cooperative Extension, the Washington State Department of Agriculture, and the WSNWCB. Control costs will vary widely, based on the noxious weed, the site's environmental characteristics, weather, the extent of the vegetation, the surrounding land use, and the control strategy used.
Chemical control strategies involve costs for the following items. These control cost ranges capture the majority of control situations, but some sites may have higher or lower costs:
Herbicides - $15 to $100 per acre.
Application equipment - spot spray with a pre-mixed chemical $0, hand held sprayer $15 to $45, backpack sprayer $60 to $100 new (may be available for loan from county weed board), truck mounted spray rig and boom $500 to $5,000 (not including vehicle).
Labor - in-house or contracted with a licensed applicator (who would handle equipment, licensing, permitting, and recordkeeping) $20 to $100 per hour contracted applicator; aerial application $150 to $250 per hour.
Protective equipment - goggles $3 to $10, chemical-resistant gloves $5 to $40, chemical-resistant boots $20 to $60, Tyvek coveralls $3 to $12. Personal protective equipment costs will vary depending on the type of herbicide and the frequency and duration of use.
Licensing and permitting - application of many herbicides requires the applicator to be licensed and permits may be required for some types of sites (mainly those in or near water) - $21 to $40 for license and study materials, $20 to $500 for permit notices and signage.
Recordkeeping - fifteen minutes to two hours of labor time, depending on the extent and variability of the application.
Hand-pulling or mowing costs include: Labor - hand methods may require two to ten times more labor time than chemical strategies.
Equipment - hand tools $5 to $40 each for shovels, hoes, weed whip; $35 to $250 for hand-held trimmers.
Disposal - bags fifty cents to $4 each, land-filling $15 to $100/ton.
Other strategies like burning, steam solarization, tillage, etc. may be appropriate for some sites, but the previous two methods are the most commonly used.
Comparison of Cost - Small Versus Large Employers: Administrative and control costs vary only with the control strategy selected, the site characteristics, and the type and extent of the infestation. These costs on a per acre basis would be the same for small and large employers, but could be proportionally more per employee for small employers. The cost to outfit, train, and equip one employee for noxious weed control work would depend on the number of employees needed to conduct the control work, but this may represent a larger percentage of employees for small businesses. Contracting for control work could cost more per hour of labor or per $100 of sales for a small employer. Larger businesses would be expected, in general, to own or manage more land, thus potentially incurring a higher total cost.
The proposed amendments affect a small percentage of landowners in Washington. It is highly unlikely they would affect more than 20% of all industries or more than 10% of any one industry. The species proposed for the Class A list are all presently known from four or fewer sites in the state. The proposed changes to the B list would also affect limited numbers of landowners; these changes are proposed because the species are present in limited areas or present at very small levels of infestation.
Mitigation of Disproportionate Costs to Small Employers: The state noxious weed law recognizes that the immediate prevention, control, and eradication of noxious weeds is practical on some lands and that these activities should be extended over a period of time on other lands. RCW 17.10.154 allows county noxious weed control boards, at their discretion, to enter into agreements with local landowners. These agreements allow for gradual containment and control of noxious weeds over a period of years on appropriate sites. This flexibility allows small businesses to spread noxious weed control costs over time in some cases.
Due to site conditions and infestation patterns, mitigation of control requirements for small businesses may not always be possible. Noxious weeds do not recognize human political and ownership boundaries. Effective control statewide requires that all landowners fulfill the requirements to control and contain noxious weeds. This is an inherent part of all pest control programs. Through the state noxious weed list, the state has prioritized control efforts in Washington, concentrating landowner efforts on new infestations. Control of infestations when they are small provides the most protection for the least cost. County noxious weed control boards limit landowner costs by conducting regular surveys so that infestations can be caught when small. Technical assistance is also available through several sources to assist landowners in devising the most effective and cost-efficient control program possible.

WAC 16-750-110 State noxious weed control board--Mission.
The mission of the board is to serve as responsible stewards ((of
the land and resources)) of Washington by protecting and
preserving the ((agricultural)) land((s)) and ((natural))
resources ((of the state)) from the degrading impact of ((exotic,
invasive)) noxious weeds.
The board believes that prevention is the best approach and may be achieved through full implementation of the intent of the state noxious weed law. To further that, the board strives for enhanced public awareness through improved educational efforts.
The board does not deal directly in control activities but rather works to achieve this end through others. For that reason, the board seeks to improve communication, gain cooperation, and improve coordination of the efforts for noxious weed control.
The board believes noxious weed control is best carried out by strong, adequately funded programs at the local level. To achieve this, the board strives to build public support for local programs and to empower those programs to be more successful.
