PROPOSED RULES

DEPARTMENT OF AGRICULTURE


[ Filed July 22, 2009, 7:53 a.m. ]

     Original Notice.

     Preproposal statement of inquiry was filed as WSR 09-10-034.

     Title of Rule and Other Identifying Information: Chapter 16-752 WAC, Noxious weed control, the department is proposing to amend chapter 16-752 WAC by:

     (1) Adding additional species to the wetland and aquatic weed quarantine (floating primrose-willow, variable-leaf milfoil, ricefield bulrush, and water soldier);

     (2) Adding additional species to the noxious weed seed and plant quarantine (false brome, shiny geranium, and European hawkweed);

     (3) Revising permit requirements for educational or training materials;

     (4) Adding language regarding botanical synonyms; and

     (5) Increasing its clarity and readability by removing obsolete definitions and updating the language.

     Hearing Location(s): Washington State Department of Agriculture, Natural Resources Building, Conference Room 205, 1111 Washington Street S.E., Olympia, WA 98504-2560, on August 27, 2009, at 11:00 a.m.

     Date of Intended Adoption: September 3, 2009.

     Submit Written Comments to: Henri Gonzales, P.O. Box 42560, Olympia, WA 98504-2560, e-mail hgonzales@agr.wa.gov, fax (360) 902-2094, by August 27, 2009.

     Assistance for Persons with Disabilities: Contact Henri Gonzales by August 20, 2009, TTY (800) 833-6388.

     Purpose of the Proposal and Its Anticipated Effects, Including Any Changes in Existing Rules: The department is proposing to amend the noxious weed control rule by: Adding additional species to the wetland and aquatic weed quarantine; adding additional species to the noxious weed seed and plant quarantine; revising permit requirements for educational or training materials; adding language regarding botanical synonyms; and increasing its clarity and readability by removing obsolete definitions and updating the language.

     The purpose of enacting these and other quarantines is to prevent the establishment and spread of harmful nonnative species. Once established, they can have a serious impact on Washington's natural resources by displacing native species, altering habitat, reducing recreational use of waterways, and impacting agricultural production.

     Reasons Supporting Proposal: The intrusion into this state of nonnative, invasive weed species continues to be a concern. The spread of these weeds presents a risk to the economic well-being of the agricultural, forest, horticultural, and floricultural industries, and the environmental quality and natural resources of the state. Initiating quarantines forbidding entry or distribution of weed species may be critical for their exclusion or control.

     Statutory Authority for Adoption: Chapters 17.10, 17.24, and 34.05 RCW.

     Statute Being Implemented: Chapters 17.10 and 17.24 RCW.

     Rule is not necessitated by federal law, federal or state court decision.

     Name of Proponent: Washington state department of agriculture, governmental.

     Name of Agency Personnel Responsible for Drafting, Implementation and Enforcement: Tom Wessels, 1111 Washington Street, Olympia, WA 98504-2560, (360) 902-1984.

     No small business economic impact statement has been prepared under chapter 19.85 RCW. RCW 19.85.030 (1)(a) requires that an agency must prepare a small business economic impact statement (SBEIS) for proposed rules that impose a more than minor cost on businesses in an industry. Of the seven species of invasive plants these amendments would prohibit from distribution, only one (variable-leaf milfoil) is sold commercially as an aquarium plant. We were able to identify a sole commercial grower in this state who grows this species and were told by that grower that prohibiting the plant would not have a more than minor impact, as there are several alternative species readily available in commerce. Analysis of the economic effects of the proposed rule amendments demonstrates that the changes will not be more than a minor cost to small business in the regulated industry and, therefore, an SBEIS is not required. However, failure to adopt these changes has potential to have a large negative economic impact on the state, due to the cost of eliminating these species if they were to become established.

     A cost-benefit analysis is not required under RCW 34.05.328. The Washington state department of agriculture is not a listed agency under RCW 34.05.328 (5)(a)(i).

YELLOW NUTSEDGE QUARANTINE
AMENDATORY SECTION(Amending WSR 03-16-038, filed 7/30/03, effective 8/30/03)

WAC 16-752-300   Yellow nutsedge -- Establishing quarantine.   Yellow nutsedge (Cyperus esculentus L.) is a herbaceous perennial that is one of the most serious noxious weeds of agronomic crops. It propagates by seed, rhizomes, bulbs, and nutlets. Soil containing nutlets is the primary mode of spread in cultivated land. It is highly invasive and its unchecked spread would entail great economic loss to the agricultural industries of the state. It is a class B noxious weed designated for control in Thurston County (WAC 16-750-011 (((33))) (49)(a)). Yellow nutsedge infests a plant nursery site at the Port of Olympia in Tumwater, Washington. Movement of material from this site initiates additional infestations. RCW 17.10.210 provides that either the director or the county noxious weed control board or a weed district may issue an order for quarantine and restriction or denial of access to land determined to be so seriously infested that control measures cannot be undertaken without quarantine of the land. The director has determined:

     (1) That the identified site is so seriously infested as to require quarantine; and

     (2) That the movement of contaminated materials from this site presents an immediate threat of infestation to the rest of the county agricultural and nonagricultural areas; and

     (3) That the restriction of such spread is critical to control efforts.

WAC 16-752-400   Establishing quarantine.   The Lythrum ((species)) genus (Purple loosestrife) is an aggressive, semiaquatic, herbaceous perennial weed that has infested wetlands in the state of Washington causing serious harm to native plants and destroying habitat for birds and small mammals.
