Original Notice.

Preproposal statement of inquiry was filed as WSR 02-05-089.

Title of Rule: Rules relating to noxious weed seed and plant quarantine, chapter 16-752 WAC.

Purpose: Amendment of existing rule to add a single species of nonnative, highly invasive plant to the quarantine list of species forbidden from sale or distribution in the state.

Statutory Authority for Adoption: Chapters 17.24, 17.10, 15.13 RCW.

Statute Being Implemented: Chapters 17.24, 17.10, 15.13 RCW.

Summary: Amendment of the existing noxious weed seed and plant quarantine rule to add kudzu to the list of species forbidden from sale or distribution in the state was requested by the Washington State Noxious Weed Control Board and the Washington State Weed Coordinators Association. The quarantine is intended to aid in prevention of kudzu introduction and spread in this state.

Reasons Supporting Proposal: Kudzu, Pueraria montana var.lobata, is an extremely invasive woody vine weed species that has caused severe economic and environmental problems in the southeastern United States. In August 2001, a small, rapidly growing infestation was discovered and eradicated in Clark County, demonstrating it can survive in this state.

Name of Agency Personnel Responsible for Drafting: Mary Toohey, 1111 Washington Street, Olympia, WA 98504-2560, (360) 902-1907; Implementation and Enforcement: Tom Wessels, 1111 Washington Street, Olympia, WA 98504-2560, (360) 902-1984.

Name of Proponent: Washington State Weed Coordinators Association, Washington State Noxious Weed Control Board, private and governmental.

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

Explanation of Rule, its Purpose, and Anticipated Effects: A very small infestation of kudzu, a nonnative, highly invasive weedy vine, was found in Clark County in August 2001. The infestation was eradicated, but it persisted long enough to demonstrate that this species, which has caused economic and environmental devastation in the southeastern United States, is capable of long-term survival in Washington state. Oregon is currently attempting to eradicate several infestations. The proposed amendment to the rule would add kudzu to the existing list of plant species forbidden from sale or distribution in this state. This would aid in preventing the establishment of a highly undesirable species, preventing harm to native species, alteration of ecosystems, and economic harm to agricultural and nursery industries and to maintained landscapes.

Proposal Changes the Following Existing Rules: The proposal adds one highly invasive, nonnative plant species, kudzu, to the existing list of quarantine species which are forbidden from sale or distribution in this state.

No small business economic impact statement has been prepared under chapter 19.85 RCW. Kudzu, the sole species proposed for addition to the quarantine list, has been eradicated from the state and currently is not known to be distributed or offered for sale into this state. The effect of amending the rule is protection of the state's economic and environmental well-being from an extremely invasive, nonnative pest. No small businesses are likely to experience negative economic effects from this action, as none are known to offer kudzu for sale at this time. The rule would constitute a net benefit to the economy of the state by protecting its environment from a pest that is extremely costly to control or eradicate.

RCW 34.05.328 does not apply to this rule adoption. The Washington State Department of Agriculture is not a listed agency.

Hearing Location: Natural Resources Building, 1111 Washington Street, 2nd Floor, Conference Room 259, Olympia, WA 98504, on May 23, 2002, at 9:00 a.m.
