Preproposal statement of inquiry was filed as WSR 04-10-111.
Title of Rule and Other Identifying Information: Chapter 16-752 WAC, Noxious weed control, this proposal adds several species, including: Crassula helmsii, Sagittaria platyphylla, Trapa bicornus, Polygonum cuspidatum, Polygonum polystachyum, Polygonum sachalinense, and Polygonum x bohemicum to the current quarantine. The proposal also rewrites WAC 16-752-500 to increase its clarity and readability.
Hearing Location(s): Washington State Department of Agriculture, 1111 Washington Street S.E., Natural Resources Building, 2nd Floor, Conference Room 205, Olympia, WA 98504-2560, on August 19, 2004, at 2:00 p.m.
Date of Intended Adoption: September 2, 2004.
Submit Written Comments to: Henri Gonzales, P.O. Box 42560, Olympia, WA 98504-2560, e-mail email@example.com, fax (360) 902-2094, by August 19, 2004.
Assistance for Persons with Disabilities: Contact Henri Gonzales by August 5, 2004, TTY (360) 902-1996.
Purpose of the Proposal and Its Anticipated Effects, Including Any Changes in Existing Rules: This proposal adds the following species to the current wetland and aquatic weed quarantine (WAC 16-752-505): Crassula helmsii (Australian swamp stonecrop), Sagittaria platyphylla (delta arrowhead), and Trapa bicornus (water caltrap, devil's pod, bat nut). In addition, this proposal adds the following species to the current noxious weed seed and plant quarantine (WAC 16-752-610): Polygonum cuspidatum (Japanese knotweed), Polygonum polystachyum (Himalayan knotweed), Polygonum sachalinense (giant knotweed), and Polygonum x bohemicum (Bohemian knotweed, a hybrid of Japanese and giant knotweed). The proposal also rewrites WAC 16-752-500 to increase its clarity and readability. 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. The Washington Noxious Weed Control Board, as authorized in chapter 17.10 RCW, supports this proposal.
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: Mary Toohey, 1111 Washington Street S.E., Olympia, WA 98504-2560, (360) 902-1907; Implementation and Enforcement: Tom Wessels, 1111 Washington Street S.E., 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. Analysis of the economic effects of the proposed rule amendments demonstrate that the changes will not be more than a minor cost on the regulated industry and, therefore, an SBEIS is not required. However, failure to adopt these changes may have a large impact on the regulated industry.
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).

AMENDATORY SECTION(Amending WSR 01-01-014, filed 12/6/00, effective 1/6/01)
WAC 16-752-500 Establishing wetland and aquatic weed quarantine. Washington waters and wetlands are threatened by nonnative, aggressive weeds that destroy the commercial, aesthetic, fish and/or wildlife habitat, and recreational value of these areas. ((
African elodea, Brazilian elodea (or
egeria), Eurasian watermilfoil, fanwort, slender-leaved naiad,
hydrilla and water chestnut (a different species from the food
"water chestnut" commonly sold in grocery stores) are
submersed, rooted species that can invade shallow to deep
water. Parrotfeather, water primrose, and yellow floating
heart are rooted plants that invade shallow water and aquatic
margins. European frogbit and swollen bladderwort are freely
floating species.)) These rooted or freely floating plant
species, when established, form dense stands or mats that
(( will)) clog irrigation systems and waterways, displace
native species, alter fish and wildlife habitat, and/or
seriously impact recreational use of the waterways.
Garden loosestrife, hairy willow herb, grass-leaved
arrowhead, mud mat, marsh dew flower and flowering rush are
rooted plants which invade wetlands, shallow water and aquatic
margins. When established, their dense stands displace native
vegetation and harm wildlife habitat.
Salt meadow)) Several species of Spartina, generally
known as cordgrasses, ((
common cordgrass, and smooth cordgrass
are noxious)) are nonnative, highly aggressive weeds that have
invaded salt water estuarine areas on the Washington coast,
displacing native species(( ,)) and threatening bird and mammal
habitats and the shellfish industry. (( Dense-flowered
cordgrass, a closely related species, has potential to
duplicate this invasion.))
The director of agriculture, pursuant to the powers provided in chapters 17.10, 15.13 and 17.24 RCW, finds that the regulation and exclusion of these plants and plant parts are necessary to preserve Washington waters and wetlands, both fresh water and estuarine, from new or additional infestation. These requirements and restrictions, contained in WAC 16-752-500 through 16-752-525, are in addition to the requirements contained in WAC 232-12-271, "Criteria for planting aquatic plants and releasing wildlife," administered by the Washington state department of fish and wildlife.
