PROPOSED RULES

DEPARTMENT OF AGRICULTURE


[ Filed October 19, 2005, 11:16 a.m. ]

Original Notice.

Preproposal statement of inquiry was filed as WSR 04-19-060.

Title of Rule and Other Identifying Information: The department is proposing to establish a crucifer seed quarantine in Washington state by adding new rule sections to chapter 16-301 WAC, General seed regulations. The new sections are in response to a petition that the department received from the Puget Sound Seed Growers Association. They have been developed with the help of an ad hoc work group representing the industry and higher education research institutions. The petition also asked the department to amend WAC 16-301-050 to add black mustard (Brassica nigra) and wild radish (Raphanus raphanistrum) to the list of restricted noxious weed seeds and to delete the words "in rapeseed only" from the black mustard and wild radish reference in WAC 16-301-105 Seed certification -- Objectionable weeds, and the department is proposing amendments to comply with the request.

Hearing Location(s): WSU Extension Auditorium, 16650 State Route 536, Mt. Vernon, WA 98273, on Tuesday, December 6, 2005, at 10:00 a.m.; at the Washington State Department of Agriculture Office, 821 East Broadway, Suite #4, Moses Lake, WA 98837, on Friday, December 9, 2005, at 11:00 a.m.

Date of Intended Adoption: December 21, 2005.

Submit Written Comments to: Debbie Hacker, Department of Agriculture, P.O. Box 42560, Olympia, WA 98504-2560, e-mail dhacker@agr.wa.gov, fax (360) 902-2085, by 5:00 p.m., November 10, 2005.

Assistance for Persons with Disabilities: Contact Virginia Walsh by December 1, 2005, TTY (360) 902-1976.

Purpose of the Proposal and Its Anticipated Effects, Including Any Changes in Existing Rules: The purpose of this proposal is to address issues raised by the vegetable seed producers of western Washington regarding the increased planting of nonvegetable crucifer crops that have not been tested and found free of two specific diseases, black rot and black leg. If these diseases become established in their western Washington production area, they would severely threaten the existence of vegetable seed production. In addition, the nonvegetable crucifer crops often contain dormant seed that may persist into subsequent cropping years and become established as weeds. This proposal places a quarantine order on all seed planted in the regulated areas of western Washington and requires that all seed be tested and found free of the regulated diseases before planting. The proposal also places restrictions on the content of dormant seed where appropriate. Finally, this proposal places two weeds on the restricted noxious weed list. These weeds are wild radish and black mustard. These contaminates are prevalent in nonvegetable crucifer crops. By placing these weeds on the restricted noxious weed list they will be listed on the label of seed offered for sale, thus informing the buyer of their presence.

Reasons Supporting Proposal: This proposal will ensure that all crucifer seed is tested before planting in the regulated area thus protecting a vital segment of Washington agriculture. Washington is a major world exporter of crucifer vegetable seeds. By increasing protection against the introduction of these diseases, export markets will remain open for Washington products. In addition, this proposal will also protect the emerging production of oil seed for bio-diesel by requiring disease free seed stock. The Puget Sound Seed Growers Association, the Columbia Basin Seed Growers Association, the Washington Canola Commission and individual seed growers and seed companies support this proposal.

Statutory Authority for Adoption: Chapters 15.49 and 34.05 RCW.

Statute Being Implemented: Chapter 15.49 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: Victor Shaul, Yakima, Washington, (509) 225-2682; Implementation and Enforcement: Fawad Shah, Yakima, Washington, (509) 225-2636.

No small business economic impact statement has been prepared under chapter 19.85 RCW. RCW 19.85.030 (1)(a) requires an agency to prepare a small business economic impact statement (SBEIS) for proposed rules that impose a more than minor cost on the businesses in an industry. To determine if the costs imposed by the proposed crucifer quarantine were "more than minor," the department, with the help of industry and academic representatives, developed a list of 189 stakeholders that might be affected by the proposed quarantine. An economic impact survey was then mailed to each of the 189 stakeholders giving them two weeks to respond. In the past, the department has had very good response rates to the economic impact surveys that it has conducted. When responses to the crucifer quarantine survey were not received, the department telephoned each stakeholder on the mailing list and reminded them of the importance of completing the survey. Only two stakeholders responded to the survey (both past the two-week deadline) and neither was affected by the proposed quarantine. As a result, the department sent the survey by e-mail to twenty-five representative stakeholders on the original list. Again, the department received no responses. Based upon the expressed support, as well as input, that the department has received from the Puget Sound Seed Growers Association, the Columbia Basin Seed Growers Association, the Washington Canola Commission and individual seed growers and seed companies during the meetings of the crucifer working group and the apparent lack of interest in the economic impact survey, the department has concluded that the crucifer seed industry does not consider the costs imposed by the proposed quarantine to be "more than minor" and, therefore, has not prepared a formal SBEIS.

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).

OTS-8207.4

CRUCIFER SEED QUARANTINE
NEW SECTION
WAC 16-301-490   Why is the department establishing a crucifer seed quarantine?   The production of crucifer vegetable seed is an important industry in Washington state. The economic well-being of that industry is threatened by the introduction of crucifer seed infected with certain bacterial and fungal pathogens. In addition, certain crucifer species produce dormant seed that, if present in a seed lot will persist into subsequent cropping years. The resulting "volunteer" plants have the potential to become established as weeds in Washington state.

The director has determined that a quarantine is needed to protect the Washington crucifer vegetable seed industry from the introduction of seed infected with certain pathogens and from the introduction of crucifer seed containing dormant seed. The quarantine will provide the seed growers in this state with sources of crucifer seed that have been tested and proven to be free from harmful pathogens and, when appropriate, dormant seed.
