Original Notice.
Preproposal statement of inquiry was filed as WSR 14-05-093.
Title of Rule and Other Identifying Information: Chapter 16-462 WAC, Grape planting stockRegistration and certification, the agency is proposing to adopt changes to better align with the model grapevine standard of the National Clean Plant Network (NCPN) as a result of a petition submitted by the Washington Association of Wine Grape Growers. These changes include:
(1) Defining certification levels;
(2) Adding grapevine virus A, grapevine red blotch virus, grapevine vein clearing virus, and Xylella fastidiosa as regulated pests;
(3) Repealing the required testing for nematodes of the genus Longidorus prior to planting registered vines; and
(4) Improving language clarity.
Hearing Location(s): Washington State Department of Agriculture, 21 North First Avenue, Pest Program Conference Room, 1st Floor, Yakima, WA 98902, on September 23, 2014, at 11:00 a.m.
Date of Intended Adoption: October 7, 2014.
Submit Written Comments to: Henri Gonzales, P.O. Box 42560, Olympia, WA 98504-2560, e-mail, fax (360) 902-2094, by September 23, 2014.
Assistance for Persons with Disabilities: Contact Henri Gonzales by September 16, 2014, TTY (800) 833-6388 or 711.
Purpose of the Proposal and Its Anticipated Effects, Including Any Changes in Existing Rules: The agency is proposing to amend chapter 16-462 WAC, the grapevine certification rule, to align with the model grapevine standard of NCPN. It would also add grapevine virus A, grapevine red blotch virus, grapevine vein clearing virus, and Xylella fastidiosa as regulated pests. Following the NCPN model gives growers a clearer understanding of certification requirements.
Reasons Supporting Proposal: NCPN was created to protect specialty crops from the spread of economically harmful plant pests and diseases. Their mission is to provide healthy planting stock that is easier to propagate, requires fewer chemical inputs, and produces higher crop yields and better crop quality. This is done through programs which screen plant selections for viruses and other diseases that can be spread by contaminated planting stock.
Washington's grapevine certification program is a voluntary program that was first adopted in 1968 for the purpose of providing the grape growers a source of planting stock free of harmful pathogens. The rule has been revised several times since then to address new threats and the changing needs of a rapidly evolving grape industry. Modifying our certification program is necessary to continue to reduce the chance of introduction of exotic pests that can be difficult and costly to control and to further standardize our program with the NCPN model.
Statutory Authority for Adoption: RCW 15.14.015 and chapter 34.05 RCW.
Statute Being Implemented: RCW 15.14.015.
Rule is not necessitated by federal law, federal or state court decision.
Name of Proponent: Washington Association of Wine Grape Growers, private.
Name of Agency Personnel Responsible for Drafting, 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. This proposal imposes no additional regulations or costs on Washington businesses.
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).
