PERMANENT RULES
Effective Date of Rule: Thirty-one days after filing.
Purpose: The rule-making order amends chapters 16-301 and 16-302 WAC by modifying the scientific names of noxious weed seeds in order to update and reconcile the names with current nomenclature as listed in the USDA germplasm resource information network (GRIN). This will reduce confusion as to which seeds are considered noxious and will help to ensure that weed seeds are categorized correctly for seed shipments into Washington.
Citation of Existing Rules Affected by this Order: Amending WAC 16-301-045, 16-301-050, 16-302-100, and 16-302-105.
