Amendment of the existing wetland and aquatic weed quarantine rule was requested by the Washington State Noxious Weed Control Board.
Aquatic weeds can be extremely invasive and have an economically significant impact.
The quarantine of additional aquatic weeds is intended to prevent the introduction of these species in this state. However, the federal list is mainly intended to apply to international shipment, and the federal agency is not usually active in interstate or intrastate noxious weed regulation. The state office of USDA will be notified. The Washington State Noxious Weed Control Board establishes the state noxious weed list under authority of RCW 17.10 . It requested this change in Washington State Department of Agriculture quarantine to complement its own and the county noxious weed boards' efforts.
