WSR 05-21-029



[ Filed October 11, 2005, 8:06 a.m. , effective October 11, 2005 ]

Purpose: This rule-making order amends WAC 16-752-505 Wetland and aquatic weed quarantine -- Regulated articles, by adding Glyceria maxima to the list of aquatic plants prohibited from sale in Washington state.

Citation of Existing Rules Affected by this Order: Amending WAC 16-752-505.

Statutory Authority for Adoption: Chapters 17.24 and 34.05 RCW.

Under RCW 34.05.350 the agency for good cause finds that immediate adoption, amendment, or repeal of a rule is necessary for the preservation of the public health, safety, or general welfare, and that observing the time requirements of notice and opportunity to comment upon adoption of a permanent rule would be contrary to the public interest.

Reasons for this Finding: The intrusion into this state of nonnative, invasive plant species is of grave and immediate concern. Glyceria maxima, an aquatic weed, has been identified in two ponds in Snohomish County. It requires early intervention to successfully eradicate, as it is known as a very aggressive colonizer of freshwater environments. The biological window of opportunity to eliminate this infestation before anticipated seed set is very brief and does not allow time to complete the permanent rule-making process. This rule is being adopted to protect the economic well-being of the nursery industry, and the environmental quality and natural resources of the state.
