(1) The department, in consultation with the invasive species council, may classify or reclassify and list by rule nonnative aquatic animal species as prohibited level 1, level 2, or level 3, based on the degree of invasive risk, the type of management action required, and resources available to conduct the management action.
(a) Species classified as prohibited level 1 pose a high invasive risk and are a priority for prevention and expedited rapid response management actions.
(b) Species classified as prohibited level 2 pose a high invasive risk and are a priority for long-term infested site management actions.
(c) Species classified as prohibited level 3 pose a moderate to high invasive risk and may be appropriate for prevention, rapid response, or other prohibited species management plan actions by the department, another agency, a local government, tribes, or the public.
(2) The department, in consultation with the invasive species council, may classify and list by rule regulated type A species. This classification is used for nonnative aquatic animal species that pose a low to moderate invasive risk that can be managed based on intended use or geographic scope of introduction, have a beneficial use, and are a priority for department-led or department-approved management of the species' beneficial use and invasive risks.
(3) Nonnative aquatic animal species not classified as prohibited level 1, level 2, or level 3 under subsection (1) of this section, or as regulated type A species under subsection (2) of this section, are automatically managed statewide as regulated type B species or regulated type C species and do not require listing by rule.
(a) Species managed as regulated type B pose a low or unknown invasive risk and are possessed for personal or commercial purposes, such as for aquariums, live food markets, or as nondomesticated pets.
(b) Species managed as regulated type C pose a low or unknown invasive risk and include all other species that do not meet the criteria for management as a regulated type B invasive species.
(4) Classification of prohibited and regulated species:
(a) May be by individual species or larger taxonomic groups up to the family name;
(b) Must align, as practical and appropriate, with regional and national classification levels;
(c) Must be statewide unless otherwise designated by a water body, property, or other geographic region or area; and
(d) May define general possession and introduction conditions acceptable under department authorization, a permit, or as otherwise provided by rule.
(5) Prior to or at the time of classifying species by rule as prohibited or regulated under subsections (1) and (2) of this section, the department, in consultation with the invasive species council, must adopt rules establishing standards for determining invasive risk levels and criteria for determining beneficial use that take into consideration environmental impacts, and especially effects on the preservation of native species, salmon recovery, and threatened or endangered species.
