Notice of Department Rulemaking: Invasive Mussels (Amend Sections 650, 672, 672.1, and 672.2, Title 14, California Code of Regulations (CCR))
July 3, 2026
The California Department of Fish and Wildlife (Department) has published the Notice of Proposed Action to amend sections 650, 672, 672.1, and 672.2 to Title 14, California Code of Regulations (CCR).
Fish and Game Code Section 2301 authorizes the Department to adopt regulations regarding the management of invasive mussels.
The Department proposes to amend sections 650, 672, 672.1, and 672.2 to Title 14 of the California Code of Regulations. Amendments include management measures for watercraft removed from invasive mussel infested waters, such as mandating the inspection of watercraft that have been launched in infested water for four or more consecutive nights. Additionally, the proposed changes establish a departmental list of conveyance service providers that adhere to industry standards for inspection and decontamination. This is necessary to expand the scope of the existing regulations to encompass all invasive mussel species, thereby ensuring consistency with the revised Fish and Game Code (FGC) established by Assembly Bill 149. The proposed amendments are intended to align regulations with current conditions and to incorporate a proactive component that addresses potential invasive mussel threats not presently identified within the California or the United States.
In accordance with the Administrative Procedure Act, the Department provided notice of the proposed regulatory action with the Office of Administrative Law for publication in the California Regulatory Notice Register on July 3, 2026.
