AB 2032: Fish and wildlife: invasive mussels: golden mussels.

Official summary

Legislative Counsel’s Digest (official, as of the latest version). Written by nonpartisan legislative staff; reproduced verbatim.

(1)Existing law, until January 1, 2030, generally prohibits a person from possessing, importing, shipping, or transporting in the state, or from placing, planting, or causing to be placed or planted in any water within the state, invasive mussels, as defined. Existing law requires a public or private agency that operates a water supply system to cooperate with the Department of Fish and Wildlife (department) to implement measures to avoid infestation by invasive mussels and to control or eradicate any infestation that may occur in a water supply system, and, if invasive mussels are detected, to prepare and implement a plan, as specified, to control or eradicate invasive mussels within the system (control plan).

Existing law prohibits the importation, transportation, possession, or live release of specified wild animals, except under a revocable, nontransferable permit, known as a restricted species permit, issued by the department, in cooperation with the Department of Food and Agriculture, and only if certain requirements are met.

This bill would exempt from the requirement to obtain a restricted species permit for invasive mussels a public or private agency that operates a water supply system and has submitted a control plan to the department for maintenance, operational, and research activities within the water supply system, as specified. The bill would exempt from the requirement to obtain a restricted species permit for dead invasive mussels a public or private agency that operates a water supply system and has submitted a control plan to the department for research, outreach, education, species verification, training, or other purposes deemed by the department to be in the best interest of the state. The bill would provide that these exemptions remain in effect for a particular public or private agency until the department determines the agency’s control plan does not meet the statutory requirements for control plans or approves the control plan.

This bill would require the department’s Invasive Species Program to develop, by April 1, 2027, voluntary guidance for public and private agencies that operate water supply systems to develop effective control plans. The bill would also require the department’s Invasive Species Program to develop and publish, by April 1, 2027, guidance for scientific research conducted by or for public and private agencies that operate water supply systems to prevent and control the spread of invasive mussels, as specified.

This bill would require the department to update the spatial distribution maps of invasive mussel-infested water bodies posted on its internet website no less than quarterly based on monitoring and reported detections, as prescribed.

(2)Existing law requires every manufacturer of, importer of, or dealer in any pesticide, except as specified, to obtain a certificate of registration from the Department of Pesticide Regulation before the pesticide is offered for sale. Existing law requires the Director of Pesticide Regulation to endeavor to eliminate from use in the state specified pesticides, and in carrying out this responsibility, to develop an orderly program for the continuous evaluation of all pesticides actually registered, as specified.
