Cal. Food & Agr. Code § 6027.5
During the calendar year, each commissioner shall pay to the secretary a fee not to exceed fifty cents ($0.50) per pound of vertebrate pest control material sold, distributed, or applied by the county for vertebrate pest control purposes, less the amount necessary to recover the cost of complying with the provisions of this article, as determined by the secretary. No assessment shall be imposed on the sale or on the distribution of vertebrate pest control material by a county agricultural commissioner to another commissioner. Vertebrate pest control material registered by the secretary may only be sold or distributed by a county agricultural commissioner or as authorized by the secretary.
The secretary may set a different level of assessment in the amount necessary to provide revenue for the vertebrate pest control research projects carried out pursuant to this article only if the secretary, at a minimum, has consulted with the Vertebrate Pest Control Research Advisory Committee. The new level of assessment may only commence at the beginning of the subsequent calendar year. However, the assessment shall not exceed one dollar ($1) per pound of vertebrate control material sold, distributed, or applied by the county for vertebrate pest control purposes. To assist the advisory committee in making its recommendations, the department shall submit a progress report to the members of the advisory committee at least 30 days prior to each meeting of the advisory committee. The report shall include, but is not limited to, data on research that has been, or is proposed to be, conducted and statements regarding the necessity for that research. This section does not preclude the department from preparing and distributing additional reports that may be requested by the advisory committee.
