Health & Saf. Code, § 25553

(a) (1) Each county may, upon a majority vote of the governing body, adopt a schedule of fees to be collected from businesses which request the services provided by this chapter. The fee schedule shall be developed by the county in consultation with local business representatives. The fee shall be set in an amount sufficient to pay only those costs incurred by the county in carrying out this chapter. In determining the fee schedule, the administering agency shall consider the volume and degree of hazard potential of the hazardous materials handled by the business.

(2) A county may seek supplemental funds for the support of activities carried out pursuant to this chapter from existing state funds which are available to local governmental entities for the costs of waste control and enforcement programs, to the extent that use of the funds will alleviate the disposal of hazardous wastes in solid waste landfills.

(b) A county which has established a hazardous materials information and consulting service pursuant to this chapter shall provide these services to an individual business which has not been assessed a fee as determined by the schedule adopted pursuant to subdivision (a). A business provided services pursuant to this subdivision shall pay a fee to the county for these services at a rate set by the county.
