California Code, Health and Safety Code - HSC § 43203

(a) In connection with surveillance of emissions from new motor vehicles prior to their retail sale, the state board may, by regulation, impose fees on manufacturers of these vehicles to recover the state board's costs in conducting this surveillance.

(b) A manufacturer who fails to pay a fee imposed pursuant to this section within 60 days after receiving an invoice shall pay the state board an additional fee equal to 10 percent of the fee specified in subdivision (a). If the manufacturer notifies the state board, within 60 days after receiving the invoice, that additional information is needed to honor the invoice, the state board shall grant an additional 90 days for payment without the imposition of an additional fee. An additional interest fee equal to the rate of interest earned by the Pooled Money Investment Fund shall be imposed upon the fee specified in subdivision (a) and the additional fees specified in this subdivision and subdivision (c) for each 30-day period for which they remain unpaid, commencing 60 days after the receipt of the original invoice.

(c) A manufacturer who fails to pay all the fees imposed pursuant to this section within one year from the date of receipt of the original invoice shall pay a penalty fee equal to 100 percent of the fees imposed pursuant to subdivisions (a) and (b). A manufacturer who fails to pay all the fees and penalties imposed pursuant to this section within two years from the date of receipt of the original invoice shall pay a penalty equal to 100 percent of the fees and penalties imposed pursuant to subdivisions (a) and (b) and to this subdivision, for each one-year period for which they remain unpaid.

(d) Fees authorized by this section shall be imposed only for surveillance of emissions from new motor vehicles actually conducted.

(e) Notwithstanding Section 13340 of the Government Code, all fees collected pursuant to subdivision (a) are continuously appropriated to the state board, to be credited as a reimbursement of the board's costs incurred in its program for the surveillance of emissions from new vehicles. All fees collected pursuant to subdivisions (b) and (c) shall be deposited by the state board into the Air Pollution Control Fund.
