(a)
Manufacturers of all motor vehicle models described in Section 44472 shall submit quarterly records and an annual report to the state board detailing the percentage of new models certified for sale, sold, or offered for sale in California with CFC-alternative mobile air-conditioning systems not using the CFC-based products enumerated in subdivision (a) of Section 44471. Compliance with Section 44472 shall be based on the total number of new motor vehicle models with non-CFC-based vehicle air-conditioners certified for sale, sold, or offered for sale versus the total number of new motor vehicle models with vehicle air-conditioners certified for sale, sold, or offered for sale in California each year.
(b)
Each of the deadlines set forth in Section 44472 may be extended for a period of not more than two years upon a determination by the state board that chemical or technological alternatives to CFC-based products are not yet available and in sufficient supply, or that manufacturers of new motor vehicles require additional time to redesign vehicle air-conditioning systems.
(c)
The state board shall adopt regulations by March 1, 1992, providing for the enforcement of this part.
