Existing law requires a core recycler that accepts, ships, or sells used catalytic converters to maintain specified information regarding the purchase and sale of the catalytic converters. Existing law prohibits a core recycler from providing payment for a catalytic converter unless, among other requirements, the payment is made by check, as specified. This bill, in addition to payment by check, would allow for payment by credit card or any other form of traceable payment other than cash. Existing law licenses and regulates motor vehicle dealers and retailers. Existing law prohibits a motor vehicle dealer or retailer from selling any motor vehicle that is not in compliance with the requirements enumerated in the Vehicle Code. This bill would prohibit a dealer or retailer from selling a new or used motor vehicle equipped with a catalytic converter unless the catalytic converter has been permanently marked, as defined, with the vehicle identification number of the vehicle to which it is attached. The bill would, until January 1, 2025, exempt from this prohibition a vehicle purchased from a dealer licensed in this state who is also licensed in another state and does not have a warranty service facility in this state. A violation of this provision would be punishable as an infraction, as specified. By creating a new infraction, this bill would impose a state-mandated local program. The California Constitution requires the state to reimburse local agencies and school districts for certain costs mandated by the state. Statutory provisions establish procedures for making that reimbursement. This bill would provide that no reimbursement is required by this act for a specified reason.
