CA SB1087

Prohibits any person from purchasing used catalytic converters except from specific authorized sellers: automobile dismantlers, licensed core recyclers with fixed business locations, motor vehicle dealers, automotive repair dealers, other licensed businesses that generate catalytic converters, or individuals with documentation proving lawful ownership of the converter.

Makes it an infraction punishable by fines to purchase used catalytic converters from unauthorized sources: $1,000 for first offense, $2,000 for second offense, and $4,000 for third or subsequent offense.

Requires core recyclers purchasing catalytic converters to maintain detailed records including seller identification, vehicle identification numbers, photographs, written statements about converter origin, and proof of lawful ownership; allows exemptions for written agreements with established businesses.

Changes payment methods for catalytic converter sales from checks only to any traceable form of payment except cash, with delayed payment requirements for individuals but immediate payment allowed for businesses.

Expands existing misdemeanor penalties for core recyclers violating record-keeping requirements, with fines up to $4,000 and possible business closure for repeat violations.
