Upgrades theft of a catalytic converter to one crime degree higher than the underlying theft offense would otherwise warrant based on value

Restricts the sale of detached used catalytic converters to scrap metal businesses only, unless the seller is a registered business that regularly deals in catalytic converters or motor vehicle parts

Requires scrap metal businesses to verify seller identity and refuse purchases from sellers who do not provide the required documentation
