CA AB3151

Changes "ocean marine terminal" to "port terminal" (including ocean marine terminals or other terminals within a port master plan area) and requires intermodal roadability inspection programs instead of merely authorizing them.

Removes eligibility requirements that terminals have more than 1,000 chassis based there and prior satisfactory compliance ratings from terminal inspections.

Expands inspection requirements to include container connecting devices, mud flaps, and frame damage; adds verification that state 90-day Basic Inspection of Terminals and Federal Motor Carrier Safety Administration annual inspections are current.

Requires defects noted on intermodal chassis to be repaired within 10 days after inspection and before the chassis is released from the terminal, with violation constituting a misdemeanor; extends record retention from 90 days to 6 months.

Expands anti-retaliation protections to cover port terminal operators, independent equipment providers, trucking companies, and other respondeat superior entities; requires departments to conduct 30-day interval inspections until full compliance is achieved after failed reinspections.
