LOS ANGELES (AP) — In an effort to ease congestion at the nation’s busiest port complex, officials say they will start fining shipping companies whose cargo containers linger for too long at marine terminals. The twin ports of Los Angeles and Long Beach say arriving containers scheduled to be moved by trucks will be allowed to stay for nine days before fines start accruing. Containers set to move by rail can stay at the ports for three days. After that, ocean carriers will be charged $100 per container, increasing in $100 increments per container per day. The new rules will go into effect Nov. 1.
