Southern California air regulators proposed tougher rules Friday to ensure that the ports of Los Angeles and Long Beach reduce their share of deadly emissions from ships, trains, big rigs and cargo-handling equipment, prompting harsh objections from harbor officials.

Geraldine Knatz, executive director of the Port of Los Angeles, said, “We don’t think we need a backstop rule and we are not willing to support financial penalties. They want us to impose fines on our customers and that is not something we are willing do in the middle of an economic downturn.”
