San Pedro Bay Ports Clean Air Action Plan is a cooperative regulatory and operational framework between the Port of Los Angeles and the Port of Long Beach to reduce air pollutant and greenhouse gas emissions from port-related activities. The Plan integrates measures affecting shipping, cargo handling, rail, trucking, and waterfront operations and coordinates with state and federal agencies including the California Air Resources Board and the United States Environmental Protection Agency. It has evolved through multiple updates since the initial 2006 adoption, interacting with regional entities such as the South Coast Air Quality Management District and national programs like the Diesel Emissions Reduction Act.

Background and Purpose

The initiative originated amid community concerns in San Pedro, Los Angeles and Long Beach, California about diesel particulate matter and ozone precursors linked to international trade through the Ports of Los Angeles and Long Beach. Major stakeholders included the International Longshore and Warehouse Union, Pacific Maritime Association, and environmental organizations such as the Natural Resources Defense Council and the Environmental Defense Fund. The Plan’s purpose aligns with statutory mandates under the Clean Air Act and state law frameworks administered by the California Air Resources Board and complements regional planning by the South Coast Air Quality Management District. Early drivers included public health research from institutions like the University of Southern California and community activism in neighborhoods near the ports.

Key Components and Regulations

The Plan establishes regulatory and voluntary programs addressing vessel, cargo-handling equipment, locomotive, and truck emissions, coordinating with federal rules from the United States Coast Guard and the United States Maritime Administration. It includes shore power requirements for berthed vessels, low-sulfur fuel mandates consistent with International Maritime Organization sulfur limits, and truck replacement incentives parallel to programs under the California Air Resources Board's Truck and Bus Regulation (California). The Plan also integrates diesel retrofit and replacement grant structures that mirror funding mechanisms from the Federal Transit Administration and the Diesel Emissions Reduction Act, while aligning with local ordinances from Los Angeles City Council and policy instruments used by the Port of Long Beach Board of Harbor Commissioners.

Emission Reduction Measures and Technologies

Measures emphasize electrification, fuel switching, and cleaner engine technologies: ship shore power connections compatible with International Electrotechnical Commission standards, deployment of near-zero and zero-emission drayage trucks consistent with California Air Resources Board pathways, and replacement of cargo-handling equipment with electric or alternative-fuel models marketed by manufacturers such as Caterpillar Inc. and Kalmar/Cargotec. Locomotive controls draw on technology demonstrations by BNSF Railway and Union Pacific Railroad for idle-reduction and Tier 4 engines regulated under the United States Environmental Protection Agency’s emission standards. Ports incentivize use of low-sulfur marine fuels in line with the International Maritime Organization's MARPOL amendments and encourage adoption of liquefied natural gas and biofuel trials undertaken in cooperation with shipping lines like Maersk and Hapag-Lloyd.

Implementation and Compliance

Implementation is managed through joint governance by the Governance Committee (Port of Los Angeles and Port of Long Beach), permitting processes administered by the Port of Los Angeles Harbor Department and the Port of Long Beach Harbor Department, and enforcement coordination with the South Coast Air Quality Management District and the California Air Resources Board. Compliance mechanisms include procurement policies, lease requirements, conditional use permits, and financial incentive programs funded by federal grants from the Environmental Protection Agency and state programs administered through the California Energy Commission. Legal oversight has involved litigation and settlement processes in state courts and federal district courts, occasionally invoking agencies such as the United States Department of Justice.

Monitoring, Reporting, and Health Impacts

Monitoring strategies combine ambient air monitoring networks operated with support from the South Coast Air Quality Management District and emission inventories developed using models from the University of California, Riverside and California Air Resources Board. Reporting requirements feed into statewide inventories like the California Greenhouse Gas Inventory and federal emissions tracking referenced by the National Emissions Inventory maintained by the United States Environmental Protection Agency. Health impact assessments have referenced epidemiological studies from the University of Southern California Keck School of Medicine, California Department of Public Health, and peer-reviewed literature in journals such as Environmental Health Perspectives to quantify reductions in diesel particulate matter, nitrogen oxides, and related hospital admission metrics in nearby communities like San Pedro and Wilmington.

Outcomes, Results, and Criticism

Reported outcomes include substantial reductions in diesel particulate emissions and nitrogen oxides since the Plan’s inception, documented in progress reports by the Port of Los Angeles and Port of Long Beach and evaluated by independent reviewers from institutions such as the RAND Corporation and the National Academy of Sciences. The Plan has been credited with accelerating adoption of shore power and near-zero truck fleets in California and influencing national port policy dialogues involving the United States Conference of Mayors and the Harbor Maintenance Trust Fund stakeholders. Criticism centers on implementation pace, cost burdens on small owner-operators represented by the Independent Drivers Guild and the Teamsters, perceived gaps in greenhouse gas accounting relative to AB 32 targets, and calls from environmental justice advocates including Communities for a Better Environment for stronger community investments and tighter timelines. Ongoing debates involve balancing trade competitiveness, supply chain resilience interests voiced by the National Retail Federation and American Association of Port Authorities, and ambitious decarbonization commitments advocated by groups like C40 Cities and the International Maritime Organization.
