PORT OF L.A.'s 2009 AIR EMISSIONS INVENTORY CONTINUES TO SHOW A DECREASING TREND IN PORT-RELATED AIR POLLUTION

Per-Unit Cargo Measure, Which Accounts for Recession-Related Cargo Declines, Shows 47 Percent Drop in Diesel Particulate (DPM) Emissions since 2005

SAN PEDRO, Calif. — June 3, 2010 — The just-released 2009 Inventory of Air Emissions associated with cargo handling operations at the Port of Los Angeles shows diesel particulate matter (DPM) emissions dropped by 37 percent from 2008, nitrogen oxide (NOx) emissions fell 28 percent, and sulfur oxide (SOx) emissions down by 36 percent.  When comparing 2009 emissions to 2005 emissions, the reductions are even more dramatic:  52 percent for DPM, 33 percent for NOx, and 56 percent for SOx. 

On an emissions per 10,000 Twenty-Foot Equivalent (20-foot containers or “TEU”) basis, which accounts for recession-related decreases in cargo volumes, the drop in emissions is also significant. Between 2005 and 2009, particulate matter emissions, including DPM, PM2.5 and PM10, dropped by 47 percent. NOx fell 26 percent and SOx dropped 51 percent in the same five-year period. In the last year alone, DPM, PM2.5 and PM10 each experienced a 26 to 27 percent drop using the per-unit-of-cargo measure. DPM is an identified toxic air contaminant and known carcinogen. NOx and SOx are key components of smog.

“We are extremely pleased to see how effective the Clean Air Action Plan has been,” said Port Executive Director Geraldine Knatz, Ph.D. “Even with recession-related cargo declines factored in, we saw very positive year over year emissions reductions in 2009. The results show that the investments the Port and its customers have made in cleaner operations are delivering a healthy pay-off.”

Pollutant emissions on a per-unit-of-cargo basis are a key target of the San Pedro Bay Ports Clean Air Action Plan (CAAP). When it adopted the CAAP in 2006, the Port pledged not only to reduce overall emissions but to make sure that each ton of cargo would be moved with fewer emissions in coming years. That way, even if cargo volumes continue to rise, total port-related air pollution should decline over time.

The Clean Air Action Plan’s goals for 2014 include cutting Port-related DPM emissions by 72 percent, NOx emissions by 22 percent, and SOx emissions by 93 percent below 2005 levels. Further decreases are targeted by 2023. The CAAP goals are closely tied into the South Coast Air Quality Management District’s plan to meet federal air quality standards.

“We’re definitely on track to meet the Clean Air Action Plan’s Bay-wide Standards – our long-term air quality goals,” said Christopher Patton, the Port’s Acting Assistant Director of Environmental Management. “In fact, in five years we’ve come more than halfway towards our ten-year target for DPM and SOx emissions reductions, and we are striving to continue to exceed our target for NOx. As we continue to apply the CAAP’s existing and new control measures, we expect the reduction trend to continue in 2010.”

The biggest emission declines in the 2009 calendar year can be attributed to the Clean Truck Program implemented in October 2008. Nationwide, truck sales slumped during 2009. Truck sales locally, however, increased significantly as local companies invested hundreds of millions of dollars in new trucks.

Patton also pointed to the state’s restrictions on the sulfur content of fuel (most recently for ocean-going vessels) as well as the Port’s Alternative Maritime Power and Vessel Speed Reduction programs as other important factors in the dramatic declines in emissions since the start of the CAAP.  In addition to substantial tenant and customer investments, the Port and its partner agencies have also spent millions of dollars replacing cargo handling equipment and harbor craft engines and/or retrofitting with pollution control devices in advance of statewide regulations, pioneering the use of alternative fuels and power systems, and assisting to modernize the Pacific Harbor Line switcher locomotive fleet. 

The emissions inventory, which has been conducted annually since 2005, uses actual records of activity by cargo handling equipment (ships, trucks, trains, cranes, and other yard equipment); data on the types and ages of the equipment; and up-to-date information on emissions factors for the various engines to calculate the actual amount of emissions produced by port activities over the year. These methods were developed in cooperation with the South Coast Air Quality Management District and the California Air Resources Board to ensure accuracy and consistency with the inventory techniques used by those agencies in other applications. The emissions inventory is one of the most important ways the Port measures progress toward CAAP goals.

An Air Quality Report Card, which compares emissions between 2005 and 2009, is now available online.

The Port of Los Angeles is America’s premier port and has a strong commitment to developing innovative strategic and sustainable operations that benefit the economy as well as the quality of life for the region and the nation it serves.  As the leading seaport in North America in terms of shipping container volume and cargo value, the Port generates 919,000 regional jobs and $39.1 billion in annual wages and tax revenues.  A proprietary department of the City of Los Angeles, the Port is self-supporting and does not receive taxpayer dollars.
