Ports Cleaning Up by Reducing Emissions

IMET DPF installedNew Air Monitoring Data Shows Lowest Levesl of Diesel Exhaust Around Port of Los Angeles Since Collection of Data Began.   PoLA and the Port of Long Beach have aggressively pursued significant reduction in emissions from mobile sources for the last decade.   In 2006 the Ports initiated the Clean Air Action Plan that established monitoring stations, included funding the Technology Advancement Program (TAP) and stimulated the development of the Clean Truck Program.  The efforts continue as the Port of LA recently released the preliminary results from adoption of the internationally recognized Environmental Ship Index (ESI) Program.

For calendar year 2012, elemental carbon was down by 72 percent in Wilmington compared to calendar year 2006, which was the first full year of monitoring data collected. The San Pedro monitoring station also showed a significant decrease of 61 percent. These drops in elemental carbon happened even as cargo volumes at the Port have rebounded – in 2012 the Port handled 1.7 percent more cargo than in 2011, but elemental carbon at both the Wilmington monitoring and San Pedro stations were 39 and 18 percent lower, respectively, than in 2011.

Most of the attention to date has focused on trucks, tractors and the various large diesel powered equipment that move containers and cargo around after unloading.  In the near future the Ports will direct more attention to completely eliminating emissions while ships tie up at dockside for loading or unloading by using shore power rather than ship’s diesel generators.  And in addition to lower polluting fuels and re-routing marine traffic to reduce emission impacts, large Ocean Going Vessels have been installing advanced emission control equipment thereby reducing pollution while in transit.
