** In May 2008, the Port of Los Angeles implemented a special study to collect "real-time" PAH data at four air quality monitoring stations located in or near the Port. This study was funded under a grant administered by the Environmental Protection Agency. The data collection for the study is complete and a comprehensive report which details the findings of this special study is available.

for your information. Real-time PAH data will not be reported after December 31, 2010.
