N2 - The Tennessee Valley Authority in cooperation with the state of Tennessee operated a continuous fine particle (PM2.5) monitor at a rural site to establish background PM2.5 air quality. Although this monitor usually measures levels substantially less than its more urban counterparts, it recorded unusually elevated PM2.5 levels from September 5-15, 2005. TVA and Tennessee conducted a case study analysis of this unusual event/episode considering the relationship between PM25 levels and various meteorological variables and potential local, regional and long range emissions sources. It is suspected that early morning inversions and stagnant conditions throughout the day associated with a high pressure system hindered the transport and dilution of PM2.5 levels caused by emissions from local agricultural burning, as well as long range transport of smoke from fires occurring in Idaho during the first half of the period. One concern of this episode is how a few elevated PM2.5 levels occurring in a relatively short time period influence the annual average for the site. The recently revised US PM2.5 daily standard (24-hr average of 35 micrograms per cubic meter) also means that episodes like this will take on even more importance in determining compliance. To better characterize local sources, TVA and Tennessee conducted additional monitoring - including filter based sampling - during 2006.
