Fairbanks - particulate matter (pm2.5)


A portion of the Fairbanks North Star Borough, including the City of Fairbanks and the City of North Pole, was designated as a PM2.5 nonattainment area in December 2009. These areas exceed the health based 24 hour PM2.5 National Ambirent Air Quality Standard (NAAQS) of 35 micrograms/cubic meter.

Analysis shows that local emissions from wood stoves, burning distillate oil, industrial sources, and mobile emissions contribute to particulate pollution. For planning purposes, PM2.5 is primarily a concern during the winter months (October through March) when extremely strong temperature inversions are frequent and human-caused air pollution impacts increase. Summertime wildland fire smoke is also a health concern, but is considered natural and uncontrollable.
