The North Pole Fire Station monitor is located on the west side of the North Pole Fire Station #3 [Bing Map: 3288 Hurst Road, North Pole, Alaska 99705], run by the FNSB North Star Volunteer Fire Department. The North Pole Fire Station monitor recorded the following:
- 48 days from October 1 to December 31 exceeded the health-based EPA PM 2.5 standard of 35 micrograms/cubic meter (µg/m3).
- 101.3 µg/m3 was the average exceedance concentration.
- 68% of the days from October 23 to the end of the year exceeded the standard (48 of 70 days)
- 184 µg/m3 was the highest daily average recorded.
- 353 µg/m3, an hourly reading, was recorded Thursday, December 20, 2012 at 1 am. Two higher hourly outliers were not graphed: 580 and 516. Clean Air Fairbanks excluded these because they seem too high to believe; however, they may be accurate.
- 59.9 µg/m3 was the average for the three-month period, Oct 1 to Dec 31, 2012.
The colors in the graph are based on EPA’s newly revised Air Quality Index.
