The Fairbanks North Star Borough has issued a Stage 3 air quality alert for North Pole, valid until noon on Friday.

“This alert has been implemented due to PM2.5 concentrations that have exceeded the 12 hour threshold of 55µg/m3. As of 12 p.m. today, the 12 hour average is 104µg/m3,” a statement from FNSB Mayor’s Office said.

The alert prohibits “new fuel sources” from being added to solid fuel-burning appliances, including “masonry heaters, pellet fuel burning appliances, cook stoves, fireplaces, or waste oil burning appliances,” according to the Mayor’s Office. Fuel sources already burning are allowed until the fire has died out.

“Residents should rely instead on their home’s alternate, cleaner source of heat (such as a furnace, boiler or electric baseboard heaters) until the Stage 3 air alert is cancelled,” the mayor’s statement read.

Recreational fires — bonfires, campfires, ceremonial fires and fire pits — are permitted, but all other outdoor burning is prohibited until the alert ends.

The Mayor’s Office encouraged anyone with questions regarding the alert to contact the FNSB Air Quality Division by calling 459-1005, or emailing
