The Environmental Protection Agency (EPA) is proposing to determine that the Fairbanks North Star Borough nonattainment area failed to attain the 2006 24-hour fine particulate matter (PM<INF>2.5</INF>) National Ambient Air Quality Standards (NAAQS) by the December 31, 2019 "Serious" area attainment date. This proposed determination is based on complete, quality-assured and certified PM<INF>2.5</INF> monitoring data for 2017-2019. The EPA is also proposing to deny the State's request for an extension of the Serious area attainment date for the Fairbanks North Star Borough nonattainment area. Upon finalization of these determinations, the State will be subject to further statutory and regulatory requirements for this area, including a new State Implementation Plan (SIP) submission meeting additional requirements that the State must submit by December 31, 2020.
