Solid Fuel-fired Heating Device Standards

The solid fuel-fired heating device standards in 18 AAC 50.077 and 18 AAC 50.079 apply to devices installed or supplied, sold, leased, distributed, or conveyed for installation or operation inside the Fairbanks North Star Borough PM2.5 Nonattainment Area only. Beginning February 28, 2015 for hydronic heaters and large heating devices, August 31, 2015 for woodstoves and pellet stoves, and January 12, 2018 for coal heaters, it will be unlawful to install a heating device that does not meet the emission standards or requirements. Retailers may still sell noncompliant devices to customers who verify in writing that they intend to install the device outside the area.

Property Sale, Lease, or Conveyance - Changeout or Removal Requirement

The Environmental Protection Agency (EPA) has redesignated the PM2.5 Nonattainment Area from 'moderate' to 'serious.' EPA proposed the redesignation on May 10, 2017. See: Federal Register Notice (PDF).

18 AAC 50.077 requires the change-out or removal of wood-fired heating devices not meeting emission criteria when the property where they are installed is sold, leased, or conveyed. - Effective June 9, 2017 -

18 AAC 50.079 requires the change-out or removal of coal-fired heating devices that are not EPA certified or listed with the Fairbanks North Star Borough when the property, where they are installed, is sold, leased, or conveyed - Effective January 12, 2018 -
