I. Background On February 22, 2021, the EPA
published its proposal to approve parts of the Fairbanks Serious Plan and associated SIP revisions 86 FR 10511.
Specifically, we proposed to approve the submitted revisions to the Alaska SIP as meeting the base year emissions inventory and precursor demonstration requirements triggered for the Fairbanks PM2.5 Nonattainment Area upon reclassification of the area to Serious on May 10, 2017 82 FR 21711. The EPA
also proposed to approve as SIPstrengthening the submitted sections of the Alaska Air Quality Control Plan for the Fairbanks PM2.5 Nonattainment Area, state effective January 8, 2020, related to the Emergency Episode Plan.
The EPA also proposed to approve and incorporate by reference as SIPstrengthening the submitted regulatory changes to Alaska Administrative Code Title 18, Environmental Conservation, Chapter 50, Air Quality Control 18
AAC 50. The reasons for our proposed approval are described in the EPAs February 22, 2021, proposal and will not be restated here 86 FR 10511.
II. Public Comments and EPA
Responses The EPA provided a 30-day period for the public to comment on the proposed action that ended on March 24, 2021.
We received 19 public comments. The public comments can be found in the docket for this action. Each of the 19
comments raise concerns about a suite of measures Alaska included under 18
AAC 50.077 that prohibit the installation, reinstallation, sale, lease, distribution, or conveyance of woodfired heating devices in the Fairbanks PM2.5 Nonattainment Area.
Comment 1: The Hearth, Patio &
Barbecue Association HPBA, Blaze King Industries, Inc., Hearth & Home Technologies, Inc., Jotul, Kozy Heat Fireplaces, Kuma Stoves, Inc., Woodstock Soapstone Company, Myren Consulting, Inc., Rais, Fireplace Products International Ltd. FPI, Travis Industries, United States Stove Company, and two anonymous commenters raise concerns about the States submitted revisions to heating device requirements established in regulation at 18 AAC 50.077. The current SIP-approved heating device requirements in this rule place restrictions on wood-fired hydronic heaters and wood-fired heating devices with a manufacturer-rated heat output

capacity of less than 350,000 British Thermal Units BTUs per hour and prohibit the installation, reinstallation, sale, lease, distribution, or conveyance of a woodstove in the area, unless:
The EPA has certified the device under 40 CFR 60.533; and an EPA-accredited lab has tested the woodstove and determined it meets an emissions limit of 2.5 grams per hour, and the test results were obtained using EPA New Source Performance Standard NSPS for new residential wood heaters test procedures 40 CFR part 60, appendix A, Methods 28, 28A, and 28R, or alternative cordwood methods that have been approved by the EPA, and the test results were obtained using EPA NSPS emissions concentration measurement procedures 40 CFR part 60, appendix A, Methods 5G and 5H.
The submitted SIP revisions tighten the applicable woodstove emissions limit from 2.5 grams/hour to 2.0 grams/
hour, require that alternative methods used to test a woodstove be approved by both the EPA and the Alaska Department of Environmental Conservation ADEC, and specify that during testing, a woodstove must not emit more than 4 grams/hour or 6
grams/hour depending on the test methods and measurement procedures used. Specifically, the submissions revise the regulation at 18 AAC 50.077
to prohibit the installation, reinstallation, sale, lease, distribution, or conveyance of a woodstove in the area, unless: 1
The EPA has certified the device under 40 CFR 60.533, and an EPA-accredited lab has tested the woodstove and determined it meets an emission limit of 2.0 grams per hour, and the test results were obtained using EPA NSPS test procedures Methods 28, 28A, or 28R, or alternative test methods, including broadly applicable test methods, if approved by both EPA
and the Alaska Department of Environmental Conservation; and the test results were obtained using EPA NSPS emission concentration measurement procedures Methods 5G
and 5H; and After September 1, 2020, the test results must demonstrate: 1 No rolling 1 Other components of 18 AAC 50.077 were largely retained, such as the requirements for woodstoves and pellet stoves under 18 AAC
50.077c applying to devices with a manufacturerrated heat output capacity of less than 350,000 Btu per hour, and that the EPA certification should be calculated in grams per hour and approved by the department with supporting data.
