Aurora Energy, LLC
Chena Power Plant
The Alaska Department of Environmental Conservation (ADEC) has made a preliminary decision to approve Aurora Energy, LLC’s (Aurora’s) application for Air Quality Control Minor Permit AQ0315MSS02 Revision 1 for the Chena Power Plant.
Applicant: Aurora Energy, LLC
100 Cushman Street, Suite 210, Fairbanks, AK 99701
Location: Chena Power Plant
1206 1st Avenue, Fairbanks, AK 99701
Activity: The basis for this permit revision is classified under AS 46.14.130(c)(2), because the Department finds that public health or air quality effects provide a reasonable basis to regulate the stationary source. This finding is contained in the State Implementation Plan (SIP) for the Fairbanks North Star Borough (FNSB) Serious Nonattainment Area (NAA) adopted on November 19, 2019.
The Department is processing Minor Permit AQ0315MSS02 Revision 1 under the Department’s revoke and reissuance procedures under AS 46.14.280(a)(2), and therefore no permit application was submitted by the Permittee. The Department is preparing a new comprehensive SIP with a new determination that SO2 BACT limits for major stationary sources are not required to satisfy the State’s obligations under the Clean Air Act requirements for stationary sources in the NAA. Given that the Department originally issued Minor Permit AQ0315MSS02 for the sole purpose of implementing SO2 controls identified in the FNSB NAA SIP for the Chena Power Plant, The Department now finds no underlying basis for issuing such permit
The Department sent GVEA a notice of intent to revoke and reissue Minor Permit AQ0315MSS02 under AS 46.14.280(a)(2), on July 30, 2024, to remove SO2 conditions and add PM2.5 conditions and additional monitoring, recordkeeping, and reporting (MR&R) requirements.
Emissions: Minor Permit AQ0315MSS02 Revision 1 authorizes a change in SO2 emissions only. With this permitting action, the Chena Power Plant’s potential SO2 emissions will revert to 1,983.1 tons per year, the levels in place upon the issuance of AQ0315MSS02 before the existing SO2 limits went into effect on June 9, 2021. The Department does not consider this change to be a potential or actual emissions increase under 18 AAC 50.502(c)(3), or a potential or net emissions increase under 40 C.F.R. 52.21(b).
ADEC Preliminary Review: ADEC drafted a preliminary permit decision for this project under AS 46.14 and 18 AAC 50.
