**SUPPLEMENTARY INFORMATION:**
**Notice of Final Action**
On November 14, 2025, the EPA issued a final decision to issue a permit, Permit No. C-2025-6, to Lupton Plant Property, LLC, a limited liability corporation incorporated in Idaho with its principal place of business in Idaho Falls, Idaho, and Lupton Petroleum Products Inc., a general business corporation incorporated in Idaho with its principal place of business in Idaho Falls, Idaho. This permit pertains to the modification and operation of the Lupton Facility (“Source”), an existing transmix processing and bulk petroleum storage facility, located partially on Navajo Nation Reservation in Lupton, Arizona. The EPA issued the permit pursuant to the provisions of CAA sections 110(a) and 301(d) and the EPA's Tribal Minor NSR Program at 40 CFR 49.151-49.164. The EPA based its decision on its determination that the Source met the applicability criteria and submitted all required content in the permit application under the EPA's Tribal Minor NSR Program. Notice of the final decision was provided on November 17, 2025, pursuant to 40 CFR 49.159(a). In accordance with 40 CFR 49.159(d)(1), permit decisions may be appealed under the permit appeal procedures of 40 CFR 124.19. In accordance with 40 CFR 124.19, within 30 days after service of notice of the final permit decision, any person who filed comments on the draft permit or participated in a public hearing on the draft permit may file a petition to the EPA's Environmental Appeal Board (EAB) for review. Additionally, any person who failed to file comments or failed to participate in the public hearing on the draft permit may petition the EAB for administrative review of any permit conditions set forth in the final permit decision, but only to the extent that those final permit conditions reflect changes from the proposed draft permit. The EPA received one comment filed on the draft permit during the public comment period. The EPA did not hold, or receive a request for, a public hearing on the draft permit. In the EPA's permit issued in its final permit decision, the EPA responded to public comments received but did not change the final permit conditions from those of the proposed draft permit. The EAB did not receive a petition to review any condition in the permit decision under 40 CFR 124.19. Therefore, pursuant to 40 CFR 49.159(a), this permit became effective on December 17, 2025.
