(2) For a CAIR NO x Ozone Season allowance allocation under section 96.341(b)(2), the allowances will be determined using the unit’s baseline heat input equal to the unit’s single highest adjusted control period heat input for the years that are five, six, seven and eight years before the first year of the control periods for which the CAIR NO x Ozone Season allowance allocation is being calculated. **Subpart FFFF -**  **“CAIR NO x**  **Ozone Season Allowance Tracking System”** The provisions of Title 40 CFR Part 96, subpart FFFF, as originally published in the Federal Register and as subsequently amended upon publication in the Federal Register as listed below, are incorporated by reference as if fully repeated herein. **40 CFR Part 96 subpart FFFF** Federal Register Citation Volume Date Notice Original Promulgation Vol. 70 May 12, 2005 [70 FR 25162] Revision Vol. 71 April 28, 2006 [71 FR 25304] Revision Vol. 71 December 13, 2006 [71 FR 74792] Section 96.353(c) is modified to read: By December 1, 2010 and December 1 of each fourth year thereafter, the Administrator will record in the CAIR NO
