EPA issued a final rule on December 14, 2016, (81 FR 90207), that determined that the Houston-Galveston-Brazoria, Texas nonattainment area (HGB area) failed to attain the 2008 8-hour ozone national ambient air quality standard (NAAQS) by the applicable attainment deadline of July 20, 2016, and thus was classified by operation of law as "Moderate". In that action, EPA also determined January 1, 2017 as the deadline by which Texas must submit to the EPA the State Implementation Plan (SIP) revisions that meet the Clean Air Act (CAA) statutory and regulatory requirements that apply to 2008 ozone NAAQS nonattainment areas reclassified as Moderate. The language in the December 14, 2016 Federal Register amended the table in 40 CFR 81.344 (Subpart C-Section 107 Attainment Status Designations) titled "Texas--2008 8-Hour Ozone NAAQS (Primary and secondary)". The amendatory language failed to update the table for the classification date for HGB nonattainment area to 12/14/2016. This document corrects the listed classification date in the December 14, 2016 final rule document.
