Request for Determination of Attainment of the 1997 Eight-Hour Ozone Standard for the Houston-Galveston-Brazoria (HGB) and Dallas-Fort Worth (DFW) Areas and Request for a One-Year Extension of the HGB 2008 Eight-Hour Ozone Standard Attainment Date

In a letter dated February 27, 2015, the TCEQ requested that the United States Environmental Protection Agency (EPA) issue a determination of attainment, also known as a clean data determination, for the 1997 eight-hour ozone NAAQS for the HGB and DFW nonattainment areas. Under 40 Code of Federal Regulations (CFR) §51.918 as well as proposed CFR §51.1118, an EPA determination that an area is attaining the 1997 eight-hour ozone NAAQS suspends certain state planning requirements related to attainment of the standard. This determination of attainment request is based on complete, quality-assured, certified ambient air monitoring data that show the HGB and the DFW areas have monitored attainment of the 1997 eight-hour ozone NAAQS for 2012 through 2014. The HGB area monitored attainment of the standard with an 80 parts per billion (ppb) design value and the DFW area with an 81 ppb design value. The 2014 Annual Data Certification was submitted to the EPA on February 27, 2015.

The TCEQ also requested a one-year attainment date extension to July 20, 2016 for the HGB 2008 eight-hour ozone NAAQS marginal nonattainment area in accordance with Federal Clean Air Act, §181(a)(5). The TCEQ certifies that the state has complied with all marginal requirements and commitments pertaining to the HGB area by submitting a base year emissions inventory SIP revision to the EPA on July 16, 2014. The EPA published direct final approval of this SIP revision in the February 20, 2015 Federal Register (80 FR 9204). The HGB area also meets the monitoring data requirement with a 72 ppb fourth highest daily eight-hour monitored average in the HGB 2008 ozone nonattainment area as measured at the Conroe Relocated monitor (C78/A321) in 2014.
