Re: 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 ofthe HGB 2008 Eight-Hour Ozone 

Standard Attainment Date 

Dear Mr. Curry: 

The Texas Commission on Environmental Quality (TCEQ) requests that the United States 

Environmental Protection Agency (EPA) issue a determination of attainment, also known as a clean 

data determination, of the 1997 eight-hour ozone National Ambient Air Quality Standard (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 ofthe 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 eighthour ozone NAAQS for 2012 through 2014. The HGB area monitored attainment of the standard with 

an So 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 February 24, 2015. 

The TCEQ also requests 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 state 

implementation plan revision to the EPA on July 16, 2014. 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/ i\321) in 2014.
