SUPPLEMENTARY INFORMATION:
Throughout this document wherever we, us, or our is used, we mean the EPA.
I. Background Ground-level ozone is a gas that is formed by the reaction of Volatile Organic Compounds VOC and Oxides of Nitrogen NOX in the atmosphere in the presence of sunlight. These precursors VOC and NOX are emitted by many types of pollution sources, including point sources such as power plants and industrial emissions sources;
on-road and off-road mobile sources motor vehicles and engines; and smaller residential and commercial sources, such as dry cleaners, auto body shops, and household paints, collectively referred to as area sources.
Ozone is predominately a summertime air pollutant 83 FR 25777, June 4, 2018.
On October 1, 2015, we revised the ozone NAAQS to a level of 0.070 parts per million ppm annual fourthhighest daily maximum 8-hour average concentration, averaged over 3 years.
See 80 FR 65296, October 26, 2015; and 40 CFR 50, appendix U for more information on the revised 2015 ozone NAAQS, including a detailed explanation of the calculation of the 3year 8-hour average. The revised 2015
ozone NAAQS provide greater protection of public health and the environment than the previous ozone NAAQS of 0.075 ppm, set in 2008.
Although the 2015 ozone NAAQS retain the same general form and averaging time as the NAAQS set in 2008, the lower level is more protective.
The DFW and HGB areas were classified as Marginal ozone nonattainment areas for the 2015 ozone NAAQS with an attainment deadline of August 3, 2021 83 FR 25776, June 4, 2018. Bexar County which includes the City of San Antonio was also classified as a Marginal ozone nonattainment area with an attainment deadline of September 24, 2021 83 FR
35136, July 25, 2018. The DFW area consists of Collin, Dallas, Denton, Ellis, Johnson, Kaufman, Parker, Tarrant, and Wise Counties. The HGB area consists of Brazoria, Chambers, Fort Bend, Galveston, Harris, and Montgomery Counties.
On June 24, 2020, Texas submitted a SIP revision for the DFW, HGB and Bexar County areas. The SIP revision included a description of how provisions previously approved by EPA
meet the 2015 ozone NAAQS Marginal area CAA requirements for 1 NNSR
