Determination of Attainment; Texas; Houston-Galveston-Brazoria 1997 Ozone Nonattainment Area; Determination of Attainment of the 1997 Ozone Standard

The Environmental Protection Agency (EPA) has determined that the Houston-Galveston-Brazoria (HGB) 8-hour ozone nonattainment area is currently attaining the 1997 ozone National Ambient Air Quality Standard (NAAQS). This determination is based upon certified ambient air monitoring data that show the area has monitored attainment of the 1997 ozone NAAQS for the 2012-2014 monitoring period and continues to monitor attainment of the NAAQS based on preliminary 2015 data. Thus, the requirements for this area to submit an attainment demonstration, a reasonable further progress (RFP) plan, contingency measures, and other State Implementation Plan (SIP) documents related to attainment of the 1997 ozone NAAQS shall be suspended for so long as the area continues to attain the 1997 ozone NAAQS.
