Determination of Nonattainment and Reclassification of the Houston-Galveston-Brazoria 2008 8-Hour Ozone Nonattainment Area; Texas

摘要

The Environmental Protection Agency (EPA) is proposing to determine that the Houston-Galveston-Brazoria ozone nonattainment area (HGB area) failed to attain the 2008 8hour ozone national ambient air quality standards (NAAQS) by the applicable attainment deadline of July 20, 2016, and thus is classified by operation of law as "Moderate". In this action, EPA is also proposing January 1, 2017 as the deadline by which Texas must submit to the EPA the State Implementation Plan (SIP) revisions that meet the CAA statutory and regulatory requirements that apply to 2008 ozone NAAQS nonattainment areas reclassified as Moderate.
