Approval and Promulgation of Air Quality Implementation Plans; Texas; Rules for the Control of Highly Reactive Volatile Organic Compounds in the Houston/Galveston/Brazoria Ozone Nonattainment Area
EPA is approving rules adopted by the Texas Commission on Environmental Quality (TCEQ) for the control of highly reactive Volatile Organic Compounds (HRVOCs) in the Houston/Galveston/Brazoria (HGB) ozone nonattainment area. These rules for the control of HRVOCs supplement Texas' existing rules for controlling volatile organic compounds (VOC) by providing more extensive requirements for certain equipment in HRVOC service. These additional controls of HRVOC emissions will help to attain and maintain the national ambient air quality standards (NAAQS) for ozone in HGB.
