Approval and Promulgation of Air Quality Implementation Plans; Texas; Revision To Control Volatile Organic Compound Emissions in the Houston/Galveston/Brazoria 8-Hour Ozone Nonattainment Area

The Environmental Protection Agency (EPA) is approving a revision to the Texas State Implementation Plan (SIP). The revision adds additional requirements to control volatile organic compound (VOC) emissions from storage tanks, transport vessels and marine vessels in the Houston/Galveston/Brazoria (HGB) 1997 8-hour ozone nonattainment area, which consists of Brazoria, Chambers, Fort Bend, Galveston, Harris, Liberty, Montgomery and Waller counties. Specifically, this revision subjects owners or operators of VOC storage tanks, transport vessels, and marine vessels located in the HGB 1997 8-hour ozone nonattainment area to more stringent control, monitoring, and recordkeeping requirements. EPA is approving the SIP revision because it will help lower ozone levels in the HGB area by reducing VOC emissions. EPA is approving the revision pursuant to section 110 and part D of the Clean Air Act (CAA).
