Controlling VOC Emissions from Degassing Storage Tanks, Transport Vessels, and Marine Vessels
- Beaumont–Port Arthur area (Hardin, Jefferson, and Orange counties)
- Dallas–Fort Worth area (rule only applies in Collin, Dallas, Denton, and Tarrant counties)
- El Paso area (El Paso County)
- Houston-Galveston-Brazoria area (Brazoria, Chambers, Fort Bend, Galveston, Harris, Liberty, Montgomery, and Waller counties)
- Control requirements reduce VOC emissions from the degassing of storage tanks, transport vessels, and marine vessels.
- Apply to degassing during, or in preparation of, the cleaning of any storage tank, transport vessel, or marine vessel containing any VOC with a true vapor pressure greater than 0.5 pounds per square inch absolute under actual storage conditions.
- These rules are a contingency measure in the El Paso area, so compliance is not currently required.
The Chapter 115 rule history for degassing of storage tanks, transport vessels, and marine vessels discusses revisions to the rules, including their proposal and adoption, the associated State Implementation Plan revision, and U.S. Environmental Protection Agency approval.
