Rule Description
- 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.
