Description of Rules
- Fugitive emissions can escape from seals around valves and moving rods, joints, and process drains. The emissions are described as fugitive because they are not captured by a vent.
- Finding and fixing fugitive emissions is also known as leak detection and repair, or LDAR.
- Apply to fugitive emissions from petroleum refineries in all the affected counties.
- Apply to fugitive emissions from petrochemical processes in the Beaumont–Port Arthur, Dallas–Fort Worth, El Paso, and Houston-Galveston-Brazoria areas.
- Include inspection, monitoring, and repair requirements using hydrocarbon analyzers or optical imaging devices.
- Include record-keeping requirements for affected sources.
The Chapter 115 rule history for fugitive emissions discusses revisions to the rules, including their proposal and adoption, the associated State Implementation Plan revision, and U.S. Environmental Protection Agency approval.
