What does the fugitive emissions rule regulate?

The fugitive emissions rule specifically targets unintentional emissions that escape from equipment, facilities, or processes and are not captured or controlled by standard emission control systems. This includes emissions that might leak from valves, pumps, flanges, and other interfaces in industrial settings, as well as those released during routine operations or maintenance. These emissions can contribute to air pollution and are often more challenging to monitor and control compared to those that are intentionally regulated through conventional methods.

This focus on unintentional emissions is crucial because these sources can significantly impact overall air quality and compliance with environmental regulations. By regulating these emissions, authorities aim to reduce air pollutants that may not be addressed by other regulations, ensuring a more comprehensive approach to managing air quality. The other options highlight aspects of emissions that are either regulated differently or do not fall under the purview of fugitive emissions regulations, which emphasizes the importance of addressing the specific nature of fugitive emissions in environmental policy.
