Oil and Natural Gas Sector: National Emission Standards for Hazardous Air Pollutants

Résumé

This action requests information related to hazardous air pollutant (HAP) emissions from sources in the oil and natural gas production and natural gas transmission and storage segments of the oil and natural gas sector. In 2012, the Environmental Protection Agency (EPA) revised the National Emission Standards for Hazardous Air Pollutants (NESHAP) for the Oil and Natural Gas Production Facilities and the Natural Gas Transmission and Storage Facilities major source categories. This action requests additional data and information that was not available at that time. In particular, we are requesting data on storage vessels without potential flash emissions (PFE) and data on HAP emissions from regulated small glycol dehydrators. With regard to the small glycol dehydrators we are particularly interested in data regarding any emissions of HAP other than benzene, toluene, ethylbenzene, and xylene (BTEX), information on available control options for any such HAP and information regarding a potential compliance demonstration issue with respect to the 2012 standards for small glycol dehydration units, as they apply to units with very low emissions.
