Natural Gas Transmission and Storage Facilities: National Emission Standards for Hazardous Air Pollutants (NESHAP)
On this page:
The Environmental Protection Agency (EPA) issued final rules to reduce emissions of hazardous air pollutants (HAPs) from oil and natural gas production facilities as well as natural gas transmission and storage facilities. These rules implement section 112 of the Clean Air Act (CAA). Emissions from various processes and operations at oil and natural gas production facilities and natural gas transmission and storage facilities typically contain 5 different HAPs: benzene, toluene, ethyl benzene, and mixed xylenes, and n-hexane. HAPs, also known as air toxics, are pollutants which are known or suspected to cause cancer or other serious health effects such as birth defects or reproductive effects.
