Addition of Natural Gas Processing Facilities to the Toxics Release Inventory (TRI)

EPA is proposing to add natural gas processing (NGP) facilities (also known as natural gas liquid extraction facilities) to the scope of the industrial sectors covered by the reporting requirements of section 313 of the Emergency Planning and Community Right-to-Know Act (EPCRA), commonly known as the Toxics Release Inventory (TRI) and section 6607 of the Pollution Prevention Act (PPA). Adding these facilities would meaningfully increase the information available to the public on releases and other waste management of listed chemicals from the natural gas processing sector and further the purposes of EPCRA section 313. EPA estimates that at least 282 NGP facilities in the U.S. would meet the TRI employee threshold (10 full- time employees or equivalent) and manufacture, process, or otherwise use (threshold activities) at least one TRI-listed chemical in excess of applicable threshold quantities. NGP facilities in the U.S. manufacture, process, or otherwise use more than 21 different TRI- listed chemicals, including n-hexane, hydrogen sulfide, toluene, benzene, xylene, and methanol. EPA expects that TRI reporting by U.S. NGP facilities would provide significant release and waste management data on these chemicals to the public.
