Organic Liquids Distribution: National Emission Standards for Hazardous Air Pollutants (NESHAP)
These national emission standards for hazardous air pollutants (NESHAP) are for new and existing organic liquids distribution (OLD) (non-gasoline) operations, which are carried out at storage terminals, refineries, crude oil pipeline stations, and various manufacturing facilities. The EPA estimates that approximately 5,300 megagrams per year (Mg/ yr) (5,900 tons per year (tpy)) of HAP are emitted from facilities in this source category. Although a large number of organic HAP are emitted nationwide from these operations, benzene, ethylbenzene, toluene, vinyl chloride, and xylenes are among the most prevalent.
These HAP have been shown to have a variety of carcinogenic and noncancer adverse health effects. The EPA estimates that the final standards will result in the reduction of HAP emissions from major sources with OLD operations by 60 percent.
