Polyether Polyols Production: National Emission Standards for Hazardous Air Pollutants (NESHAP)
On this page:
Polyether polyols are used in making lubricants, adhesives, sealants, cosmetics, soaps, and feedstock polymers for urethanes production. Air toxics can be emitted at several points along the manufacturing process.
The hazardous air pollutants (HAP) emitted by the facilities producing polyether polyols include ethylene oxide (EO), propylene oxide (PO), hexane, toluene, and incidental emissions of several other HAP. Some of these pollutants are considered to be probable human carcinogens when inhaled, and all can cause toxic effects following exposure.
The rule is estimated to reduce emissions of these pollutants by 1,810 Megagrams per year (Mg/yr) (2,000 tons per year (tons/yr)).
See the regulations below for more details.
