Group I Polymers and Resins: National Emission Standards for Hazardous Air Pollutants (NESHAP)

Rule Summary

In the production of elastomers, a variety of organic hazardous air pollutants (HAP) are used as monomers or process solvents: Styrene, n-hexane, 1,3-butadiene, acrylonitrile, methyl chloride, hydrogen chloride, carbon tetrachloride, chloroprene, and toluene. Some of these pollutants are considered to be mutagens and carcinogens, and all can cause reversible or irreversible toxic effects following exposure.

See the regulations below for more details.
