Halogenated Solvent Cleaning: National Emission Standards for Hazardous Air Pollutants (NESHAP)

On this page:

Rule Summary

The halogenated solvent cleaner National Emission Standards for Hazardous Air Pollutants (NESHAP) requires batch vapor solvent cleaning machines and inline solvent cleaning machines to meet emission standards reflecting the application of the maximum achievable control technology (MACT) for major and area sources. Area source batch cold cleaning machines are required to achieve generally available control technology. The rule regulates the emissions of the following halogenated hazardous air pollutants (HAP) solvents: methylene chloride (MC), perchloroethylene (PCE), trichloroethylene (TCE), 1,1,1- trichloroethane (TCA), carbon tetrachloride (CT), and chloroform (C).
