Rule Summary

These final standards implement section 112(d) of the Clean Air Act (CAA) which requires the Administrator to regulate emissions of hazardous air pollutants (HAP) listed in section 112(b) of the CAA. The intent of the standards is to protect the public by requiring new and existing major sources to control emissions to the level attainable by implementing the maximum achievable control technology (MACT).

Sources typically emit the following HAP: glycol ethers, methylene diphenyl diisocyanate, methyl ethyl ketone, toluene, and xylene. These compounds account for over 80 percent of the nationwide HAP emissions from this source category. These pollutants can cause reversible or irreversible toxic effects to people following exposure.
