Surface Coating of Automobiles and Light-Duty Trucks: National Emission Standards for Hazardous Air Pollutants (NESHAP)

Rule Summary

This action promulgates national emission standards for hazardous air pollutants (NESHAP) for automobile and light-duty truck surface coating operations located at major sources of hazardous air pollutants (HAP). The final rule implements section 112(d) of the Clean Air Act (CAA) by requiring these operations to meet HAP emission standards reflecting the application of the maximum achievable control technology (MACT). The primary HAP emitted by these operations are toluene, xylene, glycol ethers, methyl isobutyl ketone (MIBK), ethylbenzene, and methanol.  

The final rule will decrease HAP emissions from automobile and light duty truck surface coating facilities from an estimated 10,000 tons per year (tpy) to 4,000 tpy. Emissions of the HAP methyl ethyl ketone (MEK) are included in the emissions inventory and emission reduction estimates for this source category. MEK has been delisted since promulgation of the final rule. Volatile organic compounds also are emitted by these operations. The final rule will decrease VOC emissions by approximately 12,000 tpy to 18,000 tpy.
