Surface Coating of Metal Cans: National Emission Standards for Hazardous Air Pollutants (NESHAP)
On this page:
Rule Summary
The final standards implement section 112(d) of the Clean Air Act (CAA) by requiring metal can surface coating operations to meet Hazardous Air Pollutant (HAP) emission standards reflecting the application of the maximum achievable control technology (MACT). The final rule will protect air quality and promote public health by reducing emissions of HAP from facilities in the metal can surface coating source category. The HAP emitted by these facilities include glycol ethers, xylenes, hexane, and methyl isobutyl ketone (MIBK).
The final standards are expected to reduce nationwide HAP emissions by approximately 6,160 Mg/yr (6,800 tons per year (tpy)) or 70 percent from the baseline organic HAP emissions of 8,700 Mg/yr (9,600 tpy). Emissions of the HAP methyl ethyl ketone (MEK) and ethylene glycol monobutyl ether (EGBE) are included in the emission inventory and emission reduction estimates for this source category. Both HAP have been delisted since promulgation of the final rule.
