Shipbuilding and Ship Repair (Surface Coating): National Emission Standards for Hazardous Air Pollutants (NESHAP)
On this page:
The national emission standards for hazardous air pollutants (NESHAP) requires existing and new major sources to control emissions using the maximum achievable control technology (MACT) to control hazardous air pollutants (HAP).
The standard is based on maximum HAP limits for various categories of marine coatings. Surface coating operations at shipyards are the focus of the NESHAP, and a variety of HAP are used as solvents in marine coatings. The HAP emitted by the facilities covered by this final rule include xylene, toluene, ethylbenzene, methyl isobutyl ketone, ethylene glycol, and glycol ethers. All of these pollutants can cause reversible or irreversible toxic effects following exposure. Emissions of the HAP MEK were included in the emissions inventory and emission reduction estimates for this source category. MEK has been delisted since promulgation of the final rule.
The final rule is estimated to reduce baseline emissions of HAP by 24 percent, or 350 tons per year (318.5 Mg/yr).
