Following its Clean Air Act (CAA) residual risk and technology review (RTR) of its 1995 National Emissions Standards for Hazardous Air Pollutants (NESHAP) covering aerospace manufacturing and rework facilities, the EPA is amending NESHAP by establishing requirements for specialty coating operations, which were not previously subject to NESHAP.

The amendments establish organic hazardous air pollutant (HAP) and volatile organic compound (VOC) content limits for 57 specialty coating categories and also require specialty coating operations to meet the same inorganic HAP control requirements applicable to primers and topcoats.
According to the EPA, about 144 facilities are subject to the aerospace NESHAP.
