The EPA is finalizing permanent exemptions from the title V operating permit program for five categories of nonmajor (area) sources that are subject to national emission standards for hazardous air pollutants (NESHAP). The EPA is making a finding for these categories, consistent with the Clean Air Act requirement for making such exemptions, that compliance with title V permitting requirements is impracticable, infeasible, or unnecessarily burdensome on the source categories. The five source categories are dry cleaners, halogenated solvent degreasers, chrome electroplaters, ethylene oxide (EO) sterilizers and secondary aluminum smelters. The EPA declines to make a finding for a sixth category, area sources subject to the NESHAP for secondary lead smelters. A previous deferral from permitting for this category expired on December 9, 2004, subjecting all such sources to the title V program.
