ILTA filed comments September 24 with the U.S. Environmental Protection Agency in support of EPA’s action that will allow a major source to reclassify to an area source at any time by limiting its potential to emit (PTE) hazardous air pollutants (HAP) to below the major-source thresholds. As EPA has explained in the notice, the Clean Air Act (CAA) does not require that a source remain a major HAP source once designated as such. This action will potentially incentivize source operators of major HAP facilities to reduce their HAP PTE and thereby allow them to reclassify to an area source and reduce their regulatory burden.
