National Emission Standards for Hazardous Air Pollutants: Publicly Owned Treatment Works; Final Rule

Resumen

On October 26, 1999, we promulgated the national emission standards for hazardous air pollutants (NESHAP) for publicly owned treatment works (POTW). In this action, we are promulgating amendments which were proposed pursuant to a settlement agreement with the Pharmaceutical Research and Manufacturers of America (PhRMA) regarding their petition for judicial review of the POTW NESHAP. The amendments will rescind an applicability provision; adopt, for all industrial POTW treatment plants that are area sources of hazardous air pollutants (HAP), the same NESHAP requirements that apply to industrial POTW treatment plants that are major sources of HAP; and exempt industrial POTW treatment plants that are area sources of HAP from the permit requirements in section 502(a) of the Clean Air Act (CAA).
