National Emission Standards for Hazardous Air Pollutants Emissions: Group I Polymers and Resins and Group IV Polymers and Resins and Standards of Performance for Volatile Organic Compound (VOC) Emissions from the Polymer Manufacturing Industry

On September 5, 1996, the EPA issued the National Emission Standards for Hazardous Air Pollutants (NESHAP) for Group I Polymers and Resins (61 FR 46906); on September 12, 1996, the EPA issued the Group IV Polymers and Resins NESHAP (61 FR 48208); and on December 11, 1990, the EPA issued the Standards of Performance for Volatile Organic Compound (VOC) Emissions from the Polymer Manufacturing Industry (55 FR 51035). This action revises the promulgated rules by adding provisions, correcting errors, and making clarifications in all of the above- mentioned rulemakings, as described in the remainder of this document.
