NESHAP for Group IV Polymers and Resins (40 CFR part 63, subpart JJJ) (Renewal)

The National Emission Standards for Hazardous Air Pollutants (NESHAP) for Group IV Polymers and Resins (40 CFR Part 63, Subpart JJJ) were proposed on March 29, 1995; promulgated on September 12, 1996; and most-recently amended on March 27, 2014. These regulations apply to each new and existing thermoplastic product process units (TPPU) and associated equipment that produce the subset of polymers and resins known as Group IV Polymers and Resins that is a major source of organic hazardous air pollutants (HAPs). Group IV polymers and resins include the following source categories: Acrylonitrile Butadiene Styrene (ABS), Methyl Methacrylate Acrylonitrile Butadiene Styrene (MABS), Methyl Methacrylate Butadiene Styrene (MABS), Nitrile Resin, Polyethylene Terephthalate (PET), Polystyrene (PS), and Styrene Acrylonitrile (SAN). The following processes are excluded from this rule: research and development facilities; polymerization processes occurring in a mold; processes which manufacture binder systems containing thermoplastic product for paints, coatings, or adhesives; finishing processes including equipment such as compounding units, spinning units, drawing units, extruding units, and other finishing steps; and solid state polymerization processes. New facilities include those that commenced construction or reconstruction after the date of proposal and meets the new source definitions at 63.1310(i). This information is being collected to assure compliance with 40 CFR Part 63, Subpart JJJ. In general, all NESHAP standards require initial notifications, performance tests, and periodic reports by the owners/operators of the affected facilities. They are also required to maintain records of the occurrence and duration of any startup, shutdown, or malfunction in the operation of an affected facility, or any period during which the monitoring system is inoperative. These notifications, reports, and records are essential in determining compliance, and are required of all affected facilities subject to NESHAP.
