On September 12, 1996, the EPA published the Group IV Polymers and Resins NESHAP (61 FR 48208). This action temporarily extends the compliance date specified in 40 CFR 63.1311(c) for the provisions contained in 40 CFR 63.1329 for existing affected sources producing poly(ethylene terephthalate) (PET) using the continuous terephthalic acid (TPA) high viscosity multiple end finisher process because the EPA is in the process of responding to a request to reconsider relevant portions of the rule (Docket Item: A-92-45; VI-A-1). The EPA is providing this temporary extension to February 27, 2001 to complete reconsideration and any necessary revision to the rule. The EPA is providing this temporary extension pursuant to Clean Air Act section 301(a)(1).
