National Emission Standards for Hazardous Air Pollutant Emissions: Group IV Polymers and Resins

The EPA is issuing this final rule amendment to indefinitely stay the current compliance date of February 27, 2001, for the provisions pertaining to process contact cooling towers (PCCT) for existing affected sources producing poly (ethylene terephthalate) (PET) using the continuous terephthalic acid (TPA) high viscosity multiple end finisher process. On August 29, 2000, the EPA issued a direct final rule (65 FR 52319) and a parallel proposal (65 FR 52392) to stay the compliance date indefinitely because the EPA is in the process of responding to a request to reconsider relevant portions of the rule which may result in changes to the emission limitation applying to PCCT in this subcategory. On September 20, 2000, the EPA received an adverse comment on the direct final rule for an indefinite stay of compliance. Therefore, the EPA withdrew the direct final rule (65 FR 64161; October 26, 2000). After considering the comments received, the EPA is promulgating the indefinite stay of compliance through this amendment.
