National Emission Standards for Hazardous Air Pollutant 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

AGENCY: Environmental Protection Agency (EPA).

ACTION: Withdrawal of amendment in direct final rule.

SUMMARY: Due to an adverse comment, the EPA is withdrawing an amendment from the March 9, 1999 direct final rule for the National Emission Standards for Hazardous Air Pollutants (NESHAP): 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 (64 FR 11536). This amendment deals with the oxygen correction factor requirements when complying with the 20 parts per million by volume (ppmv) control device outlet concentration compliance option for continuous front-end process vents. The withdrawal of the amendment from the direct final rule will only affect sources subject to the Group I Polymers and Resins NESHAP.

DATES: Amendment 6 in the direct final rule, which amends Sec. 63.485, published on March 9, 1999 (64 FR 11542), is withdrawn as of May 7, 1999. The remaining amendments will be effective May 10, 1999 as stated in the March 9 rule.

ADDRESSES: Docket No. A-92-44 containing supporting information used in the development of this notice is available for public inspection and copying between 8 a.m. and 5:30 p.m., Monday through Friday, excluding holidays. The docket is located in the EPA's Air and Radiation Docket and Information Center, Waterside Mall, Room M-1500, 401 M Street, SW, Washington, DC 20460, or by calling (202) 260-7548. A reasonable fee may be charged for copying docket materials.

SUPPLEMENTARY INFORMATION: On March 9, 1999, the EPA published a direct final rule (64 FR 11536) and a parallel proposal (64 FR 11555) to amend portions of the Group I and Group IV Polymers and Resins NESHAP. Also on March 9, 1999, the EPA published a notice (64 FR 11560) proposing amendments to the Group I and Group IV Polymers and Resins NESHAP (40 CFR part 63, subparts U and JJJ, respectively) to make changes to the 1996 promulgated rules, in response to technical issues raised through a 1996 petition for review.

The EPA stated in the direct final rule (64 FR 11536, March 9, 1999) that if relevant, adverse comments were received by April 8, 1999, the EPA would publish a notice to withdraw the affected portions of the direct final rule before its effective date of May 10, 1999. The EPA received an adverse comment on Amendment 6 in the direct final rule and, therefore, is withdrawing Amendment 6. This withdrawal of Amendment 6 only affects sources subject to the Group I Polymers and Resins NESHAP (40 CFR part 63, subpart U). Amendment 6 would have changed the requirements in Sec. 63.485(a) to reference a new paragraph (Sec. 63.485(v)), which would have adjusted the control device outlet concentration of 20 ppmv using a 3 percent oxygen correction factor.

The adverse comment stated that Sec. 63.485(a) in the direct final rule makes reference to paragraphs in separate proposed amendments (64 FR 11560, March 9, 1999), which respond to a 1996 petition for review, rather than to paragraphs in the 1996 promulgated NESHAP (40 CFR part 63, subpart U). The commenter said that Amendment 6 in the direct final rule caused confusion in interpreting the intent of the regulation. The EPA will address this comment on the withdrawn amendment in the subsequent final action on the proposed amendments. The 25 amendments for which we did not receive adverse comments will become effective on May 10, 1999, as provided in the March 9, 1999 direct final rule (64 FR 11536).

Dated: April 29, 1999. Robert Perciasepe, Assistant Administrator for Air and Radiation.
