40 CFR Parts 60 and 63

[AD-FRL-6338-3]
RIN 2060-AH47


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published on March 9, 1999 (64 FR 11542), is withdrawn as of May 7, 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.

Assistant Administrator for Air and Radiation.
