Title: NESHAP for Plastic Parts and Products Surface Coating (Renewal). mstockstill on DSKH9S0YB1PROD with NOTICES SUPPLEMENTARY INFORMATION: VerDate Nov<24>2008 16:51 Mar 31, 2010 Jkt 220001 ICR Numbers: EPA ICR Number 2044.04, OMB Control Number 2060– 0537. ICR Status: This ICR is scheduled to expire on April 30, 2010. Under OMB regulations, the Agency may continue to conduct or sponsor the collection of information while this submission is pending at OMB. An Agency may not conduct or sponsor, and a person is not required to respond to, a collection of information unless it displays a currently valid OMB control number. The OMB control numbers for EPA’s regulations in title 40 of the CFR, after appearing in the Federal Register when approved, are listed in 40 CFR part 9, and displayed either by publication in the Federal Register or by other appropriate means, such as on the related collection instrument or form, if applicable. The display of OMB control numbers in certain EPA regulations is consolidated in 40 CFR part 9. Abstract: Entities potentially affected by this action are the owners or operators of plastic parts and products surface coating facilities. The affected entities are subject to the General Provisions of the NESHAP at 40 CFR part 63, subpart A, and any changes, or additions to the Provisions specified at 40 CFR part 63, subpart PPPP. Owners or operators of the affected facilities must submit a one-time-only report of any physical or operational changes, initial performance tests, and periodic reports and results. Owners or operators 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. Reports, at a minimum, are required semiannually. Burden Statement: The annual public reporting and recordkeeping burden for this collection of information is estimated to average 91 hours per response. Burden means the total time, effort, or financial resources expended by persons to generate, maintain, retain, or disclose or provide information to or for a Federal agency. This includes the time needed to review instructions; develop, acquire, install, and utilize technology and systems for the purposes of collecting, validating, and verifying information, processing and maintaining information, and disclosing and providing information; adjust the existing ways to comply with any previously applicable instructions and requirements which have subsequently changed; train personnel to be able to respond to a collection of information; search data sources; complete and review the collection of information; PO 00000 Frm 00038 Fmt 4703 Sfmt 4703 16459 and transmit or otherwise disclose the information. Respondents/Affected Entities: Plastic parts and products surface coating facilities. Estimated Number of Respondents: 828. Frequency of Response: Initially, occasionally, and semiannually. Estimated Total Annual Hour Burden: 320,917. Estimated Total Annual Cost: $27,444,633, which includes $27,180,233 in labor costs, $16,000 in capital/startup costs, and $248,400 in operation and maintenance (O&M) costs. Changes in the Estimates: There is a small decrease in the total estimated burden currently identified in the OMB Inventory of Approved ICR Burdens. This change in burden from the most recently approved ICR is due to an adjustment. Minor calculation errors in the previous ICR were corrected. Dated: March 22, 2010.

The EPA will consider comments received from the CASAC and the public in preparing revisions to this document. A second draft Policy Assessment document will be issued later this spring for CASAC and public review. The EPA will consider CASAC and public comments on the second draft Policy Assessment in preparing a final Policy Assessment. The final Policy Assessment will serve to ‘‘bridge the gap’’ between the scientific information and the judgments required of the Administrator in determining whether it is appropriate to retain or revise the current PM NAAQS. The first draft Policy Assessment does not represent and should not be construed to represent any final EPA policy, viewpoint, or determination. The EPA will consider any public comments submitted in response to this notice when revising this document. Dated: March 25, 2010.

Following denial of the petition for reconsideration, NJDEP filed a petition for review of that denial (No. 08–4818) and the two petitions were consolidated into one action. On July 23, 2009, NJDEP filed an administrative petition asking the Administrator to reopen the title V permit for the RRI Energy Portland plant pursuant to 40 CFR 70.7(f)(iii) & (iv).

page number).
     Follow directions--The agency may ask you to respond to 
specific questions or organize comments by referencing a Code of 
Federal Regulations (CFR) part or section number.
     Explain why you agree or disagree; suggest alternatives 
and substitute language for your requested changes.
     Describe any assumptions and provide any technical 
information and/or data that you used.
     If you estimate potential costs or burdens, explain how 
you arrived at your estimate in sufficient detail to allow for it to be 
reproduced.
     Provide specific examples to illustrate your concerns, and 
suggest alternatives.

SUPPLEMENTARY INFORMATION:  Under section 108(a) of the Clean Air Act 
(CAA), the Administrator identifies and lists certain pollutants which 
``cause or contribute to air pollution which may reasonably be 
anticipated to endanger public health or welfare.'' The EPA then issues 
air quality criteria for these listed pollutants, which are commonly 
referred to as ``criteria pollutants.'' The air quality criteria are to 
``accurately reflect the latest scientific knowledge useful in 
indicating the kind and extent of all identifiable effects on public 
health or welfare which may be expected from the presence of [a] 
pollutant in the ambient air, in varying quantities.'' Under section 
109 of the CAA, EPA establishes primary (health-based) and secondary 
(welfare-based) national ambient air quality standards (NAAQS) for 
pollutants for which air quality criteria are issued. Section 109(d) of 
the CAA requires periodic review and, if appropriate, revision of 
existing air quality criteria. The revised air quality criteria reflect 
advances in scientific knowledge on the effects of the pollutant on 
public health or welfare. The EPA is also required to periodically 
review and, if appropriate, revise the NAAQS based on the revised air 
quality criteria.
    As part of the ongoing review of the NAAQS for particulate matter 
(PM), EPA released a draft document titled Policy Assessment for the 
Review of the Particulate Matter National Ambient Air Quality 
Standards--First External Review Draft (March 2010, EPA 452/P-10-003) 
for review by the Clean Air Scientific Advisory Committee (CASAC) and 
public comment (75 FR 4067; January 26, 2010). The first draft Policy

recommendations from the CASAC by means of a review of the first draft 
Policy Assessment at an upcoming public teleconference of the CASAC 
that will be held on April 8-9, 2010 (75 FR 8062; February 23, 2010). 
The EPA will consider comments received from the CASAC and the public 
in preparing revisions to this document. A second draft Policy 
Assessment document will be issued later this spring for CASAC and 
public review. The EPA will consider CASAC and public comments on the 
second draft Policy Assessment in preparing a final Policy Assessment. 
The final Policy Assessment will serve to ``bridge the gap'' between 
the scientific information and the judgments required of the 
Administrator in determining whether it is appropriate to retain or 
revise the current PM NAAQS.
