Release of Draft Document Related to the Review of the National Ambient Air Quality Standards for Carbon Monoxide, 55843-55845 [E9-26093]

Download as PDF 55843 Federal Register / Vol. 74, No. 208 / Thursday, October 29, 2009 / Notices 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; and transmit or otherwise disclose the information. Respondents/Affected Entities: Entities potentially affected by this ICR include individuals or entities engaged in activities related to the registration of a pesticide product, which may be identified by the North American Industrial Classification System (NAICS) code 325320. Estimated Number of Respondents: 103. Frequency of Response: As needed. Estimated Total Annual Hour Burden: 178,285. Estimated Total Annual Cost: $14,103,722. This ICR does not involve any capital investment or maintenance and operational costs. Changes in the Estimates: There is a net decrease of 80,615 hours in the total estimated burden currently identified in the OMB Inventory of Approved ICR Burdens. EPA anticipates that 47 fewer tolerance petitions will be received annually compared to the previous three years (2006, 2007, and 2008). This would result in a corresponding 81,122 hour reduction in estimated annual burden. The change is an adjustment. In addition, EPA estimates that IR–4 petitioners are changing the way in which they compile tolerance petitions for submission to EPA in an effort to capture the new fee waiver incentives under the Pesticide Registration Improvement Renewal Act. This change in IR–4 petition preparation results in an additional 13 hours per response, resulting in a program change increase of 507 hours annually. Dated: October 23, 2009. Richard T. Westlund, Acting Director, Collection Strategies Division. [FR Doc.

A. What Should I Consider as I Prepare My Comments for EPA?

    1. Submitting CBI. Do not submit this information to EPA through 
https://www.regulations.gov or e-mail. Clearly mark the part or all of 
the information that you claim to be CBI. For CBI information in a disk 
or CD-ROM that you mail to EPA, mark the outside of the disk or CD-ROM 
as CBI and then identify electronically within the disk or CD-ROM the 
specific information that is claimed as CBI. In addition to one 
complete version of the comment that includes information claimed as

Information so marked will not be disclosed except in accordance with 
procedures set forth in 40 CFR part 2.
    2. Tips for Preparing Your Comments. When submitting comments, 
remember to:
     Identify the rulemaking by docket number and other 
identifying information (subject heading, Federal Register date and 
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.
     Make sure to submit your comments by the comment period

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) 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 revise the NAAQS, if appropriate, 
based on the revised criteria.
    Presently, EPA is reviewing the air quality criteria and NAAQS for
