Download as PDF 61098 Federal Register / Vol. 76, No. 191 / Monday, October 3, 2011 / Notices Document which may be obtained as explained above. V. Statutory and Executive Order Reviews My decision will affect not only persons in California but also the manufacturers outside the State who must comply with California’s requirements in order to produce new motor vehicles for sale in California. For this reason, I hereby determine and find that this is a final action of national applicability. This action is not a rule as defined by Executive Order 12866. Therefore, it is exempt from review by the Office of Management and Budget as required for rules and regulations by Executive Order 12866. In addition, this action is not a rule as defined in the Regulatory Flexibility Act, 5 U.S.C. 601(2). Therefore, EPA has not prepared a supporting regulatory flexibility analysis addressing the impact of this action on small business entities. Further, the Congressional Review Act, 5 U.S.C. 801, et seq., as added by the Small Business Regulatory Enforcement Fairness Act of 1996, does not apply because this action is not a rule for purposes of 5 U.S.C. 804(3). Finally, the Administrator has delegated the authority to make determinations regarding waivers under § 209(b) of the Act to the Assistant Administrator for Air and Radiation. Dated: September 26, 2011. Gina McCarthy, Assistant Administrator for Air and Radiation.

ACTION: Notice of Availability. AGENCY: On September 30, 2011, the EPA publically released the final report entitled Exposure Factors Handbook: 2011 Edition. The document was prepared by the National Center for Environmental Assessment (NCEA) within EPA’s Office of Research and Development. The Exposure Factors Handbook: 2011 Edition provides information on various physiological and behavioral factors commonly used srobinson on DSK4SPTVN1PROD with NOTICES SUMMARY: VerDate Mar<15>2010 16:42 Sep 30, 2011 Jkt 223001 in assessing exposure to environmental chemicals. The handbook was first published in 1989 and was updated in 1997. This edition incorporates information made available from 1997 up until July 2011. It also reflects the revisions made to the Child-Specific Exposure Factors Handbook, which was last updated and published in 2008. Each chapter in the Exposure Factors Handbook: 2011 Edition presents recommended values for the exposure factors covered in that particular chapter’s exposure route as well as a discussion of the underlying data used in developing the recommendations. The Exposure Factors Handbook: 2011 Edition (EPA/600/R–09/052F) is available via the Internet at https:// www.epa.gov/ncea. DATES: This report was posted publically on September 30, 2011. ADDRESSES: The report is available primarily via the Internet on the National Center for Environmental Assessment’s home page under the Recent Additions and Publications menus at https://www.epa.gov/ncea.

SUPPLEMENTARY INFORMATION: I. Information About the Project/ Document The Exposure Factors Handbook: 2011 Edition provides a summary of the available statistical data on various factors used in assessing human exposure. These factors include: drinking water consumption; mouthing behavior; soil ingestion rates; inhalation rates; dermal factors, including skin area and soil adherence factors; consumption of fruits and vegetables, fish, meats, dairy products, and homegrown foods; human milk intake; human activity factors; consumer product use; and building characteristics. This handbook is intended for use by exposure assessors, within the Agency as well as those outside, as a reference tool and primary source of exposure factor information. It may be used by scientists, economists, and other interested parties as a source of data PO 00000 Frm 00027 Fmt 4703 Sfmt 4703 and/or U.S. EPA recommendations on numeric estimates for behavioral and physiological characteristics needed to estimate exposure to environmental agents. Recommended values are available for the general population and, for most of the exposure factors, are also available by age, sex, as well as for other populations that may have characteristics different from the general population.

II. Background

    The purpose of this notice is to solicit public comments on EPA's 
recently posted draft non-binding guidance titled, ``Guidance for 1-
Hour SO2 NAAQS SIP Submissions.'' This document is available 
online at https://www.epa.gov/airquality/sulfurdioxide/implement.html or 
within the associated docket, EPA-HQ-OAR-2010-1059.
    The draft guidance document is intended to assist state and tribal 
governments in preparing State Implementation Plan (SIP) submittals 
under section 110(a)(1) of the Clean Air Act (CAA) to address 
implementation, maintenance, and enforcement of the 1-hour primary 
sulfur dioxide (SO2) National Ambient Quality Standards 
(NAAQS). The CAA directs states to submit these SIPs to EPA by no later 
than June 3, 2013, which is 3 years after promulgation of the primary 
SO2 NAAQS. To be approved, the EPA would expect the SIP 
submittals to demonstrate through the use of refined air quality 
dispersion modeling that the affected areas will attain the standard as 
expeditiously as practicable. This draft guidance provides the basic 
information that states, tribes and emission sources would need to 
address the section 110(a)(1) SIP submittal for the 1-hour 
SO2 NAAQS including modeling guidance. After receiving 
timely submitted public comments on the draft guidance, the EPA plans 
to issue updated non-binding guidance. In addition, the EPA will 
continue to work closely with states and tribes to address issues 
arising under the section 110(a)(1) SIP submittals.
    EPA invites public comment on all aspects of this draft guidance 
during the 30-day comment period. The draft guidance is not a 
regulation or any other kind of final action and does not establish 
binding requirements on the EPA or any state, local, or tribal agency 
or any emissions source. While the EPA has established a docket and is 
requesting public comment on the draft guidance, this procedure does 
not alter the nature or effect of the draft guidance and does not 
constitute a formal rulemaking process or require the EPA to respond to 
public comments in the updated guidance before the EPA or other 
agencies may use the guidance in reaching decisions related to SIPs 
submitted under section 110(a)(1). The EPA retains the discretion to 
revise its guidance, issue additional guidance, propose regulations as 
appropriate, and to utilize information submitted in public comments to 
inform future decisions. Because this draft guidance does not 
constitute a formal rulemaking action, the EPA is not required to 
respond to comments, but intends to take significant comments under 
consideration in amending or updating

[[Page 61100]]

the non-binding guidance. To the extent that the EPA determines that 
comments received during the 30-day comment period justify corrections 
or clarifications to the guidance, the EPA may revise and reissue the 
guidance and post the revised document at: https://www.epa.gov/airquality/sulfurdioxide/implement.html.
    Please refer to the ADDRESSES section above in this document for
