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 (healthbased) 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 revise the NAAQS, if appropriate, based on the revised criteria. Presently, EPA is reviewing the secondary NAAQS for oxides of nitrogen and sulfur.1 The document 1 The EPA’s initial overall plan for this review was presented in the Integrated Review Plan for the National Ambient Air Quality Standards for Nitrogen Dioxide and Sulfur Dioxide (EPA–452/R– 08–006, December 2007).

This document, which builds upon the historical ‘‘Staff Paper,’’ will serve to ‘‘bridge the gap’’ between the available scientific information and the judgments required of the Administrator in determining whether it is appropriate to retain or revise the standards.2 The current and potential alternative standards for oxides of nitrogen and sulfur are considered in terms of the basic elements of the NAAQS: indicator, averaging time, form, and level. The Policy Assessment builds upon information presented in the Integrated Science Assessment for Oxides of Nitrogen and Sulfur— Ecological Criteria: Final report (ISA, EPA EPA/600/R–08/082F, December 2008) and the quantitative risk and exposure assessment document (REA)— Risk and Exposure Assessment for Review of the Secondary National Ambient Air Quality Standards for Oxides of Nitrogen and Oxides of Sulfur (EPA–452/R–09–008a and EPA–452/R– 09–008b; September 2009). A first draft Policy Assessment (EPA– 452/P–10–006) was released in March 2010 to facilitate discussion with the Clean Air Scientific Advisory Committee (CASAC) at an April 1–2, 2010 meeting on the overall structure, areas of focus, and level of detail to be included in the Policy Assessment (75 FR 10479–10481, March 2010). CASAC’s comments on the first draft Policy Assessment encouraged the development of a document focused on the key policy-relevant issues that draws from and is not repetitive of information in the ISA and REA. These comments were considered in developing a second draft Policy Assessment (EPA 452/P–10–008, September 2010).

ACTION: Notice of withdrawal of adequacy. AGENCY: EPA is notifying the public that EPA has withdrawn its previous adequacy finding on the 2012 motor vehicle emission budgets (MVEBs) for Connecticut’s two 8-hour ozone nonattainment areas. EPA has withdrawn the adequacy finding because Connecticut Department of Environmental Protection (CT DEP) withdrew its 2012 motor vehicle emission budgets from its eight-hour ozone attainment demonstration SIP for both ozone nonattainment areas. As a result of our finding, Connecticut can not use these 2012 motor vehicle emission budgets for future conformity determinations. DATES: This finding is effective March 2, 2011.

Cooke, Environmental Scientist, Air Quality Planning Unit, U.S. Environmental Protection Agency, EPA New England Regional Office, Five Post Office Square, Suite 100 (CAQ), Boston, MA 02109–3912, (617) 918– 1668, cooke.donald@epa.gov. SUPPLEMENTARY INFORMATION: Throughout this document, whenever ‘‘we,’’ ‘‘us’’ or ‘‘our’’ is used, we mean EPA. Today’s action is simply an announcement of a finding that we have already made. On February 1, 2008, Connecticut submitted 2008, 2009, and 2012 summer SUMMARY: PO 00000 Frm 00030 Fmt 4703 Sfmt 4703 day volatile organic compound (VOC) and nitrogen oxides (NOx) MVEBs for the Connecticut portion of the New York-Northern New Jersey-Long Island, NY–NJ–CT (Southwest Connecticut) 8hour ozone nonattainment area and for the Greater Connecticut 8-hour ozone nonattainment area. These MVEBs were submitted to EPA as part of the 8-hour ozone attainment demonstrations and reasonable further progress plans for these areas. Although not required by the Clean Air Act or EPA regulation, Connecticut included the 2012 budgets in its ozone attainment demonstrations based on uncertainty as to whether attainment would be met by the applicable June 15, 2010 attainment date for the two nonattainment areas. EPA found Connecticut’s 2008, 2009, and 2012 MVEBs adequate for transportation conformity purposes. See 73 FR 33428; June 12, 2008. On August 23, 2010, CT DEP withdrew the 2012 MVEBs from its 8hour ozone attainment demonstration SIP for both ozone nonattainment areas. At that time, CT DEP also requested that EPA withdraw the adequacy findings for the 2012 MVEBs, since both ozone nonattainment areas have monitored air quality data demonstrating attainment of the 1997 8-hour ozone National Ambient Air Quality Standard, and the 2012 MVEBs are no longer necessary to ensure attainment.1 Connecticut’s request to withdraw the 2012 MVEBs was announced on EPA’s conformity Web site, and received no comments. (See https://www.epa.gov/ otaq/stateresources/transconf/ adequacy.htm. Once there, click on ‘‘What SIP submissions are currently under EPA adequacy review?’’) On December 30, 2010, EPA sent a letter to the CT DEP withdrawing our previous adequacy finding on the 2012 MVEBs for the Southwest Connecticut and the Greater Connecticut 8-hour ozone nonattainment areas. The 2012 MVEBs are withdrawn for transportation conformity purposes. However, the 2008 (reasonable further progress) MVEBs and the 2009 (attainment) MVEBs that were previously deemed adequate, remain adequate for transportation conformity purposes. Authority: 42 U.S.C. 7401–7671 q. 1 EPA has determined that the Greater Connecticut area has attained the 1997 8-hour ozone standard. See 75 FR 53219; August 31, 2010. EPA has not yet taken action regarding the Southwest Connecticut area. E:\FR\FM\15FEN1.SGM 15FEN1

    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

announced today, Policy Assessment for the Review of the Secondary 
National Ambient Air Quality Standards for Oxides of Nitrogen and 
Sulfur, contains staff analyses of the scientific bases for alternative 
policy options for consideration by the Agency prior to rulemaking. 
This document, which builds upon the historical ``Staff Paper,'' will 
serve to ``bridge the gap'' between the available scientific 
information and the judgments required of the Administrator in 
determining whether it is appropriate to retain or revise the 
standards.\2\ The current and potential alternative standards for 
oxides of nitrogen and sulfur are considered in terms of the basic 
elements of the NAAQS: indicator, averaging time, form, and level. The 
Policy Assessment builds upon information presented in the Integrated 
Science Assessment for Oxides of Nitrogen and Sulfur--Ecological 
Criteria: Final report (ISA, EPA EPA/600/R-08/082F, December 2008) and 
the quantitative risk and exposure assessment document (REA)--Risk and

    A first draft Policy Assessment (EPA-452/P-10-006) was released in 
March 2010 to facilitate discussion with the Clean Air Scientific 
Advisory Committee (CASAC) at an April 1-2, 2010 meeting on the overall 
structure, areas of focus, and level of detail to be included in the 
Policy Assessment (75 FR 10479-10481, March 2010). CASAC's comments on 
the first draft Policy Assessment encouraged the development of a 
document focused on the key policy-relevant issues that draws from and 
is not repetitive of information in the ISA and REA. These comments 
were considered in developing a second draft Policy Assessment (EPA 
452/P-10-008, September 2010). The EPA presented an overview of the 
second draft Policy Assessment at a CASAC meeting on October 6-7, 2010 
(75 FR 54871-54872).
    CASAC (EPA-CASAC-11-003) and public comments on the second draft 
Policy Assessment were considered by EPA staff in developing both the 
January 14, 2011 version and this current version of the final Policy 
Assessment, which reflects final editing and formatting, and is 
available through the Agency's Technology Transfer Network (TTN) Web 
site at https://www.epa.gov/ttn/naaqs/standards/no2so2sec/cr_pa.html. 
CASAC has requested a February 15-16, 2011, meeting to review EPA's 
final Policy Assessment.
