**ACTION :**  Proposed rule.

**SUMMARY :**  On April 24, 2012, EPA proposed to determine that the Milwaukee-Racine, Wisconsin area had attained the 2006 24-hour fine particle (2006 PM 2.5 ) National Ambient Air Quality Standard (NAAQS). EPA
received several comments on the original proposal, including one suggesting that the suspension of certain Clean Air Act (CAA) requirements cannot be applied in this instance because it only pertains to the 1997

PM 2.5 NAAQS and not to the 2006 PM 2.5 NAAQS. As a result, we are reproposing a narrow portion of our original
determination to address this issue. We
will address all comments received on the original proposal and this proposal
in our final notice. **DATES :**  Comments must be received on or before January 28, 2013.

1 While EPA recognizes that 40 CFR 51.1004(c) does not itself expressly apply to the 2006 PM 2.5 standard, the statutory interpretation that it embodies is identical and is applicable to both the
1997 and 2006 PM 2.5 standards. your estimate in sufficient detail to allow for it to be reproduced.

6. Provide specific examples to illustrate your concerns, and suggest
alternatives.

7. Explain your views as clearly as possible, avoiding the use of profanity or personal threats.

8. Make sure to submit your comments by the comment period
deadline identified.

II. What action is EPA taking?

On April 24, 2012, at 77 FR 24436, EPA proposed to determine that the Milwaukee-Racine, Wisconsin area had
attained the 2006 PM 2.5 NAAQS. EPA received several comments on the original proposal, including one suggesting that 40 CFR 51.1004(c) cannot be applied in this instance because it only pertains to the 1997

PM 2.5 NAAQS and not to the 2006 PM 2.5 NAAQS. 40 CFR 51.1004(c) pertains to the suspension of certain CAA requirements including the requirements for Wisconsin to submit an attainment demonstration, associated reasonably available control measures (RACM) to include reasonably available control technology (RACT), a reasonable further progress (RFP) plan, contingency measures, and any other planning State Implementation Plans (SIPs) related to
attainment of the 2006 PM 2.5 NAAQS, and continues until such time, if any, that EPA subsequently determines that
the area has violated the 2006 PM 2.5 NAAQS.

Our original proposal did not clearly explain EPA’s views on the applicability of CFR 51.1004(c) to the 2006 PM 2.5 NAAQS. As a result, in this re-proposal, EPA today is explaining its views and soliciting comment on this specific
issue. We will address all comments received on the original proposal and this proposal in our final notice.

III. What is the background for this
action?

In April 2007, EPA issued its PM 2.5 Implementation Rule for the 1997 PM 2.5 standard. 72 FR 20586 (April 25, 2007). In March 2012, EPA published implementation guidance for the 2006

PM 2.5 standard. See Memorandum from Stephen D. Page, Director, Office of Air Quality Planning and Standards, ‘‘Implementation Guidance for the 2006 24-Hour Final Particle (PM 2.5 ) National Ambient Air Quality Standards (NAAQS)’’ (March 2, 2012). In that guidance, EPA stated its view ‘‘that the overall framework and policy approach
of the 2007 PM 2.5 Implementation Rule continues to provide effective and appropriate guidance on the EPA’s interpretation of the general statutory requirements that states should address in their SIPs. In general, EPA believes that the interpretations of the statute in
the framework of the 2007 PM 2.5 Implementation Rule are relevant to the statutory requirements for the 2006 24-
hour PM 2.5 NAAQS * * *.’’ Id., page 1. With respect to the statutory provisions applicable to 2006 PM 2.5 implementation, the guidance emphasized that ‘‘EPA outlined its interpretation of many of these provisions in the 2007 PM 2.5 Implementation Rule. In addition to regulatory provisions, EPA provided substantial general guidance for attainment plans for PM 2.5 in the preamble to the final the [ sic] 2007

PM 2.5 Implementation Rule.’’ Id., page 2. In keeping with the principles set forth in the guidance, and with respect to the
effect of a determination of attainment
for the 2006 PM 2.5 standard, EPA is applying the same interpretation with respect to the implications of clean data
determinations that it set forth in the preamble to the 1997 PM 2.5 standard and in the regulation that embodies this interpretation. 40 CFR 51.1004(c). 1 EPA has long applied this interpretation in regulations and individual rulemakings
for the 1-hour ozone and 1997 8-hour ozone standards, the PM–10 standard,
and the lead standard. While EPA recognizes that the regulatory provisions of 51.1004(c) do not explicitly apply to
the 2006 PM 2.5 standard, the statutory interpretation that it embodies is
identical for both the 1997 PM 2.5 and

2006 PM 2.5 standards.

History and Basis of EPA’s Clean Data Policy

Following enactment of the CAA Amendments of 1990, EPA promulgated its interpretation of the requirements for implementing the NAAQS in the general preamble for the Implementation of Title I of the CAA Amendments of 1990 (General Preamble) 57 FR 13498, 13564 (April 16, 1992). In 1995, based on the interpretation of CAA sections 171 and 172, and section 182 in the General Preamble, EPA set forth what has
become known as its ‘‘Clean Data Policy’’ for the 1-hour ozone NAAQS.
See Memorandum from John S. Seitz, Director, Office of Air Quality Planning and Standards, ‘‘Reasonable Further Progress, Attainment Demonstration, and Related Requirements for Ozone Nonattainment Areas Meeting the Ozone National Ambient Air Quality Standard’’ (May 10, 1995). In 2004, EPA
indicated its intention to extend the Clean Data Policy to the PM2.5 NAAQS.
See Memorandum from Stephen Page, Director, EPA Office of Air Quality Planning and Standards, ‘‘Clean Data Policy for the Fine Particle National Ambient Air Quality Standards’’ (December 14, 2004). Since 1995, EPA has applied its interpretation under the Clean Data Policy in many rulemakings, suspending certain attainment-related planning requirements for individual areas, based on a determination of

attainment. See 60 FR 36723 (July 18, 1995) (Salt Lake and Davis Counties, Utah, 1-hour ozone); 61 FR 20458 (May 7, 1996) (Cleveland-Akron-Lorain, Ohio, 1-hour ozone); 61 FR 31831 (June 21, 1996) (Grand Rapids, Michigan, 1-hour ozone); 65 FR 37879 (June 19, 2000) (Cincinnati-Hamilton, Ohio-Kentucky, 1-hour ozone); 66 FR 53094 (October 19, 2001) (Pittsburgh-Beaver Valley, Pennsylvania, 1-hour ozone); 68 FR 25418 (May 12, 2003) (St. Louis, Missouri-Illinois, 1-hour ozone); 69 FR 21717 (April 22, 2004) (San Francisco Bay Area, California, 1-hour ozone), 75 FR 6570 (February 10, 2010) (Baton Rouge, Louisiana, 1-hour ozone), 75 FR 27944 (May 19, 2010) (Coso Junction, California, PM 10).

EPA also incorporated its interpretation under the Clean Data Policy in several implementation rules.

See Clean Air Fine Particle Implementation Rule, 72 FR 20586 (April 25, 2007); Final Rule To Implement the 8-Hour Ozone National Ambient Air Quality Standard—Phase 2, 70 FR 71612 (November 29, 2005). The Court of Appeals for the District of Columbia Circuit (D.C. Circuit) upheld EPA’s rule embodying the Clean Data Policy for the 1997 8-hour ozone
standard. NRDC v. EPA, 571 F.3d 1245 (D.C. Cir. 2009). Other courts have
reviewed and considered individual rulemakings applying EPA’s Clean Data Policy, and have consistently upheld them in every case. Sierra Club v. EPA, 99 F.3d 1551 (10th Cir. 1996); Sierra Club v. EPA, 375 F.3d 537 (7th Cir. 2004); Our Children’s Earth Foundation

v. EPA, No. 04–73032 (9th Cir. June 28, 2005 (Memorandum Opinion)), Latino
Issues Forum v. EPA, Nos. 06–75831 and 08–71238 (9th Cir. March 2, 2009 (Memorandum Opinion)).

EPA sets forth below a brief explanation of the statutory interpretations in the Clean Data Policy. EPA also incorporates the discussions of its interpretation set forth in prior rulemakings, including the 1997 PM2.5 implementation rulemaking. See 72 FR

3 This discussion refers to subpart 1 because subpart 1 contains the requirements relating to
attainment of the 2006 PM 2.5 NAAQS. 4 This interpretation was adopted in the General Preamble, see 57 FR 13498, and has been upheld as applied to the Clean Data Policy, as well as to
nonattainment SIP submissions. See NRDC v. EPA, 571 F.3d 1245 (DC Cir. 2009); Sierra Club v. EPA, 294 F.3d 155 (DC Cir. 2002). 20586, at 20603–20605 (April 25, 2007). 2

The Clean Data Policy represents EPA’s interpretation that certain requirements of subpart 1 of part D of the CAA are by their terms not applicable to areas that are currently attaining the NAAQS. 3 As explained below, the specific requirements that are inapplicable to an area attaining the standard are the requirements to submit a SIP that provides for: Attainment of the NAAQS; implementation of all RACM; RFP; and implementation of contingency measures for failure to meet
deadlines for RFP and attainment.

CAA section 172(c)(1), the requirement for an attainment demonstration, provides in relevant part that SIPs ‘‘shall provide for attainment of the [NAAQS].’’ EPA has interpreted this requirement as not applying to areas that have already attained the
standard. If an area has attained the standard, there is no need to submit a plan demonstrating how the area will
reach attainment. In the General Preamble (57 FR 13564), EPA stated that no other measures to provide for attainment would be needed by areas seeking redesignation to attainment
since ‘‘attainment will have been
reached.’’ See also Memorandum from John Calcagni, ‘‘Procedures for Processing Requests to Redesignate Areas to Attainment,’’ (September 4, 1992), at page 6.

A component of the attainment plan specified under section 172(c)(1) is the requirement to provide for ‘‘the implementation of all RACM as expeditiously as practicable’’. Since
RACM is an element of the attainment demonstration, see General Preamble (57 FR 13560), for the same reason the attainment demonstration no longer applies by its own terms, RACM also no longer applies to areas that EPA has determined have attained the NAAQS. Furthermore, EPA has consistently interpreted this provision to require only implementation of such potential
RACM measures that could advance
attainment. 4 Thus, where an area is already attaining the standard, no
additional RACM measures are required. EPA’s interpretation that the statute requires only implementation of
the RACM measures that would advance attainment was upheld by the United States Court of Appeals for the Fifth Circuit ( Sierra Club v. EPA, 314 F.3d 735, 743–745, 5th Cir. 2002) and by the United States Court of Appeals for the DC Circuit ( Sierra Club v. EPA, 294 F. 3d 155, 162–163, DC Cir. 2002). See alsothe final rulemakings for PittsburghBeaver Valley, Pennsylvania, 66 FR 53096 (October 19, 2001) and St. Louis, Missouri-Illinois, 68 FR 25418 (May 12, 2003).

CAA section 172(c)(2) provides that SIP provisions in nonattainment areas must require ‘‘reasonable further progress.’’ The term ‘‘reasonable further progress’’ is defined in section 171(1) as
‘‘such annual incremental reductions in emissions of the relevant air pollutant as are required by this part or may reasonably be required by the Administrator for the purpose of ensuring attainment of the applicable NAAQS by the applicable date.’’ Thus, by definition, the ‘‘reasonable further progress’’ provision under subpart 1 requires only such reductions in emissions as are necessary to attain the NAAQS. If an area has attained the NAAQS, the purpose of the RFP requirement has been fulfilled, and since the area has already attained, showing that the state will make RFP towards attainment ‘‘[has] no meaning at that point.’’ General Preamble, 57 FR 13498, 13564 (April 16, 1992).

CAA section 172(c)(9) provides that
SIPs in nonattainment areas ‘‘shall provide for the implementation of specific measures to be undertaken if
the area fails to make reasonable further progress, or to attain the [NAAQS] by the attainment date applicable under this part. Such measures shall be included in the plan revision as contingency measures to take effect in any such case without further action by the State or [EPA].’’ This contingency measure requirement is inextricably tied
to the RFP and attainment demonstration requirements. Contingency measures are implemented if RFP targets are not achieved, or if attainment is not realized by the
attainment date. Where an area has already achieved attainment, it has no need to rely on contingency measures to
come into attainment or to make further progress to attainment. As EPA stated in
the General Preamble: ‘‘The section 172(c)(9) requirements for contingency measures are directed at ensuring RFP and attainment by the applicable date.’’
See 57 FR 13564. Thus these requirements no longer apply when an
area has attained the standard.

It is important to note that should an
area attain the 2006 PM2.5 standard based on three years of data, its obligation to submit an attainment demonstration and related planning submissions is suspended only for so long as the area continues to attain the standard. If EPA subsequently determines, after notice and comment rulemaking, that the area has violated the NAAQS, the requirements for
Wisconsin to submit a SIP to meet the previously suspended requirements
would be reinstated. It is likewise important to note that the area remains designated nonattainment pending a further redesignation action.

IV. Statutory and Executive Order
Reviews.

This action proposes to make a
determination of attainment based on air quality, and would, if finalized, result in the suspension of certain Federal requirements, and it would not impose additional requirements beyond those imposed by state law. For that reason, this proposed action:

• Is not a ‘‘significant regulatory action’’ subject to review by the Office of Management and Budget under Executive Order 12866 (58 FR 51735, October 4, 1993);

• Does not impose an information collection burden under the provisions of the Paperwork Reduction Act (44

U.S.C. 3501 et seq. );

• Is certified as not having a significant economic impact on a
substantial number of small entities under the Regulatory Flexibility Act (5

U.S.C. 601 et seq. );


### 76430 Federal Register / Vol. 77, No. 249 / Friday, December 28, 2012 / Proposed Rules

• Does not contain any unfunded mandate or significantly or uniquely affect small governments, as described
in the Unfunded Mandates Reform Act of 1995 (Pub. L. 104–4);

• Does not have Federalism implications as specified in Executive Order 13132 (64 FR 43255, August 10, 1999);

• Is not an economically significant regulatory action based on health or safety risks subject to Executive Order 13045 (62 FR 19885, April 23, 1997);

• Is not a significant regulatory action subject to Executive Order 13211 (66 FR 28355, May 22, 2001);

• Is not subject to requirements of Section 12(d) of the National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 note) because application of those requirements would be inconsistent with the CAA; and

• Does not provide EPA with the discretionary authority to address, as appropriate, disproportionate human health or environmental effects, using practicable and legally permissible methods, under Executive Order 12898 (59 FR 7629, February 16, 1994). In addition, this proposed 2006 PM 2.5 clean NAAQS data determination for the Milwaukee-Racine, Wisconsin area does not have tribal implications as specified by Executive Order 13175 (65 FR 67249, November 9, 2000), because the SIP is not approved to apply in Indian country located in the state, and EPA notes that it will not impose
substantial direct costs on tribal governments or preempt tribal law.

**AGENCY :**  Environmental Protection Agency (EPA). **ACTION :**  Proposed rule.

**SUMMARY :**  EPA is proposing to approve revisions to the Wisconsin State Implementation Plan (SIP), submitted by the Wisconsin Department of Natural Resources (WDNR) to EPA on May 4, 2011, June 20, 2012, and September 28, 2012. The proposed revisions modify Wisconsin’s Prevention of Significant Deterioration (PSD) program to establish appropriate emission thresholds for determining which new stationary sources and modification projects become subject to Wisconsin’s PSD permitting requirements for their greenhouse gas (GHG) emissions. Additionally, these revisions propose to defer until July 21, 2014, the application of the PSD permitting requirements to biogenic carbon dioxide (CO 2) emissions from bioenergy and other biogenic stationary sources in the State of Wisconsin. EPA is proposing approval
of Wisconsin’s revisions because the Agency has made the preliminary
determination that these revisions are in
accordance with the Clean Air Act (CAA) and EPA regulations regarding PSD permitting for GHGs.
