Approval and Promulgation of Air Quality Implementation Plans; 
Ohio, Kentucky, and Indiana; Cincinnati-Hamilton Nonattainment Area; 
Determination of Attainment of the 1997 Annual Fine Particulate 
Standards

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

-----------------------------------------------------------------------

SUMMARY: EPA is proposing to make two determinations regarding the tri-
state Cincinnati-Hamilton (Ohio, Kentucky, and Indiana) fine 
particulate matter (PM2.5) nonattainment area (hereafter 
referred to as ``the Cincinnati Area'' or ``the Area''). First, EPA is 
proposing to determine that the Area has attained the 1997 annual 
average PM2.5 National Ambient Air Quality Standard (NAAQS). 
This proposed determination of attainment is based upon complete, 
quality-assured and certified ambient air monitoring data for the 2007-
2009 period showing that the Area has monitored attainment of the 1997 
annual PM2.5 NAAQS. If EPA finalizes this proposed 
determination of attainment, the requirements for the Area to submit an 
attainment demonstration and associated reasonably available control 
measures (RACM), a reasonable further progress (RFP) plan, contingency 
measures, and other planning State Implementation Plan (SIP) revisions 
related to attainment of the standard shall be suspended for so long as 
the Area continues to attain the annual PM2.5 NAAQS. Second, 
EPA is also proposing to determine, based on quality-assured and 
certified monitoring data for the 2007-2009 monitoring period, that the 
Area has attained the 1997 annual PM2.5 NAAQS by its 
applicable attainment date of April 5, 2010.

DATES: Comments must be received on or before July 5, 2011.

I. What actions is EPA taking?

    EPA is proposing to determine that the Cincinnati Area (comprised 
of Butler, Clermont, Hamilton, and Warren Counties in Ohio; Boone, 
Campbell and Kenton Counties in Kentucky; and a portion of Dearborn 
County in Indiana) has attaining data for the 1997 annual 
PM2.5 NAAQS.\1\ The proposal is based upon quality assured, 
quality controlled and certified ambient air monitoring data that show 
the Area has monitored attainment of the 1997 annual PM2.5 
NAAQS based on the 2007-2009 data. EPA is also proposing to determine, 
in accordance with EPA's PM2.5 Implementation Rule of April 
25, 2007 (72 FR 20664), that the Cincinnati Area has attained the 1997 
annual PM2.5 NAAQS by its applicable attainment date of 
April 5, 2010.
---------------------------------------------------------------------------

    \1\ ``1997 Annual NAAQS'' refers to both the primary and 
secondary standards, which are identical.
---------------------------------------------------------------------------

II. What is the background for these actions?

    On July 18, 1997 (62 FR 36852), EPA established an annual 
PM2.5 NAAQS at 15.0 micrograms per cubic meter ([mu]g/m\3\) 
based on a 3-year average of annual mean PM2.5 
concentrations. At that time, EPA also established a 24-hour NAAQS of 
65 [mu]g/m\3\. (This action does not address the 24-hour NAAQS.) See 40 
CFR 50.7. On January 5, 2005 (70 FR 944), EPA published its air quality 
designations and classifications for the 1997 PM2.5 NAAQS 
based upon air quality monitoring data from those monitors for calendar 
years 2001-2003. These designations became effective on April 5, 2005. 
The Cincinnati Area was designated nonattainment for the 1997 
PM2.5 NAAQS. See 40 CFR 81.336 (Ohio), 40 CFR 81.318 
(Kentucky), and 40 CFR 81.315 (Indiana).
    On October 17, 2006 (71 FR 61144), EPA retained the 1997 annual 
PM2.5 NAAQS at 15.0 [mu]g/m\3\ based on a 3-year average of 
annual mean PM2.5 concentrations, and promulgated a 24-hour 
NAAQS of 35 [mu]g/m\3\ based on a 3-year average of the 98th percentile 
of 24-hour concentrations. On November 13, 2009, EPA designated the 
Cincinnati Area as attainment for the 2006 24-hour NAAQS (74 FR 58688). 
In that action, EPA also clarified the designations for the NAAQS 
promulgated in 1997, stating that the Cincinnati Area was designated as 
nonattainment for the annual NAAQS but attainment for the 24-hour 
NAAQS. Thus, this action does not address attainment of either the 1997 
or the 2006 24-hour NAAQS.
    In response to legal challenges of the annual NAAQS promulgated in 
2006, the U.S. Court of Appeals for the District of Columbia Circuit 
(D.C. Circuit) remanded this NAAQS to EPA for further consideration. 
See American Farm Bureau Federation and National Pork Producers 
Council, et al. v. EPA, 559 F.3d 512 (D.C. Cir. 2009). However, given 
that the 1997 and 2006 annual NAAQS are essentially identical, 
attainment of the 1997 annual NAAQS would also indicate attainment of 
the remanded 2006 annual NAAQS.
    On April 25, 2007 (72 FR 20664), EPA promulgated its 
PM2.5 Implementation Rule, codified at 40 CFR part 51, 
subpart Z, in which the Agency provided guidance for state and tribal 
plans to implement the 1997 PM2.5 NAAQS. This rule, at 40 
CFR 51.1004(c), specifies some of the regulatory consequences of 
attaining the NAAQS, as discussed below.

III. Does the Cincinnati area meet the annual PM2.5 NAAQS?

A. Criteria

    This rulemaking is proposing to find that the Cincinnati Area is 
attaining the annual PM2.5 NAAQS, and provides a

[[Page 32112]]

basis for that final action. The Cincinnati Area includes certain 
counties in Ohio, Kentucky, and Indiana. The Cincinnati Area is 
comprised of Butler, Clermont, Hamilton and Warren Counties in Ohio; 
Boone, Campbell, and Kenton Counties in Kentucky; and the Lawrenceburg 
Township portion of Dearborn County in Indiana.
    Under EPA regulations at 40 CFR 50.7, the annual primary and 
secondary PM2.5 NAAQS are met when the annual arithmetic 
mean concentration, as determined in accordance with 40 CFR part 50, 
Appendix N, is less than or equal to 15.0 [mu]g/m\3\ at all relevant 
monitoring sites in the subject area.

B. Cincinnati Area Air Quality

    EPA has reviewed the ambient air monitoring data for the Cincinnati 
Area in accordance with the provisions of 40 CFR part 50, Appendix N. 
All data considered have been quality-assured, certified, and recorded 
in EPA's Air Quality System (AQS) database. This review addresses air 
quality data collected in the 3-year period from 2007-2009.
    The following table provides the annual average concentrations 
averaged over 2007-2009 at the sites in the Cincinnati Area. There are 
no PM2.5 monitoring sites for the Indiana portion of the 
Cincinnati Area. The highest 3-year average annual concentration for 
2007-2009 on this table is recorded at site 39-061-0014, recording a 3-
year average annual concentration of 15.0 [mu]g/m\3\, which is in 
attainment of the annual PM2.5 NAAQS. All other sites in the 
Area have 3-year average annual PM2.5 concentrations below 
15.0 [mu]g/m\3\.

----------------------------------------------------------------------------------------------------------------

    The Cincinnati Area did not meet the 75 percent completeness 
criteria in three cases. The NKU site began operation on August 1, 
2007, and thus did not obtain complete data for the first three 
quarters of 2007. Nevertheless, the average concentration for the 
remainder of 2007 and all of 2008 and 2009 is 12.5 [mu]g/m\3\, which 
indicates attainment at this site. This would not be considered an 
incomplete record due to it being a new site. EPA approved the closing 
of two sites in the 2007-2009 time period, which are not listed in the 
above table, Scarlet Oaks School (39-061-0043) and Hook Field Airport 
(39-017-1004). Scarlet Oaks School ended operation December 31, 2008 
and Hook Field Airport ended operation December 31, 2007. The Scarlet 
Oaks School site monitored an average concentration of 14.8 [mu]g/m\3\ 
in 2007, and an annual average concentration in 2008 of 13.3 [mu]g/
m\3\. The Hook Field Airport site monitored an annual average 
concentration of 14.6 [mu]g/m\3\ for 2007. These values are below the 
NAAQS. An examination of data from these sites is provided in the 
February 2011 technical support document available in the docket for 
this proposed rulemaking.
    More generally, EPA believes that the Cincinnati Area has a 
sufficient network of sites collecting complete data showing attainment 
to conclude that the Cincinnati Area is now meeting the annual 
PM2.5 NAAQS. In accordance with 40 CFR part 50, Appendix N 
and standard EPA practice, the review of this data is based on the 
three most recent years of complete data, generally 2007-2009. Appendix 
N does not provide for examining partial years of data, because various 
seasons of the year reflect various influences on PM2.5 
concentrations, and a partial year's data may not be representative of 
values that would be determined from a full year's data set. 
Nevertheless, EPA examined data from 2010. The complete year has not 
been certified; therefore, the data are not considered complete for 
2010. All of the 2008-2010 design values are below the 15.0 [mu]g/m\3\, 
except for the Murray Road site in Cincinnati. The Murray Road site has 
a preliminary 2008-2010 design value of 15.1 [mu]g/m\3\; however, the 
site was shut down in February of the first quarter of 2010 due to 
safety issues. The partial first quarter of 2010 data before the 
monitor shut down showed the only data above the NAAQS for the 2008-
2010 period. The 2008 design value was 14.4 [mu]g/m\3\ and the 2009 
design value was 13.4 [mu]g/m\3\. Approval was granted for the site to 
be shut down because the Carthage Fire site registered a higher design 
value and is located approximately a mile from the Murray Road site. A 
comparison of the 2007-2009 data showed the sites were well correlated 
with each other.
    The available data for 2010 are consistent with the finding, based 
on 2007-2009 data, that the Cincinnati Area is attaining the 1997 
annual PM2.5 NAAQS. On the basis of this review, EPA has 
preliminarily concluded that this Area has met and continues to meet 
the 1997 PM2.5 NAAQS. EPA is soliciting public comments on 
the issues discussed in this document. These comments will be 
considered before taking final action.

C. Has the Cincinnati area met the 1997 annual PM2.5 air 
quality standard?

    EPA has reviewed the ambient air monitoring data for 
PM2.5, consistent with the requirements contained in 40 CFR 
part 50 and recorded the data in the EPA AQS database, for the 
Cincinnati Area from 2007 through the present time.
    On the basis of that review, EPA proposes to determine that this 
Area has attained and continues to attain the 1997 annual 
PM2.5 NAAQS based on the quality-assured data for the 2007-
2009 and 2008-2010 monitoring periods. In

[[Page 32113]]

addition, based on EPA's review of the data for 2007-2009, and in 
accordance with section 179(c)(1) of the CAA and EPA's regulations, EPA 
proposes to determine that the Area attained the 1997 annual 
PM2.5 NAAQS by its applicable attainment date of April 5, 
2010.

IV. What is the effect of these actions?

    If this proposed determination of attainment is made final, the 
requirements for the Cincinnati Area to submit an attainment 
demonstration and associated RACM, a RFP plan, contingency measures, 
and any other planning SIPs related to attainment of the 1997 annual 
PM2.5 NAAQS would be suspended for so long as the Area 
continues to attain the PM2.5 NAAQS. See 40 CFR 51.1004(c).
    If this proposed rulemaking is finalized and EPA subsequently 
determines, after notice-and-comment rulemaking in the Federal 
Register, that the Area has violated the annual PM2.5 NAAQS, 
the basis for the suspension of the specific requirements would no 
longer exist for the Cincinnati Area, and the Area would thereafter 
have to address the applicable requirements. See 40 CFR 51.1004(c).
    Finalizing this proposed action would not constitute a 
redesignation of the Area to attainment of the annual PM2.5 
NAAQS under section 107(d)(3) of the Clean Air Act (CAA). Further, 
finalizing this proposed action does not involve approving maintenance 
plans for the Area as required under section 175A of the CAA, nor would 
it find that the Area has met all other requirements for redesignation. 
Even if EPA finalizes the proposed action, the designation status of 
the Cincinnati Area would remain nonattainment for the 1997 annual 
PM2.5 NAAQS until such time as EPA determines that the Area 
meets the CAA requirements for redesignation to attainment and takes 
action to redesignate the Area.
    This action is only a proposed determination of attainment that the 
Cincinnati Area has attained the 1997 annual PM2.5 NAAQS. 
This action does not address the 24-hour PM2.5 NAAQS.
    If the Cincinnati Area continues to monitor attainment of the 
annual PM2.5 NAAQS, the requirements for the Cincinnati Area 
to submit an attainment demonstration and associated RACM, a RFP plan, 
contingency measures, and any other planning SIPs related to attainment 
of the annual PM2.5 NAAQS will remain suspended.
    In addition, if EPA's separate and independent proposed 
determination that the Area has attained the 1997 annual 
PM2.5 standard by its applicable attainment date (April 5, 
2010) is finalized, EPA will have met its requirement pursuant to 
section 179(c)(1) of the CAA to make a determination based on the 
Area's air quality data as of the attainment date whether the Area 
attained the standard by that date.
    These two actions described above are proposed determinations 
regarding the Cincinnati Area's attainment status only with respect to 
the 1997 annual PM2.5 NAAQS. Today's actions do not address 
the 24-hour PM2.5 NAAQS.

V. Statutory and Executive Order Reviews

    These actions propose 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, these 
proposed actions:
     Are not ``significant regulatory actions'' subject to 
review by the Office of Management and Budget under Executive Order 
12866 (58 FR 51735, October 4, 1993);
     Do not impose an information collection burden under the 
provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
     Are 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.);
     Do 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);
     Do not have Federalism implications as specified in 
Executive Order 13132 (64 FR 43255, August 10, 1999);
     Are not economically significant regulatory actions based 
on health or safety risks subject to Executive Order 13045 (62 FR 
19885, April 23, 1997);
     Are not significant regulatory actions subject to 
Executive Order 13211 (66 FR 28355, May 22, 2001);
     Are 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
     Do 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, 
these proposed 1997 annual PM2.5 NAAQS determinations for 
the Cincinnati Area do 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.
