[EPA-R05-OAR-2010-0210; FRL-9201-3]


Approval and Promulgation of Air Quality Implementation Plans; 
Indiana; Kentucky; Louisville Nonattainment Area; Determination of 
Attainment of the Fine Particle Standard

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: EPA is proposing to determine that the bi-state Louisville 
(Indiana and Kentucky) fine particle (PM<INF>2.5</INF>) nonattainment 
area has attained the 1997 annual average PM<INF>2.5</INF> National 
Ambient Air Quality Standard (NAAQS). This proposed determination 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 annual PM<INF>2.5</INF> NAAQS. If EPA 
finalizes this proposed determination, 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 
PM<INF>2.5</INF> NAAQS.

DATES: Comments must be received on or before October 14, 2010.

SUPPLEMENTARY INFORMATION: Throughout this document whenever ``we,'' 
``us,'' or ``our'' is used, we mean EPA.
    This supplementary information section is arranged as follows:

I. What action is EPA taking?
II. What is the background for this action?
III. Does the Louisville area meet the annual PM<INF>2.5</INF> 
standard?
    A. Criteria
    B. Louisville Area Air Quality

V. Statutory and Executive Order Reviews

I. What action is EPA taking?

    EPA is proposing to determine that the Louisville PM<INF>2.5</INF> 
annual standard nonattainment area (which consists of portions in both 
Indiana and Kentucky) has attained the 1997 annual PM<INF>2.5</INF> 
NAAQS. The proposal is based upon complete, quality-assured, and 
certified ambient air monitoring data for the 2007-2009 monitoring 
period that show that the area has monitored attainment of the 1997 
annual PM<INF>2.5</INF> NAAQS.

II. What is the background for this action?

    On July 18, 1997 (62 FR 36852), EPA established an annual 
PM<INF>2.5</INF> NAAQS at 15.0 micrograms per cubic meter ([mu]g/m\3\) 
based on a three-year average of annual mean PM<INF>2.5</INF> 
concentrations. At that time, EPA also established a 24-hour standard 
of 65 [mu]g/m\3\ (today's action does not address the 24-hour 
standard). See 40 CFR 50.7. On January 5, 2005 (70 FR 944), EPA 
published its air quality designations and classifications for the 1997 
PM<INF>2.5</INF> NAAQS based upon air quality monitoring data from 
those monitors for calendar years 2001-2003. These designations became 
effective on April 5, 2005. The Louisville area was designated 
nonattainment for the 1997 PM<INF>2.5</INF> NAAQS. See 40 CFR 81.315 
(Indiana) and 40 CFR 81.318 (Kentucky).
    On October 17, 2006 (71 FR 61144), EPA retained the 1997 annual 
PM<INF>2.5</INF> NAAQS at 15.0 [mu]g/m\3\ based on a three-year average 
of annual mean PM<INF>2.5</INF> concentrations, and promulgated a 24-
hour standard of 35 [mu]g/m\3\ based on a three-year average of the 
98th percentile of 24-hour concentrations. On November 13, 2009, EPA 
designated the Louisville area as attainment for the 2006 24-hour 
standard (74 FR 58688). In that action, EPA also clarified the 
designations for the NAAQS promulgated in 1997, stating that the 
Louisville area was designated as nonattainment for the annual standard 
but attainment for the 24-hour standard. Thus, today's action does not 
address attainment of either the 1997 or the 2006 24-hour standard.
    In response to legal challenges of the annual standard promulgated 
in 2006, the U.S. Court of Appeals for the District of Columbia Circuit 
(D.C. Circuit) remanded this standard 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 standards are essentially identical, 
attainment of the 1997 annual standard would also indicate attainment 
of the remanded 2006 annual standard.
    On April 25, 2007 (72 FR 20664), EPA promulgated its 
PM<INF>2.5</INF> 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 PM<INF>2.5</INF> standards. This rule, at 
40 CFR 51.1004(c),

[[Page 55727]]

specifies some of the regulatory consequences of attaining the 
standard, as discussed below.

III. Does the Louisville area meet the annual PM<INF>2.5</INF> 
standard?

A. Criteria

    Today's rulemaking assesses whether the Louisville PM<INF>2.5</INF> 
nonattainment area is attaining the 1997 annual PM<INF>2.5</INF> NAAQS. 
The Louisville nonattainment area includes certain counties in Indiana 
and in Kentucky. The Indiana portion of this area is defined at 40 CFR 
81.315, and comprises Clark and Floyd Counties and a portion of 
Jefferson County (Madison Township). The Kentucky portion of this area 
is defined at 40 CFR 81.318, and includes Bullitt and Jefferson 
Counties.
    Under EPA regulations at 40 CFR 50.7, the annual primary and 
secondary PM<INF>2.5</INF> standards 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 [micro]g/m\3\ at all relevant 
monitoring sites in the subject area.

B. Louisville Area Air Quality

    EPA has reviewed the ambient air monitoring data for the Louisville 
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 database. This review addresses air quality 
data collected in the three-year period from 2007 to 2009.
    The following table provides the annual average concentrations 
averaged over 2007 to 2009 at all sites in the Louisville area with at 
least 75 percent complete data in each quarter for each of those three 
years, including sites in both Indiana and Kentucky. The highest three-
year average annual concentration for 2007 to 2009 on this table is 
recorded at site 18-019-0006, recording a three-year average annual 
concentration of 14.6 [micro]g/m\3\. All sites in the area have three-
year average annual PM<INF>2.5</INF> concentrations below 15.0 
[micro]g/m\3\.

----------------------------------------------------------------------------------------------------------------
                                                                                                      Annual
                                                                                                      average

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

    In addition to the sites listed in the table above, three sites, 
Barret Avenue, Cannons Lane, and Indiana Armory, did not operate for 
the entire three-year period from 2007 to 2009, either because the site 
ended operation before the end of that period or because the site began 
operation after the beginning of that period.
    The first of these three sites, Barret Avenue (site number 21-111-
0048), ended operation at the end of 2008.\1\ Thus, the most recent 
three-year period of data for this site is 2006 to 2008. For this 
period, the Barret Avenue site monitored an average annual 
concentration of 14.1 [micro]g/m\3\, reflecting attainment of the 
standard. The Barret Avenue site has not historically monitored the 
highest concentrations in the area. In addition, the other sites in the 
area, which have continued to operate, are currently attaining the 
standard and are showing decreased concentrations. Thus, EPA believes 
that the standard was and continues to be attained at this site.
---------------------------------------------------------------------------

    \1\ In letters dated November 4, 2008, and January 28, 2009, to 
the Louisville Metro Air Pollution Control District, EPA approved 
the District's request to terminate the operation of the Barret 
Avenue monitor for safety reasons, and to establish a new monitor 
starting operation January 1, 2009, at the Cannons Lane site, 
approximately 4 miles away.
---------------------------------------------------------------------------

    More generally, EPA believes that the Louisville area has a 
sufficient network of sites collecting complete data showing attainment 
to conclude that the Louisville area is now meeting the annual 
PM<INF>2.5</INF> NAAQS.
    Following discontinuation of the Barret Avenue site, two new sites 
began operation. The Indiana Armory site (site number 18-019-0008) 
began operation in the third quarter of 2008, and the Cannons Lane site 
(site number 21-111-0067) began operation at the beginning of 2009. 
These two sites started operation after 2007 and thus have not yet 
collected three years of data. Nevertheless, EPA examined the data at 
these sites to consider whether these data are consistent with the 
findings discussed above that were derived for sites with a complete 
three-year set of data for the 2007-2009 period.
    An examination of data from these two sites (as well as an 
examination of data at the Barret Avenue site) is provided in a 
memorandum (available in the docket for this proposed rulemaking) dated 
June 22, 2010. The Indiana Armory site monitored an average 
concentration in the second half of 2008 of 13.4 [micro]g/m\3\, and an 
annual average concentration in 2009 of 10.8 [micro]g/m\3\. The Cannons 
Lane site for 2009 monitored an annual average concentration of 11.7 
[micro]g/m\3\. All of these values are below the standard.
    Since few data are available for 2010, the 2007 to 2009 data 
represent the most recent available data for EPA to use in its 
assessment. On the basis of this review, EPA is proposing to determine 
that the Louisville area has attained the 1997 annual PM<INF>2.5</INF> 
NAAQS.
    EPA is soliciting public comments on its proposal to determine that 
the Louisville area has attained the 1997 annual PM<INF>2.5</INF> 
NAAQS.

IV. What is the effect of this action?

    If this proposed determination is made final, the requirements for 
the Louisville PM<INF>2.5</INF> nonattainment 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 PM<INF>2.5</INF> NAAQS would be suspended for so long as the 
area continues to attain the PM<INF>2.5</INF> NAAQS. See 40 CFR 
51.1004(c). Notably, as described below, any such determination would 
not be equivalent to the redesignation of the area to attainment for 
the annual PM<INF>2.5</INF> NAAQS.
    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 PM<INF>2.5</INF> NAAQS, 
the basis for the suspension of the specific requirements would no 
longer exist for the Louisville nonattainment 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 PM<INF>2.5</INF>

[[Page 55728]]

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 Louisville area would remain nonattainment for the 1997 annual 
PM<INF>2.5</INF> 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 that the Louisville 
area has attained the 1997 annual PM<INF>2.5</INF> NAAQS. Today's 
action does not address the 24-hour PM<INF>2.5</INF> NAAQS.
    If the Louisville area continues to monitor attainment of the 
annual PM<INF>2.5</INF> NAAQS, the requirements for the Louisville 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 PM<INF>2.5</INF> NAAQS will remain suspended.

V. Statutory and Executive Order Reviews

    Under Executive Order 12866 (58 FR 51735, October 4, 1993), this 
proposed action is not a ``significant regulatory action'' and 
therefore is not subject to review by the Office of Management and 
Budget. For this reason, this action is not subject to Executive Order 
13211, ``Actions Concerning Regulations That Significantly Affect 
Energy Supply, Distribution, or Use'' (66 FR 28355, May 22, 2001). This 
action proposes to make a determination based on air quality data and 
would, if finalized, result in the suspension of certain Federal 
requirements. Accordingly, the Administrator certifies that this rule 
will not have a significant economic impact on a substantial number of 
small entities under the Regulatory Flexibility Act (5 U.S.C 601 et 
seq.). Because this rule proposes to make a determination based on air 
quality data, and would, if finalized, result in the suspension of 
certain Federal requirements, it 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).
    This proposed rule also does not have tribal applications because 
it will not have a substantial direct effect on one or more Indian 
tribes, on the relationship between the Federal Government and Indian 
tribes, or on the distribution of power and responsibilities between 
the Federal Government and Indian tribes, as specified by Executive 
Order 13175 (65 FR 67249, November 9, 2000). This proposed action also 
does not have Federalism implications because it does not have 
substantial direct effects on the States, on the relationship between 
the national government and the States, or on the distribution of power 
and responsibilities among the various levels of government, as 
specified in Executive Order 13132 (64 FR 43255, August 10, 1999), 
because it merely proposes to make a determination based on air quality 
data and would, if finalized, result in the suspension of certain 
Federal requirements, and does not alter the relationship or the 
distribution of power and responsibilities established in the CAA. This 
proposed rule also is not subject to Executive Order 13045 ``Protection 
of Children from Environmental Health Risks'' (62 FR 19885, April 23, 
1997) because it proposes to determine that air quality in the affected 
area is meeting Federal standards.
    The requirements of 12(d) of the National Technology Transfer and 
Advancement Act of 1995 (15 U.S.C. 272 note) do not apply because it 
would be inconsistent with applicable law for EPA, when determining the 
attainment status of an area, to use voluntary consensus standards in 
place of promulgated air quality standards and monitoring procedures to 
otherwise satisfy the provisions of the CAA. This proposed rule does 
not impose an information collection burden under the provisions of the 
Paper Reduction Act of 1995 (44 U.S.C. 3501 et seq.).
    Under Executive Order 12898, EPA finds that this rule, pertaining 
to the determination of attainment of the fine particle standard for 
the bi-state Louisville (Indiana and Kentucky) area, involves proposed 
determinations of attainment based on air quality data and will not 
have disproportionately high and adverse human health or environmental 
effects on any communities in the area, including minority and low-
income communities.
