40 CFR Part 52
[EPA-R05-OAR-2009-0512; FRL-8962-1]
Determination of Attainment, Approval and Promulgation of Air
Quality Implementation Plans; Indiana
AGENCY: Environmental Protection Agency (EPA).
ACTION: Proposed rule.
-----------------------------------------------------------------------
SUMMARY: EPA is proposing to make a determination, under the Clean Air
Act (CAA), that the Chicago-Gary-Lake County, Illinois-Indiana (IL-IN)
ozone nonattainment area has attained the 1997 eight-hour ozone
National Ambient Air Quality Standard (NAAQS). This determination is
based on complete, quality-assured ambient air quality monitoring data
for the period of 2006-2008. Preliminary data for 2009 show that the
area continues to attain the standard. EPA is also proposing to approve
a request from the State of Indiana to exempt sources of Nitrogen
Oxides (NOX) in Lake and Porter Counties from CAA
requirements for Reasonably Available Control Technology (RACT). The
State's NOX RACT waiver request is based on the most recent
three years of complete, quality-assured ozone monitoring data, which
demonstrate that additional reduction of NOX emissions would
not contribute to attainment of the 1997 eight-hour ozone NAAQS in the
Chicago-Gary-Lake County, IL-IN area. This action proposes to approve
the State's request for a waiver from the NOX RACT
requirements for Lake and Porter Counties under the CAA. In the Final
Rules section of this Federal Register, EPA is deferring the imposition
of sanctions for the State's failure to submit required NOX
RACT regulations based on this proposed attainment determination while
we complete action on the proposed NOX RACT waiver. This
deferral of sanctions will continue unless EPA determines that the area
is no longer attaining the 1997 eight-hour ozone NAAQS. However, if EPA
proposes and takes final action in the future to redesignate the area
to attainment, such action will permanently stop the sanctions clock.

II. What Is the Background for This Action?
EPA has determined that ground-level ozone (O3) is
detrimental to human health. On July 18, 1997 (62 FR 38856), EPA
promulgated an eight-hour ozone NAAQS of 0.08 parts per million parts
of air (0.08 ppm). This standard is violated in an area when any ozone
monitor in the area (or in its downwind environs) records eight-hour
ozone concentrations with a three-year average of the annual fourth-
highest daily maximum eight-hour ozone concentrations equaling or
exceeding 85 parts per billion parts of air (ppb).
Section 107 of the CAA required EPA to designate as nonattainment
any area that violated the 1997 eight-hour ozone standard. The Federal
Register notice promulgating the eight-hour ozone designations and
classifications was published on April 30, 2004 (69 FR 23857). In that
EPA rulemaking, the Chicago-Gary-Lake County, IL-IN area, which
contains Lake and Porter Counties, Indiana, was designated as a
nonattainment area for the 1997 eight-hour ozone standard, and the
designation became effective on June 15, 2004.
Ground-level ozone is not generally emitted directly by sources.
Rather, emitted NOX and Volatile Organic Compounds (VOC)
react in the presence of sunlight to form ground-level ozone as a
secondary compound, along with other secondary compounds.
NOX and VOC are referred to as ``ozone precursors.''
Reduction of peak ground-level ozone concentrations is achieved through
controlling VOC and NOX emissions.
The CAA, title 1, part D contains two sets of provisions--subparts
1 and 2--that address planning and emission control requirements for
ozone nonattainment areas. Subpart 1 contains general, less
prescriptive requirements for all nonattainment areas of any pollutant
governed by a NAAQS. Subpart 2 contains more specific requirements for
certain ozone nonattainment areas and applies to ozone nonattainment
areas classified under section 181 of the CAA. The Chicago-Gary-Lake
County, IL-IN area is classified as a moderate nonattainment area for
the 1997 eight-hour ozone standard.
The subpart 2 ozone plan requirements under the CAA with respect to
control of VOC and NOX emissions depend on the ozone
nonattainment classification of an area. The air quality planning
requirements for the reduction of NOX emissions are set
forth in section 182(f) of the CAA. Section 182(f) requires States with
areas designated nonattainment for ozone and classified as moderate and
above to adopt and implement the same level of NOX emission
controls for major stationary sources as apply to major stationary
sources of VOC emissions. Section 182(f) also provides that these
NOX emission reduction requirements do not apply to an area
outside of an ozone transport region if EPA determines that additional
reductions of NOX emissions would not contribute to
attainment of the ozone standard in the area. Section 182(f)(1)(A). In
areas where the ozone standard is attained, as demonstrated by
complete, quality-assured air quality data, without the implementation
of the additional section 182(f) NOX emission controls, it
is clear that the additional NOX emission reductions
required by section 182(f) did not contribute to attainment of the
ozone standard.
On March 17, 2008, EPA notified Thomas W. Easterly, Commissioner,
Indiana Department of Environmental Management (IDEM), that EPA had
determined that the State of Indiana had failed to submit a
NOX RACT State Implementation Plan (SIP) revision for Lake
and Porter Counties (the Indiana portion of the Chicago-Gary-Lake
County, IL-IN ozone nonattainment area for the 1997 eight-hour ozone
standard). EPA formalized this finding in the Federal Register on March
24, 2008 (73 FR 15416), and that action commenced the sanctions process
outlined by section 179 of the CAA and 40 CFR 52.31. See 59 FR 39832,
August 4, 1994. Under this process, the new source two-to-one (2:1)
emissions offset sanction would take effect in Lake and Porter Counties
on September 24, 2009. The sanctions clock would run and any imposed
sanctions would remain in effect until either a NOX RACT SIP
revision is submitted to EPA by the State of Indiana and is
affirmatively determined complete by EPA or a NOX control
exemption (waiver) under section 182(f) is granted by EPA. In the Final
Rules section of today's Federal Register, EPA has published an interim
final rule to defer sanctions for Lake and Porter Counties based on our
proposed determination that the Counties are attaining the 1997 eight-
hour ozone NAAQS and that the NOX RACT waiver request is
approvable.
The criteria established for determining the applicability of
section 182(f) NOX emission controls and the evaluation of
section 182(f) NOX emission control waiver requests are set
forth in a January 14, 2005, EPA policy memorandum, ``Guidance on
Limiting Nitrogen Oxides (NOX) Requirements Related to 8-
Hour Ozone Implementation,'' from Stephen D. Page, Director, Office of
Air Quality Planning and Standards.
III. State Petition
On June 5, 2009, IDEM submitted a request for the redesignation of
Lake and Porter Counties to attainment of the 1997 eight-hour ozone
standard. As part of this ozone redesignation request, IDEM also
requested an exemption from NOX RACT requirements for Lake
and Porter Counties under section 182(f) of the CAA based on the
monitoring of ozone, which showed attainment of the 1997 eight-hour
ozone standard in the Chicago-Gary-Lake County, IL-IN ozone
nonattainment area and at the Chiwaukee Prairie monitoring site in
Kenosha County, Wisconsin monitoring site.\1\ The NOX
exemption request is based on ozone air quality monitoring data for the
period of 2006-2008, which demonstrate that the 1997 eight-hour ozone
NAAQS has been attained in the area without additional reductions of
NOX emissions.
---------------------------------------------------------------------------
\1\ Although the Chiwaukee Prairie monitoring site is outside of
the Chicago-Gary-Lake County, IL-IN ozone nonattainment area, it is
very near the Illinois-Wisconsin border and is considered to be a
peak ozone impact site for VOC and NOX emissions
originating in the Chicago-Gary-Lake County, IL-IN ozone
nonattainment area. The fact that the Chiwaukee Prairie ozone
monitoring site is the ozone design value site for the Chicago-Gary-
Lake County, IL-IN eight-hour ozone nonattainment area is documented
in an enclosure to a December 3, 2003 letter from Thomas V. Skinner,
Regional Administrator, Region 5, U.S. Environmental Protection
Agency to Honorable Rod R. Blagojevich, Governor, State of Illinois.
---------------------------------------------------------------------------
IV. EPA Analysis of the Petition
A. Has the Chicago-Gary-Lake County, IL-IN Area Attained the 1997
Eight-Hour Ozone NAAQS?
An area may be considered to be attaining the 1997 eight-hour ozone
standard if there are no violations of the standard, as determined in
accordance with 40 CFR 50.10 and appendix I, based on the most recent
three complete, consecutive calendar years of quality-assured air
quality monitoring data at all ozone monitoring sites in the area and
in its nearby downwind environs. To attain this standard, the average
of the annual fourth-high daily
[[Page 48705]]
maximum eight-hour average ozone concentrations measured and recorded
at each monitoring site (the monitoring site's ozone design value) over
the most recent three-year period must not exceed the ozone standard.
Based on an ozone data rounding convention described in 40 CFR 50,
appendix I, the eight-hour ozone standard is attained if the area's
ozone design value \2\ is 0.084 ppm or less. The data must be collected
and quality-assured in accordance with 40 CFR 58, and must be recorded
in EPA's Air Quality System (AQS). The ozone monitors generally should
have remained at the same locations for the duration of the monitoring
period required to demonstrate attainment (for three years or more).
The data supporting attainment of the standard must be complete in
accordance with 40 CFR 50, appendix I.
---------------------------------------------------------------------------
\2\ The worst-case monitoring site-specific ozone design value
in the area and in its downwind environs.
---------------------------------------------------------------------------
As part of the June 5, 2009, ozone redesignation request, IDEM
summarized the annual fourth-high eight-hour ozone concentrations and
the three-year eight-hour ozone design values for the period of 2003-
2008 for all ozone monitoring sites in Lake and Porter Counties and in
the Chicago-Gary-Lake County, IL-IN ozone nonattainment area. This
summary also includes ozone concentration data for the Chiwaukee
Prairie monitoring site in Wisconsin. IDEM notes that the 2006-2008
ozone design values for all monitoring sites are below the 0.084 ppm
ozone attainment level. We have reviewed the data and agree that the
ozone monitoring data for the monitoring sites in the nonattainment
area and for the Chiwaukee Prairie, Wisconsin monitoring site show
attainment of the 1997 eight-hour ozone standard. The worst-case 2006-
2008 ozone design \3\ for the Chicago-Gary-Lake County, IL-IN area is
found at the Chiwaukee Prairie monitoring site, with a value of 0.078
ppm, below the 0.08 ppm eight-hour ozone standard level. See Table 1
below.
---------------------------------------------------------------------------
\3\ For an individual ozone monitoring site, the ozone design
value is the three-year average of the annual fourth-highest daily
maximum eight-hour ozone concentrations. For any given area, the
area's ozone design value is the worst-case site-specific ozone
design value for all ozone monitoring sites in the area.
---------------------------------------------------------------------------
Table 1 summarizes the annual fourth-high daily maximum eight-hour
ozone concentrations and three-year (2006-2008) averages of the annual
fourth-high daily maximum eight-hour ozone concentrations for all ozone
monitoring sites in the Chicago-Gary-Lake County, IL-IN area and for
the Chiwaukee Prairie monitoring site. The 2006-2008 monitoring data
cover the most recent three years of quality assured ozone monitoring
data for this area. These representative peak ozone concentrations are
based on 2006-2008 ozone data that have been quality assured and
certified by the States of Indiana, Illinois, and Wisconsin.

Review of the 2006-2008 ozone concentrations and ozone design
values summarized in Table 1 shows that all of the ozone monitoring
sites for the Chicago-Gary-Lake County, IL-IN area, plus the Chiwaukee
Prairie monitoring site in Wisconsin, were attaining the 1997 eight-
hour ozone standard during this period. Therefore, based on the most
recent three years of quality assured ozone monitoring data, the 1997
eight-hour ozone standard has been
[[Page 48706]]
attained in this area. Preliminary data for 2009 \4\ indicate that the
area continues to attain the standard. Based on these ozone monitoring
data, EPA is proposing here to determine that the Chicago-Gary-Lake
County, IL-IN ozone nonattainment area has attained the 1997 eight-hour
ozone standard.
---------------------------------------------------------------------------
\4\ Quality-assured ozone data for 2009 are generally only
available through June in EPA's Air Quality System for Illinois,
Indiana, and Wisconsin, providing an incomplete picture of the peak
ozone concentrations for all high ozone months in 2009. Nonetheless,
these data, coupled with draft data used to support ozone action
alerts, indicate that no violations of the 1997 eight-hour ozone
NAAQS have been monitored to date in this area in 2009.
---------------------------------------------------------------------------
B. EPA Analysis of the State's NOX RACT Waiver Petition
EPA's 2005 guidance document, ``Guidance on Limiting Nitrogen
Oxides (NOx) Requirements Related to 8-Hour Ozone Implementation,''
sets forth the criteria for demonstrating that further NOX
emission reductions in an ozone nonattainment area will not contribute
to ozone attainment. The guidance provides that three consecutive years
of monitoring data documenting ozone levels attaining the ozone NAAQS
in areas in which a State has not implemented certain NOX
emission controls (see discussion below) is adequate to demonstrate
that the additional NOX emission reductions will not aid in
achieving attainment of the ozone NAAQS. As described in the guidance
document, approval of the NOX emission control exemption is
granted by EPA on a contingent basis. The NOX emission
control exemption continues only as long as the State(s) continues to
monitor attainment of the ozone NAAQS. If, prior to redesignation of
the area to attainment of the ozone NAAQS, the area violates the 1997
eight-hour ozone NAAQS, as defined at 40 CFR 50.10 and appendix I, EPA
will undertake rulemaking to withdraw the NOX RACT emission
control exemption for the area. Upon issuance of a final action
withdrawing the NOX RACT emission control exemption, the
area would once again be subject to the NOX emission control
requirements under section 182(f) of the CAA.
As noted above, IDEM documented the annual fourth-highest daily
maximum eight-hour ozone concentrations during the period of 2006-2008
for all ozone monitors in the Chicago-Gary-Lake County, IL-IN ozone
nonattainment area and for the Chiwaukee Prairie monitoring site in
Kenosha County, Wisconsin in the June 5, 2009, submittal. These data
demonstrate that the 1997 eight-hour ozone NAAQS has been attained in
the Chicago-Gary-Lake County, IL-IN ozone nonattainment area.
Indiana has not adopted or implemented the NOX RACT
emission controls required for Lake and Porter Counties under section
182(f). Based on the most recent ozone air quality data and the absence
of these NOX RACT emission controls, IDEM has requested
exemption from the NOX RACT requirements under section
182(f)(1)(A).
EPA's review of the ozone monitoring data and IDEM's NOX
emission control exemption request shows that Indiana has complied with
the requirements for a NOX RACT exemption under section
182(f) of the CAA consistent with guidelines contained in EPA's January
14, 2005, guidance document. Therefore, EPA proposes to determine that
the State of Indiana qualifies for an exemption from NOX
RACT requirements for Lake and Porter Counties.
V. Sanctions
If EPA takes final action approving IDEM's June 5, 2009,
NOX RACT exemption request, Lake and Porter Counties would
not be subject to the NOX RACT requirement for the duration
of the emission control exemption. Based on our proposed determination
that the area has attained the 1997 eight-hour ozone NAAQS and our
proposed approval of the NOX RACT waiver request, in today's
Federal Register we are separately issuing an interim final
determination that it is more likely than not that the State has
corrected the deficiency. That action will defer the imposition of the
2:1 offset sanction that would take effect on September 24, 2009, and
defer the imposition of the highway funding sanction that would take
effect six months following imposition of the offset sanction. The
imposition of sanctions will continue to be deferred if EPA takes final
action determining that the area has attained the 1997 eight-hour ozone
NAAQS and approves the NOX RACT waiver. The area will not be
permanently relieved of the possibility of sanctions until such time as
EPA approves a redesignation request for the area. If, prior to
redesignation of Lake and Porter Counties to attainment of the 1997
eight-hour ozone NAAQS, the NOX RACT exemption is revoked
due to a monitored violation of the 1997 eight-hour ozone NAAQS
anywhere in the Chicago-Gary-Lake County, IL-IN area or at the
Chiwaukee Prairie monitoring site, the sanctions clock will restart at
the point it stopped and the imposition of sanctions will no longer be
deferred. If Lake and Porter Counties are redesignated to attainment of
the 1997 eight-hour ozone NAAQS through a final rule by the EPA, the
NOX RACT waiver will become permanent and the sanctions
clock will permanently stop, and any imposed sanctions resulting from
Indiana's failure to submit NOX RACT regulations for Lake
and Porter Counties would no longer apply.
VI. What Are the Environmental Effects of This Action?
The section 182(f) NOX RACT exemption is based on a
finding that additional reductions of NOX would not
contribute to attainment of the 1997 eight-hour ozone NAAQS in the
Chicago-Gary-Lake County, IL-IN ozone nonattainment area. This area has
three consecutive years of ozone levels attaining the ozone standard
even though Indiana has not adopted and implemented NOX RACT
in Lake and Porter Counties.
While EPA is proposing to waive the requirements to control
NOX emissions through NOX RACT in Lake and Porter
Counties on the basis that NOX emission reductions would not
contribute to attainment of the ozone NAAQS in the Chicago-Gary-Lake
County, IL-IN area, EPA recognizes that there are other benefits to
controlling NOX emissions. These benefits include reducing
acid deposition, reducing nitrogen deposition in sensitive wetlands,
estuaries, and their watersheds, and mitigating ozone transport to
downwind ozone nonattainment areas. Indiana will continue to be
required to control NOX emissions from certain
NOX sources under other CAA programs, such as the Acid Rain
program in title IV of the CAA, for purposes of achieving these
environmental benefits. This proposed NOX RACT waiver for
Lake and Porter Counties will not affect other existing and pending
NOX emission control requirements for Lake and Porter
Counties needed to achieve these environmental benefits.
In addition, EPA notes that an approval of this waiver request is
solely for purposes of the CAA requirements to meet the 1997 eight-hour
ozone NAAQS. The waiver would not apply for purposes of the ozone NAAQS
promulgated in 2008 (March 27, 2008, 73 FR 16435) or for purposes of
any future ozone NAAQS EPA may promulgate. To the extent section 182(f)
applies in this area for purposes of the 2008 or any future ozone
NAAQS, the State would need to submit a NOX RACT SIP or
would need to demonstrate that a waiver is appropriate for purposes of
that different ozone NAAQS.
[[Page 48707]]
VII. EPA's Proposed Action
Based on complete, quality-assured ozone data for 2006-2008, and
considering 2009 ozone data available to date, EPA is proposing to
determine that the Chicago-Gary-Lake County, IL-IN ozone nonattainment
area is attaining the 1997 eight-hour ozone standard.
EPA is proposing approval of Indiana's request to exempt Lake and
Porter Counties from the section 182(f) NOX RACT
requirement. This proposed approval is based on EPA's review of the
evidence provided by Indiana that the requirements of section
182(f)(1)(A), as elaborated upon in EPA's guidance for section 182(f)
exemptions, have been met for Lake and Porter Counties. In the future,
if EPA determines that a violation of the 1997 eight-hour ozone NAAQS
has occurred in the Chicago-Gary-Lake County, IL-IN area or at the
Chiwaukee Prairie monitoring site in Kenosha County, Wisconsin while
Lake and Porter Counties are designated as nonattainment for the 1997
eight-hour ozone NAAQS, EPA will take action to revoke the exemption.
Final approval of Indiana's NOX RACT exemption request
would continue the deferral of the 2:1 new source offset sanction and
the highway funding sanction that would have applied based on the
finding of failure to submit the NOX RACT regulations issued
by the EPA on March 24, 2009. The deferral would remain in place
contingent upon continued attainment of the 1997 eight-hour ozone NAAQS
in the Chicago-Gary-Lake County, IL-IN area. If EPA approves a
redesignation request for the area for the 1997 eight-hour ozone NAAQS,
the sanctions clock will permanently stop at that time. If EPA
determines that there is a violation of the 1997 eight-hour ozone NAAQS
while Lake and Porter Counties remain designated as nonattainment for
the 1997 eight-hour ozone NAAQS, the NOX RACT waiver will no
longer be applicable as of the effective date of any such determination
by EPA. At that time, the sanctions will no longer be deferred and the
sanctions clock will restart at the point at which it stopped. EPA will
provide notice in the Federal Register of any such waiver revocation
and of the restarting of the sanctions clock.
VIII. Statutory and Executive Order Reviews
Under the CAA, the Administrator is required to approve a SIP
submission that complies with the provisions of the CAA and applicable
Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). Thus, in
reviewing SIP submissions, EPA's role is to approve State choices,
provided that they meet the criteria of the CAA. Accordingly, this
action merely approves State law as meeting Federal requirements and
does not impose additional requirements beyond those imposed by State
law. For that reason, this 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.);
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 rule 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.
