Air Plan Approval; Illinois; Redesignation of the Lemont and 
Pekin Sulfur Dioxide Nonattainment Areas

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: In accordance with the Clean Air Act (CAA), the Environmental 
Protection Agency (EPA) is proposing to redesignate the Lemont and 
Pekin sulfur dioxide (SO2) nonattainment areas from 
nonattainment to attainment. EPA is also proposing to approve Illinois' 
maintenance plans for these two areas. Emissions of SO2 in 
the areas have been reduced, and the air quality in the two areas is 
currently better than the SO2 national ambient air quality 
standard (NAAQS).

I. Background and Redesignation Requirements

    In 2010, EPA established a revised primary SO2 NAAQS of 
75 parts per billion (ppb) (75 FR 35520, June 22, 2010). EPA designated 
the Lemont and Pekin areas as nonattainment for the 2010 SO2 
NAAQS on August 5, 2013 (78 FR 47191) based upon air quality monitoring 
data for calendar years 2009-2011. The Lemont nonattainment area is 
comprised of Lemont Township in Cook County and Lockport and DuPage 
Townships in Will County, Illinois. The Pekin nonattainment area is 
comprised of Hollis Township in Peoria County and Cincinnati and Pekin 
Townships in Tazewell County, Illinois.
    On March 2, 2016, Illinois submitted nonattainment State 
Implementation Plans (SIPs) to provide for attainment of the NAAQS in 
the Lemont and Pekin nonattainment areas by the SO2 
attainment date of October 4, 2018. The plans were developed to meet 
the additional requirements of sections 172(c) and 191-192 of the CAA. 
Illinois supplemented the plans on August 8,

[[Page 10361]]

2016 and May 4, 2017, and EPA approved them on February 1, 2018 (83 FR 
4591). Illinois submitted its request to redesignate the Lemont and 
Pekin areas on May 24, 2019.
    Under CAA section 107(d)(3)(E), there are five criteria which must 
be met before a nonattainment area may be redesignated to attainment:
    1. EPA has determined that the relevant NAAQS has been attained in 
the area.
    2. The applicable implementation plan has been fully approved by 
EPA under section 110(k) of the CAA.
    3. EPA has determined that improvement in air quality is due to 
permanent and enforceable reductions in emissions resulting from the 
SIP, applicable Federal regulations, and other permanent and 
enforceable reductions.
    4. EPA has fully approved a maintenance plan, including a 
contingency plan, for the area under section 175A of the CAA.
    5. The State has met all applicable requirements for the area under 
section 110 and part D of the CAA.

II. Determination of Attainment

    The first requirement for redesignation is to demonstrate that the 
NAAQS has been attained in the area. Under EPA regulations at 40 CFR 
part 50, the SO2 NAAQS is met at an ambient air quality 
monitoring site when the three-year average of the annual 99th 
percentile daily maximum one-hour average concentration values for the 
site is less than or equal to 75 ppb, as determined in accordance with 
appendix T of 40 CFR part 50. As stated in EPA's April 2014 ``Guidance 
for 1-Hour SO2 Nonattainment Area SIP Submissions'' (April 
2014 Guidance), there are two components needed to support an 
attainment determination for SO2: An initial review of 
representative air quality monitoring data, then a further analysis, 
which generally requires air quality modeling, to demonstrate that the 
entire area is attaining the applicable NAAQS, based on current actual 
emissions or the fully implemented control strategy. Illinois has 
addressed both components for each nonattainment area.

a. Lemont

    EPA has reviewed the ambient air monitoring data for the Lemont 
nonattainment area. There is one SO2 monitoring site in Cook 
County for the Lemont area (monitor 17-031-1601 in Lemont Township). 
The data from this monitor have been certified and recorded in EPA's 
Air Quality System database. Illinois has committed to continue 
monitoring for SO2 at this location. EPA's review addresses 
air quality data collected through 2018, which includes the most recent 
three years of complete, quality-assured data.
    Table 1 shows the 99th percentile results and three-year average 
design values for the Lemont nonattainment area monitors for 2012-2018. 
Lemont has been in attainment of the 2010 SO2 NAAQS of 75 
ppb since the 2012-2014 three-year design value period, when the design 
value was 66 ppb. Currently, the design value at the Lemont monitor has 
dropped to 8 ppb (2016-2018). Therefore, Illinois has demonstrated that 
the Lemont area's SO2 monitor shows attainment of the 2010 
SO2 NAAQS. Preliminary monitoring data for 2019 indicate 
that the area is continuing to attain the 2010 SO2 NAAQS.

                                                       Table 1--Lemont Monitoring Data, 2012-2018

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

    Illinois also prepared a dispersion modeling analysis demonstrating 
that the Lemont area will attain the SO2 NAAQS under the 
area's control strategy. Illinois provided this analysis in its March 
2, 2016 nonattainment SIP submittal. Illinois' analysis showed that 
revised SO2 emission limits at five SO2 sources 
in the Lemont nonattainment area, in addition to statewide requirements 
for lower sulfur fuel oil, will provide for attainment. Illinois has 
confirmed that the modeled facilities are currently in full compliance 
with their emission limits. Current actual emissions at these 
facilities are therefore at or below the levels Illinois used in its 
modeling analysis. The modeling analysis was discussed in detail in the 
October 5, 2017 (82 FR 46434) notice of proposed rulemaking for the 
Lemont and Pekin SO2 nonattainment SIPs. The modeling shows 
that compliance with the emission limits in Illinois' plan, even at 
maximum allowable emissions, yields attainment in the entire Lemont 
area. Further, since the sources in the Lemont area are complying with 
these limits, this modeling supports EPA's proposed conclusion that the 
Lemont area is attaining the SO2 NAAQS.

b. Pekin

    EPA has reviewed the ambient air monitoring data for the Pekin 
nonattainment area. There is one SO2 monitoring site in 
Tazewell County for the Pekin area (17-179-0004, in Pekin Township). 
The initial SO2 data gathered between August 31, 2016 and 
August 16, 2018 was invalidated after the monitor failed an audit in 
late 2018. Illinois addressed EPA's concerns with the monitor by 
replacing faulty equipment at the site on August 16, 2018. EPA is 
satisfied that Illinois is meeting the requirements of 40 CFR part 58, 
appendix A for this monitor, and that the SO2 data gathered 
at this monitor after August 16, 2018 has been valid.
    Because portions of the data from 2016 to 2018 were invalidated, 
there is no valid three-year design value for SO2 at Pekin 
from the 2014-2016 time period to the present. The last valid three-
year design value which was calculated using data gathered before the 
audit and data invalidation for Pekin was 167 ppb (2013-2015), which 
does not meet the 2010 SO2 NAAQS. The 2013-2015 design value 
does not provide useful information on the current state of 
SO2 air quality in Pekin, because it represents the local 
air

[[Page 10362]]

quality before Illinois' revised SO2 nonattainment SIP 
limits for Pekin came into effect. SO2 emissions in the area 
decreased after 2015 due to the revised SIP emission limits at three 
facilities: The Midwest Generation Powerton Station, the Illinois Power 
Holdings E.D. Edwards Power Plant, and Aventine Renewable Energy 
Resources, now Pacific Ethanol Pekin, Inc. Since January 1, 2017, the 
Pekin facilities have been in full compliance with their new emission 
limits. Air quality monitoring data measured from late 2018 to the 
present, confirmed to be valid, now indicates that emissions have 
sharply declined since 2015 and remain well below the 2010 
SO2 NAAQS for 2019. The 99th percentile one-hour maximum 
value for the valid portion of 2018 is 12 ppb. The preliminary data for 
2019 indicates a 99th percentile one-hour maximum value of 17 ppb. The 
average of preliminary valid data for 2018-2019 is 15 ppb. While the 
available valid data from August 2018 to the present is not enough to 
calculate a valid three-year design value to confirm that the NAAQS are 
met, the available valid data indicates that ambient air concentrations 
of SO2 at Pekin have substantially decreased to a level 
below the 2010 SO2 NAAQS. This supports EPA's proposed 
conclusion that the Pekin area is attaining the standard and is 
eligible for redesignation.
    Because the Pekin monitor cannot be used to fully demonstrate 
attainment of the 2010 SO2 NAAQS until three years of valid 
data have been gathered, Illinois' redesignation request for the Pekin 
nonattainment area relied upon the demonstration of attainment based on 
air dispersion modeling which Illinois submitted to EPA as part of its 
March 2016 nonattainment SIP submittal. As noted in EPA's April 2014 
Guidance, for a short-term (i.e., 1-hour) standard, the EPA believes 
that dispersion modeling, using allowable emissions and addressing 
stationary sources in the affected area (and in some cases, those 
sources located outside the nonattainment area which may affect 
attainment in the area) is technically appropriate, efficient and 
effective in demonstrating attainment in nonattainment areas, because 
it takes into consideration combinations of meteorological and emission 
source operating conditions that can contribute to peak ground-level 
concentrations of SO2.
    Illinois' modeled demonstration of attainment for the Pekin area 
was discussed in detail in EPA's proposed approval of the Pekin 
SO2 nonattainment plan. See 82 FR 46438, October 5, 2017. 
Illinois' analysis showed that revised SO2 emission limits 
at three facilities in the Pekin nonattainment area, in addition to 
statewide requirements for lower sulfur fuel oil, will provide for 
attainment. The modeled demonstration included the three Pekin sources 
at their revised SO2 emission limits and emissions from all 
other major SO2 sources within 50 kilometers of the Pekin 
nonattainment area, modeled at their maximum allowable SO2 
emission rates. Illinois' analysis demonstrated that the Pekin area 
will attain and maintain the 2010 SO2 NAAQS at the maximum 
allowable emission level. The Pekin sources were required to comply 
with their revised SIP emission limits by January 1, 2017. Illinois has 
confirmed that they are in full compliance with their emission limits. 
Current actual emissions at these facilities are therefore at or below 
the emission rates which Illinois used in its modeling analysis. Since 
the Pekin modeled attainment demonstration shows that compliance with 
the emission limits in Illinois' plan even at maximum allowable 
emissions yields attainment in the entire Pekin nonattainment area, and 
since the sources are complying with these limits, Illinois' modeled 
attainment demonstration supports EPA's proposed conclusion that the 
Pekin area is currently attaining and will continue to attain the 
SO2 NAAQS.
    EPA proposes to conclude that, considered together, the modeling 
and monitoring data currently available for the Pekin area are adequate 
to address the redesignation requirement to demonstrate attainment of 
the 2010 SO2 NAAQS, and that both the results of the modeled 
attainment demonstration, based on current enforceable emission limits, 
and the currently available valid monitoring data for Pekin indicate 
that the Pekin area is attaining the 2010 SO2 NAAQS.

III. Approval of Illinois' SIPs

    On February 1, 2018 (83 FR 4591), EPA approved Illinois' 
nonattainment SIPs for the Lemont and Pekin nonattainment areas, 
including emission limits which were demonstrated to provide for 
attainment in both areas. In that action, EPA found that Illinois had 
satisfied the requirements for providing for attainment of the 
SO2 NAAQS in the Lemont and Pekin nonattainment area. 
Illinois has adopted SO2 SIP regulations requiring emission 
reductions for sources in the Lemont and Pekin nonattainment areas. 
Illinois maintains an active enforcement program to ensure ongoing 
compliance in both areas. Illinois' new source review/prevention of 
significant deterioration program will address emissions from new 
sources in both areas. Therefore, EPA proposes to conclude that this 
redesignation criterion has been met by Illinois for both areas.

IV. Permanent and Enforceable Emission Reductions

    For an area to be redesignated, the state must be able to 
reasonably attribute the improvement in air quality to emission 
reductions which are permanent and enforceable. In the Lemont 
nonattainment area, Illinois applied revised emission limits to Owens 
Corning Roofing & Asphalt in Summit, Ingredion Bedford Park in Bedford 
Park, Oxbow Midwest Calcining in Lemont, the Midwest Generation Joliet 
Generating Station in Joliet, and the Midwest Generation Will County 
Generating Station in Romeoville. Total facility SO2 
emissions in the Lemont nonattainment area have decreased by over 5,000 
tons per year (tpy). In the Pekin nonattainment area, Illinois applied 
revised emission limits to the Midwest Generation Powerton Station in 
Pekin, the Illinois Power Holdings E.D. Edwards Power Plant in 
Bartonville, and the Aventine Renewable Energy Resources ethanol 
facility, now Pacific Ethanol Pekin, Inc., located in Pekin. Total 
facility SO2 emissions in the Pekin nonattainment area were 
reduced by over 21,000 tpy. These emission reductions have been made 
permanent and enforceable by the limits that Illinois adopted into 
Title 35, part 214 of the Illinois Administrative Code, which EPA 
approved into the SIP. See 83 FR 4591, February 1, 2018. EPA has 
approved Illinois' SO2 SIP rules, which makes them federally 
enforceable.
    Recent monitoring data indicate that ambient SO2 levels 
have improved significantly in the Lemont and Pekin nonattainment 
areas. At the time that the areas were designated nonattainment, the 
2009-2011 monitored design value in the Lemont area was 98 ppb, and the 
2009-2011 monitored design value at the Pekin monitor was 211 ppb. 
After the new SIP emission limits came into effect in 2017, the 
monitored SO2 design value for Lemont dropped to 8 ppb 
(2016-2018), which is well below the SO2 NAAQS of 75 ppb. 
The monitored SO2 values at the Pekin monitor also dropped 
after the new SIP emission limits came into effect, to less than 20 ppb 
in 2018 and 2019 (based on estimated 99th percentile annual maximum 1-
hour values from valid data; see discussion in III.b. above). EPA 
proposes to find that the improvement in air quality in the

[[Page 10363]]

Lemont and Pekin nonattainment areas can be attributed to the permanent 
and enforceable emission reductions in Illinois' approved nonattainment 
SIPs.

V. Maintenance Plans

    CAA section 175A sets forth the elements of a maintenance plan for 
areas seeking redesignation from nonattainment to attainment. Under 
section 175A, the plan must demonstrate continued attainment of the 
applicable NAAQS for at least ten years after the nonattainment area is 
redesignated to attainment. Eight years after the redesignation, the 
state must submit a revised maintenance plan demonstrating that 
attainment will continue to be maintained for the ten years following 
the initial ten-year period. To address the possibility of future NAAQS 
violations, the maintenance plan must contain contingency measures as 
EPA deems necessary to assure prompt correction of any future one-hour 
violations. Specifically, the maintenance plan should address five 
requirements: The attainment emissions inventory, maintenance 
demonstration, monitoring, verification of continued attainment, and a 
contingency plan.
    Illinois' May 24, 2019 redesignation request contains its 
maintenance plans for Lemont and Pekin, which Illinois has committed to 
review and update eight years after redesignation.
    Illinois projected SO2 emissions for an interim future 
year, 2023, and for the maintenance year, 2030, for both areas. 
Illinois projected that total SO2 emissions in the Lemont 
nonattainment area in the maintenance year would drop from 10,975 tpy 
in 2014 to 824 tpy in 2030, considering both the SIP reductions and 
projected future growth. Illinois projected that total SO2 
emissions in the Pekin nonattainment area in the maintenance year would 
drop from 32,331 tpy in 2014 to 10,588 tpy in 2030, considering both 
the SIP reductions and projected future growth.
    Illinois' maintenance demonstration consists of the nonattainment 
SIP air quality analyses which demonstrated that the emission 
reductions in effect in the Lemont and Pekin nonattainment areas will 
provide for attainment of the SO2 NAAQS. The permanent and 
enforceable SO2 emission limits in Illinois' SO2 
SIP ensure that the SO2 emissions in the Lemont and Pekin 
areas will be equal to or less than the emission levels which were 
evaluated in the air quality analyses, and Illinois' enforcement 
program will ensure that the Lemont and Pekin SO2 emission 
limits are met continuously.
    For continued verification, Illinois has committed to track the 
SO2 emissions and compliance status of the facilities in the 
Lemont and Pekin areas. The state commits to update its emissions 
inventories as required by EPA. Illinois has also committed to continue 
ambient SO2 monitoring at Lemont and Pekin to verify 
attainment of the SO2 NAAQS.
    The requirement to submit contingency measures in accordance with 
CAA section 172(c)(9) can be adequately addressed for SO2 by 
the operation of a comprehensive enforcement program which can quickly 
identify and address sources that might be causing exceedances of the 
NAAQS level. Illinois' enforcement program is active and capable of 
prompt action to remedy compliance issues or NAAQS exceedances. 
Illinois' redesignation request discusses the state's plan to respond 
to increased SO2 emissions or ambient monitored 
concentrations or new exceedances of the SO2 NAAQS in the 
maintenance areas. Illinois commits to evaluate air quality and 
emission trends, identify areas of concern, and take action as needed, 
particularly if a violation is recorded, or an annual average 99th 
percentile maximum daily one-hour SO2 concentration of 75 
ppb or greater occurs, or if total SO2 emissions increase 
more than five percent above the attainment year inventory. Illinois 
has the authority to expeditiously adopt, implement and enforce any 
subsequent emissions control measures deemed necessary to correct any 
future SO2 violations. Illinois commits to adopt and 
implement such corrective actions as necessary. The public will have 
the opportunity to participate in the contingency measure 
implementation process.
    Based on the above, EPA proposes to find that Illinois has 
addressed the contingency measure requirement for both areas. Further, 
EPA proposes to find that Illinois' maintenance plans adequately 
address the five basic components necessary to maintain the 
SO2 NAAQS in the Lemont and Pekin nonattainment areas.

VI. Requirements for the Areas Under Section 110 and Part D

    Illinois has submitted information demonstrating that it meets all 
requirements of the CAA applicable to the Lemont and Pekin 
nonattainment areas. EPA approved Illinois' infrastructure SIP for 
SO2 on October 16, 2014 (79 FR 62042). This infrastructure 
SIP approval confirms that Illinois's SIP meets the requirements of CAA 
section 110(a)(1) and 110(a)(2) to contain the basic program elements, 
such as an active enforcement program and permitting program. The 
program elements addressed in the infrastructure SIP will be 
implemented and enforced in the Lemont and Pekin areas.
    Section 191 of the CAA requires Illinois to submit part D SIPs for 
the Lemont and Pekin nonattainment areas by April 4, 2015. As discussed 
earlier, Illinois submitted its part D SIPs for the two areas on March 
2, 2016 and supplemented them on August 8, 2016 and May 4, 2017. The 
SIPs each included a demonstration of attainment and revised 
SO2 emission limits. EPA approved the Lemont and Pekin SIPs 
on February 1, 2018 (83 FR 4591). In its rulemaking, EPA determined 
that Illinois had satisfied the various requirements under CAA section 
110 and part D for the Lemont and Pekin nonattainment areas, such as 
the requirements for an attainment inventory of the SO2 
emissions from sources in each nonattainment area (required under CAA 
section 173(c)(3)), reasonably available control measures (required 
under CAA section 173(c)(1)), and reasonable further progress (required 
under CAA section 173(c)(2)).
    Section 176(c) of the CAA requires states to establish criteria and 
procedures to ensure that federally supported or funded projects 
conform to the air quality planning goals in the applicable SIP. The 
requirement to determine conformity applies to transportation plans, 
programs, and projects that are developed, funded, or approved under 
title 23 of the United States Code and the Federal Transit Act 
(transportation conformity) as well as to all other federally supported 
or funded projects (general conformity). State transportation 
conformity SIP revisions must be consistent with Federal conformity 
regulations relating to consultation, enforcement, and enforceability 
that EPA promulgated pursuant to its authority under the CAA. EPA 
approved Illinois' transportation conformity SIPs on December 23, 1997 
(62 FR 67000). In April 2010, EPA promulgated changes to 40 CFR 51.851, 
eliminating the requirement for states to maintain a general conformity 
SIP. Illinois has met the applicable conformity requirements under CAA 
section 176.
    Based on the above, EPA is proposing to find that Illinois has 
satisfied all requirements applicable to the Lemont and Pekin areas 
under section 110 and part D of title I of the CAA.

VII. What action is EPA taking?

    In accordance with Illinois' May 24, 2019 request, EPA is proposing 
to

[[Page 10364]]

redesignate the Lemont and Pekin SO2 areas from 
nonattainment to attainment of the SO2 NAAQS. Illinois has 
demonstrated, among other things, that these areas are attaining the 
SO2 NAAQS, and that the improvement in air quality is due to 
permanent and enforceable SO2 emission reductions in the 
nonattainment area. EPA is also proposing to approve Illinois' 
maintenance plans, which are designed to ensure that the Lemont and 
Pekin nonattainment areas will continue to maintain the SO2 
NAAQS.

VIII. Statutory and Executive Order Reviews

    Under the CAA, redesignation of an area to attainment and the 
accompanying approval of a maintenance plan under section 107(d)(3)(E) 
are actions that affect the status of a geographical area and do not 
impose any additional regulatory requirements on sources beyond those 
imposed by state law. A redesignation to attainment does not in and of 
itself create any new requirements, but rather results in the 
applicability of requirements contained in the CAA for areas that have 
been redesignated to attainment. Moreover, 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:
