Air Plan Approval; Illinois; Infrastructure SIP Requirements for 
the 2012 PM2.5 NAAQS; Interstate Transport

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: The Environmental Protection Agency (EPA) is proposing to 
approve elements of the State Implementation Plan (SIP) submission from 
the Illinois Environmental Protection Agency (IEPA) regarding the 
infrastructure requirements of section 110 of the Clean Air Act (CAA) 
for the 2012 annual fine particulate matter (PM2.5) National 
Ambient Air Quality Standard (NAAQS or standard). The infrastructure 
requirements are designed to ensure that the structural components of 
each state's air quality management program are adequate to meet the 
state's responsibilities under the CAA. This action pertains 
specifically to infrastructure requirements in the Illinois SIP 
concerning interstate transport provisions.

I. What is the background of this SIP submission?

    This rulemaking addresses a submission from the IEPA dated 
September 29, 2017, which describes its infrastructure SIP for the 2012 
annual PM2.5 NAAQS (78 FR 3086). Specifically, this 
rulemaking addresses the portion of the submission dealing with 
interstate pollution transport under CAA Section 110(a)(2)(D)(i), 
otherwise known as the ``good neighbor'' provision. The requirement for 
states to make a SIP submission of this type arises from Section 
110(a)(1) of the CAA, pursuant to which states must submit ``within 3 
years (or such shorter period as the Administrator may prescribe) after 
the promulgation of a national primary ambient air quality standard (or 
any revision thereof),'' a plan that provides for the ``implementation, 
maintenance, and enforcement'' of such NAAQS. Section 110(a)(2) of the 
CAA includes a list of specific elements that ``each such plan'' 
submission must address. EPA commonly refers to such state plans as 
``infrastructure SIPs.'' State plans must address four requirements of 
the good neighbor provisions (commonly referred to as ``prongs''), 
including:

--Prong 1: Prohibiting any source or other type of emissions activity 
in one state from contributing significantly to nonattainment of the 
NAAQS in another state;
--Prong 2: Prohibiting any source or other type of emissions activity 
in one state from interfering with maintenance of the NAAQS in another 
state;
--Prong 3: Prohibiting any source or other type of emissions activity 
in one state from interfering with measures required to prevent 
significant deterioration (PSD) of air quality in another state; and
--Prong 4: Protecting visibility in another state.

    This rulemaking is evaluating whether Illinois' interstate 
transport provisions in its PM2.5 infrastructure SIP meet 
prongs one and two of the good neighbor requirements of the CAA. Prongs 
three and four will be evaluated in a separate rulemaking.
    EPA has developed a consistent framework for addressing the prong 
one and two interstate transport requirements with respect to the 
PM2.5 NAAQS in several previous Federal rulemakings. The 
four basic steps of that framework include: (1) Identifying downwind 
receptors that are expected to have problems attaining or maintaining 
the NAAQS; (2) identifying which upwind states contribute to these 
identified problems in amounts sufficient to warrant further review and 
analysis; (3) for states identified as contributing to downwind air 
quality problems, identifying upwind emissions reductions necessary to 
prevent an upwind state from significantly contributing to 
nonattainment or interfering with maintenance of the NAAQS downwind; 
and (4) for states that are found to have emissions that significantly 
contribute to nonattainment or interfere with maintenance of the NAAQS 
downwind, reducing the identified upwind emissions through adoption of 
permanent and enforceable measures. This framework was most recently 
applied with respect to PM2.5 in the August 8, 2011 Cross-
State Air Pollution Rule (CSAPR) (76 FR 48208), designed to address 
both the 1997 and 2006 PM2.5 standards, as well as the 1997 
and 2008 ozone standards.

II. What guidance and memoranda is EPA using to evaluate this SIP 
submission?

    EPA highlighted the statutory requirement to submit infrastructure 
SIPs within three years of promulgation of a new NAAQS in an October 2, 
2007 guidance document entitled ``Guidance on SIP Elements Required 
Under Sections 110(a)(1) and (2) for the 1997 8-hour Ozone and 
PM2.5 National Ambient Air Quality Standards.'' EPA has 
issued additional guidance documents and memoranda, including a 
September 13, 2013, guidance document titled ``Guidance on 
Infrastructure State Implementation Plan (SIP) Elements under Clean Air 
Act Sections 110(a)(1) and 110(a)(2).''
    The most recent relevant document is a memorandum published on 
March 17, 2016, titled ``Information on the Interstate Transport `Good 
Neighbor' Provision for the 2012 Fine Particulate Matter National 
Ambient Air Quality Standards under Clean Air Act Section 
110(a)(2)(D)(i)(I)'' (2016 memorandum). The 2016 memorandum describes 
EPA's consistent approach over the years to address interstate 
transport and provides EPA's general review of relevant modeling data 
and air quality projections as they relate to the 2012 annual 
PM2.5 NAAQS. The 2016 memorandum provides information 
relevant to EPA Regional office review of CAA Section 110 
(a)(2)(D)(i)(I) ``good neighbor'' provision in infrastructure SIPs with 
respect to the 2012 annual PM2.5 NAAQS. IEPA's submittal and 
this rulemaking consider information provided in that memorandum.
    The 2016 memorandum provides states and EPA Regional offices with 
future year annual PM2.5 design values for monitors in the 
United States based on quality assured and certified ambient monitoring 
data and air quality modeling. The 2016 memorandum further describes 
how these projected potential design values can be used to help 
determine which monitors should be further evaluated to potentially 
address whether emissions from other states significantly contribute to 
nonattainment or interfere with

[[Page 4027]]

maintenance of the 2012 annual PM2.5 NAAQS at those sites. 
The 2016 memorandum explains that, for purposes of addressing 
interstate transport for the 2012 PM2.5 NAAQS, it may be 
appropriate to evaluate projected air quality in 2021, which is the 
attainment deadline for 2012 PM2.5 NAAQS nonattainment areas 
classified as Moderate. Accordingly, because the available data 
includes 2017 and 2025 projected average and maximum PM2.5 
design values calculated through the CAMx photochemical model, the 2016 
memorandum suggests approaches states might use to interpolate 
PM2.5 values at sites in 2021. The 2016 memorandum indicates 
that it may be reasonable to assume receptors projected to have average 
and/or maximum design values above the NAAQS in both 2017 and 2025 are 
also likely to be either nonattainment or maintenance receptors in 
2021. Similarly, the 2016 memorandum indicates that it may be 
reasonable to assume that receptors that are projected to attain the 
NAAQS in both 2017 and 2025 are also likely to be attainment receptors 
in 2021. However, where a potential receptor is projected to be 
nonattainment or maintenance in 2017, but projected to be attainment in 
2025, the 2016 memorandum suggests that further analysis of the 
emissions and modeling may be needed to make a further judgement 
regarding the receptor status in 2021.
    The 2016 memorandum indicates that for all but one monitoring site 
in the eastern United States, with complete and valid PM2.5 
design values from 2009 to 2013, the modeling data shows that monitors 
were expected to both attain and maintain the 2012 annual 
PM2.5 NAAQS in both 2017 and 2025. The modeling results 
provided in the 2016 memorandum show that out of seven PM2.5 
monitors located in Allegheny County, Pennsylvania (PA), one monitor is 
expected to be above the 2012 annual PM2.5 NAAQS in 2017. 
Further, that monitor, the Liberty monitor (ID number 420030064), is 
projected to be above the NAAQS only under the model's maximum 
projected conditions (used in EPA's interstate transport framework to 
identify maintenance receptors) and is projected to both attain and 
maintain the NAAQS (along with all Allegheny County monitors) in 2025. 
The 2016 memorandum therefore indicates that under such a condition 
(where EPA's photochemical modeling indicates an area will maintain the 
2012 annual PM2.5 NAAQS in 2025 but not attain in 2017) 
further analysis of the site should be performed to determine if the 
site may be a nonattainment or maintenance receptor in 2021 (the 
attainment deadline for moderate PM2.5 areas).
    The 2016 memorandum also indicates that based on modeling 
projections, there are 17 potential nonattainment or maintenance 
receptors in California, located in the San Joaquin Valley and South 
Coast nonattainment areas, and one potential receptor in Shoshone 
County, Idaho.
    The 2016 memorandum also indicates that for certain states with 
incomplete ambient monitoring data, additional information including 
the latest available data should be analyzed to determine whether there 
are potential downwind air quality problems that may be impacted by 
transported emissions. These states include all or portions of Florida, 
Illinois, Idaho (outside of Shoshone County), Tennessee, and Kentucky. 
With the exception of four counties in Florida, the data quality 
problems have subsequently been resolved for these areas, and these 
areas now have current design values below the 2012 annual 
PM2.5 NAAQS and are expected to maintain the NAAQS due to 
downward emission trends for nitrogen oxides (NOX) and 
sulfur dioxide (SO2).
    IEPA's submittal indicates that the state used data from the 2016 
memorandum and supplied its own additional information in its analysis. 
EPA considered the analysis from IEPA, as well as additional analysis 
conducted by EPA, in its review of the IEPA submittal.

III. IEPA's Analysis and Conclusion

    IEPA's submittal contains a technical analysis of its interstate 
transport of pollution relative to the 2012 annual PM2.5 
NAAQS. As reflected in the EPA's 2016 memorandum, the only receptor 
identified as nonattainment or maintenance on which Illinois was deemed 
to have significant impact is the Liberty monitor (42-003-0064) in 
Allegheny County, PA located in southwest PA. In this technical 
analysis IEPA examined geographical, meteorological, and emissions 
factors to evaluate impacts on the Allegheny monitor. As stated 
previously, IEPA's technical analysis considers CSAPR rule 
implementation and EPA guidance and memoranda. IEPA did not focus on 
potential contribution to other areas EPA identified as not attaining 
the 2012 annual PM2.5 NAAQS based on monitor data in Alaska, 
California, Idaho, Nevada, or Hawaii. The distance between Illinois and 
these areas, coupled with the prevailing wind directions, leads IEPA to 
conclude that Illinois will not contribute significantly to any of the 
potential receptors in those states. Since the Allegheny County, PA, 
receptor is the only location considered downwind of Illinois, this 
submission focuses on that single receptor. IEPA concluded that 
Illinois contributes no significant impacts to the maintenance and 
attainment of NAAQS for PM2.5 in Allegheny County, PA, and 
therefore existing measures satisfy Illinois' responsibilities under 
CAA Section 110(a)(2)(D)(i)(I).
    IEPA's submission discussed geographical factors that show Illinois 
does not contribute to the nonattainment issues at the Allegheny 
monitor. As stated in IEPA's submittal, Illinois' nearest point to the 
Allegheny monitor is about 400 miles away. At this large distance, 
PM2.5 precursor emissions from Illinois are thoroughly 
dispersed in the atmosphere long before reaching PA. Furthermore, 
Illinois is required to control electric generation units (EGU) year-
round to meet annual budgets of NOX and SO2 
associated with CSAPR, so the Illinois contribution to long-range 
transport is already being minimized.
    IEPA's submission included a wind rose from the Pittsburgh/
Allegheny airport to demonstrate that the dominant wind directions in 
the monitor area are south through west, with the highest frequency 
from the south. Local emitting sources located south and west of the 
monitor were identified by IEPA in this submittal. Some sources include 
Clairton Coke Works (1.3 miles south) and U.S. Steel Corporation (2.0 
miles west). The 2011 emissions totals for all the identified sources 
were 702 tons/year (TPY) of primary PM2.5, 3,075 TPY of 
NOX, and 1,468 TPY of SO2. These large sources of 
PM2.5 and precursors of PM2.5 near the monitor 
line up with prevailing wind directions in that area, leading IEPA to 
conclude that these sources largely contribute to the nonattainment 
issues at the Allegheny monitor.
    IEPA's submission evaluated the Illinois emissions data from 
federal inventories of NOX and SO2. Emissions of 
NOX and SO2 have been steadily decreasing since 
the early 2000s due to state and federal control requirements. The 
emissions of NOX and SO2 in Illinois from all 
identified source categories have decreased by 48.5% and 64%, 
respectively, since 2002. Illinois' implementation of Tier 3 vehicle 
emission fuel standards will further reduce the on-road emissions going 
forward.
    IEPA concludes that that no further measures are necessary to 
satisfy Illinois' responsibilities under CAA Section 
110(a)(2)(D)(i)(I), because

[[Page 4028]]

Illinois does not contribute to projected nonattainment or maintenance 
issues at the Liberty monitor site. Instead, IEPA found that ambient 
air traveling from westerly and southernly winds and large sources of 
primary PM2.5, NOX, and SO2 in PA near 
the Allegheny monitor are more likely contributing to projected 
nonattainment or maintenance issues at the site.

IV. EPA's Additional Analysis, Review, and Conclusion

    The modeling information contained in EPA's 2016 memorandum shows 
that one monitor in Allegheny County, PA (the Liberty monitor, 
420030064) may have a maintenance issue in 2017, but is projected to 
both attain and maintain the NAAQS by 2025. A linear interpolation of 
the modeled design values to 2021 shows that the monitor is likely to 
both attain and maintain the standard by 2021. Emissions and air 
quality data trends help to corroborate this interpolation.
    Over the last decade, local and regional emissions reductions of 
primary PM2.5, SO2, and NOX, have led 
to large reductions in annual PM2.5 design values in 
Allegheny County, PA. In 2007, all of Allegheny County's 
PM2.5 monitors exceeded the level of the 2012 annual 
PM2.5 NAAQS (the 2005-2007 annual average design values 
ranged from 12.9-19.8 micrograms per cubic meter ([micro]g/m\3\), as 
shown in Table 1). The 2015-2017 annual average PM2.5 design 
values now show that only one monitor (Liberty, at 13.0 [micro]g/m\3\) 
exceeds the health-based annual PM2.5 NAAQS of 12.0 
[micro]g/m\3\.

                                                  Table 1--PM2.5 Annual Design Values in [micro]g/m\3\

    The Liberty monitor is already close to attaining the NAAQS and 
expected emissions reductions in the next three years will lead to 
additional reductions in measured PM2.5 concentrations. 
There are both local and regional components to the measured 
PM2.5 levels in Allegheny County and the greater Pittsburgh 
area. Previous CSAPR modeling showed that regional emissions from 
upwind states, particularly SO2 and NOX 
emissions, contribute to PM2.5 nonattainment at the Liberty 
monitor. In recent years, large SO2 and NOX 
reductions from power plants have occurred in Pennsylvania and states 
upwind from the Greater Pittsburgh region. Based on existing CSAPR 
budgets, Pennsylvania's energy sector emissions of SO2 will 
have decreased 166,000 tons between 2015-2017 as a result of CSAPR 
implementation. This is due to both the installation of emissions 
controls and retirements of electric generating units.
    Between 2011 and 2016, 27.4 gigawatts of coal-fired EGUs have 
retired in Pennsylvania and the closest upwind states (West Virginia, 
Ohio, Kentucky, Indiana, Illinois, and Michigan) according to the 
Energy Information Administration's Preliminary Monthly Electric 
Generator Inventory, April 2017 (form EIA-860M, at https://www.eia.gov/electricity/data/eia860m/xls/april_generator2017.xlsx). In addition, 
between 2017 and 2021, an additional 8.8 gigawatts of coal-fired EGUs 
are expected to retire in the same upwind states. This includes large 
EGUs such as JM Stuart in Ohio (2,308 megawatts [MW]), Killen Station 
in Ohio (600 MW), WH Sammis in Ohio (720 MW), Michigan City in Indiana 
(469 MW), Will County in Illinois (510 MW), Baldwin Energy Complex in 
Illinois (576 MW), Paradise in Kentucky (1,230 MW), and Baily in 
Indiana (480 MW). These regional coal unit retirements will lead to 
further emissions reductions which will help ensure that Alleghany 
County monitors will not have nonattainment or maintenance issues by 
2021.
    In addition to regional emissions reductions and plant closures 
noted above, additional local reductions in both direct 
PM2.5 and SO2 emissions are also expected to 
occur and should also contribute to further declines in Allegheny 
County's PM2.5 monitor concentrations. For example, 
significant SO2 reductions will occur at U.S. Steel's 
integrated steel mill facilities in southern Allegheny County due to 
reductions required via federally-enforceable permits issued by 
Allegheny County to support its attainment plan submitted to meet 
requirements in CAA Section 172(c) for the 1-hr SO2 NAAQS. 
Reductions occurred October 2018 largely due to declining sulfur 
content in the Clairton Coke Work's coke oven gas (COG) due to upgraded 
controls. Because this COG is burned at U.S. Steel's Clairton Coke 
Works, Irvin Mill, and Edgar Thompson Steel Mill, these reductions in 
sulfur content contribute to much lower PM2.5 formation from 
precursors in the immediate future after October 4, 2018 as 
SO2 is a precursor to PM2.5. Additionally, the 
expected retirement of the Bruce Mansfield Power Plant by June 2021 
should reduce precursor emissions from neighboring Beaver County, PA. 
The Allegheny County and Beaver County SO2 SIP submissions, 
which EPA is reviewing pursuant to CAA requirements, also discuss 
expected lower SO2 emissions in the Allegheny County area 
resulting from reduced sulfur content requirements in vehicle fuels, 
reductions in general emissions due to declining population in the 
Greater Pittsburgh region, and several shutdowns of significant 
emitters of SO2 in Allegheny County.
    Projected power plant closures and additional emissions controls in 
PA and upwind states will help further reduce both direct 
PM2.5 and PM2.5 precursors. Regional emission 
reductions will continue to occur from current on-the-books Federal and 
state regulations such as the Federal on-road and non-road vehicle 
programs, and various rules for major stationary emissions sources.
    EPA modeling projections, the recent downward trend in local and 
upwind emissions reductions, the expected

[[Page 4029]]

continued downward trend in emissions between 2018 and 2021, and the 
downward trend in monitored PM2.5 concentrations all 
indicate that the Liberty monitor will attain and be able to maintain 
the 2012 annual PM2.5 NAAQS by 2021.
    With respect to Florida, in the CSAPR modeling analysis for the 
1997 PM2.5 NAAQS, Florida did not have any potential 
nonattainment or maintenance receptors identified for the 1997 or 2006 
PM2.5 NAAQS. At this time, it is anticipated that this trend 
will continue; however, as there are ambient monitoring data gaps in 
the 2009-2013 data that could have been used to identify potential 
PM2.5 nonattainment and maintenance receptors for Miami/
Dade, Gilchrist, Broward and Alachua counties in Florida, the modeling 
analysis of potential receptors was not complete for these counties. 
However, the most recent ambient data (2015-2017) for these counties 
indicates design values well below the level of the 2012 annual 
PM2.5 NAAQS. In addition, the highest value for these 
observed monitors is 8.0 [micro]g/m\3\ at the Hillsborough County 
monitor (12-057-3002), which is well below the NAAQS. This is also 
consistent with historical data: Complete and valid design values in 
the 2006-2008, 2007-2009 and/or 2008-2010 periods for these counties 
were all well below the 2012 annual PM2.5 NAAQS. For these 
reasons, we find that none of the counties in Florida with monitoring 
gaps between 2009-2013 should be considered either nonattainment or 
maintenance receptors for the 2012 annual PM2.5 NAAQS. For 
these reasons, we propose to find that emissions from Illinois will not 
significantly contribute to nonattainment or interfere with maintenance 
of the 2012 annual PM2.5 NAAQS in Florida.
    The conclusions of IEPA's analysis is consistent with EPA's 
expanded review of its submittal. The area (Allegheny County, PA) to 
which Illinois' sources potentially contribute is expected to attain 
and maintain the 2012 annual PM2.5 NAAQS, and as 
demonstrated in IEPA's submittal, Illinois will not contribute to 
projected nonattainment or maintenance issues at any sites in 2021. 
IEPA's analysis shows that through permanent and enforceable measures 
currently contained in its SIP and other emissions reductions occurring 
in Illinois, monitored PM2.5 air quality in the identified 
area that Illinois sources may impact will continue to improve, and 
that no further measures are necessary to satisfy Illinois' 
responsibilities under CAA section 110(a)(2)(D)(i)(I). Therefore, EPA 
is proposing that prongs one and two of the interstate pollution 
transport element of Illinois' infrastructure SIP are approvable.

V. What action is EPA taking?

    EPA is proposing to approve a portion of IEPA's September 29, 2017 
submittal certifying that the current Illinois SIP is sufficient to 
meet the required infrastructure requirements under CAA section 
110(a)(2)(D)(i)(I), specifically prongs one and two, as set forth 
above.

VI. 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. See 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 Orders 12866 (58 
FR 51735, October 4, 1993) and 13563 (76 FR 3821, January 21, 2011);
     Is not an Executive Order 13771 (82 FR 9339, February 2, 
2017) regulatory action because SIP approvals are exempted under 
Executive Order 12866.
     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, the SIP is not approved to apply on any Indian 
reservation land or in any other area where EPA or an Indian tribe has 
demonstrated that a tribe has jurisdiction. In those areas of Indian 
country, the rule does not have tribal implications and will not impose 
substantial direct costs on tribal governments or preempt tribal law as 
specified by Executive Order 13175 (65 FR 67249, November 9, 2000).
