40 CFR Part 52
[EPA-R07-OAR-2019-0332; FRL-9995-31-Region 7]
Approval of Iowa and Nebraska Air Quality Implementation Plans;
Infrastructure SIP Requirements for the 2012 Annual Fine Particulate
Matter (PM2.5) National Ambient Air Quality Standard Interstate
Transport
AGENCY: Environmental Protection Agency (EPA).
ACTION: Proposed rule.
-----------------------------------------------------------------------
SUMMARY: The Environmental Protection Agency (EPA) is proposing to
approve elements of State Implementation Plan (SIP) submissions from
Iowa Department of Natural Resources (IDNR) and Nebraska Department of
Environmental Quality (NDEQ) for the 2012 Annual Fine Particulate
Matter (PM2.5) National Ambient Air Quality Standard
(NAAQS). The Clean Air Act (CAA) requires that each state adopt and
submit a SIP that provides for the implementation, maintenance, and
enforcement of each NAAQS promulgated by EPA, commonly referred to as
``infrastructure'' SIPs. In this action EPA is proposing to approve the
interstate transportation obligations of the State's 2012
PM2.5 NAAQS infrastructure SIP submittals.

II. What is being addressed in this document?
The EPA is proposing to approve the submittals as meeting the
submittal requirement of section 110(a)(1). The EPA is proposing to
approve certain elements of the infrastructure SIP submissions from
Iowa received on December 22, 2015, and from Nebraska received on
February 22, 2016. Specifically, the EPA is proposing to approve the
following elements of section 110(a)(2)(D)(i)(I)--significant
contribution to nonattainment (prong 1), and interfering with
maintenance of the NAAQS (prong 2). The EPA has already addressed
elements of 110(a)(2) including: (A) through (C), (D)(i)(II)--
prevention of significant deterioration of air quality (prong 3),
(D)(ii), and (E) through (H), and (J) through (M) in separate
rulemakings for Iowa and Nebraska (see docket EPA-R07-OAR-2017-0517 and
EPA-R07-OAR-2017-0477). The EPA intends to act on section
110(a)(2)(D)(i)(II)--protection of visibility (prong 4) in subsequent
rulemakings. Finally, EPA is not acting on section 110(a)(2)(I) as it
does not expect infrastructure SIP submissions to address element (I).
III. Have the requirements for approval of a SIP revision been met?
The state's submissions have met the public notice requirements for
SIP submissions in accordance with 40 CFR 51.102. The state of Iowa
held a 30-day comment period, and a public hearing on November 16,
2015. No oral or written comments were received. The state of Nebraska
held a public comment period from November 23, 2015, to December 29,
2015. The state received no comments during the public comment period.
A public hearing was held on December 29, 2015. The submissions
satisfied the completeness criteria of 40 CFR part 51, appendix V.
IV. Background
On December 14, 2012, the EPA revised the primary annual
PM2.5 NAAQS to 12.0 micrograms per cubic meter ([mu]g/m\3\).
See 78 FR 3086 (January 15, 2013). An area meets the standard if the
three-year average of its annual average PM2.5 concentration
(at each monitoring site in the area) is less than or equal to 12.0
[mu]g/m\3\. States were required to submit infrastructure SIP
submissions for the 2012 PM2.5 NAAQS to EPA no later than
December 14, 2015.
CAA section 110(a)(1) requires states to submit SIP revisions
within three years after promulgation of a new or revised NAAQS in
order to provide for the implementation, maintenance, and enforcement
of the new or revised NAAQS. CAA section 110(a)(2) outlines the
applicable requirements of such SIP submissions, which EPA has
historically referred to as ``infrastructure SIP'' submissions. Section
110(a)(2) requires states to address basic SIP elements such as
monitoring, basic program requirements (e.g., permitting), and legal
authority that are designed to assure attainment and maintenance of the
newly established or revised NAAQS. Thus, section 110(a)(1) provides
the procedural and timing requirements for infrastructure SIPs, and
section 110(a)(2) lists specific elements that states must meet for the
infrastructure SIP requirements related to a newly established or
revised NAAQS. The contents of an infrastructure SIP submission may
vary depending upon the data and analytical tools available to the
state, as well as the provisions already contained in the state's
implementation plan at the time in which the state develops and submits
the submission for a new or revised NAAQS.
Section 110(a)(2)(D) has two subsections: 110(a)(2)(D)(i) and
110(a)(2)(D)(ii). Section 110(a)(2)(D)(i) includes four distinct
components, commonly referred to as ``prongs,'' that must be addressed
in infrastructure SIP submissions. The first two prongs, which are
codified in section 110(a)(2)(D)(i)(I), require plans to prohibit any
source or other type of emissions activity in one state from
contributing significantly to nonattainment of the NAAQS in another
state (prong 1) and from interfering with maintenance of the NAAQS in
another state (prong 2). The third and fourth prongs, which are
codified in section 110(a)(2)(D)(i)(II), are provisions that prohibit
emissions activity in one state from interfering with measures required
to prevent significant deterioration of air quality in another state
(prong 3) or from interfering with measures to protect visibility in
another state (prong 4). Section 110(a)(2)(D)(ii) requires SIPs to
include provisions insuring compliance with sections 115 and 126 of the
Act, relating to interstate and international pollution abatement.\1\
---------------------------------------------------------------------------
\1\ The 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'' (2007 guidance). 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)'' (2013 guidance).
---------------------------------------------------------------------------
Through this notice, EPA is proposing to approve the prong 1 and
prong 2 portions of the infrastructure SIP submissions by Iowa and
Nebraska as demonstrating that these states do not significantly
contribute to nonattainment or interfere with maintenance of the 2012
PM2.5 NAAQS in any other state. For comprehensive
information on the 2012 PM2.5 NAAQS, please refer to the
Federal Register notice cited above.
V. Relevant Factors To Evalute the 2012 PM2.5 Intersate Transport SIPs
The EPA has developed a consistent framework for addressing
interstate transport with respect to the PM2.5 NAAQS. This
framework includes the following four steps: (1) Identify downwind
areas that are expected to have problems attaining or maintaining the
NAAQS; (2) Identify which upwind states contribute to these air quality
problems in amounts sufficient to warrant further review and analysis;
(3) Identify any emissions reductions necessary to prevent an
identified upwind state from significantly contributing to downwind
nonattainment or interfering with downwind maintenance of the NAAQS;
[[Page 30064]]
and (4) Adopt permanent and enforceable measures needed to achieve
those emissions reductions.
To help states identify the receptors expected to have problems
attaining or maintaining the 2012 annual PM2.5 NAAQS, the
EPA released a memorandum 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)'' on March 17, 2016 (herein the ``2016
Memo'').\2\ The 2016 Memo provides projected future year annual
PM2.5 design values for monitors throughout the country
based on quality assured and certified ambient monitoring data and
recent air quality modeling and explains the methodology used to
develop these projected design values. The 2016 Memo also describes how
the projected values can be used to help determine which monitors
should be further evaluated as potential receptors under step 1 of the
interstate transport framework described above, and how to determine
whether emissions from other states significantly contribute to
nonattainment or interfere with maintenance of the 2012 annual
PM2.5 NAAQS at these monitoring sites.
---------------------------------------------------------------------------
\2\ https://www.epa.gov/sites/production/files/2016-08/documents/good-neighbor-memo_implementation.pdf.
---------------------------------------------------------------------------
To develop the projected values presented in the 2016 Memo, the EPA
used the results of nationwide photochemical air quality modeling that
it recently performed to support several ozone NAAQS-related
rulemakings. Base year modeling was performed for 2011. Future year
modeling was performed for 2017 to support the Cross-State Air
Pollution Rule (CSAPR) Update for the 2008 Ozone NAAQS. See 81 FR 74504
(October 26, 2016). Future year modeling was performed for 2025 to
support the Regulatory Impact Assessment of the final 2015 Ozone
NAAQS.\3\ In addition, and relevant to this proposed action on
interstate transport SIPs for the 2012 annual PM2.5 NAAQS,
the outputs from these model runs included hourly concentrations of
PM2.5 that were used in conjunction with measured data to
project annual average PM2.5 design values for 2017 and
2025.
---------------------------------------------------------------------------
\3\ See 2015 ozone NAAQS RIA at: http://www3.epa.gov/ozonepollution/pdfs/20151001ria.pdf.
---------------------------------------------------------------------------
Areas that were designated as moderate PM2.5
nonattainment areas for the 2012 annual PM2.5 NAAQS in 2014
must attain the NAAQS by December 31, 2021, or as expeditiously as
practicable. Since modeling results are only available for 2017 and
2025, the 2016 Memo explains that one way to assess potential receptors
for 2021 \4\ is to assume that 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 EPA stated 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. Where a potential
receptor is projected to be nonattainment or maintenance in 2017, but
projected to be attainment in 2025, further analysis of the emissions
and modeling may be needed to make a further judgement regarding the
receptor status in 2021.
---------------------------------------------------------------------------
\4\ Assessing downwind PM2.5 air quality problems
based on estimates of air quality concentrations in a future year
aligned with the relevant attainment deadline is consistent with the
instructions from the United States Court of Appeals for the
District of Columbia Circuit (D.C. Circuit) in North Carolina v.
EPA, 531 F.3d 896, 911-12 (D.C. Cir. 2008), that upwind emission
reductions should be harmonized, to the extent possible, with the
attainment deadlines for downwind areas.
---------------------------------------------------------------------------
Based on this approach, the EPA identified 19 potential
nonattainment and/or maintenance receptors. All of the 17 potential
nonattainment receptors are located in California. One of the potential
maintenance-only receptors is located in Shoshone County, Idaho, and
the other potential maintenance-only receptor is located in Allegheny
County, Pennsylvania.
The 2016 memorandum also notes that because of data quality
problems, nonattainment and maintenance projections were not conducted
for monitors in all or portions of Florida, Illinois, Idaho (outside of
Shoshone County), Tennessee and Kentucky. EPA notes, however, that data
quality problems have subsequently been resolved for all of the
aforementioned areas. These areas have current design values \5\ below
the 2012 PM2.5 NAAQS and are expected to continue to
maintain the NAAQS due to downward emission trends for nitrogen oxides
(NOX) and sulfur dioxide (SO2) and therefore are
not considered potential receptors for the purpose of interstate
transport for the 2012 PM2.5 NAAQS.
---------------------------------------------------------------------------
\5\ Current design values include the 2015-2017 available and
certified data that states submitted to EPA on May 1, 2018, through
the Air Quality System.
---------------------------------------------------------------------------
After identifying potential receptors, the next step is to identify
whether upwind states contribute to air pollution at each of the
identified receptors in other states. In the 2016 Memo, the EPA did not
calculate the portion of any downwind state's predicted
PM2.5 concentrations that would result from emissions from
individual states. Accordingly, the EPA will evaluate prong 1 and 2
submissions for states using a weight of evidence analysis. This
analysis is based on a review of the state's submission and other
available information, including air quality trends; geographical and
meteorological information; local emissions in downwind states and
emissions from the upwind state; and contribution modeling from prior
interstate transport analyses. While none of these factors is by itself
fully conclusive, together they may be used in weight of evidence
analyses to determine whether the emissions from each of the states
that are the subject of this notice will significantly contribute to
nonattainment or interfere with maintenance of the 2012 annual
PM2.5 NAAQS at the identified receptors in the 2016 Memo.
VI. States' Submissions and the EPA's Analysis
Iowa: Iowa and the EPA's supplemental analysis concluded that the
state does not contribute significantly to nonattainment or interfere
with maintenance of the 2012 annual PM2.5 NAAQS in any other
state for the following reasons: (1) There are no designated
PM2.5 nonattainment areas in Iowa or in surrounding states;
(2) available monitoring data in Iowa and in the surrounding states
show annual average concentrations below the standard; and (3) Iowa has
SIP-approved regulations to assure that the state is not interfering
with attainment or maintenance of the 2012 PM2.5 NAAQS in
any other state. As noted in EPA's CSAPR analysis, Iowa's emissions
contribute to a potential maintenance receptor in Madison County,
Illinois. As stated above, the 2016 memorandum notes that because of
data quality problems, nonattainment and maintenance projections were
not conducted for monitors in a number of states including Illinois.
The EPA notes, however, that data quality problems have subsequently
been resolved for all of the aforementioned areas. These areas have
current design values below the 2012 PM2.5 NAAQS and are
expected to continue to maintain the NAAQS due to downward emission
trends for nitrogen oxides (NOX) and sulfur dioxide
(SO2) and therefore are not considered potential receptors
for the purpose of interstate transport for the 2012 PM2.5
NAAQS.
With regard to the 17 California potential receptors, located in
the San Joaquin Valley or South Coast nonattainment areas, Iowa is
nearly 1,500 miles--and downwind--from
[[Page 30065]]
California. With this large distance and a general prevailing west to
east wind flow, there is no evidence that Iowa will impact the
California potential receptors, and as a result, the EPA concludes that
emissions in Iowa do not significantly contribute to nonattainment or
interfere with maintenance.
With regard to the Shoshone County, Idaho receptor, Iowa is more
than 1000 miles and downwind of this receptor. With this distance and
prevailing wind direction, there is no evidence that Iowa will impact
this area, and as a result, EPA concludes that sources in Iowa do not
significantly contribute to nonattainment or interfere with maintenance
of the 2012 PM2.5 NAAQS at the projected Shoshone County
receptor.
The EPA's supplemental analysis focused on whether there are
maintenance or nonattainment receptors for 2021 to which Iowa is
linked. As noted above, the EPA's 2016 memorandum identifies the
Allegheny County Liberty monitor (AQS ID: 42-003-0064) as a potential
maintenance receptor in 2017, but indicates that it is likely to attain
and maintain the annual standard in 2021. The EPA's review of the CSAPR
contribution modeling indicates that Iowa's contribution to the Liberty
monitor is less than one percent of the 2012 PM2.5 NAAQS.
Based on weight of the evidence presented above, the EPA proposes
to approve Iowa's SIP submission on grounds that it addresses the
State's 110(a)(2)(D)(i)(I) good neighbor obligation for the 2012
PM2.5 standard and that the State will not significantly
contribute to nonattainment or interfere with maintenance of the 2012
PM2.5 NAAQS in any other state.
Nebraska: Nebraska and the EPA's supplemental analysis concluded
that it does not contribute significantly to nonattainment or interfere
with maintenance of the 2012 annual PM2.5 NAAQS in any other
state for the following reasons: (1) There are no designated
PM2.5 nonattainment areas in Nebraska or in surrounding
states; (2) modeling conducted by EPA in support of CSAPR indicates
that Nebraska contribution to any designated 2012 PM2.5
nonattainment area is less than one percent of the standard; and (3)
available monitoring data in Nebraska and in the surrounding states
show annual average concentrations below the standard.
With regard to the 17 California potential receptors, located in
the San Joaquin Valley or South Coast nonattainment areas, Nebraska is
well over 1,000 miles--and downwind--from California. With this large
distance and a general prevailing west to east wind flow, there is no
evidence that Nebraska will impact the California potential receptors,
and as a result, the EPA concludes that emissions in Nebraska do not
significantly contribute to nonattainment or interfere with
maintenance.
With regard to the Shoshone County, Idaho receptor, Nebraska is
more than 800 miles and downwind of this receptor. With this distance
and prevailing wind direction, there is no evidence that Nebraska will
impact this area, and as a result, the EPA concludes that sources in
Nebraska do not significantly contribute to nonattainment or interfere
with maintenance of the 2012 PM2.5 NAAQS at the projected
Shoshone County receptor.
The EPA's supplemental analysis focused on whether there are
maintenance or nonattainment receptors for 2021 to which Nebraska is
linked. As noted above, the EPA's 2016 memorandum identifies the
Allegheny County Liberty monitor (AQS ID: 42-003-0064) as a potential
maintenance receptor in 2017, but indicates that it is likely to attain
and maintain the annual standard in 2021. The EPA's review of the CSAPR
contribution modeling indicates that Nebraska's contribution to the
Liberty monitor is less than one percent of the 2012 PM2.5
NAAQS.
Based on weight of the evidence presented above, EPA proposes to
approve Nebraska's SIP submission on grounds that it addresses the
State's 110(a)(2)(D)(i)(I) good neighbor obligation for the 2012
PM2.5 standard and that the state will not significantly
contribute to nonattainment or interfere with maintenance of the 2012
PM2.5 NAAQS in any other state.
VII. What action is the EPA taking?
The EPA is proposing to approve the following elements of Iowa's
December 22, 2015, and Nebraska's February 22, 2016, infrastructure SIP
submissions: Section 110(a)(2)(D)(i)(I)--significant contribution to
nonattainment (prong 1), and interfering with maintenance of the NAAQS
(prong 2) as applicable to the 2012 Annual PM2.5 NAAQS.
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 Act and applicable
Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). Thus, in
reviewing SIP submissions, the 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 the National Technology
Transfer and Advancement Act (NTTA) because this rulemaking does not
involve technical standards; 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).
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).
