to this action because this measure does
not modify any SIP control requirement
that was in effect before November 15,
1990.
We are proposing to find that the
Valley Incentive Measure satisfies CAA
requirements for enforceability, SIP
revisions, and nontraditional emission
reduction programs as interpreted in
EPA guidance documents. The TSD
contains more information on our
evaluation of this measure.
C. Proposed Action and Request for
Public Comment
The EPA proposes to fully approve
the submitted measure under CAA
section 110(k)(3) based on a conclusion
that the measure satisfies all applicable
requirements. We will accept comments
from the public on this proposal until
April 23, 2020. If we take final action to
approve the submitted measure, our
final action will incorporate this
measure into the federally enforceable
SIP.

III. Incorporation by Reference
In this rule, the EPA is proposing to
include in a final EPA rule regulatory
text that includes incorporation by
reference. In accordance with
requirements of 1 CFR 51.5, the EPA is
proposing to incorporate by reference
the CARB measure described in Table 1
of this preamble. The EPA has made,
and will continue to make, these
materials available through
www.regulations.gov and at the EPA
Region IX Office (please contact the
person identified in the FOR FURTHER
INFORMATION CONTACT section of this
preamble for more information).
IV. Statutory and Executive Order
Reviews
Under the Clean Air Act, 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 Clean Air
Act. Accordingly, this proposed action
merely proposes to approve state law as
meeting federal requirements and does
not impose additional requirements
beyond those imposed by state law. For
that reason, this proposed 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

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 Clean Air Act;
and
• Does not provide the EPA with the
discretionary authority to address
disproportionate human health or
environmental effects with practical,
appropriate, 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 the 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).

ACTION: Proposed rule.
AGENCY:
The Environmental Protection
Agency (EPA) is proposing to approve a
revision to the Wisconsin State
Implementation Plan (SIP). On
December 13, 2019, the Wisconsin
Department of Natural Resources
(WDNR) submitted the state’s plans for
maintaining the 1997 ozone National
Ambient Air Quality Standard (NAAQS
or standard) in the following areas:
Kewaunee County, Door County,
Manitowoc County, and MilwaukeeRacine area (Kenosha, Milwaukee,
Ozaukee, Racine, Washington and
Waukesha counties). EPA is proposing
to approve these maintenance plans
because they provide for the
maintenance of the 1997 ozone NAAQS
through the end of the second 10-year
maintenance period. This action, when
finalized, would make certain
commitments related to maintenance of
the 1997 ozone NAAQS in these areas
federally enforceable as part of the
Wisconsin SIP.
DATES: Written comments must be
received at the address below on or
before April 23, 2020.

I. Summary of EPA’s Proposed Action
EPA is proposing to approve, as a
revision to the Wisconsin SIP, the 1997
ozone NAAQS maintenance plans for
the Door County, Kewaunee County,
Manitowoc County, and MilwaukeeRacine areas. The maintenance plans are
designed to keep the Kewaunee County
area in attainment of the 1997 ozone
NAAQS through 2028, the Door County
and Manitowoc County areas in
attainment through 2030, and the
Milwaukee-Racine area in attainment
through 2032.
II. Background
Ground-level ozone is formed when
oxides of nitrogen (NOX) and volatile
organic compounds (VOC) react in the
presence of sunlight. These two
pollutants are referred to as ozone
precursors. Scientific evidence indicates
that adverse public health effects occur
following exposure to ozone.
In 1979, under section 109 of the
Clean Air Act (CAA), EPA established
primary and secondary NAAQS for
ozone at 0.12 parts per million (ppm),
averaged over a 1-hour period. 44 FR
8202 (February 8, 1979). On July 18,
1997, EPA revised the primary and
secondary NAAQS for ozone to set the
acceptable level of ozone in the ambient
air at 0.08 ppm, averaged over an 8-hour
period. 62 FR 38856 (July 18, 1997).1
1 In March 2008, EPA completed another review
of the primary and secondary ozone standards and
VerDate Sep<11>2014
17:01 Mar 23, 2020
Jkt 250001
EPA set the 8-hour ozone NAAQS based
on scientific evidence demonstrating
that ozone causes adverse health effects
at lower concentrations and over longer
periods of time than was understood
when the pre-existing 1-hour ozone
NAAQS was set.
Following promulgation of a new or
revised NAAQS, EPA is required by the
CAA to designate areas throughout the
nation as attaining or not attaining the
NAAQS. On April 30, 2004 (69 FR
23857), EPA designated Kewaunee
County, Door County, Manitowoc
County, and the Milwaukee-Racine area
as nonattainment for the 1997 ozone
NAAQS, and the designations became
effective on June 15, 2004. Under the
CAA, states are also required to adopt
and submit SIPs to implement,
maintain, and enforce the NAAQS in
designated nonattainment areas and
throughout the state.
When a nonattainment area has three
years of complete, certified air quality
data that has been determined to attain
the 1997 ozone NAAQS, and the area
has met other required criteria described
in section 107(d)(3)(E) of the CAA, the
state can submit to EPA a request to be
redesignated to attainment, referred to
as a ‘‘maintenance area’’.2 One of the
criteria for redesignation is to have an
approved maintenance plan under CAA
section 175A. The maintenance plan
must demonstrate that the area will
continue to maintain the standard for
the period extending 10 years after
redesignation, and it must contain such
additional measures as necessary to
ensure maintenance and such
contingency provisions as necessary to
assure that violations of the standard
will be promptly corrected. At the end
of the eighth year after the effective date
of the redesignation, the state must also
submit a second maintenance plan to
ensure ongoing maintenance of the
standard for an additional 10 years.
CAA section 175A.
EPA has published long-standing
guidance for states on developing
tightened them further by lowering the level for
both to 0.075 ppm. 73 FR 16436 (March 27, 2008).
Additionally, in October 2015, EPA completed a
review of the primary and secondary ozone
standards and tightened them by lowering the level
for both to 0.70 ppm. 80 FR 65292 (October 26,
2015).
2 Section 107(d)(3)(E) of the CAA sets out the
requirements for redesignation. They include
attainment of the NAAQS, full approval under
section 110(k) of the applicable SIP, determination
that improvement in air quality is a result of
permanent and enforceable reductions in emissions,
demonstration that the state has met all applicable
section 110 and part D requirements, and a fully
approved maintenance plan under CAA section
175A.

maintenance plans.3 The Calcagni
Memorandum provides that states may
generally demonstrate maintenance by
either performing air quality modeling
to show that the future mix of sources
and emission rates will not cause a
violation of the NAAQS or by showing
that future emissions of a pollutant and
its precursors will not exceed the level
of emissions during a year when the
area was attaining the NAAQS (i.e.,
attainment year inventory). See Calcagni
Memorandum at 9.
On June 12, 2007, WDNR submitted a
request to EPA to redesignate Kewaunee
County to attainment for the 1997 ozone
NAAQS. This submittal included a plan
to maintain the 1997 ozone NAAQS in
Kewaunee County through 2018 as a
revision to the Wisconsin SIP. EPA
approved the Kewaunee County
maintenance plan and the state’s request
to redesignate the area to attainment for
the 1997 ozone NAAQS on May 21,
2008 (73 FR 29436).
On September 11, 2009, WDNR
submitted a request to redesignate Door
County and Manitowoc County to
attainment for the 1997 ozone NAAQS.
This submittal included a plan to
maintain the 1997 ozone NAAQS in
Door County and Manitowoc County
through 2020 as a revision to the
Wisconsin SIP. EPA approved the Door
County and Manitowoc County
maintenance plans and the state’s
request to redesignate the areas to
attainment for the 1997 ozone NAAQS
on July 12, 2010 (75 FR 39635).
On September 11, 2009, WDNR
submitted a request to redesignate the
Milwaukee-Racine area to attainment for
the 1997 ozone NAAQS.4 This submittal
included a plan to maintain the 1997
ozone NAAQS in the Milwaukee-Racine
area through 2022 as a revision to the
Wisconsin SIP. EPA approved the
Milwaukee-Racine area maintenance
plan and the state’s request to
redesignate the area to attainment for
the 1997 ozone NAAQS on July 31, 2012
(77 FR 45252).
Under CAA section 175A(b), states
must submit a revision to the first
maintenance plan eight years after
redesignation to provide for
maintenance of the NAAQS for ten
additional years following the end of the
first 10-year period. EPA’s final
implementation rule for the 2008 ozone
NAAQS revoked the 1997 ozone
NAAQS and stated that one

Redesignate Areas to Attainment,’’ Memorandum
from John Calcagni, Director, Air Quality
Management Division, September 4, 1992 (the
‘‘Calcagni Memorandum’’).
4 WDNR supplemented the submittal on
November 16, 2011.
E:\FR\FM\24MRP1.SGM
24MRP1
16592
Federal Register / Vol. 85, No. 57 / Tuesday, March 24, 2020 / Proposed Rules
consequence of revocation was that
areas that had been redesignated to
attainment (i.e., maintenance areas) for
the 1997 standard no longer needed to
submit second 10-year maintenance
plans under CAA section 175A(b).5 In
South Coast Air Quality Management
District v. EPA (South Coast II), the D.C.
Circuit vacated EPA’s interpretation
that, because of the revocation of the
1997 ozone standard, second
maintenance plans were not required for
‘‘orphan maintenance areas,’’ i.e., areas
designated attainment for the 2008
NAAQS but nonattainment for the 1997
NAAQS. South Coast, 882 F.3d 1138
(D.C. Cir. 2018). Thus, states with these
‘‘orphan maintenance areas’’ under the
1997 ozone NAAQS must submit
maintenance plans for the second
maintenance period. Accordingly, on
December 13, 2019, WDNR submitted a
second maintenance plan which shows
attainment of the 1997 ozone NAAQS
for: Kewaunee County through 2028;
Door County and Manitowoc County
through 2030; and the MilwaukeeRacine area through 2032, i.e., through
the end of the full 20-year maintenance
period for each of the areas.
III. EPA’s Evaluation of WDNR’s SIP
Submittal
A. Second Maintenance Plan
Section 175A of the CAA sets forth
the elements of a maintenance plan for
areas seeking redesignation from
nonattainment to attainment. Under
section 175A, the maintenance plan
must demonstrate continued attainment
of the NAAQS for at least 10 years after
the Administrator approves a
redesignation to attainment. Eight years
after the redesignation, the state must
submit a revised maintenance plan
which demonstrates that attainment of
the NAAQS will continue for an
additional 10 years beyond the initial
10-year maintenance 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 the future NAAQS
violation.
The Calcagni Memorandum provides
further guidance on the content of a
maintenance plan, explaining that a
maintenance plan should address five
elements: (1) An attainment emission
inventory; (2) a maintenance
demonstration; (3) a commitment for
continued air quality monitoring; (4) a
process for verification of continued
attainment; and (5) a contingency plan.
On December 13, 2019, WDNR
submitted, as a SIP revision, plans to
provide for maintenance of the 1997
ozone standard in: The Kewaunee
County area through 2028, the Door
County and Manitowoc County areas
through 2030, and the MilwaukeeRacine area through 2032, each
respectively more than 20 years after the
effective date of the redesignation to
attainment. As discussed below, EPA
proposes to find that WDNR’s second
maintenance plans include the
necessary components and to approve
the maintenance plans as revisions to
the Wisconsin SIP.
1. Attainment Inventory
a. Kewaunee County
The CAA section 175A maintenance
plan approved by EPA for the first 10year period included an attainment
inventory for the Kewaunee County area
that reflects typical summer day VOC
and NOX emissions in 2005. This
inventory is summarized in Table 1
below.

attainment of the 1997 ozone NAAQS in
2014, this is also an appropriate year to
use for an attainment year inventory.
WDNR is using 2014 summer day
emissions from the EPA 2014 version
7.0 modeling platform as the basis for
the attainment inventory presented in
Tables 7 and 8 below.8 These data are
based on the most recently available
National Emissions Inventory (2014 NEI
version 2).

2. Maintenance Demonstration
a. Kewaunee County
WDNR is demonstrating maintenance
through 2028 for the Kewaunee County
area by showing that future emissions of
VOC and NOX remain at or below
attainment year emission levels. 2028 is
an appropriate maintenance year for
Kewaunee County because it is more
than 10 years beyond the first 10-year
maintenance period. The 2028
emissions inventory is projected from
the EPA 2011 version 6.3 modeling
platform.9 The relevant inventory
scenario names are ‘‘2014fd’’ and
‘‘2028el.’’ The 2028 scenario was used
in past air quality modeling for the
regional haze program. The 2028
summer day emissions inventory for
Kewaunee County is summarized in
Table 9 below. Table 10 documents
changes in NOX and VOC emissions in
Kewaunee County between 2005, 2014
and 2028.

In summary, the maintenance
demonstration for the Kewaunee County
area shows maintenance of the 1997
ozone standard by providing emissions
information to support the
demonstration that future emissions of
NOX and VOC will remain at or below
2014 emission levels when taking into
account both future source growth and
implementation of future controls. Table
10 shows that VOC and NOX emissions
in Kewaunee County are projected to
decrease by 0.76 tpd and 1.72 tpd,
respectively, between 2014 and 2028.
b. Door and Manitowoc
WDNR is demonstrating maintenance
through 2030 for the Door County and
Manitowoc County areas by showing
that future emissions of VOC and NOX
remain at or below attainment year
emission levels. 2030 is an appropriate
maintenance year for the Door County
and Manitowoc County areas because it
is more than 10 years beyond the first
10-year maintenance period. The 2030
emissions inventory is projected from
the EPA 2011 version 6.3 modeling
platform.10 The relevant inventory
scenario names are ‘‘2014fd’’ and
‘‘2028el.’’ The 2028 scenario was used
in past air quality modeling for the
regional haze program. WDNR projected
emissions from 2028 to 2030 for the
Door County and Manitowoc County
areas based on EPA’s 2028 emission
inventory projections from EPA’s 6.3
modeling platform. WDNR projected
that emissions for 2030 would remain at
2028 levels for the Door County and
Manitowoc County areas. WDNR’s
approach is conservative as emissions
are expected to further decrease from
2028 to 2030 due to decreases in mobile
source emissions through continued
implementation of vehicle emissions
standard and vehicle fleet turn over.
The 2030 summer day emissions
inventory for the Door County and
Manitowoc County areas are
summarized in Table 11 below. Tables
12 and 13 document changes in NOX
and VOC emissions in Door County and
Manitowoc County between 2007, 2014

In summary, the maintenance
demonstration for the Door County and
Manitowoc County areas shows
maintenance of the 1997 ozone standard
by providing emissions information to
support the demonstration that future
emissions of NOX and VOC will remain
at or below 2014 emission levels when
taking into account both future source
growth and implementation of future
controls. Table 12 shows VOC and NOX
emissions in Door County are projected
to decrease by 3.62 tpd and 4.14 tpd,
respectively, between 2014 and 2030.
Table 13 shows VOC and NOX
emissions in Manitowoc County are
projected to decrease by 1.16 tpd and
4.44 tpd, respectively, between 2014
and 2030.
c. Milwaukee-Racine Area
WDNR is demonstrating maintenance
through 2032 for the Milwaukee-Racine
area by showing that future emissions of
VOC and NOX remain at or below
attainment year emission levels. 2032 is
an appropriate maintenance year for the
Milwaukee-Racine area because it is
more than 10 years beyond the first 10year maintenance period. The 2028
emissions inventory is projected from
the EPA 2011 version 6.3 modeling
platform.11 The relevant inventory
scenario names are ‘‘2014fd’’ and
‘‘2028el.’’ The 2028 scenario was used
in past air quality modeling for the
regional haze program. WDNR projected
emissions from 2028 to 2032 for
Milwaukee-Racine area based on EPA’s
2028 emission inventory projections
from EPA’s 6.3 modeling platform.
WDNR projected that emissions for 2032
would remain at 2028 levels for
Milwaukee-Racine area. WDNR’s
approach is conservative as emissions
are expected to further decrease from
2028 to 2032 due to decreases in mobile
source emissions through continued
implementation of vehicle emissions
standard and vehicle fleet turn over.
The 2032 summer day emissions
inventory for the Milwaukee-Racine
area is summarized in Tables 14 and 15

In summary, the maintenance
demonstration for the MilwaukeeRacine area shows maintenance of the
1997 ozone standard by providing
emissions information to support the
demonstration that future emissions of
NOX and VOC will remain at or below
2014 emission levels when taking into
account both future source growth and
implementation of future controls. Table
16 shows that VOC and NOX emissions
in Milwaukee-Racine area are projected
to decrease by 26.27 tpd and 63.68 tpd,
respectively, between 2014 and 2032.
3. Continued Air Quality Monitoring
WDNR commits to continue to
operate an approved ozone monitoring
network in Kewaunee County, Door
County, Manitowoc County and the
Milwaukee-Racine area. WDNR commits
to consult with EPA prior to making
changes to the existing monitoring
network should changes become
necessary in the future. WDNR remains
obligated to meet monitoring
requirements and continue to quality
assure monitoring data in accordance
with 40 CFR part 58, and to enter all
data into the Air Quality System (AQS)
in accordance with Federal guidelines.

4. Verification of Continued Attainment
WDNR has the legal authority to
enforce and implement the
requirements of the maintenance plans
for Kewaunee County, Door County,
Manitowoc County and the MilwaukeeRacine area. This includes the authority
VerDate Sep<11>2014
17:01 Mar 23, 2020
Jkt 250001
to adopt, implement, and enforce any
subsequent emission control measures
determined to be necessary to correct
future ozone attainment problems.
Verification of continued attainment
is accomplished through operation of
the ambient ozone monitoring network
and the periodic update of the area’s
emissions inventory. WDNR will
continue to operate an approved ozone
monitoring network in Kewaunee
County, Door County, Manitowoc
County and the Milwaukee-Racine area.
There are no plans to discontinue
operation, relocate, or otherwise change
the existing ozone monitoring network
other than through revisions to the
Wisconsin Monitoring Network Plan
approved by EPA.
In addition, to track future levels of
emissions, WDNR will continue to
develop and submit to EPA updated
emission inventories for all source
categories at least once every three
years, consistent with the requirements
of 40 CFR part 51, subpart A, and in 40
CFR 51.122. The Consolidated
Emissions Reporting Rule (CERR) was
promulgated by EPA on June 10, 2002
(67 FR 39602). The CERR was replaced
by the Annual Emissions Reporting
Requirements (AERR) on December 17,
2008 (73 FR 76539).
5. Contingency Plan
Section 175A of the CAA requires that
the state must adopt a maintenance
plan, as a SIP revision, that includes
such contingency measures as EPA
PO 00000
Frm 00026
Fmt 4702
Sfmt 4702
deems necessary to assure that the state
will promptly correct a violation of the
NAAQS that occurs after redesignation
of the area to attainment of the NAAQS.
The maintenance plan must identify:
The contingency measures to be
considered and, if needed for
maintenance, adopted and
implemented; a schedule and procedure
for adoption and implementation; and,
a time limit for action by the state. The
state should also identify specific
indicators to be used to determine when
the contingency measures need to be
considered, adopted, and implemented.
The maintenance plan must include a
commitment that the state will
implement all measures with respect to
the control of the pollutant that were
contained in the SIP before
redesignation of the area to attainment
in accordance with section 175A(d) of
the CAA.
As required by section 175A of the
CAA, WDNR has adopted contingency
plans for Kewaunee County, Door
County, Manitowoc County and the
Milwaukee-Racine area to address
possible future ozone air quality
problems. The contingency plans
adopted by WDNR have two levels of
response: A warning level response and
an action level response.
In WDNR’s plans, a warning level
response will be triggered when an
annual fourth high monitored value
higher than the NAAQS is monitored
within the maintenance area. A warning
level response will consist of WDNR

lotter on DSKBCFDHB2PROD with PROPOSALS
16598
Federal Register / Vol. 85, No. 57 / Tuesday, March 24, 2020 / Proposed Rules
conducting a study to determine
whether the ozone value indicates a
trend toward higher ozone values and
whether emissions are significantly
higher than projected in the
maintenance plan. The study will
evaluate whether the actual emissions
have deviated significantly from the
emissions projections contained in the
maintenance plan for the nonattainment
areas, along with an evaluation of which
sectors and states are responsible for
any emissions increases. The study will
also assess whether unusual
meteorological conditions during the
high-ozone year led to the high
monitored ozone concentrations. The
study will evaluate whether the trend, if
any, is likely to continue and, if so, the
control measures necessary to reverse
the trend. The study will consider ease
and timing of implementation as well as
economic and social impacts. The study
findings will be completed no later than
the beginning of the following summer
ozone control period (May 1).
Implementation of necessary controls in
response to a warning level response
trigger will follow the procedures for
control selection and implementation
outlined under the action level
response.
In WDNR’s plans, an action level
response is triggered when a three-year
design value exceeding the level of the
1997 ozone NAAQS is monitored within
the maintenance area. In the event that
the action level is triggered and is not
found to be due to an exceptional event,
malfunction, or noncompliance with a
permit condition or rule requirement,
WDNR, in conjunction with the
metropolitan planning organization or
regional council of governments, will
determine what additional control
measures are needed to ensure future
attainment of the ozone standard.
Control measures selected will be
adopted and implemented within 18
months of the certification of the
monitoring data that triggered the action
level response. WDNR may also
consider if significant new regulations
not currently included as part of the
maintenance provisions will be
implemented in a timely manner and
would thus constitute an adequate
contingency measure response.
WDNR included the following list of
potential contingency measures in its
maintenance plans:
1. Implementation of any federally
promulgated rule regulating transport of
ozone precursors;
2. Updated Federal NOX emission
limits for heavy-duty vehicles;
3. Updated (Phase 2) Federal fuel
efficiency standards for medium and
heavy-duty engines and vehicles;

Jkt 250001
4. New Federal regulations on the sale
of aftermarket catalysts for vehicle
catalytic converters;
5. Anti-idling control program for
mobile sources, targeting diesel
vehicles;
6. Diesel exhaust retrofits;
7. Traffic flow improvements;
8. Park and ride facilities;
9. Rideshare/carpool program;
10. Expansion of the vehicle
emissions testing program.
EPA has concluded that the
maintenance plans adequately addresses
the five basic components of a
maintenance plan required under
Section 175A of the CAA: Attainment
inventory, maintenance demonstration,
monitoring network, verification of
continued attainment, and a
contingency plan. Thus, EPA proposes
to find that the maintenance plans SIP
revision submitted by WDNR for
Kewaunee County, Door County,
Manitowoc County and the MilwaukeeRacine area meet the requirements of
section 175A of the CAA.
B. Transportation Conformity
Transportation conformity is required
by section 176(c) of the CAA.
Conformity to a SIP means that
transportation activities will not
produce new air quality violations,
worsen existing violations, or delay
timely attainment of the NAAQS (CAA
176(c)(1)(B)). EPA’s conformity rule at
40 CFR part 93 requires that
transportation plans, programs and
projects conform to SIPs and establish
the criteria and procedures for
determining whether they conform. The
conformity rule generally requires a
demonstration that emissions from the
Regional Transportation Plan and the
Transportation Improvement Program
(TIP) are consistent with the motor
vehicle emissions budget (MVEB)
contained in the control strategy SIP
revision or maintenance plan (40 CFR
93.101, 93.118, and 93.124). A MVEB is
defined as ‘‘that portion of the total
allowable emissions defined in the
submitted or approved control strategy
implementation plan revision or
maintenance plan for a certain date for
the purpose of meeting reasonable
further progress milestones or
demonstrating attainment or
maintenance of the NAAQS, for any
criteria pollutant or its precursors,
allocated to highway and transit vehicle
use and emissions (40 CFR 93.101).’’
EPA’s current transportation
conformity regulation requires a
regional emissions analysis only during
the time period beginning one year after
a nonattainment designation for a
particular NAAQS until the effective
PO 00000
Frm 00027
Fmt 4702
Sfmt 4702
date of revocation of that NAAQS (40
CFR 93.109(c)). Therefore, pursuant to
the conformity regulation, a regional
emissions analysis using MVEBs is not
required for conformity determinations
for the 1997 ozone NAAQS because that
NAAQS has been revoked (80 FR
12264). As no regional emissions
analysis is required for Kewaunee
County, Door County, Manitowoc
County or the Milwaukee-Racine area,
transportation conformity for the 1997
ozone NAAQS can be demonstrated by
a Metropolitan Planning Organization
and Department of Transportation for
transportation plans and TIPs by
showing that the remaining criteria
contained in Table 1 in 40 CFR 93.109,
and 40 CFR 93.108 have been met.
IV. Proposed Action
Under sections 110(k) and 175A of the
CAA and for the reasons set forth above,
EPA is proposing to approve the
Kewaunee County, Door County and
Manitowoc County, and the MilwaukeeRacine area second maintenance plans
for the 1997 Ozone NAAQS, submitted
by WDNR on December 13, 2019, as a
revision to the Wisconsin SIP. These
second maintenance plans are designed
to keep the Kewaunee County area in
attainment of the 1997 ozone NAAQS
through 2028, Door County and
Manitowoc County in attainment of the
1997 ozone NAAQS though 2030, and
the Milwaukee-Racine area in
attainment of the 1997 ozone NAAQS
through 2032.
V. 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 proposed
action merely proposes to approve state
law as meeting Federal requirements
and does not impose additional
requirements beyond those imposed by
state law. For that reason, this proposed
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
E:\FR\FM\24MRP1.SGM
24MRP1
Federal Register / Vol. 85, No. 57 / Tuesday, March 24, 2020 / Proposed Rules
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
disproportionate human health or
environmental effects with practical,
appropriate, 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).

I. Background for Proposed Action
On January 27, 2014, Ecology
submitted revisions to update the
general air quality regulations contained
in Chapter 173–400 Washington
Administrative Code (WAC), which the
EPA approved in three phases on
October 3, 2014 (79 FR 59653),
November 7, 2014 (79 FR 66291), and
April 29, 2015 (80 FR 23721).1 Under
the revised applicability provisions of
WAC 173–400–020 approved into the
SIP on October 3, 2014, the regulations
contained in Chapter 173–400 WAC
apply statewide, ‘‘. . . except for
specific subsections where a local
authority has adopted and implemented
corresponding local rules that apply
only to sources subject to local
jurisdiction as provided under Revised
Code of Washington (RCW) 70.94.141
and 70.94.331.’’ 2 Therefore, the EPA’s
approval of Ecology’s January 2014
submittal applied only to geographic
areas and source categories under
Ecology’s direct jurisdiction. We stated
that we would address the revised
Chapter 173–400 WAC regulations as
they apply to local clean air agency
jurisdictions on a case-by-case basis in
separate, future actions.
On February 6, 2020, the Director of
Ecology, as the Governor’s designee for
SIP revisions, submitted a request to
update the air quality regulations in the
SIP as they apply to NWCAA’s
jurisdiction in 40 CFR part 52.2470(c),
1 In subsequent actions on September 29, 2016
(81 FR 66823) and October 6, 2016 (81 FR 69385)
we made minor corrections to our previous
approval of Chapter 173–400 WAC and approved
revised WAC provisions that incorporated by
reference the most recent changes to the Federal
regulations. Additionally, on December 4, 2019 (84
FR 66363) we proposed to approve additional
changes to Chapter 173–400 WAC state effective
September 16, 2018 and November 25, 2018, which
we are in the processes of finalizing.

AGENCY: Environmental Protection Agency (EPA).
ACTION: Proposed rule.
-----------------------------------------------------------------------
SUMMARY: The Environmental Protection Agency (EPA) is proposing to
approve a revision to the Wisconsin State Implementation Plan (SIP). On
December 13, 2019, the Wisconsin Department of Natural Resources (WDNR)
submitted the state's plans for maintaining the 1997 ozone National
Ambient Air Quality Standard (NAAQS or standard) in the following
areas: Kewaunee County, Door County, Manitowoc County, and Milwaukee-
Racine area (Kenosha, Milwaukee, Ozaukee, Racine, Washington and
Waukesha counties). EPA is proposing to approve these maintenance plans
because they provide for the maintenance of the 1997 ozone NAAQS
through the end of the second 10-year maintenance period. This action,
when finalized, would make certain commitments related to maintenance
of the 1997 ozone NAAQS in these areas federally enforceable as part of
the Wisconsin SIP.
DATES: Written comments must be received at the address below on or
before April 23, 2020.

I. Summary of EPA's Proposed Action
EPA is proposing to approve, as a revision to the Wisconsin SIP,
the 1997 ozone NAAQS maintenance plans for the Door County, Kewaunee
County, Manitowoc County, and Milwaukee-Racine areas. The maintenance
plans are designed to keep the Kewaunee County area in attainment of
the 1997 ozone NAAQS through 2028, the Door County and Manitowoc County
areas in attainment through 2030, and the Milwaukee-Racine area in
attainment through 2032.
II. Background
Ground-level ozone is formed when oxides of nitrogen
(NOX) and volatile organic compounds (VOC) react in the
presence of sunlight. These two pollutants are referred to as ozone
precursors. Scientific evidence indicates that adverse public health
effects occur following exposure to ozone.
In 1979, under section 109 of the Clean Air Act (CAA), EPA
established primary and secondary NAAQS for ozone at 0.12 parts per
million (ppm), averaged over a 1-hour period. 44 FR 8202 (February 8,
1979). On July 18, 1997, EPA revised the primary and secondary NAAQS
for ozone to set the acceptable level of ozone in the ambient air at
0.08 ppm, averaged over an 8-hour period. 62 FR 38856 (July 18,
1997).\1\ EPA set the 8-hour ozone NAAQS based on scientific evidence
demonstrating that ozone causes adverse health effects at lower
concentrations and over longer periods of time than was understood when
the pre-existing 1-hour ozone NAAQS was set.
---------------------------------------------------------------------------
\1\ In March 2008, EPA completed another review of the primary
and secondary ozone standards and tightened them further by lowering
the level for both to 0.075 ppm. 73 FR 16436 (March 27, 2008).
Additionally, in October 2015, EPA completed a review of the primary
and secondary ozone standards and tightened them by lowering the
level for both to 0.70 ppm. 80 FR 65292 (October 26, 2015).
---------------------------------------------------------------------------
Following promulgation of a new or revised NAAQS, EPA is required
by the CAA to designate areas throughout the nation as attaining or not
attaining the NAAQS. On April 30, 2004 (69 FR 23857), EPA designated
Kewaunee County, Door County, Manitowoc County, and the Milwaukee-
Racine area as nonattainment for the 1997 ozone NAAQS, and the
designations became effective on June 15, 2004. Under the CAA, states
are also required to adopt and submit SIPs to implement, maintain, and
enforce the NAAQS in designated nonattainment areas and throughout the
state.
When a nonattainment area has three years of complete, certified
air quality data that has been determined to attain the 1997 ozone
NAAQS, and the area has met other required criteria described in
section 107(d)(3)(E) of the CAA, the state can submit to EPA a request
to be redesignated to attainment, referred to as a ``maintenance
area''.\2\ One of the criteria for redesignation is to have an approved
maintenance plan under CAA section 175A. The maintenance plan must
demonstrate that the area will continue to maintain the standard for
the period extending 10 years after redesignation, and it must contain
such additional measures as necessary to ensure maintenance and such
contingency provisions as necessary to assure that violations of the
standard will be promptly corrected. At the end of the eighth year
after the effective date of the redesignation, the state must also
submit a second maintenance plan to ensure ongoing maintenance of the
standard for an additional 10 years. CAA section 175A.
---------------------------------------------------------------------------
\2\ Section 107(d)(3)(E) of the CAA sets out the requirements
for redesignation. They include attainment of the NAAQS, full
approval under section 110(k) of the applicable SIP, determination
that improvement in air quality is a result of permanent and
enforceable reductions in emissions, demonstration that the state
has met all applicable section 110 and part D requirements, and a
fully approved maintenance plan under CAA section 175A.
---------------------------------------------------------------------------
EPA has published long-standing guidance for states on developing
maintenance plans.\3\ The Calcagni Memorandum provides that states may
generally demonstrate maintenance by either performing air quality
modeling to show that the future mix of sources and emission rates will
not cause a violation of the NAAQS or by showing that future emissions
of a pollutant and its precursors will not exceed the level of
emissions during a year when the area was attaining the NAAQS (i.e.,
attainment year inventory). See Calcagni Memorandum at 9.
---------------------------------------------------------------------------
\3\ ``Procedures for Processing Requests to Redesignate Areas to
Attainment,'' Memorandum from John Calcagni, Director, Air Quality
Management Division, September 4, 1992 (the ``Calcagni
Memorandum'').
---------------------------------------------------------------------------
On June 12, 2007, WDNR submitted a request to EPA to redesignate
Kewaunee County to attainment for the 1997 ozone NAAQS. This submittal
included a plan to maintain the 1997 ozone NAAQS in Kewaunee County
through 2018 as a revision to the Wisconsin SIP. EPA approved the
Kewaunee County maintenance plan and the state's request to redesignate
the area to attainment for the 1997 ozone NAAQS on May 21, 2008 (73 FR
29436).
On September 11, 2009, WDNR submitted a request to redesignate Door
County and Manitowoc County to attainment for the 1997 ozone NAAQS.
This submittal included a plan to maintain the 1997 ozone NAAQS in Door
County and Manitowoc County through 2020 as a revision to the Wisconsin
SIP. EPA approved the Door County and Manitowoc County maintenance
plans and the state's request to redesignate the areas to attainment
for the 1997 ozone NAAQS on July 12, 2010 (75 FR 39635).
On September 11, 2009, WDNR submitted a request to redesignate the
Milwaukee-Racine area to attainment for the 1997 ozone NAAQS.\4\ This
submittal included a plan to maintain the 1997 ozone NAAQS in the
Milwaukee-Racine area through 2022 as a revision to the Wisconsin SIP.
EPA approved the Milwaukee-Racine area maintenance plan and the state's
request to redesignate the area to attainment for the 1997 ozone NAAQS
on July 31, 2012 (77 FR 45252).
---------------------------------------------------------------------------
\4\ WDNR supplemented the submittal on November 16, 2011.
---------------------------------------------------------------------------
Under CAA section 175A(b), states must submit a revision to the
first maintenance plan eight years after redesignation to provide for
maintenance of the NAAQS for ten additional years following the end of
the first 10-year period. EPA's final implementation rule for the 2008
ozone NAAQS revoked the 1997 ozone NAAQS and stated that one
[[Page 16592]]
consequence of revocation was that areas that had been redesignated to
attainment (i.e., maintenance areas) for the 1997 standard no longer
needed to submit second 10-year maintenance plans under CAA section
175A(b).\5\ In South Coast Air Quality Management District v. EPA
(South Coast II), the D.C. Circuit vacated EPA's interpretation that,
because of the revocation of the 1997 ozone standard, second
maintenance plans were not required for ``orphan maintenance areas,''
i.e., areas designated attainment for the 2008 NAAQS but nonattainment
for the 1997 NAAQS. South Coast, 882 F.3d 1138 (D.C. Cir. 2018). Thus,
states with these ``orphan maintenance areas'' under the 1997 ozone
NAAQS must submit maintenance plans for the second maintenance period.
Accordingly, on December 13, 2019, WDNR submitted a second maintenance
plan which shows attainment of the 1997 ozone NAAQS for: Kewaunee
County through 2028; Door County and Manitowoc County through 2030; and
the Milwaukee-Racine area through 2032, i.e., through the end of the
full 20-year maintenance period for each of the areas.
---------------------------------------------------------------------------
\5\ See 80 FR 12315 (March 6, 2015).
---------------------------------------------------------------------------
III. EPA's Evaluation of WDNR's SIP Submittal
A. Second Maintenance Plan
Section 175A of the CAA sets forth the elements of a maintenance
plan for areas seeking redesignation from nonattainment to attainment.
Under section 175A, the maintenance plan must demonstrate continued
attainment of the NAAQS for at least 10 years after the Administrator
approves a redesignation to attainment. Eight years after the
redesignation, the state must submit a revised maintenance plan which
demonstrates that attainment of the NAAQS will continue for an
additional 10 years beyond the initial 10-year maintenance 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 the future NAAQS violation.
The Calcagni Memorandum provides further guidance on the content of
a maintenance plan, explaining that a maintenance plan should address
five elements: (1) An attainment emission inventory; (2) a maintenance
demonstration; (3) a commitment for continued air quality monitoring;
(4) a process for verification of continued attainment; and (5) a
contingency plan.
On December 13, 2019, WDNR submitted, as a SIP revision, plans to
provide for maintenance of the 1997 ozone standard in: The Kewaunee
County area through 2028, the Door County and Manitowoc County areas
through 2030, and the Milwaukee-Racine area through 2032, each
respectively more than 20 years after the effective date of the
redesignation to attainment. As discussed below, EPA proposes to find
that WDNR's second maintenance plans include the necessary components
and to approve the maintenance plans as revisions to the Wisconsin SIP.
1. Attainment Inventory
a. Kewaunee County
The CAA section 175A maintenance plan approved by EPA for the first
10-year period included an attainment inventory for the Kewaunee County
area that reflects typical summer day VOC and NOX emissions
in 2005. This inventory is summarized in Table 1 below.

------------------------------------------------------------------------
In addition, because the Kewaunee County area continued to monitor
attainment of the 1997 ozone NAAQS in 2014, this is also an appropriate
year to use for an attainment year inventory. WDNR is using 2014 summer
day emissions from the EPA 2014 version 7.0 modeling platform as the
basis for the attainment inventory presented in Table 2 below.\6\ These
data are based on the most recently available National Emissions
Inventory (2014 NEI version 2).

b. Door County and Manitowoc County
The CAA section 175A maintenance plan approved by EPA for the first
10-year period included an attainment inventory for the Door County and
Manitowoc County areas that reflects typical summer day VOC and

continued to monitor attainment of the 1997 ozone NAAQS in 2014, this
is also an appropriate year to use for an attainment year inventory.
WDNR is using 2014 summer day emissions from the EPA 2014 version 7.0
modeling platform as the basis for the attainment inventory presented

2. Maintenance Demonstration
a. Kewaunee County
WDNR is demonstrating maintenance through 2028 for the Kewaunee
County area by showing that future emissions of VOC and NOX
remain at or below attainment year emission levels. 2028 is an
appropriate maintenance year for Kewaunee County because it is more
than 10 years beyond the first 10-year maintenance period. The 2028
emissions inventory is projected from the EPA 2011 version 6.3 modeling
platform.\9\ The relevant inventory scenario names are ``2014fd'' and
``2028el.'' The 2028 scenario was used in past air quality modeling for
the regional haze program. The 2028 summer day emissions inventory for
Kewaunee County is summarized in Table 9 below. Table 10 documents
changes in NOX and VOC emissions in Kewaunee County between
2005, 2014 and 2028.

In summary, the maintenance demonstration for the Kewaunee County
area shows maintenance of the 1997 ozone standard by providing
emissions information to support the demonstration that future
emissions of NOX and VOC will remain at or below 2014
emission levels when taking into account both future source growth and
implementation of future controls. Table 10 shows that VOC and
NOX emissions in Kewaunee County are projected to decrease
by 0.76 tpd and 1.72 tpd, respectively, between 2014 and 2028.
b. Door and Manitowoc
WDNR is demonstrating maintenance through 2030 for the Door County
and Manitowoc County areas by showing that future emissions of VOC and
NOX remain at or below attainment year emission levels. 2030
is an appropriate maintenance year for the Door County and Manitowoc
County areas because it is more than 10 years beyond the first 10-year
maintenance period. The 2030 emissions inventory is projected from the
EPA 2011 version 6.3 modeling platform.\10\ The relevant inventory
scenario names are ``2014fd'' and ``2028el.'' The 2028 scenario was
used in past air quality modeling for the regional haze program. WDNR
projected emissions from 2028 to 2030 for the Door County and Manitowoc
County areas based on EPA's 2028 emission inventory projections from
EPA's 6.3 modeling platform. WDNR projected that emissions for 2030
would remain at 2028 levels for the Door County and Manitowoc County
areas. WDNR's approach is conservative as emissions are expected to
further decrease from 2028 to 2030 due to decreases in mobile source
emissions through continued implementation of vehicle emissions
standard and vehicle fleet turn over. The 2030 summer day emissions
inventory for the Door County and Manitowoc County areas are summarized
in Table 11 below. Tables 12 and 13 document changes in NOX
and VOC emissions in Door County and Manitowoc County between 2007,
2014 and 2030.

In summary, the maintenance demonstration for the Door County and
Manitowoc County areas shows maintenance of the 1997 ozone standard by
providing emissions information to support the demonstration that
future emissions of NOX and VOC will remain at or below 2014
emission levels when taking into account both future source growth and
implementation of future controls. Table 12 shows VOC and
NOX emissions in Door County are projected to decrease by
3.62 tpd and 4.14 tpd, respectively, between 2014 and 2030. Table 13
shows VOC and NOX emissions in Manitowoc County are
projected to decrease by 1.16 tpd and 4.44 tpd, respectively, between
2014 and 2030.
c. Milwaukee-Racine Area
WDNR is demonstrating maintenance through 2032 for the Milwaukee-
Racine area by showing that future emissions of VOC and NOX
remain at or below attainment year emission levels. 2032 is an
appropriate maintenance year for the Milwaukee-Racine area because it
is more than 10 years beyond the first 10-year maintenance period. The
2028 emissions inventory is projected from the EPA 2011 version 6.3
modeling platform.\11\ The relevant inventory scenario names are
``2014fd'' and ``2028el.'' The 2028 scenario was used in past air
quality modeling for the regional haze program. WDNR projected
emissions from 2028 to 2032 for Milwaukee-Racine area based on EPA's
2028 emission inventory projections from EPA's 6.3 modeling platform.
WDNR projected that emissions for 2032 would remain at 2028 levels for
Milwaukee-Racine area. WDNR's approach is conservative as emissions are
expected to further decrease from 2028 to 2032 due to decreases in
mobile source emissions through continued implementation of vehicle
emissions standard and vehicle fleet turn over. The 2032 summer day
emissions inventory for the Milwaukee-Racine area is summarized in
Tables 14 and 15 below. Table 16 documents changes in NOX
and VOC emissions in the Milwaukee-Racine area between 2008, 2014 and

In summary, the maintenance demonstration for the Milwaukee-Racine
area shows maintenance of the 1997 ozone standard by providing
emissions information to support the demonstration that future
emissions of NOX and VOC will remain at or below 2014
emission levels when taking into account both future source growth and
implementation of future controls. Table 16 shows that VOC and
NOX emissions in Milwaukee-Racine area are projected to
decrease by 26.27 tpd and 63.68 tpd, respectively, between 2014 and
2032.
3. Continued Air Quality Monitoring
WDNR commits to continue to operate an approved ozone monitoring
network in Kewaunee County, Door County, Manitowoc County and the
Milwaukee-Racine area. WDNR commits to consult with EPA prior to making
changes to the existing monitoring network should changes become
necessary in the future. WDNR remains obligated to meet monitoring
requirements and continue to quality assure monitoring data in
accordance with 40 CFR part 58, and to enter all data into the Air
Quality System (AQS) in accordance with Federal guidelines.
4. Verification of Continued Attainment
WDNR has the legal authority to enforce and implement the
requirements of the maintenance plans for Kewaunee County, Door County,
Manitowoc County and the Milwaukee-Racine area. This includes the
authority to adopt, implement, and enforce any subsequent emission
control measures determined to be necessary to correct future ozone
attainment problems.
Verification of continued attainment is accomplished through
operation of the ambient ozone monitoring network and the periodic
update of the area's emissions inventory. WDNR will continue to operate
an approved ozone monitoring network in Kewaunee County, Door County,
Manitowoc County and the Milwaukee-Racine area. There are no plans to
discontinue operation, relocate, or otherwise change the existing ozone
monitoring network other than through revisions to the Wisconsin
Monitoring Network Plan approved by EPA.
In addition, to track future levels of emissions, WDNR will
continue to develop and submit to EPA updated emission inventories for
all source categories at least once every three years, consistent with
the requirements of 40 CFR part 51, subpart A, and in 40 CFR 51.122.
The Consolidated Emissions Reporting Rule (CERR) was promulgated by EPA
on June 10, 2002 (67 FR 39602). The CERR was replaced by the Annual
Emissions Reporting Requirements (AERR) on December 17, 2008 (73 FR
76539).
5. Contingency Plan
Section 175A of the CAA requires that the state must adopt a
maintenance plan, as a SIP revision, that includes such contingency
measures as EPA deems necessary to assure that the state will promptly
correct a violation of the NAAQS that occurs after redesignation of the
area to attainment of the NAAQS. The maintenance plan must identify:
The contingency measures to be considered and, if needed for
maintenance, adopted and implemented; a schedule and procedure for
adoption and implementation; and, a time limit for action by the state.
The state should also identify specific indicators to be used to
determine when the contingency measures need to be considered, adopted,
and implemented. The maintenance plan must include a commitment that
the state will implement all measures with respect to the control of
the pollutant that were contained in the SIP before redesignation of
the area to attainment in accordance with section 175A(d) of the CAA.
As required by section 175A of the CAA, WDNR has adopted
contingency plans for Kewaunee County, Door County, Manitowoc County
and the Milwaukee-Racine area to address possible future ozone air
quality problems. The contingency plans adopted by WDNR have two levels
of response: A warning level response and an action level response.
In WDNR's plans, a warning level response will be triggered when an
annual fourth high monitored value higher than the NAAQS is monitored
within the maintenance area. A warning level response will consist of
WDNR
[[Page 16598]]
conducting a study to determine whether the ozone value indicates a
trend toward higher ozone values and whether emissions are
significantly higher than projected in the maintenance plan. The study
will evaluate whether the actual emissions have deviated significantly
from the emissions projections contained in the maintenance plan for
the nonattainment areas, along with an evaluation of which sectors and
states are responsible for any emissions increases. The study will also
assess whether unusual meteorological conditions during the high-ozone
year led to the high monitored ozone concentrations. The study will
evaluate whether the trend, if any, is likely to continue and, if so,
the control measures necessary to reverse the trend. The study will
consider ease and timing of implementation as well as economic and
social impacts. The study findings will be completed no later than the
beginning of the following summer ozone control period (May 1).
Implementation of necessary controls in response to a warning level
response trigger will follow the procedures for control selection and
implementation outlined under the action level response.
In WDNR's plans, an action level response is triggered when a
three-year design value exceeding the level of the 1997 ozone NAAQS is
monitored within the maintenance area. In the event that the action
level is triggered and is not found to be due to an exceptional event,
malfunction, or noncompliance with a permit condition or rule
requirement, WDNR, in conjunction with the metropolitan planning
organization or regional council of governments, will determine what
additional control measures are needed to ensure future attainment of
the ozone standard. Control measures selected will be adopted and
implemented within 18 months of the certification of the monitoring
data that triggered the action level response. WDNR may also consider
if significant new regulations not currently included as part of the
maintenance provisions will be implemented in a timely manner and would
thus constitute an adequate contingency measure response.
WDNR included the following list of potential contingency measures
in its maintenance plans:
1. Implementation of any federally promulgated rule regulating
transport of ozone precursors;
2. Updated Federal NOX emission limits for heavy-duty
vehicles;
3. Updated (Phase 2) Federal fuel efficiency standards for medium
and heavy-duty engines and vehicles;
4. New Federal regulations on the sale of aftermarket catalysts for
vehicle catalytic converters;
5. Anti-idling control program for mobile sources, targeting diesel
vehicles;
6. Diesel exhaust retrofits;
7. Traffic flow improvements;
8. Park and ride facilities;
9. Rideshare/carpool program;
10. Expansion of the vehicle emissions testing program.
EPA has concluded that the maintenance plans adequately addresses
the five basic components of a maintenance plan required under Section
175A of the CAA: Attainment inventory, maintenance demonstration,
monitoring network, verification of continued attainment, and a
contingency plan. Thus, EPA proposes to find that the maintenance plans
SIP revision submitted by WDNR for Kewaunee County, Door County,
Manitowoc County and the Milwaukee-Racine area meet the requirements of
section 175A of the CAA.
B. Transportation Conformity
Transportation conformity is required by section 176(c) of the CAA.
Conformity to a SIP means that transportation activities will not
produce new air quality violations, worsen existing violations, or
delay timely attainment of the NAAQS (CAA 176(c)(1)(B)). EPA's
conformity rule at 40 CFR part 93 requires that transportation plans,
programs and projects conform to SIPs and establish the criteria and
procedures for determining whether they conform. The conformity rule
generally requires a demonstration that emissions from the Regional
Transportation Plan and the Transportation Improvement Program (TIP)
are consistent with the motor vehicle emissions budget (MVEB) contained
in the control strategy SIP revision or maintenance plan (40 CFR
93.101, 93.118, and 93.124). A MVEB is defined as ``that portion of the
total allowable emissions defined in the submitted or approved control
strategy implementation plan revision or maintenance plan for a certain
date for the purpose of meeting reasonable further progress milestones
or demonstrating attainment or maintenance of the NAAQS, for any
criteria pollutant or its precursors, allocated to highway and transit
vehicle use and emissions (40 CFR 93.101).''
EPA's current transportation conformity regulation requires a
regional emissions analysis only during the time period beginning one
year after a nonattainment designation for a particular NAAQS until the
effective date of revocation of that NAAQS (40 CFR 93.109(c)).
Therefore, pursuant to the conformity regulation, a regional emissions
analysis using MVEBs is not required for conformity determinations for
the 1997 ozone NAAQS because that NAAQS has been revoked (80 FR 12264).
As no regional emissions analysis is required for Kewaunee County, Door
County, Manitowoc County or the Milwaukee-Racine area, transportation
conformity for the 1997 ozone NAAQS can be demonstrated by a
Metropolitan Planning Organization and Department of Transportation for
transportation plans and TIPs by showing that the remaining criteria
contained in Table 1 in 40 CFR 93.109, and 40 CFR 93.108 have been met.
IV. Proposed Action
Under sections 110(k) and 175A of the CAA and for the reasons set
forth above, EPA is proposing to approve the Kewaunee County, Door
County and Manitowoc County, and the Milwaukee-Racine area second
maintenance plans for the 1997 Ozone NAAQS, submitted by WDNR on
December 13, 2019, as a revision to the Wisconsin SIP. These second
maintenance plans are designed to keep the Kewaunee County area in
attainment of the 1997 ozone NAAQS through 2028, Door County and
Manitowoc County in attainment of the 1997 ozone NAAQS though 2030, and
the Milwaukee-Racine area in attainment of the 1997 ozone NAAQS through
2032.
V. 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
proposed action merely proposes to approve state law as meeting Federal
requirements and does not impose additional requirements beyond those
imposed by state law. For that reason, this proposed 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
[[Page 16599]]
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 disproportionate human health or environmental effects with
practical, appropriate, 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).
