EXECUTIVE SUMMARY
As part of its transportation planning process, the Michigan
Department of Transportation (MDOT) completed the
transportation conformity process for the new 2023-2026 State
Transportation Improvement Program (STIP).
This report documents that the 2023-2026 STIP in Benzie County
meets the federal transportation conformity requirements in 40
CFR Part 93 subpart A.
Clean Air Act (CAA) section 176(c) (42 U.S.C. 7506(c)) requires
that federally funded or approved highway and transit activities
are consistent with (“conform to”) the purpose of the State
Implementation Plan (SIP). Conformity to the purpose of the SIP
means that transportation activities will not cause or contribute to
new air quality violations, worsen existing violations, or delay
timely attainment of the relevant national ambient air quality
standard (NAAQS) or any interim milestones, 42 U.S.C.
7506(c)(1). The United States Environmental Protection Agency’s
(EPA) transportation conformity rules establish the criteria and
procedures for determining whether Metropolitan Transportation
Plans (MTP), TIPs, and federally supported highway and transit
projects conform to the SIP, 40 CFR Parts 51.390 and 93 subpart A.
On Feb. 16, 2018, the United States Court of Appeals for the
District of Columbia Circuit in South Coast Air Quality Mgmt.
District v. EPA (“South Coast II,” 882 F.3d 1138) held that
transportation conformity determinations must be made in areas
that were either nonattainment or maintenance for the 1997 ozone
NAAQS and attainment for the 2008 ozone NAAQS when the
1997 ozone NAAQS was revoked. These conformity
determinations were required in these areas after Feb. 16, 2019.
Benzie County was in maintenance at the time of the 1997 ozone
NAAQS revocation on April 6, 2015, and was also designated
attainment for the 2008 ozone NAAQS on May 21, 2012. It was
also designated attainment for the 2015 ozone NAAQS on Jan. 16,
2018. Therefore, per the South Coast II decision, this conformity
determination is being made for the 1997 ozone NAAQS on the
STIP.

This conformity determination was completed consistent with
CAA requirements, existing associated regulations at 40 CFR
Parts 51.390 and 93 subpart A, and the South Coast II decision,
according to EPA’s Transportation Conformity Guidance for the South
Coast II Court Decision issued on Nov. 29, 2018.

1.0 BACKGROUND
1.1 TRANSPORTATION CONFORMITY PROCESS
The concept of transportation conformity was introduced in the
CAA of 1977, which included a provision to ensure that
transportation investments conform to a SIP for meeting the
federal air quality standards. Conformity requirements were
made substantially more rigorous in the CAA Amendments of
1990. The transportation conformity regulations that detail
implementation of the CAA requirements were first issued in
November 1993 and have been amended several times. The
regulations establish the criteria and procedures for
transportation agencies to demonstrate that air pollutant
emissions from LRTPs, TIPs, and projects are consistent with
(“conform to”) the state’s air quality goals in the SIP. This
document has been prepared for state and local officials who are
involved in decision-making on transportation investments.
Transportation conformity is required under CAA Section 176(c)
to ensure that federally supported transportation activities are
consistent with (“conform to”) the purpose of a state’s SIP.
Transportation conformity establishes the framework for
improving air quality to protect public health and the
environment. Conformity to the purpose of the SIP means Federal
Highway Administration (FHWA) and Federal Transit
Administration (FTA) funding and approvals are given to
highway and transit activities that will not cause new air quality
violations, worsen existing air quality violations, or delay timely
attainment of the relevant air quality standard, or any interim
milestone.

1.2 CONFORMITY AREA
The conformity area consists of Benzie County, which is an
isolated rural conformity area only covered by the STIP.
Findings of the transportation conformity report are for
transportation activities contained within the conformity area.
1.3 ATTAINMENT STATUS
On April 15, 2004, the EPA issued final designations of areas not
attaining the 1997 ozone NAAQS. Benzie County was designated
a nonattainment area.
On May 16, 2007, the EPA redesignated the area attainment,
approving and finding adequate motor vehicle emissions budgets
for volatile organic compounds (VOC) and nitrogen oxides (NOx)
for the year 2018. The area was placed into maintenance; this
requires conformity emissions to be compared to the motor
vehicle emission budgets contained in the SIP.
On July 20, 2012, the EPA designated all of Michigan as
attainment for the strengthened 2008 ozone NAAQS.
On July 20, 2013, the EPA partially revoked the 1997 ozone
NAAQS, revoking the requirement to do transportation
conformity for areas that were in maintenance.
On April 6, 2015, the EPA completely revoked the 1997 ozone
NAAQS, which resulted in removal of all transportation
conformity requirements.
On April 23, 2018, FHWA began requiring areas in the country to
conduct conformity if they were a maintenance area for the 1997
ozone NAAQS and attainment for the 2008 ozone NAAQS when
the 1997 ozone NAAQS was revoked. This was to comply with
the court’s decision in South Coast II. The Benzie County
Draft for Public Comment
7
conformity area was one of these areas. Later, this was amended
to require MPOs to have a conformity in place on Feb. 16, 2019,
and conduct conformity going forward.
On Jan. 16, 2018, the EPA designated Benzie County as attainment
for the strengthened 2015 ozone NAAQS.
On March 6, 2020, the EPA published a final rule effective April 6,
2020, that the Benzie County 1997 ozone maintenance area's
second maintenance period will be a limited maintenance plan.
Limited maintenance plan areas must show the design value to be
well below the NAAQS and the area's levels of air quality are
unlikely to violate the NAAQS in the future. Areas with limited
maintenance plans are not required to conduct emission modeling
for conformity.
2.0 METROPOLITAN TRANSPORTATION PLAN, OR LONG-RANGE TRANSPORTATION
PLAN
The MTP, also referred to as an LRTP, is developed by the MPO
to establish a long-term transportation plan. An MTP is federally
required for MPOs to receive federal funding and must provide a
20-year (or longer) horizon. Plans are required to be updated
every four to five years. The purpose of an MTP is to assess future
needs of the area’s transportation system and set goals to meet
those needs. The planning process can enhance quality of life by
fostering the mobility of people and freight in an effective and
safe method. Benzie County is not covered by an MPO and the
State LRTP does not have projects like an MTP. This conformity
determination is for the new 2023 to 2026 STIP.
3.0 TRANSPORTATION IMPROVEMENT PROGRAM
The TIP is a financially constrained four-year program covering
the most immediate implementation priorities for transportation
projects and strategies from the MTP.
Draft for Public Comment
8
The TIP identifies proposed projects developed by local agencies
in accordance with the joint regulations of the FHWA and the
FTA. These regulations establish the TIP as the programming
phase of the overall continuing, comprehensive, and cooperative
planning process. This planning process includes local
jurisdictions, transit agencies, and state and federal transportation
officials.
Findings of this transportation conformity report are for
transportation activities contained within the conformity area.
The state is developing a new 2023 to 2026 STIP. This conformity
report is to ensure the new STIP in the Benzie County limited
orphan maintenance area satisfies its obligation to the CAA. This
report evaluates transportation activities contained in:
STIP projects in Benzie County.
4.0 TRANSPORTATION CONFORMITY DETERMINATION: GENERAL PROCESS
Per the court’s decision in South Coast II, beginning Feb. 16, 2019, a
transportation conformity determination for the 1997 ozone
NAAQS will be needed in 1997 ozone NAAQS nonattainment
and maintenance areas identified by EPA
1
for certain
transportation activities, including updated or amended MTPs
and TIPs. Conformity is required in isolated rural maintenance
areas only when a non-exempt project is determined. This
conformity determination report will address transportation
conformity for the new 2023-2026 STIP in Benzie County.
5.0 TRANSPORTATION CONFORMITY REQUIREMENTS

The areas identified can be found in EPA’s “Transportation Conformity Guidance for the South Coast II Court
Decision," EPA-420-B-18-050, available on the web at

5.1 OVERVIEW
On Nov. 29, 2018, EPA issued the Transportation Conformity
Guidance for the South Coast II Court Decision
2
(EPA-420-B-18-
050, November 2018) that addresses how transportation
conformity determinations can be made in areas that were
nonattainment or maintenance for the 1997 ozone NAAQS when
the 1997 ozone NAAQS was revoked but were designated
attainment for the 2008 ozone NAAQS in EPA’s original
designations for this NAAQS (May 21, 2012). The area was
designated attainment for the 2008 ozone NAAQS on May 21,
2012, and Jan. 18, 2018, for the 2015 ozone NAAQS.
The transportation conformity regulation at 40 CFR 93.109 sets
forth the criteria and procedures for determining conformity. The
conformity criteria for MTPs and TIPs include: latest planning
assumptions (93.110), latest emissions model (93.111),
consultation (93.112), transportation control measures (93.113(b)
and (c)), and emissions budget and/or interim emissions (93.118
and/or 93.119).
For the 1997 ozone NAAQS areas, transportation conformity for
MTPs and TIPs for the 1997 ozone NAAQS can be demonstrated
without a regional emissions analysis, per 40 CFR 93.109(c). This
provision states that the regional emissions analysis requirement
applies one year after the effective date of EPA’s nonattainment
designation for an NAAQS and until the effective date of
revocation of such NAAQS for an area. The 1997 ozone NAAQS
revocation was effective on April 6, 2015, and the South Coast II
court upheld the revocation. As no regional emission analysis is
required for this conformity determination, there is no
requirement to use the latest emissions model, or budget or
interim emissions tests.
Therefore, transportation conformity for the 1997 ozone NAAQS
for the 2023-2026 STIP in Benzie County can be demonstrated by

showing the remaining requirements in Table 1 in 40 CFR 93.109
have been met. These requirements, which are laid out in Section
2.4 of EPA’s guidance and addressed below, include:
Latest planning assumptions (93.110),
Consultation (93.112),
Transportation Control Measures (93.113), and
Fiscal constraint (93.108).
5.2 LATEST PLANNING ASSUMPTIONS
The use of latest planning assumptions in 40 CFR 93.110 of the
conformity rule generally apply to regional emissions analysis. In
the 1997 ozone NAAQS areas, the use of the latest planning
assumptions requirement applies to assumptions about
transportation control measures (TCMs) in an approved SIP.
The Michigan SIP does not include any TCMs (see also Section
5.4).
5.3 CONSULTATION REQUIREMENTS
The consultation requirements in 40 CFR 93.112 were addressed
both for interagency consultation and public consultation.
Interagency consultation was conducted with the Michigan
Department of Transportation (MDOT), the Michigan Department
of Environment, Great Lakes, and Energy (EGLE), FHWA, FTA,
and EPA. A summary of the Michigan Transportation Interagency
Workgroup (MITC-IAWG) meeting on April 15, 2022, and
relevant interagency consultation correspondence related to this
conformity is in Appendix A. Interagency consultation was
conducted consistent with Michigan’s conformity SIP.
Public consultation will be conducted consistent with planning
rule requirements in 23 CFR 450. The Public Participation Plan
adopted by MDOT for the STIP establishes the procedures by
which MDOT reaches the affected public agencies and the public.
The same procedures were followed for this document, ensuring
the public has an opportunity to review and comment.

A formal public comment period for this draft conformity report
was held from July 15 to Aug. 15, 2022. Public comments received
and responses to those comments are in Appendix B.
5.4 TIMELY IMPLEMENTATION OF TRANSPORTATION CONTROL MEASURES
The Michigan SIP does not include any TCMs.
5.5 FISCAL CONSTRAINT
Transportation conformity requirements in 40 CFR 93.108 state
that transportation plans and TIPs must be fiscally constrained
consistent with the metropolitan planning regulations at 23 CFR
part 450. The 2023-2026 STIP is fiscally constrained, as
demonstrated in:
2023-2026 STIP for Benzie County.
6.0 CONCLUSION
The conformity determination process completed for the 2023-
2026 STIP for Benzie County demonstrates that these planning
documents meet the CAA and Transportation Conformity rule
requirements for the 1997 ozone NAAQS.

A new State Transportation Improvement Program (STIP) is being created for
years 2023 to 2026 and the group needs to review these projects for air quality
conformity.
The staff of the Michigan Department of Transportation (MDOT) has reviewed the projects in the
attached file and have determined one project in Benzie County is non-exempt, it is a center turn lane
over a mile, per the policies for reviewing projects by the MITC-IAWG. This project will require a
conformity report for the county. All other projects are exempt. Each county has a separate tab on
the attached spreadsheet.
Please review the projects and reply, using reply to all, to this email with “concur” if you agree
with the recommendations.
Clarification or questions can be directed to me or the group.
Responses are requested by close of business Friday April 22, 2022.
