A BILL FOR

SB3934LRB103 40300 LNS 72375 b
1 AN ACT concerning safety.
2 Be it enacted by the People of the State of Illinois,
3represented in the General Assembly:
4 Section 1. References to Act. This Act may be referred to
5as the Transportation Choices Act.
6 Section 5. The Department of Transportation Law of the
7Civil Administrative Code of Illinois is amended by adding
8Section 2705-204 as follows:
9 (20 ILCS 2705/2705-204 new)
10 Sec. 2705-204. Transportation planning and greenhouse gas
11reduction.
12 (a) The General Assembly finds that:
13 (1) Article XI of the Illinois Constitution provides
14 that the public policy of the State and the duty of each
15 person is to provide and maintain a healthful environment
16 for the benefit of this and future generations.
17 (2) The transportation sector is now the largest
18 source of greenhouse gas emissions in the State.
19 (3) The State has previously set a goal to have an
20 electric power sector that is free of greenhouse gas
21 emissions by 2045.
22 (4) Greenhouse gas pollution resulting from the

SB3934- 2 -LRB103 40300 LNS 72375 b
1 production, distribution, and use of motor vehicle fuels
2 produces many social costs, including, but not limited to,
3 adverse public health impacts, increased heat waves,
4 droughts, water supply shortages, flooding, biodiversity
5 loss, and forest health issues, such as forest fires.
6 (5) The Illinois State Climatologist is projecting
7 that, by the end of the 21st Century, average daily
8 temperatures in the State will increase between 4 and 9
9 degrees Fahrenheit under a lower emissions scenario and
10 between 8 and 14 degrees Fahrenheit under a higher
11 emissions scenario.
12 (6) Climate change of such speed and magnitude will
13 result in heat stress on animals, plants, and workers;
14 reduced crop yields from short-term and rapid-onset
15 drought; increased pestilence; and other challenges that
16 will adversely affect the State's agriculture sector.
17 (7) Increases in flooding, heat, and other factors
18 associated with climate change will stress the State's
19 transportation infrastructure, such as bridges and
20 roadways in low-lying areas, and will require more
21 resources to maintain roadways and other transportation
22 infrastructure.
23 (8) State investment in a clean transportation economy
24 in the State can expand equitable access to public health,
25 safety, a cleaner environment, quality jobs, and economic
26 opportunity.

SB3934- 3 -LRB103 40300 LNS 72375 b
1 (9) It is the public policy of the State to ensure that
2 State residents from communities disproportionately
3 impacted by climate change, communities facing automotive
4 plant closures, economically disadvantaged communities,
5 and individuals experiencing barriers to employment have
6 access to State programs and good jobs and career
7 opportunities in growing sectors of the State economy.
8 (10) To minimize any adverse environmental and health
9 impacts of planned transportation projects and to address
10 inequitable distribution of the burdens of those projects,
11 it is necessary, appropriate, and in the best interests of
12 the State and its citizens to require the Department and
13 MPOs, which are the State's primary transportation
14 planning entities with responsibility for selecting and
15 funding transportation projects, to engage in an enhanced
16 level of planning, modeling, and other analysis, community
17 engagement, and monitoring with respect to those projects
18 as required by this Section.
19 (11) Subsection (a) of Section 15 of the Regional
20 Planning Act provides that the Chicago Metropolitan Agency
21 for Planning, whose Policy Committee is the MPO for
22 Northeastern Illinois, shall be responsible for developing
23 and adopting a funding and implementation strategy for an
24 integrated land use and transportation planning process.
25 (12) Section 48 of the Regional Planning Act provides
26 that the Chicago Metropolitan Agency for Planning shall

SB3934- 4 -LRB103 40300 LNS 72375 b
1 establish an incentive program to enable local governments
2 and developers to create more affordable workforce housing
3 options near jobs and transit, create jobs near existing
4 affordable workforce housing, create transit-oriented
5 development, integrate transportation and land use
6 planning, provide a range of viable transportation choices
7 in addition to the car, encourage compact and mixed-use
8 development, and support neighborhood revitalization.
9 (13) Paragraph (1) of subsection (a) of Section 5303
10 of Title 49 of the United States Code (49 U.S.C.
11 5303(a)(1)) provides, in relevant part, that it is in the
12 national interest to better connect housing and
13 employment, while minimizing transportation-related fuel
14 consumption and air pollution through metropolitan and
15 statewide transportation planning processes.
16 (14) Subparagraph (A) of paragraph (4) of subsection
17 (k) of Section 5303 of Title 49 of the United States Code
18 (49 U.S.C. 5303(k)(4)(A)) provides that MPOs serving
19 transportation management areas may address the
20 integration of housing, transportation, and economic
21 development strategies through a process that provides for
22 effective integration, based on a cooperatively developed
23 and implemented strategy, of new and existing
24 transportation facilities eligible for funding.
25 (15) Subparagraph (C) of paragraph (4) of subsection
26 (k) of Section 5303 of Title 49 of the United States Code

SB3934- 5 -LRB103 40300 LNS 72375 b
1 (49 U.S.C. 5303(k)(4)(C)) provides that MPOs serving
2 transportation management areas may develop a housing
3 coordination plan that includes projects and strategies
4 that may be considered in the metropolitan transportation
5 plan of the MPO to develop regional goals for the
6 integration of housing, transportation, and economic
7 development strategies.
8 (16) Land use policies and practices that result in
9 shorter distances between where people reside and jobs and
10 other destinations they seek to access and that facilitate
11 multimodal transportation options for the public are one
12 of the most effective tools to reduce greenhouse gas
13 emissions from the transportation sector and provide more
14 affordable transportation options.
15 (17) Transportation is the second-largest expense
16 category for most households and the cost of owning,
17 operating, and maintaining personal vehicles is a
18 significant burden for many households.
19 (18) Reducing vehicle miles traveled per person
20 through more efficient land use and transportation systems
21 will help the State achieve its greenhouse gas reduction
22 goals and reduce the transportation cost burden on State
23 households.
24 (19) To the maximum extent practicable, actions taken
25 to achieve these goals must avoid causing disproportionate
26 adverse impacts to residents of communities that are or

SB3934- 6 -LRB103 40300 LNS 72375 b

7 acceptable GHG emissions analysis; and
8 (D) the Department shall establish an appropriate
9 process, including deadlines for timely completion of
10 its review of MPO GHG emissions analyses and for
11 corrective action by MPOs where such is necessary;
12 (6) upon request of an MPO, provide the MPO with a GHG
13 emissions analysis that the MPO can use for purposes of
14 this Section in lieu of the MPO conducting its own GHG
15 emissions analysis; and
16 (7) adopt rules applicable to itself, MPOs, and
17 recipients of Department funding so the State can achieve
18 the transportation sector greenhouse gas emissions
19 reduction goals and targets set forth in subsections (c)
20 and (p) of Section 9.15 of the Environmental Protection
21 Act and administer the various processes and requirements
22 set forth in this Section.
23 (f) The Department and each MPO must use a GHG emissions
24analysis to determine if their applicable planning document
25will result in the Department or MPO meeting its GHG targets.
26If a GHG emissions analysis determines that the Department or

SB3934- 16 -LRB103 40300 LNS 72375 b
1MPO is more likely than not to fail to meet one or more of its
2GHG targets, then the Department or MPO shall identify GHG
3mitigation measures that are needed for the Department or MPO
4to meet its GHG targets as follows:
5 (1) The Department or MPO shall submit a mitigation
6 action plan that identifies GHG mitigation measures needed
7 to meet the GHG targets and that includes:
8 (A) the anticipated start and completion date of
9 each GHG mitigation measure;
10 (B) an estimate of the annual CO2e emissions
11 reductions achieved per year by the GHG mitigation
12 measure;
13 (C) an estimate of the impact of the GHG
14 mitigation measure on VMT;
15 (D) quantification of the specific co-benefits
16 from each GHG mitigation measure, including reduction
17 of copollutants, such as PM2.5 and NOx, as well as
18 travel impacts, such as changes to VMT, pedestrian or
19 bike use, and transit ridership;
20 (E) a description of any benefits to
21 disproportionately impacted communities from the GHG
22 mitigation measure, including an estimate of the total
23 amount spent on GHG mitigation measures in or designed
24 to serve disproportionately impacted communities; and
25 (F) a status report submitted annually and
26 published on its website for each GHG mitigation

SB3934- 17 -LRB103 40300 LNS 72375 b

2 concerning each GHG mitigation measure:
3 (i) availability and timing of funding;
4 (ii) implementation timeline;
5 (iii) current status;
6 (iv) for GHG mitigation measures that are in
7 progress or completed, quantification of the
8 greenhouse gas impact of such GHG mitigation
9 measures and any co-benefits or detriments; and
10 (v) for GHG mitigation measures that are
11 delayed, canceled, or substituted, an explanation
12 of why that decision was made and how these GHG
13 mitigation measures or the equivalent will be
14 achieved.
15 (2) GHG mitigation measures are sufficient if the
16 total GHG emissions reduction from the GHG mitigation
17 measures, after accounting for the GHG emissions otherwise
18 resulting from existing and planned projects in the
19 applicable planning document, results in the Department or
20 MPO meeting its GHG targets. Each comparison of GHG
21 emissions reductions and GHG targets under this subsection
22 must be performed over equal comparison periods.
23 (3) In the annual GHG mitigation measures status
24 report under subparagraph (F) of paragraph (1), the
25 Department or MPO shall certify whether its GHG mitigation
26 measures will be sufficient for the Department or MPO to

2 (g) If an applicable planning document does not meet the
3GHG targets for each compliance year even after consideration
4of any GHG mitigation measures, the Department may deem the
5applicable planning document in compliance with this Section
6and approved only if the noncompliant Department or MPO
7allocates funding to advance the achievement of the applicable
8GHG targets as follows:
9 (1) in non-MPO areas, the Department (i) shall not
10 advance a roadway capacity expansion project from its
11 applicable planning document to a STIP or TIP, (ii) shall
12 not otherwise add a roadway capacity expansion project to

3 (h) Before including a roadway capacity expansion project
4in an applicable planning document, the Department or MPO must
5perform a GHG emissions analysis of the roadway capacity
6expansion project. Following the GHG emissions analysis, the
7Department or MPO must determine if, after consideration of
8all relevant factors, including VMT and social cost of carbon
9increases in the transportation network resulting from induced
10demand, the project conforms with (i) the applicable GHG
11targets and (ii) VMT targets established under subsection (c).
12 (1) If the Department or MPO determines that the
13 roadway capacity expansion project is not in conformance
14 with items (i) and (ii), the Department or MPO must:
15 (A) alter the scope or design of the roadway
16 capacity expansion project and perform a GHG emissions
17 analysis that shows that the roadway capacity
18 expansion project meets the requirements of items (i)
19 and (ii);
20 (B) incorporate sufficient GHG mitigation measures
21 to bring the Department or MPO into compliance with
22 its GHG targets, however, in order to be effective,
23 such GHG mitigation measures must be implemented no
24 later than contemporaneously with the implementation
25 of the roadway expansion project or, if not
26 implemented contemporaneously, a GHG mitigation

SB3934- 21 -LRB103 40300 LNS 72375 b
1 measure must provide a valid GHG emissions reduction
2 after the date it is implemented; or
3 (C) halt development of the roadway capacity
4 expansion project and remove the roadway capacity
5 expansion project from all applicable planning
6 documents.
7 (2) The Department and MPOs must establish a process
8 for performing roadway capacity expansion project GHG
9 emissions analysis. A GHG emissions analysis for a roadway
10 capacity expansion project must include, but shall not be
11 limited to, estimates resulting from the project for the
12 following:
13 (A) GHG emissions over a period of 20 years or the
14 last GHG target year, whichever is later;
15 (B) a net change in VMT and social cost of carbon
16 for the transportation network after factoring in the
17 effects of induced demand; and
18 (C) consideration of additional VMT in the
19 transportation network from additional capacity
20 resulting from roadway traffic capacity expansion,
21 intelligent transportation systems, or both.
22 (3) The Department or MPO must connect any GHG
23 mitigation measures associated with the roadway capacity
24 expansion project as follows:
25 (A) within or associated with at least one of the
26 communities impacted by the roadway capacity expansion

SB3934- 22 -LRB103 40300 LNS 72375 b
1 project;
2 (B) if there is not a reasonably feasible location
3 under subparagraph (A), in areas of persistent poverty
4 or historically disadvantaged communities, as measured
5 and defined by federal law, guidance and notices of
6 funding opportunity;
7 (C) if there is not a reasonably feasible location
8 under subparagraphs (A) and (B), in the region of the
9 roadway capacity expansion project; and
10 (D) if there is not a reasonably feasible location
11 under subparagraphs (A) through (C), on a statewide
12 basis.
13 (4) The Department or MPO must develop and use a
14 process for community consultation consistent with the
15 requirements of subsection (m) in the development of GHG
16 mitigation measures that the Department or MPO uses to
17 achieve compliance with its GHG targets.
18 (5) The Department or MPO must publish an explanation
19 regarding the feasibility and rationale for each GHG
20 mitigation measure under subparagraphs (B) through (D) of
21 paragraph (3).
22 (6) GHG mitigation measures connected to a roadway
23 expansion project are sufficient if the total greenhouse
24 gas reduction from the GHG mitigation measures is at least
25 equal to the total GHG emissions resulting from the
26 roadway capacity expansion project and consistent with the

SB3934- 23 -LRB103 40300 LNS 72375 b
1 Department or MPO meeting its GHG targets.
2 (A) Each comparison under this paragraph must be
3 performed over equal comparison periods.
4 (B) To avoid double counting, once a GHG
5 mitigation measure is connected to a roadway capacity
6 expansion project, that GHG mitigation measure shall
7 not be used to offset greenhouse gases associated with
8 other roadway capacity expansion projects or other
9 projects included in an applicable planning document.
10 (7) The Department and MPOs must publish information
11 regarding roadway capacity expansion project GHG emissions
12 analyses on their websites. The information must include:
13 (A) an identification of each roadway capacity
14 expansion project; and
15 (B) for each roadway capacity expansion project, a
16 summary that includes an overview of and link to the
17 roadway capacity expansion project GHG emissions
18 analysis, the greenhouse gas impact determination by
19 the Department or MPO, the social cost of carbon added
20 by the roadway capacity expansion project, and project
21 disposition, including a review of any GHG mitigation
22 measures.
23 (i) The Department and MPOs may use a GHG mitigation
24measure as an offset against GHG emissions only after the date
25the GHG mitigation measure has been implemented.
26 (j) By January 1, 2028, and every 3 years thereafter, the

SB3934- 24 -LRB103 40300 LNS 72375 b
1Department shall prepare a comprehensive, publicly released
2report on statewide transportation greenhouse gas reduction
3accomplishments and challenges and make recommendations for
4any legislative action or State agency rulemaking that would
5assist the Department and MPOs in meeting their GHG targets.
6The report, at a minimum, shall include:
7 (1) a description of whether the Department and MPOs
8 are on track to meet their GHG targets and VMT targets;
9 (2) an assessment of State and local laws,
10 regulations, rules, and practices and recommendations for
11 modifications that would help ensure that the Department
12 and MPOs meet their GHG targets and VMT targets;
13 (3) a description of the benefits from reductions in
14 GHG emissions and copollutants in the transportation
15 sector, diversification of energy sources used for
16 transportation, and substitution of other motorized and
17 nonmotorized modes of travel for VMT currently being
18 handled by vehicles powered by internal combustion
19 engines, and other economic, environmental, and public
20 health benefits;
21 (4) a description of the compliance costs borne by the
22 Department and MPOs in meeting their GHG targets and VMT
23 targets;
24 (5) a description of the social cost of carbon
25 associated with the transportation systems for which the
26 Department and each MPO is responsible and the social cost

SB3934- 25 -LRB103 40300 LNS 72375 b
1 of carbon reductions that result from GHG mitigation
2 measures and other steps being taken by the Department and
3 each MPO to reduce GHG emissions;
4 (6) a description of whether measures taken by the
5 Department and MPOs to meet GHG targets are equitable,
6 minimize costs, and maximize the total benefits to the
7 State and its citizens; and
8 (7) a description of whether activities undertaken to
9 meet GHG targets by the Department and MPOs have unduly
10 burdened disproportionately impacted communities.
11 (k) Before including any project that has an anticipated
12cost of $30,000,000 or more (i) in an applicable planning
13document or (ii) as a GHG mitigation measure, the Department
14or MPO shall calculate a climate equity accessibility score
15for the project. The climate equity accessibility score shall
16be based on a GHG emissions analysis of the project and a
17measurement of (i) the current levels of access to jobs,
18hospitals, schools, and food by available modes of
19transportation and (ii) the current level of affordability of
20transportation in the project area. The Department and MPO
21shall then calculate a climate equity accessibility score
22based on the projected change in GHG emissions, accessibility,
23and affordability from the proposed project. Projects that
24result in relatively high reductions of GHG emissions while
25increasing access to jobs and other destinations and providing
26more affordable transportation options will receive a higher

SB3934- 26 -LRB103 40300 LNS 72375 b
1climate equity accessibility score than projects that fail to
2deliver such benefits. To advance the goals of this Section
3and optimize the use of public funds, the Department and MPOs
4shall give priority to projects with high climate equity
5accessibility scores, considering which project delivers the
6most climate equity accessibility score benefit per dollar
7invested. The Department, with the assistance of the
8Environmental Protection Agency, shall provide technical
9assistance to MPOs in fulfilling their responsibilities under
10this subsection.
11 (l) To the full extent allowed by paragraph (4) of
12subsection (k) of Section 5303 of Title 49 of the United States
13Code and other applicable laws, and to extend the existing
14authority under State law vested in the Chicago Metropolitan
15Agency for Planning to MPOs throughout the State, MPOs, with
16the full support of the Department, shall conduct housing
17coordination planning to help the Department and MPOs meet
18their GHG targets.
19 (1) MPOs shall develop housing coordination plans
20 consistent with subparagraph (C) of paragraph (4) of
21 subsection (k) of Section 5303 of Title 49 of the United
22 States Code (49 U.S.C. 5303(k)(4)(C)) to better integrate
23 housing, transportation, and economic development
24 strategies and to, among other things:
25 (A) better connect housing and employment while
26 mitigating commuting times;

SB3934- 27 -LRB103 40300 LNS 72375 b
1 (B) align transportation improvements with housing
2 needs, such as housing supply shortages, and proposed
3 housing development;
4 (C) align planning for housing and transportation
5 to address needs in relationship to household incomes
6 within the metropolitan planning area;
7 (D) expand housing and economic development within
8 the catchment areas of existing transportation
9 facilities and public transportation services when
10 appropriate, including higher-density development, as
11 locally determined;
12 (E) manage effects of VMT growth in the
13 metropolitan planning area related to housing
14 development and economic development; and
15 (F) increase the share of households with
16 sufficient and affordable access to the transportation
17 networks of the metropolitan planning area.
18 (2) MPOs shall identify the location of existing and
19 planned housing and employment and transportation options
20 that connect housing and employment.
21 (3) MPOs shall include a comparison of State,
22 regional, and local transportation plans in the region to
23 land use management plans, including zoning plans, that
24 may affect road use, public transportation ridership, and
25 housing development.
26 (4) In their housing coordination planning, MPOs shall

SB3934- 28 -LRB103 40300 LNS 72375 b
1 focus on the effect that land use policies and practices,
2 such as minimum parking requirements and exclusionary
3 zoning requirements, contribute to increases in VMT and
4 GHG emissions and consider how such policies affect
5 housing and transportation affordability.
6 (5) MPOs shall outline recommendations for land use
7 policies and best practices that have the effect of
8 increasing the affordability of housing and transportation
9 and reducing GHG emissions.
10 (6) The Department shall assist MPOs in their housing
11 coordination planning and make best efforts to align the
12 Department's planning and project programming with MPO
13 efforts to encourage land use policies and best practices
14 that have the effect of increasing the affordability of
15 housing and transportation, improving accessibility to
16 destinations, and reducing GHG emissions.
17 (7) The Department shall not advance to the STIP a
18 project in a metropolitan planning area that the MPO has
19 determined would conflict with its housing coordination
20 plan prepared under paragraph (1) or would have the effect
21 of decreasing the affordability of transportation or the
22 accessibility of destinations or of increasing GHG
23 emissions.
24 (8) In furtherance of Section 48 of the Regional
25 Planning Act, the Department and MPOs shall adopt
26 performance-based methods for allocating discretionary

SB3934- 29 -LRB103 40300 LNS 72375 b
1 funds that reward jurisdictions that have adopted land use
2 policies and practices associated with increasing the
3 affordability of housing and transportation, improving
4 accessibility to destinations, and reducing GHG emissions.
5 (A) The Department and MPOs may build on the
6 climate equity accessibility scoring tool developed
7 under subsection (k) or develop a separate tool for
8 identifying jurisdictions that have adopted land use
9 policies and practices associated with increasing the
10 affordability of housing and transportation, improving
11 accessibility to destinations, and reducing GHG
12 emissions.
13 (B) The Department and MPOs shall publicly
14 describe the methodology they use in allocating
15 discretionary funding under this paragraph.
16 (C) When allocating discretionary funding, the
17 Department and MPOs shall give at least equal weight
18 to land use policies and practices that facilitate
19 reductions in GHG emissions that they give to existing
20 factors, such as congestion relief, safety, and
21 traffic operations.
22 (D) The Department and MPOs shall consider land
23 use policies and practices as provided in this
24 subsection when allocating discretionary funding from
25 every source.
26 (9) When evaluating all projects for possible

SB3934- 30 -LRB103 40300 LNS 72375 b
1 inclusion in applicable planning documents or in a STIP or
2 TIP, the Department and MPOs shall adopt performance-based
3 project selection methods that give priority to projects
4 located in jurisdictions that have adopted land use
5 policies and practices associated with increasing the
6 affordability of housing and transportation, improving
7 accessibility to destinations, and reducing GHG emissions.
8 (10) This subsection shall not diminish or restrict
9 the existing authority of jurisdictions over their land
10 use policies and practices.
11 (m) The Department and MPOs shall provide early and
12continuous opportunities for public participation in the
13transportation planning process. The process shall be
14proactive and provide timely information, adequate public
15notice, reasonable public access, and opportunities for public
16review and comment at key decision points in the process. The
17objectives of public participation in the transportation
18planning process include providing a mechanism for public
19perspectives, needs, and ideas to be considered in the
20planning process; developing the public's understanding of the
21problems and opportunities facing the transportation system;
22demonstrating explicit consideration and response to public
23input through a variety of tools and techniques; and
24developing a consensus on plans. The Department shall develop
25a documented public participation process under 23 CFR 450.
26 (1) Under 23 CFR 450, Subpart B, the Department is

10 necessary, the Department or MPO shall revise their
11 public participation practices in the transportation
12 planning process and allow time for public review and
13 comment per 23 CFR 450.
14 (n) Beginning on January 1, 2025, each applicable planning
15document from the Department or MPO must include a
16consolidated and comprehensive list of all project types to be
17funded using any federal, State, or local funding source,
18including bicycle, pedestrian, bus, rail, and roadway
19projects, and shall include a summary of planned expenditures
20by project type.
21 (o) Beginning September 30, 2025, the Department and MPOs
22shall establish a social cost of carbon and use the social cost
23of carbon in their applicable planning documents and other
24planning activities.
25 (1) The social cost of carbon shall serve as a
26 monetary estimate of the value of not emitting a ton of GHG

SB3934- 35 -LRB103 40300 LNS 72375 b
1 emissions.
2 (2) In developing the social cost of carbon applicable
3 to the projects and programs in their applicable planning
4 documents and for other planning and project programming
5 activities, the Department and MPOs shall consider the
6 social cost of carbon established by the Environmental
7 Protection Agency under subsection (q) of Section 9.15 of
8 the Environmental Protection Act and may consider prior or
9 existing estimates of the social cost of carbon issued or
10 adopted by the federal government, appropriate
11 international bodies, or other appropriate and reputable
12 scientific organizations.
13 (3) The Department may adopt the social cost of carbon
14 established by the Environmental Protection Agency under
15 subsection (q) of Section 9.15 of the Environmental
16 Protection Act or establish its own social cost of carbon
17 through the process set forth in paragraphs (1) and (2),
18 but the Department shall not adopt a social cost of carbon
19 that is lower than that established by the Environmental
20 Protection Agency.
21 (4) MPOs may adopt the social cost of carbon
22 established by the Environmental Protection Agency under
23 subsection (q) of Section 9.15 of the Environmental
24 Protection Act or by the Department under paragraph (3) or
25 establish their own social cost of carbon through the
26 process set forth in paragraphs (1) and (2), but an MPO

SB3934- 36 -LRB103 40300 LNS 72375 b
1 shall not adopt a social cost of carbon that is lower than
2 that established by the Environmental Protection Agency or
3 the Department.
4 (5) The Department shall incorporate the social cost
5 of carbon into its assessment of projects for possible
6 inclusion in its applicable planning document or for
7 inclusion in a STIP or TIP, giving priority to projects
8 that have a relatively low social cost of carbon:
9 (A) The Department shall not include any project
10 over $30,000,000 in an applicable planning document or
11 a STIP or TIP unless it has calculated the social cost
12 of carbon resulting from the project over the useful
13 life of the project.
14 (B) Such calculations shall result in an estimate
15 of the social cost of carbon under a no-build scenario
16 and an estimate of the social cost of carbon if the
17 project is built, factoring in the effects of induced
18 demand and other appropriate factors.
19 (C) The estimate of the social cost of carbon must
20 include total additional GHG emissions attributable to
21 the proposed project and shall not be limited to GHG
22 emissions from within the physical boundaries of the
23 project.
24 (D) The Department shall publish in applicable
25 planning documents and STIPs the no-build and build
26 estimates of the social cost of carbon for each

SB3934- 37 -LRB103 40300 LNS 72375 b
1 project for which an estimate of the social cost of
2 carbon has been prepared.
3 (E) For purposes of its planning processes under
4 Sections 2705-200, 2705-203, and 2705-205, and after
5 factoring in the effects of induced demand on VMT
6 attributable to a proposed project, the Department
7 shall offset the social cost of carbon and the social
8 cost of crashes attributable to a project against its
9 projections of the value of the time savings from any
10 reduction in congestion attributable to the project
11 and shall publish its calculations and results.
12 (F) The Department may rely upon estimates of the
13 social cost of carbon prepared by MPOs for projects
14 included in a STIP that are located inside the MPO's
15 boundaries only if the Department finds that those
16 estimates of the social cost of carbon are based on
17 reasonable assumptions and methodology.
18 (6) Each MPO shall incorporate the social cost of
19 carbon into its assessment of projects for possible
20 inclusion in its applicable planning document or for
21 inclusion in a TIP, giving priority to projects that have
22 a relatively low social cost of carbon:
23 (A) An MPO shall not include any project over
24 $30,000,000 in a TIP unless it has calculated the
25 social cost of carbon resulting from the project over
26 the useful life of the project.

SB3934- 38 -LRB103 40300 LNS 72375 b
1 (B) Such calculations shall result in an estimate
2 of the social cost of carbon under a no-build scenario
3 and an estimate of the social cost of carbon if the
4 project is built, factoring in the effects of induced
5 demand and other appropriate factors.
6 (C) The estimate of the social cost of carbon must
7 include total additional GHG emissions attributable to
8 the proposed project and shall not be limited to GHG
9 emissions from within the physical boundaries of the
10 project.
11 (D) Each MPO shall publish in its applicable
12 planning documents and TIPs the no-build and build
13 estimates of the social cost of carbon for each
14 project for which an estimate of the social cost of
15 carbon has been prepared.
16 (E) For purposes of its planning processes, and
17 after factoring in the effects of induced demand on
18 VMT attributable to a proposed project, an MPO shall
19 offset the social cost of carbon and the social cost of
20 crashes attributable to a project from its projection
21 of the value of the time savings from any reduction in
22 congestion attributable to the project and shall
23 publish its calculations and results.
24 (F) An MPO may rely upon the estimate of the social
25 cost of carbon prepared by the Department for projects
26 included in a TIP only if the MPO finds that the

SB3934- 39 -LRB103 40300 LNS 72375 b
1 Department's estimates of the social cost of carbon
2 are based on reasonable assumptions and methodologies.
3 (p) By no later than January 1, 2025, the Department shall
4convene a Greenhouse Gas in Transportation Working Group.
5 (1) The Working Group shall assist the Department and
6 MPOs with:

11transmission operators determine that a reliability violation
12will occur during the time frame the study is evaluating, then
13the Illinois Power Agency, in conjunction with the
14Environmental Protection Agency shall develop a plan to reduce
15or delay CO2e and copollutant emissions reductions
16requirements only to the extent and for the duration necessary
17to meet the resource adequacy and reliability needs of the
18State, including allowing any plants whose emission reduction
19deadline has been identified in the plan as creating a
20reliability concern to continue operating, including operating
21with reduced emissions or as emergency backup where
22appropriate. The plan shall also consider the use of renewable
23energy, energy storage, demand response, transmission
24development, or other strategies to resolve the identified
25resource adequacy shortfall or reliability violation.

16 specific alternative wording or proposals. All comments
17 shall be posted on the Environmental Protection Agency's,
18 the Illinois Power Agency's, and the Illinois Commerce
19 Commission's websites. Within 30 days following the end of
20 the 60-day review period, the Environmental Protection
21 Agency and the Illinois Power Agency shall revise the plan
22 as necessary based on the comments received and file its
23 revised plan with the Illinois Commerce Commission for
24 approval.

14 reliability deficiency identified in the reliability
15 mitigation plan at the least amount of CO2e and copollutant
16 emissions, taking into consideration the emissions impacts
17 on environmental justice communities, and that it will
18 ensure adequate, reliable, affordable, efficient, and
19 environmentally sustainable electric service at the lowest
20 total cost over time, taking into account the impact of
21 increases in emissions.
22 (4) If the resource adequacy or reliability deficiency
23 identified in the reliability mitigation plan is resolved
24 or reduced, the Environmental Protection Agency and the
25 Illinois Power Agency may file an amended plan adjusting
26 the reduction or delay in CO2e and copollutant emission
