DRAFT Regional Conformity Analysis & Tri-Cities 2035 LRTP and FY 12-15 TIP Eecutive Summary In compliance with the federal transportation conformity rule (40 CFR Parts 51 and 93) and the corresponding state conformity regulation (9 VAC 5-151), this report presents the air quality conformity assessment for the Fiscal Year (FY) 2012-2015 Transportation Improvement Program (TIP) and 2035 Long Range Transportation Plan (LRTP) developed by the and Tri-Cities Metropolitan Planning Organizations (MPO). The conformity demonstration applies to the, Virginia area, which was re-designated to attainment for the 8-hour ozone national ambient air quality standard (72 FR 30485, effective June 18, 2007). The re-designated area was made subject to a concurrently-approved air quality maintenance plan, however, so federal conformity requirements still apply. The maintenance area includes the counties of Hanover, Henrico, Charles City, Prince George and Chesterfield, the cities of Colonial Heights, Hopewell, Petersburg, and, and the town of Ashland. As indicated in Table ES-1, the 2035 LRTP and FY 12-15 TIP meet all applicable requirements of the federal and state transportation conformity rules. A recommendation for a finding of conformity for the TIP and LRTP is therefore made, but is conditional upon any further and separate review as may be required by the US DOT for the fiscal constraint criterion consistent with Section 93.108 of the federal conformity rule and the requirements of federal planning regulations specified at 23 CFR Part 450. Table ES-1: Conformity Criteria Summary* Section Criteria Demonstrated for the: LRTP TIP 93.108 Fiscal constraint Yes** Yes** 93.110 Latest planning assumptions Yes Yes 93.111 Latest emissions model Yes Yes 93.112 Consultation Yes Yes 93.113(b) & (c) TCMs na*** na*** 93.118 Emissions Budget Yes Yes * As specified in the federal conformity rule at 40 CFR 93.109, Table 1 Conformity Criteria, with the addition of fiscal constraint as required in Section 93.108. ** As indicated by MPO approval of the project list and amendments for the TIP and documented with those reports, and subject to federal review consistent with 23 CFR Part 450 as referenced in Section 93.108. *** The applicable implementation (maintenance) plan for does not include transportation control measures (TCMs), and therefore they are not required for the conformity analysis or determination. See 72 FR 30485, effective June 18, 2007. The criteria listed in Table ES-1 are reviewed in turn below. Key sections of the main report are referenced where supporting documentation for the demonstration may be found. Draft Report, May 2012 i

DRAFT Regional Conformity Analysis - & Tri-Cities 2035 LRTP and FY 12-15 TIP Section 93.108: This section states: Transportation plans and TIPs must be fiscally constrained consistent with [US Dept. of Transportation] DOT s planning regulations at 23 CFR Part 450 in order to be found in conformity. The MPO documents fiscal constraint with the development of the LRTP and TIP, and includes specific sections or chapters addressing cost estimates and financial constraint. For the purposes of this conformity demonstration, therefore, fiscal constraint is indicated by MPO approval of the project lists for the FY 12-15 TIP and 2035 LRTP, and the documentation provided with those reports. A recommendation for a finding of conformity is therefore made, but is conditional upon any further and separate review as may be required by the US DOT for the fiscal constraint criterion consistent with Section 93.108 of the federal conformity rule as well as requirements of federal planning regulations specified at 23 CFR Part 450. 93.110 Criteria and procedures: Latest planning assumptions: o 93.110(a) Latest Planning Assumptions: This section requires that: the conformity determination must be based upon the most recent planning assumptions in force at the time the conformity analysis begins... In general, the latest available and approved population and employment forecasts for 2035 by Traffic Analysis Zone (TAZ) were employed with the regional travel demand network model (Cube) to generate the traffic volume and vehicle-milestraveled (VMT) forecasts applied in this conformity analysis. Regional roadway and transit networks were updated as appropriate using the Plan and Program project lists, which were subjected to interagency consultation as described below. Emission controls assumed for the analysis were consistent with those specified in the applicable implementation (maintenance) plan revision. All of the latest planning assumptions and other aspects of the conformity analysis were reviewed by the Interagency Consultation Group (ICG) at the beginning of the conformity analysis process, as documented in the chapter on consultation and in Appendi D. Additional details are provided below. o 93.110 (b) Socioeconomic Forecasts: This section requires that Assumptions must be derived from the estimates of current and future population, employment, travel, and congestion most recently developed by the MPO or other agency authorized to make such estimates and approved by the MPO. Further, Section 93.122(b)(1)(ii) requires that Land use, population, employment, and other network-based travel model assumptions must be documented and based on the best available information. Section 93.122(b)(1)(iii) adds that Scenarios of land development and use must be consistent with the future transportation system alternatives for which emissions are being estimated. As documented in the main report, the socioeconomic forecasts for 2035 (including interim years and sub-allocations as appropriate) represent the latest projections available and approved for use with the 2035 LRTP. o 93.110(c) and (d) Transit: These sections respectively require that The conformity determination for each transportation plan and TIP must discuss how transit operating policies (including fares and service levels) and assumed transit ridership has changed since the previous conformity determination and The conformity Draft Report, May 2012 ii

DRAFT Regional Conformity Analysis - & Tri-Cities 2035 LRTP and FY 12-15 TIP determination must include reasonable assumptions about transit service and increases in transit fares and road and bridge tolls over time. Transit operating policies (including fares and service levels) and modeling for transit (ridership) have not changed significantly since the previous conformity determination. Transit service is included in future networks for the region. While future transit ridership is effectively determined in the course of modeling for the conformity analysis, details on current transit operating policies including fares and service levels may be found on the Greater Transit Company (GRTC) and Petersburg Area Transit (PAT) websites 1. Transit service and fares as well as road tolls are also addressed in supporting documentation for the LRTP and associated modeling. o 93.110(e) Transportation Control Measures (TCMs) and Other Measures: This section requires that The conformity determination must use the latest eisting information regarding the effectiveness of the TCMs [transportation control measures] and other implementation plan measures which have already been implemented. The applicable SIP revision (maintenance plan) for the maintenance area does not include transportation control measures (TCMs). TCMs are therefore not required for the conformity analysis or determination. Accordingly, credit for TCMs was not taken in this analysis. See 72 FR 30490, effective June 18, 2007. 93.111 Criteria and procedures: Latest emissions model 2 : o On March 2, 2010, EPA officially released the net generation Motor Vehicle Emission Simulator (MOVES2010) model for use in SIP development and regional conformity applications 3. The EPA notice indicated that a two-year grace period (ending March 2, 2012) will apply for use of the new model in regional emissions analyses for transportation conformity determinations. On February 27 th 2012 the EPA etended the two year grace period adding another year. Therefore, for regional conformity analyses initiated before or within the three-year grace period, the MOBILE6.2 model (the model previously designated as the official model by EPA) may continue to be applied. The selection of latest emission model for the conformity analysis was considered by the ICG at the beginning of the conformity analysis process, as documented in the chapter on consultation and in Appendi D. The consensus of the ICG was to apply the MOBILE6.2 model for this analysis, as we are still within the grace period. The MOVES model may be applied in future analyses 1 2 3 See www.ridegrtc.org and http://www.petersburg-va.org/transit/patgrtc.htm, respectively.

DRAFT Regional Conformity Analysis - & Tri-Cities 2035 LRTP and FY 12-15 TIP once appropriate steps have been taken, within the grace period, to review and update as needed the applicable budgets specified in the maintenance plan. 93.112 Criteria and procedures: Consultation. Until the implementation plan revision required by 51.390 of this chapter is fully approved by EPA, the conformity determination must be made according to 93.105 (a)(2) and (e) and the requirements of 23 CFR Part 450. The Conformity SIP required by 51.390 was approved by EPA and published in the Federal Register on vember 20, 2009 (See 73 FR 223 with an effective date of January 19, 2010). The consultation requirements in the conformity SIP are generally consistent with the Federal Transportation Conformity Rule, although it also requires consultation with the Lead Planning Organization (LPO) established pursuant to Section 174 of the federal Clean Air Act as amended (CAA). The Metropolitan Air Quality Committee is the designated LPO for the region. Involvement of the VDEQ staff representative for that Committee in the local inter-agency consultation process for conformity is considered to fulfill that requirement. o The consultation procedures employed follow the requirements outlined in 93.105(a)(2) and (e), 9 VAC 5-151, and the requirements of 23 CFR Part 450. The consultation conducted for this conformity analysis is documented in detail in Chapter 3 with meeting and related materials including minutes copied in Appendi D. That consultation is summarized below: o o As noted in Chapter 3, documentation of the consultation conducted including the ICG membership list, meeting agenda and presentation materials, schedule, handouts, and minutes is provided in Appendi D. An opportunity for public input was provided at the ICG meeting held at the beginning of the conformity analysis process at which the conformity methodology, schedule and project lists were presented. Project lists as finalized following consultation are presented in Appendi E. Further, the consultation conducted for this conformity analysis followed the and Tri-Cities MPO approved Interagency Consultation Group Procedures. 93.113 Criteria and procedures: Timely implementation of TCMs. The transportation plan, TIP must provide for the timely implementation of TCMs from the applicable implementation plan Paragraph (b) identifies specific requirements for plans, and paragraph (c) for TIPs. o TCMs were not included in the applicable implementation plan or revision for the maintenance area for the 8-hour ozone standard. The criteria may therefore be considered as not applicable or as satisfied without further action for this area. 93.118 - Criteria and procedures: Motor vehicle emissions budget. (a) The transportation plan, TIP must be consistent with the motor vehicle emissions budget(s) specified in the applicable implementation plan This criterion is satisfied if it is demonstrated that emissions of the pollutants are less than or equal to the motor vehicle emissions budget(s) : (b) Consistency with the motor vehicle emissions budget(s) must be demonstrated for each year for which the applicable implementation plan specifically establishes motor vehicle emissions budget(s), for the attainment year (if it is within the timeframe of the transportation plan), for the last year of the transportation plan s forecast period, and for any intermediate years as necessary so that the years for which consistency is demonstrated are no more than ten years apart Draft Report, May 2012 iv

DRAFT Regional Conformity Analysis - & Tri-Cities 2035 LRTP and FY 12-15 TIP (c) Consistency with the motor vehicle emissions budget(s) must be demonstrated for each pollutant for which the area is in nonattainment or maintenance and for which the applicable implementation plan establishes a motor vehicle emissions budget. (d) Consistency with the motor vehicle emission budget(s) must be demonstrated by including emissions from the entire transportation system o The applicable implementation plan is the maintenance plan for the 8-hour ozone standard approved and made effective by EPA as of June 18, 2007, which established motor vehicle emission budgets for VOC and NO for the years 2011 and 2018. As documented above, total VOC and NO emissions associated with the regional transportation system as planned and programmed in the 2035 LRTP and FY 12-15 TIP for all analysis years have been modeled and demonstrated to be consistent with (i.e., less than) the motor vehicle emission budgets established in the maintenance plan for those pollutants for all years modeled. The years selected for analysis are consistent with the requirements of this section of the conformity rule. The maintenance plan specifies budgets for 2011 and 2018, and years for which budgets are established are required to be analyzed. Additionally, the conformity rule requires modeling for the last year of the transportation plan (2035), and that years modeled be no more than ten years apart. To meet the latter requirement, the year 2028 was selected. The motor vehicle emissions budget criterion is therefore met. Applicable budgets and the selection of years for modeling are reviewed in Chapters 1 and 2. Other related requirements that were not specifically included as criteria in Table ES1 - Conformity Criteria (Section 93.109) are reviewed below: 93.122 Procedures for determining regional transportation-related emissions. o All applicable requirements of this section were met, as documented in Chapter 2, including: (a) (1) all regionally significant projects included in the LRTP and TIP were included in the regional emissions analysis ; (6) ambient temperatures used in the conformity analysis are consistent with those used to establish the emission budget in the applicable implementation plan (and, similarly, relative humidity data and average barometric pressure as applied are consistent); and (7) reasonable methods were applied to estimate VMT on off-network roadways, (b) (1) A regional network model was applied. Land use, population, employment and other assumptions were documented and based on the best available information. Assumed land use development is consistent with the future transportation system. A capacity sensitive assignment methodology was applied, and (via the postprocessor) emission estimates are based on speeds derived from final assigned volumes. Zonal travel impedances are in reasonable agreement with the final assigned volumes. The model is reasonably sensitive to changes in times, costs and other factors affecting travel choices; (2) reasonable methods were applied to estimate traffic speeds sensitive to estimated volumes on each roadway segment; (3) The network model was reconciled to HPMS data for the base year. Draft Report, May 2012 v

DRAFT Regional Conformity Analysis - & Tri-Cities 2035 LRTP and FY 12-15 TIP 93.126 & 93.127 - Certain types of projects (such as safety projects, transit projects, and intersection improvements) that do not have adverse emission impacts are eempt from being included in the regional emissions analysis and will not be stopped in the absence of conforming LRTP or TIP: o All projects that are eempt under the federal conformity rule and would not typically be included in the regional network model were not included in the regional emissions analysis. Table ES-2 summarizes the emissions test results for the maintenance area for the 8-hour ozone standard for each year modeled. For this area, the projected emissions for nitrogen oides (NO ) and volatile organic compounds (VOC), both precursors to ozone formation, are less than budgets established in the maintenance plan for all years tested. The emission tests therefore are passed as required in the federal and state conformity rules. te, for transparency and to demonstrate consistency with the methodology applied in the maintenance plan, Table ES-2 presents separate emission totals for network and off-network emissions within the maintenance area. Network emissions include all regionally significant roadway and transit projects planned and/or programmed for opening within the timeframe of the plan that were included in the travel demand modeling for the conformity assessment for each year modeled. Off-network emissions are similar but account for travel on local and collector streets not included in the network model and therefore estimated separately. The regional total emissions presented for each year modeled include the contributions from each of these categories. Finally, for reference, Chapter 1 provides a review of applicable federal, state and local regulatory requirements, including those relating to the air quality maintenance plan.

DRAFT Regional Conformity Analysis - & Tri-Cities 2035 LRTP and FY 12-15 TIP This assessment complies with applicable federal and state requirements for transportation conformity, which include the final rule for transportation conformity published in the vember 24, 1993 Federal Register as well as subsequent amendments introduced by EPA and the U.S. DOT. Several sections of the amended rule have also been modified and/or remanded due to court rulings. Amendments to the conformity rule include those made on August 7 and vember 14, 1995, August 15, 1997 as well more recent amendments including the July 1, 2004 final conformity rule (69 FR 40004) that addresses conformity for the new ozone and PM 2.5 air quality standards and the March 1999 court decision, the May 6, 2005 final conformity rule (70 FR 31354) that addresses PM 2.5 precursors, the March 10, 2006 final conformity rule (71 FR 12468) that addresses PM 2.5 and PM 10 hot-spot analyses, and the January 24, 2008 final conformity rule (73 FR 4420) that addresses the provisions contained in SAFETEA-LU. On March 24, 2010 an update to the transportation conformity regulations was issued by EPA promulgating revisions to the transportation conformity rule to address the 2006 24-hour PM2.5 NAAQS, revocation of the annual PM10 NAAQS, and a court remand concerning hot-spot analyses in PM2.5, PM10 and CO areas. On March 14, 2012 EPA published the transportation conformity rule restructuring amendments (77 FR 14979). The amendments restructure sections 40 CFR 93.109 and 40 CFR 93.119 so that the eisting rule requirements apply to areas under any future new or revised NAAQS. The assessment also complies with additional federal guidance published jointly by the EPA and the U.S. DOT dated February 2006, by EPA on May 14, 1999, and by FHWA and FTA on June 14, 1999. --- Draft Report, May 2012 viii

DRAFT Regional Conformity Analysis & Tri-Cities 2035 LRTP and FY 12-15 TIP Chapter 1: Introduction and Overview This report documents the procedures and results of the transportation conformity analysis in the, Virginia 8-hour ozone maintenance area for the Metropolitan Planning Organization (MPO) and the Tri-Cities MPO FY 2012-2015 TIP and 2035 LRTP. The and Tri-Cities Metropolitan Planning Organizations serve as the forum for cooperative transportation decision-making for the area and, in this capacity, lead the development of the LRTP and TIP, in consultation and coordination with the Virginia Department of Transportation (VDOT) and other public and private stakeholders, as appropriate. The Regional Planning District Commission (RRPDC) and Crater Planning District Commission (CPDC) serve as staff for the and Tri-Cities MPO, respectively. VDOT, working with the MPO s and in consultation and coordination with other agencies and public and private stakeholders, as appropriate, leads the development of the requisite conformity analyses. The report is organized as follows: Chapter 1 (this chapter) provides an overview of applicable federal, state and local regulatory requirements and guidance, focusing on transportation conformity but also including a brief review of local air quality designations and related air quality plan development. Chapter 2 provides a detailed review of the modeling methodology and assumptions as applied in the conformity analysis. Chapter 3 summarizes the consultation process and results, which begins before the conformity (technical) analysis is initiated with inter-agency review of the methods, assumptions, schedule and project lists to be analyzed and concludes with MPO approval of the draft conformity analysis and subsequent review and approval by the US DOT in consultation with the US EPA. Chapter 4 documents the results of the conformity analysis, supporting a recommendation for a finding of conformity for the 2035 LRTP and FY 12-15 TIP. Transportation Conformity Federal, state and local requirements addressing transportation conformity apply for specified air quality nonattainment and maintenance areas in the Commonwealth of Virginia. These requirements originate from Section 176(c) of the Clean Air Act (CAA) as amended, which requires that federal agencies and MPOs not approve any transportation project, program, or plan that does not conform with an approved State Implementation Plan (SIP) for air quality. On vember 24, 1993, in keeping with CAA requirements, the U.S. Environmental Protection Agency (EPA) promulgated a rule (40 CFR Part 51, Subpart T) establishing "criteria and procedures for determining conformity to state and federal implementation plans of transportation plans, programs, and projects funded or approved under Title 23 U.S.C. or the Federal Transit Act." The final rule for transportation conformity became effective on December 27, 1993. EPA and the U.S. DOT have subsequently finalized a number of amendments to the federal conformity rule. Several sections of the amended rule have also been Draft Report, May 2012 1-1

DRAFT Regional Conformity Analysis - & Tri-Cities 2035 LRTP and FY 12-15 TIP modified and/or remanded due to court rulings. This conformity analysis meets the requirements of the conformity rule as amended to date by such actions. This includes amendments made on August 7 and vember 14, 1995, August 15, 1997 as well as more recent amendments including the July 1, 2004 final conformity rule (69 FR 40004) that addresses conformity for the new ozone and PM2.5 air quality standards and the March 1999 court decision, the May 6, 2005 final conformity rule (70 FR 31354) that addresses PM2.5 precursors, the March 10, 2006 final conformity rule (71 FR 12468) that addresses PM2.5 and PM10 hot-spot analyses, and the January 24, 2008 final conformity rule (73 FR 4420) that addresses the provisions contained in SAFETEA-LU. On March 24, 2010 an update to the transportation conformity regulations was issued by EPA promulgating revisions to the transportation conformity rule to address the 2006 24-hour PM2.5 NAAQS, revocation of the annual PM10 NAAQS, and a court remand concerning hot-spot analyses in PM2.5, PM10 and CO areas. On March 14, 2012 EPA published the transportation conformity rule restructuring amendments (77 FR 14979). The amendments restructure sections 40 CFR 93.109 and 40 CFR 93.119 so that the eisting rule requirements apply to areas under any future new or revised NAAQS. The assessment also complies with additional federal guidance published jointly by the EPA and the US Department of Transportation (USDOT) dated February 2006, by EPA on May 14, 1999, and by FHWA and FTA on June 14, 1999. The federal transportation conformity rule ensures conformity to a SIP's purpose of: (1) eliminating or reducing the number and severity of violations of national ambient air quality standards (NAAQS) and (2) attaining these standards. It also ensures that neither a transportation system as a whole nor an individual project will cause or contribute to new air quality violations or will increase the frequency or severity of eisting violations. Under the federal conformity rule, MPOs, state departments of transportation and the FHWA along with the FTA are responsible for conformity determinations for: (1) LRTPs, (2) TIPs, (3) transportation projects that receive federal funding or require FHWA or FTA approval, and (4) regionally significant non-federal projects, if these actions occur in areas that have been designated by EPA as nonattainment or maintenance areas for any of the criteria pollutants. The assessment also complies with the corresponding state conformity regulations specified at 9 VAC 5-151, also known as the Conformity SIP. The Conformity SIP was approved by EPA and published in the Federal Register on vember 20, 2009. See 73 FR 223 effective January 19, 2010. Transportation Conformity Rule Criteria Section 93.109 of the federal transportation conformity rule lists specific criteria required for conformity demonstrations for transportation plans, programs and projects. An ecerpt showing the criteria specific to plans and programs is provided below. The criteria and how each are met in this conformity analysis are reviewed in Chapter 4. A brief summary of each of the criteria is provided below: Draft Report, May 2012 1-2

DRAFT Regional Conformity Analysis - & Tri-Cities 2035 LRTP and FY 12-15 TIP 93.110 requires that conformity determinations be based upon the latest planning assumptions in force at the time of the determination. 93.111 requires that the latest emissions model available be used for the conformity analysis.

These procedures include: (1) providing reasonable opportunity for consultation with state air agencies, local air quality and transportation agencies, DOT, and EPA ( 93.105(a)(2)), and (2) establishing a proactive public involvement process that provides an opportunity for public review and comment prior to taking formal action on a conformity determination ( 93.105(e)). Consultation requirements are reviewed in more detail in Chapter 3. 93.113 details the steps necessary to demonstrate that the LRTP provides for the timely implementation of transportation control measures (TCMs) and is not interfering with their implementation. 93.118 requires the LRTP and TIP be consistent with the motor vehicle emission budget in the applicable SIP. Since emission budgets have been established for the area, as reviewed later in this chapter, the emission budget tests are applicable (and the Section 93.119 interim tests are not required.) For reference, section 93.118(b)(1)(ii) indicates that Emissions in years for which no motor vehicle emission budget(s) are specifically established must be less than or equal to the motor vehicle emissions budget(s) established for the most recent prior year. Additional requirements include or provide: 93.122 addresses procedures for determining regional transportation-related emissions. It requires that all regionally significant projects included in the LRTP or TIP be included in the regional emissions analysis, and includes specific requirements for the conduct of both transportation and emission modeling. The applicable modeling requirements of this section are summarized with the Draft Report, May 2012 1-3

DRAFT Regional Conformity Analysis - & Tri-Cities 2035 LRTP and FY 12-15 TIP conformity demonstration in Chapter 4. 93.126 & 93.127 allow certain types of projects (such as safety projects) that do not have adverse emissions impacts to be eempt from being included in the regional emissions analysis. For reference, the federal rule also specifies related requirements apply for projectlevel determinations: 93.114 requires a currently conforming plan and TIP at the time of project approval. 93.115 requires projects to be from a conforming transportation plan and program. Requirements for consultation are detailed in 93.105 of the federal transportation conformity rule and the Virginia Regulation for Transportation Conformity (9 VAC 5-151) also known as the conformity SIP. The Conformity SIP was approved by EPA and published in the Federal Register on vember 20, 2009. See 73 FR 223 effective January 19, 2010. Consultation requirements and processes are reviewed in detail in Chapter 3. Air Quality Designation Status for The area is currently in attainment for all of the NAAQS, which are summarized in Table 1-2. However, as the area has previously been designated as nonattainment for ozone and since been redesignated to attainment, it is subject to a maintenance plan and as such is subject to transportation conformity requirements. te emission budgets, presented later in this chapter, are established for the primary precursors to ozone, namely nitrogen oides (NO ) and volatile organic compounds (VOC). On vember 6, 1991, the, Virginia region was classified by EPA as a moderate ozone non-attainment area for the one-hour ozone standard (56 FR 56694). The designated non-attainment area included the town of Ashland, Charles City County (partial), Chesterfield County, City of Colonial Heights, Hanover County, Henrico County, City of Hopewell, and the City of. On vember 17, 1997, EPA approved Virginia s request for redesignation of the moderate 1-hour ozone nonattainment area from nonattainment to attainment and approved the area s maintenance plan. This redesignation was based upon three years of quality-assured ambient air monitoring data for the area, which demonstrated that the NAAQS for ozone had been attained. On July 18, 1997, EPA promulgated a revised (8-hour) ozone NAAQS of 0.08 parts per million (ppm). Designation of areas across the nation as attainment or nonattainment for the new standard was to be conducted at a later point by EPA. Draft Report, May 2012 1-4

DRAFT Regional Conformity Analysis - & Tri-Cities 2035 LRTP and FY 12-15 TIP On April 30, 2004, the EPA published a final rule designating as a moderate nonattainment area for ozone, effective June 15, 2004. This reclassification occurred as a result of the EPA promulgating the new 8-hour ozone standard (62 FR 38856). In addition to the jurisdictions included under the 1-hour ozone maintenance SIP (the town of Ashland, Charles City County (partial), Chesterfield County, City of Colonial Heights, Hanover County, Henrico County, City of Hopewell and City of ), the newly designated 8-hour ozone nonattainment area included three more jurisdictions: Charles City County (in entirety), the City of Petersburg and Prince George County. On vember 22, 2004, following a petition from the Commonwealth of Virginia, the EPA reclassified the area as a marginal nonattainment area for the 8-hour ozone standard (69 FR 23951). In October 2006, VDEQ submitted a redesignation request to EPA that included a maintenance plan and new motor vehicle emission budgets. EPA approved the redesignation request, and the area was redesignated into attainment with the 8-hour ozone standard, effective June 18, 2007. EPA also approved the associated maintenance plan, including the motor vehicle emission budgets and base year inventory (72 FR 30485) 4. Table 1-3 below presents the motor vehicle emission budgets, ecerpted from the final rule (72 FR 30485). te, while the table lists units of tons per day, the methodology presented in the Technical Support Document for the maintenance plan indicates the day selected to represent an average ozone season weekday. Also, for compliance with the federal conformity rule (Section 93.122, procedures for determining regional emissions), modeling for conformity analyses to meet the budgets specified in the maintenance plan would need to be consistent with certain key inputs, such as temperature profiles, as applied in the emission factor modeling for the maintenance plan. The modeling methodology and inputs for this conformity analysis are presented in the net chapter.

DRAFT Regional Conformity Analysis - & Tri-Cities 2035 LRTP and FY 12-15 TIP For reference, the maintenance area for the 8-hour ozone standard as specified in the maintenance plan is presented in Figure 1-1. The area includes the counties of Charles City, Chesterfield, Hanover, Henrico, Prince George, the cities of Colonial Heights, Hopewell, Petersburg and, and the town of Ashland. On June 8, 2007, the DC Circuit Court of Appeals denied the petitions relating to the December 22, 2006 ruling. The Court however granted the joint request of EPA and (other) environmental petitioners and clarified the December 22, 2006 ruling regarding conformity determinations 5 and the scope of the vacatur of the 2004 Final Rule 6. With the clarifications provided by the Court, and effective June 18, 2007, the budgets as presented in Table 1-3 above from the Final Rule (72 FR 30485) supersede the previous budgets established for the area for the one-hour ozone standard. On March 12, 2008 the EPA lowered the 8-hour ozone standard from 0.08 to 0.075 ppm, which had an effective date of May 27, 2008 (see 73 FR 16436). In May 2008, states, environmental groups and industry groups filed petitions with the D.C. Circuit Court of Appeals for review of the 2008 ozone standards. In March 2009, the court granted EPA s request to stay the litigation so the new administration could review the standards and determine whether they should be reconsidered. On January 6, 2010, EPA proposed to strengthen the NAAQS for ground-level ozone. EPA was proposing to strengthen the 8-hour primary ozone standard, designed to protect public health, to a level within the range of 0.060-0.070 parts per million (ppm). EPA was also proposing to establish a distinct cumulative, seasonal secondary standard, designed to protect sensitive vegetation and ecosystems, including forests, parks, wildlife refuges and wilderness areas. Following a public hearing and comment period EPA was planning to issue final standards by August 31, 2010. On September 2, 2011 EPA withdrew its reconsideration of the 2008 ozone standard and instead began moving forward on implementation of the 2008 ozone standard. On February 14, 2012, EPA proposed a rule (77 FR 8197: Implementing the 2008 National Ambient Air Quality Standards for Ozone: Proposed nattainment Area Classifications Approach and Attainment Deadlines.) that would take a necessary step to implement the 2008 NAAQS for ground-level ozone. Under this rule EPA is also proposing to revoke the 1997 ozone standards one year after designations for the 2008 standards are effective for purposes of transportation conformity. 5 On conformity, the ruling stated: We grant the joint request by EPA and the Environmental Petitioners to make eplicit that the court s reference to conformity determinations speaks only to the use of one-hour motor vehicle emissions budgets as part of 8-hour conformity determinations until 8-hour motor vehicle emissions budgets are available. (Section III, paragraph 1, page 7). 6 On vacatur of the 2004 Final Rule, the ruling stated: We also grant their request that the 2004 Rule be vacated only to the etent that the court has sustained challenges to it. EPA is urged to act promptly in promulgating a revised rule that effectuates the statutory mandate by implementing the 8-hour standard, (Section III, paragraph 2, pp.7-8). Draft Report, May 2012 1-7

DRAFT Regional Conformity Analysis & Tri-Cities 2035 LRTP and FY 12-15 TIP Chapter 2: Modeling Methodology and Assumptions This chapter presents an overview of the modeling approach including key input data and assumptions as applied for the regional conformity analysis for the 2035 LRTP and FY 12-15 TIP for the 8-hour ozone maintenance area. General Emission Calculation Methodology Emission forecasts for the maintenance area were developed using a traditional four-step transportation planning model, the EPA approved emission factor model (MOBILE6.2), and a post-processor developed by VDOT to combine the modeled and non-modeled VMT and emission factors to generate emission forecasts. On March 2, 2010, EPA officially released the net generation Motor Vehicle Emission Simulator (MOVES) model for use in SIP development and regional conformity applications. The EPA notice indicated that a two-year grace period (ending March 2, 2012) applies for use of the new model in regional emissions analyses for transportation conformity determinations. On February 27, 2012 the two-year grace period was etended an additional year ending March 2, 2013. Therefore, for regional conformity analyses initiated before or within the threeyear grace period, the MOBILE6.2 model (the model previously designated as the official model by EPA) may continue to be applied. Figure 2-1 below summarizes the key steps in the development of regional emission forecasts for the conformity analysis. The process begins with development of forecasts for traffic volumes on the regional transportation network, for which key inputs include the latest available socioeconomic forecasts (including population and employment) and LRTP and TIP project lists. Traffic forecast volumes for the horizon year (2035) of the LRTP were developed with a standard four-step model developed and maintained by VDOT and the model was recently moved into the CUBE scripting language. The Tri Cities and MPO staffs are responsible for running the travel demand model for conformity purposes. Changes to the model are discussed later in this document. The travel model networks include all functionally classified roadways: interstates, freeways, epressways, principal arterials, minor arterials, and collector streets. In addition a small number of local streets necessary to maintain roadway network connectivity are also coded. For each conformity analysis year (, 2018, 2028 and 2035), estimates of socio-economic growth were prepared, significant highway and transit projects were coded, and model runs were performed. The networks are developed for conformity analysis years selected to meet the requirements of the transportation conformity rule, and must include years for which regional emission budgets are specified in the applicable maintenance plan, as well as the last year of the LRTP. Concurrently, forecasts for emission factors are developed using the EPA-approved emission factor model (currently MOBILE6.2) for each forecast year. For each year, emission factors are generated (in units of grams of pollutant emitted per vehicle mile traveled) for each pollutant to be modeled, roadway class or facility type, and jurisdiction for speeds ranging from 2.5 to 65 miles per hour. Draft Report, May 2012 2-1

DRAFT Regional Conformity Analysis - & Tri-Cities 2035 LRTP and FY 12-15 TIP The output from the travel demand model and the emission factor model serve as inputs to a post-processor that is then applied to calculate regional total emissions. The forecast VMT for each year (by link including jurisdiction, vehicle class, facility type and speed) is combined in the post-processor with the forecast emission factors for each pollutant (by facility type and speed) to generate forecast emissions for each pollutant for each network link in each jurisdiction for each analysis year. Emissions for traffic operating on off-network facilities (collectors and local streets) are too small to be included in the regional transportation model networks and are estimated separately. The post-processor is applied to develop estimates of VMT for these facilities by etrapolating current traffic counts based on socioeconomic forecasts. Emission factors are applied to the projections for local and collector VMT to generate forecasts for off-network emissions by jurisdiction for each analysis year. The network and off-network emissions are then totaled to arrive at forecasts for regional total emissions for the maintenance area for each analysis year. Emission tests as described in the previous chapter are then applied to demonstrate regional transportation conformity.

DRAFT Regional Conformity Analysis - & Tri-Cities 2035 LRTP and FY 12-15 TIP The selection of analysis years and associated emission tests is presented first. The models and processors used in the analysis are reviewed, with a discussion of methodology as well as key inputs and assumptions for the modeling. The modeling discussion addresses transportation demand forecasts first, then the development of forecasts for emission factors. The modeling results for this conformity analysis are presented in Chapter 4. Analysis Years and Budgets Table 2-1 presents the motor vehicle emission budgets as specified in the maintenance plan (reviewed in the previous chapter) as well as the years selected for modeling for this conformity analysis. Previously applicable budgets established for the one-hour standard are superseded by these budgets. Table 2-1: Analysis Years and Budgets Year Regional Emission Budgets (tons per ozone season weekday) NO VOC 2018 * 26.827 23.845 2028 26.827 23.845 2035 26.827 23.845 * Budgets specified in 72 FR 30485, effective June 18, 2007. The years selected for analysis are consistent with the requirements of Section 93.118 of the conformity rule. The maintenance plan specifies budgets for 2018, and years for which budgets are established are required in the conformity rule to be analyzed. Additionally, the conformity rule requires modeling for the last year of the transportation plan (2035), and that years modeled be no more than ten years apart. To meet the latter requirement, the year 2028 was selected. te section 93.118 the conformity rule requires budgets established for the most recent prior year to apply for years for which budgets have not been specifically established. For this analysis, the 2018 budgets as listed above are applicable for the years 2028 and 2035 as well. Draft Report, May 2012 2-3

DRAFT Regional Conformity Analysis - & Tri-Cities 2035 LRTP and FY 12-15 TIP Transportation Demand Forecasting - CUBE Model The CUBE modeling platform consists of a library of scriptable programs that facilitate construction of travel demand forecasting models. Using that modeling platform, technical staff at VDOT has developed and maintain a regional travel demand model for the and Tri-Cities MPO study areas. The model is a four-step travel demand model that includes trip generation, trip distribution, mode choice and traffic assignment. The model includes feedback between highway assignment and trip distribution. The coverage area of the model as shown in Figure 1-1 includes the 8-hour ozone maintenance area as well as New Kent County and parts of Goochland, Powhatan, and Dinwiddie counties. The CUBE model was validated against 2008 traffic volumes, land use, demographics, and other socio-economic factors. The validated model was then used to develop future year traffic models and volume estimates. Highway and transit system data are coded by the model developers to create a representation of the regional transportation network. Attributes coded into the network include highway features such as road segment length, capacity, number of lanes, and free-flow speed, and transit operating characteristics such as fares, bus stops, and hours and frequency of service. The networks include all available motorized modes of travel, including single-occupant automobiles, multiple-occupant ( high occupancy ) automobiles, park-and-ride epress bus service, and standard bus service. Based on the coded network, travel time and cost data are tabulated for use in subsequent model steps. Trip making activity is estimated during the trip generation and trip distribution steps. Trip generation uses summary information from each traffic analysis zone (TAZ) to compute the number of trips produced in and attracted to each TAZ. The summary information includes number of households, total population, group-quarters population, retail and non-retail employment, and number of automobiles available to households. These socio-economic data are prepared by each of the MPO s and compiled for use in the model. Trips are generated by purpose (home based work, home based shop, home based social/recreational, home based other and nonhome based work and non-home based other). Commercial vehicle activity is separated as different trip purpose. Trips that start or end outside the region, as well as trips that simply pass through the region, are treated as separate trip purposes as well. These eternal trips were estimated from traffic counts observed at major eit stations in the year 2008 and then epanded for future years using growth trend estimates of traffic at the eternal stations. The trip distribution step joins the production and attraction end of each trip using factors designed to reproduce observed traffic volumes and trip times in the base year. The trip distribution step uses a standard gravity model, with different factors for each trip purpose. Both the previous TP+ model and the new CUBE model were designed to use feedback from the highway assignment into trip distribution to better approimate observed traffic conditions (and, in the future years, to better estimate the differential effects of additional trips and transportation facilities). The feedback takes into account the effect of congestion on route choice, since the most commonly chosen route to a destination will depend on whether or not a particular route is congested or free-flowing, and the level of congestion in turn depends on what route travelers are most inclined to choose. Draft Report, May 2012 2-4

DRAFT Regional Conformity Analysis - & Tri-Cities 2035 LRTP and FY 12-15 TIP Trip tables from trip distribution, along with network-based travel time and cost data, are input to the mode split step to estimate trip tables by trip purpose, travel period (peak or off-peak) and mode. The mode split step uses a nested logit model to allocate trips between automobile, regular bus and epress bus, based on differences in time and cost among the modes. Auto-occupancy rates that vary by trip purpose are applied to automobile trips, and the trip tables are assembled for assignment to the highway and transit networks. During the highway assignment step, trips between each zone pair are loaded onto the highway network and balanced with congestion effects. Highway assignment uses a capacity restraint formula that limits how many trips can be assigned to each roadway link based on its practical capacity. During assignment, routes are assembled between each zone pair based on the shortest routes under congested conditions. A feedback loop is included to ensure that speeds from the resulting highway assignments are fed back through the forecasting process. In transit assignment, trips are assigned to the most efficient transit route available, taking into account waiting time, travel time, transfers required, and fare. Transit assignment is based on the best route, and does not have a capacity restraint or congestion balancing component. The output of the highway assignment process is a network file that includes forecast traffic volumes on each roadway segment, as well as an estimate of congested travel speed. That file is referred to as a loaded network. This overall modeling process is applied for each analysis year. Key inputs to the network model are reviewed below. Socioeconomic Forecasts The RRPDC and CPDC provided the socioeconomic data to be used in the transportation model. The RRPDC, CPDC, and the member governments in the counties of Charles City, Chesterfield, Hanover, Henrico and Prince George as well as the cities of Colonial Heights,, Hopewell and Petersburg developed a distribution of the regional population and employment projections to TAZs used in the transportation model. The counties of Goochland, Powhatan, New Kent and Dinwiddie are not part of the 8-hour ozone maintenance area, but provided socioeconomic data, as they are part of the modeled region. To estimate population, employment, Households and number of autos, documentation from the 2008 US Census, Virginia Division of Motor Vehicles (DMV) as well as the Virginia Employment Commission (VEC) was collected. Projections for 2035 were estimated starting with the compilation of 2008 figures in the and Tri-Cities MPO areas, and then a regionally collaborated estimate of figures for 2035 was developed. The forecasted numbers were prepared under the guidance of the member governments and approved by the respective MPOs. Table 2-2 presents the socioeconomic forecast totals for the jurisdictions that lie within the 8-hour ozone maintenance area. The forecasts (including interim years and sub-allocations as appropriate) represent the latest projections available and Draft Report, May 2012 2-5

Project Lists & Regional Network Development A project list was generated to develop the transportation networks by analysis year, and to identify projects that are regionally significant (or otherwise subject to transportation conformity analysis). Projects subject to conformity that could not be modeled in the Travel Demand Forecast Model were analyzed off-model. All projects occurring on roadway segments bearing a Federal Functional Classification were coded, provided that the nature of the project was amenable to network coding. In general, changes were coded for new facilities, road widenings that increase the number of through travel lanes, interchanges on limited access facilities, and alterations to the road s operating characteristics (such as speed limit and presence of traffic signals). Turn lanes and at-grade intersection improvements were not included in the modeled network; as such improvements are not amenable to modeling at a regional scale. This conformity analysis is based on the region s 2035 LRTP and FY 12-15 TIP. Consistent with the requirements of the Rule, regional emission analyses were performed for 2018, 2028 and 2035 for the TIP and LRTP. The CUBE transportation networks for each of the four analysis years include all regionally significant modeled projects included in the LRTP and TIP, and coded into the appropriate year based on anticipated construction completion dates. Where possible, completion dates reflect estimates included in the LRTP/TIP project descriptions or in VDOT s si-year plan. For projects without completion date estimates, they were determined by adding three years to the anticipated project advertisement date. The modeled network for each analysis year reflects the travel conditions epected to be in place during that analysis year. For eample, the 2018 network includes eisting roadways as well as projects listed in the 2035 LRTP and FY 12-15 TIP that are anticipated to be open to traffic by 2018. Subsequent networks include eisting networks plus completed projects from earlier analysis years. Thus, the 2028 network includes all the 2018 projects plus additional projects completed by 2028.

DRAFT Regional Conformity Analysis - & Tri-Cities 2035 LRTP and FY 12-15 TIP Appendi E presents the final project lists used to develop the LRTP and TIP networks for each analysis year, including the first analysis year for all regionally significant projects. Travel Demand Forecast Model Output The CUBE travel demand model generates estimates of VMT for all major roadway classes (minor arterial and above). Collector and local roadway VMT are estimated through off-model procedures. The final assigned volumes from the CUBE transportation model are etracted from the loaded network that is computed during the highway assignment step. Vehicle miles traveled are computed within the model by multiplying the volume estimated for each network link by the length of the link. The post processor uses the loaded network volumes and capacities, along with other relevant travel information such as number of lanes, free flow speed, and link length to calculate congested speeds for each of the highway functional classes. Appendi B contains VMT estimates by jurisdiction, roadway class, and time of day for each analysis year. The roadway capacity per lane, which is used for capacity restraint in the travel demand model, is etracted from the model network, and is used along with traffic volumes and number of lanes to compute congested roadway speeds in the postprocessor. Other Off-line Analyses Some transportation projects that have a potentially significant impact on regional air quality cannot be coded into the transportation modeling network. These are categorized as off-line projects and are analyzed using a variety of methodologies that include elasticity/pivot-point analysis and the use of traffic engineering principles to estimate their traffic and emission impacts. Off-line analyses for can also include transit bus replacements, Congestion Mitigation and Air Quality (CMAQ) funded projects, van pools, and parkand-ride lots. Since these adjustments were not needed to demonstrate conformity for this update of the 2035 LRTP and FY 12-15 TIP, they were not applied. Draft Report, May 2012 2-7

DRAFT Regional Conformity Analysis - & Tri-Cities 2035 LRTP and FY 12-15 TIP Emission Factor Forecasting (US EPA MOBILE6.2 Model) The federal conformity rule at 93.111(a) requires the use of the latest emission model as follows: The conformity determination must be based on the latest emission estimation model available. 7 However, when EPA issues a new model, a grace or transition period applies in which the previous version of the model may still be applied, per the federal conformity rule at 93.111(c) which states: Transportation plan and TIP conformity analyses for which the emissions analysis was begun during the grace period or before the Federal Register notice of availability of the latest emission model may continue to use the previous version of the model. On March 2, 2010, EPA officially released the net generation Motor Vehicle Emission Simulator (MOVES) model for use in SIP development and regional conformity applications 8. The EPA notice indicated that a two-year grace period (ending March 2, 2012) applies for use of the new model in regional emissions analyses for transportation conformity determinations. On February 27, 2012 the two-year grace period was etended an additional year ending March 2, 2013. Therefore, for regional conformity analyses initiated before or within the three-year grace period, the MOBILE6.2 model (the model previously designated as the official model by EPA) may continue to be applied. The MOBILE6.2 model was designed to be used to develop estimates of historic, current and future emission factors for area-wide (e.g., regional) on-road motor vehicle fleets. MOBILE6.2 can calculate in-use fleet average emission factors for: Criteria pollutants: hydrocarbons, carbon monoide, nitrogen oides, ehaust particulate, hazardous air pollutants (HAP), and carbon dioide. Gas, diesel, and natural gas-fueled cars, trucks, buses and motorcycles. Calendar years between 1952 and 2050. Emission factors are generated by the model in units of grams of pollutant per vehicle mile of travel. As noted previously, emission factors are combined with VMT projections obtained from the regional travel demand model to generate estimates of regional emissions. Modeled emission factors vary with vehicle class, age (registration distribution by vehicle class), humidity, ambient temperatures, fuel specifications, and operation (speed, by roadway functional class). For this analysis, both national default data and region-specific inputs were used with MOBILE6.2 to determine emission factors for this analysis.

DRAFT Regional Conformity Analysis - & Tri-Cities 2035 LRTP and FY 12-15 TIP 9 analysis. From the regulatory announcement : New Standards for Heavy-Duty Highway Engines and Vehicles [EPA is] finalizing a PM emissions standard for new heavy-duty engines of 0.01 grams per brake-horsepower-hour (g/bhp-hr), to take full effect for diesels in the 2007 model year. [EPA is] also finalizing standards for NO and non-methane hydrocarbons (NMHC) of 0.20 g/bhp-hr and 0.14 g/bhp-hr, respectively. These NO and NMHC standards will be phased in together between 2007 and 2010, for diesel engines. The phase-in will be on a percent of-sales basis: 50 percent from 2007 to 2009 and 100 percent in 2010. Gasoline engines will be subject to these standards based on a phase in requiring 50 percent compliance in the 2008 model year and 100 percent compliance in the 2009 model year. The program includes fleibility provisions to facilitate the transition to the new standards and to encourage the early introduction of clean technologies, and adjustments to various testing and compliance requirements to address differences between the new technologies and eisting engine based technologies. New Standards for Diesel Fuel Refiners will be required to start producing diesel fuel for use in highway vehicles with a sulfur content of no more than 15 parts per million (ppm), beginning June 1, 2006. At the terminal level, highway diesel fuel sold as low sulfur fuel will be required to meet the 15 ppm sulfur standard as of July 15, 2006. For retail stations and fleets, highway diesel fuel sold as low sulfur fuel must meet the 15 ppm sulfur standard by September 1, 2006. This program includes a combination of fleibilities available to refiners to ensure a smooth transition to low sulfur highway diesel fuel. National Low Emission Vehicle (NLEV) Program: The NLEV program was specified in the emission factor modeling for the conformity analysis. The NLEV program, finalized by EPA in March 1998, implemented cleaner lightduty gasoline vehicles beginning in model year 1999. Tier 2 Vehicle Emission Standards: EPA Tier 2 vehicle emission standards implementation beginning with the 2004 model year was specified for the modeling for the conformity analysis.

For commercial gasoline, the program will o Significantly reduce average gasoline sulfur levels nationwide as early as 2000, fully phased in in 2006. Refiners will generally add refining equipment to remove sulfur in their refining processes. Importers of gasoline will be required to import and market only gasoline meeting the sulfur limits. o Enable the new Tier 2 vehicles to meet the emission standards by greatly reducing the degradation of vehicle emission control performance from sulfur in gasoline. Lower sulfur gasoline also appears to be necessary for the introduction of advanced technologies that promise higher fuel economy but are very susceptible to sulfur poisoning (for eample, gasoline direct injection engines). o Reduce emissions from NLEV vehicles and other vehicles already on the road.

DRAFT Regional Conformity Analysis & Tri-Cities 2035 LRTP and FY 12-15 TIP Post-Processing An overview of the general approach applied in the analysis for calculating regional total emissions from on-road motor vehicles emission was provided at the beginning of this chapter. This section summarizes specific adjustments made in the postprocessor to the travel demand forecasts to improve the emission forecasts. The post-processor first adjusts travel demand forecasts and related parameters as needed for the emission calculations, and then generates the emission estimates using the forecast VMT by roadway type and jurisdiction with the emission factors that were generated using MOBILE6.2. The specific adjustments to the traffic forecasts are reviewed in turn below. The congested speeds calculated in the post-processor were developed using accepted transportation engineering methods based on the 2000 Highway Capacity Manual (HCM) and National Cooperative Highway Research Program (NCHRP) Report 387. Congested Speed Calculation The post-processor estimates congested speeds using standard Bureau of Public Roads (BPR) formulae that are based upon free flow speeds, volumes and capacity. Free flow speed is the speed at which a vehicle on the roadway segment would travel given no conflict with other traffic, i.e., no congestion. As traffic volumes increase and the carrying capacity of the roadway is reached (i.e. congestion increases), average speeds decrease. The free flow speeds used are consistent with those used in the CUBE model. The formulae originally developed by the BPR to describe the relationship between congested speeds and roadway free flow speeds, volumes and capacities are now applied in transportation models as standard practice. The post-processor uses two forms of the BPR equation. The first is for non-signalized roadway segments: speed for unsignalized corridor facilities = 1+ 0.2 free flow speed ( volume / capacity) 10 The second is for signalized roadway segments, defined as signalized facilities on which traffic signals are spaced two miles or less apart: speed for signalized facilities corridor free = 1+ 0.05 flow speed ( volume / capacity) 10 Emission factors calculated using MOBILE6.2 are imported into the post-processor and applied with the VMT and speed data for both network and off-network facilities to generate estimates of emissions by jurisdiction and facility type for the maintenance area.

DRAFT Regional Conformity Analysis - & Tri-Cities 2035 LRTP and FY 12-15 TIP Traffic Adjustment Factors The vehicle activity estimates were forecast through the CUBE model, and are reported as Vehicle Miles Traveled (VMT). As noted above, the roadway network representing the transportation conditions for each analysis year forms the basis for the estimation of highway volumes. The model produces VMT estimates that correspond to Average Annualized Daily Traffic (AADT). An ozone season weekday adjustment factor is applied to the modeled VMT on each roadway to estimate average daily summer traffic, consistent with the method used in the 8-hour ozone maintenance plan. Table 2-8 presents average weekday adjustment factors for the area. These are based upon HPMS data for 2008 as presented in "Traffic Trends and Characteristics for the 2008 Highway Emissions Inventory, " (VDOT, 2009). The tabulated factors were obtained as the average for the values reported for months of May through September for the area. The factors are presented by FHWA roadway functional class.

DRAFT Regional Conformity Analysis & Tri-Cities 2035 LRTP and FY 12-15 TIP Chapter 3: Consultation In addition to detailed requirements specified in the federal conformity rule for consultation on conformity analyses, related state and local requirements apply. Consultation conducted for conformity purposes is generally in addition to that conducted in the development of the LRTP and TIP (and their respective amendments or updates). This section documents applicable regulatory requirements for consultation related to conformity analyses and that conducted for this analysis to meet those requirements. Consultation Requirements and Processes Federal conformity rule requirements address both interagency and public consultation. Section 93.112 (Criteria and procedures: Consultation) requires that: Conformity must be determined according to the consultation procedures in this subpart and in the applicable implementation plan, and according to the public involvement procedures established in compliance with 23 CFR Part 450. Until the implementation plan revision required by 51.390 of this chapter is fully approved by EPA, the conformity determination must be made according to 93.105 (a)(2) and (e) and the requirements of 23 CFR Part 450. In response to the requirements of Section 51.390, the Virginia Regulation for Transportation Conformity (9 VAC 5-151) 12 was passed into state law in 2007. The Conformity SIP required by 51.390 was approved by EPA and published in the Federal Register on vember 20, 2009 (See 73 FR 223 with an effective date of January 19 th, 2010). The consultation requirements in the conformity SIP are generally consistent with the Federal Transportation Conformity Rule, although it also requires consultation with the Lead Planning Organization (LPO) established pursuant to Section 174 of the federal Clean Air Act as amended (CAA). The Metropolitan Air Quality Committee is the designated LPO for the region. Although not specifically listed in the current (2005) ICG procedures, but consistent with the new Virginia Regulation for Transportation Conformity, a representative of the designated Lead Planning Organization (LPO) for the region is also invited to participate in inter-agency consultation on conformity issues. Section 93.105(a)(2) requires that: Before EPA approves the conformity implementation plan revision required by 51.390 of this chapter, MPOs and State departments of transportation must provide reasonable opportunity for consultation with State air agencies, local air quality and transportation agencies, DOT and EPA, including consultation on the issues described in paragraph (c)(1) of this section, before making conformity determinations. The referenced Section 93.105(c)[(1)] requires that: Interagency consultation procedures shall also include the following specific process: (1) A process involving the MPO, State and local air quality planning agencies, State and local transportation agencies, EPA and DOT for the following: (i) Evaluating and choosing a model (or models) and associated methods and assumptions to be used in hot-spot analyses and regional emissions analyses; (ii) Determining which minor arterials and other transportation projects should be considered regionally significant for the purposes of regional emissions analysis 12 See http://leg1.state.va.us/000/reg/toc09005.htm#c0151.

Section 93.105(e) requires that: Public consultation procedures. Affected agencies making conformity determinations on transportation plans, programs, and projects shall establish a proactive public involvement process which provides opportunity for public review and comment by, at a minimum, providing reasonable public access to technical and policy information considered by the agency at the beginning of the public comment period and prior to taking formal action on a conformity determination for all transportation plans and TIPs, consistent with these requirements and those of 23 CFR450.316(b). Any charges imposed for public inspection and copying should be consistent with the fee schedule contained in 49 CFR 7.43. In addition, these agencies must specifically address in writing all public comments that known plans for a regionally significant project which is not receiving FHWA or FTA funding or approval have not been properly reflected in the emissions analysis supporting a proposed conformity finding for a transportation plan or TIP. These agencies shall also provide opportunity for public involvement in conformity determinations for projects where otherwise required by law. In response to the requirements of 93.105(c)(1) and (e) as stated above, on September 30, 2001 and October 29, 2001, respectively, the and Tri- Cities MPO s approved the Interagency Consultation Procedures for the 1-hour ozone maintenance area. On October 13, 2005, the and Tri-Cities MPO s approved revised Interagency Consultation Procedures to address the epanded 8-hour ozone maintenance area. These procedures were developed to meet the federal requirements for consultation as cited above, and included the formation of an Interagency Consultation Group (ICG) comprised of representatives of federal, state and local air and transportation agencies. Table 3-1 presents the current membership of the ICG. Overall, MPOs are the lead agencies when developing planning work programs, LRTPs, TIPs and any revisions to the preceding documents, and associated conformity determinations.

DRAFT Regional Conformity Analysis - & Tri-Cities 2035 LRTP and FY 12-15 TIP Chapter 4: Conformity Demonstration & Conclusion The results of the conformity analysis for the 2035 LRTP and FY 12-15 TIP are presented in this chapter. The analysis was conducted to meet all applicable federal, state, and local requirements, applying the methodology and key input data and assumptions as presented in the previous chapters. With conformity so demonstrated based on the criteria specified in the federal conformity rule, including emission tests for the LRTP and TIP as well as other criteria, a finding of conformity for the LRTP and TIP is supported. Conformity Demonstration Emission Tests for the 2035 LRTP and FY 12-15 TIP Table 4-1 presents the results of the emission (budget) tests required by Section 93.118 of the federal conformity rule. Emission budgets specified in the maintenance plan for the year 2018 were applied for this analysis. For all years tested, the forecasts (build) emissions for NO and VOC are less than the applicable budgets. The conformity budget tests are therefore satisfied for the 2035 LRTP and FY 12-15 TIP. Other Conformity Requirements Section 93.109 of the federal conformity rule, and in particular Table 1 - Conformity Criteria as presented in that section, list criteria for demonstrating conformity. Compliance with these criteria as well as a fiscal constraint requirement also specified in the federal conformity rule is documented below for the 2035 LRTP and FY 12-15 TIP, with applicable sections of the rule ecerpted for reference: 93.108 Fiscal Constraints for transportation plans and TIPs. Transportation Plans and TIPs must fiscally consistent with DOT s metropolitan planning regulations at 23 CFR Part 450 in order to be found in conformity. o The MPO documents fiscal constraint with the development of the LRTP and TIP, and includes specific sections or chapters addressing cost estimates and financial constraint. For the purposes of this conformity demonstration, therefore, fiscal constraint is indicated by MPO approval of the project lists for the LRTP and TIP and the documentation provided with those reports. Additionally, a recommendation for a finding of conformity is conditional upon any further and separate review as may be required by the US DOT for the fiscal constraint criterion consistent with Section 93.108 of the federal conformity rule as well as requirements of federal planning regulations specified at 23 CFR Part 450.

DRAFT Regional Conformity Analysis - & Tri-Cities 2035 LRTP and FY 12-15 TIP analysis. Regional roadway and transit networks were updated as appropriate using the Plan and Program project lists, which were subjected to interagency consultation as described below. Emission controls assumed for the analysis were consistent with those specified in the applicable implementation (maintenance) plan revision. All of the latest planning assumptions and other aspects of the conformity analysis were reviewed by the Interagency Consultation Group (ICG) at the beginning of the conformity analysis process, as documented in the chapter on consultation and in Appendi D. Additional details are provided below. o 93.110 (b) Socioeconomic Forecasts: This section requires that Assumptions must be derived from the estimates of current and future population, employment, travel, and congestion most recently developed by the MPO or other agency authorized to make such estimates and approved by the MPO. Further, Section 93.122(b)(1)(ii) requires that Land use, population, employment, and other network-based travel model assumptions must be documented and based on the best available information. Section 93.122(b)(1)(iii) adds that Scenarios of land development and use must be consistent with the future transportation system alternatives for which emissions are being estimated. As documented in the main report, the socioeconomic forecasts for 2035 (including interim years and sub-allocations as appropriate) represent the latest projections available and approved for use with the 2035 LRTP. o 93.110(c) and (d) Transit: These sections respectively require that The conformity determination for each transportation plan and TIP must discuss how transit operating policies (including fares and service levels) and assumed transit ridership have changed since the previous conformity determination and The conformity determination must include reasonable assumptions about transit service and increases in transit fares and road and bridge tolls over time. Transit operating policies (including fares and service levels) and modeling for transit (ridership) have not changed significantly since the previous conformity determination. Transit service is included in future networks for the region. While future transit ridership is effectively determined in the course of modeling for the conformity analysis, details on current transit operating policies including fares and service levels may be found on the Greater Transit Company (GRTC) and Petersburg Area Transit (PAT) websites 13. Transit service and fares as well as road tolls are also addressed in supporting documentation for the Plan and associated modeling. o 93.110(e) Transportation Control Measures (TCMs) and Other Measures: This section requires that The conformity determination must use the latest eisting information regarding the effectiveness of the TCMs [transportation control measures] and other implementation plan measures which have already been implemented. 13 See www.ridegrtc.org and http://www.petersburg-va.org/transit/patgrtc.htm, respectively.

DRAFT Regional Conformity Analysis - & Tri-Cities 2035 LRTP and FY 12-15 TIP The applicable SIP revision (maintenance plan) for the maintenance area does not include transportation control measures (TCMs). TCMs are therefore not required for the conformity analysis or determination. Accordingly, credit for TCMs was not taken in this analysis. See 72 FR 30490, effective June 18, 2007. 93.111 Criteria and procedures: Latest emissions model: o The latest EPA approved version of the emission (factor) model MOBILE6.2, was applied for this conformity analysis as allowed by a 2 year grace period while transitioning to the new MOVES model. 93.112 Criteria and procedures: Consultation. Until the implementation plan revision required by 51.390 of this chapter is fully approved by EPA, the conformity determination must be made according to 93.105 (a)(2) and (e) and the requirements of 23 CFR part 450. The Conformity SIP required by 51.390 was approved by EPA and published in the Federal Register on vember 20, 2009 (See 73 FR 223 with an effective date of January 19, 2010). The consultation requirements in the conformity SIP are generally consistent with the Federal Transportation Conformity Rule, although it also requires consultation with the Lead Planning Organization (LPO) established pursuant to Section 174 of the federal Clean Air Act as amended (CAA). The Metropolitan Air Quality Committee is the designated LPO for the region. Involvement of the VDEQ staff representative for that Committee in the local inter-agency consultation process for conformity is considered to fulfill that requirement. o The consultation procedures employed follow the requirements outlined in 93.105(a)(2) and (e), 9 VAC 5-151, and the requirements of 23 CFR part 450. The consultation conducted for this conformity analysis is documented in detail in Chapter 3 with meeting and related materials including minutes copied in Appendi D. That consultation is summarized below: o o As noted in Chapter 3, documentation of the consultation conducted including the ICG membership list, meeting agenda and presentation materials, schedule, handouts, and minutes is provided in Appendi D. An opportunity for public input was provided at the ICG meeting held at the beginning of the conformity analysis process at which the conformity methodology, schedule and project lists were presented. Project lists as finalized following consultation are presented in Appendi E. Further, the consultation conducted for this conformity analysis followed the and Tri-Cities MPO approved Interagency Consultation Group Procedures. 93.113 Criteria and procedures: Timely implementation of TCMs. The transportation plan, TIP must provide for the timely implementation of TCMs from the applicable implementation plan Paragraph (b) identifies specific requirements for plans, and paragraph (c) for TIPs. o TCMs were not included in the applicable implementation plan or revision for the maintenance area for the 8-hour ozone standard. The criteria may therefore be considered as not applicable or as satisfied without further action for this area. 93.118 - Criteria and procedures: Motor vehicle emissions budget. (a) The transportation plan, TIP must be consistent with the motor vehicle emissions budget(s) specified in the applicable implementation plan This Draft Report, May 2012 4-4

DRAFT Regional Conformity Analysis - & Tri-Cities 2035 LRTP and FY 12-15 TIP criterion is satisfied if it is demonstrated that emissions of the pollutants are less than or equal to the motor vehicle emissions budget(s) : (b) Consistency with the motor vehicle emissions budget(s) must be demonstrated for each year for which the applicable implementation plan specifically establishes motor vehicle emissions budget(s), for the attainment year (if it is within the timeframe of the transportation plan), for the last year of the transportation plan s forecast period, and for any intermediate years as necessary so that the years for which consistency is demonstrated are no more than ten years apart (c) Consistency with the motor vehicle emissions budget(s) must be demonstrated for each pollutant for which the area is in nonattainment or maintenance and for which the applicable implementation plan establishes a motor vehicle emissions budget. (d) Consistency with the motor vehicle emission budget(s) must be demonstrated by including emissions from the entire transportation system o o o o The applicable implementation plan is the maintenance plan for the 8-hour ozone standard approved and made effective by EPA as of June 18, 2007, which established motor vehicle emission budgets for VOC and NO for the years 2011 and 2018. As documented above, total VOC and NO emissions associated with the regional transportation system as planned and programmed in the 2035 LRTP and FY 12-15 TIP for all analysis years have been modeled and demonstrated to be consistent with (i.e., less than) the motor vehicle emission budgets established in the maintenance plan for those pollutants for all years modeled. The years selected for analysis are consistent with the requirements of this section of the conformity rule. The maintenance plan specifies budgets for 2011 and 2018, and years for which budgets are established are required to be analyzed. Additionally, the conformity rule requires modeling for the last year of the transportation plan (2035), and that years modeled be no more than ten years apart. To meet the latter requirement, the year 2028 was selected. The motor vehicle emissions budget criterion is therefore met. Applicable budgets and the selection of years for modeling are reviewed in Chapters 1 and 2. o Other related requirements that were not specifically included as criteria in Table 1 - Conformity Criteria (Section 93.109) are reviewed below: 93.122 Procedures for determining regional transportation-related emissions. All applicable requirements of this section were met, as documented in Chapter 2, including: (a) (1) all regionally significant projects included in the LRTP and TIP were included in the regional emissions analysis ; (6) ambient temperatures used in the conformity analysis are consistent with those used to establish the emission budget in the applicable implementation plan (and, similarly, relative humidity data and average barometric pressure as applied are consistent); and (7) reasonable methods were applied to estimate VMT on off-network roadways, Draft Report, May 2012 4-5

DRAFT Regional Conformity Analysis - & Tri-Cities 2035 LRTP and FY 12-15 TIP (b) (1) A regional network model was applied. Land use, population, employment and other assumptions were documented and based on the best available information. Assumed land use development is consistent with the future transportation system. A capacity sensitive assignment methodology was applied, and (via the post-processor) emission estimates are based on speeds derived from final assigned volumes. Zonal travel impedances are in reasonable agreement with the final assigned volumes. The model is reasonably sensitive to changes in times, costs and other factors affecting travel choices; (2) reasonable methods were applied to estimate traffic speeds sensitive to estimated volumes on each roadway segment; (3) The network model was reconciled to HPMS data for the base year. 93.126 & 93.127 - Certain types of projects (such as safety projects, transit projects, and intersection improvements) that do not have adverse emission impacts are eempt from being included in the regional emissions analysis and will not be stopped in the absence of conforming LRTP or TIP: o All projects that are eempt under the federal conformity rule and would not typically be included in the regional network model were not included in the regional emissions analysis. Draft Report, May 2012 4-6

DRAFT Regional Conformity Analysis - & Tri-Cities 2035 LRTP and FY 12-15 TIP Conclusion and Conformity Finding Table 4-2 presents the results of the conformity analysis for the 2035 LRTP and FY 12-15 TIP. As indicated in the table, the TIP and LRTP meet all applicable requirements of the federal and state transportation conformity rules. A recommendation for a finding of conformity for the TIP and LRTP is therefore made, but is conditional upon any further and separate review as may be required by the US DOT for the fiscal constraint criterion consistent with Section 93.108 of the federal conformity rule and the requirements of federal planning regulations specified at 23 CFR Part 450.
