3 CO TAQA Technical Report I-35E/US 67 Project 1. Introduction The Texas Department of Transportation (TxDOT) proposes improvements to Interstate Highway 35 East (I-35E) from U.S. Highway (US 67) to Interstate Highway 30 (I-30) and along US 67 from Interstate Highway 20 (I-20) to I-35E a total of approximately 11 miles in Dallas County, Texas. The I-35E/US 67 Project (proposed project) has been referred to in the past as the Southern Gateway Managed Lanes Project (see Attachment A, Exhibit 1: Project Location Map) Existing Facility I-35E between Colorado Boulevard (Blvd.) and Reunion Blvd. consists of 5 northbound and 4 southbound mainlanes that include an 11-foot (ft) wide reversible high occupancy vehicle (HOV) lane. This section is currently under construction and was approved as part of the Dallas Horseshoe Project (CSJ , etc.) which received A Finding of No Significant Impact on September 18, Once construction is complete (anticipated 2017), the I-35E northbound bridge will consist of 3 mainlanes; 2 reversible HOV lanes, and 5 Collector-Distributor (CD) lanes, and a 6-ft sidewalk. The I-35E southbound bridge would consist of 4 mainlanes, 4 CD lanes; and 6-ft sidewalks along the outside of the CD road. The right-of-way (ROW) at the Dallas Floodway crossing is approximately 848 ft. wide. On I-35E from US 67 to Colorado Blvd. the existing lane configuration is 8 mainlanes, 4 in each direction; with one reversible HOV lane. I-35E between Fairshop Drive (Dr.) (near the southern limits of construction along I-35E) and US 67 is 6 mainlanes (3 in each direction). South of Colorado Blvd., the existing ROW along I-35E varies from approximately 244 ft to 435 ft. On US 67 from I-20 to I-35E the existing lane configuration is 4 mainlanes, 2 in each direction, with 1 concurrent HOV lane. The existing ROW along US 67 varies from approximately 305 ft to 469 ft. Except for the bicycle accommodations within the section of I-35E between Colorado Blvd. and Reunion Blvd., currently under construction as part of the Dallas Horseshoe Project, no bicycle accommodations exist within the I-35E/US 67 Project limits. Similarly, sidewalks are currently being implemented as part of the Dallas Horseshoe Project. Discontinuous pedestrian accommodations (sidewalks) currently exist within the project limits Proposed Facility The proposed project or Build Alternative would consist of improvements to I-35E between US 67 and Reunion Blvd. and to US 67 between I-20 and I-35E. The improvements would consist of converting the existing HOV lanes to reversible non-toll express lanes, adding reversible non-tolled express lanes and general purpose lanes (mainlanes), along with bicycle and pedestrian accommodations. TxDOT is also CSJs: , etc. 2 June 2016

4 CO TAQA Technical Report I-35E/US 67 Project planning local enhancements consisting of a deck plaza along I-35E, near Ewing Avenue (Ave.). The enhancements would be funded by and maintained by the City of Dallas. I-35E improvements from US 67 to Fairshop Dr. consist of a tie in/transition into the existing facility. The proposed project is shown in Attachment A, Exhibit 1: Project Location Map and described below. a) I-35E between Colorado Blvd. and Reunion Blvd.: Convert 2 existing reversible HOV lanes to 2 reversible non-tolled express lanes. b) I-35E between the US 67 and Colorado Blvd.: Full reconstruction to include two reversible non-tolled express lanes, increasing the number of the mainlanes from 8 to 10, and increasing the number of frontage road lanes from 4 to 4/6. c) US 67 from I-20 to I-35E: Partial reconstruction to change the existing concurrent HOV lane to one reversible non-tolled express lane within the existing median and increasing the number of mainlanes from 4 to 6 along with slip ramp modifications. d) Sidewalks and 14-ft shared use lanes to accommodate vehicles and bicyclists would be implemented along those frontage roads where reconstruction is proposed. e) Dedicated bicycle lanes and sidewalks would be implemented at cross-streets where reconstruction is proposed. 2. Carbon Monoxide Traffic Air Quality Analysis (CO TAQA) This Carbon Monoxide Traffic Air Quality Analysis (CO TAQA) technical report was prepared in accordance to the TxDOT s CO TAQA Standards Operating Procedures, Documentation Standard for a CO TAQA Technical Report, and Standard Operating Procedures for Preparing Air Quality Statements. This report documents results of the CO TAQA analysis, and supports the environmental document that evaluates the social, economic, and environmental impacts resulting from the proposed project. The Build Alternative was evaluated in 2021, the estimated time of completion (ETC), and in 2037, the design year Background If a roadway project is not exempt under 40 Code of Federal Regulations (CFR) , is adding capacity and would reach average annual daily (AADT) traffic greater than 140,000 by the design year, a CO TAQA is required. Because the proposed project would not be exempt per 40 CFR , would increase capacity, and the AADT for the ETC (2021) and design year (2037) is above 140,000 vehicles per day (vpd), a CO TAQA is required. Specifically, traffic for the ETC year (2021) for I-35E and US 67 is estimated to be 218,000 vehicles per day (vpd) and 125,000 vpd, respectively. Traffic for the design year (2037) for I-35E and US 67 is estimated to be 311,400 vpd and 192,800 vpd, respectively. A consultative call between TxDOT and the North Central Texas Council of Governments (NCTCOG) to discuss the CO TAQA methodology and assumptions was held on January 26, Notes from the coordination call are CSJs: , etc. 3 June 2016

5 CO TAQA Technical Report I-35E/US 67 Project available in Attachment B. The methodology and assumptions for this CO TAQA were determined during the call Analysis Methodology and Assumptions Carbon monoxide concentrations for the proposed project were modeled using CALINE3 and MOVES2010b and factoring in adverse meteorological conditions and sensitive receptors at the ROW line in accordance with the Standard Operating Procedure (SOP) for Complying with CO TAQA Requirements. The traffic data and K factor utilized in the analysis were obtained from the TxDOT Transportation Planning and Programming Division (TP&P) approved on June 3, 2016 (Attachment B: Traffic Data), to determine if the CO concentrations exceed the National Ambient Air Quality Standards (NAAQS) in the ETC and design years. The traffic data utilized in the analysis for each roadway segment analyzed for both ETC and design year is included in Table 2-1.

14 I-35E/US 67 PROJECT Air Quality Consultative Call Date: January 26, 2016, 1:30pm MEETING NOTES Attendees: Ashton Strong (TxDOT), John Nguyen (TxDOT), Sandra Williams (TxDOT), Tim Wood (TxDOT), Sandy Wesch (NCTCOG), Berrien Barks (NCTCOG), Rusty Ozmer (HNTB), Lupe Pettit (HNTB). The participants were provided with the following project information and proposed modeling methodology for MSAT and CO. The group was also provided with a project location map and 2003 approved traffic showing ADT above 140,000 ADT. A summary of the items discussed and decisions made are included on pp.2 and Background: Since the last air quality consultative call held on August 14, 2015, the project limits and scope have changed. The project will require a quantitative MSAT analysis because it is an increase capacity project with over 140,000 ADT and is federally funded. The following describes the proposed project as of January Limits: I-35E from US 67 to Reunion Blvd. and US 67 from I-20 to I-35E for a project length of approx. 11 miles (see Exhibit 1: Project Location Map); 1.2. Proposed improvements: The improvements would consist of conversion of existing HOV lanes to reversible non-toll express/managed lanes, addition of reversible non-tolled express/managed lanes, and addition of general purpose lanes, along with bicycle and pedestrian accommodations as follows: a) I-35E between Colorado Blvd. and Reunion Blvd.: Convert two reversible HOV lanes to two reversible non-tolled express/managed lanes. b) I-35E between the US 67 and Colorado Blvd.: Full reconstruction to include two reversible non-tolled express/managed lanes, widening of the mainlanes from 8 to 10, and increasing the number of frontage road lanes. c) US 67 from I-20 to I-35E: Partial reconstruction to change the existing concurrent HOV lane to one reversible non-tolled express/managed lane within the existing median and widening the mainlanes from 4 to 6 along with slip ramp modifications. d) Full reconstruction of the I-35E/US 67 Interchange Planning: The project will be consistent with the 2040 MTP and STIP currently under development Environmental document: EA per workshop held With FHWA and ENV on June 13, Construction Begin: ETC: MTP Horizon Yr: Anticipated FONSI: December Traffic: Per attached TP&P traffic from 2003 that traffic within project limits is over 140,000 ADT in year Traffic updates are in progress and are anticipated to be above 140,000 ADT. 2. Proposed methodology for MSAT 2.1. MSAT methodology: link-by-link/quantitative MSAT 2.2. Affected transportation network threshold: links with traffic changes between Build and No-build scenarios of +/- 5% CSJ: , etc. 1 January 2016

15 2.3. MSAT study area: NCTCOG MPA affected transportation network 2.4. Analysis years/scenarios: Base year (2017), 2040 Build, and 2040 No-Build with no interim year Traffic data: Mobility 2040 MTP 2017 and 2040 networks 2.6. Pollutants: acrolein, benzene, 1,3-butadiene, diesel particulate matter plus diesel exhaust organic gases (DPM), formaldehyde, naphthalene, and polycyclic organic matter Data Needs: +/-5% affected network and MSAT emissions factors processed with MOVES2010b (if generated before Oct. 7, 2016) or with MOVES2014 (if generated after Oct. 7, 2016). To be provided NCTCOG by 4/29/ Proposed methodology for TAQA (CO analysis) 3.1. Analysis years/scenarios: 2021 (ETC year) and 2040 (MTP horizon year) 3.2. Data Needs: MOVES emission factor look up tables from ENV, traffic data (TP&P approved traffic numbers). The scenario traffic numbers will be derived from the TP&P approved numbers CO Model: CALINE3/CAL2001 (TxDOT s software) 4. Additional Items of discussion: 4.1. Project level toll analysis: Not needed because no tolling component Conformity report would be submitted to FHWA as early as possible for FHWA review and approval once the 2016 conformity is approved by FHWA. Summary of discussion/decisions: Ashton inquired about an additional reversible managed lane along US 67 in 2040 that had been mentioned in Sandy s but was not shown in the draft MTP tables. Sandy said that the MTP tables are incorrect for US 67 (year 2040). They currently show 1R but should be 2R and will be revised. MSAT: Tim and Sandy discussed the proposed MSAT out-year scenario year. Sandy disagrees with the proposed year of 2040 because that network would not reflect the proposed project (3-1R-3), but the ultimate configuration for US 67 (3-2R-3). Sandy was concerned about inconsistency in the EA, which would clear the interim configuration, not the ultimate configuration and from the conformity point of view. Tim clarified that conformity would not apply to MSAT and explained that the purpose of the 2040 scenario is to show the trend of MSAT emissions mainly for comparison purposes, and that it is common for environmental documents to have different analysis years for different resources. It was mentioned that the schematic will use 2017 and 2037 traffic. Traffic noise would be modeled for these same years. Tim stated that for MSAT TxDOT uses the MTP horizon year for the out year. He also explained the difference between the project and the corridor. Tim added that the no-build 2040 scenario would consist of removal of the proposed project and would leave all other projects as proposed in The group discussed what is involved in coding of the no-build scenario. Although atypical, and to avoid confusion, TxDOT agreed to complete the MSAT for 2037 instead of 2040 (MTP horizon year) because the project is environmentally being cleared as an interim project. In summary: o MSAT scenario years are 2017 (base), 2037 no-build, and 2037 build o The affected network would be based on the +/-5% threshold and will be provided by NCTCOG. CSJ: , etc. 2 January 2016

16 o NCTCOG will provide emissions for the MSAT analysis. For this purpose, NCTCOG will use the MSAT emission factors provided by Tim, which were determined using MOVES2010b. Tim advised that once MOVES2014 is required, TxDOT will provide updated emission tables. This requirement will come into effect on Oct. 7, CO: The group agreed that the proposed scenarios for the CO analysis should be 2021 (ETC) and 2037 (design year) using the CALINE3/Cal2001. TPP approved traffic numbers will be used of the CO analysis. TxDOT emission lookup tables available in the air quality toolkit online shall be used in the analysis. Schedule: Sandy said that the MSAT data would be provided in April of It is anticipated that the RTC will approve the MTP in March of Conformity is anticipated to be approved by FHWA in June/July CSJ: , etc. 3 January 2016
