Transportation Control Measure Substitution: Dallas-Fort Worth US 67/IH 35 HOV Clean Air Act Section 176(c)(8)

1 of 9

1. Reason for the Transportation Control Measure Substitution

The North Central Texas Council of Governments (NCTCOG) is developing a new long-range transportation plan, Mobility 2040: Metropolitan Transportation Plan for North Central Texas (Mobility 2040). As a result of changing transportation needs, the high-occupancy vehicle (HOV) lane on US 67/IH 35 between IH 20 and IH 30, “Southern Gateway,” will be replaced with an express lane. Since the opening of the HOV in 2000, increased congestion in this corridor, due to an increase in population and vehicle miles traveled, has resulted in the HOV lane no longer providing the needed congestion relief and associated air quality benefits. After 16 years, the Southern Gateway has reached the end of its design life, making it necessary to convert the HOV lane to an express lane. Initially, NCTCOG’s Mobility Plans called for the HOV lane to be converted to tolled lanes, but a recent increase in funding has allowed the installation of toll-free express lanes in this corridor.

The Southern Gateway, located in Dallas County (see Exhibit 1), was first included in Mobility 2025 - 2001 Amendment as an HOV lane, and it was subsequently adopted into the Dallas-Fort Worth 1-Hour Ozone Attainment Demonstration State Implementation Plan Revision in April 2000 as a transportation control measure (TCM). The HOV lane was also listed as a TCM commitment in the 2007 Dallas-Fort Worth 1997 8-Hour Ozone Attainment Demonstration State Implementation Plan Revision. Since the HOV lane is included in the State Implementation Plan (SIP) as a TCM, removing it requires substituting an alternate TCM that achieves an equivalent emissions benefit calculated using the Environmental Protection Agency’s (EPA) Motor Vehicle Emissions Simulator 2014 (MOVES2014) model and the Texas Transportation Institute’s (TTI) Accepted Guide to Mobile Source Emissions Reduction Strategies (MoSERS).

2. Proposed Traffic Signalization Project for the TCM Substitution Traffic signal improvements, such as signal retiming and signal coordination, can enhance traffic flow and help decrease vehicular emissions. Inventorying existing and future projects, NCTCOG has identified several corridors in the nonattainment region where recent traffic signal improvements were completed from December 2015 – February 2016. These improvements result in a more consistent travel speed and reduced delay, which decreases on-road mobile emissions due to frequent starts, stops, and unnecessary idling. NCTCOG used MOVES2014 to calculate the nitrogen oxide (NOX) and volatile organic compound (VOC) emission factors for light-duty vehicles on freeways at 43 miles per hour (mph) and 51 mph to be applied to the HOV calculation methodology provided in MoSERS (see Attachment 1) in order to determine the emissions impact on removing the Southern Gateway TCM project. The results of this calculation shows removing the HOV lane will require 0.04 tons per day (tpd) of NOX and 0.02 tpd of VOC emission offsets to meet the EPA TCM substitution requirements. NCTCOG also calculated NOX and VOC emission factors for all vehicle types on arterial roadways at 5 mph and 9 mph to be applied to the Traffic Signalization by Corridor methodology in order to determine the emissions benefit from implementing the two traffic signalization projects. The three traffic signalization projects to be used as substitutes are:

1. Greenville Ave., eight signals, from County Club Rd. in Fairview to Chaparral Rd. in Allen; 2. Gaston Ave., 16 signals, from Richmond Ave. to Hall St. in Dallas; and 3. Abrams Rd./Columbia Ave./Main St., 11 signals from Belmont Ave. to Haskell Ave. in Dallas. Using the same MoSERS methodology (see Attachment 1), NCTCOG estimated a 0.08 tpd reduction in NOX emissions and 0.04 tpd reduction in VOC emissions for the signals included in the three corridors.

Emissions Impact of

Removing US 67/IH 35 HOV Emissions Impact of Corridor

NOX +0.04 tpd -0.08 tpd

VOC +0.02 tpd -0.04 tpd

The 35 traffic signal locations are incorporated into NCTCOG’s current Transportation Improvement Plan (2015-2017). The City of Allen and the City of Fairview completed the traffic signalization project on March 17, 2015, and the City of Dallas completed the traffic signalization projects on May 14, 2016. To complete this TCM substitution to remove the Southern Gateway HOV TCM, the partner agencies: EPA, the Texas Commission on Environmental Quality (TCEQ), Texas Department of Transportation (TxDOT), Federal Highway Administration, and NCTCOG will follow the guidance developed by EPA, Guidance for Implementing the Clean Air Act Section 176(c)(8) Transportation Control Measure Substitution and Addition Provision, January 2009.
