     a. CO TAQA. The purpose of this analysis is to determine if the CO
        impact of proposed transportation projects will adversely affect local air
        quality such that CO levels will exceed the 1-hour or 8-hour CO
        standards.

                    i. If this analysis is required, please refer to the discussion of this
                       analysis in TxDOT’s current Air Quality Guidelines.
                   ii. A CO emissions table will be provided by ENV upon request, if
                       available, which may prevent the need for performing
                       MOBILE6.2 emissions modeling.
                  iii. If the project involves changes to a signalized intersection, then
                       the CAL3QHC dispersion model will need to be used as well as
                       EPA’s 1992 Guidelines for Modeling Carbon Monoxide from
                       Roadway Intersections.
                  iv. Please reference the Air Quality Environmental SOU for
                       template language regarding what needs to be included when
                       submitting the CO TAQA.

         b. Quantitative MSAT Analysis. The purpose of this analysis is to
            provide a relative emissions analysis to compare emission trends for
            the build and no build alternatives to base year emissions.
                i. If this analysis is required, please refer to the discussion of this
                   analysis in TxDOT’s current Air Quality Guidelines, FHWA’s

               ii. If a project has a higher potential for MSAT effects, then a
                   quantitative MSAT assessment may be required and a
                   conference call is required before proceeding. The participants
                   of the conference call should include personnel from: the
                   TxDOT district in which the project will be located, the project
                   sponsor (if different than the District), ENV, FHWA, contractor,
                   and responsible MPO. MPO personnel are included in order to
                   obtain region specific data necessary to conduct the MSAT
                   assessment. Minutes should be prepared by the project
                   sponsor or their contractor following the conference call and
                   distributed to all participants. The project file shall include the
                   details (e.g. emission runs and data inputs) of the quantitative
                   MSAT analysis.          The information addressed during the
                   conference call should include, but not be limited to, the
                   following:
                        1. Project scope, location, and termini
                        2. Demographic information (discussion of nearby populated
                            areas or lack thereof)

                       3. Projected traffic volumes (AADT) and source of traffic
                           data. The availability of a travel demand model that
                           includes the current project description in terms of design
                           concept, scope, and time of completion must be
                           ascertained.
                       4. Determination that the project is consistent with the
                           appropriate transportation plans (e.g. MTP, RTP, TIP,
                           STIP)
                       5. Years to be analyzed (base, interim, design year), as well
                           as months and peak hours to be used
                       6. Affected network (typically the links that change in volume
                           +/- 5 percent from the build to no build scenarios)
                       7. Required model and modeling parameters
                       8. Any other pertinent MSAT or project-related information,
                           including project alternatives to be compared in the
                           MSAT analysis
                       9. If required, discuss CO TAQA analysis years and models
               iii. A quantitative MSAT analysis must use the methodology and
                    parameters established in the conference call.
              iv. Please reference the Air Quality Environmental SOU for a
                    description of what needs to be included when submitting the
                    quantitative MSAT analysis.
         c. Quantitative CO Hot Spot Analysis. This section is currently only
            applicable to the City of El Paso. The purpose of this analysis is to
            determine if the CO impact of proposed transportation projects will
            adversely affect local air quality such that CO levels worsen existing
            conditions or will exceed the applicable CO NAAQS.
                 i. The Consultation Partners (see item 4 below) must make a
                    determination as to whether the project is of “air quality concern”
                    as defined in 40 CFR 93.123(a). If the project is of “air quality
                    concern” then a CO hot spot analysis will be required.
                ii. EPA’s new MOVES emission model will be required for this
                    analysis if it is started after December 20, 2012.
               iii. A quantitative hot spot analysis must address and include any
                    requirements of the Consultation Partners and must be
                    developed in accordance with the December 2010 EPA
                    guidance titled, Using MOVES in Project-Level Carbon
                    Monoxide Analyses.

           iv. The format for a quantitative hot spot analysis will be
                determined by the Consultation Partners on a project specific
                basis.
     d. Quantitative PM Hot Spot Analysis. This section is currently only
        applicable to the City of El Paso. The purpose of this analysis is to
        determine if the PM impact of proposed transportation projects will
        adversely affect local air quality such that PM levels worsen existing
        conditions or will exceed the applicable PM NAAQS.
             i. The Consultation Partners (see item 4 below) must make a
                determination as to whether the project is of “air quality concern”
                as defined in 40 CFR 93.123(b). If the project is of “air quality
                concern” then a PM hot spot analysis will be required.
            ii. Due to the rollout of EPA’s new MOVES emission model, a
                quantitative PM hot spot analysis will be required for projects
                where the hot spot analysis is initiated after December 20, 2012.
                If initiated prior to this, a qualitative PM hot spot analysis will be
                allowed.
           iii. A quantitative hot spot analysis must address and include any
                requirements of the Consultation Partners and must be
                developed in accordance with the December 2010 EPA
                guidance titled Transportation Conformity Guidance for
                Quantitative Hot-spot Analyses in PM2.5 and PM10
                Nonattainment and Maintenance Areas.
           iv. The format for a quantitative hot spot analysis will be
                determined by the Consultation Partners on a project specific
                basis.
4. Consultation Partners.
     a. Background:
             i. A consultation process is required for conformity determinations
                as specified under the federal conformity rule 40 CFR 93.105.
                Texas has developed an interagency consultation process
                under the state transportation conformity rule 30 TAC 114.260.
                Under these rules, the Consultation Partners have the
                responsibility for assisting FHWA/FTA in making conformity
                determinations on transportation plans and projects in CO or
                PM nonattainment/maintenance areas.
            ii. All federally funded or regionally significant projects in
                nonattainment/maintenance areas have to show project level
                conformity. In most cases, this is accomplished by showing that
                the project is included in and consistent with a currently



Standard Operating Procedure                                                2010.01 SOP
TxDOT Environmental Affairs Division
Last Update: September 2012                                                 Page 8 of 13
                   conforming MTP and TIP, or STIP (as previously found to be
                   conforming by the Consultation Partners). In CO and PM
                   nonattainment areas (currently only applies to El Paso), the
                   federal conformity rule also requires an evaluation of whether
                   the project will contribute to a CO/PM hot spot or worsen
                   existing conditions, which is why the Consultation Partners must
                   assist FHWA in making a project level conformity determination
                   on these projects.
              iii. The consultation partners include but are not limited to the local
                   MPO, TxDOT district, ENV, TCEQ, FHWA, and EPA.
       b. The Consultation Partners should be contacted early in the project-
          level planning process because their determination is part of the
          project-level conformity process and requires public involvement,
          which can be combined with NEPA public involvement if initiated early.
       c. If the project is located in a CO/PM nonattainment or maintenance
          area and is not otherwise exempt from conformity, the District or
          project sponsor would need to work with its respective MPO in setting
          up a meeting of the local consultation partners. Additional resources
          regarding the consultation partners and the conformity process can be
          obtained at the following website: www.texastwg.org.
5. Environmental Reviews. If any of the quantitative analyses described in item
   3 above is required for a project, ENV highly encourages the project sponsor
   to coordinate and submit quantitative analyses for approval prior to
   environmental review document submission. Although these may be few in
   number (typically < 25 projects per year); this may reduce risk of project
   delay.
