The Transportation Conformity Working Group (TCWG) serves as the
primary forum for interagency consultation on all matters related
to both regional and project-level transportation conformity to
comply with federal transportation and air quality planning
requirements in the six-county SCAG region. The TCWG consists of
staff representatives from FHWA, FTA, U.S. EPA, Caltrans
Headquarters, Caltrans Districts, CARB, CTCs, air districts, and
transit operators in the SCAG region. The group meets monthly on
the fourth Tuesday of the month.
For particulate matter (PM) hot spot interagency consultation,
SCAG staff facilitates the review and determination by TCWG as to
whether a project is a Project of Air Quality Concern (POAQC), as
well as the review and approval of modeling protocols and
subsequent quantitative PM hot spot analysis if and after a
project has been determined to be a POAQC by TCWG.
TCWG discusses, reviews, and makes a determination as to whether
a project is POAQC based on project information included in
the PM Hot Spot Interagency Review Form. The form applies to all
project-level conformity review cases, as the lead agency
requests TCWG’s concurrence that their project is not a POAQC.
Projects exempt from conformity analysis are also determined
through review of the Caltrans Conformity Streamlining Exemption
Form.
If you need to submit a form to TCWG for interagency
consultation, please coordinate with the state and/or local
project representative for your project’s county. Contact
information for project-level conformity representations can be
found in the “Project-Level Conformity Contact List.”
The submissions below include all of the PM hot spot interagency
review forms, qualitative analyses, and quantitative analyses
that have been or will be reviewed by the TCWG. The titles
include the FTIP Project ID, where available, and any
determinations made by the TCWG (e.g., Project of Air Quality
Concern (POAQC)).
