Project Level Conformity

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)).
