Transportation Conformity Working Group - Before 2105
The Transportation Conformity Working Group (TCWG) is a regional forum for interagency consultation and coordination to maintain transportation conformity and improve air quality in Southern California.
The TCWG meets monthly to facilitate inclusive transportation and air quality planning processes and to fulfill the interagency consultation requirements of Federal Transportation Conformity Regulations. The group helps resolve regional issues pertaining to transportation conformity and coordinates with the Statewide Transportation Conformity Working Group.
Membership of the TCWG includes federal (U.S. Environmental Protection Agency, Federal Highway Administration, Federal Transit Administration), state (California Air Resources Board, Caltrans), regional (air quality management districts, SCAG), and subregional (county transportation commissions) agencies and other stakeholders.
