Project-Level Air Quality

Share via:


The Federal Clean Air Act (e.g. Transportation Conformity), the California Clean Air Act, the National Environmental Policy Act (NEPA), and the California Environmental Quality Act (CEQA) require transportation planning and project development to consider air quality as a part of the environment review process. Caltrans coordinates with Federal, State, and regional transportation planning agencies and local air districts to address transportation-related air quality issues. The Department develops policies, guidance, and tools to conduct air quality analyses in compliance with Federal and State regulations. Caltrans also initiates and participates in air quality researches and studies to advance its scientific knowledge and state-of-practice on the subject.

For more information on Transportation Conformity, NEPA, and CEQA, as well as other air quality policies, guidance, forms, and templates, refer to the Caltrans Standard Environmental Reference, Chapter 11 – Air Quality.
