Greenhouse gas: emissions: significant effects: regional transportation plan.

The California Environmental Quality Act (CEQA) requires a lead agency to prepare, or cause to be prepared, and certify the completion of, an environmental impact report on a project, as defined, that it proposes to carry out or approve that may have a significant effect on the environment, as defined, or to adopt a negative declaration if it finds that the project will not have that effect. Existing law requires specified transportation planning agencies to prepare and adopt a regional transportation plan directed at achieving a coordinated and balanced regional transportation system. This bill would authorize a lead agency, in adopting a regional transportation plan for a region in which a residential or mixed-use residential project is located, to use a threshold of significance for greenhouse gas emissions adopted for the residential or mixed-use residential project by the air pollution control district or air quality management district within which the project is located to determine whether the project may have a significant effect on the environment due to the emission of greenhouse gases.
