Project-specific EJ analysis is conducted as part of a NEPA document. Therefore, if the NEPA document needs to be updated (e.g., when there are project changes that have the potential for significant environmental impacts, or a significant project change which was not analyzed previously), the EJ analysis should be reviewed to confirm that there are no new impacts to the EJ population that would be considered disproportionately high and adverse. FTA will re-evaluate the EJ analysis to determine whether additional EJ analysis is required.
