Transportation Conformity: A Basic Guide for State and Local Officials

Project-level Conformity and Hot-spot Analysis

Project-level conformity determinations must be made for Federal highway and transit projects to demonstrate that the project is reflected in a conforming metropolitan transportation plan and TIP. Additionally, as part of these project-level determinations, in carbon monoxide and particulate matter nonattainment and maintenance areas, localized analysis requirements apply for Federally-funded or approved projects. This analysis is called "hot-spot" analysis.
