What triggers a Conformity Analysis?
The following actions initiate the need for a Conformity Analysis:
- Establishment or Revision of the Emissions Budget. The State or Federal Government determines this need.
- Long Range Transportation Plan adoption or amendment
- Establishment or revision of Traffic Control Measures.
- For maintenance areas, a Conformity Analysis is required every 3 years.

In short, a new analysis is required whenever the transportation plan adds a project, deletes a project, significantly delays or accelerates a project, or changes the project scope.
