We follow the process that is detailed in our approved Public Involvement Plan (PIP) to manage all changes to the current, approved Duluth and Superior Area TIPs.
Not every project change triggers a formal amendment process. Using definitions in 23CFR 450.104 and applying MnDOT’s STIP cost change guidelines, the MIC determines whether a change is processed as an Amendment or an Administrative Modification.
Amendments are used for major changes, such as adding or deleting a project, cost increases or decreases that meet MnDOT’s thresholds, or significant revisions to project scope or initiation dates.
- Amendments require Policy Board, state and federal approvals, public review and comment, and a redemonstration of fiscal constraint.
Administrative Modifications address minor adjustments, including small changes to project costs (below MnDOT’s thresholds), project funding sources, or project initiation dates.
- Administrative Modifications do not require approvals, public review and comment, or a redemonstration of fiscal constraint.
