STIP Comment Form

Each state is required under 49 U.S.C. 5304(g) to develop a statewide transportation improvement program (STIP) covering a period of at least four years. The STIP is a staged, multi-year, statewide intermodal program of transportation projects, consistent with the statewide transportation plan and planning processes as well as metropolitan plans, transportation improvement programs (TIPs), and planning processes. The STIP must be developed in cooperation with the metropolitan planning organizations (MPOs), public transit providers, and any Regional Transportation Planning Organizations (RTPO) in the state, and must be compatible with the TIPs for the state's metropolitan areas.

INDOT STIP is updated monthly throughout the course of the year for projects additions, advancements, deletions, and other types of modifications. These are accomplished either by a formal STIP Amendment or a Modification.
STIP Amendment - Before FHWA/FTA can approve a STIP Amendment the associated MPO's TIP must also be amended, if the project is within the geographic boundaries of the MPO. Generally, the MPO TIP may only be amended by a formal resolution of the MPO Executive Board. TIPs/STIP require formal amendments based on the following criteria:

  • Adding a new project that was not included in the current STIP
  • Adding a new phase of a project not currently included in the STIP (preliminary engineering, right-of-way acquisition, construction)
  • Changes where project costs have increased or decreased significantly
  • Changes in project scope

The public is encouraged to provide feedback on INDOT's STIP document lists all projects expected to be funded in those four years with Federal funds and those state-funded projects that have been deemed as Regionally Significant. Please use this form to let INDOT know of any roadway transportation improvements that you believe is needed on Indiana’s interstates, U.S. highways or state highways. Your input will enable INDOT to more effectively identify projects and improvements that will enable us to enhance safety and continue to improve Indiana's transportation network.

Draft STIP Documents




The Indiana Department of Transportation (INDOT) has prepared transportation conformity determination report for the project listings in Greene and Jackson Counties in the Fiscal Years 2022 – 2026 Statewide Transportation Improvement Program.  The transportation conformity report documents that the proposed project listings meet the federal transportation conformity requirements in 40 CFR Part 93.  The report was prepared with coordination from the Federal Highway Administration (FHWA), the United States Environmental Protection Agency (EPA), the Federal Transit Administration (FTA) and the Indiana Department of Environmental Management (IDEM).

Clean Air Act (CAA) section 176(c) (42 U.S.C. 7506(c)) requires that federally funded or approved highway and transit activities are consistent with (“conform to”) the purpose of the State Implementation Plan (SIP).  Conformity to the purpose of the SIP means that transportation activities will not cause or contribute to new air quality violations, worsen existing violations, or delay timely attainment of the relevant NAAQS or any interim milestones.  42 U.S.C. 7506(c) (1).  EPA’s transportation conformity rules establish the criteria and procedures for determining whether metropolitan transportation plans, transportation improvement programs (TIPs), and federally supported highway and transit projects conform to the SIP.  40 CFR Parts 51.390 and 93.

On February 16, 2018, the United States Court of Appeals for the District of Columbia Circuit in South Coast Air Quality Mgmt. District v. EPA (“South Coast II,” 882 F.3d 1138) held that transportation conformity determinations must be made in areas that were either nonattainment or maintenance for the 1997 ozone national ambient air quality standard (NAAQS) and attainment for the 2008 ozone NAAQS when the 1997 ozone NAAQS was revoked. These conformity determinations are required in these areas after February 16, 2019. Jackson County was maintenance at the time of the 1997 ozone NAAQS revocation on April 6, 2015 and was also designated attainment for the 2008 ozone NAAQS on May 21, 2012. Therefore, per the South Coast II decision, conformity determination is being made for the 1997 ozone NAAQS on the Burkart Boulevard bypass road project in Jackson County.

The Transportation conformity report for Greene and Jackson Counties is available for review and public comment.

INDOT is accepting public comment regarding the Greene and Jackson County conformity determination.  Please reply no later than Wednesday, June 23rd to Michael McNeil, mmcneil@indot.in.gov Office of Planning, 100 North Senate Avenue, Room N758-Transportation Planning, Indianapolis, Indiana 46204.  You may submit comments by computer at INDOT4U.com or by  phone at 1-855-463-6848 (1-855-INDOT4U).

The conformity determination process completed for Greene and Jackson County demonstrates that projects meet the Clean Air Act and Transportation Conformity rule requirements for the 1997 ozone NAAQS.
