DVRPC encourages the public to submit comments on the Draft Transportation Conformity Demonstration: Connections 2050 Long-Range Plan and Draft FY2025 TIP for Pennsylvania by submitting comments on this webpage; by email to airconformity@dvrpc.org; or by mailing to DVRPC at the address at the bottom of this page, Attention: Conformity Comments. If you are unable to submit comments by these standards, please contact DVRPC at (215) 592-1800 for assistance. After consideration of public comment, the DVRPC Board may adopt the conformity determination with any recommended changes at its July 25, 2024 meeting.

The Federal Clean Air Act and the transportation planning provisions of Title 23 and Title 49 of the United States Code are intended to ensure that integrated transportation and air quality planning occurs in the areas that do not or previously have not met the National Ambient Air Quality Standards (NAAQS).  These areas, known as nonattainment or maintenance areas respectively, require a process to demonstrate that transportation projects included in the region’s Long-Range Plan (Plan) or Transportation Improvement Program (TIP) will not impede a region’s progress towards meeting or maintaining the federal air quality standards.

Transportation conformity is the federally mandated analytical process through which Metropolitan Planning Organizations (MPOs) demonstrate that the transportation investments, strategies, and programs included in the Plan and TIPs are consistent with air quality goals established in State Implementation Plans (SIP) for achieving the NAAQS. Conformity demonstrations show that emissions from projects in transportation plans and programs do not exceed the SIP targets ("budgets") for emissions from mobile sources.

The nine-county DVRPC planning area is part of the:

  • Philadelphia-Wilmington-Atlantic City Ozone Nonattainment Area
  • Philadelphia-Wilmington, PA-NJ-DE PM2.5 Maintenance Area
  • New York - Northern New Jersey - Long Island, NY-NJ-CT PM2.5 Maintenance Area
  • Delaware County PM2.5 Maintenance Area

On September 28, 2023, the DVRPC Board adopted the “Transportation Conformity Determination:  Connections 2050 Long-Range Plan, FY 2024 New Jersey and FY 2023 TIP for Pennsylvania.” This is the current transportation conformity determination for the New Jersey and Pennsylvania portions of the region.

The Air Quality Conformity presentation given to the DVRPC Board on September 28, 2023, is available at this link.
