CMAQ Competitive Funding
The 2019 CMAQ Call for Proposals is Opening Soon. For more information on how to apply, see below.
The federal Congestion Mitigation and Air Quality Improvement (CMAQ) program provides dedicated federal funding to state Departments of Transportation for projects that improve air quality and reduce congestion. The CMAQ program improves air quality by funding transportation projects and programs that reduce emissions from onroad mobile sources (cars, trucks, buses, etc.) and certain nonroad mobile sources (such as construction equipment and marine or rail projects) in designated air quality nonattainment and maintenance areas. Funding is broken out into two major portioned allotments, General Competition and PM 2.5.
- Must be a transportation project
- Must be located in (or benefit) either a non-attainment or maintenance area ( eligible areas listed below)
- Must have an emissions reduction benefit
- Applications must be submitted using the online eGrants application software.
- A separate application package is required for each project proposal.
- A Letter of Intent is required for each proposed project.
*Projects must meet ALL criteria listed above.

Projects Eligible for 100% Federal Funds CMAQ Guidance V.F.
Carpooling and Vanpooling Projects
Traffic Flow Improvements/Intelligent Transportation Systems
- Disclaimer: All CMAQ funded projects must include DSRC equipment in the description and budget. Projects shall also be developed to comply with TDOT roadway design standards. Additional work required to address accessibility deficiencies within the limits of project and any ADA upgrades if required may not be eligible for 100% federal funding , addressing such features will require 20% local match. All projects seeking CMAQ funding shall scope and addressing accessibility related issues when putting together project estimates. Refer to roadway design guidelines for additional guidance.
Public-Private Partnerships (PPPs)
As defined by FHWA, a Public-Private Partnership (PPP) is an agreement between a government agency and non-government organization to work together to accomplish a goal that benefits both the taxpaying public and the private partner. To be eligible for CMAQ funding, a PPP project must clearly demonstrate emissions reductions in nonattainment or maintenance areas. The same eligible project types apply to PPPs. These projects are eligible for a 50/50 match, as opposed to the typical 80/20 match. CMAQ Guidance: VII.C
All CMAQ funded projects shall be developed to comply with TDOT roadway design standards. Additional work required to address accessibility deficiencies within the limits of project and any ADA upgrades if required may not eligible for 100% federal funding , addressing such features will require 20% local match. All projects seeking for CMAQ funding shall scope addressing accessibility related issues when putting together project estimates. Refer to roadway design guidelines for additional guidance.
Projects developed by locals and let by locals are also under obligation to follow the same guidance since local agencies are obligated to comply with the FHWA ADA Transition plan requirements by end of 2019. For more guidance, refer to the Roadway Design Division’s ADA Office at
If steel and/or iron materials are to be permanently incorporated into any CMAQ project, all manufacturing processes, including application of a coating, for these materials must occur in the United States. Coating includes all processes which protect or enhance the value of the material to which the coating is applied. This is a Federal Highway Administration requirement. Regulations do permit a minimal use of foreign steel and/or iron in a Federal-aid project in the amount of $2,500 or one-tenth of one percent, whichever is greater.
To learn more about FHWA’s Buy America statutory provisions please refer to 23 U.S.C. 313, and the regulatory provisions in 23 CFR 635.410. Should you have any questions, please refer to FHWA’s Buy America Q and A for Federal-aid Program, or reach out to TDOT.CMAQ@tn.gov.
