Congestion Mitigation and Air Quality (CMAQ) Program

The 2019 CMAQ Funding Round is now closed. The Department received 21 applications requesting approximately 14.5M in CMAQ funds. Applications with location maps can be found at the link below.

CMAQ Applications

Please note that applicants must have submitted a letter of interest and attended one of the mandatory CMAQ workshops to submit a CMAQ Application.

The New Hampshire Department of Transportation (NHDOT) announced the start of the 2019 application cycle for the Congestion Mitigation & Air Quality (CMAQ) program. The CMAQ program is a federally funded reimbursement program that provides up to 80% of funds for projects that improve air quality by reducing the amount of vehicular emissions. There is approximately $13.5 million in federal funding available for this round.

The 2019 CMAQ Application can be downloaded at the following link: 2019 CMAQ Application

The 1991 Intermodal Surface Transportation Efficiency Act (ISTEA) established the CMAQ Program, substantially expanding the focus and purpose of Federal transportation funding and programs to address air quality. The program continued under the current Fixing America's Surface Transportation Act.

Eligible projects or programs for the use of CMAQ funds include those which would result in an air quality benefit and are likely to contribute to the attainment of national ambient air quality standards.

Typical items eligible for funding under this category are:

  • Eligible Activities:
    • Alternative fuel projects including participation in vehicle acquisitions, engine conversions, and refueling or charging facilities.
    • Projects that improve traffic flow, including efforts to provide signal system optimization, construct HOV lanes, streamline intersections, add turning lanes, improve transportation systems management and operations, implementing ITS and other CMAQ-eligible projects, including efforts to improve incident and emergency response or improve mobility, such as through real time traffic, transit and multimodal traveler information
    • Transit investments, including transit vehicle acquisitions and construction of new facilities or improvements to facilities that increase transit capacity, as well as operating assistance for new services or the incremental cost of expanded services.
    • Transportation-focused (non-recreational) bicycle transportation and pedestrian improvements that provide a reduction in single-occupant vehicle travel

Although the projects in any of the above categories are eligible, past projects selected have shown that projects with higher air quality benefits have a higher chance of being selected.

You will find additional links to forms and documents in the Office of Federal Compliance Document Library under Local Public Agency (LPA). You can view or download each component individually or you may also download the entire Federal Aid Package.
