Congestion Mitigation and Air Quality (CMAQ) Program

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.


Results of the 2017 CMAQ applications have been scored by Department Staff from the Bureaus of Planning and Community Assistance, Finance and Contracts, Rail and Transit, and Highway Design. In addition, Air Quality Analyses were developed in accordance with methodologies agreed to by AQ subject matter experts from NHDOT, NHDES, FHWA and the 4 MPOs throughout the State. The results of all of this work for each application allowed for a score for each project. The results were presented to the Governor’s Advisory Commission on Intermodal Transportation (GACIT) on December 6, 2017. Project scores are currently being reviewed by the GACIT members and we anticipate a final decision to be made at the next GACIT meeting on December 20, 2017.

GACIT 2017 CMAQ Project Score

The 2017 CMAQ application round ended on Oct. 20, 2017 and the Department received 23 CMAQ applications from 18 sponsors.   The submitted applications are below.  The Department will be working with each project sponsor to develop an individual air quality analysis.  All the applications will be scored by the Department and results will be submitted to the Governor’s Advisory Commission on Intermodal Transportation for their final approval.


The New Hampshire Department of Transportation (NHDOT) announces the start of the 2017 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.

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 the CMAQ Advisory Committee favor projects with higher air quality benefits.
