CMAQWelcome to the Congestion Mitigation and Air Quality (CMAQ) Program!

The Bureau of Planning and Community Assistance administers the Congestion Mitigation and Air Quality (CMAQ) Program.  The Program specifically provides assistance for air quality improvement and congestion mitigation projects in urbanized areas which have been identified as “non-attainment”.

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 Transportation Equity Act for the 21st Century, or TEA-21.

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.

Air Quality Fact SheetNon-Attainment Map

Typical items eligible for funding under this category are:

  • Alternative "Clean" Fuels: For CMAQ purposes an "alternative" fuel must reduce emissions to be eligible. These fuels can include natural gas, ethanol, methanol, electricity, hydrogen, bio-diesel and liquified propane gas. Under TEA-21, eligibility can even extend to private companies.
  • Demand Management: Employer trip reduction programs, transportation management plans, flexible work schedule programs, vehicle restriction programs, etc.
  • Education and Outreach: To increase public knowledge of transportation related emissions and opportunities to reduce them.
  • Extreme cold start programs
  • Highway/Road: Traffic flow improvements, signalization projects, intersection improvements and construction or dedication of HOV lanes, ITS efforts, etc.
  • Inspection/Maintenance Programs: (I/M) and Traffic control measures (TCMs) (not covered by the above categories)
  • Other Ride-Share: Vanpool and carpool programs, and parking for shared-ride services, etc.
  • Pedestrian/Bicycle: Sidewalks, trails, storage facilities, promotional activities, etc.
  • Transit: Construction, equipment or operating expenses for new and improved services for a maximum of three years, parking for transit services, etc.

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.

Sample Projects

  • Acquisition of passenger motor coaches to expand commuter bus service to Boston
  • Construction of intermodal park-and-ride facilities in Concord, Portsmouth, and Nashua
  • A statewide Vanpool Incentive Program

  • Establishment of a Transportation Management Association for the Manchester Airport area, with development of traffic-reduction regulations
  • Construction of a system of multi-use paths in Derry connecting schools, recreation, businesses, and residential areas
  • Rehabilitation of an existing railroad bridge for pedestrian and bicycle use along an abandoned railroad corridor in Raymond
  • Development and implementation of a series of public service announcements focused on "clean driving" in New Hampshire
  • Construction of sidewalks in Nashua residential neighborhoods to provide safe routes to schools, reducing automobile and bus trips
  • Modifications to a parking garage in downtown Nashua to become an intermodal transit facility
  • Purchase of a commuter rail locomotive

As a Project Sponsor, there is information you might need to properly implement your project. Things like the NHDOT Manual for Development of Projects, Consultant Selection, Environmental and Right-of-Way documentation requirements, and required Construction Contract Provisions are contained here to allow access anytime you need it. Of course, this site is intended to supplement, not replace, human contact so if you have questions, need clarification, or need more information, please contact us.

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.
