Short Description
The CMAQ Program provides funding to State and local governments for transportation projects and programs designed to help meet the requirements of the Clean Air Act.
Subject Area
Government Services
Program Function
Enabling Legislation
23 USC 149, MAP-21
Objectives and Goals
Funding is available to reduce congestion and improve air quality for areas that do not meet the National Ambient Air Quality Standards for ozone, carbon monoxide, or particulate matter (nonattainment areas) and for former nonattainment areas that are now in compliance (maintenance areas).
Types of Assistance
Project Grants
Uses and Restrictions
Funds may be used for a transportation project or program that is likely to contribute to the attainment or maintenance of a national ambient air quality standard, with a high level of effectiveness in reducing air pollution, and that is included in the metropolitan planning organization’s (MPO’s) current transportation plan and transportation improvement program (TIP) or the current state transportation improvement program (STIP) in areas without an MPO.

Eligibility Requirements
The FAST Act added eligibility for verified technologies for non-road vehicles and non-road engines that are used in port-related freight operations located in ozone, PM10, or PM2.5 nonattainment or maintenance areas funded in whole or in part under 23 U.S.C. or chapter 53 of 49 U.S.C. [23 U.S.C. 149(b)(8)(A)(ii)]

The Act also specifically makes eligible the installation of vehicle-to-infrastructure communications equipment. [23 U.S.C. 149(b)(9)]

The FAST Act continues eligibility for electric vehicle and natural gas vehicle infrastructure and adds priority for infrastructure located on the corridors designated under 23 U.S.C. 151. [23 U.S.C. 149(c)(2)]

The FAST Act amended the eligible uses of CMAQ funds set aside for PM2.5 nonattainment and maintenance areas. PM2.5 set-aside funds may be used to reduce fine particulate matter emissions in a PM2.5 nonattainment or maintenance area, including–
•diesel retrofits;
•installation of diesel emission control technology on nonroad diesel equipment or on-road diesel equipment that is operated on a highway construction projects; and
•the most cost-effective projects to reduce emissions from port-related landside nonroad or on- road equipment that is operated within the boundaries of the area. [23 U.S.C. 149(k)(2) & (4)]


Grant recipients and subrecipients are authorized to use one of the following three methods described in 2 CFR 200 to charge indirect costs to Federal projects and activities:
• Indirect cost rate and indirect cost allocation plan,
• Indirect cost allocations not using rates (Narrative Cost Allocation Methodology), or
• De Minimis rate of 10 percent of modified total direct costs.


Entities not in good standing with the state of Illinois's secretary of state or those who are not accurately registered through the Illinois GATA portal will not be eligible for consideration. MPO specific restrictions may exist, refer to the CMAQ program page for the given area you are applying.

A State may obligate funds apportioned to it under section 104(b)(4) for the congestion mitigation and air quality improvement program only for a transportation project or program if the project or program is for an area in the State that is or was designated as a nonattainment area for ozone, carbon monoxide, or particulate matter under section 107(d) of the Clean Air Act (42 U.S.C. 7407(d)) and classified pursuant to section 181(a), 186(a), 188(a), or 188(b) of the Clean Air Act (42 U.S.C. 7511(a), 7512(a), 7513(a), or 7513(b)) or is or was designated as a nonattainment area under such section 107(d) after December 31, 1997, or is required to prepare, and file with the Administrator of the Environmental Protection Agency, maintenance plans under the Clean Air Act (42 U.S.C. 7401 et seq.) and—

(1)(A)(i) if the Secretary, after consultation with the Administrator determines, on the basis of information published by the Environmental Protection Agency pursuant to section 108(f)(1)(A) of the Clean Air Act (other than clause (xvi)) that the project or program is likely to contribute to—

(I) the attainment of a national ambient air quality standard; or

(II) the maintenance of a national ambient air quality standard in a maintenance area; and
23 U.S.C. 149 (b)

Only two urbanized ares in Illinois qualify under this provision. Those areas are the Chicago Urbanized Area and the St. Louis Urbanized Area. The Metropolitan Planning Organizations in each of these areas assit the Department in project selection and award. Each area has a different application period and criteria.
