About this program

The Environmental Protection Agency funds state, tribal, municipal, and interstate air pollution control agencies to plan, develop, establish, improve, and maintain air quality programs under the Air Pollution Control Program Support (CFDA 66.001), with the most recent award issued on January 1, 2027.

The program finances ambient air quality monitoring networks, permitting and enforcement of stationary and mobile emission sources, hazardous air pollutant reduction, state implementation plan development, emissions inventory maintenance, and regulatory development to achieve and maintain national ambient air quality standards. Recent awards reflect direct support for these core activities across state environmental agencies, county and municipal air districts, and tribal air programs. Recipients conduct real-time data collection, upload quality-assured monitoring data to the EPA's Air Quality System, issue air permits, conduct compliance inspections, and provide community outreach on air quality issues. Tribal programs emphasize monitoring for wildfire smoke impacts, woodstove emissions, and diesel pollutants alongside federal air rules implementation on reservations.

Funding concentrates overwhelmingly with the Environmental Protection Agency central office, which awarded 1,536 grants totaling $1.52 billion federal dollars obligated (86 percent of the portfolio by count). EPA Regions 9, 3, 5, and 4 account for an additional $316.4 million combined across 172 awards. Combined federal and non-federal obligation totaled $10 billion, indicating significant state and local cost-sharing commitments from recipients.

The assistance mix is predominantly Formula Grants (572 awards, 32 percent) and Project Grants (1,188 awards, 67 percent), with minimal Cooperative Agreements (12 awards, 1 percent). Award magnitudes span from small tribal and municipal programs ($100 thousand to $300 thousand) to large state and regional air district awards. Pennsylvania Department of Environmental Protection received $12.7 million; New York State Department of Environmental Conservation, $15.561 million; and South Coast Air Quality Management District (California), $159.8 million. The portfolio spans 1,772 grants since 1996, with recent activity showing 46 awards in 2024, 22 in 2025, 3 in 2026, and 1 award in 2027, indicating stable but modest annual funding flow.

No recent open grant opportunities are present in the source. The program operates as a continuing non-competitive formula allocation to designated state and tribal air agencies, with applications evaluated administratively by EPA regional offices in consultation with state governors as mandated by Section 105 of the Clean Air Act and 40 CFR 35.140–148.

Criteria for selecting proposals

The criteria for awarding air pollution control program assistance grants are provided in Section 105 of the Clean Air Act. Additional criteria for state and local air pollution control agencies are available in 40 CFR 35.140 through 148. Some of the criteria considered for award to state and local agencies include the following: 1) No grant may be awarded unless the program contained in the grant application meets the requirements of 40 CFR 35.140 (program purposes and associated regulations) and has been approved by the Regional Administrator. 40 CFR 35.104 and 35.107 describe what an agency needs to do to prepare an adequate application. This usually includes the use of annual program technical and grant guidance from EPA and is generally done in consultation with the EPA Regional Office. 2) No grant may be awarded until the Regional Administrator has consulted with the official designated by the Governor(s) of the state(s) affected by such award pursuant to Section 105(b) of the Clean Air Act. Such consultation should consider the role of the applicant in the enforcement of any applicable implementation plan and confirm that the applicant's program will be generally compatible with the objectives of the applicable implementation plan. 3) No grant may be awarded unless the Regional Administrator has determined that the agency has adequate air pollution control authority and necessary regulations to implement such authority. The requirements for awarding Section 105 grants to tribal air pollution control agencies are described in 40 CFR 35.570 through 578.

Award procedure

For competitive awards, EPA will review and evaluate applications submissions in accordance with the terms, conditions, and criteria stated in the competitive announcement. Competitions will be conducted in accordance with EPA policies/regulations for competing assistance agreements. For non-competitive awards made under this assistance listing, EPA will conduct an administrative evaluation to determine the adequacy of the application in relation to grant regulations and to technical and program evaluation to determine the merit and relevance of the project. The Agency will then advise the applicant if funding is being considered. A final work plan will then be negotiated with the applicant.

Time to approval or disapproval
