Funded Projects

Examples of what this program has supported.

FY2025 EPA Awards under this program have assisted in the development and planning of programs that continue to prevent and control air pollution across the country as well as the implementation of national primary or secondary air quality standards.

Program Objective

The objectives of the §105 program are to assist state, tribal, municipal, intermunicipal, and interstate air pollution control agencies in planning, developing, establishing, improving, and maintaining adequate programs for the continuing prevention and control of air pollution, and/or in the implementation of national primary and secondary air quality standards. The continuing activities funded under Section 105 include: analysis and planning for attainment and maintenance of NAAQS; emission reduction measures; development and operation of air quality monitoring networks, and other air program activities. Specific expectations and deliverables are established through negotiations in grant agreements between regions and air pollution control agencies. EPA is prepared to work collaboratively with air agencies to adjust resources to meet changing priorities. The Office of Air and Radiation's National Program Guidance identifies key priorities and activities expected to be undertaken by EPA Headquarters and Regional offices and implementing air agencies in national areas of focus. OAR’s current NP Guidance can be found at https://www.epa.gov/planandbudget/national-program-guidances. The monitoring guidance outlines monitoring priorities, quality assurance programs, and funding projections. The monitoring appendix may be accessed at https://www.epa.gov/amtic/national-program-manager-npm-guidance-monitoring-appendix.

Description

Mission Categories

Primary: Air Pollution Control

Use of Funds

Allowed Uses

Grant funds may be used for costs specifically incurred in the conduct of a state/local/tribal air pollution control program in accordance with the purposes enumerated in the approved application. These include personnel costs, supplies, equipment, personnel training, travel, and other necessary expenditures during the approved project period. Funds may not be used for construction of facilities, nor for expenses incurred other than during each approved award period. Grant funds may not be used to subsidize the costs of Title V operating permit programs or to supplant otherwise available recipient resources.

Restrictions

Funds may not be used for construction of facilities, nor for expenses incurred other than during each approved award period. Grant funds may not be used to subsidize the costs of Title V operating permit programs or to supplant otherwise available recipient resources.

Required Documentation

The application must supply evidence of legal authority for air pollution control including responsibility for carrying out the implementation plan requirements under §110 of the Clean Air Act; evidence of the availability of nonfederal matching funds; assurance that federal funds do not supplant available recipient funds; evidence that the Governor or his designated state agency has been given the opportunity to comment on the relationship of the program to be funded to the state plan; and a workable program officially adopted for the agency.

Matching Requirements

The Clean Air Act does not prescribe a specific statutory funding formula but does direct that the factors of population, the extent and severity of the air pollution problem, and financial need, be considered in the allocation of available resources by the Agency. State, interstate, and local programs may receive up to 60% federal funding for the total approved program costs. The non-tribal grantee must contribute a minimum of 40% as well as meet a maintenance of effort (MOE) requirement. The amount of federal share of grant costs should be determined by reference to the criteria set forth in Section 105 of the Clean Air Act and in 40 CFR 35.145, 40 CFR 35.146, and 40 CFR 147. Not more than 10% of the total of funds appropriated for Section 105 grants shall be granted for air pollution control programs in any one state. Not less than one-half of one % of the annual appropriations are to be made available to a state for application. EPA can award less than the 0.5% level if the level of funding is not justified in the work plan. For Indian tribes establishing eligibility pursuant to Section 35.573, the Regional Administrator may provide financial assistance in an amount up to 95% of the approved costs of planning, developing, establishing, or improving an air pollution control program, and up to 95% of the approved costs of maintaining that program. After 2 years from the date of each tribe's initial grant award, the Regional Administrator will reduce the maximum federal share to 90%, as long as the Regional Administrator determines that the tribe meets certain economic indicators that would provide an objective assessment of the tribe's ability to increase its share.

This program has MOE requirements, see funding agency for further details. This program does have a maintenance of effort (MOE) requirement which requires that a recipient's recurring expenditures must meet or exceed the level of the prior year's recurring expenditures.
