- What it does
- 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.

How to read these numbers
- Committed through this program
Money committed under this assistance listing (its CFDA program), counted in the year each action happened.
- How it's paid
Most programs pay out one way — a grant, or a direct payment to individuals; the flow bar only appears when a program genuinely mixes types.
- Some recipients aren't itemized
For entitlement programs like Social Security and Medicare, the government reports one aggregate instead of naming tens of millions of people, so the recipient roster isn't part of the public record.
- Awards, counted once
An award count is the number of distinct awards with at least one action that year — each counted once, however many times it was amended.
- The colored bars
Every bar on this page splits by how the money moves:
