Air Pollution Control Program Support

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.
