Federal Project Grant Award Summary

The Environmental Protection Agency (EPA) Region 5 awarded $779,636 to the Indiana Department of Environmental Management under the Surveys, Studies, Research, Investigations, Demonstrations, and Special Purpose Activities Relating to the Clean Air Act program (CFDA 66.034) on April 1, 2026. This project grant funds the development, establishment, and maintenance of ambient air quality monitoring programs focused on fine particulate matter (PM2.5) throughout Indiana. The grant supports the collection of quality-assured PM2.5 concentration data from air sampling activities, including chemical composition and precursor analysis, which will be submitted to the EPA's National Air Quality Database.

The Indiana Department of Environmental Management will operate and maintain a comprehensive PM2.5 monitoring network consisting of Federal Reference Method samplers, continuous PM2.5 monitoring instrumentation, and speciation samplers. The collected data will support four primary objectives: PM2.5 National Ambient Air Quality Standards comparisons, development and tracking of state implementation plans, regional haze assessments, and assistance for health studies and ambient aerosol research activities. The anticipated deliverables include quality-assured PM2.5 concentration data and increased knowledge regarding PM2.5 levels in Indiana's ambient air, with expected long-term outcomes of reduced PM2.5 concentrations and compliance with Clean Air Act standards, ultimately benefiting Indiana state residents. The award extends through March 31, 2028, with no sub-awardees identified in the assistance agreement.
