EPA Region 5 awarded $974,614 to the Indiana Department of Environmental Management on April 1, 2026, under the Surveys, Studies, Research, Investigations, Demonstrations, and Special Purpose Activities Relating to the Clean Air Act program (CFDA 66.034) to operate and maintain a statewide ambient air quality monitoring network for fine particulate matter.

IDEM will collect quality-assured PM2.5 concentrations data from air sampling and submit results to EPA's National Air Quality Database. The monitoring network consists of federal reference method samplers, a continuous PM2.5 network, and speciation samplers and instrumentation. The collected data will support PM2.5 National Ambient Air Quality Standards comparisons, development and tracking of state implementation plans, regional haze assessments, and health studies and ambient aerosol research activities. Expected outcomes include increased knowledge of PM2.5 character and extent in Indiana's ambient air and, through eventual implementation plan execution, reduced PM2.5 concentrations and compliance with PM2.5 NAAQS under the Clean Air Act.

Performance occurs in Indiana with administrative oversight at IDEM headquarters in Indianapolis. The period of performance runs from April 1, 2026, through March 31, 2028. No subawards are included in this assistance agreement.

This agreement provides funding to indiana department of management to assist with necessary development, establishment, and maintenance of adequate monitoring programs for the prevention and control of air pollution or implementation of national primary and secondary air quality standards. This grant is provided to conduct ambient air quality monitoring of fine particulate matter. Specifically, the recipient will collect quality assured data on ambient air concentrations of PM2.5, as well as chemical composition and precursors. Data will be used for: (1) PM2.5 national ambient air quality standards comparisons, (2) development and tracking of implementation plans, (3) assessments of regional haze, and (4) assistance for health studies and other ambient aerosol research activities. The PM2.5 monitoring network design addresses these four program objectives through a combination of siting and instrumentation strategies. Activities:the recipient will collect quality assured PM2.5 concentrations data from air sampling and submit results to EPA's national air quality database. Through this grant agreement, the indiana department of environmental management will operate and maintain its PM2.5 air monitoring network, which consists of federal reference method samplers, a continuous PM2.5 network, and speciation samplers and instrumentation. Subrecipient:no subawards are included in this assistance agreement.outcomes:the anticipated deliverables include quality assured PM2.5 concentrations data from air sampling and submit results to EPA's national air quality database. The expected outcomes include an increase in the knowledge regarding the character and extent of PM2.5 in the ambient air. Additionally, through the eventual development and execution of the state's implementation plan, idem expects reduced PM2.5 concentrations and compliance with the PM2.5 naaqs as set forth in the clean air act. The intended beneficiaries are indiana state residents, who will have decreased risk of adverse health effects from PM2.5 exposure.
