The U.S. Environmental Protection Agency (EPA) Region 5 awarded a $1,110,081 Project Grant to the Illinois Environmental Protection Agency (IEPA) under the Surveys, Studies, Research, Investigations, Demonstrations, and Special Purpose Activities Relating to the Clean Air Act (CFDA 66.034) program. The funding will be used to replace aging air monitoring and quality assurance audit equipment in order to maintain and enhance IEPA's existing multipollutant air monitoring operations. Many of the sites that will benefit are located within EPA's Inflation Reduction Act (IRA) disadvantaged communities. The award will enable IEPA to purchase new dataloggers, portable and semi-portable zero air generators, sulfur dioxide, carbon monoxide and nitrogen oxide monitors, ozone transfer standards, and dilution systems. This equipment upgrade will increase the sustainability of IEPA's ambient air monitoring network and directly benefit the residents of disadvantaged communities across Illinois.
