A review of Indiana's Ambient Air Monitoring Network is to be conducted as per 40 CFR Part 58 Subpart B 58.10. The review is to assess the current air monitoring network and determine if any changes are necessary to meet the monitoring goals and monitoring projects across the state. All criteria pollutant monitoring networks, carbon monoxide, lead, nitrogen dioxide, ozone, PM10, PM2.5, and sulfur dioxide, are evaluated. Other networks such as toxics, PM2.5 speciation, PAMS, metals, and meteorology are evaluated as well. Any network modifications become part of the 2021 Network Plan.
