Illinois Ambient Air Monitoring Network Plan for 2012

Federal Regulation 40 CFR Part 58 Subpart B 58.10 requires Illinois to submit to USEPA an annual air monitoring network plan each calendar year. The plan details the monitoring network for the criteria pollutants: carbon monoxide (CO), nitrogen dioxide (NO 2), sulfur dioxide (SO 2), ozone (O 3), particulate matter (PM 10 and PM 2.5), and lead (Pb). The network plan includes the following categories of monitoring sites: NCore (national trend sites), SLAMS (state and local air monitoring sites), SPM (special purpose monitors), PM2.5 speciation sites (trend and State), and PAMS (photochemical assessment monitoring sites). Specific site information includes locational information (address and latitude/longitude), site type, objectives, spatial scale, sampling schedule, and equipment used. In addition, changes from the previous network plan are listed.
