Abstract
This report presents a summary of air quality data collected throughout the State of Illinois during the calendar year - 1999. Data is presented for the six criteria pollutants (those for which air quality standards have been developed - particulate matter (PM10 and PM2.5), ozone, sulfur dioxide, nitrogen dioxide, carbon monoxide, and lead) along with some heavy metals, nitrates, sulfates, and volatile organic compounds. Monitoring was conducted at over 100 different site locations collecting data from more than 200 instruments. In terms of the Pollutant Standards Index (PSI) air quality during 1999 was either good or moderate more than 99% of the time throughout Illinois. There were four days Statewide which exceeded an air quality standard for any pollutant all four for ozone. These exceedances occurred in Jersey (3), and Madison (1) Counties (ozone). Air quality trends for the criteria pollutants are continuing to show downward trends or stable trends well below the level of the standards. In 1999 monitoring was initiated for PM2.5 using Federal Reference Method (FRM) monitors at 25 locations Statewide as the first phase of fine particulate (less than 2.5 microns) sampling. The rest of this network will be implemented in 2000. Stationary point source emission data has again been included. The data in the report reflects information contained in the Emission Inventory System (EIS) as of December 31, 1999. Emission estimates are for the calendar year 1999 and are for the pollutants: particulate matter, volatile organic material, sulfur dioxide, nitrogen oxides and carbon monoxide. Emission trends of these pollutants has been given for the years 1981 to the present. Emissions reported with the Annual Emissions Report have been provided starting with 1992. In general there has been a trend toward decreasing emissions over this time period.
