ozone non-attainment areas.
2. Maintenance of 90% "good" or "moderate" air
quality conditions in the two ozone non-attainment
Air Quality Index levels in the ozone non-attainment
3. Maintenance of attainment status for pollutants
other than ozone and PM2.5, especially in
Ozone and PM2.5:
1. Attainment of the 8-hour ozone standard by
2. Attainment of the PM2.5 standards by 2010.
Trends in monitored levels of each criteria pollutant other
Trends in the relationship between the number of days in
exceedance of the 8-hour ozone and PM2.5 standards in
the non-attainment areas and the number of days
conducive to the formation of ozone and PM2.5.
1. For the Chicago ozone non-attainment area,
2007 and 2008 total ozone season weekday
VOM emissions will be at or below 750 tpd.
2. For the Metro-East ozone nonattainment 2007
and 2008 total ozone season weekday VOM
emissions will be at or below 80 tpd.
3. Reductions in emissions of hazardous air
4. Minimize the number of days of violation at
high priority sources.
Seasonal VOM emissions in the greater Chicago ozone
nonattainment area by sector.
Seasonal VOM emissions in the Metro-East ozone
nonattainment area by sector.
Trends in hazardous air pollutants emissions as reported
through the National Toxics Inventory.
Average number of days for significant violators to
return to compliance or to enter into enforceable
compliance plans or agreements.
3. Performance Strategies - Performance strategies include the day to day activities performed
by the Bureau of Air that ensure that our environmental goal and program objectives and
outcomes are being met. The performance strategies are described below as program
activities. The program activities described below support our efforts to attain the 8-hour
ozone and PM2.5 standards.
a) Ozone and PM2.5 – Portions of Illinois are not in attainment for the 8-hour ozone and PM2.5
standards (Chicago and Metro-East St. Louis). Therefore, attaining these standards is a
priority for us, and it deserves attention separate from the other, more functional programs in
the Bureau of Air.
• General - Illinois EPA will continue and expand upon our previous progress towards
obtaining voluntary episodic emission reductions through the Partners for Clean Air,
including measurement of program support, assessment of state implementation plan (SIP)
credit potential, and continuation of our public education efforts. If sufficient funding can be
obtained, we will sponsor a “Green Pays on Green Days” educational giveaway program
during the 2008 and 2009 ozone seasons. Additionally, we will participate in ozone
forecasting and mapping projects.
• Ozone and PM2.5 Planning – Illinois EPA has submitted the 2002 and 2005 annual statewide
emission inventories of major sources, including ozone precursors in NET format. Illinois
EPA will continue to participate in multi-state efforts to develop ozone and PM2.5 modeling
analyses to support future attainment demonstration submittals.
