two ozone non-attainment areas.
1. Maintenance of attainment status for
pollutants other than ozone and PM2.5,
especially in urban areas.
Ozone and PM2.5:
2. Attainment of the 8-hour ozone standard
by 2010.
3. Attainment of the PM2.5 standards by
2010.
Trends in monitored levels of each criteria
pollutant other than ozone.
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.
Program Objectives
1. For the Chicago ozone non-attainment
area, 2006 and 2007 total ozone season
weekday VOM emissions will be at or
below 750 tpd.
2. For the Metro-East ozone maintenance
area, 2006 and 2007 total ozone season
weekday NOx emissions will be at or
below 1560 tpd.
3. Reductions in emissions of hazardous
air pollutants.
4. Minimize the number of days of
violation at high priority sources.
Program Outcome/Measures
Seasonal VOM emissions in the Chicago area
ozone non-attainment area by sector.
Seasonal NOx emissions outside the Chicago
ozone non-attainment 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 daily 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. Attaining the 8-hour ozone and PM2.5 air quality standards in the Lake Michigan
region is a priority with Illinois EPA. 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
