Dear Ms. Newton: 

Enclosed you will please find two reports and a CD which provides the Illinois Environmental 

Protection Agency's 2002 base year emissions inventories for 8-hour ozone and PM2.5 as 

required by Section 172( c )(3) ofthe Clean Air Act. These reports meet the requirements to 

submit an emissions inventory for ozone nonattainment areas for the 2002 base year by June 15, 

2006. 

The report entitled "Illinois BaseY ear Ozone Inventory for 2002" is the inventory for ozone 

precursors, namely carbon monoxide, nitrogen oxides and volatile organic material. The format 

of this report is similar to previous periodic inventories submitted by Illinois EPA under the !-

hour ozone standard. Summaries are provided for each precursor for each ozone nonattainment 

area (Chicago and Metro-East St. Louis), and for all of the other counties statewide as well. The 

Illinois EPA is planning a public hearing in the near future to solicit comments on this inventory 

from Illinois stakeholders. Depending on the nature of the comments we receive, we may need 

to supplement the information provided in this submittal. 

The report entitled "Illinois Base Year Particulate Matter Inventory and Haze for 2002" is the 

particulate matter inventory. Illinois EPA recognizes this report is not due at this time, but since 

much of the information and source categories in this report are similar to the ozone inventory, 

Illinois EPA decided to compile and submit both inventories at the same time. Similar to the 

ozone report rnentioned above, summaries arc provided for each particulate matter nonattaimnent 

area (Chicago and Metro-East St. Louis) and for all remaining counties in Illinois as well. Since 

this report is not yet due, please consider this report to be a draft for your review and comment. 

The Illinois EPA will finalize this report in the future pending final guidance from U.S. EPA and 

comments received from Illinois stakeholders. 

The enclosed CD contains the Adobe Acrobat versions of the reports. The CD also contains four 

Access databases (point, area, on-road mobile and off-road mobile) in NEI format. This data is 

provided to give access to the entire data set used to compile the reports. Some additional 

reports have been included in these databases (e.g., point source emissions by source) since the 

magnitude of the data precludes printing the information.
