To improve access to highly sought Agency records, the Illinois EPA is making certain documents available for viewing and downloading in PDF format, to the extent the Illinois EPA has imaged these documents and they are available in digital format. These include:
  • Air permits (construction and operating)
  • National Pollution Discharge Elimination System (NPDES) water discharge permits
  • Leaking Underground Storage Tank (LUST) technical documents
  • Site Remediation Program (SRP) technical documents
  • State Response Action technical documents
  • Final Compliance Commitment Agreements since January 1, 2014
Some of the records listed above are maintained by the Illinois EPA in paper and/or microfilm. If you cannot find the records you are seeking, you may submit a Freedom of Information Act (FOIA) request to determine whether paper and/or microfilm records are available. To locate records within Document Explorer, search for the location of interest and select the site to access available digital records.
