Illinois Surface Discharge Permit (ILG62)

The ILG62 General Permit expired February 9, 2019.  These discharges in the state of Illinois will now be handled by Illinois EPA.  For more information please contact Amy Dragovich, Manager of the Permits Section for IEPA’s Division of Water Pollution Control, at (217) 782-0610, or at

EPA’s Illinois Discharge Permit (ILG62) for new and replacement surface discharging systems in Illinois became effective on February 10, 2014. The permit authorizes a discharge of pollutants from new and replacement surface discharging systems to waters of the United States, not the actual systems themselves. 

People who are eligible for the final general permit will be able to discharge pollutants from septic systems to waters of the United States in accordance with the terms and conditions of the general permit. The permit sets discharge limits and requires periodic inspection, monitoring and reporting. Anyone not eligible for the General Permit may apply to the Illinois Environmental Protection Agency for an individual NPDES permit. 

How do I get coverage under the general permit?

Complete the following documents:

Submit the documents by email ( or by mail to:

Chicago, IL 60604-3590 

How will I know if I am covered under the general permit?

EPA will review the NOI and other documents and will make a decision 30 calendar days from the date it is received. Unless coverage is denied, you are eligible to discharge in accordance with the General Permit 30 calendar days after EPA receives your NOI. EPA will send a coverage letter to you and the applicable county health department. If you are denied coverage, EPA will notify you and the applicable county health department of the decision by phone and will follow up with a formal decision letter.

Aren't there new electronic reporting requirements?
