Restricted Status/Critical Review List
The Illinois EPA is required by 35 Illinois Administrative Code Section 306.401 of the Illinois Pollution Control Board Regulations to publish lists of sanitary districts, municipalities, and other wastewater treatment and transportation authorities which have their system or parts thereof on the restricted status list or critical review list.
In order to comply with these regulations, the Illinois EPA has prepared the following lists of facilities which are on Restricted Status or Critical Review.
Please note that these lists are continually being revised to reflect the current situation. Therefore, if you have any questions on the capability of a treatment facility or transport system, please contact this Agency for a final determination.
Restricted Status
Restricted Status is defined as the Agency determination that a sewer or lift station has reached hydraulic capacity or that a sewage treatment plant has reached design capacity, such that additional sewer connection permits may no longer be issued without causing a violation of the Act or Regulations.
