National Pollutant Discharge Elimination System (NPDES) General Permit Information
The United States Environmental Protection Agency (USEPA) issued NPDES General Permit No. ILG62 for point source discharges of pollutants from new or replacement individual private sewage disposal systems into the Waters of the United States. The permit took effect on February 10, 2014. No new or replacement surface discharging individual wastewater treatment and disposal system may be constructed without coverage under this permit if the system discharges to the Waters of the United States.
It is the responsibility of the potential discharger, which in most cases is the property owner, to determine whether or not his or her system might discharge to a water of the United States. In some situations, making this determination may be difficult. EPA suggests a common-sense way of evaluating whether you are required to be covered by an NPDES General Permit: If you were to install or replace a surface discharging system on your land, would effluent or pollutants (even diluted ones) from your system end up in the water of the United States or a conveyance – such as a ditch, drainage pipe, channel, tunnel, conduit, discrete fissure, or other means – that leads to a water of the United States? In evaluating this question, consider that rainwater, irrigation activities, lawn sprinkling systems, and any other ways that water can carry pollutants to waters of the United States.
For those surface discharging private sewage disposal systems from which effluent enters into the Waters of the United States that require a general NPDES permit, a permit can be obtained from the US Environmental Protection Agency (USEPA) or the Illinois Environmental Protection Agency (IEPA).
