General NPDES Permit Numbers ILG551, ILG580 and ILG582 were issued for the discharge of domestic wastewaters generated by existing lagoon wastewater facilities. In order for facilities to obtain coverage under a general permit, a discharger must submit a permit application.
The permit application will be reviewed by the Illinois EPA, and if the Agency determines that the facility may be covered by a general NPDES permit, a notification will be posted on the Illinois EPA’s webpage for a period of 14 days. Coverage under the general NPDES permit(s) will be by letter issued by the Illinois EPA.
