The Wastewater Permits Database has been put online to allow the public to search DEQ's Source Information System (SIS) database for information on National Pollutant Discharge Elimination System (NPDES) and Water Pollution Control Facility (WPCF) permits.  It contains records from DEQ's Source Information System current through 3/31/2023. If you have questions about a specific facility or permit, contact your local DEQ Regional Office.

PLEASE NOTE:
These database search queries and web pages are currently under review.  Some of the queries are available, please check the list below for active links.  We apologize for the inconvenience and thank you for your patience during this review period.

Caution: The information in the SIS database may not be current or correct in all cases. Only the information in DEQ's individual permit files can be considered current and accurate.

To begin using the system click on one of the links below. Please be patient as some of the queries may take a few minutes to return results to you.
