The following table contains electronic copies of all currently effective site-specific wastewater permits — not master general permits — issued by the department. These facilities have been authorized to either discharge to waters of the state, or to operate a no-discharge wastewater treatment facility. These permits are written to be site-specific, issued to that one location to reflect the unique nature of the wastewater or the receiving water. The list includes Concentrated Animal Feeding Operation (CAFO) permits, stormwater permits, wastewater permits and underground injection control well permits. The permits are consistent with applicable water quality standards, effluent standards or treatment requirements or suitable timetables to meet these requirements (10 CSR 20-7.015 and 7.031).

The department will add each site specific wastewater permit as it is issued. If you cannot find the information you are looking for, please submit an Open Records/ Sunshine Law Request.
