Wastewater Permit Process Improvements Study Group

The Wastewater Permit Process Improvements (WPPI) Study Group is a stakeholder group formed in 2017 by the DNR Wastewater Program. The group serves as an opportunity for the program to receive input from and provide information to stakeholder organizations. The goal of the study group is to provide the Wastewater Program with constructive feedback on policy and technical issues and to work collaboratively with DNR staff to find workable solutions that may be used to improve the process for Wisconsin Pollutant Discharge Elimination System (WPDES) individual and general permits issued to dischargers of wastewater to surface and groundwater.

The study group identifies issues and topics of interest that can be addressed by ad hoc subgroups. Subgroup members are expected to research and develop recommendations on the selected topics for presentation to the full group.

The study group meets quarterly or semi-annually, with additional subgroup meetings scheduled as needed. Meetings are open to the public.



Study Group members are appointed by the DNR Secretary. Members represent a range of stakeholder organizations including local and federal government, industry, environmental organizations, and law firms.
