Thank you for your patience during the COVID-19 public health emergency. As state agencies continue operations, please understand that most of our staff are continuing to telework and may have limited access to files and delayed online connectivity.
Field work, including compliance inspections, is still taking place but at a limited basis. In most cases, staff will schedule pre-inspection calls with facilities to gather some of the information that would previously have been collected while on-site. These advance calls will also be used to discuss safety protocols for on-site visits that may be needed to complete all aspects of a compliance assessment.
Staff will keep their voicemails and out-of-office messages up to date and will respond as they are able.

The DNR regulates municipal and industrial operations discharging wastewater to surface water or groundwater through the Wisconsin Pollutant Discharge Elimination System (WPDES) permit program. Plans for wastewater treatment facilities must be reviewed and approved by the DNR. State law requires DNR review of municipal and industrial treatment plant construction plans as well as related monitoring systems and groundwater monitoring wells.
