WPDES Permits on Public Notice
Public notices are required by law to alert interested members of the public of the DNR's intention to authorize a Wisconsin Pollutant Discharge Elimination System (WPDES) discharge to a water of the state. The notices are posted here on the DNR website for 30 days and are also published once in the legal notices section of the local newspaper in the vicinity of the facility. The notice identifies the facility by name, indicates where the discharge is located and briefly describes the facility's activities.
Public comments procedure
The public notice document explains how to get more information or comment on the proposed permit action. A member of the public may submit written comments or request that the department hold a public informational hearing. For comments or requests to be timely, they must be submitted within 30 days from the date of public notice, unless otherwise indicated in the notice.
Public participation procedures are detailed in NR 203, Wis. Adm. Code [PDF exit DNR].
Permit issuance process
The process the DNR follows in issuing WPDES wastewater permits is explained in the overview of the WPDES wastewater permit process. Permits are not considered final and issued until they have been signed and dated by appropriate DNR staff. Final copies of WPDES wastewater permits are not available from the DNR website. Please contact the permit drafter indicated in the notice directly to obtain a copy of a final (issued) permit. Copies of permit applications can also be obtained by contacting the permit drafter.
