The Remediation and Redevelopment (RR) Program reminds anyone submitting a case closure request that the most up to date Case Closure Request Form (4400-202) must be used per Wis. Admin. Code § NR 726.09(1). This form was last updated in October 2022 to clarify database fees and provide information on electronic submittals.

The current form can be found online, or by visiting dnr.wi.gov, search “4400-202.” Please avoid using any desktop versions that you may have saved. A case closure request may be considered incomplete if submitted on an obsolete form.

The Wisconsin Department of Natural Resources suspended the requirement to submit a paper copy of the closure request form and supporting documentation. Customers are strongly encouraged to submit documents via the online Submittal Portal. Please refer to Guidance for Submitting Documents (RR-690) for additional information on the format and procedures for submitting documents to the RR Program.
