Remediation & Redevelopment (RR) Program staff contacts

The DNR's Remediation and Redevelopment (RR) Program oversees the investigation and cleanup of environmental contamination and the redevelopment of contaminated properties. Our staff provides a comprehensive, streamlined program that consolidates state and federal cleanups into one program (e.g., hazardous waste cleanup; underground storage tank investigation and cleanup; spill response; state-funded cleanups and brownfields).

The following lists can help you get in touch with the right RR staff person for your needs.
