Wisconsin Administrative Code (Wis. Admin. Code) § NR 700.11(1)(a) requires responsible parties (RPs) to submit semi-annual site progress reports to the
Wisconsin Department of Natural Resources (DNR) until case closure is granted by the DNR. The reports summarize the completed work and additional work
planned to adequately complete the response action at the site or facility. Consultants may submit these reports on behalf of RPs.
For more information, see the guidance for NR 700 semi-annual reporting.
