Which agency is typically responsible for handling spill reports in Wisconsin?

The Wisconsin Department of Natural Resources (DNR) is the agency primarily responsible for managing environmental concerns, including handling spill reports. This agency oversees the protection and management of Wisconsin's natural resources, which encompasses water quality and pollution control. In the event of a hazardous spill, the DNR works to assess the situation, coordinate cleanup efforts, and ensure that environmental regulations are followed to mitigate any adverse effects on the ecosystem and public health.

The other options, while they may have roles in related areas, do not have the primary responsibility for managing spill reports in the same capacity as the DNR. The Department of Agriculture might handle agricultural spills but is less comprehensive when it comes to environmental spills broadly. The National Guard typically responds to emergencies and disasters but is not specialized in environmental management, while local municipal governments may address smaller incidents but lack the statewide jurisdiction and resources of the DNR for larger or more significant spills.
