Who regulates the disposal of waste in Wisconsin?

The correct response is the Wisconsin Department of Natural Resources (DNR) because this agency is responsible for managing the state's natural resources, including the regulation of waste disposal. The DNR oversees various aspects of environmental protection, including waste management practices to ensure they comply with both state and federal regulations. This includes guidelines and enforcement related to hazardous waste, landfill operations, recycling, and the overall environmental quality in Wisconsin.

The U.S. Environmental Protection Agency (EPA) does play a role in regulating waste at the federal level; however, it sets national standards that states like Wisconsin must follow, but it does not directly manage waste disposal within the state. The Wisconsin Department of Health primarily focuses on health concerns rather than environmental regulations. The Wisconsin Department of Labor deals with workplace safety and employment standards, which do not include waste management. Hence, the primary responsibility for waste regulation rests with the DNR in Wisconsin, making it the appropriate answer.
