Which department is NOT involved in the enforcement of Michigan Mechanical Law?

The Michigan Department of Natural Resources is primarily focused on the management and conservation of Michigan's natural resources, which include wildlife, forests, and recreational areas. While its responsibilities are crucial for the preservation of the environment and natural habitats, they do not directly relate to mechanical law enforcement, which governs the standards and safety of mechanical systems and equipment.

On the other hand, the Michigan Department of Licensing and Regulatory Affairs is directly involved in establishing and enforcing regulations related to mechanical systems, including licensing and inspections. Similarly, the Michigan Department of Health and Human Services would be concerned with health aspects that may relate to mechanical systems, particularly as they pertain to safety standards. The Michigan Department of Environment, Great Lakes, and Energy is responsible for environmental regulations that could overlap with mechanical law in aspects such as emissions and waste management from mechanical systems.

Thus, the Michigan Department of Natural Resources' mission and functions do not encompass the enforcement of mechanical law, making it the correct choice in this context.
