Minnesota Rules: Chapters 7080-7083
There are four layers of regulations. The federal government has regulations, the Minnesota legislature writes local statutes, the MPCA writes Chapter 7080, and local governmental units (i.e. counties, townships and cities) have local ordinances. Therefore, the requirements vary across the state.
