Who to ask about permits.
- North Dakota: installers are licensed by the Department of Environmental Quality and must get a permit from the local public health unit before working on a system.
- Minnesota: SSTS work is licensed by the MPCA, and counties run permits and, in many counties, inspections at sale.
- South Dakota: DANR administers the on-site wastewater rules (ARSD 74:53:01); counties may add more.
