Lyon County Planning & Zoning administers Minnesota Rules Chapters 7080-7083 through their local Subsurface Sewage Treatment System (SSTS) ordinance; issuing permits for systems designed with flows up to 10,000 gallons per day. 

In Lyon County, inspections are required for all new septic system construction and replacement. Lyon County ordinances also state that septic systems must be in compliance with Minnesota Rules Chapter 7080-7083 at the time of a property transfer. Existing systems must also be inspected when there is a bedroom addition on a building permit, or when any building permit or variance is requested for systems located in a shoreland area.

Lyon County currently offers low-interest loans for qualifying residents seeking to upgrade an existing system. Loan dollars are offered through local watershed districts, and are applied to property taxes as a special assessment. The length of the loan can be up to 10 years at a rate of interest of 4%.
