When a single SSTS or group of SSTS under single ownership within one-half (1/2) mile of each other have a design flow greater than ten thousand (10,000) gallons per day, the owner or owners shall make application for and obtain a state disposal system permit from the MPCA in accordance with Minnesota rules chapter 7001. If the measured daily flows for a consecutive seven (7) day period exceed ten thousand (10,000) gallons per day, a state disposal system permit is required. (Minnesota rules 7081.0040, subpart 1(B))
A state disposal system permit is also required for any SSTS or group of SSTS that the commissioner determines has the potential or an increased potential to cause adverse public health or environmental impacts if not regulated under a state permit. Conditions for these permits include systems in environmentally sensitive areas, unsubstantiated or unexpected flow volumes, and systems requiring exceptional operation, monitoring, and management. (Minnesota rules 7081.0040, subpart 1(C)) (Ord. 1219, 10-25-2010)
