The following is a list of minimum standards applicable to SSTS.
(A) In no land use district shall a land use permit, shoreline alteration permit, minor subdivision, plat, conditional use permit, or variance be issued without a current certificate of compliance or certificate of installation that has not expired according to § 151.20(C).
(B) At least one cleanout at or above finished grade shall be installed between the structure and the septic tank with additional cleanouts at intervals not more than 100 feet.
(C) Class I sizing is required on all new construction. NEW CONSTRUCTION will be defined as placement of a new structure or replacement structure that is served by pressurized water.
(D) Minimum septic tank sizing shall be 1,500 gallons. This can be accomplished through a compartmentalized tank, multiple tanks in series, or a single existing 1,500 gallon tank with the use of an effluent filter for the last baffle. The filter must be of such a design that when the filter is removed from the filter housing, the flow of water leaving the tank is not allowed. The first tank or compartment shall be not less than 1,000 gallons in size and applies to new and replacement SSTS. Any additional septic tanks shall be a minimum of 1,000 gallons. All other tank sizing shall follow Minn. Rules part 7080.1930, as amended from time to time.
(E) Pump tank sizing shall follow Minn. Rules part 7080.2100, as amended from time to time.
(F) Soil pits shall be required during the construction inspection. The soil pit shall be excavated at the time of the inspection. The soil pit shall be dug by a backhoe or other acceptable method and be excavated to a depth that will allow the verification of redoximorphic features and the three feet of vertical separation as required. Location of soil pits shall be adjacent to the lowest trench or next to the down slope side of an elevated treatment area. The pit shall not impact the hydraulic performance of the ISTS. A certificate of installation will not be issued until the soils are verified.
(G) All dwellings or buildings that contain plumbing fixtures shall meet the required setbacks to the septic tank and soil absorption area. Accessory structures, including, but not limited to, decks, screen decks, porches, sheds, garages, and pole buildings shall not be required to meet said setbacks, provided that the tank(s) can be maintained properly and that the structure does not negatively impact the function of the system.
