i. Septic system permit fees--Fargo Cass Public Health

"Dosing Device" - or pump pit, siphon, or other device that discharges sewage tank effluent from the dosing chamber to the soil treatment system. "Drain Field" - is also called the tile disposal field or soil absorption field and uses distribution pipes placed in favorable soil so that sewage from the septic tank can percolate through and into the soil. "Dwelling" - is any building or place used or intended to be used by human occupants as a single-family or two-family unit. "Filter Material" - is clean, rock, crushed igneous rock or similar insoluble, durable, and decay-resistant material free from sand, silt, or clay. The size shall range from three-fourths (3/4) inch minimum diameter to one and one-half (1 Y:.) inches effective diameter. "Floodway" - the channel of a river, a stream, and those parts of the flood plain and adjoining the channel which are reasonably required to carry and discharge the flood water, a flood flow of the river or stream. "Gray Water" - liquid waste from a dwelling or other establishment produce by bathing, laundry, floor drains, other than toilet wastes. "Holding Tank" - is a water-tight tank for storage of sewage until it can be transported to a point of approved disposal. "Impermeable" - with regard to soils, is a soil horizon or layer having a vertical permeability less than one (1) inch in twenty-four (24) hours and shall be considered impermeable. "Individual Sewage Treatment System" - is a sewage treatment system or part thereof, serving a dwelling or other small living or business unit, or group thereof, which utilizes subsurface soil treatment and disposal. "Lawn Area" - is the area bounded by the dimensions required for the proper location of the soil treatment area. "Malfunctioning System" - any component or components of an existing or new septic system which fails and thereby causes overland flow, noxious odors, or public nuisance. "Mound System" - is a system where the soil treatment area is built above ground to overcome limits imposed by proximity to water table or bedrock, or by rapidly or slowly permeable soils. "Percolation Rate" - is the time rate of drop of water surface in a test hole. "Permeability" - the case with which gases or liquids penetrate or pass through a bulk mass of soil or layer of soil. "Plastic Limit" - is soil moisture content below which the soil may be manipulated for purposes of installing a soil treatment system and above which manipulation will cause compaction and puddling. If a fragment of soil can easily be rolled into a wire one-eighth (1/8) inch diameter, the moisture content is below the limit and the soil may be manipulated. The standard method of determining the plastic limit is specified by the American Association of State Highway Officials (AASHO) Designation: #T 90-61. 5
