"SUORELAND" Means land located within the following distances from public waters: <br />t~l 1,000 feet fro,, the nor~.al high water mark of a lake, pond or flowage; and <br />300 feet from a river or stream or the landward extent of a flood plain <br />designated by ordinance on such a river or stream whichever is greater. <br /> <br />"SITE" The proposed on-site sewage treatment system area. <br /> <br />"SLOPE" lhe ratio of vertical rise or fall to horizontal distance. <br /> <br />"SOIL BORING" Any type of excavation capable of revealing in detail, characteristics <br />~f ~oils penetrated. <br /> <br />"SOIL CHARACTERISTICS LIMITING" Those soil characteristics which preclude the <br />~ns~-t-i-~-6f a standar~ 'system, including, but not limited to evidence of <br />seasonal high ground water table or bedrock closer than three feet to the ground <br />surface, and percolation rates faster than one-half or slower than 60 minutes <br />per inch. <br /> <br />"SOIL CLASSIFICATION" Where soil particle sizes or textures are specified in <br />~h~s regulati'on, 'th~v refer to the Guide fOr USDA Soil Textural Classification. <br /> <br />"SOIL TREATMENT AREA" An area where sewage tank effluent is treated and disposed <br />o--i~-6-6low the ground'~urface by filtration and percolation through the soil, and <br />also by evapotranspiration. Includes those systems commonly known as seepage <br />bed, trench drainfield, disposal field, and includes mounds and seepage pits. <br /> <br />"STANDARD SYSTEM" An individual sewage treatment system employing a sewage <br />tank and the soil treatment system commonly known as seepage bed or trenches, <br />drainfield or leachfield. <br /> <br />"SURFACE WATER FLOODING" The lO0-year flood plain along rivers and streams as <br />~e'fine'd by the DNR, or ~n the absence of such data, the highest flood level of <br />record. On lakes, high water levels as determined or recorded by the Department <br />of Hatural Resources or, in the case of no DMR record, by local records or <br />experie~ce. Other surface water flooding or high water areas should be determined <br />by local information. <br /> <br />"VALVE BOX" Any device which can stop sewage tank effluent from flowing to a portion <br />~f the 'so-T1 treatment area. Includes, but is not limited to caps or plugs on <br />distribution or drop box outlets, divider boards, butterfly valves, gate valves <br />or other mechanisms. <br /> <br />"WATER TABLE" The highest elevation in the soil where all voids are filled with <br />~iater', as evidenced by presence of water or soil mottling or other information. <br /> <br />4 <br /> <br /> <br />
