<br />b. Location of septic tanks shall be subject to the following <br />restrictions: 10 feet from any building intended for human <br />occupancy; 10 feet from a lot line; 50 feet from a well or <br />other water supply; and where feasible, the septic tank shall <br />be placed downslope from a well. <br /> <br />3.36 Soil Abosorption Systems <br /> <br />a. Placement of soil absorption systems shall be in accordance <br />with the shore land management classification of the applicable <br />public water body and shall be subject to the following <br />specifications, where soil conditions are adequate: <br /> <br />1. On Natural Environment Lakes and Streams, at least <br />150 feet from the ordinary high water mark. <br /> <br />2. On Recreational Development Lakes and Streams, at least <br />75 feet from the ordinary high water mark. <br /> <br />3. On General Development Lakes Streams, at least 50 feet <br />from the ordinary high water mark. <br /> <br />b. In addition, placement of soil absorption systems shall be <br />subject to the following specifications: 10 feet from a lot linej <br />20 feet from a building intended for human occupancy; and 50 <br />feet fromciwell.or other water supply source. <br /> <br />c. Minimum seepage area of the disposal field (total flat area) <br />of trench bottom exclusive of sidewall area) shall be determined <br />by the following percolation test procedure as applied to Table 1. <br /> <br />1. Number and location of tests. Two or mbre tests shall <br />be made in spearate test holes spaced uniformly over the <br />proposed absorption field site. <br /> <br />2. Type of test hole. A 'hole with horizontal dimensions <br />of 4 to 12 inches and vertical sides shall be dug or bored <br />with an auger of not less than 4-inch diameter. <br /> <br />3. Preparation of test hole. The bottom and sides of the <br />hole shall carefully scratched with a knife blade or sharp <br />pointed instrument to remove any smeared soil surfaces and <br />to provide a natural soil interface into which water may <br />percolate. All loose material shall be removed from the <br />hole and 2 inches of coarse sand or fine gravel shall be <br />added to protect the bottom from scouring. <br /> <br />4. Saturation and swelling of the soil. The hole shall be <br />carefully filled with clear water to minimum depth of 12 <br />inches over the gravel. Water shall be -kept in the hole <br />for at least 4 hours, and preferabley overnight, by refillin[ <br />if necessary, or by supplying a surplus reservoir of water, <br />such as in an automatic siphon. <br /> <br />13. <br />
