• <br /> S-P TESTING, INC. Steven B. Schirmers — MPCA Cert. No. 627 <br /> 951 Katydid Lane NE • St. Michael, MN 55376 • (612) 497-3566 <br /> May 23 , 1995 <br /> Bruce Dayton <br /> 990 Old Long Lake Rd. <br /> Orono, Henn. Co. , MN <br /> This On-Site Sewage Treatment System is Designed for a Type 1, three <br /> bedroom home Designed in accordance with the Minnesota Pollution <br /> Control Agency Chapter 7080 and local ordinances. <br /> The soils on this site are a clay loam to sandy loam. A seasonally <br /> high water table was located at 42" to 50" , (mottled soil) . The <br /> bottom of the system must be located at least 3 ' above the seasonally <br /> high water table. A Standard shallow seepage bed may be installed <br /> pressurized typical of a mound system. <br /> The soils at a depth of 12" to 18" have a percolation rate averaging <br /> 6.5 min/inch. <br /> This site has an existing Non-conforming system, less than 3 ' from <br /> the seasonally high water table. The existing tanks may be used <br /> upon approval by the local Inspector. The tanks must be water tight. <br /> The tanks will most likely need to be abandoned, pumped & filled <br /> with soil . <br /> A pumping chamber will need to be installed to lift the effluent <br /> to the treatment area. <br /> The power supply and switches must be located outside the manhole <br /> and pumping chamber in a weather proof enclosure. A warning device <br /> must be installed with a light and sound device, this is in case of <br /> a pump failure. <br /> All neighboring wells are located greater than 100 ' away from the <br /> proposed treatment area. <br /> Keep all heavy equipment off of the proposed treatment area before <br /> and after construction. The treatment area should be marked off <br /> before construction. This Design is not valid & the system will <br /> need to be relocated if failure to protect the areas proposed <br /> for On-Site Sewage Treatment occurs. <br /> CONT'D <br />
