,:P TESTING, INC. Steven B. Schirmers — MPCA Cert. No. 627 <br /> • 951 Katydid Lane NE • St. Michael, MN 55376 • (612) 497-3566 <br /> September 18 , 1995 <br /> Greg Kellenberger <br /> 4045 Watertown Rd. Th <br /> Orono, Henn. Co. , MN1. cr <br /> • <br /> This site has an existing Non-Conforming On-Site Sewage Treatment <br /> System which was not found but the soils are mottled (seasonally <br /> saturated) less than 3 ' below the ground surface in all possible <br /> areas for a system. When the house is reconstucted, follow the <br /> supply line from the home to the existing tank or tanks & abandon, <br /> pump & fill with soil . <br /> This On-Site Sewage Treatment System is Designed for a Type 1, four <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. A seasonally high water <br /> table (mottled soil) was found at 14" to 22" below the ground <br /> surface. Due to the seasonally high water table, a Pressurized <br /> Mound System will need to be installed to treat septic effluent. <br /> The proposed sites are on approximately 6% to 8% slope & will need <br /> approval from the city Inspector for over 6% . This is the only <br /> area available for an On-Site Sewage Treatment System which is <br /> undisturbed or has mottled soil greater tahn 1.2" below the ground <br /> surface. <br /> The soils at a depth of 12" have a percolation rate averaging <br /> 5.4 min/inch. <br /> A pumping chamber will need to be installed to lift the effluent <br /> to the treatment area. <br /> The manifold and supply line pipe must have back drainage to the <br /> pumping chamber . The distribution pipes shall have their ends <br /> capped. Be sure the rock and sand fill material are clean. The <br /> sod layer below the entire mounded area must be turned over, just <br /> break up the sod, be sure not to over work. <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 /> CONT' D <br />
