, . � . . , , Rusty Olson's--Soil and Percolation Testing Joseph J. Olson--MPCA License#810 11481 Riverview Rd. NE, Hanover,MN 55341 (612) 498-8779 November 13, 1998 Rick Vogelgesang 4700 Creekwood Trail Orono,Henn.Co. This On-Site Sewage Treatment System is Designed for a Type 1, five bedroom home in accordance with the Minnesota Pollution Control Agency Chapter 7080 and local ordinances. The soils on this site are SCS soils mapped - HA Hamel Loam. The seasonally saturated soils were located at 18"- 2Y'(mottled soil). Due to the seasonally saturated soils, a pressurized mound system will need to be installed to treat septic ef'fluent. The bottom of the treatment$rea must be located at teast 3' above the saturated soils. The soils at a depth of 12"have a percolation rate averaging 4.0 MPI. All neighboring wells are located greater than 100' away from the proposed treatment area. A pumping chamber witl necd to be installed to lift the effluent to the treatment area. The power suppiy and switches must be located outside the manhole and pumping chamber in a weather proof enclosure. A warning device must be installed with light and sound device,this is in case of a pump failure. The maniiold and supply line pipe must have back drainage to the pumping chamber. The distribution pipes shall have their ends capped. Be sure the rock and sand fili materials are clean. The sod layer below the entire mounded area must be turned over,just break up the sod,be sure not to over work. Keep all heavy equipment off of the proposed treatment areas before and after construction. The treatment area should be marked off before construction. This Design is not valid & the System will need to be relocated if failure to protect the areas proposed for On-Site Sewage Treatment oCcurs. Nothing other than gray water,(laundry,showers,etc.)human waste& toilet tissue should be disposed of into the septic tanks. Garbage disposals are not recommended. Additives must not be used, they may cause harmful damage to your septic system. It is recommended that you pump the tank every year for 1 tank every two years for two tanks. Sincerely, Joseph J.
