Olson—MICA License#810 <br /> 11481 Riverview Rd.NE,Hanover,MN 55341 <br /> (763)498-8779 Fax(763)498-8290 <br /> August 17,2003 U 2-4 lb- 62 Z(o <br /> Randy Westrand o S <br /> 525 Orchard Park oad LO J l <br /> COrono,Henn.Co. / <br /> This on-site SewageTreatmentSystem is designed for a Type 1,three bedroom home in accordance with the <br /> Minnesota Pollution Control Agency Chapter 7080 and local ordinances. <br /> The seasonally saturated soils were located at 20"-32"(mottled soil). Due to seasonally saturated soils,a <br /> pressurized Mound System will need to be installed to treat septic effluent. The bottom of the treatment area must be <br /> located at least 3'above the saturated soils. <br /> The soils at a depth of 12"have a percolation rate averaging 7 MPI. <br /> All neighboring wells are located greater than 100' away from proposed treatment area. <br /> A variance will be needed to be closer than 75 feet from the wetland fringe. <br /> The existing tanks may be used upon approval of local inspector. <br /> The existing system does not conform to chapter 7080. <br /> A pumping chamber will need to be installed to lift the effluent to the treatment area. The power supply and <br /> switches must be located outside the manhole and pumping chamber in a weatherproof enclosure. A warning device <br /> must be installed with light and sound devices;this is in case of a pump failure. <br /> The manifold and supply line must have back drainage to the pumping chamber. The distribution pipes shall have <br /> their ends capped. Be sure the rock and sand fill materials are clean. The sod layer below the entire mounded area <br /> must be turned over,just break up the sod and be sure not to over work. <br /> Keep all heavy equipment off of the proposed treatment area before during and after construction. This <br /> Design is not valid and the System will need to be relocated if failure to protect the area proposed for On-Site <br /> Sewage Treatment occurs. <br /> With proper installation and maintenance,this system should have no problem in treating septic effluent effectively. <br /> Nothing other than gray water,(laundry,showers,etc.) Human water and toilet tissue should be disposed of into the <br /> septic tanks. Garbage disposals are not recommended. Additives must not be used;they may cause harmful damage <br /> to your septic system. It is recommended that you pump the tank every year for 1 tank every two years for two tanks. <br /> S..cerely, Miff" <br /> Oltelie <br /> �r .: t <br /> • 4 411'AII r' 420' <br /> Joseph J.Olson ' x • q4i <br /> i.74. rosters*mitineratit" <br /> APPIOVED WITS~TIMIS HI 1011110 <br /> as MDT AfTSOtl R IUMNAIMIT <br /> LSI +� ossirmwrawOwywtimibravika AI wit IAA*** <br /> 6 Nil wompilmwe oak wA apptiodb wail mhos fob.MNQOM$. lMIV*MAW IN tment Ilimakenestsadadieg IkonMill swifts*wad Is*hwk" <br /> INUMMES NIS OESIGN.
