SP TESTING INC. <br /> Steven B.Schirmers —951 Katydid Lane NE—St. Michael, MN 55376 <br /> Cert. No 627 — State License#394 — Phone 763-497-3566 — Fax 763-497-5011 <br /> www.sptestine.wastewater@comcast.net— schirmerswastewater.com <br /> August 9, 2018 <br /> Buddy Snow <br /> 1150 Lyman Ave. <br /> Orono. MN <br /> A Compliance inspection was completed for the existing on-site sewage <br /> treatment system located on this property for the sale of the home. The <br /> system consists of 2-1000 gallon septic tanks, 1-1000 gallon pump tank & a <br /> pressurized mound system with a 10' x 45' rock bed, built in 2000 for a 3 <br /> bedroom home. <br /> Soil boring #1 found mottled soil (redox features) at 1.8' into the original soil <br /> & the original soil at elev. 101.3 & the bottom of the rock bed at elev. 103.1 <br /> leaving 1.8' of sand below the rock bed & a 3.6' separation from the bottom <br /> of the rock & redox features. Soil boring #2 found mottled soil at 1.7' into the <br /> original soil & the original soil at elev. 101.1 & the bottom of the rock bed at <br /> elev. 102.9 leaving 1.8' of sand & a 3.5' separation. This system meets the <br /> required 3' separation from the bottom of the trenches & redox features & is <br /> classified as in compliance with Minnesota Chapter 7080 rules. <br /> A tank Integrity report has not been completed & will need to be completed <br /> for full certification. <br /> Nothing other than gray water (laundry, showers etc.) human waste & toilet <br /> tissue should be disposed of into the septic tanks. Garbage disposals are <br /> not recommended due to adding more solids & fine solids passing through <br /> into the system. Iron filters are also not recommended & should be diverted <br /> out of the system. Excessive amounts of soaps, antibacterial soaps, <br /> cleaning agents, shower cleaners used every shower & chlorine agents may <br /> kill the bacteria you need living in the system. Additives are not <br /> recommended. Recommend to pump & clean you tanks through the manhole <br /> by a certified pumper every 2 years. Check with your pumper to set up a <br /> schedule. <br /> This certificate of compliance is no guarantee that this system will continue <br /> to function indefinitely. <br /> Steven B.
