SP TESTI NG 1 NC. <br /> Steven 6.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.sptestin�.wastewater comcast.net— schirmerswastewater.com <br /> October 4, 2016 <br /> Tim Johnson <br /> Lynne Rasmussen <br /> Brian O'Connell <br /> 1285 French Creek Dr. <br /> Orono, MN <br /> This letter is in regard with the alternate site for an on-site sewage <br /> treatment system. The original site or the alternate site has been <br /> disturbed by the driveway & is no longer available for use. <br /> The existing system was repaired on 9-3-2002. The system was <br /> hydraulically overloaded. An additional 225 sq.ft. of trench was added <br /> along with a Type, 1 V pre-treatment unit, Multi-Flo to re-hab the <br /> system. The system is no longer hydraulically overloaded. If the <br /> system would fail in the future, the existing system would be removed <br /> to approximately 6" below the rock trenches � replace with washed <br /> sand and install a Type 111, pressurized seepage bed. The existing <br /> tanks would remain the same. This means the alternate site will be <br /> the footprint of the existing trench system. <br /> Soil probing the area north of the pond is not suitable for an on-site <br /> sewage treatment system due to fill soil, compacted soil 8� 50' <br /> wetland setback. <br /> Steven B.
