Schirmers • MPCA Cert.No. 627 <br />951 Katydid Lane NE• St. Michael, MN 55376 • (763) 497-3566 <br />FAX(763)497-5011 <br />State License #394 <br />October 15, 2004 <br />Rick Palm <br />Lot 4, Kitchel's Sub-division <br />Henderson Property <br />Big Island, Orono, MN <br />A site evaluation was completed for on-site sewage treatment systems for this property. <br />Four soil borings were completed which found mottled soil (redox features) at 24" <br />below the ground surface. A pressurized mound system would be needed to treat <br />septic effluent. A mound system for a Type 11, three bedroom cabin (300 gal/day) <br />would require an area of 40' x 60'. The site plan shows two areas using a 20' setback <br />from the property lines & 20' setback to the structure. This leaves very limited space <br />for a structure & is on 18% slope. Even using a 1 0' setback from the properly line limits <br />the house location. <br />An option would be a Performance system under Minnesota Chapter 7080.0179 rules <br />using a pressurized seepage bed with less separation to the redox features using <br />pretreatment with positive filtration and an alarm. <br />¼-B.~ <br />Steven B_ Schirmers <br />1 <br />14102
