All work shall be done <br /> Orono, Henn. Co., MN full peatsa with all applicable septic and zoning code. <br /> Requirements including items not specally noted in this review. <br /> KEEP THIS PLAN SET ON SITE AT ALL TIMES <br /> This site has an existing system which is classified as failed due to not meeting the <br /> required separation from the bottom of the system and the mottled soil (redox features). <br /> The upgrade date is 2010 if the system is not an imminent health hazard. <br /> On 3-28-03 the system was surface discharging which is classified as an imminent <br /> health hazard which requires the system to be upgraded within 10 months. I opened <br /> the inspection pipe on the 1st tank and water was flowing continuously for 1 hour. It <br /> was determined that the iron filter in the house was discharging continuously. This was <br /> repaired and on 4-14-03 no surface discharging was found. The proposal is to divert <br /> the iron filter out of the system. If surface discharging does not re-occur, the system <br /> may be used until 2010 or until it becomes an imminent health hazard. <br /> This on-site sewage treatment system is designed for a Type 1, five bedroom home, in <br /> accordance with the Minnesota Pollution Control Agency Chapter 7080 and local <br /> ordinances. <br /> The soils on this site are a clay loam. The seasonally saturated soils were located at <br /> 12" & 14" (mottled soil). Due to the seasonally saturated soils, a Pressurized Mound <br /> System will need to be installed to treat septic effluent. The bottom of the rock must be <br /> located at least 3' above the saturated soils. <br /> The soils at a depth of 12" have a percolation rate of 12.6 mpi. <br /> 1 <br />
