Applications for septic system permits may be mailed or submitted in person at the City Offices; however, permits will not be mailed out. The permit must be picked up in person at the City Offices and work must not begin unless the permit card is on the job site. 2. Permits will be issued only to contractors holding a Minnesota Pollution Control Agency(MPCA) Septic System Installers License. 3. All work must be done in accordance with the approved septic system design. Design reports are not considered approved unless accompanied by the "City of Orono Septic System Approval" cover sheet signed by the City Inspector. 4. The following inspections will be required for all septic systems: A. Pre-installation site inspection to include inspector, installer, and general contractor. B. Tank installation prior to covering. C. Drainfield trench installation prior to covering. For mounds, inspection is required after rough up but prior to sand placement (sand will be jar tested for silt content), and again during pressure distribution piping installation in the rock bed. D. Final inspection to verify proper final cover depths and to verify that all pump stations (where required) components are functional and comply with codes. ti. Individual holding MPCAInstallers License shall be present during all inspections. A 24-hour notice is required for all inspections. NOTE: Applicant must initial all spaces.

L., Lei&e This on-site Sewage Treatment System is designed Tor a Type 1 three-bedroom home in accordance wi (-' the Minnesota Pollution Control Agency Chapter 7080 and local ordinances. The soils on this site are SCS. soils mapped-KkB-Kilkenny loam.The seasonal saturated soils were located at 12"-16"(mottled soil).Due to the seasonally saturated soils,a pressurized mound system will need to be installed to treat the septic effluent.the bottom of the treatment area must be located at least 3' above the saturated soils. All neighboring wells are greater than 100'from proposed treatment areas. The soils at a depth of 12"have a percolation rate averaging 3 MPI. The existing tanks must be abandoned. The absorption area of the mound is 24'from the property line and 65'from the wet land. A pumping chamber will need to be installed to lift the effluent to the treatment area. The power supply and switches must be located outside the manhole and pumping chamber in a weatherproof enclosure. A warning device must be installed with light and sound devices;this is in case of a pump failure. The manifold and supply line must have back drainage to the pump chamber. The rock and fill materials must be clean.The sod layer below the entire mounded area must be turned over. Just break up the sod and be sure not to over work. Nothing other than gray water,(laundry.showers,etc.) Human water and toilet tissue should be disposed of into the septic tanks. Garbage disposals are not recommended. Additives must not be used;they may cause harmful damage to your septic system. It is recommended that you pump the tank every year for 1 tank every two years for two tanks. Sincerely • 4 Joseph J.
