All dwellings that are not connected to municipal or a central sewer system must be connected to an Individual Septic Treatment System (ISTS). This policy applies to all septic systems in Orono. 1: The following steps shall be completed to obtain a permit to install an ISTS in Orono: a. Obtain a complete site evaluation and a completed ISTS design from a licensed designer (include license #on the application). b. Obtain and complete an ISTS permit application from the City of Orono c. Submit a completed application for an ISTS Permit with a complete evaluation and design to the City of Orono at least three (3) business days before beginning septic work. d. The site evaluation and system design should be submitted on forms available from the U of M Extension Service SSTS Program at: http.//septic.umn.edu/formsandsheetsibytype/index.htm#design 2. Upon receiving a complete application with site evaluation and design, the City of Orono will review the documentation, visit the site to verify soils if required and issue the permit or ask for additional information. 3. Once the permit is issued, the installer must contact Metro West at least 48 hours before the requested inspection and follow up the morning of the install to confirm the time you will be ready for inspection. Please call Metro West at 763-479-1720 to schedule the inspection. If you are unable to reach Metro West, please contact Andrew Mack at the City of Orono at 952-249-4626 or at arnack( ci.orono.mn.us . 4. Upon completion of installation, the system must be inspected in accordance with MPCA rules and regulations with the Orono City Code. The inspection must be conducted before the system is fully covered without exception. The inspector will conduct an inspection and prepare an as-built report for record. 5. Upon final completion, inspection and receipt of the inspector's report, an information packet is mailed to the homeowner. This will include the original permit, the as-built compliance inspection report and information on how the homeowner can obtain good septic maintenance information. This information may be obtained from a publication produced by the U of M Extension Service Wastewater Resources website at: http://www.extension.umn.eduidistribution/naturalresources/DD6583.html#1. A printed document of this information is available for review in our City Hall Office.

NE,Hanover,MN 55341 (763)498-8779 Fax(763)498-8290 Revised February 4,2014 September 22,2011 Jeff&Paula Bata 2360 Willow Drive Orono,Hennepin County This on-site Sewage Treatment System is designed for a Type 1,Five bedroom home in accordance with the Minnesota Pollution Control Agency Chapter 7080 and local ordinances. The periodically saturated soils were located at 24-28 inches(mottled soil).Due to The periodically saturated soils,a pressurized Mound System will need to be installed to treat septic effluent.The bottom of the treatment area must be located at least 3'above the saturated soils. The soils at a depth of 12"have a percolation rate averaging 3 MPI. All neighboring wells are located greater than 100'away from proposed treatment area. A lift pump will need to be installed in the lowest level to keep the tanks 50 feet from the wetland. All tanks need to be insulated if there is less than two feet of cover over the top of the tanks.Clean outs must be installed on the end of the laterals for maintenance. 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 pumping chamber. Keep all heavy equipment off of the proposed treatment areas before,during and after construction. The area around both sites must be fenced off by the contractor before any construction begins.This Design is not valid and the System will need to be relocated if failure to protect the areas proposed for On-Site Sewage Treatment occurs. With proper installation and maintenance,this system should have no problem in treating septic effluent effectively.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 tanks every two years Sincerely, e Joseph J.Olson Vuusli uolialoamd ptrg ilus s.itosi0 Amu)] 6LL41-861,(C9L)kirl 77/-,t/-701irtl h _ ..—_—_,.__S...,....— /Air Ajr..roo er49nr+31-1"'once.) trlyra ,pinvd:c471.;i :Jo X1-1Dcloht IV smmn punwarapim un 4oato i \ .....1._ .... , VrIAI(Pull 0 : , - gavoe in P15 •-. .

Your septic system is designed to kill harmful organisms and remove pollutants before the water is recycled back into our lakes, streams and groundwater. This management plan will identify the operation and maintenance activities necessary to ensure long- term performance of your septic system. Some of these activities must be performed by you, the homeowner. Other tasks must be performed by a licensed septic maintainer or service provider. However, it is YOUR responsibility to make sure all tasks get accomplished in a timely manner. The University of Minnesota's Septic System Owner's Guide contains additional tips and recommendations designed to extend the effective life of your system and save you money over time. Proper septic system design, installation, operation and maintenance means safe and clean water!

Use the chart on page 6 to track your activities. Identify the service intervals recommended by your system designer and your local government. The tank assessment for your system will be the shortest interval of these three intervals. Your pumper/maintainer will determine if your tank needs to be pumped. System Designer: check every ° months My tank needs to be checked Local Government: check every 36 months State Requirement: check every 36 months every 24 months Seasonally or several times per year • Leaks. Check(listen, look)for leaks in toilets and dripping faucets. Repair leaks promptly. • Surfacing sewage. Regularly check for wet or spongy soil around your soil treatment area. If surfaced sewage or strong odors are not corrected by pumping the tank or fixing broken caps, call your service professional. Untreated sewage may make humans and animals sick. • Alarms. Alarms signal when there is a problem; contact your maintainer any time the alarm signals. • Lint filter. If you have a lint filter, check for lint buildup and clean when necessary. Consider adding one after washing machine. • Effluent screen. If you do not have one, consider having one added the next time the tank is cleaned. Annually • Water usage rate. A water meter can be used to monitor your average daily water use. Compare your water usage rate to the design flow of your system (listed on the next page). Contact your septic professional if your average daily flow over the course of a month exceeds 70% of the design flow for your system. • Caps. Make sure that all caps and lids are intact and in place. Inspect for damaged caps at least every fall. Fix or replace damaged caps before winter to help prevent freezing issues. • Water conditioning devices. See Page 5 for a list of devices. When possible, program the recharge frequency based on water demand (gallons) rather than time (days). Recharging too frequently may negatively impact your septic system. • Review your water usage rate. Review the Water Use Appliance chart on Page 5. Discuss any major changes with your pumper/maintainer. During each visit by a pumper/maintainer • Ask if your pumper/maintainer is licensed in Minnesota. • Make sure that your pumper/maintainer services the tank through the manhole. (NOT though a 4" or 6"diameter inspection port.) • Ask your pumper/maintainer to accomplish the tasks listed on the Professional Tasks on Page 4. - 3 - UNIVERSITY Septic System Management Plan q yi P. for Above Grade Systems OF MINNESOTA Professional Management Tasks These are the operation and maintenance activities that a pumper/maintainer performs to help ensure long-term performance of your system. Professionals should refer to the O/M Manual for detailed checklists for tanks,pumps, alarms and other components. Call 800-322-8642 for more details. • Written record provided to homeowner after each visit. Plumbing/Source of Wastewater • Review the Water Use Appliance Chart on Page 5 with homeowner. Discuss any changes in water use and the impact those changes may have on the septic system. • Review water usage rates(if available)with homeowner. Septic Tank/Pump Tanks • Manhole lid. A riser is recommended if the lid is not accessible from the ground surface. Insulate the riser cover for frost protection. • Liquid level. Check to make sure the tank is not leaking. The liquid level should be level with the bottom of the outlet pipe. (If the water level is below the bottom of the outlet pipe, the tank may not be watertight. If the water level is higher than the bottom of the outlet pipe of the tank, the effluent screen may need cleaning,or there may be ponding in the drainfield.) • Inspection pipes. Replace damaged caps. • Baffles. Check to make sure they are in place and attached, and that inlet/outlet baffles are clear of buildup or obstructions. • Effluent screen. Check to make sure it is in place; clean per manufacturer recommendation. Recommend retrofitted installation if one is not present. • Alarm. Verify that the alarm works. • Scum and sludge. Measure scum and sludge in each compartment of each septic and pump tank, pump if needed. Pump • Pump and controls. Check to make sure the pump and controls are operating correctly. • Pump vault. Check to make sure it is in place; clean per manufacturer recommendations. • Alarm. Verify that the alarm works. • Drainback. Check to make sure it is operating properly. • Event counter or run time. Check to see if there is an event counter or run time log for the pump. If there is one, calculate the water usage rate and compare to the anticipated average daily flow listed on Page 2. Soil Treatment Area • Inspection pipes. Check to make sure they are properly capped. Replace caps that are damaged. • Surfacing of effluent. Check for surfaced effluent or other signs of problems. • Lateral flushing. Check lateral distribution; if cleanouts exist, flush and clean as needed. • Ponding. Check for ponding. Excessive ponding in at-grade and mound beds indicates problems.

Minnesota Pollution Control Agency Chapter 7080 and loca •rdinances. The periodically saturated soils were located at 24-28 inches(mottled soil).Due to The periodically saturated soils,a pressurized Mound System will need to be installed to treat septic effluent.The bottom of the treatment area must be located at least 3'above the saturated soils. The soils at a depth of 12"have a percolation rate averaging 3 MPI. All neighboring wells are located greater than 100'away from proposed treatment area. A lift pump will need to be installed in the lowest level to keep the tanks 50 feet from the wetland. All tanks need to be insulated if there is less than two feet of cover over the top of the tanks.Clean outs must be installed on the end of the laterals for maintenance. 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 pumping chamber. Keep all heavy equipment off of the proposed treatment areas before.during and after construction. The area around both sites must be fenced off by the contractor before any construction begins.This Design is not valid and the System will need to be relocated if failure to protect the areas proposed for On-Site Sewage Treatment occurs. With proper installation and maintenance,this system should have no problem in treating septic effluent effectively.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 tanks every two years Since.ely, ,,, Joseph J.Olson . / / ____-__- .,6 ! / � � ps , '^" , y�^�4 ��`� L_�-- / � � ' / \ / ����n4.
