Pernel"Chip" Hentges 16762 Babcock Ave. Lester Prairie,MN 55354 952-200-3176 chipseptic cr,gmail.com Minnesota Pollution Control Agency Individual Sewage Treatment System License No. 2064 For: M & M Contractors 413 Paul Ave South Cologne, MN 55322 Location of proposed septic system site: PID# 0611723220029 125 Bayside Trail Orono, MN 55359 This site will be designed for an Above Grade Drain field upgrade The site must remain protected until construction begins. (This is the responsibility of the owner and or General Contractor) This site evaluation was completed on December, 12, 2017. It is for a type one dwelling with and estimated flow of 750 gallons per day. Soils information indicated a seasonal water table at 12 inches. An above grade drainfield will be used to meet the 3 foot separation from the seasonal high watertable as required by MPCA Agency Rules and Standards, Chapter 7080,81. The Mound System design area is 46 feet wide with a length of 99 feet. Pin Flags and lath have marked the location of the soil borings, plus the boundary of the rockbed and drainfield. The proposed system will require(1) 1250-gallon septic tank, (1) 1000 gallon septic tank, and (1) 1500 gallon dosing tank. The pump will need to be sized to deliver 36 gallons per minute with a lift of 21 feet of total head. An Effluent filter will be installed in the second tank and must be cleaned twice a year (spring and fall). This is the responsibility of the owner, The tanks two foot manhole risers on the septic and pump tank will need to be raised to be above the ground surface a minimum of 6 inches for maintenance and access to the tanks. The set-back for the well from the septic system area must be a minimum of 50 feet for both the septic tanks and the absorption area. The septic tanks will need to be at least 10 feet from the edge of the house and the absorption field must be 10 feet away from property lines. It is the responsibility of the owner to identify the property boundaries for designing and installing the septic system. The septic system if properly installed and maintained should have no problems treating effluent in the matter that it was designed for. Nothing other than human waste, toilet tissues, shower, sink, dishwasher and laundry water should be drained to the septic tanks and treatment field. If you have water treatment systems other than water softeners, in ex. Iron filters, they should be diverted from entering the septic system. Garbage disposals are not recommended, as they will add more solids to your septic tanks and may allow fine particles to enter the treatment area and clog the system. Daily toilet bowl cleaners, shower sprays (that are used after every shower), and excessive cleaning agents may kill bacteria needed to treat septic effluent. Additives are not needed, and are not recommended in properly maintained septic system. You should have your septic tanks pumped and inspected for proper maintenance by a certified pumper every 2 years. General The soil conditions have been established at the test hole location only. There may be variations in soil stratigraphy between and around the borings and interpolation and extrapolation of the results is not warranted.

I hereby certify that I have completed this septic system design work in accordance with MPCA's Rules and Standards Chapter 7080-81, local ordinances, rules and laws.

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.

Chart on page 6 can help track your activities. Your toilet is not a garbage can.Do not flush anything besides human waste and toilet paper. No wet wipes, cigarette butts,disposal diapers,used medicine,feminine products or other trash! The system and septic tanks needs to be checked every 6 months Your service provider or pumper/maintainer should evaluate if your tank needs to be pumped more or less often. Seasonally or several times per year • Leaks. Check(listen,look) for leaks in toilets and dripping faucets. Repair leaks promptly. • Soil treatment area. 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 and leaks,call your service professional. Untreated sewage may make humans and animals sick. Keep bikes, snowmobiles and other traffic off and control borrowing animals. • Alarms. Alarms signal when there is a problem; contact your service professional any time the alarm signals. • Lint filter. If you have a lint filter,check for lint buildup and clean when necessary. If you do not have one,consider adding one after washing machine. • Effluent screen. If you do not have one, consider having one installed the next time the tank is cleaned along with an alarm. Annually • Water usage rate. A water meter or another device 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. Consider updating to demand operation if your system currently uses time, • Review your water usage rate. Review the Water Use Appliance chart on Page 5.Discuss any major changes with your service provider or pumper/maintainer. During each visit by a service provider or pumper/maintainer • Make sure that your service professional services the tank through the manhole. (NOT though a 4"or 6"diameter inspection port.) • Ask how full your tank was with sludge and scum to determine if your service interval is appropriate. • Ask your pumper/maintainer to accomplish the tasks listed on the Professional Tasks on Page 4. - 3 - Septic System Management Plan UN I V ERS ITYfor 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. At each visit a written report/record must be provided to homeowner. 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 soil treatment area.) • Inspection pipes.Replace damaged or missing pipes and 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 draining properly. • Event counter or elapsed time meter. Check to see if there is an event counter or elapsed time meter for the pump. If there is one or both,calculate the water usage rate and compare to the anticipated use listed on Design and Page 2. Dose Volume: gallons: Pump run time: Minutes Soil Treatment Area • Inspection pipes. Check to make sure they are properly capped. Replace caps and pipes that are damaged. • Surfacing of effluent. Check for surfacing effluent or other signs of problems. • Lateral flushing. Check lateral distribution; if cleanouts exist, flush and clean at recommended frequency. • Vegetation-Check to see that a good growth of vegetation is covering the system.
