Co., MN WITHisPLAN S1iT+Rl~iWIAlALA.TIAM4 A compliance inspection was completed for the existing on-site sewage treatment system located on this property. The system consists of 2-1000 gallon tanks &three trenches 65' long built in 1974. Soil boring #4 found mottled soil (redox features) at 38" below the ground surface &the bottom of the trenches at 34" & 36" below the ground surface. Soil boring #5 found mottled soil at 56" & the bottom of the trenches at 36" below the surface. The system does not meet a 2' separation from the bottom of the trenches & redox features & is classified as non-compliant, failing to protect the ground water. Also the lowest trench at the north end effluent is ponding 8" above the rock with black & gray soils to the surface. The black & gray color indicates that the system has surface discharged & has the potential to be an imminent threat to public health which requires an upgrade within 10 months or as determined by the City of Orono. This on-site sewage treatment system is designed for a Type 1, four bedroom home, in accordance with the Minnesota Pollution Control Agency Chapter 7080 and local ordinances. The soils on this site are a sandy loam clay loam. The periodically saturated soils were located at 34", 42" & 68" (redox features). Due to the seasonally saturated soils, a Pressurized Mound System will need to be installed to treat septic effluent. The bottom of the rock must be located at least 3' above the saturated soils. ORONO COPY The soils at a depth of 12" have a percolation rate of 8.0 mpi. The existing tanks may be used if water tight. If new tanks are installed, the site is heavily wooded. Use Norwesco Bruiser tanks. MOS IS 11$160 POI ilDNIVAL Mt ORONO COPY 1 • ' ' r ,� 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 weather proof enclosure. A warning device must be installed with a light and sound device, this is in case of a pump failure. The manifold and supply line pipe must have back drainage to the pumping chamber. The distribution pipes shall have their ends capped. Be sure the rock and sand fill material are clean. The sod layer below the entire mounded area must be turned over, just break up the sod, be sure not to over work. If the tanks have less than 2' of cover, the lids, risers & maintenance hole covers must be insulated to a value of R10. Cleanouts for each later must be installed & be accessible from finish grade in an irrigation box with a ball valve. All neighboring wells are located greater than 100' away from the proposed treatment area. Keep all heavy equipment off of the proposed treatment area before and after construction. The treatment area should be marked off before construction. This Design is not valid &the system will need to be relocated if failure to protect the areas proposed for On-Site Sewage Treatment occurs. MANAGEMENT PLANS: The tanks need to be pumped every 2 years. Check with your pumper to set up a schedule. System inspected for wet areas by owner & or Inspector as determined by the local unit of government. Any other requirements as determined by the local unit of government With proper installation and maintenance, this system should have no problem in treating septic effluent effectively. 2 Nothing other than human waste, toilet tissue, laundry, showers, water softener etc. should be disposed of into the septic tanks. Recommend Iron filters be diverted out of the system. Recommend to divert the water softner also if the iron filter is diverted. Garbage disposals are not recommended, due to adding more solids &fine solids passing through to the system. Excessive amounts of soaps, antibacterial soaps, cleaning agents, shower cleaners used every shower & chlorine agents may kill the bacteria needed to treat septic effluent. Additives are not recommended. Recommend laundering be limited to 3 to 4 loads per day. Steven B. Schirmers 3 0 DATE TIME CITY OF ORONO CALLED IN INSPECTION NOTICE SCHEDULED PERMIT NO.

The soils on this site are a loam to sandy loam. The seasonally saturated soil, mottled soil(redox features)were present at a depth of 32"to 40"with standing water in boring#3 at 32". A pressurized mound system will be installed. The bottom of the treatment area must be located at least 3'above mottled soil. The proposed site is located down slope of the existing mound. The rock bed and down slope toe of the mound are located on original soil. The upsiope toe from the upslope edge of the rock bed will overlap the down slope toe of the existing mound which is not part of the absorption area for the alternate site. The area shown on the site plan will support a 5 bedroom home(10'x 62'rock bed) with a 40'x 92'basal area. All property lines must be located prior to installation. All neighboring wells are located greater than 100'away from the proposed treatment area. Keep all heavy equipment off of the proposed treatment area before and after construction. The treatment area should be marked off before construction. This design is not valid&the system will need to be relocated if failure to protect the sites for new on-site sewage systems.
