INSPECTION REPORT �9kEsHo4+ Owner: l4,447 tib.1 4'"C4/1 Address: . l it a ia05/AVS Permit #'s: AOTe, Dates: Contractors: City ordinance number 100 requires that each on-site sewage treatment system in Orono be inspected on a regular basis. The on-site sewage treatment system at the above address has been inspected and appears to fall into the category checked below. (This is , -an existing system [ ] new construction) SYSTEM CONFORMITY (1-3): oc 1 "CODE SYSTEM"-A system which meets all the location, design, and construction standards of the current City Codes, and which is operating satisfactorily by treating and disposing of the entire current sewage input ) without discharging any pollutants into ground or surface waters. 6) without SYSTEM"-A system which does not meet all the location, design, and construction standards of the current City Codes, but was installed according to the code in effect at the time of installation, and which is operating satisfactorily by treating and disposing of the entire current sewage input without discharging any pollutants into ground or surface waters. 3 "NON-CONFORMING SYSTEM"-A prohibited system; a system located within a designated 100-year floodplain; any system which may or may not meet all the location, design, and construction standards of the current City Codes and which is failing for any reason; and any system with less than 3 feet of unsaturated soil or sand between the distribution device and the limiting soil characteristics. (The limiting soil characteristic ( ] has or , 1.has not been identified at this time. If the limiting soil characteristic has not been identified, this classification may be subject to revision.) TANK CONDITION (5-10): 4 Tank inspection indicates: Pumpout not needed at this time. Solids accumulation in tanks indicates they should be ;�• • out this ear to 1- • • - ent future problems. So i•s acc ,' - ion in s is a .• . •• • • out as soon as poS�Tble.---� 8 System is discharging to the surface. Tanks must be pumped out within 48 hours to eliminate surface discharge. 9 Inspection risers missing-tanks could not be inspected. Inspection risers (4" dia. pipe) must be installed in each tank at next punpout. If tanks have not been pupped out within the last three years, they should be pupped out now. 10 Inspection pipe is located directly over tank baffle (does not give accurate measurement of solids accumulation). If tanks have not been pupped out within the last three years, they should be pumped out now. DRAINFIELD CONDITION (11-14):// D field inspection indicates: Drainfield is dry, no surfacing evident. 4.2 Some evidence of surfacing, not critical yet. 13 Drainfield is saturated and visibly discharging untreated effluent to the surface. Contact the City Inspector immediately. Repairs must be completed within 90 days. 14 Drainfield extent and condition unknown.

S. OWNER: //ou/a di GENERAL CONTRACTOR: SEPTIC CONTRACTOR: SITE EVALUATOR: S—P Testing REPORT DATE: January 5, 1994 The City of Orono has Approved your on-site system design as of January 12, 1994 (approved-disapproved) (date) with the following comments:When the eastern drainfield site is used, an interceptor drain must be installed to remove upslope drainage. Based on the soil testing information, a four bedroom home is the maximum allowable on this lot. THIS IS NOT A PERMIT. This is a design approval form which must accompany the site plan. A permit must be issued to a licensed septic contractor prior to installation. A list of currently licensed septic contractors is enclosed. NOTICE TO INSTALLERS: Any changes to the approved plans and specs must have prior approval of the Inspector (473-7357). Call for inspections 24 hours in advance. ALL DRAINFIELD AREAS MUST BE FENCED OFF prior to building site excavation and fencing must remain in place until final site grading. Approval to pour footings will not be granted until the Inspections Department has verified that primary and alternate sites are adequately protected. NO VEHICULAR TRAFFIC OF ANY KIND (cars, trucks, earth moving equipment, etc.) is allowed within 20' of tested drainfield sites either before or after system construction. Compaction of these areas could render them unusable prohibiting the timely completion and or limiting the long term use of the property. A site copy will be available at the City Offices for the septic contractor. CITY OF ORONO By 444 I Stephen ckman, On-site Systems Manager TELEPHONE-473-7357• FAX-473-0510 • • S-P TESTING, INC. Steven B. Schirmers — MPCA Cert. No. 627 951 Katydid Lane NE • St. Michael, MN 55376 • (612) 497-3566 January 5, 1994 Allen McDowell Lot 1, Block 1 Smith Dettloff Addition Orono, Henn. Co. , MN This On-Site Sewage Treatment System is Designed for a Type 1, Four Max. bedroom home Designed in accordance with the Minnesota Pollution Control Agency Chapter 7080 and local ordinances . The soils on this site are SCS soils mapped - KkB - Kilkenny loam. A seasonally high water table was located at 14" to 30" , (mottled soil ) . Due to the seasonally high water table, a Pressurized Mound System will need to be installed. The bottom of the rock bed must be located at least 3 ' above the seasonally high water table. The soils at a depth of 12" have a percolation rate averaging 10 .5 min/inch. If the south site is used for the primary site, an Interceptor Drain will need to be installed. A pumping chamber will need to be installed to lift the effluent to the treatment area. The manifold and supply line pipe must have back drainage to the pumping chamber. The ditribution 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. 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. (mercury floats are a good method) . All neighboring wells are located greater than 100 ' away from the proposed treatment area . CONT' D Allen McDowell Lot 1, Block 1 Smit Dettloff Addition Orono (2) 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 . With proper installation and maintenance, this sytem should have no problem in treating septic effluent effectively. Nothing other than gray water, (laundry, showers , etc. ) human waste & toilet tissue should be disposed of into the septic tanks . Garbage disposals are not recommended. Smaller amounts of laundry soaps , dish soaps , cleaning agents, etc. are better for the system. Antibacterial soaps & chlorine agents may kill the bacteria needed to treat septic effluent properly. Additives are not recommended, they may cause harmful damage to your system. Recommend to pump & clean your tanks by a certified pumper every year if you have 1 tank & every 2 years if you have 2 tanks to insure proper maintenance. Note : This site has a max. 4bedroom, 600gal . /day area available. Driveway easement to the south must be located. Steven B.
