Work Desalptignc MA/REP EXIST 3BDRMRES PARCEL Sd OF 2 P16-12 2 AC PARCEL� - ' Conditions of Approval Approved Area&System Type Test pits and other site features were evaluated on August 8,2017. The conditions observed during this site evaluation indicate that the area around the test pit is capable of supporting a STANDARD system for the REPAIR. Plans are approved as revised. Please refer to the signed approved site plan dated September 19,2017. Any deviation from the approved plans must be authorized by this office prior to installation or the permit may be voided. It is the responsibility of applicant/installer to coordinate these requirements with all others in OAR 340-071-0220. This Permit is for a system designed to serve a single family dwelling with a maximum of 4 bedrooms. Peak sewage flow into the system is limited to a maximum of 450 gallons per day,with an average sewage flow of not more than 225 gallons per day. Premature failure of the treatment system may occur if either of these flow quantities is exceeded. If,for some reason, you expect your domestic household water use may exceed these flows,it is advisable to increase the size of the treatment system. Specific Requirements EFFLUENT SEWER:The effluent sewer is the pipe from the septic tank to the distribution box. The material required is 3034 or Schedule 40 pipe with 18-gauge minimum green tracer wire or green metallic tape placed along the pipe. The effluent sewer shall extend at least five(5)feet from the tank. There must be a minimum difference of eight(8)inches between the invert(flow line)of the septic tank outlet and the invert of the distribution or drop box outlet. In Equal Distribution,there must be six(6)inches of fall between the septic tank outlet and the distribution box inlet. In Serial Distribution,there must be two(2) inches of fall between the septic tank outlet and the drop box inlet. DRY SOIL CONDITIONS ARE REQUIRED FOR INSTALLATION(March 1—October 31) The geographical area in which the property lies is considered a risk to installation during winter months. Soil moisture conditions generally preclude construction of the drainfield in the winter months. THE ATTACHED SEPTIC TANK ABANDONMENT FORMMUST BE COMPLETED AND RETURNED TO OUR OFFICE. The septic system installer must complete and sign the form and attach a copy of the receipt from the septic tank pumping service for pumping the tank. HEADER PIPE between Distribution Box and drainfield trench must measure a minimum of 4 feet,must be installed level, and bedded on undisturbed earth. OBSERVE ALL SETBACKS AND SEPARATION DISTANCES as required by the Department of Environmental Quality rules. A copy of the DEQ setback requirements is available in our office and online at http.//www.oregon.gov/deq/Residential/Pages/Onsite.aspx under Rules: Division 71:Table 1. THE APPROVED SEPTIC SYSTEM AREA MUST BE PROTECTED from any vehicular traffic, livestock and farming activities. Other activities such as excavating or filling,driveway placement, paving or other similar activities that alter the natural soil conditions will adversely affect the soil and the septic system function and lead to premature system failure. The area must not be subjected to excessive saturation due to artificial drainage of ground surfaces,driveways, building downspouts or other sources. The areas of the initial septic system and the future repair system must both be protected. MAINTAIN PERMANENT ACCESS to septic tank for pumping and service.The septic tank should be pumped and inspected by a licensed septic tank pumping service before sludge and scum accumulations reach 30%of the tank liquid operating volume. Pumping every 3 to 5 years is an average interval. The septic tank is a reservoir for the solid materials in the sewage waste stream. Excessive accumulation of these solid materials in the septic tank will cause the solids to wash out of the tank and into the drainfield. This will cause irreversible damage to the drainfield and will eventually lead to a system failure.
