System plans are approved as submitted. Refer to approved plans dated November 28,2018. Any deviation <br /> from the approved plans must be authorized by this office prior to installation or the permit may be voided. It's the responsibility <br /> of applicant/installer to coordinate these requirements with all others in OAR 340-071-0220. <br /> This permit is for a system designed to serve a single family dwelling with a maximum of 4 bedrooms. Peak sewage flow into the <br /> system is limited to a maximum of 450 gallons per day,with an average sewage flow of not more than 225 gallons per day. <br /> Premature failure of the treatment system may occur if either of these flow quantities is exceeded. If,for some reason,you <br /> expect your domestic household water use may exceed these flows, it is advisable to increase the size of the treatment system. <br /> EFFLUENT SEWER:The effluent sewer is the pipe from the septic tank to the distribution box. The material required is 3034 or <br /> Schedule 40 pipe with 18-gauge minimum green tracer wire or green metallic tape placed along the pipe. The effluent sewer <br /> shall extend at least five(5)feet from the tank. There must be a minimum difference of eight(8)inches between the invert(flow <br /> line)of the septic tank outlet and the invert of the distribution or drop box outlet. In Serial Distribution,there must be two(2) <br /> inches of fall between the septic tank outlet and the drop box inlet. <br /> HEADER PIPE between Distribution Box and drainfield trench must measure a minimum of 4 feet, must be installed level,and <br /> bedded on undisturbed earth. <br /> TANK RISER: The tank must be installed with watertight risers extending to the ground surface or above. The riser lid must be <br /> gasketed and securely fastened. <br /> OBSERVE ALL SETBACKS AND SEPARATION DISTANCES as required by the DEQ rules. A copy of the DEQ setback <br /> requirements is on file in our office and available online at http://www.deq.state.or.us/wq/onsite/sdssearch.asp under Rules: <br /> Division 71:Table 1. <br /> MAINTAIN PERMANENT ACCESS to septic tank for pumping and service.The septic tank should be pumped and inspected by <br /> a licensed septic tank pumping service before sludge and scum accumulations reach 30%of the tank liquid operating volume. <br /> Pumping every 3 to 5 years is an average interval. The septic tank is a reservoir for the solid materials in the sewage waste <br /> stream. Excessive accumulation of these solid materials in the septic tank will cause the solids to wash out of the tank and into <br /> the drainfield. This will cause irreversible damage to the drainfield and will eventually lead to a system failure. <br /> THE APPROVED SEPTIC SYSTEM AREA MUST BE PROTECTEDfrom any vehicular traffic, livestock and farming activities. <br /> Other activities such as excavating or filling,driveway placement, paving or other similar activities that alter the natural soil <br /> conditions will adversely affect the soil and the septic system function and lead to premature system failure. The area must not <br /> be subjected to excessive saturation due to artificial drainage of ground surfaces,driveways, building downspouts or other <br /> sources. The areas of the initial septic system and the future repair system must both be protected. <br /> 4/23/19:12:22:44PM Page 2 of 3 ONS_OnsiteCSC_pr <br />
