Conditions of approval Approved Area&System Tyke Test pits and other site features were evaluated on April 22,2019. 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 April 22,2019. 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 per gallons per day. Premature failure of the treatment system may occur if either of these flow quantities is exceeded. ADDITIONAL DRAINFIELD IS HIGHLY RECOMMENDED DUE TO THE SITE OF THE FUTURE HARDSHIP DWELLING. 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 TANK RISER: The tank must be installed with watertight risers extending to the ground surface or above. The riser lid must be gasketed and securely fastened. 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 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. DO NOT INSTALL SYSTEM DURING WINTER MONTHS(Nov.1—March 1) The geographical area in which the property lies is considered a risk to installation during winter months. Therefore,for this installation a Marion County Onsite Wastewater Specialist must specifically approve this site for installation from November 1st to March 1st. This may include a field visit directly prior to installation 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. 4/23/19:11:00:24AM Page 3 of 4 ONS_OnsitePermitjr
