Septic Authorization 555-19-006036-AUTH Page 2 of 2 Conditions of Approval: Marion County records show the existing septic system serving this property was installed in 1973.The system consists of a 1000 gallon single compartment concrete tank with approximately 180 lineal feet of rock and pipe drainfield. Design flow is 300 gallons per day,generally adequate for a single family dwelling with up to two(2)bedrooms.The drainfield was located during an ESER by Ralston Excavation the distribution box and header pipe were replaced during the ESER locate and no permit was taken out.This process of installing a box and header without a permit is approved in Marion County per discussion with Matt Putney and Claudia Hill on 12/2/10. Flow increase information: The site plan shows the proposed structures and concurrent site development can maintain all required setbacks to the existing system. Placement of a two-bedroom single family dwelling will not exceed the design flow of this system.This meets the criteria listed in OAR 340-071-0205(4)(a)-(c)and is an allowable connection to this system.THIS AUTHORIZATION TO CONNECT TO THE EXISTING ONSITE SYSTEM IS APPROVED. Please refer to the signed approved site plan dated April 2, 2019. TE APPROVED SYSTEM ARA MUST BE PROTECTED from any vehicular traffic,and livestock activities. Other activit es such as logggging,excavating or fill ng,driveway placement,paving or any similar activities may also damage the soil in the area and adversely affect the septic system approval. The areas of the initial septic system and the future repair system must both be protected. THE SEPTIC TANK SHOULD BE PMPED AND INSPECTED by a licensed septic tank pumping service approximately EVERY FIVE(5)YEARS. The septictank should be pumped before solids reach 30%of the tank liquid operating level. 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 lead to premature system failure.
