Septic Authorization 555-19-002375-AUTH Page 2 of 3 fl & ate' Date 'fidq 1171 @ Dat 4116i20 " �Z � g4i 23 0 " V WarptioOA rAMAVYPt Q SIT3 auRM i p a b Conditions of Approval: Existing system information: Marion County records show the existing septic system serving this property was installed in 2017 under permit number 555-17-004858. The system consists of a 1000 gallon concrete dosing septic tank with 375 lineal feet of EZ flow drainline with pressure operated equal distribution via hydrosplitter. Design flow is 450 gallons per day,generally adequate for a single family dwelling with up to four(4)bedrooms. A Certificate of Satisfactory Completion is on file. The septic tank was not pumped or evaluated due to it only being in use since 2018. The site plan shows the proposed structures and concurrent site development can maintain all required setbacks to the existing system. Placement of a three-bedroom single family dwelling will not exceed the design flow of this system. The design of the existing septic system at this address is to serve a single family dwelling of up to four bedrooms,with a maximum daily sewage flow of 450 gallons. This permit DOES NOT infer additional living space and DOES NOT provide for additional daily sewage flow. Flow increase information: According to the DEQ rules for onsite wastewater treatment systems,the proposed increase in projected daily flow,to replace the existing two bedroom single family dwelling with a three bedroom single family dwelling,meets the criteria listed in OAR 340-071-0205(5)(a)-(d)and is an allowable increase for this system.This AUTHORIZATION TO CONNECT TO THE EXISTING ONSITE SYSTEM is approved. Please refer to the signed approved site plan dated April 16,2019. THE APPROVED SEPTIC SYSTEM AREA MUST BE PROTECTED from any vehicular traffic including construction vehicles, livestock and farming activities. Other activities such as logging,excavating or filling, driveway placement 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 PUMPED AND INSPECTED by a licensed septic tank pumping service when sludge and scum accumulation reaches 30%of tank volume(see attached pumping recommendations). Pumping every 3-5 years is average. 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 system failure. Note:This Notice does not guarantee satisfactory or continuous operation of the sewage system. Should the system fail,a repair permit from DEQ is required. If you disagree with this report,you have the right to apply for an authorization notice denial review.The application for review must be submitted in writing within 45 days of the report issuance and be accompanied by the review fee in OAR 340-071-0140(3),Table 9C and any additional information DEQ needs to complete the review. You may apply for a variance to the onsite wastewater treatment system rules. The variance application must include a copy of the site evaluation report, plans and specifications for the proposed system,specify the rule(s)to which a variance is being requested,demonstrate the variance is warranted, and include the variance fee in OAR 340-071-140 Table 9C. A variance may only be granted if the variance officer determines that strict compliance with a rule is inappropriate or special physical conditions render strict compliance unreasonable, burdensome or impractical. A senior DEQ variance officer will be assigned the variance application. 4/17/19:8:40:53AM Page 2 of 3 ONS_OnsiteAuthorizationpr
