The system consists of a 1000 gallon concrete tank and approximately 280 linear feet of drainline.The system was designed for a 3-bedroom dwelling. The system was pumped, inspected, and located by Oregon Sewer&Drain on May 1,2019.-The technician noted a 1000 gallon - - - tank and was able to located approximately 120+feet of drainline. The system was partially crushed beyond a certain point in the drainlines. The technician noted no signs of failure but stated the outlet baffle was in need of replacement. A field visit was made in response to an application to connect a 3-bedroom dwelling to the existing system. The system was not in use at the time of the visit and was partially exposed for inspection. An access road occurs over the end portion of the drainfield. There was no sign of failure present.There is adequate room for a repair system.The baffles were replaced recently by Oregon Sewer&Drain.A RISER TO THE GROUND SURFACE IS HIGHLY RECOMMENDED. 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 three-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 June 20, 2019. THE APPROVED SEPTIC SYSTEM AREA MUST BE PROTECTED from any vehicular traffic, livestock and farming activities. Other activities such as logging,excavating or filling, 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 PUMPED AND INSPECTED by a licensed septic tank pumping service approximately EVERY -FIVE(5)YEARS. The septic tank 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. 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. Matthew Puntney Onsite Inspector 6/20/19 6/21/19:11:28:01AM Page 2 of 2 ONS_OnsiteAuthorization_pr
