The primary system was installed in 1977 under permit number 290. It consists of a 1000 gallon tank and 300 linear feet of line. The smaller system was constructed to serve an art studio and was installed in 1986 under permit number 86-304. It consists of a 1000 gallon tank and 100 linear feet of line. A Certificate of Satisfactory Completion is on file for both systems. The septic tanks were most recently pumped and inspected by Coffman Excavation on March 26, 2019. No signs of failure were reported. A site visit was made to the address on April 3,2019 in response to an application to connect a 4-bedroom dwelling to the existing system(s). The system was partially exposed for inspection and was not in use at the time of the visit. There were no signs of failure present. There is adequate room for a repair system. Flow increase information: According to the DEQ rules for onsite wastewater treatment systems,the increase in projected daily flow from 3-bedroom single family residence to a 4-bedroom single family residence meets the criteria listed in OAR 340-071-0205(5)(a)-(d)and is an allowable increase for this system. This AUTHORIZATION TO increase the number of bedrooms is approved. Please see the approved signed site plans dated April 9,2019. THE APPROVED SEPTIC SYSTEM AREA MUST BE PROTECTEDfrom 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 inspectedby a licensed septic tank pumping service approximately every five(5) years. 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. 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 4/10/19 4/10/19:3:54:28PM Page 2 of 2 ONS_OnsiteAuthorization_pr
