The system is comprised of a 1500 gallon two compartment tank and 450 linear feet of drainline. The initial authorization review showed that the proposed addition to the home would not have met setbacks to the septic effluent line. A minor alteration permit was issued and work was completed in September of 2018. The line now meet setbacks,per pictures submitted by the installer. The tank was pumped and inspected by A&B Septic on May 15,2017. The pumper noted no signs of failure. Flow increase information: The system was designed to serve a dwelling with up to four bedrooms and a maximum sewage flow of up to 450 gallons per day. The application is to connect a 1-bedroom addition to this system for a total of 4 bedrooms. This change of use will result in an addition of 75 gallons per day and can be approved under Oregon Administrative Rule(OAR)340-071-0205(4). Please see the signed approved site plans dated March 6,2019. EFFLUENT LINE: Schedule 40 1 %inch pipe per submitted plans. OBSERVE ALL SETBACKS AND SEPARATION DISTANCES: As required by the DEQ rules. The well placement is especially critical and must be located at least 50-feet from the septic tank. A minimum 5-foot setback is required from the septic tank to a foundation of a building or other structure. A copy of the DEQ setback requirements is enclosed. 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 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 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. THIS SYSTEM MUST BE INSPECTED AND APPROVED PRIOR TO BACKFILL. When work is complete and ready for inspection,request an inspection by following the instructions on the accompanying permit document. A twenty four hour water test is required on all septic tank installation.You may leave a message for the inspector if desired. Be sure the System Record form with the As-Built drawing is on the job or in our office when the inspection is requested. An inspection should be completed within seven(7)days. 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.
