The system consists of a 1000 gallon concrete septic with 400 lineal feet of rock and pipe drainline with serial distribution. A certificate of satisfactory completion is on file.A new plot plan has been created showing that the proposed home will meet setbacks to the septic tank and drainfield. The tank was pumped by Farmers Septic on April 20,2021,and found to be in good condition,the drainfield was evaluated on the same day by Action Drain and found to be in working condition. This system was previously authorized in 2021 (555-21-004984)for replacement of a 3 bedroom dwelling with a 3 bedroom dwelling,a 4 bedroom is now proposed.No site visit is required in this case. Authorization information: According to the DEQ rules for onsite wastewater treatment systems,THIS AUTHORIZATION TO CONNECT THE REPLACEMENT DWELLING TO THE EXISTING ONSITE SYSTEM IS APPROVED under Oregon Administrative Rule(OAR) 340-071-0205(4). Please see the approved signed site plans dated March 22,2023. THE APPROVED SEPTIC SYSTEM AREA MUST BE PROTECTED from any vehicular traffic including construction vehicles, livestock 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 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. Robert Goo win Onsite Wastewater Specialist 2 3/22/23 /01 .
