Septic Site Evaluation 555-21-009085-EVAL Page 4 of 5 • Date issued:,',n 07'2021 Application status Site Evaluatror.Approved', Work description:SE FUTURE ' BDPN1 SFu (LOT OF_ F 21 224 y4 0t . �; '? . Conditions of approval: flow quantities is exceeded. If,for some reason,you expect your water use may exceed these flows, it may be advisable to increase the size of the treatment system. 2. Any alteration of natural soil conditions(i.e. cutting,tilling, logging, or filling) in the acceptable area may void this approval. 3. Both the initial and replacement disposal areas are to be protected from traffic, livestock and farming activities, development or other potential disturbance of natural soil conditions. 4. The area must not be subjected to excessive saturation due to, but not limited to, artificial drainage of ground surfaces, roads, driveways and building down spouts. 5. This approval is given on the basis that the parcel described above will not be further partitioned or subdivided. 6. Placement of a well within 100 feet of the approved areas may invalidate this approval. General Description of Site Evaluations Sewage contains disease-causing organisms and other pollutants that can cause adverse impacts to human health and the environment. An onsite sewage disposal system must treat and dispose of sewage in a way that will not cause a public health hazard, contaminate drinking water supplies, or pollute public waters. Proper treatment in an onsite system begins with primary treatment in the septic tank. The septic tank separates the solid particles in sewage from the liquid. The liquid that comes out of the septic tank is called effluent. The effluent may then be dispersed in the soil for further treatment or discharged into a secondary treatment device such as a sand or gravel filter or other alternative treatment unit prior to dispersal in the soil. For proper treatment,the effluent must slowly infiltrate into the underlying soil. Dissolved wastes and bacteria in the effluent are trapped or adsorbed to soil particles or decomposed by microorganisms. This process removes disease-causing organisms,organic matter, and most nutrients. Effluent that comes to the ground surface(through pcor soils or other problems with the system)can be a possible health hazard because it may still contain some disease-causing organisms. Soil that drains too quickly may not give the effluent enough treatment and may result in groundwater contamination. The purpose of the evaluation is to locate suitable soils in an area that is large enough for both the initial drainfield area and the replacement drainfield area. The criteria used for this site evaluation can be found in Oregon Administrative Rules(OAR) 340-071. In the site inspection,the following features are evaluated: • Soil types-how well they drain and other indicators of good soil structure for treatment • Depth to evidence of groundwater • Wells located on the site or adjacent sites • Slopes,escarpments, ground surface variations,topography • Creeks or springs on the site or adjacent properties • Whether the soils have been disturbed • Setbacks from property lines, buildings,water lines, and other utilities • Other site features that could affect the placement of your onsite system Request for Site Evaluation Report Review or Request for Variance If you believe that an error was made in the evaluation of your property,you may apply for a Site Evaluation Report Review. If you would like to apply for a Variance from one or more of the Onsite Wastewater Treatment and Disposal rules, you may apply for a Variance. Each review will require a fee. If you are interested in either of these actions,please contact Jessica Joye at DEQ for more details before you proceed: Jessica Joye, REHS DEQ NW Region Onsite Wastewater Management Specialist4026 Fairview Industrial Drive SESalem, OR 97302 503.378.5033 Joye.jessica@deq.state.or.us CALL BEFORE YOU DIG...ITS THE LAW ATTENTION:Oregon law requires you to follow rules adopted by the Oregon Utility Notification Center.
