General Description of Site Evaluations Sewage contains disease-causing organisms and other pollutants that can case 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 tan c 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 treatmnt,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 rinatter,and most nutrients. Effluent that comes to the ground surface(through poor soils or other problems with the sy tem)can be a possible health hazard because it may still contain some disease-causing organisms. Soil that drain 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 •❑coccocc Depth to evidence of groundwater •❑❑❑❑❑n❑❑Wells located on the site or adjacent sites •❑❑❑❑coop Slopes,escarpments, ground surface variations,topography •❑❑❑❑❑❑❑❑Creeks or springs on the site or adjacent properties •❑❑❑❑corn Whether the soils have been disturbed •❑❑❑❑❑co❑Setbacks from property lines, buildings,water lines, and other utili ies •❑❑❑❑noon Other site features that could affect the placement of your onsite s stem Approved Area&System Type Soil test pits and other site features were evaluated during site visits on Marc 18,2019. The conditions observed during these site evaluations indicate that the area around the evaluated test pits IS APABLE of supporting a STANDARD SEPTIC SYSTEM for the INTITIAL and REPAIR in the area of test pits num Bred 3,4,and 5 ONLY. Test pits#1 and#2 are DENIED due to the proximity to the neighboring septic system. Test pits and#7 are approved only for an ATI- SYSTEM TTSYSTEM and should be AVOIDED. Please refer to the approved site plans d ted March 20,2019 for specific installation details. Specific Requirements Please refer to the Soil Notes/Site Evaluation Worksheet which shows the ap roved areas and other details of the site visit. • DRY SOIL CONDITIONS ARE REQUIRED FOR INSTALLATION(March 1— ctober 31).The geographical area in which the property lies is considered a risk to installation during winter months. Soil oisture conditions generally preclude construction of the drainfield in the winter months. A DETAILED SEPTIC SYSTEM STAKEOUT IS REQUIRED prior to the issua I ce of a septic system installation permit. The area for the system rests on irregular terrain. A stakeout of both initial and r placement fields must be completed to Y 9 p P determine that the system will fit on the contour and within the area of the a roved test pits. A scale drawn,detailed site Y P plan must be submitted with the application for the installation permit. The st keout must be inspected on the property and approved before the permit can be issued. Instructions for the stakeout are attached and are available in our office. Additional Conditions of Site Approval 1. This site is approved for the type of disposal system described above. P ak sewage flow into the systemis limited to a CALL BEFORE YOU DIG..ITS THE LAW ATTENTION:Oregon law requires you to follow rules adopted by the Oregon Utility Notification Center. Those les are set forth by Oregon Administration Rules. You may obtain copies of the rules by calling the center.(Note:The telephone number for the Oregon Utility Notification Center is 1-800-332-2344.) 3/21/19:11:06:03AM Page 3 of 4 ONS_OnsiteEvaluation_pr
