Anonsitesewage disposal system must treat and dispose of <br /> sewage in a way that will not cause a public health hazard, contaminate drinking water supplies, or <br /> pollute public waters. <br /> Proper treatment in an onsite system begins with primary treatment in the septic tank. The septic tank <br /> separates the solid particles in sewage from the liquid. The liquid that comes out of the septic tank is <br /> called effluent. The effluent may then be dispersed in the soil for further treatment or discharged into a <br /> secondary treatment device such as a sand or gravel filter or other alternative treatment unit prior to <br /> dispersal in the soil. For proper treatment, the effluent must slowly infiltrate into the underlying soil. <br /> Dissolved wastes and bacteria in the effluent are trapped or adsorbed to soil particles or decomposed <br /> by microorganisms. This process removes disease-causing organisms, organic matter, and most <br /> nutrients. Effluent that comes to the ground surface (through poor soils or other problems with the <br /> system)can be a possible health hazard because it may still contain some disease-causing <br /> organisms. Soil that drains too quickly may not give the effluent enough treatment and may result in <br /> groundwater contamination. <br /> The purpose of the evaluation is to locate suitable soils in an area that is large enough for both the <br /> initial drainfield area and the replacement drainfield area. The criteria used for this site evaluation can <br /> be found in Oregon Administrative Rules (OAR) 340-071. <br /> In the site inspection, the following features are evaluated: <br /> •0001:10000 Soil types- how well they drain and other indicators of good soil structure for treatment <br /> •❑❑❑❑❑❑❑❑ Depth to evidence of groundwater <br /> •❑0❑❑0❑❑❑Wells located on the site or adjacent sites <br /> •❑❑❑❑❑❑❑❑Slopes, escarpments, ground surface variations, topography <br /> •00000❑❑❑Creeks or springs on the site or adjacent properties <br /> •0❑❑❑❑❑❑❑Whether the soils have been disturbed <br /> •❑❑❑❑❑❑❑❑Setbacks from property lines, buildings, water lines, and other utilities <br /> •❑❑000000 Other site features that could affect the placement of your onsite system <br /> Approved Area&System Type <br /> Soil test pits and other site features were evaluated during site visits on June 21, 2019. The conditions <br /> observed during these site evaluations indicate that the area around the evaluated test pits IS <br /> CAPABLE of supporting a STANDARD SEPTIC SYSTEM for the INTITIAL and REPAIR. Please refer <br /> to the approved site plans dated June 26, 2019. • <br /> Specific Requirements <br /> Please refer to the Soil Notes/Site Evaluation Worksheet which shows the approved areas and other <br /> details of the site visit. <br /> DRY SOIL CONDITIONS ARE REQUIRED FOR INSTALLATION (March 1 —October 31).The <br /> CALL BEFORE YOU DIG..ITS THE LAW <br /> ATTENTION:Oregon law requires you to follow rules adopted by the Oregon Utility Notification Center. Those rules are set forth by Oregon Administration Rules. You may obtain <br /> copies of the rules by calling the center.(Note:The telephone number for the Oregon Utility Notification Center is 1-800-332-2344.) <br /> 6/26/19:3:15:43PM Page 3 of 5 ONS_OnsiteEvaluation_pr <br />
