The <br /> conditions observed during the site evaluation indicate that the area where test pits were located does not <br /> meet minimum standards established by the Department of Environmental Quality. The site is denied for <br /> onsite wastewater treatment. <br /> Most sites have some limitations that will affect the location or type of wastewater system that may be <br /> installed; however,this site is not capable of supporting any Standard or Alternative septic system due to the <br /> following limitations: <br /> Permanent water table is 9"-20" below the surface. <br /> DEQ Rule requirement: <br /> Depth of the Permanent Water Table must be at least 48 inches below the absorption trench for a standard <br /> system, and at least 18 inches below the absorption trench for a sand filter or alternative treatment <br /> technology system under OAR 340-071-0220(1)(b) & OAR 340-071-0290(2)(b). The depth to permanent <br /> water table in the area evaluated is 20"below the surface. <br /> Alternatives—Where to Go From Here <br /> As described above,the soil conditions at this site do not qualify for a subsurface treatment system to serve a <br /> single-family dwelling. <br /> The following options are available: <br /> Apply for a holding tank instead of a drainfield. If the property is being used for commercial purposes that <br /> operate with a projected daily sewage flow under 200-gallons, under OAR 340-071-0340(1)(a), a holding <br /> tank is allowed to be installed to serve the facility. A holding tank cannot be used for a residence. <br /> 5155 Silverton Road NE—Salem,Oregon 97305—Phone(503)588-5147—Fax(503)588-7948 <br /> Page 1 of 3 <br />
