The conditions observed during this site evaluation indicate that the area around the evaluated test pits is not capable of supporting a standard system due to depth to a seasonal water table. Under OAR 340-071-0220, the seasonal water table cannot rise closer than 24 inches to the native ground surface. At your site conditions associated with saturation were noted at 18, 19 and 24 inches. Under these conditions, a standard system is allowed under RURAL AREA CONSIDERATION in the vicinity of test pits#1 and#3. Property is located in a designated rural zone (EFU) and meets all conditions for OAR 340-071-0410. System design and permit conditions depart from temporary water table standard 340-071-0220(1)(b)(B) and will function without creating a public health hazard or polluting public waters. Sites approved under Rural Area Consideration are limited to a projected daily sewage flow not to exceed 600 gallons per day. This Permit is for a system designed to serve a single family dwelling with a maximum of five bedrooms. Peak sewage flow into the system is limited to a maximum of 525 gallons per day, with an average sewage flow of not more than 263 gallons per day.
