The conditions <br /> observed during this site evaluation indicate that the area around the evaluated test <br /> pits is not capable of supporting a standard system due to depth to a seasonal water <br /> table. Under OAR 340-071-0220, the seasonal water table cannot rise closer than 24 <br /> inches to the native ground surface. At your site conditions associated with saturation <br /> were noted at 18, 19 and 24 inches. <br /> Under these conditions, a standard system is allowed under RURAL AREA <br /> CONSIDERATION in the vicinity of test pits #1 and #3. Property is located in a <br /> designated rural zone (EFU) and meets all conditions for OAR 340-071-0410.

Sites approved under Rural Area Consideration are limited to a <br /> projected daily sewage flow not to exceed 600 gallons per day. <br /> This Permit is for a system designed to serve a single family dwelling with a maximum <br /> of five bedrooms. Peak sewage flow into the system is limited to a maximum of 525 <br /> gallons per day, with an average sewage flow of not more than 263 gallons per day. <br /> Premature failure of the treatment system may occur if either of these flow quantities <br /> is exceeded.
