Workdescription: NEW INSTALL: 4 B.DRM:SFD • Conditions of approval Approved Area&System Type Soil test pits and other site features were evaluated during the site visit on May 28,2020. Conditions observed during this site evaluation indicate that the area around the evaluated test holes is not capable of supporting a Standard septic system due to the following limitation: Depth to Soil with Rapid or Very Rapid Permeability DEQ Rule requirement: Soil with rapid or very rapid permeability must be 36"below the ground surface. "Soil with rapid or very rapid permeability"refers to sandy loam or coarser soil with 35%or more coarse fragments • over 2mm;loamy sand or sand; or stones, cobbles, gravel and rock fragments with too little soil material to fill the void spaces. OAR 340-071-0220(1)(c) Description: Treatment of sewage occurs in the soil around the drainfield area. If the sewage enters the groundwater before it has been adequately treated in the soil, it poses a potential public health hazard. A layer of rapid permeability was observed around 30 inches at this site. Under the conditions observed at the above address, a PRESSURIZED DISTRIBUTION OR SEEPAGE BED system is required by DEQ rules for both the INITIAL and an ALTERNATIVE TREATMENT OR BOTTOMLESS SAND FILTER. The PRESSURIZED approval is based on the staking of the property.
