<br /> Please use caution when preparing the site for any septic system or structures.
<br /> With a Capping Fill drainfield,the effective soil depth may be 18"from the ground surface in soil no finer than silty clay
<br /> loam. Under the conditions observed at the above address, a CAPPING FILL DRAINFIELD is required in the area of any of
<br /> the four test pits. Please refer to the signed approved site plan dated March 26,2019.
<br /> CAPPING FILL systems are installed in soils where a layer that limits the effective soil depth or a water table is present in
<br /> the soil profile at a depth shallower than allowed for a Standard system. The disposal trenches are installed at a very
<br /> shallow depth and approved fill is placed over the trenches to provide earth cover over the system. Fill material must be
<br /> evenly graded over the DRAINFIELD and crowned at the center to shed rainfall. CAPPING FILL SYSTEMS MAY ONLY BE
<br /> INSTALLED BETWEEN JUNE 1 AND OCTOBER 1 or during such times when the Building Inspection Onsite Wastewater
<br /> staff finds soil moisture conditions acceptable. See the attached"CAPPING FILL"
<br /> information sheet for instructions.
<br /> AN EFFLUENT LIFT PUMPWILL BE REQUIRED to install the septic system disposal field in the approved area and at the
<br /> required depth. Detailed instructions for dosing tank/effluent pump installations are available in our office.The electrical
<br /> wiring to the pump and alarm in the dosing tank,the wiring in the trench and the connections in the structure must be done
<br /> under a Marion County Electrical Permit.
<br /> Specific Requirements
<br /> Please refer to the Site Evaluation Worksheet which shows the approved areas and other details of the site visit.
<br /> Additional Conditions of Site Approval
<br /> 1. This site is approved for the type of disposal system described above. Peak sewage flow into the systeis limited to a
<br /> maximum of 450 gallons per day,with an average sewage flow of not more than 225 gallons per day. This im s normally
<br /> sufficient to serve a residence with 4(four)bedrooms. Premature failure of the treatment system may occur if either of
<br /> these flow quantities is exceeded. If,for some reason,you expect your water use may exceed these flows, it may be
<br /> advisable to increase the size of the treatment system.
<br /> 2. Any alteration of natural soil conditions(i.e. cutting,tilling, logging, or filling)in the acceptable area may void this
<br /> approval.
<br /> 3. Both the initial and replacement disposal areas are to be protected from traffic, livestock and farming activities,
<br /> development or other potential disturbance of natural soil conditions.
<br /> 4. The area must not be subjected to excessive saturation due to,but not limited to, artificial drainage of ground surfaces,
<br /> roads,driveways and building down spouts.
<br /> 5. This approval is given on the basis that the parcel described above will not be further partitioned or subdivided.
<br /> 6. Placement of a well within 100 feet of the approved areas may invalidate this approval.
<br /> Request for Site Evaluation Report Review or Request for Variance
