<br /> Under the conditions observed at the above address, an ALTERNATIVE SYSTEM with CAPPING FILL
<br /> DRAINFIELD or GRAVELLESS ABSORPTION METHOD is required by DEQ rules for both the INITIAL and
<br /> FUTURE REPAIR systems. Please refer to the signed approved site plan dated April April 10, 2019.
<br /> Alternative systems include SAND FILTERS, RECIRCULATING GRAVEL FILTERS, and ALTERNATIVE
<br /> TREATMENT TECHNOLOGIES. Alternative systems are installed where soil, drainage,water table levels, or
<br /> space limitations do not allow for a standard system installation. The unit pre-treats the septic tank effluent
<br /> before it is discharged into the ground. The owner of a Sand Filter, RGF or ATT system must maintain a
<br /> service contract with a licensed and certified professional to service and maintain the onsite system.
<br /> A service contract must be entered into before the system is installed and must be maintained until the
<br /> system is decommissioned.
<br /> Specific Requirements
<br /> Please refer to the Soil Notes/Field Worksheet which shows the approved areas and other details of the site
<br /> visit.
<br /> ANTI-BUOYANCY IS REQUIRED for the septic tank. Please refer to manufacturer's specifications as listed
<br /> on the DEQ website regarding approved anti-buoyancy methods.
<br /> AN EFFLUENT LIFT PUMP IS REQUIRED to install the septic system disposal field in the approved area and
<br /> at the required depth. Detailed instructions for dosing tank/effluent pump installations are available in our
<br /> office. The electrical wiring to the pump and alarm in the dosing tank, the wiring in the trench and the
<br /> connections in the structure must be done under a Marion County Electrical Permit.
<br /> GRAVELLESS ABSORPTION TRENCHES ARE ALLOWEDas part of this installation. Hole spacing in the
<br /> pressure distribution piping is 24 inches on center. A minimum 2-foot squirt height is required at the most
<br /> remote orifice. Each line must end with a long sweep elbow and flushing orifice with removable cap at or
<br /> above finished grade. Each pressure lateral must have at least one inspection port with minimum diameter of
<br /> 6 inches. Chamber must be supported by adequate footing and have a barrier to prevent burrowing animals
<br /> from entering the absorption chambers.
<br /> Additional Conditions of Site Approval
<br /> 1. This approval is for a system designed to serve an agricultural business office. Peak sewage flow into the
<br /> system is limited to a maximum of 225 gallons per day, with an average sewage flow of not more than 113
<br /> gallons per day. This is estimated to be sufficient for up to 15 employees. Premature failure of the treatment
<br /> system may occur if either of these flow quantities is exceeded. If, for some reason, you expect your water
<br /> use may exceed these flows, it may be advisable to increase the size of the treatment system.
<br /> 2. Any alteration of natural soil conditions(i.e. cutting or filling) in the acceptable area may void this approval.
<br /> 3. Both the initial and replacement disposal areas are to be protected from traffic, livestock and farming
<br /> activities, development or other potential disturbance of natural soil conditions. The area must not be
<br /> subjected to excessive saturation due to, but not limited to, artificial drainage of ground surfaces, roads,
<br /> driveways and building down spouts.
<br /> 4. This approval is given on the basis that the parcel described above will not be further partitioned or
<br /> subdivided.
<br /> 5. Placement of a well within 100 feet of the approved areas may invalidate this approval.
<br /> CALL BEFORE YOU DIG—ITS THE LAW
<br /> ATTENTION:Oregon law requires you to follow rules adopted by the Oregon Utility Notification Center. Those rules are set forth by Oregon Administration Rules. You may obtain
<br /> copies of the rules by calling the center.(Note:The telephone number for the Oregon Utility Notification Center is 1-800-332-2344.)
