<br /> Approved Area&System Type
<br /> Test pits and other site features were evaluated on June 27,2018. The conditions observed during this site evaluation indicate
<br /> that the area around the test pit is capable of supporting a STANDARD system for the REPAIR. Plans are approved as revised.
<br /> Please refer to the signed approved site plan dated July 10,2018. Any deviation from the approved plans must be authorized
<br /> by this office prior to installation or the permit may be voided. It is the responsibility of applicant/installer to coordinate these
<br /> requirements with all others in OAR 340-071-0220.
<br /> This Permit is for a system designed to serve a single family dwelling with a maximum of 4 bedrooms. Peak sewage flow into
<br /> the system is limited to a maximum of 450 gallons per day,with an average sewage flow of not more than 225 gallons per day.
<br /> Premature failure of the treatment system may occur if either of these flow quantities is exceeded. If,for some reason,you
<br /> expect your domestic household water use may exceed these flows, it is advisable to increase the size of the treatment system.
<br /> Specific Requirements
<br /> TANK RISER: The tank must be installed with watertight risers extending to the ground surface or above. The riser lid must be
<br /> gasketed and securely fastened.
<br /> EFFLUENT SEWER:The effluent sewer is the pipe from the septic tank to the distribution box. The material required is 3034 or
<br /> Schedule 40 pipe with 18-gauge minimum green tracer wire or green metallic tape placed along the pipe. The effluent sewer
<br /> shall extend at least five(5)feet from the tank. There must be a minimum difference of eight(8)inches between the invert(flow
<br /> line)of the septic tank outlet and the invert of the distribution or drop box outlet. In Equal Distribution,there must be six(6)
<br /> inches of fall between the septic tank outlet and the distribution box inlet. In Serial Distribution,there must be two(2)inches of
<br /> fall between the septic tank outlet and the drop box inlet.
<br /> HEADER PIPE between Distribution Box and drainfleld trench must measure a minimum of 4 feet, must be installed level,and
<br /> bedded on undisturbed earth.
<br /> OBSERVE ALL SETBACKS AND SEPARATION DISTANCES as required by the Department of Environmental Quality rules. A
<br /> copy of the DEQ setback requirements is available in our office and online at -
<br /> http://www.oregon.gov/deq/Residential/Pages/Onsite.aspx under Rules: Division 71:Table 1.
<br /> THE APPROVED SEPTIC SYSTEM AREA MUST BE PROTECTED from any vehicular traffic, livestock and farming activities.
<br /> Other activities such as excavating or filling,driveway placement, paving or other similar activities that alter the natural soil
<br /> conditions will adversely affect the soil and the septic system function and lead to premature system failure. The area must not
<br /> be subjected to excessive saturation due to artificial drainage of ground surfaces,driveways, building downspouts or other
<br /> sources. The areas of the initial septic system and the future repair system must both be protected.
<br /> MAINTAIN PERMANENT ACCESS to septic tank for pumping and service.The septic tank should be pumped and inspected by
<br /> a licensed septic tank pumping service before sludge and scum accumulations reach 30%of the tank liquid operating volume.
<br /> Pumping every 3 to 5 years is an average interval. The septic tank is a reservoir for the solid materials in the sewage waste
<br /> stream. Excessive accumulation of these solid materials in the septic tank will cause the solids to wash out of the tank and into
<br /> the drainfield. This will cause irreversible damage to the drainfield and will eventually lead to a system failure.
<br /> Installation of this onsite wastewater treatment system has been determined to comply with the applicable requirements in
<br /> Oregon Administrative Rules Chapter 340, Divisions 071 and 073 and the Conditions of Approval above.
<br /> 1. In accordance with Oregon Revised Statute 454,665,this Certificate of Satisfactory Completion is issued as evidence of

<br /> function indefinitely without failure. Conditions imposed as permit requirements continue for the life of the system.
<br /> 3.The area of the initial and the identified replacement area must not be subjected to activity that is likely to adversely
<br /> affect the soil or the functioning of the system.Such activities may include, but are not limited to,vehicular traffic, livestock,
<br /> covering the area with asphalt or concrete,filling, cutting,or other soil modification activities.
<br /> 4.This onsite wastewater treatment system that be connected to the facility referenced herein within 5 years of the
