Septic Permit 555-18-006520-PRMT Page 2 of 3 Datte➢C0r{at�roate Issue(1t31(9/2019 ,: Ty Work 1?escriPtion 3�tNSTAiL F'OR FUTUFW 2$DRM HARDtHIP HOME; k . Gondrtians ofApp�ova[ This property has been approved for a STANDARD SEPTIC SYSTEM in the area identified in Site Evaluation Report 555-17-006749. System plans reflect the approved stakeout and are approved as submitted. Refer to approved plans dated September 14,2018. Any deviation from the approved plans must be authorized by this office prior to installation or the permit may be voided. It's the responsibility of applicant/installer to coordinate these requirements with all others in OAR 340-071-0220. This permit is for a system designed to serve a single family dwelling with a maximum of 4 bedrooms. Peak sewage flow into 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. Premature failure of the treatment system may occur if either of these flow quantities is exceeded. If,for some reason,you expect your domestic household water use may exceed these flows, it is advisable to increase the size of the treatment system. PRESSURE OPERATED EQUAL DISTRIBUTION IS REQUIRED as part of this installation. TRENCH DEPTHS are 18"minimum/20"maximum and require a pressure-operated hydrosplitter to achieve equal distribution. Lines leading from hydrosplitter to distribution boxes must drain freely,with no sag. AN EFFLUENT LIFT PUMP WILL BE REQUIRED to install the septic system disposal field in the approved area and at the required depth. Detailed instructions for dosing tank/effluent pump installations are available in our office. The electrical wiring to the pump and alarm must be installed in accordance with the appropriate Electrical Code. The electrical work must be done under a Marion County Electrical Permit and must be inspected and approved by a Marion County Electrical Inspector. The work must be left uncovered and accessible for inspection. The electrical inspection includes the connections to the pump and alarm in the dosing tank,the wiring in the trench and the connections in the structure. The effluent pipe must have 18-gauge minimum green tracer wire or green metallic tape placed along the line. HEADER PIPE between Distribution Box and drainfield trench must measure a minimum of 4 feet,must be installed level, and bedded on undisturbed earth. TANK RISER: The tank must be installed with watertight risers extending to the ground surface or above. The riser lid must be gasketed and securely fastened. DRY SOIL CONDITIONS ARE REQUIRED FOR INSTALLATION(March 1 —October 31) The geographical area in which the property lies is considered a risk to installation during winter months. Soil moisture conditions generally preclude construction of the drainfield in the winter months. OBSERVE ALL SETBACKS AND SEPARATION DISTANCES as required by the DEQ rules. A copy of the DEQ setback requirements is on file in our office and available online at http://www.oregon.gov/deq/Residential/Pages/Onsite.aspx under Rules: Division 71:Table 1. MAINTAIN PERMANENT ACCESS to septic tank for pumping and service.The septic tank should be pumped and inspected by a licensed septic tank pumping service before sludge and scum accumulations reach 30%of the tank liquid operating volume. Pumping every 3 to 5 years is an average interval. The septic tank is a reservoir for the solid materials in the sewage waste stream. Excessive accumulation of these solid materials in the septic tank will cause the solids to wash out of the tank and into the drainfield. This will cause irreversible damage to the drainfield and will eventually lead to a system failure. THE APPROVED SEPTIC SYSTEM AREA MUST BE PROTECTED from any vehicular traffic, livestock and farming activities. Other activities such as excavating or filling,driveway placement, paving or other similar activities that alter the natural soil conditions will adversely affect the soil and the septic system function and lead to premature system failure. The area must not be subjected to excessive saturation due to artificial drainage of ground surfaces,driveways, building downspouts or other sources. The areas of the initial septic system and the future repair system must both be protected. 3/19/19:10:26:30AM Page 2 of 3 ONS_OnsiteCSC_pr
