The system consists of a 1000 gallon tank and 375 lineal feet of line,with a curtain drain upslope of the drainfield. The alteration will replace the existing tank and expand the drainfield. Approved Area&System Type An evaluation of thetest holes dug for soil analysis was conducted August 7,2017. The conditions observed during this site evaluation indicate that the area around the evaluated test holes IS CAPABLE of supporting a STANDARD SEPTIC SYSTEM for the ALTERATION and future REPAIR. System plans are approved WITH NOTATIONS. Please refer to the signed approved site plan revision dated February 9,2018. Any deviation from the approved plans must be authorized by this office prior to installation or the permit may be voided. It is 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 church. Peak sewage flow into the system is limited to a maximum of 1125 gallons per day,with an average sewage flow of not more than 563 gallons per day. This is normally sufficient to serve a church with up to 225 in attendance. Premature failure of the treatment system may occur if either of these flow quantities is exceeded. If for some reason you expect your water use may exceed these flows, it is advisable to increase the size of the treatment system. Specific Requirements COMMERCIAL SYSTEMSwith design flow greater than 600 gallons must be constructed in duplex(with two or more alternating pumps),with controls that activate an alarm when one of the pumps malfunctions. A pre-manufactured electrical control panel capable of monitoring pump performance through elapsed-time meters and cycle counters is required. An effluent filter and service access riser is required at the outlet of the septic tank. Service access manhole for the dosing tank must be adequate to construct, install,service and operate the equipment within. Dosing cycle must discharge no more than 20%of projected daily sewage flow each cycle(Maximum dose 260 gallons). A pre-manufactured electrical control panel is required. Elapsed-time meter and cycle counter is required to monitor pump performance. AN EFFLUENT LIFT PUMP WILL BE REQUIREDto 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. 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. TANK RISERS MUST EXTEND TO THE GROUND SURFACE. The tank must be provided with watertight risers extending to the ground surface or above. The riser lids must be gasketed and securely fastened. HEADER PIPE between Distribution Box and drainfield trench must measure a minimum of 4 feet, must be installed level,and bedded on undisturbed earth. THE ATTACHED SEPTIC TANK ABANDONMENT FORMMUST BE COMPLETED AND RETURNED TO OUR OFFICE. The septic system installer must complete and sign the form and attach a copy of the receipt from the septic tank pumping service for pumping the tank. OBSERVE ALL SETBACKS AND SEPARATION DISTANCESas required by the DEQ rules. A copy of the DEQ setback requirements is available in our office and online at http://www.oregon.gov/deq/Residential/Pages/Onsite.aspxunder Rules: Division 71:Table 1. THE APPROVED SEPTIC SYSTEM AREA MUST BE PROTECTEDfrom 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.
