Vuecrest Dr. Union, WA 98592 June 7,2023 Mason County Department of Health Services 415N6thSt Shelton,WA 98584 RE: Bruce Stokes Property(Parcel#22230-23-00120)Septic Replacement/Upgrade Dear Inspector: Attached is a replacement/upgrade septic design for a property located at 11181 E State Route 106,Union,WA 98592. The 2-bedroom home was built in 1963 and there is an existing gravity trench septic system assumed to be of the same era. The tanks is a 750-gallon single compartment and the exact size and location of the drainfield is unknown. The septic has been having issues for many years and recent pumpers reports show a high effluent level in the tank and indicate the drainfield is no longer taking water. This is a very limited use property but the owner would like to get the septic upgraded to a modern system so it can be used more often. The existing tank is to be removed and the old drainfield is to be abandoned. The proposed 2-bedroom replacement system will include a new NuWater BNR-500 aerobic treatment unit tank,followed by a 1,000- gallon pump chamber. The proposed replacement drainfield is 300 s.f. of shallow pressure bed. We are also proposing a new control panel with a timer,elapse meter and event counter to extend the life of the system and to facilitate future operation and maintenance. A Notice of Operation and Maintenance of On-Site Sewage System has previously been filed on the property deed. This system meets Table IX repair standards with the new proposed drainfield being less than 25' to the bulkhead,treatment level B without disinfection,and 24"+vertical separation. The property water source is from a spring on the opposite side of the highway and there are no known wells nearby. The property owner's contact information is as follows: Bruce Stokes 25008 Green Mill Ave Santa Clara,CA 91321 (661)714-2676 If you need further information,please contact my office at(360) 898-2255.

Install trench bottoms level. 3. Install locator tape or rebar at each end of all drainfield laterals. 4. Install observation ports as indicated on the plot plan. One required at distal end of each lateral in drainfield with bottom extending to the drainrock/native soil interface. Glue "T" to bottom so Observation Port cannot be easily removed from ground. Install removable cap on top of port at final grade level. 5. Install drainfield during dry weather and soil conditions; any soil smearing must be eliminated by hand raking. 6. Install threaded clean-outs at the end of all laterals (cap must extend to within six inches of finished grade and be marked with locator tape or rebar). 7. Install audio/visual high water level alarm. Redundant off switch not required. 8. Install check valve in pump outlet line to prevent system from draining back into the pump chamber. 9. Tee to Tee construction between laterals and manifold with orifices oriented at 6 o'clock. Install laterals to the manifold with the orifices at 12 o'clock, (do not glue), after pressure test and Environmental Health Dept. approval, turn orifices down (6 o'clock) and glue laterals to manifold. Orifice shields may be used with orifices in the 12 o'clock position in lieu of turning the orifices down to the 6 o'clock position. 10. Filter fabric required over drain rock prior to back filling. If the drain rock extends above natural grade, run the filter fabric at least 2 inches down the trench wall. 11. Encase all water lines within 10' of drainfield and under any driveway/parking areas. 12. Divert all storm water runoff away from on-site sewage system. 13. No curtain drains allowed within 10' of the up-slope edge or 30' of the down-slope edge of the drainfield and reserve area. 14. No vehicular traffic over drainfield area. 15. Inspect floats, clean filters, and test high water level alarm every 6-12 months as needed. 16. All materials and workmanship must meet County and State regulations. 17. Deviation from this design without prior approval from the Designer and Mason County Environmental Health Department will make this design null and void. 18. All manhole lids and access, sampling or inspection ports must have locking covers and be located at ground level. 19. All pressure systems with a pump chamber outlet higher than the drainfield must have a 1/8"hole drilled in the discharge pipe above the pump to prevent siphoning. 20. All transport lines under driveways or parking areas must be encased to prevent crushing. 21. Homeowner is responsible for all property lines. 22.
