There is an existing 3-bedroom home built in 1968.The house has an existing gravity septic system of the same era. At service visits in August-2020 and July-2023 it was found that condition, full the draiade is needed.nld was not taking water the way it should. Because of the septic system's age an The existing tank is to be decommissioned or removed and the old drainfield is to be abandoned. The proposed 3-bedroom replacement system will be an OSCAR XO2 and will include a new 1,000-gallon 2-compartment treatment tank,followed by a 1,000-gallon minimum 2-compartment discharge tank. The proposed replacement drainfield is 360 s.f. of OSCAR at-grade drip drainfield, sized using an application rate of 1.0 in a Type 1 very gravelly coarse sand. The OSCAR mound is to be dug into the ground and installed flush with the original grade. This will protect it from foot traffic and erosion as it is right next to the existing bulkhead. There will also be a new control panel with a timer,elapse meter and event counter to facilitate future operation and maintenance. This system meets Table IX repair standards with the new proposed drainfield being less than 25' to the bulkhead in Type 1 soil,treatment level A without disinfection, and 24"vertical separation. The property is on a water system and there are no known wells nearby. The property owner's contact information is as follows: Linda Milam PO Box 720 Denair,CA 95316 (209)480-0880 If you need further information,please contact my office at(360) 898-2255.

The intent is not to have too much additional cover over the final C-33 sand layer. Placing too much cover will inhibit plant root growth. Because the C-33 sand is sub-surface irrigated,grass and other ground cover will grow rapidly, forming a firm protective cover over the OSCAR. At the end of the first growing season the C-33 sand layer will be as firm as native soil to walk on. Cover Options include: • Landscaping jute mat with grass seed or ground cover plantings • Thin layer of mineral soil low in organic content(<10% organics) • Thin layer of crushed or washed rock for wind erosion protection • Thin layer of bark or wood chips Do Not Cover C-33 Sand drainfield with: • Organic mix (manufactured top soil from compost) • Filter fabric OSCAR authorized dealer supply kit contact info: • H.D.

Wastewater is collected in the septic chamber where gross solids are separated.The waste stream is aerated in the aeration chambers. Aerated effluent passes though the clarifier then into the pump chamber.The expected waste strength will be 30 mg/I CBODS and 5 mg/I TSS. Effluent is dosed through a 120 mesh disc filter to OSCAR coils, installed in ASTM C-33 sand. Effluent discharged from the coils is treated by the sand prior to infiltrating into the receiving soil. Final discharge is expected to reach 2 mg/I CBOD, 1 mg/I TSS, and 36 FC/100 ml of effluent, meeting Treatment Level A.The X02 tanks can only be used with OSCAR coils.

An OSCAR-X02 is two technologies combined together as one. The system can be designed in increments of flow up to 3500 gallons per day. The OSCAR has different sizing criteria than the X02. The X02 is designed in increments ranging from 500, 750, 1125, 2250, 3,000, to 3,500 gallons per day (see Table 1-2). The OSCAR is designed in increments of 62.5 or 125 gallons per coil per day, depending on coil model (see Tables 2 and 3). Consequently, a design for a 7 bedroom system z (840 gpd) would incorporate a 1125 gallon per day X02 plus 14 0S-50 OSCAR coils (875 gpd). d X02: Treatment Tank: The partition wall between the first and second compartment of the treatment tank must have a 4 inch by-pass hole or the bottom of the tee baffle located between 40% to 60% of the liquid depth. Discharge Tank: The patrician between the first and second compartment of the discharge tank must have a 4 inch by-pass hole located at least 18 inches above the floor of the tank and no more than 27 inches between the bottom of the by-pass hole and floor of the tank. Recommended hight is 18 inches, if possible.

OSCAR X02 Pretreatment s' 3.9 INSTALLATION & MALN'TENANCE 'a PAULA JOY JOHNSON '•. OSCAR At-Grade Drip Distribution Systems - - >' i� ' • 1. Installers must attend OSCAR X02 training and be certified by Dave Lowe at Low Ridge Technologies(www.lowridgetech.com)prior to installing this system. 2. Installer must review OSCAR X02 installer manual prior to system installation. 3. OSCAR X02 supply kits are available through LowRidge Technologies approved suppliers only. 4. The Treatment Tank and Discharge Tank must both be 2-compartment, State approved and sized per the OSCAR X02 manual and the onsite wastewater treatment system designer. 5. OSCAR Sand media must meet or exceed ASTM C-33 standards. 6. Install drainfield level with contour of the ground. 7. Install drainfield during dry weather and soil conditions;any soil smearing must be eliminated by hand raking. 8. Tanks must have risers to the surface as required by Mason County to ensure easy access for future operation and maintenance. 9. Headworks must be in boxes accessible from the surface for future operation and maintenance. 10. Ensure any trees and shrubs are removed,grass is cut short and then scarify surface of ground in drainfield area to prep for drainfield. 11. Ensure 6"minimum cover sand media over the drip irrigation tubing. 12. Install audio/visual high-water level alarm. Redundant off switch not required. 13. Flow inducer tube or block are not required for the pump, it can sit on bottom of tank. 14. Install return line from headworks back into the tee outside the inlet of the treatment tank. 15. Encase all water lines within 10' of drainfield and under any driveway/parking areas. 16. Divert all storm water runoff and house downspouts away from on-site sewage system. 17. No curtain drains allowed within 10' of the up-slope edge or 30' of the down-slope edge of the drainfield and reserve area. 18. Inspect floats, clean filters, and test high water level alarm every 6-12 months as needed. 19. All materials and workmanship must meet County and State regulations. 20. Deviation from this design without prior approval from the Designer and Mason County Environmental Health Department will make this design null and void. 21. All manhole lids and access, sampling or inspection ports must have locking covers and be located at ground level. 22.

The drainfield is to be protected from all vehicle traffic or other damaging factors that could compact or disturb the soils. 25. The preferable cover planting for subsurface drip is turf or grass, or non-invasive groundcover plants. It is recommended to install an optional jute mat upon completion of the drainfield to prevent erosion and then seed with grass immediately. Other options include a thin layer of mineral soil low in organic content(<10% organics) and grass, a thin layer of crushed or washed rock for wind erosion protection, or a thin layer of bark or wood chips. 26. Do not cover the drainfield with organic mix (manufactured topsoil from compost)or filter fabric. 27. The homeowner should ensure no vehicle traffic, roto-tilling or digging in the area of the drip field to prevent damage to the drip tubing. Also, invasive plant species should not be allowed. 28. Home/property owner is responsible for all property lines, corners, surveys, encroachments, etc. 29.
