N OLICENSED DESI 1A EXPIRES 05'10, Design: The single family residence packages are designated as: OSXOz-240, OSX02-300, OSX02-360, OSX02-450, OSX02-480, and OSX02-600 and have the corresponding design flows of 240, 300, 360, 450, 480, and 600 gallons per day. The OSX02-240, 300, 360, 450, and 480, are standard packages. Design flows greater than 480 gallons per day are considered custom and will require design assistance from Lowridge Onsite Technologies, Inc. For the standard single family residence OSCAR-X02 package parts list see the appendix. The X02 can only be used with OSCAR coils. All tanks must be approved by Washington Department of Health. 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 Ion coil model (see Tables 2 and 3). Consequently, a design for a 7 bedroom system (840 gpd) would incorporate a 1125 gallon per day X02 plus 14 0S-50 OSCAR coils (875 gpd). 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.

There may be a desire to cover the OSCAR with something additional to the specified ASTM C-33 sand. 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. b11(1 PROVE . _ JUN 12 2023 MASON COUNTY ENVIRONMENTAL HEALTH JBW Options include: • landscaping jute mat with grass seed or ground cover plantings • a 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 to wood chips.

Discharge Tank: 4. 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. 5. The prepared site plan is not a survey. It's the owner's responsibility to verify property lines, utility lines (water, sewer, power, phone and gas) prior to installation. 6. Minimum of 6" of sand throughout out the lateral area, must be level. 7. The tanks may be moved as necessary to accommodate building requirements. 8. Septic tank location must meet all required setbacks. 9. Keep wheeled vehicles off the drainfield area before, during and after installation. 10. Tracked equipment only 11. ,All ground, surface water and roof drains must be diverted away from the septic tanks and drainfield. 12. Ensure the final grade slopes away from these areas and water doesn't collect on or around them. Use swates, berms, catch basin and tight lines, curtain drains, etc. to divert all waters 13. Curtain drains can be no closer than 10' upgradient and 30' down gradient of the drainfield 14. Exposed restrictive layers, cuts, banks, etc. can be no closer than 50' downhill from the drainfield. 15. Install access risers on all tanks, valve box and ends of laterals. 16. Make sure septic tank risers are epoxied or caulked to cast in riser rings on tank. 17. Lids must form a water and gas tight seal with the access risers. 18.
