Round up the design flow to the next 50 gpd value. For instance, a 600 gpd design flow will need 2 aerators (600 gal. rounded up to 1000 gal. needs 2 aerators). The aerator box can be installed in two ways. First option is to install the aerator box so that the bo tom of the aerator box is at the same elevation or higher than the top of the ank risers, see Illustration 3. If the site is sloped the aerator box can be buried, upslope from the tanks. Second option is to install the aerator box with the lids o the box and risers at the same elevation. The sides of the aerator box lid must n t be buried. Aerators can be installed up to several hundred feet away from th diffusors. The line between aerator and diffusors must slope toward diffusors. Aesthetic concerns s ould be considered when placing the aerator Place the aerator away fro ii house windows, doors, and areas where peo e t d to congregate, such as pati s areas and barbecues.

There may be a de ire 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 t at would prevent the sand from accessing oxygen from \ the atmosphere. Placing t o much cover will inhibit plant root growth. Because the C-33 sand is sub-surfs a irrigated, grass and other ground cover will grow rapidly, forming a firm pr tective cover over the OSCAR. At the end of the first growing season the C-33 s tnd layer will be as firm as native soil to walk on. Options include: • Landscaping jute mat w th grass seed or ground cover plantings • A thin layer of mineral s it low in organic content (<10% organics) • Thin layer of crushed or washed rock for wind erosion protection. • Thin layer of bark to wo d chips. • Aggregates the size of ri -rap (5-6 inch diameter) can be "placed" on the OSCAR for protection from dee or elk traffic. These larger sized aggregates must be placed, not dropped, on the OSCAR to prevent breakage of piping and other materials. • Wire mess can be install d over the sand to prevent erosion and allow for grass to grow.

Ensure the final grade slopes away from these areas and water doesn't collect on or around them. Use swales, berms, catch basin and tight lines, curtain drains, etc. to divert all waters 15. Curtain drains can be no closer than 10' upgradient and 30' down gradient of the drainfield 16. Exposed restrictive layers, cuts, banks, etc. can be no closer than 50' downhill from the drainfield. 17. Install access risers on all tanks, valve box and ends of laterals. 18. Make sure septic tank risers are epoxied or caulked to cast in riser rings on tank. 19. Lids must form a water and gas tight seal with the access risers. 20. This system must be installed by a Mason County Certified installer. 21. Deviation from this design without prior approval from the designer and Mason County Health Department will make this design null and void. 22. This design was sized per Washington Administrative CodeWAC246-272A-0230. The operating capacity is based on 45 gallons per day per capita with two persons p bedroom. The minimum design flow per bedroom per day is the operating cap of ninety gallons multiplied by 1.33. This results in a minimum design flow of o_ un ed twenty gallons per day. This creates a surge factor of 33% but anticipated is y gallons per bedroom per day. EXPIRE5:05/t0l `T11'' S stem Owner Responsibilities: 1.
