Basal Area:
The basa area is comprised of the total area where the C-33 sand media is

by dividing the design flow rate by the soil loading rate specified in WAC 246-272A
(local codes may have differing loading rates). F s r _ \W

***Table 1-2 is a quick reference guide.
..*_AZ Aerator:.
For each!500 gpd design flow one aerator will be needed. Round up the
design flow to the next 500 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 must be installed so that the bottom of the aerator box is
at the same eleMation or higher than the top of the tank risers, see Illustration 3.
If the site is sloped the aerator box can be buried, upslope from the tanks. The
sides of the aerator box lid must not be buried. Aerators can be installed up to
several hundred feet away from the diffusors. The line between aerator and
diffusors must slope toward diffusors.
Aesthetic concerns should be considered when placing the aerator box.
Place the aerator away from house windows, doors, and areas where people to d
to congregate, such as patios areas and barbecues.

OSCAR Cover Options. MASON COUNTY ENVIRONMENTAL HEALTH
DJA
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 that would prevent the sand from accessing oxygen from
the atmosphere: Placing too much cover will inhibit plant root growth. Because
the C-33 sand issub-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.
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.
• Aggregates the size of rip-rap (5-6 inch diameter) can be "placed" on the OSCAR
for protection from deer 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 installed over the sand to prevent erosion and allow for grass
to grow.
Do Not Cover C-33 Sand with:
• organic mix (manufactured top soil from compost) •
• filter fabric •

Installation Notes
Oscar-X02 Treatment System
20 E Tyler Lane 32132-22-90051
1. 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.
2. This is a repair for a three bedroom. system with install approval in 1980. New
septic tank was installed in 2005. Residence does not have a foundation. We dug a
few soil logs and they had water at 6".We dug two soil logs by the mobile home and
had 24". I checked them a week later and they were still dry.We are installing four
bedroom drainfield. Original system is in the fron yard. We do not have adequate
room for a new drainfield. Power lines and limited room.
3. Installer responsible to contact designer prior to installation.
4. Installer responsible to submit installation form to designer with a plot map, tank
information; pump information and any changes from the original design.
5. Oscar drainfield: ASTM C-33 sand media as per Washington Department of Health's
Recommended Standards and Guidance for Intermittent Sand Filter.
6. Minimum of 6" of sand throughout out the lateral(coil) area, must be level.
7. Oscar X02 parts list on Page 11
8. Controls to be set per XO2 guidelines
9. Septic tank location must meet all required setbacks.
10. Keep wheeled vehicles off the drainfield area before, during and after installation.
11. Tracked equipment only
12. ,All ground, surface water and roof drains must be diverted away from the septic tanks and
drainfield.
13. 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 d''" rt
all waters
14. Curtain drains can be no closer than 10' upgradient and 30' down gradient of the. •airtfRig
15. Exposed restrictive layers, cuts, banks, etc. can be no closer than 50' downhill �` af
drainfield. . _ ".416. Install access risers on all tanks, valve box and ends of laterals. yam ,r-,,, �
17. Make sure septic tank risers are epoxied or caulked to cast in riser rings o ank., <• ••-.; :s.
18. Lids must form a water and gas tight seal with the access risers. .c
19. This system must be installed by a Mason County Certified installer.
20. Deviation from this design without prior approval from the designer and Mason County
Health Department will make this design null and void.
21. 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 per
bedroom. The minimum design flow per bedroom per day is the operating capacity of
ninety gallons multiplied by 1.33. This results in a minimum design flow of one hundred
twenty gallons per day. This creates a surge factor of 33% but anticipated flow is ninety
gallons per bedroom per day.

System Owner Responsibilities:
1. Owner or'installer responsible for payment of installation permit prior to starting
