Please call me at (360) 427-9670, ext. 353 if you have any questions. Sincerely, 0 Cindy Waite l0+ Environmental Health Mason County Public Health COMMENTS: Soil logs were 0-12" silt loam. You will need to go through winter observations prior to system approval or find a different location. Soil logs must be dug to specifications, not a post hole. Area of proposed drainfield had wetland plants and maybe standing water during the winter.

I inspected the site yesterday(1/24) and found some concerns. I contacted Paula, who was close by and we were able to inspect together. A summary of our findings are below. The proposed drainfield area was very limited on this site. We had met on 1/4/18 and came up with a small area of possibility and to proceed with a curtain drain and winter observation. The proposed curtain drain was not installed in the location and orientation as we previously discussed. Soils were also disturbed with cutting and filling within the drainfield area. The ob ports appear to be installed in fill. Ob. port 1 had water at surface(0"). Ob. port 2 had water at 17" but appeared to be installed in 12"+/-of fill. Based on these findings I can no longer support a system in this area. I understand this has been a frustrating experience for you and I have tried to accommodate and assist where I can. Paula and I spent a good amount of time yesterday walking the property and neighboring properties that Paula thought you owned as well. With the amount of streams/drainages around and on these properties,It was difficult to find a new direction. Our suggestion is to spend some more time exploring soils that are 75-100ft+ from surface waters and over 12"to a restrictive layer. Are there any neighboring properties willing to grant easements? Most of all,I suggest not putting any additional machinery on the property unless they are certified septic professionals/designers involved. This is not an easy property for septic obviously and our end goal is to have a system that functions properly for many years,through all seasons. With limited soils and the disturbance from clearing thats taken place its left very limited options. I am in support of a partial refund on the winter observation, as I see no point in proceeding with it in the area proposed. I have attached the Refund Request form if you are interested. If we can be any more assistance please let us know and I do apologize for not having better news. Any further questions let me know. - - Alex Paysse Environmental Health Specialist III 360.427.9670-extension 279 Mason County Community Services 415 N. 6th Street-Shelton, WA 98584 www.co.mason.wa.us/health >>>james allman <geoduck22@gmail.com> 1/10/201811:19 AM >>> I am trying really hard to get the curtain drain put in the excavator guy schedule isn't working out too good will probably be down there tomorrow in the rain storm plan on coming in to get the winter watch permit Friday or Monday file:///C:/Users/alexp/AppData/Local/Temp/XPgrpwise/5A69B52DMasomnai11001763475... 2/15/2018 Page 2 of 2 On Dec 21,2017 4:45 PM, "Alex Paysse" <alexo@co.mason.wa.us> wrote: 930am on the 4th.See you then - - Alex Paysse Environmental Health Specialist III 360.427.9670-extension 279 Mason County Community Services 415 N. 6th Street-Shelton WA 98584 www.co.mosonma.uslhealth >>>James allman <geoduck220amail.com> 12/21/20174:44 PM >>> I'll make sure I'm there,give me approx time.thanks On Dec 21,2017 3:08 PM, "Alex Paysse" <alexo@co.mason.wa.us> wrote: Jamie, I can reinspect a new hole,however it will not be until after the 1st.Can Ijust stop by or do you need an appointment?I am open on the 4th. - - Alex Paysse Environmental Health Specialist III 360.427.9670-extension 279 Mason County Community Services 415 N 61h Street-Shelton.

Preliminary Activities A wet season monitoring program will be conducted after completion of the appropriate application form and payment of fees. The fees are based on whether the monitoring was performed by Mason County Public Health(6 inspections)or by a licensed designer(with 3 quality assurance inspections by Mason County Public Health.) If a licensed designer will be conducting the monitoring program,a site specific monitoring plan will be submitted by the designer as part of the overall system design. 2. Site Preparation A minimum of 2 observation ports will be installed in locations representative of a cross section of the proposed drainfield area. Recommended monitoring port design will consist of a vertically oriented section of 4 inch diameter perforated pipe,wrapped in filter fabric and bedded in clean,washed drainrock or pea-gravel that has been backfilled into a 12-24 inch test hole. The drainpipe should be capped and flagged so as to be easily visible to Public Health staff. 3. Observations and Presentation of Findings Wet season observations will take place during the months of January through March. The frequency and timing of observations will be dependent on site characteristics and on rainfall characteristics that occur during the monitoring period. The designer will submit a minimum of 6 observations along with the NCDC rainfall data for the area during the period of January through March (bU[ //www.ncdc.nom.gov/oa/mpt)/freedata.html). Observations will be recorded with the date and time of the observation and the depth of the water in the pipe. 4. Analysis of Findings Monitoring results will not be considered valid when the rainfall for the period of observation did not exceed 80%of the 10 year average rainfall for the area during the 6-month period of October through March. 5.

LOWeFlow Treatment 7. INSTALLATION& MAINTENANCE PAULA JOY JONNSON' LICWar[SriEsf Nt:tt ±l. OSCAR At-Grade Drip Distribution Systems EMASS csSd 1. Installers must attend LOWeFlow—OSCAR training and be certified by Dave Lowe at Low Ridge Technologies(www.lowridgetech.com)prior to installing this system. 2. LOWeFLOW—OSCAR supply kits are available through H.D. Fowler,contact Dennis Groff,phone: 1 (800) 927-5699 and controls will be programed by H.D. Fowler. 3. Install drainfield level with contour of the ground. 4. Install drainfield during dry weather and soil conditions; any soil smearing must be eliminated by hand raking. 5. Tanks must have risers to the surface as required by Mason County to ensure easy access for future operation and maintenance. 6. Headworks must be in boxes accessible from the surface for future operation and maintenance. 7. Ensure any trees and shrubs are removed,grass is cut short and then scarify surface of ground in drainfield area to prep for drainfield. 8. Ensure 6"minimum cover ASTM C-33 sand over the drip irrigation tubing. 9. Both pump lines must have a one-way check valve installed to keep the supply line charged in between doses. 10. LOWeFLOW gravel filter is to be installed at an elevation that it can gravity-drain back into the recirculation tank. 11. Encase all water lines within 10' of drainfield and under any driveway/parking areas. 12. Divert all storm water runoff and house downspouts 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.Inspect floats, clean filters,and test high water level alarm every 6-12 months as needed. 15.All materials and workmanship must meet County and State regulations. 16.Deviation from this design without prior approval from the Designer and Mason County Environmental Health Department will make this design null and void. 17. All manhole lids and access, sampling or inspection ports must have locking covers and be located at ground level. 18. All transport lines under driveways or parking areas must be encased to prevent crushing. 19. The preferable cover planting for subsurface drip is turf or grass. It is recommended to spread a thin layer of straw upon completion of the drainfield to prevent erosion and then seed with grass immediately. 20. 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. 21. Homeowner is responsible for all property lines. 22. Owner Please Note: When you begin using your septic system, contact your septic installer to discuss setting up a schedule for your required Operation&Maintenance. ,� � � 0� 13
