September 15, 1992 APPLICART~ EL~R cHAS~ Your sit~ has been found suitable for a STANDP~D ON-SIT~ ~WAGE DISPOSAL SYSTEH. The following construction s~eci~ications shall apply to the installa- tion of your septic system. 1. The septic tank shall have a minimum liquid capacity of 1009 gallons. 2. The projected daily sewage flow for this project is calculated at ~50 qallon~ ~ dav. Based on soil conditions observed on this site, the disDosal field will be sized at .~50 linea)~f~et Der 150 ~allons of projected daily sewage flow. A minimum of ~5.0 lineal feet of disposal field will be reqlired for your proposed develop- ment. The disposal ~=enches are constructad two (2) feet wide and on minimum ten (10} foot centers and with no line ex~ding 12~ feet in length. The trenches and perforated pipe are installed level (~l") and contoured to follow the natural ground surface. 3. The disposal field shall be ccnst~eted with ~ial distribut~o~ with a minimum trench depth of 24 inc~e~ and a maximum treneh depth of ~.Q inches. There must be at least 12 inches of backfill over the top of the gravel, measured from the natural ground surface. A groundwater interceptor is =eq~ired as pa~ of this system. This interceptor trench must be constructed a minimu~n twelve (12) inohe~ wide by 42 inches deep with 36 inches of clean gravel placed over a four (4) inch smooth wall perforated pipe~ The interceptor must be located at least ten (10) feet upslope frem the d£s~sal field and must discharge through a watertight~ non- p~rforated pipe beside or b~lew the disposal field. A separation Of 25 feet is reqUired from the septic tank if the tank is louated upslo~ of the groundwa- ter intercepter. An effluent lift pump may be necessary to construct the disposal field in the approved area and at the correct depth. This approval is site specific to :he area tested and the septic system mupt be located in the immediate area of the test pits unless otherwise rized by this office. A new site evaluation may be reqUired if the syst~ is proposed for a diffeFent area on the property. SPECIAL ~ONDITION$: The existing lower soil test pit is dug too close to ~he downslope road cut and ditch. Also, too close to the proposed well. The draiufields will need to be shifted fa=ther upslope and the well will need ~0 be relocated or eliminated altc~ethe~ and the residence serviced from an offsite water ~pply. Refer to the enclose~ setback list which outlines minimum separation distances between eomponents of the septic systems a~d othe~ features~ existing and proposed. The new lot lines must me~t a ten (10} feet mini~az~ setback from the existin~ adjacent drainfi~ld and the replacement drainfield sites. A prec0nStruCtion field stakeout is recommended. Refer to the enclosed stakeout procedure to complete the stakeout. ~ZL A V~LID PERmiT ~ ~ ISSI~,,BY T~I~
