2015 NPDES System If at all possible will add soil absorption after system.

2015 System Design Seneca county PSWT=12” and in situ soil=8” New rules allow many more options for Replacement systems 3701-29-10(B)(5)- Provide app. Installation and operation costs of feasible STS options to assist the owner in selection of the STS design. Example 1- SICL Grade 2 PSWT= 10” .4/.6 and 2.4 HLLR Option 1- ATU w/chambers 360/.6= 600x1.25= 750 ft2 360/2.4= 150x.80= 120ft 2 ft trench 3 runs at 124ft (Field 14 ft wide) 3 ft trench 2 runs at 124ft (Field 10 ft wide) sand fill

2015 System Design Example 1- SICL Grade 2 PSWT= 10” .4/.6 and 2.4 HLLR Option 2- LPP w/ chambers 360/.4= 900 x 0.75=675 ft2 360/2.4= 150x 0.70= 105ft 2 ft trench 3 runs at 112ft (Field 14ft wide) 3 ft trench 2 runs at 112ft (Field 10ft wide) sand fill 3 ft trench with 3 zones- 3 runs at 76ft (Field 15 ft wide) Option 3- Engineered Drainage w/leachfield= PSWT= 16” 360/.4= 900x1.25= 1125 w/ chambers= 844 ft2 360/2.4= 150x 0.80= 120 ft. long Blount soils= Drain 4.6 ft deep spaced 22 ft apart

2015 45 ft 128 ft

2015 Site Drainage – 3701-29-16 Engineered drainage Utilizes soil types to develop drain spacing and drain depth to achieve desired PSWT. OSU used Drainmod to simulate 66 soil types Drainage 6ft from up slope and 8ft remaining Max 2” into restrictive layer as determined in soil evaluation. Pipe 4” slotted Slope at least 0.10 per 100ft. Min. of 10” stone and trench width not specified. Lift station can be used if fall not available.

2015 Operation and Maintenance All homeowners are required to purchase operational permit when purchasing an installation permit. New fee for 2016. $125 for all Operational permit and is good for 5 years. Service contracts required on NPDES and ATU 3701-29-09 (I)(2) Registered service providers are required when system is utilizing depth credits (Mounds, LPP, Engineered drainage). Homeowners can only do inspections on gravity leachfields without becoming a registered service provider. If using ATU service provider must do service on entire system

2015 Septic Haulers Will not have inspection day at Fairgrounds. Instead setup time and days on individual basis. Will accept truck inspections from other counties Ensure the Pumping Report is filled out completely. Turn in reports no later than 2nd week of following month If pumping is required by SCGHD we need pumping report regardless if tank is pumped or not.
