1. Waste Water residuals and land application

2. Tar Heel – a study 3 very different situations
1) Davco – sanitary system
Handled as a liquid sludge to a POTW (publicly owned treatment works – i.e.. A city)
2) Conventional Activated Sludge
Handled as a belt pressed sludge and sent to the public landfill as a beneficial use solid
3) Anaerobic Basins
Handled as a liquid sludge and spread on local farms

3. Davco – plant bathrooms
Generates 40,000 gallons of sludge (liquid) per month on average.
Subject to 503 regulations because of “human” factor
40 CFR 503–Disposal of Sewage Sludge
Domestic sewage biosolids
Want to avoid “503” and stay industrial user

4. Handled by Sewage hauler
Not dewatered – no capacity for belt wash water
Water cannot enter Activated Sludge system
Plant Water Re-use
Handled by local Domestic WWT plant (PWC – Fayetteville NC)

5. Conventional Activated Sludge solids
5MM gallons under aeration
Cannot land apply – 2 windows for Land Application in this area and we generate year round
Installed a 2 meter belt press (BMP)
Average 120,000 gallons of wasted activated sludge per day
Attain working average of 13% solids with peaks in the 15% area

6. Hauler
Utilize our Licensed Land Application hauler to take to local landfill
Get excellent rates based on tonnage
Get excellent rates because it activates their domestic trash in a biogas to energy process that they have going
Not technically recycling – but certainly the next best thing.

7. Opportunities for Land Application
We have looked into land application on non farming sites and there is some opportunity
Financially this is a bad decision
Poundage would go down and lose preferential tipping fees.
Costs would actually go up, even though we were hauling less loads to the landfill
Landfill will NOT adjust because they desire our sludge for activation of domestic trash

8. Anaerobic lagoons Huge storage capacity (15MM gallons each – 2 basins)
Have the ability to hold solids so that we can land apply during the farmer’s “window”
Hauler is able to negotiate excellent pricing because we operate on HIS schedule.

9. Improvements Centrifuge Solids and grease recovery
Huge money generator (1.7MM annually)
Solids have decreased to the degree we will move from twice a year land app to a single event saving an additional $ K per year

10. Interesting facts Hauler is full service
Provides all monitoring and testing
Provides a bound state report at the end of each application year
All farms are permitted to the hauler
2 – 4 Million gallons applied per event

11. Potential issues to consider
We have no permitted fields of our own
Positive – no public hearings, postings, etc with “Smithfield” on them
Negative – we are limited to haulers that provide this service
We are responsible for everything – you CANNOT sign away your responsibilities
Spills
Errors in annual report
