12 WPCP Treatment Process Cleans wastewater by removing impurities before discharge to river/lake. Cleans wastewater by removing impurities before discharge to river/lake. Removed impurities become sludge or residuals. Removed impurities become sludge or residuals. Residuals must be properly disposed or treated for reuse.

13 History 1986 – 2001: Composting 1986 – 2001: Composting 2002: Landfilling/Canadian Composting 2002: Landfilling/Canadian Composting 2003 – 2005: N-Viro Alkaline Treatment 2003 – 2005: N-Viro Alkaline Treatment 2005 – Present: Canadian Composting Franklin County, Coventry, VT 2005 – Present: Canadian Composting Franklin County, Coventry, VT Wherever we could Wherever we could

14 Last Few Years: Landfilling Got shut out of Canadian sites.

15 Landfilling Not reliable. Not reliable. Not sustainable. Not sustainable. Not “green”. Not “green”. More expensive More expensive

16 Landfilling is not reliable DEC could prohibit it. DEC could prohibit it. Landfills could refuse it. Landfills could refuse it.

17 Risks Violations Violations Fines Fines Environmental harm Environmental harm More expensive alternatives More expensive alternatives

18 Need a reliable and affordable alternative that we can control.

19 Composting Have permits Have permits Effective Effective Expensive to run Expensive to run Difficult to control odors Difficult to control odors Fires/Time – Substantial effort and expense to get running again Fires/Time – Substantial effort and expense to get running again

20 There’s a Better Way ALKALINE TREATMENT ALKALINE TREATMENT More reliable More reliable Less expensive Less expensive Easier to control odors Easier to control odors

21 Request to DEC Allow use of the less expensive more reliable Alkaline Treatment. Allow use of the less expensive more reliable Alkaline Treatment. 70% reduced rate of 40 tpd. 70% reduced rate of 40 tpd.

22 Multi Step Decision Making 1. Obtain Permits? 2. Buy Equipment? 3. Operate during emergencies? 4. Operate more often? We’re midway in Step 1.

23 Step 1 Permit Process 1. Perform Engineering 2. Make Initial Application 3. Go through Environmental Review and Public Comment 4. Address public/regulatory comments 5. Complete Permit Application 6. DEC Acts on Application

24 Multi Step Decision Making 1.

Buy Equipment? 3. Operate during emergencies? 4. Operate more often?

25 What is Alkaline Treatment? Not composting – biological Not composting – biological Not incineration – combustion Not incineration – combustion It is a chemical process It is a chemical process

26 Residuals are combined with alkaline materials Lime Lime Lime Kiln Dust Lime Kiln Dust Cement Kiln Dust Cement Kiln Dust Wood Ash Wood Ash Coal Ash Coal Ash

27 Chemical Reaction Generates heat to destroy pathogens Generates heat to destroy pathogens Raises pH over 12 to stabilize Raises pH over 12 to stabilize Dries for easy handling Dries for easy handling

32 Why AT? Easy O&M Easy O&M Easier odor control Easier odor control Low capital cost Low capital cost Low operational cost Low operational cost Fast – 72 hours Fast – 72 hours Effective Effective Marketable product Marketable product

33 How are odors controlled? Source Control Source Control Containment Containment –Delivery, mixing, stockpiling, product storage all indoors Air Collected Air Collected Air Diluted with 440,000 cfm fan Air Diluted with 440,000 cfm fan Discharged up 117’ stack for dispersion Discharged up 117’ stack for dispersion Should be no off site odors Should be no off site odors

34 Can you guarantee no odors? Wish we could Wish we could We know there should be no off site odors We know there should be no off site odors We also know that things happen We also know that things happen If there are odors, it means something has gone wrong and we need to know about it right away. If there are odors, it means something has gone wrong and we need to know about it right away. 24 hour hotline and response plan 24 hour hotline and response plan

35 We will respond immediately We will respond immediately We will fix any problems We will fix any problems Otherwise, we will shut down the process Otherwise, we will shut down the process

36 How different from before? 70% less residuals 70% less residuals Compatible residuals (fresh, treated) Compatible residuals (fresh, treated) Odor control chemical added at WPCP Odor control chemical added at WPCP All processing and storage indoors All processing and storage indoors City control of operation City control of operation

37 What if run out of room for indoor product storage? SHUT DOWN OPERATION SHUT DOWN OPERATION

38 What is product used for? Making top soil Making top soil Adjusting soil pH Adjusting soil pH Improving soil Improving soil –Adds organic matter –Adds N, P, K

39 How do we know product is safe? Meets EPA and DEC Regulations for disinfection Meets EPA and DEC Regulations for disinfection Class A/EQ Material Class A/EQ Material Residuals tested on a regular basis Residuals tested on a regular basis Ingredients tested Ingredients tested –Prior to source approval –Periodically thereafter Rigorous product testing Rigorous product testing –Every day for weekly composite –Includes metals and pathogens

40 Financial Landfilling: $65/ton; $450,000/year Landfilling: $65/ton; $450,000/year If can’t landfill: If can’t landfill: –Fines for non-compliance? –$110 T&D = $715,000/yr ($265,000 more) AT: $30 - $55/ton AT: $30 - $55/ton Saves $100,000 to $250,000 /yr Saves $100,000 to $250,000 /yr
