  9. Water Pollution Control Plant • City users: residents, businesses, SUNY, GP, Pactiv • Town users plus future growth • County Septage • Other hauled wastes

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

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

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

  13. Landfilling • Not reliable. • Not sustainable. • Not “green”. • More expensive

  14. Landfilling is not reliable • DEC could prohibit it. • Landfills could refuse it.

  15. Risks • Violations • Fines • Environmental harm • More expensive alternatives

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

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

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

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

  20. Multi Step Decision Making • Obtain Permits? • Buy Equipment? • Operate during emergencies? • Operate more often? We’re midway in Step 1.

  21. Step 1 Permit Process • Perform Engineering • Make Initial Application • Go through Environmental Review and Public Comment • Address public/regulatory comments • Complete Permit Application • DEC Acts on Application

  22. Multi Step Decision Making • Obtain Permits • Perform Engineering • Make Initial Application • Go through Environmental Review and Public Comment • Address public/regulatory comments • Complete Permit Application • DEC Acts on Application • Buy Equipment? • Operate during emergencies? • Operate more often?

  23. What is Alkaline Treatment? • Not composting – biological • Not incineration – combustion • It is a chemical process

  24. Residuals are combined with alkaline materials • Lime • Lime Kiln Dust • Cement Kiln Dust • Wood Ash • Coal Ash

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

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

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

  28. Can you guarantee no odors? • Wish we could • We know there should be no off site odors • 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. • 24 hour hotline and response plan

  29. We will respond immediately • We will fix any problems • Otherwise, we will shut down the process

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

  31. What if run out of room for indoor product storage? • SHUT DOWN OPERATION

  32. What is product used for? • Making top soil • Adjusting soil pH • Improving soil • Adds organic matter • Adds N, P, K

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

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