  2. Common Sense Initiative - Basic Framework • Metal Finishers - agree to work toward a series of “Goals” to reduce their discharges. • Municipality - in return provides regulatory incentives and technical assistance where required. • State- technical and regulatory assistance.

  3. Benefits of Strategic Goals Program • LOCAL POTW- reduced pollutant discharge to POTW- better working relationship with industries- less chance of NPDES violations- less time devoted to SIU permits • PLATERS- less burdensome permit requirements- less time and money devoted to environmental permits- technical assistance available

  4. North Carolina Update • 4 participating POTWs:- Raleigh, Statesville, Charlotte, Gastonia • 8 metal finishers (3 site visits) • Additional incentives - Air quality, power companies, SBA Loans • Stakeholder meeting (June 29) • Industry Workshop (Fall)

  5. Further Information • Division of Pollution Prevention (919) 715-6515 Greg_Newman@p2pays.org • Surface Finishing Industry Council- SFIC Robert McDowell (716) 425-7500 rmcdowel@rochester.infi.net • EPA Scott Dosick (202) 260-9211dosick.scott@epamail.epa.gov

  6. Zero Discharge Project at Powder Coating OperationHankison International, Newport, North Carolina Randy Donley Manufacturing Engineer (252) 726-1011

  7. Hankison International • 265 employees 31,000 square ft facility • Manufactures filter products and refrigerated air dryers

  8. Background • Established 1947 • 1995 Installed new powder coater • Estimated discharge 1,610 gallons per day • Wastewater management options??

  9. Wastewater Management Options • No City Sewer • Off site hauling $0.43 per gallon($173,075 per year) • Evaporation - curing ovens generate 3 million BTUs per day which should evaporate 600 gallons per day

  10. Process Flow

  11. Cleaning Line

  12. Cleaning Line Modifications Float valve Float valve • Advantages • Greater than 90% reduction in water consumption possible • More efficient rinse - film breakdown • Reuse of dragout solution • National survey - 25% usage

  13. BENEFITS Capital Cost = $500 Water Conservation = 217,500 gallons per year (54%) City Water Costs = $1,011 per year ($4.65 per 1000 gallons) Savings on Treatment Costs = $108,576 per year

  14. Ultrafiltration Unit Filtrate 150 gals/shift BENEFITS Capital Cost = $30,000 Water Conservation = 250,000 gallons per year City Water Costs = $1,162 per year Savings on Treatment Costs = $124,800 per year

  15. Evaporation System
