  1. Northampton Generating Company, L.P.Northampton, PA Electricity Generation and Land Reclamation

  2. Northampton Generating Plant

  3. Project Benefits Generate electricity for 110,000 homesPrinciple fuel is anthracite waste coal (culm) Advanced coal burning technology (CFB)Cleaner energy with low emissionsOperations conducted inside buildingsReclamation of abandoned mine sites

  4. Rebirth of Atlas Cement Site (construction incorporated existing Atlas buildings)

  5. Fuel Unloading Inside Fuel Building

  6. Fuel Handling Inside Fuel Building (dust collection systems control emissions)

  7. Fuel Capabilities Facility Designed to Burn 7,000 Btu/lb Material Primary Fuel is Culm (Anthracite Waste Coal)Transition and Startup Fuel is PropaneCapable of Burning Solid Alternative FuelsFuels Fed via Conveyors to Silo or Blown into BoilerFuels Limited by Air (Stack) and Waste Permits (Ash)Fuels Limited by Borough of Northampton ResolutionNOT Capable of Burning Liquid Fuels (e.g. Oils)NOT a TSDF for Hazardous WasteNOT an Incinerator or Trash Burner

  8. Permitted Fuels(Actual 2006 numbers in parenthesis) Co-firing of Alternative Fuels w/CulmTotal Charging Rate = 105 TPH - (102 TPH) Minimum % of Fuel Mix = 50% Culm - (76% Culm) Coal (anthracite or bituminous) = 15 TPH - (0 TPH)Petroleum Coke = 32 TPH - (11 TPH) Paper Processing Residue = 25 TPH - (6 TPH)Virgin Wood Chips = 20 TPH - (0 TPH)High Carbon Ash = 50 TPH - (4 TPH)TDF (Pending Approval) = 23 TPH - (4 TPH)Propane = as needed for Start-up and Transitions

  9. 2006 Fuel Consumption Total Solid Fuel = 813,651 tonsTotal Ash = 474,820 tonsCulm = 742,951 tons Coal (anthracite or bituminous) = 0 tonsPetroleum Coke = 23,939 tonsPaper Processing Residue = 37,522 tonsVirgin Wood Chips = 0 tonsHigh Carbon Ash = 6,266 tonsTDF = 2,972 tonsPropane = 260,682 gallons

  10. Control Room manned 24/7

  11. Air Emissions Continuously Monitored/Controlled

  12. NGC Plant Emissions Comparison

  13. CFB Operation (Circulating Fluidized Bed) CFB technology known for fuel flexibilityFuel suspended on cushion of air in boilerCombustion occurs at 1,400-1,700 deg FFuel and ash re-circulated using cyclonesAchieves higher combustion efficiencyResults in lower stack emissions Limestone injected w/fuel to reduce SOxAmmonia injected into CFB to control NOxBaghouse filters capture 99.9% of particulates

  14. Truck Proceeding to Enter Building for Ash Loading

  15. Limitations on Ash Beneficial Use Permit – WMGR068“The following carbonaceous wastes: petroleum coke, uncontaminated, untreated wood chips and other paper and wood industry wastes comprised primarily of wood fibers: and the ash generated from the burning of that waste.”Limits on As, Cd, Cr, Cu, Pb, Mn, Ni, Se, ZiSurface Mining Permits – Mod 25Coal and Ash Leachate AnalysisMaximum Acceptable Leachate ConcentrationsLimits on 17 metals, sulfate, chloride, and pH

  16. Ash Trucks Washed after Loading prior to leaving plant

  17. Northampton Fuel Supply Company (located in Scranton/Wilkes-Barre Area)

  18. Culm Removed and Ash Returned

  19. Top Soil used for Cover

  20. Kaminski Site Before and After

  21. Huber Site Before and After

  22. Project Environmental Awards 1996 PA Governor's Award for Environmental ExcellenceConstruction of plant on brownfield site using advanced technology1998 PA Governor's Award for Environmental ExcellenceReclamation of 117 Acres @ Kaminski Site1998 DOI National Award for Excellence in ReclamationReclamation of 117 Acres @ Kaminski Site
