    Director of Environmental Affairs
 The Amalgamated Sugar Company LLC
                Introduction

   In 2002 a PM10 Maintenance Plan was
    developed by IDEQ for the Treasure Valley
    (Boise & Nampa areas).

   The Amalgamated Nampa Facility
    accounted for only ~2% of the PM10
    emissions in the Treasure Valley.

          Purpose of Presentation
   Compare emissions from The Amalgamated
    Sugar Company LLC (TASCO) Idaho
    facilities to:
    • On-Road Mobile Sources
    • Area Sources (Residential heating, agricultural
      activities, etc.)
    • Electric Utilities (Fossil fuel-fired power plants)
    • Determine Amalgamated’s estimated emissions
      relative to other emissions sources.
               Challenges

 Numerous emission inventory databases
  available (State, EPA, Department of
  Energy)
 Accuracy/Reliability of Estimates
  • Difficult to determine
  • Numerous assumptions
  • Important to document assumptions
 Data Availability – Annual Emissions
The Amalgamated Sugar Co. LLC (TASCO)
                  Idaho Facilities


 Three facilities located in the cities of Paul,
  Twin Falls and Nampa.
 Seasonal Operation
  • Beets processed in fall and winter (5-6 million
    ton/yr)
  • Sugar juices processed in spring and summer
 Products
  •   Granulated sugar (over 860,000 ton/yr)
  •   Cattle feed (580,000 ton/yr)
  •   Desugarized molasses (CSB 118,000 ton/yr)
  •   Betaine (29,400 ton/yr)

     TASCO Emission Sources

 Combustion Sources
  • Boilers (Baghouses or Scrubbers)
  • Pulp Dryers (Scrubbers)
  • Lime Kilns (Scrubbers)
 Non-Combustion Sources
  • Material Handling Equipment (Baghouses)
  • Drying & Cooling Equipment (Baghouses &
    Scrubbers)
              Boilers & Pulp Dryers
              Combustion Sources

   Boilers – Coal & Natural Gas Firing
    • Beet Processing (Steam) – 300,000 to 450,000 lbs/h
    • Juice Processing (Steam) - ~ 200,000 lbs/h


   Pulp Dryers – Coal & Natural Gas Firing
    • Dried Pulp Production - ~350 to 600 tons/d dried pulp
    • In 2006, a $17,000,000 steam pulp dryer was installed at
      the Nampa facility. Eliminated coal-fired drying.
     Emissions Estimation Methods

   Periodic stack tests (boilers & pulp dryers)

   EPA AP-42 – Compilation of Emission
    Factors

   Mass Balance

                 Conclusions
   TASCO facilities and other Idaho point
    sources account for a small fraction of
    overall emissions.

   Mobile and area sources account for the
    majority of the overall emissions.

   TASCO coal usage and emissions are
    insignificant relative to U.S. electric
    utilities.
         Conclusions (Continued)

   Based on total annual criteria pollutant
    emissions estimates…

    • County Level – TASCO facilities account for 6
      to 10% of overall emissions.

    • State Level – TASCO facilities account for
      ~ 1% of overall emissions.
