Mirant Wyandotte, LLC

  1. Name of the facility:
      Mirant Wyandotte, LLC

  2. Location:
      Wyandotte, Wayne County, Michigan, 48192

  3. Distance from the US/Canada border:
      less than 50 km

  4. Type/size of the facility:
      proposed installation of a 644 MW natural gas-fired turbine electrical generating facility, consisting of two combustion turbines, two fuel preheaters, two start-up boilers, an emergency fire pump engine, and a cooling tower.

  5. Source of emissions:
      the turbines, start-up boilers, preheaters, emergency fire pump engine, and the cooling tower.

  6. Type of fuel:
      except for the emergency fire pump engine, which uses diesel fuel, all combustion equipments will use natural gas.

  7. Type/quantity of emissions:
      Pollutant       Allowable Emissions (tpy)
      PM10       149.7
      SO2       53.4
      NO2       331.8
      CO       524.4
      VOC       163.3
      HCOH       9.9
      H2SO4      12.3
      NH3       155.5

  8. Emission control technology:
    • dry low NOx burners and selective catalytic reduction (SCR) for NOx reduction,
    • good combustion techniques and catalytic oxidation add-on control for reducing CO, VOCs, and toxic air contaminants,
    • efficient combustion practice to control PM10,
    • use of pipeline quality natural gas for PM10 and SO2 control,
    • proper operational practice for SCR system to control ammonia.

  9. Date permit application received:
      MDEQ received the permit application on January 3, 2002, and USEPA received the draft permit on October 16, 2002.

  10. Stack height and diameter:
      each turbine has a stack of 145 ft height and 216 in diameter
