Chesterfield Unit 6 Scrubber

• Began operating in Spring 2008
• Removes 95 percent of SO2, 90 percent of
  mercury
• Part of 650 million station investment in air
  emission control equipment in 2008
• Construction underway for another scrubber to
  handle Units 3, 4 and 5, expected to be
  operational in 2011

Long-term Solutions Virginia City Hybrid Energy
Center

• Wise County project meets baseload energy needs
  and has strong environmental features.
• Will produce 585 MW of power using DOE-designated
  clean coal technology.
• Complete environmental package
• Protects air quality
• Uses waste coal and biomass
• Minimizes water use
• Designed for carbon capture and
• storage technology to be added later
• What Dominion has proposed is the full up
  suite of controls. It is the best there is.

Virginia City Hybrid Energy Center

• Circulating Fluidized Bed Characteristics
• High fuel flexibility- only technology that can
  use wide range of fuels available in Southwest
  Virginia
• 3,000-13,500 BTU/ fuel
• 5-50 Ash (Potentially higher)
• 1-4 Sulfur (VCHEC Sulfur content restricted by
  Air Permit)
• Demonstrated, proven reliability - Availability
  is 90-95
• Can meet strict emission regulations

VCHEC EmissionsCompared to Other Facilities

• SO2 emissions are uncontrolled (60s), 90 (70s),
  95 (80s), 99.8 (90s) with 1.5 and 2 sulfur
  coal
• NOX emissions from AP-42, MS Uncontrolled, CFB
  w/o SNCR, w/ SNCR,
• PM emissions are uncontrolled, 99
  control,99.5,and 99.6
• Hg uncontrolled based on .15 ppm,81, typical
  values and 99 for VCHEC

Virginia City Hybrid Energy Center

• Station Operations
• 1,700 acre site
• Receipts 6 days/week, between 7 AM and 5 PM
• Will have requirements for
• Coal/Coal Waste
• Woody Biomass
• Limestone
• Other (PAC, Lime, Ammonia, No. 2 oil)
• Auger Sampler used for quality control
• Two coal truck unloading sites (four hoppers)
• One limestone unloading site - (two hoppers)
• Two biomass unloading sites

15
VCHEC Material Handling

• Traffic Study showed no issues with flow on US
  58, at worst case hourly traffic assumptions.
• Alternate 58 Stoplight showed volume to capacity
  ratio of 1 at twice the required hourly worst
  case traffic

16

• The permit requires each coal product shipment be
  sampled.
• VCHEC will check shipments via on-site auger
  sampler

The station will blend two grades of coal product
(Low Grade 3000 to 8000 Btu/lb, and High Grade
8000 to 13000 Btu/lb) to achieve a target blend
rate of 7700 Btu/lb to the boiler.

• INPUT LIMITS
• Maximum sulfur average 1.50 (calculated on a
  rolling 12 months)
• Maximum Btu per boiler 27.4 trillion Btu
  (rolling 12 month)
• Approximate total coal volume (at target Btu)
  3.52 million tons
