Progress Energy Carolinas, Inc. has been informed by its coal suppliers that some coal shipments during the
winter months (December through March) will contain anti -icing fluids to treat the coal that is delivered to
several of its generating plants. The coal will be treated at the mine prior to shipping to the plants. The
coal is treated with chemicals to prevent the coal from freezing within the rail cars while in transit. These
chemicals will be applied at a rate of 2 — 4 pints per ton of coal, depending upon expected weather
conditions during transport.
The Sutton Steam Electric Plant will receive coal shipments during these winter months. Some of these
shipments may be treated with anti -icing fluids. Approximately 2,625 gallons of anti -icing fluid could be
added to each treated coal shipment. The potential chemicals added to the coal prior to shipment for anti -
icing are Benetech BT -910, Benetech BT -930, Freedom Industries FCA -2000, O'Brien Freezetrol 70, and
GEOMELT 55. There is a small potential that some of these chemicals can be discharged into the cooling
pond via storm water runoff from the coal pile. The cooling pond discharges into the Cape Fear River from
Outfall 001. This outfall is identified in Section A.(1) of our National Pollutant Discharge Elimination
System (NPDES) Permit No. NC0001422. There is a monthly aquatic toxicity monitoring requirement for
this discharge.
If you have any questions or comments regarding this information, please contact either Steve Cahoon,
Environmental Specialist at our HEEC at (919) 362 -3568; or Kent Tyndall, Environmental Specialist at
Sutton Plant at (910) 343 -3244.
