Dear Mr. Rankin:
Enclosed for your record are Tables 1-4 summarizing the potential radiological impact from the normal operation of Combustion Engineering's (CE) Hematite Plant. These tables were presented at the November 30, 1978 public hearing concerning the change in CE's NPDES discharge permit.
If there are any questions please feel free to call.
Sincerely, f
W. T. Crow, Section Leader Uranium Fuel Fabrication Section Fuel Processing & Fabrication Branch Division of Fuel Cycle and Material Safety
