**Kentucky coal resource values are considered by some to be too high, while the Eastern Kentucky "Demonstrated Coal Reserve Base" value is still openly rejected by many as being too low.

Eastern Kentucky Low-Sulfur Coal

The U.S. DOE estimates that over 32.3% of Eastern Kentucky’s Demonstrated Reserve Base (DRB) would meet a 0.6 pounds of sulfur dioxide per million Btu emissions limit (low sulfur), and that 45.9% would meet a 1.67 lb/mm Btu emissions limit (medium sulfur).

Summary Sulfur Content Categories*


Sulfur Dioxide Emission Category (lb SO2 / mmBtu)

Converting "Percent Sulfur"
to "lb SO2 per million Btu"
lb SO2 / mmBtu =
%S X 19,500
Btu/lb of coal 

Examples for 12,500 Btu coal:

% Sulfur
1.0%
0.9%
0.8%
0.7%

lb/mm Btu
1.56
1.40
1.25
1.09
NOTE: Change % sulfur to Sulfur Dioxide Emission Category (lb SO2 / mmBtu) comparisons.
*EIA uses 6 sulfur content ranges. For general discussion and summary data, however, those 6 ranges are combined into 3 qualitative ratings of low, medium, and high-sulfur content.
