1Beginning in 2001, includes a small amount of refuse recovery (coal recaptured from a refuse mine,
and cleaned to reduce the concentration of noncombustible materials).		 5Electric power sector factors are for anthracite, bituminous coal, subbituminous coal, lignite, waste
coal, and, beginning in 1998, coal synfuel.
2Waste coal (including fine coal, coal obtained from a refuse bank or slurry dam, anthracite culm,
bituminous gob, and lignite waste) consumed by the electric power and industrial sectors.  Beginning in
1989, waste coal supplied is counted as a supply-side item to balance the same amount of waste coal
included in "Consumption."		 R=Revised.  P=Preliminary.  NA=Not available.  
3Includes transportation.  Excludes coal synfuel plants. Note:  The values in this table are for gross heat contents.  See "Heat Content" in Glossary. 
4Electricity-only and combined-heat-and-power (CHP) plants within the NAICS 22 category whose
primary business is to sell electricity, or electricity and heat, to the public.  Through 1988, data are for
electric utilities only; beginning in 1989, data are for electric utilities and independent power producers.		 Sources:  See "Thermal Conversion Factor Source Documentation," which follows Table A6.
