Notes: Other States include Alaska,
Arkansas, California, Iowa, Kansas, Louisiana, Maryland, Mississippi, Missouri,
Oklahoma, Tennessee, and Washington. "Recoverable Reserves at Producing
Mines" includes no reserves at mines that produced less than 10,000 tons
in the calendar year. These small mines are not required to provide
reserves data. Excludes silt, culm, refuse bank, slurry dam, and dredge
operations except for Pennsylvania anthracite. Totals may not equal
sum of components due to independent rounding. .
* = Data round to zero. W = Withheld to avoid disclosure of individual company data.
