Wyodak''s calculations artificially moved the mouth of the mine significantly closer to the coal face, thereby reducing its direct mining costs and, accordingly, the taxable value of its coal. [¶12] In 2013, Wyodak filed amended returns for production years 2009, 2010 and 2011.
The highest coal production in the Region is from the Wyoming part of the Powder River Basin, from the WyodakAnderson coal zone. According to figures from the Energy Information Administration (EIA, 1998) the total coal production for 1997 from the Northern Rocky Mountains and Great Plains Region (all coal produced in
Reduction in the value of the exotherms between the first and second runs for the Wyodak coal suggests that some CO2 is irreversibly bound to the structure even after heating to 200 °C.
