* In October 2008, attorneys for the [[Dakota Resource Council]] wrote a letter to the federal Office of Surface Mining, seeking to block construction of a proposed coal drying plant in southwestern North Dakota. The Public Service Commission had previously decided a mining permit was not necessary, which the DRC contends is a violation of state and federal regulations. [[GTL Energy]] is developing the plant to remove the water content of lignite coal in order to increase its energy value.<ref>[http://www.localnews8.com/global/story.asp?s=9123861 "Enviro group seeks federal help in coal project,"] Associated Press, October 4, 2008.</ref>
* In August 2010 a study released by the [[Environmental Integrity Project]], the [[Sierra Club]] and [[Earthjustice]] reported that North Dakota, along with 34 states, had significant groundwater contamination from coal ash. The report, in an attempt to pressure the Environmental Protection Agency to monitor coal ash, noted that most states do not monitor drinking water contamination levels near waste disposal sites.<ref>[http://www.miamiherald.com/2010/08/26/1793995/study-of-coal-ash-sites-finds.html "Study of coal ash sites finds extensive water contamination"] Renee Schoff, ''Miami Herald'', August 26, 2010.</ref> The report mentions mentioned North Dakota's [[Antelope Valley Station]] and [[Leland Olds Station]] as sites that have groundwater contamination due to coal ash waste.<ref>[http://www.businessweek.com/ap/financialnews/D9HRDN581.htm "Enviro groups: ND, SD coal ash polluting water"] Associated Press, August 24, 2010.</ref>
