The Martin County coal slurry spill was a mining accident that occurred after midnight on October 11, 2000, when the bottom of a coal slurry impoundment owned by Massey Energy in Martin County, Kentucky, broke into an abandoned underground mine below.[1] The slurry came out of the mine openings, sending an estimated 306 million US gallons (1.16 million cubic metres; 1.16 billion litres) of slurry down two tributaries of the Tug Fork River. By morning, Wolf Creek was oozing with the black waste; on Coldwater Fork, a 10-foot-wide (3.0 m) stream became a 100-yard (91 m) expanse of thick slurry.
