A coal-fired power plant on the Ohio River upstream of Maysville, Kentucky, has shut down temporarily following an explosion that injured six workers.
As noted in this article from the Maysville newspaper, there has been talk that Killen could be shut down permanently in the near future, and what will happen after the explosion remains to be seen.
EDIT: The explosion was at the J.M. Stuart generating station. Both Stuart and Killen are upstream of Maysville, and both have been listed as candidates for closing.
