"An environmental group says Duke Energy is polluting a lake and two river basins with coal ash from its Person County power plant, and gave formal notice Monday that it will sue over the alleged violations.

The utility company disputes those accusations and says the waters are safe.

The Southern Environmental Law Center filed the required 60-day notice under the federal Clean Water Act on behalf of the Roanoke River Basin Association. The litigation organization contends that Lake Hyco and the Dan River and Roanoke River basins near the Roxboro site have been illegally polluted."
