"CHARLOTTE, N.C. — Duke Energy is asking a judge to prevent citizens groups from taking part in any enforcement action that would make the company clean up nearly three dozen coal ash pits across North Carolina.
The Department of Environment and Natural Resources filed a complaint against Duke last year. Several citizens groups got involved in the case, saying the waste dumps polluted groundwater.
But Duke filed a motion Monday to remove the citizens' groups from the case.
The company said the groups have an "independent right" to file claims and seek relief. But they are "prohibited from expanding this enforcement action beyond the claims asserted and relief sought by" the state environmental agency."
