CHARLOTTE, MECKLENBURG COUNTY -

Charlotte officials and Duke Energy are still considering Charlotte Douglas International Airport as a site for millions of tons of coal ash now at Mountain Island Lake.

The Charlotte Observer reported that a city committee said Monday that Duke is considering the city's counterproposal to the company's original idea of putting ash under the runways.

It's unclear where the ash might go.

An assistant city manager said he hopes to have a recommendation next month. He said the city has not asked Duke what alternative it is considering besides the airport plan.

City officials have looked at sites for the ash north and south of the airport's westernmost runway. Charlotte Douglas owns the land, but it is not used as part of the airfield.
