CHARLOTTE -- On Monday, City of Charlotte officials announced a new proposal to transfer coal ash near Mountain Island Lake to Charlotte-Douglas Airport.
The lake provides the drinking water to 800,000 people in the Charlotte area.
In May, airport leaders rejected an initial proposal by Duke Energy to transfer coal ash to the airport.
The original plan also called for a private company to store the ash as fill underneath a new runway or infrastructure.
City officials can't release many details but say it's a solid plan.
"Our counter proposal is, in short, good for the airport and consistent with the ethics and values and principles that the city has and that we've been operating under," said Hyong Yi, City of Charlotte.
Duke Energy is reviewing the counter proposal and is expected to have a response sometime next month.
The North Carolina General Assembly is also debating legislation that would require the removal of coal ash from sites across the state - including near Mountain Island Lake.
