Environmentalists say, Plans to expand a coal ash pond in northern Kentucky should be reconsidered.

The pond in Trimble County being proposed by LG&E would have 100 foot tall walls and a larger capacity than an ash pond in Tennessee that failed last year and released 5.4 million cubic yards of waste over hundreds of acres.

The new pond would sit on the floodplain of the Ohio River about 30 miles upstream from Louisville's drinking water intake.

Company officials say the pond would be safe but environmentalists say the state should wait until December when the Environmental Protection Agency issues new rules for handling coal ash.
