CHATTANOOGA. (AP) -- An Environmental Protection Agency official says storing coal ash without a liner at the site of the huge ash spill west of Knoxville should never make any groundwater in the area undrinkable.

EPA's project manager at the Tennessee Valley Authority's spill cleanup, Craig Zeller, told The Associated Press that if permanent test readings ever exceed "maximum contaminant levels" for drinking water, corrective action will be taken.

TVA's decision to keep more than 2 million cubic yards of coal ash at the site of its December 2008 spill in Roane County is causing concern for some people.

The onsite ash storage follows a year of shipping dredged ash to an Alabama landfill.

Environmental attorney David Ludder says his clients in Alabama "will be thrilled" by the change.
