HONOLULU (AP) - The U.S. Navy is pushing for the least expensive option in upgrading 20 massive underground fuel tanks that pose risks to a major source of drinking water on Oahu.

The Honolulu Star-Advertiser reports the Navy has assessed six options to improve the aging tanks at the Red Hill Underground Fuel Storage Facility, telling regulators last month that it would be recommending the option with "minimal changes to the status quo."

The option includes applying a protective coat that could cost up to $25 million per tank and upgrading its leak detection system.

In a deal with the Environmental Protection Agency and the state Department of Health, the Navy agreed to examine options to improve tank safety after 27,000 gallons (10,200 liters) of fuel leaked at the facility in 2014.
