A recent court decision is casting new light on what to do about Red Hill. It's where the military has 20 massive underground steel tanks; one, which leaked 27,000 gallons. A circuit court judge ruled that the state Department of Health improperly gave the military an exemption from underground fuel storage rules. The Sierra Club hopes the ruling will now give state health officials more reason to press for an expedited schedule to upgrade the facility.

The Conversation's Catherine Cruz talked with Sierra Club Hawaii's Executive Director Mart Townsend about the court ruling and potential actions.
