Protect Oʻahu’s Drinking Water

Take action to protect Oʻahu’s water – sign our petition TODAY!
Kapūkaki, known today as Red Hill,
is a mountain ridge located between the ahupuaʻa of Hālawa and Moanalua in the ʻewa district of Oʻahu.
For more than 70 years the United States Navy has stored fuel inside this ridge a mere 100 feet about Oʻahu’s primary drinking water supply. In that time, the facility has leaked more than 30 times with the last known leak occurring in January 2014, when 27,000 gallons of fuel was released from a single tank. This leak resulted in a 20-year agreement between the U.S. Navy, Environmental Protection Agency, Defense Logistics Agency, and the Hawaiʻi Department of Health to study, monitor and consider improvements to the storage facility.
The U.S. Navy’s Red Hill Bulk Fuel Storage Facility
holds twenty fuel storage tanks, 18 of which are active. Total, these tanks store 225 million gallons of jet fuel or marine diesel—each tank big enough to fit Aloha Tower inside.
100 feet below this facility sits Oʻahu’s primary drinking water source, the Southern Oʻahu Basal Aquifer which serves over 400,000 residents and visitors. The Environmental Protection Agency determined in 1987 that this aquifer is the “principal source of drinking water” for the island, and that “if contaminated, would create a significant hazard to public health.”
At least 200,000 gallons of fuel have leaked into the surrounding environment from Red Hill.
This includes the 27,000 gallons that last leaked in 2014. While the drinking water is currently safe to consume, U.S. Navy studies are detecting traces of petroleum chemicals in the groundwater near the tanks.
The U.S. Navy, Environmental Protection Agency, and Hawaiʻi Department of Health have released no plan for cleaning up the leaked fuel and cannot guarantee these tanks will not leak again. It is clear that these tanks are outdated and it has been discovered that these tanks are out of compliance with today’s state and federal regulations on underground storage tanks.

In February 2018, the Sierra Club won their suit against the Hawaiʻi Department of Health—the court ruled that the exemption of the U.S. Navy’s Red Hill Fuel Tanks is a violation of state law. Read more here.
Hawaiʻi’s Department of Health is responsible for regulating underground storage tanks and protecting our drinking water. State law specifically directs the Health Department to enact rules that require existing underground storage tanks be upgraded to prevent releases of petroleum into the environment. Their current regulations, however, do not ensure underground storage tanks are properly upgraded.
This suit comes after the Health Department continued to overlook the sense of urgency in mandating repairs to aging underground storage tanks. The Sierra Club previously delivered official notice to the Health Department that their regulations on underground storage tanks fail to comply with a 1992 state statute in May. The 1992 law states, “Existing underground storage tanks or existing tank systems shall be replaced or upgraded not later than December 22, 1998 to prevent releases for their operating life.” This requirement applies to all tanks storing hazardous material underground, including the U.S. Navy’s Red Hill Bulk Fuel Storage Facility.

Tank condition: Worse than anticipated
In 2018, the Navy conducted testing, mandated by the AOC, to verify their assumptions about how these unique fuel tanks have aged over the last 75 years. The preliminary findings are astonishing. The Navy predicted that there would be minimal corrosion and that the steel liner would have thinned from the original 0.25-inches to between 0.187-inches and 0.135-inches. However, of the ten samples taken from tank 14, 5 samples revealed extensive corrosion at the top and along the sides of the tank. Several samples indicate thinning more severe than predicted. One sample from the side of the tank was only 0.079-of-an-inch thick—less than a third of the width of the original quarter-inch steel lining.
Proposed tank upgrades
Over the last couple of years, the Navy has studied six tank upgrade alternatives, ultimately choosing one to propose to the Environmental Protection Agency and Hawai‘i Department of Health. The Navy’s preferred choice is to maintain the current tank system, leaving what exists of the original 0.25- inch liner and recoat only the bottom of the tanks with epoxy. In their own report the Navy states “this alternative is nearly identical to the efforts conducted to inspect and repair the Red Hill tanks over the last 13 years.” In other words, the Navy is choosing the least expensive, least protective option—to maintain status quo.
No choice but to shut it down
The tanks at Red Hill were not meant to last forever. With thinning steel walls and no plan to update tank structure to ensure protection of our water, we are calling on the Navy to shut down the Red Hill facility and relocate the fuel away from the drinking water supply.
