MANILA - Philippine Senator Imee Marcos has demanded an explanation from the government and military for the shipment of millions of gallons of fuel by the US Navy to Subic Bay in the Southeast Asian country.

In a statement published Wednesday evening, citing data from several international shipping trackers, Marcos said the oil cargo was loaded at Pearl Harbor in Hawaii on the US-registered tanker Yosemite Trader on Dec 20 and remained some 50 km west of Subic Bay as of Wednesday morning.

Marcos, who chairs the Senate Committee on Foreign Relations, criticized the "inexplicable silence" of both the Philippine and US governments before the shipment, accusing the government and the US of depriving the Filipino people of the right to know

The United States Embassy in the Philippines on Thursday confirmed that the US military transferred fuel to Subic Bay from the US military storage facility at Red Hill, Pearl Harbor, Hawaii.

Marcos, who chairs the Senate Committee on Foreign Relations, criticized the "inexplicable silence" of both the Philippine and US governments before the shipment, accusing the government and the US of depriving the Filipino people of the right to know.

"(Storing massive fuel) is not just an issue of foreign policy but of Philippine sovereignty, even environmental safety. The government better have a clear explanation for this," Marcos said.

The Red Hill Bulk Fuel Storage Facility in Hawaii, a giant military fuel storage facility, was operated by the US Navy and designed to support US military operations in the Pacific.

The US Navy has admitted that the World War II-era storage facility experienced two leaks in 2021, one in May and one in November, that spilled more than 30,000 gallons of fuel, contaminating drinking water on the island of Oahu, reportedly sickening thousands of people.

In November 2022, an estimated 1,300 gallons of aqueous film forming foam, which is used in firefighting and slow to degrade in the environment, spilled in the facility, triggering an ongoing water contamination crisis jeopardizing nearby communities.

The Red Hill facility is in the process of being defueled and closed. The US Navy is hoping to finish defueling by 2024 and permanently close the facility by 2027.

Some Philippine activist groups for peace also questioned the military fuel transfer, labeling it as "war fuel".
