Matson Terminals will pay a civil fine of $725,000 for violating the federal Clean Water Act when molasses spilled into Honolulu Harbor in 2013.

The U.S. Environmental Protection Agency announced the settlement Thursday.

“Dockside facilities must ensure their operations do not pollute nearshore waters,” Alexis Strauss, EPA’s Acting Regional Administrator for the Pacific Southwest, said in a press release. “The Honolulu Harbor spill affected marine life, coral reefs and kept residents and visitors from enjoying the city’s incomparable coastal environment.”

Matson spilled 233,000 gallons of sugarcane molasses into the harbor during ship-loading activities.

The discharge killed 25,000 fish in the harbor and damaged coral reefs in the area.

Officials collected tens of thousands of dead fish after a molasses spill in Honolulu Harbor in 2013.

Matson no longer ships molasses from Honolulu Harbor.

In 2015 Matson paid a $400,000 fine plus restitution of $600,000 “after pleading guilty to criminal charges of unlawfully discharging molasses” into the harbor.

The restitution was divided between Waikiki Aquarium for coral reef programs and invasive algae cleanups, and Sustainable Coastlines Hawaii “to inspire local communities to care for coastlines through beach cleanups.”

Matson also reached an agreement with the state of to stop transporting molasses through Honolulu Harbor, to remove its molasses distribution system, to pay for re-growing corals that were damaged or destroyed, and to reimburse related cleanup costs, says the EPA.
