A team of 40 volunteers on four boats, led by the nonprofit Ocean Defenders Alliance (ODA), successfully removed 32 tires from a "tire graveyard" in Kailua Bay on April 6, 2025.
This was the final phase of a two-part cleanup, with 61 tires having been removed in the first phase on April 22, 2024.
The tire dump, located 600 yards offshore from the Royal Kona Resort, was discovered by local diver Jeff Milisen. His wife, Sarah Milisen, who leads the local ODA chapter, organized the cleanup effort. The tires, each weighing around 190 pounds, were floated to the surface with lift bags and craned out of the water.
The project highlights a significant community effort to protect the local marine ecosystem from the damage and chemical leaching caused by the tires.
The tires, averaging about 190 pounds, were floated to the surface with lift bags and then hauled out of the water by a crane attached to the vessel of Blue Ocean Mariculture
