Hawaii | 2025-Aug-26

Initial Notification: U.S. Coast Guard (USCG) Sector Honolulu notified the Scientific Support Coordinator (SSC) that a Grotto Tour boat sank at the pier in the Wailua River in Kauai. An estimated 10 gallons of diesel were on board and a sheen was observed in the small harbor. The boat owner, with assistance from a team from the USCG small boat station and Hawaii Department of Land and Natural Resources, responded with sorbents and containment boom to prevent the release from moving out into the river. USCG requested the SSC assist with trustee notifications.
