Cooking Oil Recycling Facility Spill; Duwamish Waterway, WA

Duwamish Waterway, WA | 2021-Sep-21

Initial Notification: On the afternoon of Sept. 21, 2021, the NOAA SSC was notified of an approx. 900 gallon spill of cooking oil at the Mahoney Environmental Restaurant Cooking Oil Recycling Facility. The incident occurred after a truck collided with a used cooking oil storage tank at the facility. A majority of the oil spilled on concrete and was recovered. Approx. 200 gallons flowed into a bioswale near the Duwamish River, saturated the soil, and is creating a sheen on the Duwamish which is boomed. USCG SPS has hired a contractor to remove oil saturated soil from the bioswale.
