1.1.1 Incident Category
Emergency Response
1.1.2 Site Description
On November 14, a 470 gallon tank containing anhydrous ammonia washed up on a marine beach at the Tulalip Indian Reservation. Department of Ecology and the Coast Guard responded to the scene first, and EPA was requested to provide air monitoring support. The tank was found to be structurally deficient and still containing approximately 100 gallons of ammonia. AreaRAEs were set up in between the tank and nearby residences to monitor ammonia levels.
1.1.2.1 Location
The closest Residence to tank is located at 11402 Tulare Way W, Tulalip, WA 98271. Tank is located 500 feet SE of residence on the beach on the Tulalip Indian Reservation.
1.1.2.2 Description of Threat
Structurally deficient ammonia tank containing approximately 100 gallons of ammonia that is leaking slowly.
1.1.3 Preliminary Removal Assessment/Removal Site Inspection Results
The tank is in poor condition so it was deemed too dangerous to try to move for proper disposal. The tank will be vented in place with AreaRAE monitoring for ammonia concentrations.

2.1.1 Narrative
On November 13. 2011, at approximately 1300, Tulalip Fire Department responded to a incident of a tank that washed up on a beach on the Tulalip Indian Reservation that smelled of ammonia. Washington State Department of Ecology and the USCG were contacted and arrived on scene at 1600. At 1800, EPA assistance was requested, and OSC Dettling and 2 START contractors were mobilized. EPA START arrived on scene at approximately 2100. The tank was assessed along with members of NRC, an Ecology contractor, to determine whether or not the tank could be moved for disposal. Upon investigation of the tank, two bullet holes were discovered. This in conjunction with a heavily corroded valve led to the decision to stabilize and carefully monitor the tank. NRC moved the tank further up the beach and secured the tank at approximately 0100 on 11/14/11. EPA set up AreaRAEs to monitor ammonia in between the tank and residences 0.10 miles away.
2.1.2 Response Actions to Date
On 11/13/11 the tank was assessed at approximately 2230 to determine remedial options. In the early morning of 11/14/11 the tank was secured to the shoreline by NRC. EPA START continued to monitor Ammonia levels throughout the morning and afternoon. At 1500 on 11/14/11 NRC determined that the tank was mostly empty and plugged the holes in the tank. USCG relinquished control to Ecology at 1630. USCG, Ecology, EPA START, and NRC all demobilized from the site. NRC will return in the morning to remove the tank from the beach and remove any residual ammonia from the tank with a water as long as conditions allow the work to continue.
