On November 13, 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.
