Initial Notification: USCG Sector Guam contacted the NOAA SSC the night of August 20 (U.S Mainland, August 21 in Guam) to request recommendation of a safe buffer distance for a methyl bromide fumigation operation scheduled to begin in Apra Harbor within a few hours. A Korean cargo shipment of gravel will be fumigated with methyl bromide due to detection of Salmonella by Guam EPA. A total of 750 pounds of liquid methyl bromide will be applied from 15 50-lb cylinders into 5 cargo holds (one measuring 5 meters depth x 20m x 20m, and 4 measuring 5m depth x 20m x 8m, with an application target of 3 lbs/1000 cubic feet). The fumigation will require 36 hours holding time followed by 4 hours to vent.
