HISTORICAL DISPERSANT AND IN-SITU BURNING OPPORTUNITIES IN THE UNITED STATES
ABSTRACT Evaluating the value of using dispersants or in-situ burning in various regions of the United States requires an estimate of how often such technology might reasonably be considered. This study collected information on marine oil spills of 1000 barrels or more occurring in the coastal and offshore waters of the United States (excluding Alaska) from 1973 through June 1994. Each incident was examined using criteria for oil type, weather conditions, water depth, and distance from the shoreline. This allowed the frequency and geographic distribution of dispersible and burnable spills to be estimated. The effect of modifying the criteria on the frequency distribution of dispersible and burnable spills was evaluated. Data were obtained on 138 refined product and 69 crude oil spills. The majority of these spills occurred in shallow water, close to the shoreline, and/or close to a sensitive receptor. Depending on the severity of the criteria, between 10% and 51% of the crude oil spills and 4% and 18% of the refined oil spills studied were realistic candidates for dispersant use. Between 35% and 58% of the crude and 22% and 38% of the refined oil spills were realistic candidates for burning.
