Use of Dispersants in the United States: Perception or Reality?
ABSTRACT Dispersants have been a controversial oil spill response technique since their introduction during the Torrey Canyon oil spill off the coast of the United Kingdom in 1967. Despite reductions in the toxicity of dispersants and improvements in their application since then, dispersants have not been used extensively in the United States because of logistical difficulties, unfavorable weather conditions, and a lack of demonstrated effectiveness during actual spill conditions. In addition, there is a widely held perception in the United States that dispersant use has been limited by complex authorization procedures. This paper reviews the dispersant policies of several European nations and Canada and compares them with those of the United States. Recent developments in U. S. dispersant policy are outlined, particularly those designed to expedite decision making. The paper concludes by examining some recent U. S. oil spills in which dispersant use was considered.
