An internal review by the U.S. Coast Guard found that its response to the colossal Deep Water Horizon oil spill in the Gulf of Mexico last year was hindered by its lack of preparation and reduced response capabilities; the 158 page review said that the government and private sector “demonstrated a serious deficiency in planning and preparedness for an uncontrolled release of oil from an offshore drilling operation”; in response to the review, R. J. Rapp Jr., the commandant of the Coast guard, said that his agency would pay greater attention to industry oil-spill response plans, begin preparing for future accidents, and conduct a study on the large use of chemical dispersants on the environment
