This final report summarizes the work accomplished under the program entitled Study to Define Arctic Pollution Response Systems and Develop Arctic Oil Pollution Response Project Plans. The objective of the program was to determine the most cost effective, environmentally compatible, and technically feasible Coast Guard arctic pollution response system that can be used in projected oil spill scenarios to recover and dispose of spilled oil. The optimum arctic pollution response system was determined by establishing the cost and effectiveness of response for sixteen oil spill response situations, and developing six alternative Coast Guard arctic pollution response systems based on these situations. These six systems were developed with a recognition of three distinctly different types of operational requirements, those for thick stable ice, dynamic hummocky ice, and open water or light ice conditions. The optimum system was then identified as the result of a cost effectiveness analysis. The six arctic oil spill scenarios consisted of a gathering pipeline rupture in the nearshore Beaufort Sea, an oil well blowout from a very large reservoir in the nearshore Chukchi Sea, crude oil tanker casualties in Norton Sound and in the Navarin Basin region of the Bering Sea, an oil well blowout from an average sized reservoir in Bristol Bay, and a fuel oil spill resulting from the collision of a fuel oil barge in Unimak Pass. The optimum system provides for a 25 response level for the Norton Sound, Navarin Basin, Bristol Bay, and Unimak Pass scenarios, and a 50 response level for the Beaufort Sea and Chukchi Sea scenarios.
