한국에서 오염준설물질관리를 위한 위해도 정보에 근거한 의사결정 체계

Abstract

To meet pending London Protocol requirements, South Korea is preparing to reduce the need for disposal of dredged material at sea. The new requirements controlling ocean disposal of dredged material pose significant challenges to the South Korean government because the previous practice of offshore disposal of contaminated dredged material will no longer be possible after August 2008. Hence, other alternatives for treating and disposing of contaminated dredged material are being evaluated and selected for implementation. A new management and decision framework is therefore needed for regulators and implementers to show what information and what processes were used to make the decision and to increase administrative transparency for such projects in the public domain. To address this need, a framework was developed that offers an iterativeapproach to dredged material management that includes the essential elements of process, people, and tools needed for successful environmental decision making. The framework has six steps, incorporating problem definition, developing objectives and criteria, identifying alternatives, performing the evaluation, comparing alternatives and selecting the preferred alternative. The primary objective of the framework is to provide a systematic means of exploring dredged material management alternatives in South Korea usingcriteria that integrate risk, and economic and stakeholder value information. The framework incorporates the desired decision making attributes of transparency, comparative analysis, and inclusion of public input. While developed for South Korea, the framework can be applied in any situation where dredged material management alternatives are being considered to manage contaminated sediment risks.
