In this study, the authors investigated the change of marine environment by dumping dredged materials generated by construction of Busan New Port. There are lots of possibilities to impact an ocean ecosystem by toxic materials in the dredged material dumped in the open seas. As a result of analysis of environmental monitoring in the study areas 12 times a year, COD is II grade, T-N is I grade, T-P is between II and III grade. This result is same as another results of offshore in Korea. It seems unclear that it results from the change of water quality by dumping dredged material. However, according to the result of this investigation, it is not effected extensively to the marine environment by dumping dredged materials. We need further environmental monitoring in the interest sea areas, also need to keep on investigating the impact on the marine ecosystem by dumping dredged materials.

A wide range of projects for ocean renewable energy are currently in development around the world and ocean energy industries continue to receive significant support from their governments. Surrounded by sea on three sides, Korea has potentially abundant renewable ocean energy resources, which include tidal current, tidal range, offshore wind power, osmotic pressure and ocean thermal energy. Numerous ocean renewable energy projects has been developed in Korea. Nevertheless, there are some concerns that those developments often select an environmentally unsuitable location and/or there are very few existing information on those environmental effects. The purpose of this study is to improve supporting policies and regulation systems of ocean renewable energy development in Korea by reviewing and compiling government policies and environmental assessment systems related to ocean renewable energy development around the world. The study suggests several policy implications for its environmental-friendly development in Korea, including requirements of strategic environmental assessment for proactive and environmentally suitable site selection of ocean renewable energy development and continuous post-development environmental monitoring, and so on.

Environmental impact assessment(EIA) on the construction and operation of thermal power plant(TPP) is aimed at promoting sustainable coastal development by clearly identifying the marine physics and organisms effects of the project on the surrounding marine environment and minimizing its impact. The primary purpose of this study is to establish EIA guidelines for TPP in order to assess how TPP construction projects influence marine environment and to establish the mitigaion plans of environmental impacts. Through this study, scientific and efficient EIA guidelines for the marine environments were established by a specialist forum consisted of officials from the Ministry of Environment and the Ministry of Trade, Industry and Energy, personnel from five public corporations in charge of TPPs and marine environment experts. In the study, fifteen EIA reports (2009~2015) on TPPs submitted were analyzed to identify the shortcomings of current assessment items on marine environment and to collect a wide range of information including EIA report formulation regulations, domestic and overseas environmental survey guidelines and EIA review comments on TPPs. Based on the findings, a specialist forum put together EIA guidelines for TPP construction projects.

The Marine Environment QA/QC management system has been operated since 2010 to secure the reliability of data and improve the analysis capabilities of measurement and analysis institutions. From 2010 to 2020, the cumulative number of measurement and analysis institutions participated in the QA/QC management system was 266. And the number of certificates issued by the ministry of oceans and fisheries is 182. A total of 32 reference materials for proficiency testing and interlaboratory comparisons have been developed. They were first developed focusing on items (Nutrients, COD) commonly analyzed in marine environmental measuring network, marine pollution impact surveys, sea area utilization impact assessment, deepsea water surveys, and information network on fishing ground environments. In addition, it is time to expand the filed of the QA/QC management system, such as seawater temperature, salinity, PCBs and PAHs in sediments, which are mainly analyzed in most monitoring programs. On-site assessment has been conducted for 162 laboratories according to ISO/IEC 17025 to evaluate their conformity of the quality management system and deficiency. In terms of management and technology requirements, about 4.2% of organizations showed insufficient division of duties among employees 8.7% of them revealed the lack of employee training. By test item, about 6.3% of organizations showed the lack of standard substance management and the state of the cleaning glassware was pointed out in about 5.4% of them. The QA/QC management system should be continuously supplemented by identifying the causes of nonconformities and area for improvement.

In order to understand the effects of the main components of antifoaming agents on the marine benthic ecosystem when silicone-based antifoaming agents are discharged into marine environments, eco-toxicity testing was performed on silicone and alcohol-based antifoaming agent by using benthic amphipod (Monocorophium acherusicum) and luminescent bacteria (Vibrio fischeri). The toxic effects of Polydimethylsiloxane (PDMS) as a main component of silicone-based antifoaming agents on aquatic organisms were also researched. In the results of the eco-toxicity test, luminescent bacteria showed a maximum of 9 times more toxic effects than benthic amphipod for alcohol-based antifoaming agents, and silicone-based antifoaming agents showed a maximum of 400 times more toxic effects than alcohol-based. The $LC_{50}$ and $EC_{50}$ values of PDMS ranged from 10 to $44,500{\mu}g/L$ in phytoplankton, invertebrate, and fish. In the results of applying PBT (P: persistency, B: bioaccumulation, T: toxicity) characteristics as an index showing the qualitative characteristics of PDMS, persistency (P) and bioaccumulation (B) were confirmed. Thus, when PDMS is discharged to marine environments, it could accumulate in the upper trophic level through bioaccumulation and the food chain, which could have negative effects on benthic organisms. The results of this study may be used for objective and scientific risk assessment, considering the major components of antifoaming agents when investigating the effects of various discharged antifoaming agents in marine ecosystem.

This study examines the policy direction for energy self-reliant islands using marine energy. In other words, it was suggested that the environmental characteristics of the ocean should be considered by conducting a strategic marine environmental impact assessment when establishing an energy-independent island project plan. It was also suggested to proceed with preemptive site selection. In particular, it was emphasized that continuous monitoring of the marine environment should be carried out during the construction and operation of the marine energy development project. In addition, I emphasized the need to seek ways to expand marine environmental impact data and to actively participate and support the residents of the island, which is important in promoting self-reliant islands using ocean energy. This can be said to have a high probability of success when the government-led smart grid project group and KEPCO collaborate with each other. The results of the study analyzed through literature review are as follows. First, active participation and support for initiatives led by residents are needed. second,. KEPCO must collaborate with specialized public institutions such as the Smart Grid Project Group. Third, a strategic marine environment impact assessment should be introduced. Fourth, continuous marine environmental impact investigations should be conducted.
