  • Among large developmental projects, those of the government and public institutions with the total budget of more than 50billion wons can be executed only when the feasibility of the project has been testified through the procedure of preliminary feasibility study. Multi-purpose dams are public structures that can supply water, produce electricity, and control flood, they belong to large national projects that require legal evaluation procedures such as preliminary feasibility study and environmental impact assessment(EIA). The index that should be considered to be important in dam plan is the migration of residents in submerged district. The importance in the preliminary feasibility study is 4.93 points(98.6 in the scale of 100 at maximum). Among the 12 assessment elements of the policy and economy in the preliminary feasibility study, the element of environment assessment is turned out to be 4.68 points in the assessment importance (93.5 in the scale of 100 at maximum), which is the second in the total ranking and the first in the field of policy, indicating that the element is very important in dam construction planning.

  • The energy production of offshore wind farms plays an important role in expanding renewable energy. However, the development of offshore wind farms faces many challenges due to its incompatibility with marine environments and its social acceptability among the local community. In this study, we reviewed the marine environmental impact assessment status of offshore wind farm development projects for 2012-2019 in South Korea. A total of nine projects were selected for this study, all of which experienced considerable conflict with local fisheries resources. To appropriately respond to the underlying challenges faced by offshore wind farm development and in order to better support decision-making for future impact assessment, our findings identified: i) a need for adequate preliminary investigation and technical examination of fisheries resources; ii) a need to assess and estimate the impact of underwater noise, vibration, and electromagnetic waves on fisheries resources during wind farm construction and operation; and iii) a need for a bottom-up approach that allows for communication with local stakeholders and policy-makers to guarantee the local acceptability of the development.

  • Environmental Impact Assesment(EIA) is composed of various procedures, such as screening, scoping, inventory survey, prediction, assessment, mitigation measure, alternative assessment, and post management. Remote sensing introduced lately begins to be applied ecosystem and land use in inventory survey and assessment of EIA. This study explains on land use classification, buffering analysis of residential area, and overlaying analysis of odor predictive data with residential area for application to EIA with remote sensing data. Residential area extracted from land use classification of remote sensing provides effectively buffering analysis of residential area in selection of landfill site with GIS. It could assess also residential effect to an offensive odor by overlaying analysis. Application methods in EIA should be enlarged to assess effectively.

  • Preliminary ecological environmental assessments including physico-chemical constituents, water quality, fish fauna analysis, physical habitat health, and ecological health assessment were conducted as a primary step for Jeungchon micro-habitat ecosystem restoration in 2012. Water chemistry analysis of conductivity, dissolved oxygen, chlorophyll-a and etc. indicated that there were no significant differences(p < 0.05) among 6 sites between the headwaters and downstream. Multi-metric model analysis of Qualitative Habitat Evaluation Index(QHEI) showed that brooklets were at "good condition" as a mean QHEI of 158.7(n = 6) and the longitudinal differences of the model values between the sites were minor(QHEI range: 153 - 165). Total fish species and the number of individuals were 12 and 481, respectively, and dominant species were Zacco platypus(49.5%) and Zacco koreanus(36.8%). Tolerance guild analysis showed that the proportion of sensitive species($S_S$) had a negative linear function[$S_S=86.35-0.31(D_H)$; $R^2$ = 0.892, p < 0.01] with a distance from the headwaters, while the proportion of tolerant species($T_S$) had a positive linear function($R^2$ = 0.950, F = 90.28, p < 0.001) with the distance. Trophic feeding guild analysis showed that the proportion of insectivore species($I_n$) had a negative linear function($R^2$ = 0.934, p < 0.01) with a distance from the headwaters, while the proportion of omnivore species($O_m$) had a positive linear function($R^2$ = 0.958, p < 0.001) with the distance. Index of Biological Integrity(IBI) model, based on fish assemblages, showed a "fair condition" as a mean IBI of 23(n = 6), and there was a distinct differences of ecological health between the headwaters(S1 = 30; "good condition") and the downstreams(S6 = 14; "poor condition"). Overall, the preliminary environmental impact assessments suggest that water quality, physical habitat conditions(QHEI model), and ecological health(IBI model) were maintained well, even if the state was not an excellent conditions.

  • The Protocol on Environmental Protection to the Antarctic Treaty was ratified in 1991. With the aim to ensure comprehensive protection of the Antarctic environment, it contains provisions on environmental protection and conservation of the Antarctic area, including provisions for Environmental Impact Assessment. Environmental Impact Assessment is a method used to predict environmental impacts at an early stage in project planning and design, and find ways to mitigate or prevent adverse impacts in order to maintain balance between development activities and environmental conservation. Internationally, the Environmental Impact Assessment (EIA) in the Antarctic is classified into three types - preliminary, Initial, and Comprehensive - based on the environmental impacts of the proposed activities. In case of the Preliminary Environmental Review (PER), proposed activity may proceed in accordance to the national procedures and drafting of an outline. However, Initial (IEE) and Comprehensive Environmental Evaluation (CEE) assess and verify the impacts of the proposed activity, and require methods or alternatives for mitigating or eliminating negative impacts on the environment. Although Korea's Act of 'Activities and Environmental Protection in Antarctica' also includes provisions on EIA for activities in Antarctica, there are obvious contrasts with the EIAs currently being conducted in Korea, in regards to deciding the level of EIA through screening and identifying key issues for assessment through scoping. In order to implement the proper EIA, more improved methods for drafting and reviewing the EIA to Antarctica in Korea are necessary.

  • Since 2001, the Pangyo district multipurpose rural water development project has been promoted as a new target project for stable supply of agricultural water and improvement of the living environment of rural areas in Seocheon-gun. Detailed data analysis and logic must be reinforced, focusing on the items reorganized by the reorganization of the preliminary feasibility study. The purpose of this study is to promote the smooth promotion of projects by conducting a policy effect assessment following the reorganization of the preliminary feasibility study system. This study conducted a policy assessment of agricultural infrastructure improvement project for preliminary feasibility study. The policy assessment is divided into three parts: project implementation conditions, policy effects and special assessments. The newly established policy effect is to assess the job effects, living conditions impact, environmental evaluation, and safety evaluation that contribute to the quality of life. Sixteen policy assessment items were selected and evaluated quantitatively and qualitatively. The results of the study are expected to provide basic data for the comprehensive judgment of the preliminary feasibility study of agricultural infrastructure improvement project in the future.

  • 환경적 가치를 보존하고 개발로 인한 부정적 영향을 최소화하기 위하여 환경영향평가 제도가 수행되고 있다. 현재의 환경영향평가의 객관성 강화하기 위해 데이터 기반으로 전환이 필요한 시점이다. 또한 국가 차원의 다양한 공간정보 제공 및 환경영향평가에 공간정보 연계 가능성을 통해 환경영향평가제도의 공간정보 활용 확대가 요구되고 있다. 그러나 현재 환경영향평가에서 공간정보가 체계적으로 활용되고 있지 않는다. 또한 환경영향평가 업무 종사자(담당 공무원, 환경영향평가서 대행기관, 검토기관 등)들은 공간정보 개념에 대한 이해도가 부족하여 효율적으로 활용하는데 한계가 있다. 이러한 공간정보 활용의 한계점을 개선하기 위하여 본 연구에서는 공간정보 표준화(좌표, 속성 테이블) 방안을 제안하였다. 이를 위해, 국가 공인의 좌표계 및 표준을 기반으로 표준 좌표계를 제안하였으며, 환경매체별 조사 항목의 데이터 테이블의 기본항목을 9개로 설정하였다. 마지막으로, 전술된 표준화를 실제 환경영향평가 사업에 대하여 시범 적용하였다. 본 연구에서 제안한 표준화 방안은 환경영향평가에서의 공간정보 활용 활성화 및 평가 분야의 범위 확장에 기여할 것으로 사료된다.
