우리나라는 약 30년 간 환경영향평가가 시행되고 있으며 이 기간 동안 환경영향평가의 대상 사업 및 평가 항목 등에 대한 다양한 개정이 수행되었다. 하지만 현행 환경영향평가법 상의 토양 관련 평가 항목은 토양 환경의 일부분에 국한하여 고려되고 있다. 본 연구는 국내 환경영향평가 지침을 분석하여 토양 관련 평가 항목을 분석하였으며 해외의 환경영향평가제도 내 토양 관련 평가항목을 분석하였다. 이를 통해 국내 환경영향평가 제도에서 토양 환경 평가의 문제점과 시사점을 도출하였다. 우리나라의 경우 환경영향평가 제도 내의 수질, 토양, 지형 지질, 수리 수문 평가 항목에서 토양과 관련된 인자를 분석하고 있다. 그 대상은 토양 오염도, 비옥토, 우수유출량, 비점오염원 등 주로 오염과 관련한 인자이다. 하지만 해외의 경우 토양 압밀, 토양 밀폐, 토양 염류화 등 토양의 기능 및 질과 연관된 항목을 분석 중에 있다. 우리나라 국토의 지속가능한 개발을 위하여 해외의 경우와 마찬가지로 토양 관련 평가 인자를 개정할 필요가 있다.

This study diagnosed the status of marine environmental impact assessment(MEIA) for project near the habitat of marine protected seagrass species such as Zostera caespitosa, Zostera asiatica, Phyllospadix iwatensis. For the preparation of a marine environmental impact statement, different monitoring parameters are used without any specific guideline for the assessment of current status. And also, both tools and techniques for MEIA are needed to improve for implementing. The monitoring plans and parameters are not considered well with the accuracy of the environmental predictions and effectiveness of any applicable mitigation measures. This study suggested the reasonable standard of the MEIA for the conservation of the marine protected seagrass species which have the habitat located near affected area. The inshore seagrasses need to be monitored including shoot count based on the "No Net Loss of Seagrass" as part of the monitoring parameters to assess the status of marine environment of environmental impact statement. In a process of effect prediction, we suggested a concentration of 10 mg/L suspended solids which added by the new developmental project near seagrasses habitat, referring to study of overseas case. But a further study for an appropriate standard is necessary effectively. In a mitigating process, priority needs to be considered in order of avoidance, minimization, reduction, compensation. In a post-monitoring process, it is necessary to monitor the seagrass species abundance to identify the variation of b/a (before and after) project. And in a case of implementing transplantation, survival rate need to be included to determine a success of project.

Environmental Impact Assessment (EIA) and Environmental Management Systems (EMS) are perceived by many to be separate environmental tools. EIA serves as a systematic and predictive tool for assessing the potentially significant impacts of developments on the environment. An EMS, on the other hand, is used to consider the key impacts of operational businesses on the environment. The main difference to note is that during the EIA process impacts on developments are predicted. A proposed development has yet to be built and therefore an element of uncertainty is associated with these assessments. With an EMS, the business or organization's processes are already in operation. Even though there is also an element of prediction involved, it is a comparatively easier task to investigate what the environmental impacts of these processes are. However, in contrast with the orientation of EIA to further development actions, EMS involves the review, assessment and incremental improvement of an existing organization's environmental effects. EMS can thus be regarded as a continuation of EIA principles into the operational stage of a policy, plan, program and project. EIA may be carried out without fully supporting necessary informations to EMS.

After the Rio declaration on environment and development in 1992, developed countries are undertaking "environmentally sustainable transportation (EST)" projects. To meet the needs for EST, current transportation policies in Korea are rapidly reforming and one of its concerns is modernizing and upgrading railway freight system. Planning new railroad construction projects is increasing and subsequent environmental impact assessment (EIA) demands improvements, especially in both the EIA and decision making systems. In this paper, we discuss the present status of EIA for railroad construction projects, especially, by analyzing the EIA documents for the last six years. The EIA for railroad construction projects accounts for only 4.9% of total 918 project EIAs during 1998-2003, and the portion is gradually increasing. Major environmental concerns for EIA in railroad construction projects were geomorphological and ecological changes, protection of rare organisms, air pollution, water pollution, waste management, and noise, etc. We compared characteristics of environmental impacts of railroad construction with those of vehicle road construction, based on environmental and construction-planning indicators appeared in Environmental Impact Statements. Railroad construction usually requires longer tunnels and bridges for a given length than those for vehicle road construction. In addition, the amounts of geomorphological and ecological changes (road-cutting, embankment, devegetation, etc.) in railroad construction were generally less than 50% of those in vehicle road construction. To develop environmentally friendly railway systems, monitoring studies for environmental impacts of railroads such as habitat fragmentation and road kills, dispersal of alien plants, tunnelling effects on groundwater and vegetation, and noise impacts are highly recommended.

We live in an age of information and an era of rising environmental awareness. As a result, efficient and judicious use of environmental information has become a prerequisite to planning and management of environmental affairs in contemporary societies. So, we have embarked on a study of Environmental Information System(EIS). In the first article, we discussed the status analysis of EIS in Korea, USA, and Japan. This study as the second project has three major components. First, it classifies items and sources of 22 EIA factors. Second, it explains building of environmental information comprising geographic and attribute data of 17 factors. Finally, the study presents applications of EIS as an alternative assessment of suitability analysis. Based on these analysis, the study makes some recommendations and conclusions.

The purpose of this study is to understand the process and characteristics of social impact caused by development projects through research and analysis on issues presented during development projects carried out in Korea. Furthermore, on the basis this analysis, this study proposes possible improvement measure environmental impact assessment for minimizing social impact of development projects in the future. Issues related to development projects are generated mainly by the following three causes. Initial social impact can occur when a development project directly causes certain changes in natural, living and social environment. Operational problems related to assessment are another cause of social impact, and it can also occur when changes in natural and living environment work in tandem with social environment sphere. Social impact of development projects is not brought about solely by changes in social environment, but is the result of interaction of factors such as changes in social, natural, living environment and problems related to assessment or operation/management. As to why the current environmental impact assessment could not provide satisfactory solution to the issues mentioned above, this study suggests the following reasons: limitations of assessment method used in social environment category, difficulties in defining assessment criteria, limitations inherent in criterion referenced assessment method, insufficient issue-making in local community, and lack of participation on the part of local residents. Possible solutions for these limitations are as follows: 1) To identify local issues in social environment category through participation of local experts in scoping stage, 2) To adopt deliberative method for local participation, 3) To utilize social survey technique.

Cutting fluid is a factor which has big effects on both machinability and environment in machining process. The loss of cutting fluids may be reduced by the optimization of machining parameters in process planning. In this study, the environmental impact of fluid loss is analyzed. The fluid loss models in milling process are constructed with the machining parameters. The models are utilized to obtain the optimal machining parameters to minimize the fluid loss. The factors with significant effects on the fluid loss are analyzed by ANOVA test. Finally, optimal parameters are suggested considering both machining economics and environmental impact. This study is expected to be used as a part of a framework for the environmental impact assessment of machining process.
