The study investigates the problems of silt protector used for mitigation measure ofsuspended sediments (SS) during coastal construction and provides their improvements basedon the field investigation and analysis of the environmental impact assessment reports for thecoastal development projects of Korea. The field investigation along west, east and south coastsof Korea reveals a variety of problems in the installation and management of silt protectorsolely used for the SS mitigation in Korea. Major problems include installation itself, low costand quality of silt protector, and maintenance. These problems superimpose the effectiveness ofsilt protector in mitigating coastal environment impact. The present study provides the specificguideline on the project type needed for the installation of silt protector, installation standardand planning, maintenance and management. The study also suggests new mitigation optionssuch as environmental window to limit the construction period and environmental dredger tocompensate for the deficits of silt protector.
To utilize a closed municipal solid waste landfill site in environmentally secure conditions, itis necessary to verify the stabilization level of landfill leachate. To assess leachate stabilization ofan open-dumping municipal solid waste landfill site (Salmi Landfill) which is located at thevicinity of Chungju Reservoir which flows into Paldang Reservoir utilized as SeoulMetropolitan water supplies, the landfill history and surrounding characteristics of the landfillsite were surveyed.In this investigation, waste, leachate, groundwater and surfacewater samples from thislandfill were physically and chemically analyzed, and the analysis results were evaluated by‘The Criteria of Landfill Waste Stabilization (CLWS)’, ‘Discharge Criteria of Landfill Leachate’,‘The Criteria of Domestic Use in Groundwater Quality’, and ‘The Criteria of Domestic Use inSurfacewater Quality’ that promulgated by Korean Ministry of Environment.From the analysis results on the Salmi open-dumping landfill, C/N ratio was 18.9 andBOD/CODCr ratios in leachate were higher than 1/10. Based on the CLWS, this results seemedto imply that the process of leachate stabilization at this landfill was still proceeding.
During the last decade, Health Impact Assessment (HIA) has been discussed worldwide asbeing an important tool for the development of healthy public policy. HIA has been advanced as ameans of bringing potential health impacts to the attention of policy makers, particularly in sectorswhere health impacts may not otherwise be considered. HIA, a systematic assessment of potentialhealth impacts of proposed public polices, programs, and projects, offers a means to advancepopulation health by bringing public health research to bear on questions of public policy.In Korea, health-related items under current EIA (Environmental Impact Assessment) systemcan only be found in the categories of hygiene and public health. However, environment andpublic health are not adequately connected and also health is underestimated even thoughhealth is an important objective component for the implementation of EnvironmentalAssessments (EA). As a result, health is not well integrated within criteria for investigating theimpacts on environment.This study examines linkages for HIA from the related and relatively well-developed field ofPrior Environmental Review System (PERS) which is similar to SEA and EIA in Korea.
