  • Several fine particle-related policies in Northeast United States were investigated in support of the execution of special measures to improve air quality of Seoul Metropolitan Area (SMA). The definition of particulate matter (PM) in the Clean Air Act (CAA), components and procedures of Regional Haze Rule (RHR), and Air Quality Management (AQM) were reviewed. Several State Implementation Plans (SIPs) were also reviewed as the way to attain required air quality under the Clean Air Act. $PM_{2.5}$ attainment SIP of Maryland, 8-hr Ozone attainment SIP of New Jersey, and Regional Haze Rule attainment SIP of MANE-VU were analyzed in detail as case studies. We realized that "Special Measures for Air Quality Improvement in the Seoul Metropolitan Area" has many similarities with its US counterparts in terms of purpose, components, procedures, and implementation methods. US policies, however, have more advanced features, such as standardized procedures and methods, transparent guidelines, and stable relationship among federal/state/local governments and stakeholders, which would be helpful to improve air quality in SMA.

  • Pollution emissions from international shipping and port activities have a significant impact on public health and global climate changes. The purpose of this paper is to review the status of pollution mitigation measures implemented to date in port industry and find out some implications for Korean ports. For this aim, the clean air strategies of the world major ports including six USA ports (Los Angeles/Long Beach, Now York/New Jersey, and Seattle and Tacoma), two European ports (Rotterdam and Gothenburg) and Busan Port were considered. Various measures to reduce emission from ports are evaluated by sectors-ocean going vessels, cargo handling equipments, truck and rail-, on the basis of categories such as reduction control technologies, operational changes and market-based measures. The policy implications of this paper are as follows. First, Clean Air Act Plans of Korean ports are required as soon as possible. Second, integrated approach is required to reduce emission effectively. Finally, the effect of port-related emission reduction can be maximized when various measures are conducted on a regional basis including neighboring ports. Furthermore, regional or global-based approach is useful to guarantee the level playing field among ports.

  • This study was reviewed on the bioethanol production from biomass resources and feedstock supply in America. U.S. Department of Energy (USDE) and the u.s. Department of Agriculture USDA) are both strongly committed to expand the role of biomass as an energy source. They support biomass fuels and products as a way to reduce the need for oil and gas imports, to strengthen the nation's energy security and environmental quality. And it was envisioned a 20 percent replacement of the current U.S.transportation fuel consumption in 2030. Also it was reviewed policies to encourage the expanding of Bio-based fuel use to replace gasoline, such as Clean Air Act, Federal Clean Fuel Program and American Jobs Creation Act. In feedstock supply it was assumed forest biomass will be supplied in 368 million dry tons yearly and the agriculture derived biomass adopted by new technologies and land use change will be supplied in 998 million dry tons, including highly 818 million dry tons of lignocellulosic biomass such as perenial crops (hybrid trees, grasses) corn stover, other crop residues. This amount is 5 times to the amount from based current agricultural technology and crop land.

  • 휘발성유기화합물 (VOCs)은 복잡 다양한 발생원에서 배출되고 있다. 1990년에 개정된 미국 공기청정법 (US Clean Air Act Amendments, CAAA)에서는 총 189개의 화합물을 인간환경에 유해한 유해 대기 오염물질 (HAP, hazordous air pollutants)로 분류하고 있다 (MacKensie, A.R 등, 1991). 이 중 미국 EPA에서는 유해 대기오염물질로서 43개의 VOCs를 정하여, TO-14 화합물로서 일컫고 있다 (허귀석, 1999). (중략)

  • 각종 연소기반의 오염 배출원에서의 수은을 비롯한 중금속의 배출은 많은 우려를 낳고있다. 이미 미국에서는 1990년 Clean Air Act Amendments를 통해 11개의 중금속의 (As, Be, Cd, Co, Cr, Hg, Mn, Ni, Pb, Sb, and Se) 배출을 가장 효과적인 적용 가능한 기술로서 그 배출을 제어하도록 되어있다. 그 중에서도 특히 수은은 다른 중금속과는 달리 높은 휘발성, 강한 유해성, 그리고 체내에 축적이 되는 특성으로 해서 더욱 관심의 대상이 되고 있다. 또한 수은은 연소장치에서 대기중으로 배출시 다른 중금속이 입자의 형태로 배출되는 것과는 달리 주로 원소상태의 기체로 배출되는 것으로 알려져 있다.

  • Managing hazardous air pollutants (HAPs) becomes an important issue with the amendment of the Clean Air Conservation Act in 2012. In this study, to develop an effective air quality management policy direction against the HAPs in Korea, (1) the HAPs control policies in the USA, United Kingdom, Japan, and the South Coast Air Quality Management District (SQAQMD) are reviewed, (2) the state of the art of the HAPs management in Korea are studied, and (3) policy directions are suggested. It was found that each country has its own policy priority and management directions. It was also found that the current HAPs management status is far behind to the countries compared in HAPs identification, emission inventory, monitoring, modeling, and risk management. Further policy directions are suggested.

  • To comply with the regulation of the reinforcing Clean Air Conservation Act, it is necessary for the semiconductor manufacturers to develop effective low-concentration acid gas abatement system to treat the flue gas. The low-concentration acid gas was found to be harder to deal with than the high-concentration one. In this study, the effect of various potential treatments such as air-assist nozzle spraying, magnetizing the scrubbing water, and adding surfactants to spraying and scrubbing water were investigate through the application of the statistical ANCOVA method, which was proved to be very useful tool when the inlet concentration of acid gas could not be controlled precisely and it affected the removal efficiency of the abatement system.

  • 대기오염물질 중 수은화합물질은 생태계와 인간에게 치명적인 독성과 생물농축의 특성 때문에 유해한 물질로 관리되어왔으며, 1990년 미국의 Clean Air Act Amendment(CAAA)의 188개의 대기오염물질대기오염물질(HAPs) 중의 하나이고, 국내에서도 25종의 특정대기유해물질 중의 하나로 관리되고 있는 물질이다. 미국 EPA의 보고서에 따르면, 수은화합물의 주요 배출원은 석탄 화력발전소를 비롯한 도시폐기물소각로, 유해폐기물소각로, 병원폐기물소각로 등의 연소설비가 미국 전체 연간 수은배출량의 약 87%를 차지하는 것으로 나타나 주요 배출시설에 대한 관리가 요구되는 것으로 나타났다(US EPA 1997,1998).

  • The objective of this study is to provide information for improving the domestic particulate matter (PM) management. To achieve the study goal, we reviewed the past and current practice of PM management in the United States (US). Our review includes the assessment about the philosophical foundation and effectiveness of PM management, systematic program implementation to reach desirable PM conditions, and steady development of analytical tools including photochemical air quality models. We noticed that the current US PM management approach has improved annual $PM_{2.5}$ concentrations 22-48% in various parts of the US in the last 16 years. In addition, we analyzed strengths and difficulties in the past US PM management implementation. Based on the results of our analyses, we propose key elements to establish more effective domestic PM management in the future than now: steady investment in technological innovations and close-communications between local governments and the central government at various stages of PM management.
