MARPOL (Maritime Pollution Treaty) 부속서 (Annex VI) 경우 대기오염 규제 내용이며, 최근 선박 배기가스 배출규제 강화 목적 개정됨에 따라 관련 규정을 충족하기 위한 적극적인 조치가 요구된다. 예를 들어 Sulfur Dioxide (SOx, 황산화물) 경우 2020년 기준 전 세계 해역 내 운항하는 선박은 황 함유량 0.5% 기준의 배출 요구 기준을 충족해야 한다. 배출규제 해역 지정 시 해당 해역 선박 배기가스 배출량 계산 산정 기준 확립이 필요함에 따라 대기환경에 대한 종합적인 분석이 필수적으로 요구된다. 본 연구에서는 황산화물 배출량 산출 방법론으로써 그리드 셀 내 선박 점유시간을 계산한다. 점유시간이 길수록 선박 통항 및 배기가스 배출이 밀집되어 있음을 의미한다. 밀집도 분석에 더불어 선박의 특성이 반영된 시간당 배출량을 적용하여 배출 공간 인벤토리를 구축하였으며 분석 결과를 GIS (Geographical Information System) 환경에서 공간 지도로 시각화하였다. 기존 국내 황산화물 배출규제 해역의 효과 평가에 더불어 외항 범위까지 규제 확대 시나리오확립 후 비교 평가를 통하여 배출량 감소 효과를 정량적으로 확인하였다.

In this paper, the current status of marine industrial facilities, regulatory legal systems, and emission status of hazardous and noxious substances (HNS) in these facilities were analyzed, and the direction of improvement of the regulatory system was presented accordingly. As a result of the analysis, it is estimated that about 1,100 marine industrial facilities are subject to the Marine Environment Management Act of 2007. It is estimated that 190 kinds of hazardous substances are discharged from these marine industrial facilities and are highly likely to flow into the ocean, of which 20 are estimated to be discharged into the water system. However, due to the lack of relevant laws and regulation, it is difficult to clearly determine whether the discharged material corresponds to an exceptional discharged material, making it difficult to effectively enforce regulations in the field. For this reason, effective regulatory enforcement is difficult in the regulatory field. The marine environment management law should clearly stipulate the exceptional emission standards and types of substances, and clarify the selection system, risk assessment system, and emission information collection and monitoring system for related Hazardous and Noxious Substances.

It is necessary to establish a marine environment management system in Korea for hazardous noxious substances (HNS) effluent from marine industrial facilities because the Marine Environment Management Act primarily focuses on pollution control from vessels and offshore man-made structures. In this study, we investigated the effluent guidelines of foreign cases focusing on the US Environmental Protection Agency (US EPA), which provides detailed information on the action levels and establishing principles for the industrial wastewater discharge of HNS. Based on the review, we also considered appropriate options for establishing new guidelines for Korea.

Traditionally, UNCLOS stipulates that States have the obligation and responsibility to protect and preserve the marine environment and exercise their rights in Principle of Non-Discrimination with respect to foreign ships visiting to port states. UNFCCC and Kyoto protocol established Common but Differentiated Responsibility as the basis which is established on the historic responsibility. The principle in which IMO is presently developing the regulations of Green House Gas emitted from ships is contradict with the principle of UNFCCC regime. In this paper, the development and the principle of UNFCCC and Kyoto protocol is surveyed and it provides the tendency of the IMO activities regarding GHG emission from ships. Also, through consideration of the problems and restrictions drawn from comparison between two principles, the conclusion suggests the fundamental theory and implementation means in order to carry out the purpose of IMO regulations in accordance with the principles of UNCLOS and IMO Convention.

최근 전 세계적으로 수송수단과 산업시설에서의 배출로 인한 대기오염의 심각성을 강조하고 있다. 특히 항만과 공항에서도 대기오염의 중요성을 인지하고 있고 지역별 대기오염물질 배출 및 대기오염도 현황을 분석하여 각 시설에서의 종합관리방안을 도출하고 있다. 2020년부터 시행되는 국제해사기구(IMO)의 선박에서 배출되는 온실가스 즉, 황성분을 포함한 연소배기가스 중 CO2, SOX,NOX, PM2.5의 배출규제에의 대응과 배출규제해역(ECA)제도 도입에 따른 업계와 정부, 학회의 대비도 빠르게 진행되고 있다. 부산항에서도 항내계류선박과 하역장비에서의 오염물질 배출을 억제하기 위한 대체전력공급(AMP, Cold Ironing)에 대해 대응하고 있다. 본 연구는 도시주민의 건강을 위협하는 미세먼지(PM2.5)의 심각성과 배출가스의 저감을 위한 방안을 소개하고 오히려 이를 해운항만에서의 4차산업 발전의 계기로 대응하도록 하는 방향을 제시하고자 하였다. 산업화 과정에서 필연적인 대기오염을 저감시키는 방안이 새로운 해양산업으로 전환하기를 기대한다.

세계 해양환경의 보전을 위하여 설립된 UN 기구인 국제해사기구(IMO)에서는 해양환경 오염물질 등에 대한 규제강화를 위하여 최근 새로운 해양환경협약의 채택 및 발효를 강력히 추진해 오고 있다. IMO의 국제협약은 선박이라는 효과적인 제어수단을 통하여 가장 강력한 통제력을 갖는 협약으로 세계 모든 해양국의 해양환경에 관한 국제법의 성격을 띄고 있다. 구속력이 강력한 만큼 변화되는 국제협약에 의해 새롭게 창출되는 해양환경시장의 규모가 엄청나므로 당사국들이 서로 자국의 이익을 위해 올인하는 전형적인 그린라운드의 양상을 띄고 있는 현실이다. 우리나라는 국제해사기구의 A그룹 이사국이며 아울러 세계 제일의 조선대국, 또한 세계 6위의 해양대국으로서의 국제적인 위상을 감안할 때 해양환경 보호를 위하여 현재 발효되고 추진 중에 있는 협약에 대한 연구와 효과적 대처를 하여야 함은 물론 우리나라 조선, 해양산업이 보호되고 나아가 이익이 창출될 수 있는 방향으로 모든 국제협약이 이루어지게 노력해야할 것이다. 이 논문은 해양관련 환경규제 협약인 Marpol 73/78 협약, 선박의 유해방오도료 사용규제협약, 평형수 배출규제협약, 선박으로부터 오수에 의한 오염방지를 위한 협약, 대기오염방지협약 등의 주요 현안을 파악하고 분석하여 이에 따른 현실적인 대응책을 제시하고자 한다.

Air pollution associated with the SOx emission from the shipboard propulsion and generation engines is becoming one of the major environmental concerns these days. Lead by the international organizations including IMO and European Union, a significantly strengthened air pollution related regulations have been introduced and they are becoming in practice as scheduled. Such rules are basically giving the guidelines for permissible SOx emission which can be only met by using high quality fuel oils with less sulfur content or operating scrubbing systems aiming at reducing SOx at the engine exhaust. Since both countermeasures can lead to the cost increase in ship building and operation, Korean shipbuilding industries, leading the world's market, need to be well aware of the ever changing regulations and be prepared with proper solutions. Here, we briefly summarize such latest rules and regulations on the air pollution at sea, and review some technical issues on the scrubbing systems available with some suggestions.

Since ocean dumping of wastes was permitted by law in 1900, the amount of wastes dumped into the sea has increased ten times for 15 years. As a result, the dumping sites has been deteriorated so much that the pollution has become a social problem. The 96 Protocol to the 72 London Convention, which requires the contracting party's stricter control on the disposal of wastes at sea, took effect on March 24, 2006. Therefore, our country has become confronted to the situation on which it cannot delay putting a restraint on ocean dumping. Hereupon, Korea Coast Guard (KCG) initiates a dumping sites recovery program. The program is intended to curb the amount of wastes dumped at sea and to recover the polluted dumping sites. In this paper, the current status of our country's management of ocean dumping of wastes is examined and the future condition is anticipated KCG's ocean dumping management measures are also presented.

Domestic marine diesel engine makers reduce the NOx emission mostly by applying low NOx fuel nozzle and injection timing retard. However, it is necessary to develop high efficient technology (EGR, DWI and SCR, etc.) to reduce NOx emission in order to prepare for the further reinforcement of the NOx emission limit. Also, in the near future, IMO will restrict additively THC, PM and CO with NOx. Therefore, domestic engine makers have to prepare for it and the relevant government ministries should give a sufficient support to these technology research and establish or amend the relevant law, which should include the excursion riverboat.
