美国环境保护署宣布将试用船用空中仪器来监测船舶遵循防止船舶污染国际公约（MARPOL）附则IV的情况。
空中仪器项目最初在切萨皮克湾内湾试用，预计其试用范围将会扩展到包括属于北美空气污染排放控制区域的其它区域。
空中仪器将对船舶排放的气体进行监测和检验，以确保船舶使用的燃料油的最大硫含量不超过1%，即符合空气污染排放控制区域的要求。

US Environmental Protection Agency increase ECA enforcement
The United States Environmental Enforcement Agency (EPA) has announced that it will trial vessel fly-overs to monitor compliance with MARPOL Annex IV.
Initially undergoing trials in the upper Chesapeake Bay area, it is expected that the fly-over program will be extended to include other areas which fall under the North America Emission Control Area (NA ECA).
The fly-overs will be monitoring and testing emissions from vessels to ensure the fuel oil being used on board contains less than 1% maximum sulphur content, as required by the ECA.
