  Investigation of Fugitive Emissions from Petrochemical Transport Barges Using Optical Remote Sensing (EPA/600/R-09/136) September 2009

Recent airborne remote sensing survey data acquired with passive gas imaging equipment (PGIE), in this case infrared cameras, have shown potentially significant fugitive volatile organic carbon (VOC) emissions from petrochemical transport barges. The experiment found remote sensing techniques useful for identification and assessment of fugitive emissions from difficult to monitor sources such as barges. The study included aerial PGIE surveys of barges on the Mississippi River to find significant fugitive emissions. Additional ground based PGIE observations of barges from a lock wall and onboard barges were conducted to closely examine leaks and identify their components. Some leaks were captured in plastic bags, the leaks having been identified by remote sensing. In addition, EPA method OTM 10 using open-path Fourier transform infrared spectroscopy was used to product hydrocarbon emission measures from barge traffic in locks.
