Only one vessel was loading coal at the time of our flight, the Panama-flagged Grand Diva. This operation was depositing a black plume of coal dust in the water.

As an individual case, this may not result in a significant impact on the environment. But a brief review of Google Earth’s historical imagery yields two previous events clearly showing coal in the water, and several other less-clear images that appear to show pollution, suggesting this is a common event that may result in significant cumulative impact.
Air pollution is another consideration. Chronic coal-dust blowing off the stockpiles at a coal terminal are the basis of a Clean Water Act lawsuit in Seward, Alaska, and one of the main arguments throughout the Pacific Northwest against expanding coal export terminals to move more Powder River Basin coal from Wyoming to Asian markets. This is only one step along the way from mine to market – coal trains derail far more often than you might think (in North Dakota, Michigan, and Nebraska, just this past month), loaded barges crash into bridges (just this week), terminals flood when severe storms come through, and ships even crash into the loading docks. Not counting carbon emissions from burning the coal, scientists, environmentalists, and concerned citizens along coal transport routes are worried that these cumulative impacts will harm public health, disrupt their daily lives, and negatively impact the ecological health of waterways along the path from mine to port.
|Bulk transport by barge is cheaper and more fuel efficient than even freight rail, but extreme weather events exaggerated by climate change threaten its reliability. Last year’s drought crippled transport on the Mississippi River at the end of 2012, and without significant rain river operators could face another low water crisis in 2013.|
More to come including a leaky settling pond, an oil slick off Gulfport, and severe erosion resulting from ill-conceived oil spill response practices on Dauphin Island. Be sure to check out the photos of the whole flight on Flickr.
