Ingram Barge Company retrofitted six towboats with diesel oxidation catalyst (DOC) units.  This led to reductions in particulate emissions of about 40% and reductions in carbon monoxide and hydrocarbon emissions by over 60%.  As a SmartWay transport partner, the Ingram Barge Company will continue to seek out innovative technology and partner organizations to work with such as its partnerships on this project with the Mississippi River Corridor – Tennessee (MRCT), Environmental Solutions Worldwide Inc. (ESW) and Emisstar.
