"This was a highly unique project that had never been attempted anywhere in the United States in a river at this scale," Dominion Energy South Carolina President Keller Kissam said. "Its successful completion is a testament to the excellent coordination and relationships among our employees, regulators, contractors and stakeholders who helped guide the work. There were many who doubted that it could be done, but I'm here today to say proudly that not only did our exceptionally talented and dedicated team do it, they did it in a manner that sets the example for others to follow."
Crews removed tar-like material in the Congaree riverbed that was first discovered in June 2010. Dominion Energy committed to remediating the material after lab testing showed it was consistent with coal tar created at a manufactured gas plant located near what is now the South Carolina State Museum and operated by predecessor companies approximately a century ago. The plant produced gas from coal, oil and other feedstocks, which was used for lighting, cooking and heating Columbia homes and businesses.
